I. Executive Summary

A. Purpose

    This proposed rule would update provisions related to Exchange 
eligibility and verification consistent with new requirements specified 
under section 71303 of Public Law 119-21 (July 4, 2025), which we refer 
to as the Working Families Tax Cut (WFTC) legislation. We solicit input 
on ways Exchanges can strengthen certain verifications to promote 
program integrity while minimizing unnecessary or duplicative 
administrative burdens to the extent practicable. This proposed rule 
also contains related updates to provisions affecting inconsistency 
periods, enrollment options during inconsistency verification 
procedures, annual eligibility redeterminations and eligibility 
redeterminations during the plan year. It also expands enrollment 
methods during the verification process and establishes new effective 
dates.

B. Summary of Major Provisions

    We propose to modify 45 CFR 155.106 to require that the 15-month 
requirement for a State to submit its application for HHS' review and 
approval be oriented around when a State begins operations as a State

[[Page 67657]]

Exchange for the pre-open enrollment (pre-OE) verification period, 
instead of the Open Enrollment period (OEP).
    We propose to retain the existing regulatory requirements in Sec.  
155.315(d) related to verification of residency. We seek comment on how 
HHS might strengthen requirements for Exchanges to verify residency in 
the short and long term to improve program integrity, and ideas on how 
Exchanges can move away from primarily accepting self-attestation of 
residency without further verification.
    We propose to amend Sec.  155.315(f)(4)(ii) to state that Exchanges 
would not be able to authorize payment for advance payments of the 
premium tax credit (APTC) and cost-sharing reductions (CSRs) for 
applicants who have data matching issues (DMIs) described in Sec.  
155.315(c) for citizenship \1\ and lawful presence status; Sec.  
155.315(d) for residency; Sec.  155.320(b) for non-employer sponsored 
minimum essential coverage (MEC); \2\ Sec.  155.320(c)(3) for annual 
household income, family size, and eligible noncitizen status; and 
Sec.  155.320(d) for employer-sponsored plans, until such DMIs are 
adjudicated by the Exchange, if otherwise eligible. Additionally, we 
propose in Sec.  155.315(f)(4)(ii) that the above requirement would not 
apply if the applicant's tax household is eligible for a special 
enrollment period (SEP) described in Sec.  155.420(d)(2)(i) or (ii).
---------------------------------------------------------------------------

    \1\ When referring to verification of ``citizen'' or 
``citizenship'' status in this proposed rule, we are also referring 
to verification of status as a U.S. National. U.S. Nationals are 
defined as ``A person who, though not a citizen of the United 
States, owes permanent allegiance to the United States (for example, 
persons born in American Samoa or Swains Island).'' Please see 
<a href="https://www.uscis.gov/glossary-term/50718">https://www.uscis.gov/glossary-term/50718</a>.
    \2\ References to minimum essential coverage or MEC throughout 
this rule may refer to coverage through an employer-sponsored plan 
or other coverage, such as Medicaid. References to ``other MEC'' 
throughout this rule are intended to refer to coverage other than 
Exchange coverage.
---------------------------------------------------------------------------

    We propose to add new Sec.  155.315(f)(4)(iii) to describe the 
requirements related to providing APTC and CSRs for enrollees who have 
reported a change to eligibility criteria during the plan year after an 
Exchange has completed verification of those same criteria. We also 
propose to add new Sec.  155.315(f)(4)(iv) to specify that Exchanges 
would be required to determine eligibility for APTC and CSRs on behalf 
of an applicant following successful verification of information as 
described in proposed new Sec.  155.315(f)(4)(ii) and to establish 
effective dates of those eligibility determinations or 
redeterminations. We also propose to add new Sec.  155.315(f)(4)(v) to 
state that applicants with DMIs unrelated to the information outlined 
in proposed Sec.  155.315(f)(4)(ii) receive APTC and CSRs during an 
inconsistency period if otherwise eligible, as currently required. We 
further propose to add new Sec.  155.315(f)(4)(vi) to move the 
requirement that a tax filer must acknowledge that any APTC are subject 
to reconciliation that is already outlined in existing Sec.  
155.315(f)(4)(ii). Finally, we propose to amend Sec.  155.315(f)(4)(i) 
to remove language around proceeding with all other elements of 
eligibility determination to align with proposed changes to Sec.  
155.315(f)(4)(ii).
    We propose to retain the existing regulatory requirements at Sec.  
155.320(c) related to verification of family size, and we seek comment 
on how we might strengthen requirements for Exchanges to verify family 
size to improve program integrity.
    We propose to amend Sec.  155.330(f) to specify effective dates for 
eligibility redeterminations during the plan year. Specifically, we 
propose that eligibility redeterminations resulting from enrollee-
reported changes would be effective on the first day of the month 
following the eligibility redetermination, unless the enrollee 
qualifies for certain SEPs. At Sec.  155.330(f)(2), we propose to add 
cross-references to the newly proposed effective date rules at Sec.  
155.315(f)(4)(iv) that apply when an Exchange resolves a consumer's DMI 
described in Sec.  155.315(f)(4)(ii) or Sec.  155.315(f)(4)(iii)(A). 
Finally, at Sec.  155.330(f)(3), we propose effective date rules for 
consumers whose DMIs are expired because they do not submit sufficient 
documentation.
    We propose to amend Sec.  155.335 to require that Exchanges 
continue redetermining the eligibility of an enrollee on an annual 
basis but newly require that an Exchange may not redetermine an 
enrollee eligible for APTC and CSRs for the subsequent plan year unless 
the enrollee or the enrollee's application filer provides or confirms 
household income and family size; U.S. citizenship or status as an 
eligible noncitizen; eligibility for or enrollment in other MEC; and 
place of residence for the subsequent plan year on or after August 1 
and no later than December 31 of the year preceding the applicable plan 
year, and the Exchange would be required to attempt to verify the 
specified eligibility information using the processes in Sec. Sec.  
155.315 and 155.320, including the relevant provisions in those 
sections regarding DMIs.
    We also propose to amend Sec.  155.335(b) to state the annual 
eligibility redetermination would be effective on the first day of the 
applicable plan year, and the Exchange would be required to adhere to 
the existing notification standard for eligibility determinations under 
Sec.  155.310(g). We propose an exception in instances where an 
enrollee has an unresolved DMI under Sec.  155.315(f)(4)(ii) as of 
December 31 of the year preceding the plan year and for whom APTC and 
CSRs are not provided during the inconsistency period. In these cases, 
we propose that the redetermination of APTC and CSRs take effect in 
accordance with Sec. Sec.  155.315(f)(4)(iv)(A) or 155.330(f)(3), as 
applicable. We propose to remove Sec.  155.335(c) through (i); 
redesignate Sec.  155.335(j) as new Sec.  155.335(c); and remove Sec.  
155.335(k) through (n).
    We propose to modify Sec.  155.400(e) to account for new enrollment 
requirements proposed in this rule. Specifically, we propose that 
Exchanges may, and the Federally-facilitated Exchange (FFE) and State-
based Exchanges on the Federal platform (SBE-FPs) would be required to, 
make retroactive enrollments under proposed Sec. Sec.  
155.410(f)(5)(i)(A) and (B), 155.410(f)(ii)(A) and (B), and 
155.420(b)(6)(i), subject to the current binder payment rules for 
retroactive enrollments under Sec.  155.400(e)(1)(iii). We also propose 
to make conforming amendments at Sec.  155.400(e)(1), including 
combining current (i) and (ii) as proposed (i), and redesignating 
current (iii) as proposed (ii).
    We propose to add new Sec.  155.400(i) to require that Exchanges 
permit applicants and enrollees to ``pend'' their plan selection such 
that the plan selection would only be sent to the issuer, and qualified 
health plan (QHP) coverage only becomes effective, after the Exchange 
determines the applicant or enrollee eligible for APTC and CSRs, as 
applicable, as described by Sec.  155.315(f)(4)(iv).
    We propose to add Sec.  155.410(h) to require all Exchanges to 
provide a pre-OE verification period during which Exchanges would 
enable consumers to choose to provide certain eligibility information 
for the subsequent plan year. Exchanges would be required to attempt to 
verify such information provided. We propose that the pre-OE 
verification period for all Exchanges begin each year on August 1 and 
continue until an Exchange's OEP begins.
    We propose new effective date rules for pended plan selections made 
during the annual OEP or during an SEP, in Sec.  155.410(f)(5) and 
Sec.  155.420(b)(6), respectively. These rules would provide

[[Page 67658]]

that, in general, if an Exchange resolves all of a consumer's DMIs 
described in Sec.  155.315(f)(ii) by the 15th of the month following 
the consumer's otherwise prescribed effective date under Sec.  
155.410(f)(5) or Sec.  155.420(b)(6), then the consumer can maintain 
that coverage effective date. If, however, they do not resolve all of 
their DMIs by the 15th of the month following their otherwise 
prescribed effective date, then their coverage effective date would 
depend on when their DMIs were resolved. If their DMIs were resolved by 
the 15th of the month, their coverage effective date would be the first 
of the month of resolution. If their DMIs are resolved between the 16th 
and the end of the month, then their coverage effective date would be 
the first of the following month.
    We are considering expanding the application submission timeframe 
described in the SEP at Sec.  155.420(d)(11), which is commonly 
referred to as the Medicaid denial SEP, and seek comment on this 
possible change. For this SEP, if a consumer applies for Medicaid and 
CHIP coverage, either through the Marketplace eligibility application 
or directly with the State Medicaid or CHIP agency during the OEP and 
is denied Medicaid and CHIP, the consumer is granted an SEP to gain 
access to Exchange coverage. Specifically, we seek comment on whether 
consumers who apply for Medicaid or CHIP during the pre-OE verification 
period should also be eligible for this SEP, if otherwise eligible.

II. Background

A. Legislative Overview

    The Patient Protection and Affordable Care Act (Pub. L. 111-148) 
was enacted on March 23, 2010. The Health Care and Education 
Reconciliation Act of 2010 (Pub. L. 111-152), which amended and revised 
several provisions of the Patient Protection and Affordable Care Act, 
was enacted on March 30, 2010. In this proposed rule, these statutes 
are collectively referred to as the Affordable Care Act.
    Section 1311(b) and (c)(6) of the Affordable Care Act outlines 
provisions for the establishment of Exchanges that facilitate the 
purchase of insurance coverage by qualified individuals through QHPs 
during an annual OEP or SEP. Section 1401 of the Affordable Care Act 
created section 36B of the Internal Revenue Code (Code), which provides 
for a premium tax credit (PTC) for eligible individuals who enroll in a 
QHP through an Exchange. Section 1402 of the Affordable Care Act 
establishes provisions to reduce the cost-sharing obligations of 
certain eligible individuals enrolled in a QHP offered through an 
Exchange through the provision of CSRs.
    Under section 1411 of the Affordable Care Act, the Secretary of HHS 
is directed to establish a program for determining whether an 
individual meets the eligibility standards for enrollment in a QHP 
through an Exchange, APTC, and CSRs. Section 1411(b) of the Affordable 
Care Act specifies the information to be provided by applicants for 
enrollment in QHPs offered through an Exchange, including what is 
required for applicants seeking APTC and CSRs. This applicant 
information may include names, addresses, dates of birth, and Social 
Security Numbers; information about citizenship and immigration status; 
and, for individuals applying for APTC and CSRs, information about 
household income, family size, and offers of health coverage from 
employers. Section 1411(c) of the Affordable Care Act requires 
Exchanges to submit certain applicant information to specified data 
sources for verification of its accuracy. Section 1411(c)(4) of the 
Affordable Care Act generally requires verifications of certain 
applicant information to be performed electronically using online 
systems. However, section 1411(c)(4)(B) of the Affordable Care Act 
grants HHS flexibility to modify the methods of such verifications to 
reduce administrative costs and burden on applicants, and section 
1411(d) of the Affordable Care Act delegates to HHS responsibility for 
the manner in which certain other verifications are completed.
    Consistent with the requirements of section 1411 of the Affordable 
Care Act, when an applicant applies through an Exchange, they attest to 
information on the application, such as their citizenship or 
immigration status, and their household's expected annual income. As 
part of the application process, Exchanges check trusted data sources 
to determine if application information is reasonably compatible with 
information from those data sources. In cases where the information is 
not reasonably compatible or data is unavailable, generally the 
applicant will receive notification of a data matching issue (DMI). 
Consistent with additional requirements of section 1411(e) described 
below, the applicant will have 90 or 95 days to resolve the DMI by 
submitting requested documentation. The applicant will be provided 95 
days for document submission for DMIs related to the verification of 
citizenship or immigration status. Throughout this proposed rule, we 
refer to this 90/95-day period as an ``inconsistency period,'' and we 
refer to instances where an applicant has an inconsistency as the 
applicant having a DMI.
    Section 1411(e)(2)(A) of the Affordable Care Act establishes that 
when certain information has been verified, an applicant becomes 
eligible to enroll in a QHP through an Exchange, and for APTC and CSRs, 
as applicable. Section 1411(e)(3) of the Affordable Care Act specifies 
the process Exchanges must follow when applicants have a DMI related to 
citizenship or immigration status by referencing section 1902(ee) of 
the Social Security Act. In the March 27, 2012 Federal Register (77 FR 
18310) (Exchange Establishment Rule), we interpreted this to require 
the Exchange to notify applicants of their DMI and provide them an 
opportunity to submit evidence to verify their information within 95 
days from the date the notice is received. In the Exchange 
Establishment Rule, we also interpreted section 1411(e)(3) of the 
Affordable Care Act as requiring Exchanges to make eligibility 
determinations on the basis of information provided on the application 
during an inconsistency period related to citizenship or immigration 
status.
    Similarly, section 1411(e)(4)(B)(i) of the Affordable Care Act 
requires that Exchanges make eligibility determinations on the basis of 
information provided on the application during an inconsistency period 
related to information other than citizenship or immigration status. 
This means that applicants with a DMI may be able to enroll in a QHP 
and receive APTC and CSRs during an inconsistency period, if eligible 
based on the information provided on their application. Section 
1411(e)(4) specifies the process Exchanges must follow when applicants 
have DMIs, other than those related to citizenship or immigration 
status, including notifying applicants and providing them an 
opportunity to submit evidence to verify their information within 90-
day inconsistency periods.
    Under section 36B of the Code, a taxpayer is only allowed a PTC for 
months that are coverage months for the taxpayer or other individuals 
in the taxpayer's family (a taxpayer's family consists of the taxpayer, 
the taxpayer's spouse if filing a joint tax return, and the taxpayer's 
tax dependents). Section 71303(a) of the WFTC legislation amends 
section 36B of the Code to provide additional requirements before a 
month can be a coverage month, effective for tax years beginning after

[[Page 67659]]

December 31, 2027.\3\ Effective January 1, 2028, section 36B(c)(5)(A) 
of the Code provides that a month is generally not a coverage month for 
an enrollee in a QHP unless an Exchange ``verifies'', ``using 
applicable enrollment information that shall be provided or verified by 
the applicant,'' the enrollee's eligibility to enroll in a QHP through 
an Exchange and, to the extent relevant, for APTC for the coverage for 
that month. In this proposed rule, we use the term ``confirm'' as a 
synonym to ``verify'' when referring to the requirement in section 
36B(c)(5)(A) of the Code that information shall be ``verified by the 
applicant.'' We reserve the term ``verify'' to describe the section 
36B(c)(5)(A) of the Code requirement for Exchanges to verify 
eligibility. This terminology avoids confusion throughout this proposed 
rule about which subject of the statute (that is, ``the Exchange'' or 
``the applicant'') is the subject of the term ``verify.'' Section 
36B(c)(5)(B) of the Code provides, ``applicable enrollment 
information'' referenced in subsection (c)(5)(A) includes, to the 
extent relevant: (i) household income and family size of the enrollee, 
(ii) whether the enrollee is an eligible alien, (iii) any health 
coverage status or eligibility for coverage, (iv) the enrollee's place 
of residence, and (v) such other information as may be determined by 
the Secretary of the Treasury (in consultation with the Secretary of 
HHS) as necessary to the verification prescribed under section 
36B(c)(5)(A) of the Code.
---------------------------------------------------------------------------

    \3\ See section 71303(c) of the WFTC legislation.
---------------------------------------------------------------------------

    Section 36B(c)(5)(C) of the Code allows months that begin before 
the verification required by section 36B(c)(5)(A) of the Code to be 
considered coverage months if an Exchange completes the required 
verification for those months. Section 36B(c)(5)(D) of the Code 
provides that a consumer must not be treated as ineligible to enroll in 
a QHP solely for failing to meet the requirements of section 36B(c)(5) 
of the Code for a month. Section 36B(c)(5)(E) of the Code delegates to 
the Secretary of the Treasury authority to waive the verification 
requirements of section 36B(c)(5)(A) of the Code for individuals who 
enroll in a QHP during an SEP granted due to a change in family size.
    Section 71303(b) of the WFTC legislation added new section 
36B(c)(3)(A)(ii) of the Code. This change modifies the definition of 
QHP for the purpose of section 36B of the Code. Specifically, it 
excludes from the definition of QHP any plan that is enrolled in 
through an Exchange that does not provide a process through which any 
consumer may verify their household income and eligibility for QHP 
enrollment for the following plan year. This process must be in place 
no later than August 1, 2027 (and by August 1 for each subsequent year) 
to ensure applicants and current enrollees in QHP coverage who are 
seeking QHP coverage with APTC for plan year (PY) 2028 and subsequent 
years remain eligible for PTC and APTC, if otherwise eligible.
    Section 71305 of the WFTC legislation removed section 36B(f)(2)(B) 
of the Code. This change eliminated the limitation on repayment of 
excess APTC for tax years after December 31, 2025.

III. Provisions of the Proposed Regulations

A. Part 155--Exchange Establishment Standards and Other Related 
Standards Under the Affordable Care Act

1. Election To Operate an Exchange After 2014 (Sec.  155.106)
    We propose to amend Sec.  155.106(a)(2) to require an Exchange 
submitting a Blueprint application to do so at least 15 months prior to 
the date on which it proposes to begin its pre-OE verification period 
instead of at least 15 months prior to the date on which it proposes to 
begin its OEP. In section III.A.9.c. of this proposed rule, we are 
proposing to add Sec.  155.410(h) to require that all Exchanges permit 
consumers to provide eligibility information to Exchanges for the 
upcoming plan year prior to the beginning of the OEP each year, 
beginning on August 1, 2027, for PY 2028 and August 1 of each 
subsequent year. Accordingly, we have considered the implication of the 
new proposed pre-OE verification period on our current requirements and 
process for approval of States currently utilizing the Federal 
platform, as an FFE or SBE-FP, that wish to establish a State Exchange.
    As part of the State Exchange establishment process under 45 CFR 
Part 155, subpart B, we currently require at Sec.  155.106(a)(2) that 
any State on the Federal platform that intends to establish and operate 
a State Exchange must submit its Exchange Blueprint application to HHS 
for review and approval 15 months prior to when the State intends to 
begin OEP operations as a State Exchange. The State Exchange Blueprint 
continues to serve as a vehicle for a State to document its progress 
toward implementing its intended Exchange operational model. HHS 
approves a State's Exchange Blueprint Application and subsequently 
provides approval for a State to operate a State Exchange, based upon a 
State meeting the State Exchange implementation requirements noted in 
the Blueprint Application.
    Under the proposed pre-OE verification period requirement, the 
proposed pre-OE verification period would immediately precede the OEP. 
Accordingly, an Exchange would not only need to be responsible for its 
OEP activities but would also need to be responsible for the proposed 
pre-OE verification period activities. We are of the view that a State 
that is in the process of establishing a State Exchange should be 
responsible for its pre-OE verification activities as well as its OEP 
activities, since eligibility determinations made during the pre-OE 
period also would relate to eligibility for enrollment in the following 
plan year. We therefore determined that a State that is in the process 
of establishing a State Exchange should be ready to do so by the 
beginning of the pre-OE verification period, instead of by OEP, as 
currently required. As such, in HHS' State Exchange Blueprint 
application review and State Exchange approval process, we would need 
to account for assessing the readiness of a transitioning State 
Exchange to conduct the proposed pre-OE verification period functions 
for the August 1 timeframe. HHS' existing review and approval timeline 
has been oriented around the first OEP for a transitioning State 
Exchange. This is when a new State Exchange becomes operational (that 
is, ``goes live'') and accordingly, HHS notifies a transitioning State 
Exchange of its decision prior to the OEP start date. HHS' decision is 
based on a 15-month period of time that HHS needs to sufficiently 
assess the readiness of a transitioning State Exchange to operate its 
own Exchange platform and perform the essential functions of an 
Exchange and allow for a sufficient period of time for HHS to then 
remove the transitioning State Exchange and its State Medicaid agency 
from the Federal Exchange platform. Due to the August 1 timeframe 
associated with this new proposal that needs to be included into the 
State Exchange readiness assessment, the overall timeline for HHS' 
review and assessment of State Exchange functionality would need to be 
moved up so that notification to a transitioning State Exchange of HHS' 
decision occurs earlier than August 1, rather than prior to the start 
of the OEP, since the start of the pre-OE verification period would be 
the new date for when an approved transitioning State Exchange first 
becomes operational.
    Accordingly, in conjunction with the proposed addition of Sec.  
155.410(h), we are proposing to modify Sec.  155.106 to

[[Page 67660]]

provide that a State seeking to operate as a State Exchange would be 
required to submit its Blueprint application 15 months before the date 
it proposes to begin its pre-OE verification period, rather than the 
date it proposes to begin its OEP. We are of the view that this rule, 
if finalized, would not materially burden States, as any State offering 
an FFE or SBE-FP that is considering establishing a State Exchange, and 
that has not yet submitted a State Exchange Blueprint application to 
HHS, would have sufficient time after the release of the final rule to 
include the new pre-OE verification period requirements into their 
planning and decision-making leading up to submitting a State Exchange 
Blueprint application and establishing a State Exchange. Building the 
pre-OE verification period in tandem with the initial OEP may require 
some more start-up effort for a State newly establishing a State 
Exchange, in comparison to an initial OEP only, but we are of the view 
that this would be minimal and less burdensome overall than if a State 
were to first establish an OEP as a State Exchange and then 
subsequently build out the pre-OE verification period as a State 
Exchange.
    We seek comment on this proposal.
2. Definitions and General Standards for Eligibility Determination 
(Sec.  155.300)
    We propose a non-substantive edit to update a cross reference in 
Sec.  155.300(c)(2) from Sec.  155.315(f)(4)(ii) through 
155.315(f)(4)(vi). We make this proposal because elsewhere in this rule 
we propose to move the content of Sec.  155.315(f)(4)(ii)--which 
describes an attestation for APTC reconciliation--to Sec.  
155.315(f)(4)(vi). This proposal is intended to ensure that the meaning 
of Sec.  155.300(c)(2) remains the same.
    We seek comment on this proposal.
3. Eligibility Process (Sec.  155.310)
    We propose to add new cross references to Sec.  155.310(f) to 
account for new effective dates proposed in this rule. The proposed 
revisions to Sec.  155.310(f) would require Exchanges to implement 
determinations of a consumer's eligibility for enrollment in a QHP 
through the Exchange, for APTC, and for CSRs, as applicable, in 
accordance with the effective date rules specified in other subsections 
of part 155. Currently, Sec.  155.310(f)(1) requires that Exchanges 
make initial eligibility determinations in accordance with the dates 
specified in Sec. Sec.  155.410(c) and (f) and 155.420(b), and Sec.  
155.310(f)(2) requires that Exchanges make redeterminations in 
accordance with the dates specified in Sec.  155.330(f) and (i), as 
applicable.
    First, we propose to update Sec.  155.310(f)(1), regarding 
effective dates for initial eligibility determinations, so that it also 
cross-references proposed Sec.  155.315(f)(4)(iv). As described in 
detail in section III.A.4.b.iv. of this proposed rule, we propose at 
Sec.  155.315(f)(4)(iv) new effective date rules that would apply to 
certain initial eligibility determinations for consumers who resolve 
DMIs described in proposed Sec.  155.315(f)(4)(ii). This additional 
cross-reference ensures that Sec.  155.310(f)(1) includes a complete 
list of the places within part 155 where effective dates for initial 
eligibility determinations would be specified.
    Second, we propose to update a cross-reference currently at Sec.  
155.310(f)(2), regarding eligibility redeterminations. Specifically, we 
propose to update the current cross-reference from Sec.  155.335(i) to 
Sec.  155.335(b). This is a technical update that is needed because, as 
part of our proposed updates to Sec.  155.335 described in detail in 
section III.A.7. of this proposed rule, the proposed effective dates 
for annual redeterminations would be covered in proposed Sec.  
155.335(b). As a result, this proposed update is needed to ensure that 
the cross-reference in Sec.  155.310(f)(2) remains accurate.
    We seek comment on this proposal.
4. Verification Process Related to Eligibility for Enrollment in a QHP 
Through the Exchange (Sec.  155.315)
a. Verification of Residency
    We are not proposing any changes to the existing regulatory 
requirements in Sec.  155.315(d) related to verification of residency 
for the reasons described further in this section. However, we are 
considering the feasibility of new residency verification requirements 
and are seeking comment on whether the existing requirements to verify 
residency should be updated in the final rule or in future rulemaking 
to reflect advancements in technology and the availability of new data 
sources or alternative verification methods. We acknowledge that 
historically, verifying residency has been challenging for Exchanges 
due to a variety of reasons that we discuss in this section, however, 
we are seeking comment on whether there are ways to overcome these past 
challenges to allow Exchanges to begin to transition from primarily 
accepting an applicant's self-attestation of residency without 
verification, except in limited circumstances where an Exchange has no 
other option.
    Since the establishment of the Exchanges in 2014, the landscape has 
changed significantly, and, due to challenges Exchanges have faced over 
time, we have reevaluated our position that permitting Exchanges to 
accept an applicant's attestation of residency without further 
verification may no longer be appropriate and a risk to Exchange 
program integrity. We hold this view because of the increased number of 
unauthorized enrollments of consumers in Exchange coverage by agents, 
brokers, and web-brokers, achieved in part through inaccurate residency 
attestations. Therefore, we seek comment on how (1) Exchanges can move 
away from primarily accepting self-attestation of residency without 
further electronic or manual verification to an alternative 
verification method or procedure; (2) how Exchanges can potentially 
strengthen requirements to verify residency, including new methods that 
Exchanges might employ in the short and long term to improve program 
integrity; and (3) whether the final rule should require Exchanges to 
adopt such methods so that accepting self-attestation of residency is 
limited to circumstances where there is truly no other option for an 
Exchange to electronically or manually verify residency. We may 
finalize one or more of the approaches discussed in this section rather 
than retaining the existing requirements at Sec.  155.315(d), or 
consider alternative approaches suggested by commenters for future 
rulemaking, if necessary. We acknowledge that any residency 
verification method discussed in this section would require a period of 
implementation that is likely not feasible to complete in time for PY 
2028. Thus, we additionally solicit comment, particularly from State 
Exchanges, on the anticipated time that would be needed to implement 
any such residency verification methods. When providing comments, we 
also welcome robust solutions that take into consideration ongoing 
operational costs for States, the Federal Government, and Exchanges.
    To be eligible for enrollment in a QHP, an applicant or enrollee 
must reside in the State where an Exchange is established per section 
1312(f) of the Affordable Care Act, and Sec.  155.305(a)(3) specifies 
the residency requirements an applicant or enrollee must meet to be 
eligible for enrollment in a QHP. Generally, with some exceptions, an 
applicant or enrollee who is age 21 or over and not living in an 
institution meets the residency requirements if the applicant or 
enrollee (1) is living and intends to reside in the service area of the 
Exchange; or (2) is living and has entered into a job commitment or is

[[Page 67661]]

seeking employment in the service area of the Exchange. An applicant or 
enrollee under age 21 and not living in an institution generally meets 
the residency requirements if they (1) reside in the service area of 
the Exchange; or (2) reside with a parent or caretaker who has met the 
residency standard for the service area of the Exchange. In addition, 
applicants or enrollees are not required to have a fixed address to 
meet the residency requirements; however, they must live in the State 
where they are applying for coverage with the intent to reside in that 
State. This is a critical protection for individuals experiencing 
homelessness or housing instability.
    Section 1411 of the Affordable Care Act does not specify the data 
source or verification method that the Exchanges must use to verify 
residency. Therefore, under section 1411(d) of the Affordable Care Act, 
the Secretary of HHS has broad authority to specify any appropriate 
manner of verification for Exchanges to verify the residency 
requirements so long as it is accurate and appropriate. Generally, as 
outlined in Sec.  155.315(d), if information provided by an applicant 
regarding residency is reasonably compatible with other information 
provided by the individual or in the records of the Exchange, an 
Exchange may either verify information with an electronic data source 
that is sufficiently current and accurate and minimizes administrative 
costs and burdens, or by accepting the applicant or enrollee's 
attestation without further electronic or manual verification. If the 
information provided by the applicant or the enrollee regarding 
residency is not reasonably compatible with other information provided 
by the individual or in the records of the Exchange, the Exchange is 
required to verify information with an electronic data source that is 
sufficiently current and accurate and minimizes administrative costs 
and burdens. If the information provided by the applicant or enrollee 
does not match the information returned via the approved data source, 
then a DMI is created in accordance with Sec.  155.315(f).
    Currently, we have not identified any single data source to verify 
residency for the FFE and SBE-FPs that is current, accurate, and 
minimizes administrative costs and burdens. Using the flexibility 
provided in section 1411 of the Affordable Care Act, we have 
implemented operations for the FFE and SBE-FPs to validate that the 
address provided by an Exchange applicant or enrollee is a real 
address, but it does not validate that the applicant or enrollee 
actually resides at that address. This validation process requires the 
applicant or enrollee to provide a home address on their Exchange 
application. Once the address is provided, the FFE or SBE-FP confirms 
whether the home address is within the service area of the Exchange 
where the applicant or enrollee is applying for coverage. The FFE or 
SBE-FP then attempts to validate the home address to ensure it exists 
by checking United States Postal Service (USPS) records, and the 
applicant or enrollee is prompted to either agree with their provided 
home address or accept a corrected address from USPS records. Address 
validation provides HHS with benefits such as better data quality and 
assurance that mail is delivered to a real address, which reduces 
downstream administrative costs associated with incorrect addresses. 
However, because it does not validate that an applicant lives at a 
specified address and given our ongoing concerns regarding unauthorized 
or potentially fraudulent enrollments, we are of the view that address 
validation is not enough and relying on self-attestation without 
further verification, is a program integrity risk and should only be 
reserved for instances where Exchanges have no other option to verify 
residency.
    Over the years, we have explored options to successfully verify 
residency for applicants or enrollees applying for Exchange coverage 
and identified several challenges. The first challenge relates to the 
lack of available data sources that are current, accurate, and would 
minimize administrative burden. Historically, we have considered data 
sources such as a single database that an Exchange could directly query 
to verify information, similar to how Exchanges connect with Social 
Security Administration (SSA) to verify Social Security Numbers (SSNs). 
We have also considered verification services provided by third-party 
companies that generally use multiple data sources or have their own 
proprietary verification product or method to verify residency. This is 
similar to the optional Verify Current Income Hub (or ``Hub'') service 
Exchanges may use to verify a consumer's projected household income. As 
we noted earlier in this section, there is no data source or other 
verification method mentioned in the statute for the verification of 
residency, although the Secretary of HHS may specify one as needed. 
This means that to implement a stronger process for residency 
verification, we would need to identify a suitable data source (or 
multiple ones), verification service, or another process to 
meaningfully verify a consumer's residency, as well as create a DMI 
process to resolve verifications for any consumers for whom we cannot 
verify residency through either a data source or a verification 
service.
    We are of the view that States and State Exchanges generally are 
better positioned to verify residency for insurance affordability 
programs such as Medicaid and CHIP and for QHP coverage because they 
have access to a variety of State data that could be leveraged to 
verify residency. For example, States and State Exchanges likely have 
access to data sources specific to their State, such as the State 
Directory of New Hires or quarterly wage and unemployment insurance 
data from State workforce agencies (the underlying data that is 
reported in the National Directory of New Hires (NDNH)), which are 
currently unavailable to Exchanges on the Federal platform, in addition 
to casework conducted in their State at the local level.
    Another challenge to verifying residency is that we would need to 
determine which document(s) would be acceptable to successfully verify 
an applicant or enrollee's residency in accordance with Sec.  
155.315(f), when any approved data source could not do so. Certain 
populations may be harder than others to verify through documentation, 
such as consumers living with roommates, consumers who sublease, or 
consumers who move frequently. If we require a new residency 
verification process, and we continue to be unable to electronically 
verify residency for many applicants or enrollees, Exchanges would have 
to establish a DMI process for residency to manually verify residency 
through document submission for many applicants or enrollees. As a 
result, total DMI volumes would increase, and could lead to increasing 
operational costs for Exchanges.
    After exploring the challenges related to implementing residency 
verification, we considered several potential approaches to adjust 
residency verification for applicants or enrollees applying for 
Exchange coverage with APTC and CSRs. The first approach we considered 
was imposing additional residency verification for all Exchange 
consumers. In 2024, we conducted an address matching pilot with 
LexisNexis to determine the feasibility and accuracy of using that 
verification service for residency verification. This pilot was limited 
to Exchanges on the Federal platform. During the pilot, we found that 
data was only available for about half of the pilot population, likely 
due to consumers who move frequently or do not update their addresses 
in a

[[Page 67662]]

timely manner after a move. Based on the pilot and past experience with 
DMIs, we estimate that about half of all Exchange applicants or 
enrollees would receive a DMI and be required to submit documentation 
to verify their residency, due to the lack of data available for 
verifying residency. Ultimately, we determined that the low rate of 
data matching combined with the potential costs of using the LexisNexis 
service did not meet the regulatory standard for using LexisNexis as a 
data source.
    Another approach we considered to verify residency for all Exchange 
applicants was contracting with the IRS, a data broker, or both, to 
develop a Hub service that could verify residency. From our research, 
we determined that, like our pilot with LexisNexis, any of the 
available data brokers or government agencies that could create a Hub 
service to verify residency would likely encounter similar coverage 
rates and result in a large portion of consumers receiving residency 
DMIs.
    A third approach we considered was a risk-based approach to target 
applications with a higher risk of insurance fraud. Based on our own 
experience, residency fraud on the FFE is largely driven by instances 
of residential health care providers, frequently associated with sober 
living facilities, working with unlicensed agents (known as ``body 
brokers'') to direct consumers to misrepresent their State of residence 
so that the provider receives greater compensation from a plan with 
more generous out-of-network benefits. This type of residency fraud 
typically occurs in States where QHP issuers offer more generous out-
of-network benefits, usually in States that are large geographically 
but have a small population. This fraud has been identified when QHP 
issuers have requested QHP rescissions \4\ due to the applicant's or 
enrollee's misrepresentation of their State of residence. We have also 
identified other factors that could signal an application has a higher 
fraud risk including mailing addresses outside of the State in which an 
applicant or enrollee is applying for coverage, or applications in 
States with high rates of fraud. However, we cannot identify 
enrollments resulting from transactions with ``body broker'' agents 
directly and efficiently. We estimate that to be able to adequately 
identify such enrollments, we would need to use a broad sampling 
methodology that casts a very wide net, such as verifying the 
enrollments of entire States to uncover instances of fraudulent 
activity. This would be costly and does not solve the challenges 
Exchanges would still face regarding lack of reliable data sources to 
use in a risk-based verification approach, or the challenges consumers 
might face to secure suitable documentation to prove their residency, 
examples of which are discussed above. Therefore, we concluded that a 
risk-based approach may not be the best approach either, but we welcome 
comment from interested parties, in particular States and State 
Exchanges to share their experiences, if they have tried implementing 
risk-based approaches.
---------------------------------------------------------------------------

    \4\ In accordance with Sec.  147.128.
---------------------------------------------------------------------------

    We are of the view that there may be additional solutions, such as 
leveraging federated identity (ID) verification sources, that can 
reasonably verify a consumer's provided address. Such solutions provide 
Exchanges with a higher degree of assurance as addresses are associated 
with applicants who have verified their identities through standards-
based identity proofing mechanisms. Similar to how other Federal 
agencies use federated ID verification sources to link a claimed 
identity with a real individual, we are of the view that Exchanges 
could leverage such verification methods to verify both identity and 
residency at once and may alleviate many of the challenges Exchanges 
have faced in the past with limited coverage or out-of-date data 
sources. Furthermore, because federated ID verification sources create 
a unique digital identity tied to a specific individual, we are of the 
view that this could reduce potential fraudulent activities and create 
more trust in the self-attestations of residency that applicants with 
verified identities provide on their applications. We are also of the 
view that this verification method would deter bad actors from pursuing 
some insurance fraud schemes. This solution could operate in addition 
to the address validation checks that the FFE and SBE-FPs conduct today 
to ensure that the provided address is standardized and deliverable. We 
are considering requiring Exchanges to use federated ID verification 
and invite comments on its use as a residency verification source.
    Additionally, recognizing that availability of data between States 
and Exchanges is a challenge, we are also interested in exploring the 
idea of mutual data sharing between States and Exchanges, to the extent 
permitted under applicable law, to alleviate the challenges States and 
Exchanges all face regarding residency verification. One avenue to 
achieve such mutual data exchange could be through the Hub, whereby 
States and State Exchanges could make available State data sources 
through the Hub for all requestors, namely the FFE, SBE-FPs, other 
State Exchanges, and State Medicaid Agencies, to access. We are of the 
view that access to more data streams could further mitigate 
unauthorized enrollments and residency fraud. Therefore, we also seek 
comment on whether States are able to share their residency data with 
HHS to facilitate verifications for their State's consumers, as well as 
any barriers that could prevent States from sharing data with HHS, such 
as State law, and whether statutory or regulatory changes in their 
respective State laws would be necessary for them to be able to do so. 
We also invite comment on any data quality standards that we should 
consider to ensure that these data are current, accurate, and minimize 
administrative costs and burdens. Finally, we seek comment from State 
Exchanges and State Medicaid agencies about their experiences with 
verifying residency and any challenges they currently face.
    Based on all the considerations laid out in this section, we are of 
the view that without a more robust residency verification process, the 
risk of applicants or enrollees, and potentially agent, broker, or web-
broker bad actors inappropriately attesting to residing in a State or 
at a particular address to receive Exchange coverage remains. We want 
to emphasize that it is imperative, to the extent practical, that 
Exchanges exercise program integrity measures to discourage potentially 
fraudulent behavior in this area and that is why we are considering 
options for requiring new methods of residency verification, such as by 
using federated ID verification and are seeking comment from interested 
parties on other potential data sources that might be more economical 
for States and/or the Federal Government to procure.
    At this time, we do not propose changes to the current regulatory 
requirements regarding verification of residency as outlined in Sec.  
155.315(d); however, we may instead require new methods of residency 
verification and are exploring options for Exchanges to strengthen 
residency verification using these new methods or through improving 
historically difficult to use data sources. We are using this proposed 
rule to solicit additional ideas for consideration to inform the final 
rule and potentially future policy and regulatory changes. We also seek 
comment on any additional Exchange operational updates that could be 
done in the near term for residency verification that could ultimately

[[Page 67663]]

strengthen program integrity while protecting Exchange risk pools.
    We seek comment on these proposed plans and invite interested 
parties to share their experiences with residency verification, 
including challenges, risk for residency fraud, feasibility of other 
verification approaches or methods such as risk-based approaches, and 
cost/budget impacts.
b. DMIs
    We propose to amend Sec.  155.315(f)(4)(ii) to state that Exchanges 
would generally not be permitted to authorize payment for APTC and CSRs 
for applicants who have DMIs described in Sec.  155.315(c) for 
citizenship status or lawful presence status; Sec.  155.315(d) for 
residency; Sec.  155.320(b) for eligibility for MEC other than through 
an employer sponsored plan; Sec.  155.320(c)(3) for annual household 
income, family size, and eligible noncitizen status; and Sec.  
155.320(d) for enrollment in an eligible employer-sponsored plan and 
eligibility for qualifying coverage in an eligible employer-sponsored 
plan, until such DMIs are adjudicated and applicants are determined 
eligible for APTC and CSRs, as applicable. We also propose in Sec.  
155.315(f)(4)(ii) to exempt those who qualify for an SEP due to a 
change in family size as described under Sec.  155.420(d)(2) from the 
verification requirements described in proposed new Sec.  
155.315(f)(4)(ii), which is described in section III.A.4.c. of this 
proposed rule.
    Additionally, we propose to add Sec.  155.315(f)(4)(iii) to 
establish the requirements related to providing APTC and CSRs during 
inconsistency periods described in Sec.  155.315(f)(4)(ii) created from 
an eligibility redetermination when the information related to the DMIs 
described in Sec.  155.315(f)(4)(ii) was previously verified for the 
plan year. This is described in section III.A.4.d. of this proposed 
rule. We also propose to add new Sec.  155.315(f)(4)(iv) to establish 
that Exchanges would be required to determine eligibility for APTC and 
CSRs on behalf of an applicant following successful verification of 
information as described in proposed new Sec.  155.315(f)(4)(ii), and 
to establish new effective dates of those eligibility determinations or 
redeterminations. We additionally propose to add Sec.  155.315(f)(4)(v) 
specifying that applicants with DMIs other than those described in 
proposed Sec.  155.315(f)(4)(ii) are able to receive APTC and CSRs 
during the inconsistency period if eligible based on the information 
provided on their application. Finally, we propose to amend Sec.  
155.315(f)(4)(i) to remove language around proceeding with all other 
elements of eligibility determination to align with proposed changes to 
Sec.  155.315(f)(4)(ii).
(i) Statutory and Regulatory Overview
(A) Applicable enrollment information
    As described in section II.A. of this proposed rule, under section 
36B(c) of the Code, a taxpayer is only allowed PTC for months that are 
considered coverage months for the taxpayer or other individuals in the 
taxpayer's family. Section 71303(a) of the WFTC legislation added 
section 36B(c)(5) of the Code to provide that, starting in 2028, a 
month is generally not a coverage month for an enrollee in a QHP for 
any month that an Exchange fails to verify specific criteria related to 
the enrollee's eligibility to enroll in a QHP through an Exchange and, 
to the extent relevant, for APTC for the coverage for that month, 
referred to as ``applicable enrollment information''. The specific 
criteria include household income and family size, whether the 
individual is an eligible alien, any health coverage status or 
eligibility for coverage, place of residence, and other information 
determined by the Secretary of the Treasury in consultation with the 
Secretary of HHS. As outlined in the Department of Treasury's Premium 
Tax Credit proposed rule (PTC proposed rule), ``any health coverage 
status or eligibility for coverage'' refers to ``minimum essential 
coverage'' as interpreted by the Department of Treasury (91 FR 65499), 
which aligns with Sec.  155.20 which says the term MEC has the meaning 
given in section 5000A(f) of the Code. Additionally, as explained later 
in this section, the Secretary of the Treasury has proposed regulatory 
changes to include lawful presence status and citizenship in addition 
to the explicitly referenced criteria.
(B) Application to APTC and CSRs
    Section 1411 of the Affordable Care Act outlines the requirements 
for establishing eligibility for QHP \5\ and APTC. We interpret section 
1411(a)(2)(A) of the Affordable Care Act as requiring Exchanges to make 
APTC eligibility determinations consistent with the PTC eligibility 
requirements of 36B of the Code,\6\ including for whether an applicant 
has met the requirements for a month to be considered a coverage month. 
Therefore, we read section 71303(a) of the WFTC legislation as 
requiring verification of specified information before APTC can be 
paid.
---------------------------------------------------------------------------

    \5\ When referencing QHP in this rule, this specifically refers 
to coverage in an individual market QHP offered through an Exchange. 
In accordance with section 1411(a)(1) of the Affordable Care Act, 
Exchange eligibility requirements described in this proposed rule 
would generally not apply to QHPs that are offered outside an 
Exchange.
    \6\ See, for example, in the 2027 Payment Notice proposed rule 
(91 FR 6351).
---------------------------------------------------------------------------

    Additionally, section 1402 of the Affordable Care Act outlines 
requirements for CSRs. Specifically, section 1402(g)(2) states that 
CSRs cannot be allowed for months that are not coverage months for PTCs 
as defined under section 36(B) of the Code. Given this, we have also 
interpreted section 1402(g)(2) of the Affordable Care Act to require 
that an Exchange only provide CSRs for months that qualify as coverage 
months under section 36B of the Code, and therefore we find the new 
eligibility limitations on APTC also apply to Exchange determinations 
of eligibility for CSRs. As discussed later in this rule, there is an 
exception for CSRs for American Indians and Alaska Natives (AI/AN) that 
are not income based.
    Therefore, given the changes outlined under section 36B of the Code 
as amended by section 71303(a) of the WFTC legislation as discussed 
above, we propose that Exchanges can no longer provide APTC and CSRs 
for any month before an Exchange ``verifies, using applicable 
enrollment information that shall be provided or verified by the 
applicant'' the individual's eligibility to enroll in a QHP through an 
Exchange and for APTC. Throughout this rule, ``DMI(s) related to 
applicable enrollment information'' means a DMI for at least one of the 
specific criteria set forth in proposed Sec.  155.315(f)(4)(ii), as 
described in section III.A.4.b.i.A. of this proposed rule. For an 
applicant who is not eligible for the family size SEP waiver as 
described in section III.A.4.c. of this proposed rule, or for an 
eligibility redetermination during the plan year as described in 
section III.A.4.d. of this proposed rule, such a DMI prevents an 
Exchange from providing or increasing any APTC and CSR amounts during 
the inconsistency period. The term therefore excludes DMI for one of 
the specific criteria set forth in proposed Sec.  155.315(f)(4)(ii) 
when the family size SEP waiver applies, as discussed in section 
III.A.4.c. of this proposed rule, as well as during an eligibility 
redetermination during the plan year, as discussed in section 
III.A.4.d.of this proposed rule.
(C) Requirement To Verify
    Section 71303(a) of the WFTC legislation does not specify how 
eligibility for enrollment in a QHP and for APTC and CSRs, as 
applicable, must be ``verif[ied]'' using applicable

[[Page 67664]]

enrollment information. However, section 1411 of the Affordable Care 
Act specifies detailed requirements for verifying eligibility for 
enrollment in a QHP and for APTC and CSRs, which have been codified in 
Sec. Sec.  155.315 and 155.320. Therefore, we read the term ``verify'' 
in section 71303(a) of the WFTC legislation to refer to verification 
procedures under section 1411 of the Affordable Care Act, its 
implementing regulations, and any successor or other applicable 
regulations as may be issued.
    Under section 1411 of the Affordable Care Act, applicants attest to 
information related to eligibility for enrollment in a QHP offered 
through the Exchange and APTC and CSRs, if applicable, on their 
Exchange application, and Exchanges verify the attestations. For most 
eligibility information, Exchanges must verify an applicant's 
attestation by comparing it to a trusted data source. For other 
eligibility information, Exchanges may accept attestation without 
verification, although as discussed in other sections of this proposed 
rule (section III.A.4.a. for residency verification and III.A.5. for 
family size verification) we are considering adopting requirements that 
would further limit instances where verification by self-attestation 
would be permissible, unless there are no available data sources that 
are current, accurate, and minimize administrative costs or burdens, or 
methods to verify the information provided by a consumer. We describe 
the verification process for different eligibility information below.
    Section 1411 of the Affordable Care Act requires that Exchanges 
verify certain information through specific government entities: the 
Commissioner of Social Security and Secretary of Homeland Security for 
citizenship and lawfully present immigration status, and, beginning in 
PY 2027, eligible noncitizen \7\ statuses in section 1411(c)(2), and 
the Secretary of Treasury for household income and family size in 
section 1411(c)(3). Per current Exchange procedures, for citizenship 
and immigration statuses under Sec.  155.315(c), and, beginning in PY 
2027, eligible noncitizen status \8\ and household income under Sec.  
155.320(c)(3), Exchanges are generally required to request information 
from the specified trusted data sources, as applicable, to verify the 
applicant's attestation. In the case of family size, current 
requirements in Sec.  155.320(c)(3)(i) state that Exchanges are 
generally permitted to accept the applicant's attestation without 
further verification when family size cannot be verified through the 
IRS.\9\ As described further in section III.A.5. of this proposed rule, 
we are interested in comments related to the future state of family 
size verification.
---------------------------------------------------------------------------

    \7\ See 91 FR 29601-29602.
    \8\ See 91 FR 29601-29602.
    \9\ The verification requirements for eligible noncitizen 
status, household income, and family size apply only to applicants 
applying for financial assistance.
---------------------------------------------------------------------------

    For other criteria, such as residency, enrollment in an eligible 
employer-sponsored plan and eligibility for qualifying coverage in an 
eligible employer-sponsored plan, and eligibility for MEC other than 
through an eligible employer-sponsored plan, the Affordable Care Act 
does not prescribe specific data sources to use, and instead section 
1411(d) of the Affordable Care Act gives the Secretary of HHS the 
flexibility to determine the verification process in any manner the 
secretary determines appropriate.\10\ For residency under Sec.  
155.315(d), Exchanges generally may accept attestation or may use any 
electronic data sources that have been approved by HHS based on 
evidence that they are sufficiently available, current, accurate, and 
minimize administrative costs and burden. Currently, the FFE, SBE-FPs, 
and some State Exchanges, accept attestation, while other State 
Exchanges utilize data sources to request information and attempt to 
verify attestation. However, we are interested in exploring potential 
ways for Exchanges to move away from primarily accepting self-
attestation without further verification to verify residency through a 
trusted data source or documentation in the near future. Further 
information is available in section III.A.4.a. of this proposed rule.
---------------------------------------------------------------------------

    \10\ The verification requirements for enrollment in an eligible 
employer-sponsored plan and eligibility for qualifying coverage in 
an eligible employer-sponsored plan, and eligibility for MEC other 
than through an eligible employer-sponsored plan apply only to 
applicants applying for financial assistance.
---------------------------------------------------------------------------

    For enrollment in an eligible employer-sponsored plan and 
eligibility for qualifying coverage in an eligible employer-sponsored 
plan, under Sec.  155.320(d), Exchanges must use: (1) any electronic 
data sources that HHS has approved as being sufficiently current, 
accurate, and minimizing administrative burden; (2) any electronic data 
sources that provide data on coverage based on Federal employment, and 
(3) any data available for the Small Business Health Options Program 
(SHOP) in the applicable State. HHS has not approved any data sources 
as being sufficiently current, accurate, and minimizing administrative 
burden. Therefore, Exchanges are only required to verify eligibility 
and enrollment in employer-sponsored coverage electronically with the 
Office of Personnel Management (OPM) and the applicable SHOP. If those 
data sources indicate that the consumer is enrolled in eligible 
employer-sponsored plan or eligible for qualifying coverage in an 
eligible employer-sponsored plan, then the consumer receives a DMI and 
is required to submit documentation to verify their attested 
information. Finally, if an Exchange does not expect to obtain data 
from at least one electronic data source that has been approved by HHS 
to be sufficiently current, accurate, and minimize administrative 
burden, it may follow an alternative process described in paragraph 
(d)(4)(i). Specifically, an Exchange may use a risk-based approach to 
verify whether an applicant is enrolled in an eligible employer-
sponsored plan or eligible for qualifying coverage in an eligible 
employer-sponsored plan. If an Exchange's assessment of risk shows a 
low risk for inappropriate payment of APTC or CSRs, an Exchange is 
permitted to accept an applicant's attestation without further 
verification.
    In the HHS Notice of Benefit and Payment Parameters for 2023 final 
rule (2023 Payment Notice) (87 FR 27208, 27270 and 27271), we provided 
guidance that if Exchanges do not have access to an approved data 
source that provides accurate and up-to-date information regarding 
eligibility for or enrollment in coverage offered through an employer 
and determined through research that the risk of improper eligibility 
determinations for APTC and CSRs is low, that Exchanges are permitted 
to accept a consumer's attestation without any further verification. 
This is the verification procedure that the FFE and SBE-FPs adopted as 
a risk-based approach since the risk for inappropriate APTC and CSRs 
was deemed to be low, as discussed in the 2023 Payment Notice. Because 
we are still of the view that the risk is still low of improper 
eligibility determinations for APTC and CSRs resulting from 
attestations regarding eligibility for an employer-sponsored plan and 
eligibility for qualifying coverage in an eligible employer-sponsored 
plan, we do not propose any changes to the process for verifying such 
information. Accordingly, Exchanges are permitted to continue following 
whatever approved risk-based approach they currently are approved to 
use by HHS.
    Finally, under Sec.  155.320(b), for verification related to 
eligibility for MEC other than through an eligible employer-

[[Page 67665]]

sponsored plan, such as Medicaid and Medicare, Exchanges use electronic 
data sources to verify applicants' attestations.
    Regardless of the type of eligibility information, section 
1411(e)(3) and (e)(4)(B)(i) of the Affordable Care Act require that, 
when application information is required to be verified through a 
trusted data source but cannot be, Exchanges must set a DMI and provide 
applicants 90 or 95 days (depending on the type of DMI) to provide 
documentation to resolve the DMI. Exchanges must determine eligibility 
for QHP coverage and APTC and CSRs based on attested information on the 
application and provide such coverage and APTC or CSRs, as applicable, 
during the inconsistency period. Accordingly, in the March 27, 2012, 
Exchange Establishment Rule (77 FR 18310), we finalized that Exchanges 
must determine eligibility for APTC and CSRs for applicants based on 
attested information on the application during an inconsistency period, 
which was done through adding Sec.  155.315(f)(4). Specifically, Sec.  
155.315(f)(4)(i) and (ii) currently require Exchanges to proceed with 
all other elements of eligibility determination using the applicant's 
attestation during an inconsistency period and grant QHP eligibility if 
otherwise qualified, provided that the applicant attests that they 
understand their APTC is subject to reconciliation when they file their 
Federal income taxes. This means that, currently, consumers who receive 
DMI(s) are deemed eligible for QHP coverage through Exchanges and, if 
applicable, APTC and CSRs, based on the information on their 
application while those DMI(s) remain open (as long as the attestation 
is provided if required).
    As set forth in Sec.  155.315(f)(2)(ii), Exchanges can resolve a 
DMI either when the consumer submits sufficient documentation to verify 
their attested information or when Exchanges receive updated 
information from data sources that verifies the attested information. 
Once a DMI is resolved, the applicant's eligibility is verified, and 
they can continue receiving QHP coverage through the Exchange and APTC 
and CSRs as applicable. However, as noted in Sec.  155.315(f)(5), if an 
Exchange is unable to resolve a DMI within the 90/95-day inconsistency 
period, an Exchange redetermines eligibility based on information from 
data sources, typically resulting in a loss of enrollment in QHP 
coverage or a loss or decrease in APTC and CSRs. In cases of an 
application with multiple applicants, eligibility is determined for 
each applicant who has a DMI, with the exception of DMI types that 
apply at the household level, such as annual household income DMIs, in 
which case the DMI applies to the entire household. Applicants who 
update their application during the coverage year and receive an 
eligibility redetermination follow the same process as outlined above.
    While this is the current process, as discussed above, we read 
section 71303(a) of the WFTC legislation to generally prohibit 
Exchanges from providing APTC and CSRs for any month before it has 
verified, using certain specified information, a consumer's eligibility 
for enrollment in a QHP and for APTC and CSRs, as applicable, for those 
months. Also as previously mentioned, we read that the requirement to 
``verif[y]'' such information to mean to verify in accordance with 
section 1411 of the Affordable Care Act and implementing regulations. 
For citizenship, lawfully present immigration status, eligible 
noncitizen status, and annual household income, Exchanges must verify 
an applicant's attestation through a trusted data source, and if the 
trusted data source cannot verify the attestation, set a DMI and 
provide an applicant with a 90/95-day inconsistency period to provide 
documents to resolve their DMI. Therefore, we read section 71303(a) of 
the WFTC legislation to prohibit payment of APTC and CSRs for any month 
before an Exchange verifies an applicant's attestation regarding 
citizenship, lawfully present immigration status, eligible noncitizen 
status,\11\ and annual household income through a trusted data source 
or, if the applicant's attestation cannot be verified through a trusted 
data source, until the applicant provides documents to resolve their 
DMI and they have been determined eligible for APTC and CSRs.
---------------------------------------------------------------------------

    \11\ PTC proposed rule (91 FR 65498).
---------------------------------------------------------------------------

    Regarding verification of family size, Exchanges must submit family 
size information to the Secretary of Treasury for verification. 
However, per Sec.  155.320(c)(3)(i)(A), if the Secretary of Treasury 
cannot verify family size, Exchanges may accept an applicant's 
attestation of family size if the consumer attests that a change in 
circumstance has occurred or is likely to occur, as long as the data 
provided by the applicant is reasonably compatible with other 
information provided about their family. More information regarding 
family size verification can be found in section III.A.4.c. of this 
proposed rule.
    In contrast, for verification of residency, enrollment in an 
eligible employer-sponsored plan and eligibility for qualifying 
coverage in an eligible employer-sponsored plan, and eligibility for 
MEC other than through an eligible employer-sponsored plan, section 
1411(d) of the Affordable Care Act does not specify specific data 
sources to use. As such, and as explained above, HHS regulations 
sometimes require attestations about such information to be verified 
through a trusted data source, or, if the trusted data source cannot 
verify the information, through documentation, and other times permit 
Exchanges to verify such information through attestation.
    Therefore, we read section 71303(a) of the WFTC legislation to 
prohibit payment of APTC and CSRs for any month before an Exchange 
verifies residency, enrollment in an eligible employer-sponsored plan 
and eligibility for qualifying coverage in an eligible employer-
sponsored plan, eligibility for MEC other than through an eligible 
employer-sponsored plan, and family size--however verification is 
required under section 1411 of the Affordable Care Act, its 
implementing regulations, and any successor or other applicable 
regulations as may be issued, and we are exploring further updates to 
residency and family size verification as outlined further in sections 
III.A.4.a. and III.A.4.c. of this proposed rule. Additionally, we 
emphasize that some State Exchanges may have data available to them 
that are sufficiently current, accurate, minimizes administrative 
burden, and approved by the Secretary of HHS for usage and therefore 
may already be setting DMIs for criteria that the Federal Exchange 
currently does not, and this proposed rule does not limit State 
Exchanges from setting DMIs in those instances. In summary, when 
attestations about such information must be verified through a trusted 
data source or documentation, we read section 71303(a) of the WFTC 
legislation to prohibit payment of APTC and CSRs until such 
verification is complete.
    As such, we are proposing to amend Sec.  155.315(f) to reflect the 
new requirement of section 71303(a) of the WFTC legislation. 
Specifically, we propose in Sec.  155.315(f)(4)(ii) that if an 
applicant receives a DMI related to the applicable enrollment 
information, Exchanges would be prohibited from providing APTC and CSRs 
until those DMIs are adjudicated and the Exchange determines that the 
applicant is eligible for enrollment in a QHP and for APTC and CSRs, as 
applicable. In contrast, for a DMI not related to applicable enrollment 
information, or if a family size SEP waiver applies, as discussed in 
section III.A.4.c. of this proposed rule, and during eligibility 
redeterminations

[[Page 67666]]

during the plan year, as discussed in section III.A.4.d. of this 
proposed rule, Exchanges would be required to continue payment APTC and 
CSRs, if otherwise eligible, during an inconsistency period. 
Specifically, this includes DMIs for AI/AN status.
    We acknowledge that section 71303(a) of the WFTC legislation could 
be read to allow Exchanges to always treat an applicant's information 
as ``verified'' such that a month can be considered a ``coverage 
month'' if the applicant affirms (that is, attests to) the required 
information. As previously mentioned, section 71303(a) of the WFTC 
legislation added section 36B(c)(5)(A) of the Code, effective beginning 
in 2028, and section 36B(c)(5)(A) states that a coverage month cannot 
include any month before an Exchange ``verifies, using applicable 
enrollment information that shall be provided or verified by the 
applicant, such individual's eligibility'' to enroll in a QHP or 
receive APTC. (Emphasis added). Section 71303(a) of the WFTC 
legislation that added section 36B(c)(5)(B) of the Code, effective 
beginning in 2028, and section 36B(c)(5)(B) provides that ``applicable 
enrollment information shall include affirmation'' of the specified 
criteria. One could read these provisions together as permitting 
Exchanges to verify an applicant's eligibility using only the 
applicant's provided affirmation (or attestation) of the enumerated 
eligibility criteria, rather than using an external data source or 
submitted documentation. However, as explored further below, we are of 
the view that this reading of section 71303(a) of the WFTC legislation 
is implausible.
    As discussed previously in this proposed rule, given that the term 
``verifies'' is ambiguous in section 71303 of the WFTC legislation, the 
statutory language is best read to mean that an Exchange verifies the 
specified criteria in accordance with the verification procedures 
articulated in section 1411 of the Affordable Care Act, its 
implementing regulations, and any successor or other applicable 
regulations as may be issued.\12\ These successor applicable 
regulations include potential future updates to perform further 
verification of residency beyond accepting attestation, as described in 
section III.A.4.a. of this proposed rule. This is supported by the 
language in section 71303(a) of the WFTC legislation stating that an 
Exchange must verify eligibility for enrollment in a QHP and for APTC 
and CSRs, as applicable, using the specified information ``provided'' 
or ``verified'' by the applicant. We read that the terms ``provided'' 
and ``verified'' to refer to the verification procedures under section 
1411 of the Affordable Care Act and implementing regulations which, as 
explained previously in this proposed rule, allow Exchanges to verify 
some eligibility criteria using an attestation provided by the 
applicant and which require further verification from a trusted data 
source or documentation in the case of other eligibility criteria. 
Given that the WFTC legislation does not prescribe any new specific 
methods of verification, we read it as permitting existing verification 
processes to continue, except that generally a month may not be a 
coverage month, and therefore no APTC or CSRs can be provided, until 
verification under section 1411 of the Affordable Care Act, its 
implementing regulations, and any successor or other applicable 
regulations as may be issued, is complete. As previously stated, we are 
requesting comments on whether updates should be made to the 
verification of residency as defined under Sec.  155.315(d), which is 
discussed further in section III.A.4.a. of this proposed rule, and the 
verification of family size as defined under Sec.  155.320(c)(3), which 
is discussed further in section III.A.5. of this proposed rule.
---------------------------------------------------------------------------

    \12\ We note that neither the current verification processes 
conducted by Exchanges, nor the proposed verification processes that 
would be conducted by Exchanges if the proposals in this rule were 
finalized, would in any way change the obligations of agents, 
brokers, and web-brokers to comply with the FFE Standards of Conduct 
at 45 CFR 155.220(j), including the obligation to provide the FFEs 
with correct information, and document that eligibility application 
information has been reviewed by and confirmed to be accurate by the 
consumer or their authorized representative prior to submission to 
the Exchange. See 45 CFR 155.220(j)(2)(ii). These obligations extend 
to agents, brokers, and web-brokers assisting consumers on the SBE-
FPs. See 45 CFR 155.220(l).
---------------------------------------------------------------------------

    Additionally, we are of the view that reading section 71303(a) of 
the WFTC legislation to permit Exchanges to treat all attested 
information as verified would, effectively, render the changes under 
section 71303(a) meaningless as, under current rules, that reading 
would result in a month likely being considered a coverage month based 
on just an applicant's attestation of eligibility criteria. Therefore, 
we are of the view that the intention of the WFTC legislation is to 
rely on existing verification procedures in section 1411 of the 
Affordable Care Act, its implementing regulations, and any successor or 
other applicable regulations as may be issued for purposes of 
verification under section 71303 of the WFTC legislation.
    In summary, due to the new requirements in section 71303 of the 
WFTC legislation, we are of the view that APTC and CSRs cannot be 
provided to consumers when eligibility for enrollment in a QHP and for 
APTC and CSRs, as applicable, have not been verified using the 
specified criteria in accordance with section 1411 of the Affordable 
Care Act and implementing regulations--which allows certain information 
to be verified through attestation and which requires certain other 
information to be verified by either a trusted data source or 
documentation provided by the applicant during an inconsistency period. 
Therefore, we have determined that significant changes to the 
verification procedures in Sec.  155.315(f)(4) related to providing 
APTC and CSRs during an inconsistency period are required. These 
changes are described below.
(ii) APTC and CSRs During Certain Inconsistency Periods (Sec.  
155.315(f)(4)(ii))
    As described in section II.A. of this proposed rule, section 
71303(a) of the WFTC legislation describes the specific criteria that 
must be verified before a month is considered a coverage month. These 
criteria are household income and family size; whether an individual is 
an eligible alien; any health coverage status or eligibility for 
coverage; place of residence; and other information as may be 
determined by the Secretary of Treasury, in consultation with the 
Secretary of HHS, as necessary to the verification described in section 
36B(c)(5)(A) of the Code, as added by section 71303(a) of the WFTC 
legislation. Per the PTC proposed rule (91 FR 65498), the Secretary of 
the Treasury proposes to include citizenship and lawful presence status 
as criteria under section 36B(c)(5)(B)(v) of the Code that must be 
verified before a month can be a coverage month. Therefore, in light of 
the Secretary of Treasury's PTC proposed rule, and our interpretation 
of section 1411(a)(2)(A) of the Affordable Care Act that Exchanges must 
make APTC eligibility determinations consistent with the PTC 
eligibility requirements of section 36B of the Code, we are proposing 
to require citizenship and lawful presence be verified before Exchanges 
can provide APTC or CSRs.
    Accordingly, when an applicant receives a DMI for annual household 
income and family size, citizenship, lawful presence status, eligible 
noncitizen status, residency, eligibility for MEC other than through an 
employer-sponsored plan, or eligibility

[[Page 67667]]

for or enrollment in employer-sponsored coverage,\13\ we propose that 
any DMI generated for these applicable enrollment information would 
need to be adjudicated by an Exchange (that is, the applicant's 
eligibility for APTC and CSRs must be verified) before APTC or CSRs can 
be paid for the applicant for any months, including prior months as 
described later in section III.A.4.b.iv. of this proposed rule. We note 
that although lawful presence status is included in these criteria and 
would be required to be verified before APTC and CSRs are provided, we 
do not expect this would have a functional impact on Exchanges. 
Beginning in PY 2027, only consumers who have eligible noncitizen 
status as defined in Sec.  155.20 are eligible for APTC and CSRs. 
Eligible noncitizens are a subset of lawfully present noncitizens, 
specifically individuals who have been lawfully admitted for permanent 
residence (sometimes referred to as a ``lawful permanent resident'' or 
``green card holder''), those who have been granted the status of Cuban 
and Haitian entrant as defined in section 501(e) of the Refugee 
Education Assistance Act of 1980, and those who are lawfully residing 
in the United States in accordance with the Compacts of Free 
Association (COFA) as defined at 8 U.S.C. 1612(b)(2)(G) (sometimes 
referred to as a ``COFA migrant''). We anticipate that, given Exchange 
operations, the functional impact of the proposed requirement to verify 
lawful presence status would be handled through the verification of 
eligible noncitizen status per Sec.  155.320(c)(3)(ix).
---------------------------------------------------------------------------

    \13\ Consistent with the Secretary of Treasury in the PTC 
proposed rule (91 FR 65499), we interpret ``any health coverage 
status or eligibility for coverage'' to refer to ``minimum essential 
coverage'' as described in Sec.  155.20.
---------------------------------------------------------------------------

    Notwithstanding the above, as mentioned earlier in this section, 
section 71303(a) of the WFTC legislation provides for an exception to 
the verification requirements described in section 36B(c)(5)(A) of the 
Code. Specifically, section 71303(a) of the WFTC legislation adds 
section 36B(c)(5)(E) of the Code, which allows the Secretary of 
Treasury to waive the verification requirements (for coverage month 
purposes) for applicants who enroll during an SEP based on a change in 
the applicant's family size, including current enrollees who are 
eligible to enroll due to a family size SEP. As a result, and 
consistent with the PTC proposed rule (91 FR 65494), we are proposing 
in Sec.  155.315(f)(4)(ii) to require Exchanges to provide this 
exception for SEPs where an applicant, or a member of their household, 
has a qualifying life event related to a change in family size, such as 
birth or adoption of a child. Further information about this proposal 
is provided in section III.A.4.c. of this proposed rule and in the PTC 
proposed rule (91 FR 65499). In addition, as discussed in section 
III.A.4.d. of this proposed rule, we are also proposing modified 
procedures when an eligibility redetermination results in DMIs related 
to applicable enrollment information that was previously verified for 
the plan year.
    Additionally, for the reasons described in section III.A.4.b.i. of 
this proposed rule, we are not proposing to amend the Exchanges 
verification requirements except to prohibit (in most situations) 
payment of APTC and CSRs before eligibility for enrollment in a QHP and 
for APTC and CSRs, as applicable, have been verified in accordance with 
section 1411 of the Affordable Care Act, its implementing regulations, 
and any successor or other applicable regulations as may be issued is 
complete. We discuss below in more detail the current process for 
verifying enrollment in an eligible employer-sponsored plan and 
eligibility for qualifying coverage in an eligible employer-sponsored 
plan. Additionally, we are requesting comments on whether updates 
should be made to the verification of residency as defined under Sec.  
155.315(d) and discussed further in section III.A.4.a. of this proposed 
rule and the verification of family size as defined under Sec.  
155.320(c)(3) and discussed further in section III.A.5. of this 
proposed rule.
    In addition, while section 71303 of the WFTC legislation does not 
specifically mention CSRs, we are also of the view that Exchanges are 
required to withhold CSRs during the specified inconsistency periods. 
As mentioned earlier in this section, section 1402(g)(2) of the 
Affordable Care Act, which is codified in Sec.  155.305(g), outlines 
that applicants are only eligible for CSRs for months in which they are 
also eligible for APTC and meet all other CSR eligibility criteria. 
Therefore, we propose to require Exchanges to withhold CSRs prior to an 
Exchange having verified eligibility for enrollment in a QHP and for 
APTC and CSRs using the applicable information required under section 
36B(c)(5) of the Code.
    One important clarification is that the special cost-sharing rule 
specific to AI/AN applicants specifically for items and services 
provided through the Indian Health Service, an Indian Tribe, Tribal 
Organization, an Urban Indian Organization, or through referrals under 
contracted health services (hereinafter ``Indian health providers'') 
under section 1402(d)(2) of the Affordable Care Act, and implemented in 
Sec.  155.350(b), is not impacted by new requirements in section 71303 
of the WFTC legislation because it is not conditioned on being eligible 
for APTC. Under Sec.  155.350(b), Exchanges must determine an AI/AN 
applicant eligible for special cost-sharing described in section 
1402(d)(2) of the Affordable Care Act without requiring them to request 
an eligibility determination for insurance affordability programs in 
accordance with Sec.  155.310(b). To clarify, an individual who is a 
member of a Federally recognized tribe or is an ANCSA Corporation 
shareholder may be subject to cost sharing under the special cost-
sharing rule even if they do not apply for any financial assistance (as 
in, APTC and CSRs) when they apply for QHP coverage through an Exchange 
or if they apply but are determined ineligible.
    In contrast, income-based CSRs that AI/AN applicants may receive 
are tied to APTC eligibility, as described in Sec.  155.350(a), and 
therefore would be subject to the requirements proposed in this 
section. As an example, if a consumer who is a member of a Federally 
recognized tribe applies for QHP coverage through an Exchange with 
financial assistance, the Exchange would be required to follow the 
verification processes outlined in section 1411 of the Affordable Care 
Act and implementing regulations. In cases where they receive a DMI 
related to the applicable enrollment information, they would be able to 
receive cost sharing under the special cost sharing rule for AI/AN 
individuals for items and services provided through Indian healthcare 
providers, as previously described, but would not receive income-based 
CSRs until all DMIs related to the applicable enrollment information 
are adjudicated and they have been determined eligible for APTC and 
CSRs.
    As an additional point of clarification, while we propose that 
Exchanges would be prohibited from determining an applicant eligible 
for APTC and CSRs during an inconsistency period for DMIs related to 
the applicable enrollment information, we are not proposing to prohibit 
Exchanges from determining eligibility for enrollment in a QHP during 
the same period, even if the DMI related to the applicable enrollment 
information is related to eligibility for enrollment in a QHP (such as 
citizenship or lawful presence status). Section 71303(a) of the WFTC 
legislation states that an individual's eligibility to enroll in a QHP 
and for APTC must be verified using applicable

[[Page 67668]]

enrollment information for a month to be considered a ``coverage 
month'' under section 36B of the Code. A coverage month is required for 
APTC and CSRs to be paid but has no bearing on an applicant's 
eligibility for enrollment in a QHP. Additionally, section 36B(c)(5)(D) 
of the Code, as added by section 71303(a) of the WFTC legislation, 
explicitly states that applicants cannot be treated as ineligible to 
enroll in a QHP through an Exchange solely for failing to meet the 
requirements to verify applicable enrollment information as required by 
section 36B(c)(5)(A) and (B) of the Code.
    Therefore, we propose that an applicant would be required to be 
determined eligible for enrollment in, and may enroll in, a QHP during 
any period in which the applicant has any DMI, including when the DMI 
relates to information necessary to determine eligibility for a QHP, 
such as citizenship or lawful presence status, if otherwise eligible. 
Accordingly, we only propose a minor conforming edit to Sec.  
155.315(f)(4)(i), which would still state that Exchanges must provide 
eligibility for a QHP if an applicant is otherwise eligible during an 
inconsistency period. We note that an applicant who enrolls in a QHP 
during an inconsistency period related to QHP eligibility information 
must verify such eligibility by the end of their 90-day inconsistency 
period. If they fail to do so, their QHP enrollment through the 
Exchange would be terminated.\14\
---------------------------------------------------------------------------

    \14\ However, failure to meet eligibility requirements for 
enrollment through the Exchange generally is not a basis for a 
health insurance issuer to terminate health insurance coverage under 
the guaranteed renewability requirements of section 2703 of the 
Public Health Service Act and 45 CFR 147.106. Accordingly, an 
individual whose Exchange enrollment is terminated for failure to 
meet Exchange eligibility criteria generally would have a right to 
renew or continue in force such coverage outside the Exchange.
---------------------------------------------------------------------------

    In summary, we propose to amend Sec.  155.315(f)(4)(ii) to state 
that Exchanges cannot provide APTC and CSRs based on attested 
information on the application when an applicant has a DMI related to 
the applicable enrollment information.
(iii) Eligibility Redeterminations During the Plan Year (Sec.  
155.315(f)(4)(iii))
    As previously stated, we propose to amend Sec.  155.315(f)(4)(ii), 
which would prohibit Exchanges from providing APTC and CSRs based on 
application information during inconsistency periods for DMIs related 
to the applicable enrollment information. Exchanges would, therefore, 
be prohibited from providing APTC and CSRs during inconsistency periods 
as they currently do, including for the entire application household in 
cases of household-level DMIs such as those related to annual income 
and family size. However, for applicants who submit an application and 
receive new DMIs after they had previously verified all of the 
eligibility criteria specified in proposed Sec.  155.315(f)(4)(ii) for 
the current plan year, we propose to add Sec.  155.315(f)(4)(iii) to 
permit Exchanges to provide APTC and CSRs during an inconsistency 
period. This is discussed in detail in section III.A.4.d. of this 
proposed rule.
(iv) Resolution of DMIs (Sec.  155.315(f)(4)(iv))
    We also propose to add new Sec.  155.315(f)(4)(iv) to establish 
that Exchanges would be required to determine eligibility for APTC and 
CSRs on behalf of an applicant following a successful verification of 
the information described in Sec.  155.315(f)(4)(ii) and to provide 
effective dates for the eligibility determination. Specifically, these 
proposed effective dates rules would apply to determinations and 
redeterminations in two circumstances. First, they would apply to 
determinations resulting from resolution of DMIs related to applicable 
enrollment information. Second, they would apply to redeterminations 
resulting from an applicant resolving all DMIs when the applicant would 
qualify for a greater amount of APTC than they were receiving during 
their inconsistency period upon DMI resolution--that is, DMIs described 
in proposed Sec.  155.315(f)(4)(iii)(A). These rules would apply to the 
DMIs described in Sec.  155.315(f)(4)(ii) and (iii)(A) because 
resolution of these DMIs would generally result in changes to a 
consumer's APTC and CSR eligibility. In contrast, when a DMI described 
in Sec.  155.315(f)(4)(iii)(B) is resolved, such resolution would 
instead confirm the consumer's eligibility for the APTC and CSRs, as 
applicable, that they were already authorized to receive during their 
inconsistency period based on their attestation, and the amount of APTC 
and CSRs would remain the same.
    We propose in Sec.  155.315(f)(4)(iv)(A) that, if a consumer is 
already enrolled in a QHP when such DMIs are resolved by an Exchange, 
an Exchange would generally be required to implement the resulting APTC 
and CSR eligibility determination effective the first day of the first 
month in which all the following criteria are met: (1) an Exchange 
determined all eligibility criteria described in proposed Sec.  
155.315(f)(4)(ii) to be verified for that month, (2) the consumer was 
enrolled in a QHP on the first day of that month, and (3) the 
consumer's DMI was generated prior to the first of that month. This 
would allow APTC and CSRs to be paid prospectively, as well as 
retroactively, subject to the conditions described. We propose one 
exception to these rules, for cases where these rules would otherwise 
result in Exchanges being required to provide APTC for months in the 
prior coverage year. In these cases, we propose that Exchanges would 
not provide APTC for months in the prior coverage year, and consumers 
would instead claim any PTC for which they were eligible on their 
Federal income tax return.
    This proposal would implement section 36B(c)(5)(C) of the Code, 
which was added by section 71303(a) of the WFTC legislation. Section 
36B(c)(5)(C) of the Code provides that a month that begins before 
completion of the verification prescribed by section 36B(c)(5)(A) of 
the Code must be treated as a coverage month for an individual if the 
Exchange verifies (using applicable enrollment information) that the 
individual is eligible to enroll in a QHP and for APTC. This provision 
effectively requires an Exchange to provide APTC and CSRs, as 
applicable, retroactively after verification of applicable enrollment 
information.\15\
---------------------------------------------------------------------------

    \15\ As discussed throughout this proposed rule, we interpret 
section 1411(a)(2) of the Affordable Care Act to require Exchanges 
to make APTC eligibility determinations consistent with the PTC 
eligibility requirements of section 36B of the Code, including 
whether an applicant has met the requirements for a month to be 
considered a coverage month. Also as previously discussed, we have 
also interpreted section 1402(g)(2) of the Affordable Care Act to 
require that an Exchange only provide CSRs for months that qualify 
as coverage months under section 36B of the Code.
---------------------------------------------------------------------------

    Section 36B(c)(2)(A)(i) of the Code requires an individual to be 
enrolled in a QHP as of the first of a month before the month can be a 
coverage month. Section 36B(c)(5)(A) of the Code provides, in relevant 
part, that a coverage month does not include any month that begins 
before the Exchange verifies an individual's eligibility to enroll in a 
QHP and for APTC. Accordingly, we propose that the retroactive period 
would go no further than the first of the month in which all the 
following conditions are met: an Exchange verified all eligibility 
criteria described in proposed Sec.  155.315(f)(4)(ii), the consumer 
was enrolled in a QHP on the first day of that month, and the 
consumer's DMI was generated prior to the first of that month.
    First, at Sec.  155.315(f)(4)(iv)(A)(1), we propose that the 
retroactive period

[[Page 67669]]

would not extend beyond the first day of the first month for which the 
Exchange verified all eligibility criteria described in proposed Sec.  
155.315(f)(4)(ii). This implements the requirement in section 
36B(c)(5)(C) of the Code that a month beginning prior to verification 
only be considered a coverage month if the Exchange verifies the 
consumer's eligibility ``for such month.''
    Under this proposal, Exchanges would be required to consider annual 
household income to be verified for months prior to the resolution of 
an annual household income DMI. This is because when verifying annual 
household income, Exchanges are verifying an individual's projected 
household income for the entire coverage year, and a successful 
verification therefore indicates that the individual's projection is 
considered verified for all months of the year unless and until a 
change is reported.
    Exchanges would also be required to consider U.S. citizenship to be 
verified for months prior to the resolution of a U.S. citizenship DMI, 
if the consumer submits documents indicating that they are a U.S. 
citizen by birth, or that they are a naturalized citizen whose 
naturalization occurred prior to when they provided their attestation 
of U.S. citizenship to the Exchange. However, if an individual attests 
on their application that they are a U.S. citizen, receives a DMI, and 
subsequently submits documents that indicate that they became 
naturalized in a month following such attestation, then the Exchange 
would only be required to consider the individual's citizenship 
verified for the months that the submitted documents indicated that the 
individual was a U.S. citizen.
    Similarly, if an individual attests to lawful presence or eligible 
noncitizen status, receives a DMI, and subsequently submits documents 
that indicate that they gained their lawfully present or eligible 
noncitizen status in a month following such attestation, then the 
Exchange would only be required to consider the individual's lawful 
presence or eligible noncitizen status verified for the months that the 
submitted documents indicated that the individual was lawfully present 
or an eligible noncitizen. If the individual submitted documents 
demonstrating that they gained their lawfully present or eligible 
noncitizen status in a month prior to their attestation, then the 
Exchange would be required to consider lawful presence and eligible 
noncitizen status, as applicable, to be verified for months prior to 
the resolution of the DMI.
    Finally, if an individual attests that they are not eligible for 
MEC other than through an eligible employer-sponsored plan, receives a 
DMI, and subsequently submits documents that indicate that they ceased 
to be eligible for or enrolled in their other MEC in a month following 
such attestation, then the Exchange would only consider the 
individual's lack of eligibility for or enrollment in other MEC 
verified for the months the submitted documents indicated that the 
individual was not eligible for or enrolled in other MEC. If the 
individual submitted documents demonstrating that they were ineligible 
for or not enrolled in other MEC in a month prior to their attestation, 
then the Exchange would be required to consider this criterion verified 
for any applicable prior months.
    Exchanges would be required to communicate to consumers regarding 
whether past months were successfully verified, and the impact of this 
verification outcome on the Exchange's determination of the consumer's 
APTC and CSR eligibility, via the notification required by Sec.  
155.310(g). We note that this notification would be required by Sec.  
155.515(a)(2) to include information about appeal rights. Existing 
regulations at Sec.  155.505(b)(1) specify that applicants and 
enrollees have the right to appeal an Exchange's eligibility 
determinations, and we interpret this existing requirement to extend to 
eligibility determinations made on the basis of an Exchange's 
assessment regarding whether eligibility criteria were successfully 
verified for months prior to verification.
    We acknowledge that Exchanges would need to make case-by-case 
determinations to determine whether each eligibility criterion can be 
considered verified for months occurring prior to verification. We 
request comment from State Exchanges regarding the feasibility of 
parsing whether applicable criteria can be considered verified for 
specific months as described.
    Second, at Sec.  155.315(f)(4)(iv)(A)(2), we propose that the 
retroactive period for which an Exchange may provide APTC and CSRs 
would not extend beyond the first day of the first month in which the 
enrollee is enrolled in a QHP. This is consistent with Section 
36B(c)(2)(A)(i) of the Code, which requires an individual to be 
enrolled in a QHP as of the first of a month before the month can be a 
coverage month. Rules regarding Exchange enrollment periods and their 
effective dates are addressed at Sec. Sec.  155.410 and 155.420, with 
some modifications proposed in sections III.A.9. and III.A.10. of this 
proposed rule.
    Third, we propose at Sec.  155.315(f)(4)(iv)(A)(3) that the 
Exchange's determination of an individual's APTC and CSR eligibility 
following the resolution of their DMIs related to applicable enrollment 
information may not be effective earlier than when the individual's 
DMIs were generated. We are proposing this rule to align with 
Exchanges' existing effective date framework, described at Sec.  
155.330(f), under which changes to eligibility are generally \16\ 
implemented prospectively, in relation to when the consumer provides 
the attestations that produce such changes in eligibility. This 
proposal that an Exchange's determination of an individual's APTC and 
CSR eligibility following the resolution of their DMIs may not be 
effective earlier than when the individual's DMIs were generated 
ensures consistent effective dates for consumers who verify the 
applicable enrollment information electronically as compared to those 
who verify the applicable enrollment information via document 
submission during their inconsistency period. To illustrate, consider a 
consumer who does not provide or confirm their eligibility information 
for the upcoming coverage year, and is re-enrolled in a QHP without 
APTC or CSRs effective January 1.\17\ If that consumer subsequently 
updates their application on January 10 and their applicable enrollment 
information are verified in real-time through trusted data sources on 
that same date, then, under the proposed effective date rules at Sec.  
155.330(f)(1), their redetermination of eligibility for APTC and CSRs 
would take effect prospectively, on February 1. If, instead, the same 
consumer updates their application on January 5, the Exchange opens a 
DMI related to the applicable enrollment information on the same date, 
and the DMI is resolved through document submission on January 10,

[[Page 67670]]

then the effective date rules proposed in this section apply. Without 
the proposed policy at Sec.  155.315(f)(4)(iv)(A)(3)--which would 
require that APTC and CSR eligibility determinations not take effect 
before the date the DMI was generated--the consumer could qualify for a 
January 1 effective date for their APTC and CSRs. Specifically, under 
the rules proposed at Sec.  155.315(f)(4)(iv)(A)(1) and Sec.  
155.315(f)(4)(iv)(A)(2), if the information related to the applicant's 
DMIs was verified for January, the consumer's effective date for their 
APTC and CSRs would be January 1 because they were enrolled in a QHP as 
of January 1. This would produce different effective dates for APTC and 
CSRs for consumers who verify electronically versus through 
documentation on the same date. Proposed Sec.  155.315(f)(4)(iv)(A)(3) 
would prevent this illogical outcome. Under this proposal, the 
effective date for the consumer's APTC and CSR eligibility would be 
February 1--consistent with the effective date for the consumer whose 
eligibility was verified electronically.
---------------------------------------------------------------------------

    \16\ Changes to eligibility may be implemented retroactively, in 
relation to when the consumer provides the attestations that produce 
such changes in eligibility, in the case that a consumer qualifies 
for an SEP due to gaining a dependent, described at Sec.  
155.420(b)(2)(i). However, because consumers who qualify for an SEP 
due to gaining a dependent would qualify for the waiver described at 
proposed Sec.  155.315(f)(4)(ii), the effective dates described in 
this section would not be applicable to them, since the resolution 
of their DMIs would not produce a change in their APTC or CSR 
eligibility. These proposed effective date rules therefore would not 
permit changes in eligibility to take effect prior to when the 
consumer provided their attestation of a change in circumstance.
    \17\ See section III.A.7 of this proposed rule for further 
discussion of annual eligibility redeterminations.
---------------------------------------------------------------------------

    Finally, at Sec.  155.315(f)(4)(iv)(A)(4), we propose an exception 
to the effective date rules proposed at Sec.  155.315(f)(4)(iv)(A)(1) 
through (3). Specifically, if these rules would result in an APTC and 
CSR effective date in the prior coverage year, we propose that the 
Exchange would not be permitted to provide or increase APTC for those 
months in the prior year. This exception is intended to mitigate tax 
administration issues and consumer burden that would result if 
Exchanges provided APTC for a month after the Exchange had already 
generated a consumer's Form 1095-A for the coverage year.
    Consider the following example. A consumer submits an application 
to the Exchange on November 15, 2028, and qualifies for an SEP due to a 
November 30, 2028, loss of MEC. The consumer selects a plan on November 
15, 2028, and in accordance with Sec.  155.420(b)(2)(iv), qualifies for 
a coverage effective date of December 1, 2028. The consumer has a DMI 
related to their annual household income for 2028. The consumer chooses 
to enroll in a QHP effective December 1, 2028, without APTC or CSRs. 
Subsequently, the consumer submits documents to the Exchange, and the 
Exchange verifies the consumer's annual household income for 2028 and 
resolves their DMI on February 1, 2029. Were an exception not applied, 
under the rules proposed at Sec.  155.315(f)(4)(iv)(A)(1)-(3), the 
Exchange would be required to provide retroactive APTC, effective 
December 1, 2028.
    This proposed exception is necessary to avoid significant tax 
administration issues. Exchanges generate Form 1095-A for enrollees in 
January following the applicable coverage year, which includes 
information about any APTC paid for each month in the coverage year. 
If, in the scenario described above, the consumer's Form 1095-A is 
generated prior to the Exchange's determination on February 1 that the 
consumer qualifies for APTC for December, the consumer's Form 1095-A 
would reflect that they were enrolled in a QHP but no APTC was paid for 
the month of December. Assume the consumer used this Form 1095-A to 
file their Federal income tax return and claim PTC for the month of 
December. If, in February, the Exchange then provided APTC for the 
month of December, the Exchange would need to issue a corrected Form 
1095-A, a process that generally takes multiple months. Then, upon 
receipt of the corrected Form 1095-A, the consumer would have to file 
an amended 2028 tax return, reduce the December PTC the consumer 
claimed by the amount of APTC paid for the consumer's December 
coverage, and include a tax payment equal to the December APTC, plus 
interest and perhaps penalties, with the 2028 amended return. Instead, 
if there is no retroactive payment of APTC for December, the consumer 
would, on the consumer's 2028 tax return, lower his or her tax 
liability or receive a tax refund for the amount of the December PTC 
for which the consumer is eligible.
    Thus, to alleviate these burdens on Exchanges, consumers, and the 
IRS, we propose that Exchanges would not provide or increase APTC for 
months in prior coverage years. We clarify that this exception applies 
only to APTC; Exchanges would still be required to increase CSRs for 
months in prior coverage years if the enrollee is eligible under the 
rules proposed at Sec.  155.315(f)(4)(iv)(A)(1) through (3). We further 
clarify that, as proposed, this exception would only prevent Exchanges 
from providing APTC for months in a prior coverage year in the specific 
situation where a consumer is enrolled in a QHP and subsequently their 
DMI described at Sec.  155.315(f)(4)(ii) or (iii)(A) is resolved.
    We acknowledge that there are limited additional situations in 
which Exchanges may already be providing or increasing APTC for months 
in a prior coverage year, including if a consumer qualifies for an SEP 
with a retroactive effective date, or in the case of certain appeals. 
At the FFE, consumers are only able to receive prior year APTC through 
manual processes, by calling the Marketplace Call Center and having 
their case reviewed on an individual basis. As a result, we have 
determined that the current volume of cases where prior-year APTC is 
permitted is quite low. In contrast, the consumers to whom the 
effective date rules proposed in this section would apply would be able 
to use an online, automated process to enroll and to resolve their 
DMIs, and we therefore expect that the volume of consumers who may 
qualify for prior year APTC as a result could be quite significant by 
comparison. Therefore, we are only proposing to prevent Exchanges from 
providing prior-year APTC in this specific situation, but we seek 
comment regarding whether this principle should apply in other cases as 
well.
    Regarding the rules proposed at Sec.  155.315(f)(4)(iv)(A), we seek 
comment from issuers and other interested parties on operational 
considerations regarding retroactive provision of APTC and CSRs for 
eligible consumers. Specifically, we understand that providing CSRs for 
weeks or months prior to DMI resolution may be operationally 
challenging for issuers and consumers. We understand that, today, 
correctly re-processing claims that a consumer incurred during a period 
prior to an Exchange's determination of CSR eligibility often requires 
a consumer to manually submit, and an issuer to manually process and 
reimburse, costs incurred by consumers in the past. We seek comment on 
these and any other operational considerations.
    Finally, at Sec.  155.315(f)(4)(iv)(B), we propose that for 
consumers who select a plan and elect that it would only become 
effective once verification requirements are met, as described in 
section III.A.8.b. of this proposed rule, an Exchange's APTC 
eligibility determination would be required to be implemented on the 
same date that the consumer's plan becomes effective. Proposed 
effective date rules for such plan selections are described in section 
III.A.9. of this proposed rule for individuals who make a plan 
selection during the annual OEP, and in section III.A.10. of this 
proposed rule for individuals who select a plan during an SEP. This 
proposal would ensure that, for consumers who elect that their plan 
only become effective once verification requirements are met, 
enrollment and APTC would start on the same date, resulting in a clear 
process for consumers and streamlined communications for Exchanges, as 
well as ensuring that the consumer does not have a period of 
unsubsidized coverage.

[[Page 67671]]

    We seek comment on this proposal. We understand State Exchanges may 
find it challenging to implement these requirements for PY 2028. 
Therefore, we specifically seek comment from State Exchanges regarding 
any risks that State Exchanges would not be able to implement these 
proposed effective date rules by PY 2028, and whether there are 
alternative proposals that could achieve similar outcomes while 
alleviating operational burden.
(v) APTC and CSRs during Other Inconsistency Periods (Sec.  
155.315(f)(4)(v))
    We also propose new Sec.  155.315(f)(4)(v) to specify that 
applicants with DMIs not related to applicable enrollment information 
would be provided APTC and CSRs based on attested application 
information, if otherwise eligible, during an inconsistency period. 
Section 71303(a) of the WFTC legislation provides that no month shall 
be considered a coverage month until an Exchange verifies, using 
applicable enrollment information, an individual's eligibility to 
enroll in a QHP and for APTC. We read this to mean that if an Exchange 
has failed to verify information that is not applicable enrollment 
information, then section 71303(a) of the WFTC legislation does not 
apply. Therefore, we propose that if an individual has a DMI not 
related to the applicable enrollment information, an Exchange would be 
required to follow the existing process established in section 1411 of 
the Affordable Care Act and implementing regulations and provide APTC 
and CSRs, as applicable, during the inconsistency period. An example of 
a DMI not related to the applicable enrollment information is 
verification of AI/AN status, as discussed in Sec.  155.350(c).
(vi) Conclusion
    Overall, subject to certain exceptions described in sections 
III.A.4.c. and III.A.4.d. of this proposed rule, these proposed changes 
would prevent applicants from receiving APTC and CSRs during 
inconsistency periods when an applicant has a DMI related to the 
applicable enrollment information.
    We seek comment on these proposals.
c. Family Size Special Enrollment Period Waiver (Sec.  
155.315(f)(4)(ii))
    In accordance with section 1.36B-3(c)(6)(ii) of the PTC proposed 
rule (91 FR 65499), we propose to amend Sec.  155.315(f)(4)(ii) to 
require Exchanges to ensure that APTC and CSRs, as applicable, are 
provided on behalf of an applicant based on the information attested on 
the application for coverage during an inconsistency period described 
in Sec.  155.315(f)(4)(ii), when the applicant, or a member of the 
applicant's tax household, is eligible to enroll during an SEP in 
accordance with Sec.  155.420(d)(2)(i), also known as the birth, 
adoption, and marriage SEP, or Sec.  155.420(d)(2)(ii), also known as 
the loss of a dependent (or consideration as a dependent) through 
divorce, legal separation or death SEP. We refer to these SEPs 
collectively as the ``change in family size SEPs'' throughout this 
section. These SEPs would be subject to the requirement to verify 75 
percent of enrollments via SEPs that were finalized in the HHS Notice 
of Benefit and Payment Parameters for 2027 (2027 Payment Notice) (97 FR 
29526).\18\ In addition, we propose adding Sec.  155.315(f)(4)(iii)(A) 
that also explains that current enrollees who are eligible to re-enroll 
during an SEP in accordance with Sec.  155.420(d)(2)(i) or (ii) are 
also eligible for this exception to ensure that APTC and CSRs are 
provided based on the information attested to on their updated 
application.
---------------------------------------------------------------------------

    \18\ As of the date of this publication, this policy has been 
stayed by an order issued on July 16, 2026, in the City of Columbus 
et al. v. Kennedy et al. (1:26-cv-02215).
---------------------------------------------------------------------------

    Section 71303(a) of the WFTC legislation adds section 36B(c)(5)(E) 
of the Code, which explicitly allows for a waiver of the verification 
requirement in section 36B(c)(5)(A) of the Code, at the option of the 
Secretary of the Treasury, in the case of an individual who enrolls in 
a QHP during an SEP due to a change in family size. We propose to 
require Exchanges to adopt this exception set forth in proposed 
Treasury Reg. Sec.  1.36B-3(c)(6)(ii) (91 FR 65499). Adopting this 
exception would allow Exchanges to consider a month to be a coverage 
month prior to verification of the requirements set forth in the 
proposed Sec.  1.36B-3(c)(6) (91 FR 65494). Under Sec.  1.36B-3(a) (91 
FR 65494), for a consumer to be eligible for PTC for that month, a 
month is required to be a coverage month. Furthermore, as mentioned 
earlier, we interpret section 1411(a)(2) of the Affordable Care Act as 
requiring Exchanges to make APTC and CSR eligibility determinations 
consistent with the PTC eligibility requirements of section 36B of the 
Code. Taking those two requirements together, we propose to require 
Exchanges to adopt this exception such that a month may be a coverage 
month, and APTC and CSRs may be paid, prior to verifying the 
information in proposed Treasury Reg. Sec.  1.36B-3(c)(6)(i) (91 FR 
65494), which is the same as the information proposed in Sec.  
155.315(f)(4)(ii) of this proposed rule, if an individual, either is 
eligible to newly enroll or re-enroll in a QHP during an SEP that is 
triggered by a change in family size as allowed at Sec.  
155.420(d)(2)(i) or (ii). If finalized, this exception would allow a 
consumer who qualifies for a change in family size SEP to be determined 
eligible for APTC and CSRs (if otherwise eligible) based on attested 
application information during an inconsistency period, as they are 
under current rules. We note that if this exception is finalized as 
proposed, consumers would still be subject to existing Exchange 
processes to verify eligibility to enroll in a QHP and eligibility for 
APTC and CSRs, as applicable, consistent with section 1411(c) and (d) 
of the Affordable Care Act and implementing regulations.
    As explained previously, we interpret section 1411(a)(2)(A) of the 
Affordable Care Act as requiring Exchanges to make APTC and CSR 
eligibility determinations consistent with the PTC eligibility 
requirements of section 36B of the Code. Therefore, it is necessary for 
HHS to also adopt the Secretary of Treasury's waiver of the 
verification requirements of section 36B(c)(5)(A) of the Code to ensure 
that Exchanges make APTC and CSR eligibility determinations consistent 
with PTC eligibility determinations. Additionally, by aligning our 
requirements with those proposed by the Secretary of Treasury in the 
rule described above, HHS can ensure timely and continuous coverage for 
enrollees who qualify for SEPs due to a change in family size, 
particularly consumers who are adding newborns or dependents to their 
families. There are several situations where, without this exception, 
consumers could potentially lose APTC and CSRs at critical junctures of 
needing medical care, including the newborn and postpartum periods.
    The requirements specified in section 1411(c) and (d) of the 
Affordable Care Act and the implementing regulations at Sec. Sec.  
155.315 and 155.320, which are the basis for Exchange verification 
processes, require verification of information provided by applicants, 
including citizenship or immigration status, household income and 
family size, and eligibility for or enrollment in employer-sponsored 
coverage. If a consumer, either new or current, is eligible to enroll 
or re-enroll during a family size SEP, generates DMIs related to the 
applicable enrollment information, and then is unsuccessful at 
resolving those DMIs and loses their APTC, the consumer may still be 
allowed PTC for the months during the inconsistency period when filing 
their

[[Page 67672]]

tax return and reconciling their APTC with their actual allowed PTC.
    Section 71303(a) of the WFTC legislation allows a waiver of the 
verification requirement in section 36B(c)(5)(A) of the Code for an 
individual who enrolls in a QHP during a SEP based on ``a change in the 
family size of the individual.'' We read this as referring to the 
following current SEPs: gaining a dependent through marriage, birth, 
adoption, placement for adoption, placement in foster care, or through 
child support or another court order in Sec.  155.420(d)(2)(i); and 
loss of a dependent or consideration as a dependent through divorce, 
legal separation, or death in Sec.  155.420(d)(2)(ii) (if offered by an 
Exchange). To qualify for the SEP at Sec.  155.420(d)(2)(i) through 
marriage, one or both spouses need to demonstrate having one or more 
days of MEC in the prior 60 days preceding the date of marriage under 
Sec.  155.420(d)(2)(i)(A). Exchanges on the Federal platform do not 
currently offer the SEP at Sec.  155.420(d)(2)(ii), as generally the 
consumer who is losing or is no longer considered a dependent qualifies 
for a loss of MEC SEP, thereby preventing a loss of coverage.
    We are requesting comment specifically on whether Exchanges should 
be required to offer the loss of dependent or consideration as a 
dependent SEP offered at Sec.  155.420(d)(2)(ii) so that consumers who 
are eligible to enroll during this SEP may continue to qualify for APTC 
and CSRs based on their attestation during an inconsistency period that 
occurs due to updating their eligibility information to the Exchange. 
While consumers are already required to promptly report any changes 
that may affect their APTC or CSR eligibility, we are of the view that 
doing so is more important than it has been previously, in light of the 
change that removes APTC repayment caps in section 71305 of the WFTC 
legislation. For consumers that have been determined eligible to enroll 
during a family size SEP as described at Sec.  155.420(d)(2) and 
otherwise have a DMI due to the new information on their application, 
this statutorily allowed exception ensures that consumers receive the 
APTC and CSRs that most closely reflect their attested-to situation, 
thereby minimizing the potential for larger tax liabilities. Requiring 
Exchanges to offer the loss of dependent or dependent status SEP would 
also prevent individuals who lose dependent status--for example, due to 
divorce or death of the primary policyholder--from losing potential 
APTC and CSRs until they newly meet pre-verification requirements.
    For these reasons, we are proposing to amend Sec.  
155.315(f)(4)(ii) and add new Sec.  155.315(f)(4)(iii)(C) to require 
all Exchanges to determine eligibility for APTC and CSRs based on the 
attested application information during an applicant's inconsistency 
period for DMIs related to the applicable enrollment information if the 
applicant's household is eligible to enroll during a family size SEP in 
accordance with Sec.  155.420(d)(2)(i) and (ii). The proposed change 
would ensure that both new applicants and enrollees who have previously 
verified their information under Sec.  155.315(f)(4)(ii) and (iii) are 
eligible for APTC and CSRs based on the attested application 
information if they are eligible to enroll during a change in family 
size SEP.
    We seek comment on this proposal. We understand State Exchanges may 
find it challenging to implement these requirements for PY 2028. 
Therefore, we are considering providing flexibility for State Exchanges 
to delay implementation of the change in family size SEP exception 
until PY 2029. We seek comment, in particular from State Exchanges, 
about whether the availability of this flexibility would be useful to 
ease the burden of implementing the requirements in this proposed rule.
d. Eligibility Redeterminations During the Plan Year
    Consistent with the PTC proposed rule (91 FR 65499), we propose the 
addition of new Sec.  155.315(f)(4)(iii) to describe the requirements 
for providing APTC and CSRs for enrollees who have reported a change to 
eligibility criteria during the plan year after an Exchange has 
completed verification of those same criteria using the enrollee's 
information from their immediately preceding eligibility determination. 
As outlined in section II.A. of this proposed rule, section 71303(a) of 
the WFTC legislation provides additional criteria for a month to be 
considered a coverage month. Specifically, a month generally may not be 
a coverage month for an enrollee in a QHP for any month that an 
Exchange fails to verify specific criteria related to the enrollee's 
eligibility to enroll in a QHP through an Exchange and, to the extent 
relevant, for APTC for the coverage for that month using certain 
criteria. More specifically, beginning with PY 2028, an Exchange must 
verify eligibility for enrollment in a QHP and APTC using the following 
information before a month is considered a coverage month and PTC may 
be paid: (1) household income and family size; (2) eligible noncitizen 
status; (3) any health coverage status or eligibility for coverage; (4) 
residency; and (5) other information as determined by the Secretary of 
the Treasury, in consultation with the Secretary of HHS.
    In proposed Sec.  155.315(f)(4)(iii)(A) and (B), we propose 
Exchange procedures regarding the provision of APTC and CSRs when an 
enrollee reports a change that generates one or more DMIs related to 
the applicable enrollment information. If the reported change results 
in an amount of APTC or CSRs that is in excess of or equal to the 
amount of APTC or CSRs previously determined for the individual, we 
propose that Exchanges would be required to continue providing APTC and 
CSRs (as applicable) during inconsistency periods at the same amount as 
previously determined. If the reported change results in an amount of 
APTC or CSRs that is lower than the amount previously determined for 
the individual, then we propose that Exchanges would lower APTC and 
CSRs based on the information provided by the applicant during an 
inconsistency period.
    Section 71303(a) of the WFTC legislation amends the definition of 
``coverage month'' and conditions PTC eligibility on successful 
verification of applicable enrollment information (that is, the 
criteria described in proposed Sec.  155.315(f)(4)(ii)) listed above. 
We construe this change as a requirement that Exchanges must comply 
with in addition to (not in place of) existing verification 
requirements prescribed by sections 1411 and 1412 of the Affordable 
Care Act. Importantly, while section 71303(a) of the WFTC legislation 
requires that information be verified prior to treating a month as a 
coverage month (that is, before PTC can be allowed for an applicant's 
coverage), we propose this process would not immediately supersede all 
prior verifications or require automatic termination of APTC and CSRs 
at the point that an enrollee reports a change within the plan year. 
Instead, we read section 71303(a) of the WFTC legislation to mean that 
any verification of applicable enrollment information must remain 
effective for the duration of the plan year, but, if an enrollee 
reports a change resulting in a DMI related to the applicable 
enrollment information, additional verification is required only before 
any additional APTC may be paid. For example, consider an enrollee 
receiving $250 per month in APTC. The enrollee reports a decrease in 
projected annual household income during the plan year that would make 
the enrollee eligible for $300 per month in APTC.

[[Page 67673]]

The enrollee's income cannot be verified with IRS, resulting in a DMI. 
Section 71303(a) of the WFTC would prohibit an Exchange from providing 
the enrollee with the additional $50 per month in APTC until the 
enrollee's income was verified, but it would not permit the Exchange to 
end APTC during the DMI period entirely (unless otherwise permitted).
    Additionally, even if 71303(a) of the WFTC legislation did not 
compel this outcome, the Exchange may continue to draw authority from 
section 1412(b) of the Affordable Care Act for changes reported during 
the benefit year. Specifically, section 1412(b)(2) of the Affordable 
Care Act allows the Secretary of HHS to establish procedures to 
determine APTC on the basis of information other than an enrollee's 
prior tax return data when an enrollee's application form demonstrates 
substantial changes in circumstances, such as changes in income, family 
size, or other significant changes affecting eligibility.\19\
---------------------------------------------------------------------------

    \19\ As outlined in Sec.  155.330(b), current enrollees who 
previously sought and received an eligibility determination from the 
Exchange are required to report changes that impact their 
eligibility within 30 days of such change. If an Exchange receives 
updated information, the enrollee's eligibility is redetermined in 
accordance with Sec.  155.305 and the enrollee is notified about the 
determination. If an Exchange is unable to verify the updated 
information, the enrollee receives a DMI and is provided with a 90/
95-day inconsistency period to submit documentation that verifies 
the attested application in accordance with Sec. Sec.  155.315 and 
155.320.
---------------------------------------------------------------------------

    Accordingly, we propose a framework that would require an Exchange 
to maintain or decrease an enrollee's previously determined APTC or CSR 
amount (where applicable) if a reported change generates a DMI related 
to the applicable enrollment information after the enrollee was 
determined eligible for APTC or CSR for a given plan year. The 
maintained or decreased APTC amount would be applicable until an 
Exchange either resolves the DMI, the consumer reports another change 
in circumstance, or until the end of the inconsistency period during 
which the updated information remains unverified.
    Throughout this paragraph, we use ``previously verified'' or 
``previously determined'' to reference the enrollee's most recent 
verification or determination conducted by the Exchange. We propose in 
Sec.  155.315(f)(4)(iii)(A) that when an individual reports a change 
that results in an amount of APTC or CSRs greater than or equal to the 
amount of APTC or CSRs previously determined for the individual, an 
Exchange would be required to maintain APTC or CSRs at the previously 
verified amount during an inconsistency period. If the DMI is not 
resolved, under section 1411(e)(4)(B)(ii) of the Affordable Care Act 
and regulations at Sec. Sec.  155.315(f)(5) and 155.320(c)(3)(vi)(F) 
through (G), an Exchange would be required to redetermine eligibility 
for enrollment in a QHP and for APTC and CSRs, as applicable, on the 
basis of records maintained by specific Federal officials as outlined 
in section 1411(c) of the Affordable Care Act, which may include 
termination of enrollment in a QHP and/or of APTC and CSRs. We propose 
the approach in Sec.  155.315(f)(4)(iii)(A) because until new 
information is verified, maintaining an enrollee's prior verified 
eligibility preserves program integrity and eases burden on enrollees 
related to reporting changes to the Exchanges, as stated later in this 
section. This is particularly relevant as it is reasonable for an 
individual to experience changes that significantly impact their 
eligibility, resulting in DMIs.
    For example, consider a scenario where an enrollee reports a 
decrease in income from 350 percent of the FPL to 150 percent of the 
FPL, corresponding with an increase in APTC and new eligibility for 
CSRs, and resulting in a household income DMI. Under proposed Sec.  
155.315(f)(4)(iii)(A), Exchanges would be required to maintain the 
previously determined lower amount of APTC and CSRs based on previously 
verified information during the inconsistency period. Once the 
household income DMI is successfully resolved, an Exchange would be 
required to redetermine eligibility and adjust the amount of APTC or 
CSRs upwards based on the consumer's verified income attestation, with 
an effective date consistent with proposed Sec.  155.315(f)(4)(iv) and 
other proposed changes regarding effective dates following resolution 
of DMIs outlined in section III.A.6.b. of this proposed rule. As noted 
previously, if the DMI is not resolved, the Exchange would be required 
to redetermine QHP and APTC and CSR eligibility, as applicable, on the 
basis of records maintained by a trusted data source, which may include 
removal of QHP and/or APTC and CSR eligibility.
    By maintaining the lower amount of APTC and CSRs based on the 
previously verified information during the inconsistency period, 
Exchanges would ensure that APTC and CSRs are only ever provided to 
enrollees during an inconsistency period at a level that does not 
exceed the amount provided based on previously verified information. 
Additionally, this proposed policy supports program integrity by 
ensuring that accurate amounts of APTC and CSRs are being provided on 
behalf of enrollees.
    We acknowledge that this proposal would result in many consumers 
receiving less APTC and CSRs during an inconsistency period than they 
are ultimately determined eligible for when their DMIs are resolved. 
For APTC, consumers could be made whole during the tax filing and 
reconciliation process. We acknowledge that this may present a gap for 
some enrollees regarding CSRs when compared to APTC, because enrollees 
with APTC less than their PTC may claim the difference as a tax credit 
on their tax return for the year of coverage whereas there is no 
similar process for CSRs. However, we are of the view that this 
proposed policy strikes a balance between ensuring responsible Exchange 
operations regarding the provision of APTC and CSRs and encouraging 
enrollees to report changes.
    In contrast, consider the opposite scenario, where an enrollee 
reports an increase in income from 150 percent of the FPL to 350 
percent of the FPL, corresponding with a decrease in APTC and 
ineligibility for CSRs, and resulting in a household income DMI. We 
propose in Sec.  155.315(f)(4)(iii)(B) that Exchanges would be required 
to adjust APTC or CSRs downward immediately after application 
submission based on the information provided by the enrollee on the 
application. Under this proposal, since the enrollee was previously 
verified for a higher amount of APTC or CSRs, the enrollee would be 
determined eligible for a lower amount of APTC or CSRs during the 
inconsistency period based on their newly attested applicable 
enrollment information. By requiring the Exchange to decrease APTC or 
CSRs in this manner, this proposal would help ensure that the Exchange 
does not pay out more APTC than that for which the consumer may be 
eligible based on the consumer's reported increase in income.
    We are of the view that the policies described in proposed Sec.  
155.315(f)(4)(iii)(A) and (B) are permitted under section 1412(b)(2) of 
the Affordable Care Act, which affords discretion to the Secretary to 
modify procedures for making advanced determinations as circumstances 
warrant. In other words, this broad authority allows the Secretary to 
structure Exchange rules for determining an enrollee's APTC or CSRs 
when the enrollee reports a change during the benefit year. We are of 
the view that this interpretation allows an Exchange to maintain or 
adjust APTC or

[[Page 67674]]

CSRs downwards for instances described in proposed Sec.  
155.315(f)(4)(iii)(A) and (B). We are of the view that this proposed 
framework--maintaining or reducing APTC or CSRs during the 
inconsistency period for an enrollee following a mid-year change that 
results in a change to the amount of, or eligibility for, APTC or 
CSRs--best achieves Congressional intent of section 71303 of the WFTC 
legislation. Under both proposed Sec.  155.315(f)(4)(iii)(A) and (B), 
enrollees would continue to receive APTC and CSRs during the 90/95-day 
DMI period as long as they are otherwise eligible for APTC.
    Under this proposed framework, Exchange determinations would always 
utilize verified information. In the first instance where an enrollee's 
reported change would result in an increase of APTC and CSRs, the 
Exchange would maintain APTC and CSRs at the previously verified level 
during the inconsistency period while verification of reported changes 
is pending at the Exchange. In the second instance, when the enrollee's 
reported change would result in a decrease in APTC and CSRs, the 
Exchange would base their determination on the enrollee's newly 
reported information. This determination would not occur in the absence 
of verified information. Rather, this determination (and the resulting 
provision of APTC and CSRs during the inconsistency period) would 
reflect both the enrollee's newly reported information and the fact 
that the Exchange previously verified the enrollee eligible for a 
higher amount of APTC and CSRs. We are of the view that this approach 
is critical, as the only alternative would be to disregard an 
enrollee's attestation that supports eligibility for less APTC and CSRs 
than previously verified. Importantly, the downward adjustment of APTC 
and CSRs based on the enrollee's attestation simply adjusts the 
verified baseline amount of APTC and CSRs downward to limit the 
enrollee's exposure to tax liability. We considered that an enrollee 
would have less incentive to report a change that results in a decrease 
in APTC or CSRs if they were not aware of the tax implications and did 
not wish to limit their tax liability.
    In contrast, some enrollees may be inclined to report a change that 
results in an increase of APTC and CSRs because they are unaware of the 
tax implications or are focused on the short-term benefit of doing so 
(that is, lower monthly premiums). For these reasons, we believe the 
proposed approach best balances the interests of protecting consumers 
from increased tax liability and program integrity. Ultimately, the 
provision of APTC and CSRs during the inconsistency period while 
verification of reported changes is pending at the Exchange would use 
previously verified information as a foundational element for 
determinations. This two-pronged approach would ensure that enrollees 
and households do not receive more APTC and CSRs than they are verified 
for.
    We considered alternatives to this proposal. We considered an 
approach in which Exchanges would be required to maintain an enrollee's 
current APTC or CSRs (that is, maintain a higher amount of APTC despite 
the enrollee's attested increased income) during an inconsistency 
period described in Sec.  155.315(f)(4)(ii) when the enrollee reports a 
change that would result in a decrease in APTC or CSRs. However, since 
section 71305 of the WFTC legislation eliminates the limitation on 
repayment of excess APTC for tax years after December 31, 2025 (as set 
forth in section 36B(f)(2) of the Code), this approach could result in 
a consumer incurring a large tax liability despite correctly reporting 
a change. Therefore, our proposed policy serves as a key consumer 
protective measure by helping to safeguard consumers from large APTC 
repayments. We also considered requiring Exchanges to provide the 
higher amount of APTC or CSRs when an enrollee reports a change that 
results in an increase of APTC or CSRs, but encouraging consumers to 
take less APTC--specifically the amount they were receiving prior to 
reporting a change in circumstances--to avoid the risk of incurring a 
significant tax liability if their attestation was not verified. 
However, we determined that this would create consumer confusion and 
may not be effective as consumers would need to take additional actions 
to manually adjust the amount of APTC applied to their monthly premium 
if desired.
    This alternative operational approach could result in consumer 
confusion and friction, which may inadvertently disincentivize 
consumers from reporting changes. Importantly, we are of the view that 
structuring Exchange operations in the manner proposed would ensure 
accurate APTC determinations to the extent possible. Such a posture 
would enhance program integrity by ensuring that enrollees receive no 
more APTC than they have been determined eligible for after 
verification of their applicable enrollment information. Ultimately, 
such an approach reduces unnecessary Federal APTC outlays in the event 
attestations are inaccurate while safeguarding consumers from large tax 
liabilities, preventing an unnecessary cycle of APTC payment and 
repayment.
    We considered another alternative approach, which would require 
Exchanges to remove APTC or CSRs during inconsistency periods. This 
approach would require individuals to pay the full premium to maintain 
coverage, which could be unaffordable for many individuals and result 
in them terminating coverage. That outcome could have a destabilizing 
impact on risk pools due to increases in adverse selection, as 
individuals with greater health needs would be more likely to maintain 
coverage (whether by quickly resolving DMIs or paying the full cost of 
premiums) than healthy individuals. Furthermore, we are of the view 
that it is important to structure the Exchange rules such that 
enrollees are motivated to report changes as required. Requiring 
Exchanges to terminate APTC or CSRs for consumers who report a change 
that results in a DMI related to the applicable enrollment information 
would likely discourage consumers from reporting changes.
    We acknowledge that this proposal may require Exchanges to modify 
application and enrollment processes to accommodate scenarios where 
APTC and CSRs are maintained and those where APTC and CSRs are 
decreased. We especially acknowledge the burden that this change may 
impose on State Exchanges and the operational costs that may be 
incurred to implement these changes. However, given the high likelihood 
that individuals may experience significant changes during the benefit 
year after their applicable enrollment information has been verified, 
it is critical that Exchanges implement these new requirements to 
motivate individuals to report changes that accurately represent their 
circumstances. Exchanges may leverage existing infrastructure to 
implement these changes, such as current functionality that enables 
Exchanges to maintain APTC and CSRs during an inconsistency period, or 
functionality that adjusts or removes APTC as required by section 
1411(e)(4)(B)(ii) of the Affordable Care Act as described above.
    We also acknowledge that this proposal would require changes to 
existing enrollee communication procedures and associated 
infrastructure. In particular, enrollees may find it difficult to 
distinguish between scenarios where their APTC or CSRs would be 
maintained compared to those where APTC or CSRs would be reduced. 
Importantly, while alternative approaches such as removing APTC or CSRs 
altogether or requiring enrollees to

[[Page 67675]]

manually adjust APTC may appear simpler on their face, such approaches 
would simply shift complexity on to the enrollee at a later moment in 
the enrollment process, such as at the point of plan selection or 
enrollment where an enrollee (or an agent or broker applying on their 
behalf) must manually adjust their APTC or at tax reconciliation, where 
the enrollee may incur tax liabilities. Such approaches would likely 
deter enrollees from reporting changes during the benefit year.
    We expect Exchanges to identify communication strategies that are 
tailored to their enrollee populations, such as updated eligibility 
determination notices that describe APTC or CSR changes following a 
mid-benefit year change, text message alerts to enrollees when APTC or 
CSRs are reduced, dynamic messaging for consumers after application 
submission and so on. We note that State Exchanges have successfully 
absorbed comparable operational changes, such as changes resulting from 
Medicaid unwinding from 2023-2024, suggesting that system changes such 
as these are likely within existing institutional capacity and would 
not impose a burden once integrated into normal operations. We 
anticipate that enrollee familiarity (as well as that of assisters, 
agents, and brokers that assist enrollees) will increase across 
enrollment cycles as their application better reflects the enrollee's 
most recent applicable enrollment information.
    To summarize, we propose the addition of Sec.  
155.315(f)(4)(iii)(A) and (B) to describe the requirements for 
providing APTC and CSRs for enrollees who have reported a change during 
the plan year that results in a DMI related to applicable enrollment 
information (such as household income), after an Exchange has completed 
verification of those same criteria for the same plan year using the 
enrollee's information from their immediately preceding eligibility 
determination. We propose that Exchanges would be required to maintain 
the amount of APTC or CSRs if a reported change results in an amount of 
APTC or CSRs that is in excess of or equal to the amount of APTC or 
CSRs previously determined for the individual. We propose that 
Exchanges would be required to reduce APTC or CSRs based on the 
individual's attested income if a reported change results in an amount 
of APTC or CSRs that is lower than the amount previously determined for 
the individual.
    We seek comment on this proposal. We understand State Exchanges may 
find it challenging to implement these requirements for PY 2028. 
Therefore, we are considering providing flexibility for State Exchanges 
to delay implementation of this proposal for enrollees who have 
reported a change during the plan year until PY 2029. We seek comment, 
in particular from State Exchanges, about whether the availability of 
this flexibility would be useful to ease the burden of implementing the 
requirements in this proposed rule.
5. Verification Process Related to Eligibility for Insurance 
Affordability Programs (Sec.  155.320(c))
    We do not propose any changes to the existing regulatory 
requirements at Sec.  155.320(c) related to verification of family size 
as described further in this section. However, we seek comment on how 
we might strengthen requirements for Exchanges to verify family size in 
the future. We also seek comment on how Exchanges could verify family 
size using data sources, and which data sources we should consider 
making available for Exchanges, with the ultimate goal of increasing 
program integrity, while minimizing burden for Exchanges and consumers, 
and limiting the cost for Exchanges to procure new data sources.
    As background, to be eligible to receive APTC or CSRs, applicants 
or enrollees must provide certain information regarding the individuals 
that make up their tax household, including their relationship to the 
tax filer (the tax anchor on the application) and tax filing status, 
according to section 1411(b)(3)(A) of the Affordable Care Act. Under 
section 1411(c)(3) of the Affordable Care Act, the Secretary of HHS 
must submit the family size information collected by Exchange 
applications to the Secretary of the Treasury for verification of both 
household income and family size.
    Per current Sec.  155.320(c)(3)(i)(A), an Exchange must require an 
applicant or enrollee applying for coverage with financial assistance, 
such as APTC and CSRs, to attest to information about the individuals 
that comprise the tax filer's family. If an applicant or enrollee 
attests that a change in circumstance has occurred or is likely to 
occur that would result in an inaccurate projection of their family 
size for the year for which they are applying for coverage, and so it 
is not representative of the family size for the plan year, an Exchange 
may accept the applicant or enrollee's attestation without further 
verification, per Sec.  155.320(c)(3)(i)(C), as long as the data 
provided by the applicant is reasonably compatible with other 
information provided about their family. If the data provided by the 
applicant or enrollee is not reasonably compatible with other 
information provided by the application filer for the family, an 
Exchange generally must utilize data obtained through other electronic 
data sources to verify the attestation. If such data sources are 
unavailable or information in such data sources is not reasonably 
compatible with the applicant or enrollee's attestation, an Exchange 
must request additional documentation to support the attestation, 
consistent with current Sec.  155.315(f).
    Currently, the FFE application prompts the applicant or enrollee to 
provide information about their tax filing status and the current 
makeup of their household, including any dependents they plan to claim 
on their Federal income tax return. However, the FFE application does 
not allow the applicant or enrollee to provide a specific number of 
family members in their household. Rather, the FFE's eligibility logic 
works to calculate the applicant's family size based upon the 
information the applicant or enrollee has provided in their application 
regarding tax filing status and any dependents they listed.
    In light of the new requirements in the WFTC legislation, we wish 
to revisit family size verification and solicit comment from interested 
parties on possible alternatives, new data sources, or other 
enhancements that Exchanges could implement to strengthen family size 
verification. We explored additional ways Exchanges could strengthen or 
enhance their verification procedures for family size, but discovered 
some important challenges Exchanges would likely face, which we discuss 
in more detail in the remainder of this section.
    First, we are not aware of any existing external data source 
currently used by any Federal agency to verify an applicant or 
enrollee's current or future family size, other than Federal income tax 
return data that Exchanges access through the IRS Hub service. 
Exchanges could potentially use this data to verify family size by 
calculating the number of dependents an applicant or enrollee claimed 
on their tax return and comparing with the number of dependents 
attested to on the coverage application; however, any such estimate is 
likely to often be incorrect, since IRS displays tax data for the most 
recent tax year for which data is available, which is typically 1 to 3 
years prior to the current coverage year, due to the time delay between 
a tax return being filed and the time period the tax data represents, 
and the consumer's family

[[Page 67676]]

size may have changed during that timeframe. Furthermore, the 
operational process to determine the number of dependents a tax filer 
plans to claim on their tax return is difficult for both an Exchange 
and consumers because changes to family size during the plan year may 
cause inconsistencies when trying to match against IRS data. For 
example, an applicant or enrollee who gains a dependent via a birth in 
October 2026 and applies for coverage during the OEP in November 2026, 
would not be able to electronically verify his or her family size using 
IRS data. This is because that new dependent was not included on the 
applicant's most recent Federal income tax return and, therefore, IRS 
data will not have any record of that new dependent until the applicant 
or enrollee claims them on their 2026 tax return filed in 2027. A 
relative dearth of data available to prove changes in a consumer's tax 
household size is a major challenge with verifying family size through 
IRS tax data.
    A second challenge for Exchanges verifying family size is 
navigating the complicated rules relating to who qualifies as a tax 
filer's dependent on their tax return. In general, a consumer is able 
to claim an individual as a dependent if (1) the individual is a U.S. 
citizen, a U.S. national, U.S. resident, or a resident of Canada or 
Mexico, (2) the individual, if married, does not file a joint return 
with his or her spouse except in limited situations, and (3) the 
individual is a qualifying child or a qualifying relative of the 
consumer. Additional tests must be met for an individual to qualify as 
a qualifying child or qualifying relative of a consumer. In addition, 
it is possible for an individual to be a qualifying child of more than 
one tax filer, and in those situations, there are tiebreaker rules to 
determine which tax filer can claim the individual as a dependent. 
Because of these complex rules, it may be difficult for tax filers to 
provide documentation supporting the attested family size provided on 
their application.
    While considering the current challenges that Exchanges face 
regarding family size verification discussed previously and the new 
requirements in section 71303 of the WFTC legislation, we also 
considered two potential approaches to strengthen or enhance family 
size verification for applicants or enrollees applying for Exchange 
coverage with APTC/CSRs. The first approach involved setting a family 
size DMI for all applicants or enrollees whose reported household size 
did not match their household size in IRS tax data. Based on our 
analysis of FFE data that looked at IRS response codes from consumers 
for PY 2024 and PY 2025, we found that household size data from IRS 
could not be returned for 13,423,627 applications, out of a total of 
30,328,781, which is roughly 44 percent. While many reasons may have 
contributed to a lack of available IRS data for these consumers, this 
approach could result in almost half of all applicants receiving a 
family size DMI, which would require significant technical and 
operational updates for all Exchanges. Additionally, we expect that the 
percentage of applicants or enrollees who successfully resolve their 
family size DMI would be low, given the lack of available documentation 
types for an applicant to prove tax family size. Moreover, there is a 
high likelihood of inaccurate DMI processing, due to the complexities 
in tax rules for claiming dependents. A notable concern with this 
approach is that if an applicant's or enrollee's family size DMI could 
not be resolved, then APTC would be removed for the entire household. 
Finally, this approach may have negative impacts on the risk pool as it 
may lower overall participation in Exchanges due to the increased 
burden to resolve DMIs, thus increasing the risk of adverse selection 
as certain populations, such as younger individuals, would choose to 
forego Exchange coverage.
    A second option we explored was a targeted, risk-based approach to 
modifying the family size verification process. We explored if an 
Exchange could either randomly verify a specific percentage of 
households, verify family size changes greater than two when compared 
to IRS tax data, verify family sizes greater than a certain amount of 
people, or verify non-applicant dependents without an SSN. This option 
would require the same technical and operational updates as the first 
option but would result in fewer DMIs. However, similar to the first 
option, we anticipate the percentage of applicants who would 
successfully resolve their family size DMI would be low due to the lack 
of available documentation options to prove tax family size. This 
option would likely have less of a negative impact on the risk pool as 
compared to the first option as a smaller subset of applicants would 
receive a DMI.
    Given that Exchanges face such extensive challenges and costs 
associated with enhancing family size verification operations, we 
propose to retain the current regulatory requirements regarding 
verification of family size as outlined in Sec.  155.320(c). We are of 
the view that the current regulatory requirements and Exchange 
operations to verify family size are sufficient given the challenges we 
discussed earlier in this section. We note that historically, we have 
seen very limited cases of fraud as it relates to family size, however, 
we are still interested in ways to potentially strengthen or enhance 
family size verification, in a way that is both cost-efficient for 
Exchanges and minimally burdensome on consumers.
    We seek comment on alternatives and invite interested parties to 
share their experiences with family size verification, including 
challenges, risk for family size fraud, feasibility of other 
verification approaches such as risk-based verification, and cost/
budget impacts.
6. Eligibility Redetermination During a Plan Year (Sec.  155.330)
a. Effective Dates for Enrollee-Reported Changes (Sec.  155.330(f)(1))
(i) Summary of Proposed Effective Dates for Enrollee-Reported Changes
    In Sec.  155.330(f)(1), we propose that if an Exchange redetermines 
an enrollee's eligibility to enroll in a QHP, for APTC, or for CSRs 
because the enrollee has provided updated information to the Exchange, 
such redetermination of eligibility would become effective on the first 
of the month following an Exchange's eligibility redetermination. We 
clarify that, throughout this section, when we refer to a 
redetermination of APTC or CSR eligibility, we are referring to both 
redeterminations that result in a consumer becoming eligible for a 
different amount or level of APTC or CSR, as applicable, and 
redeterminations that result in a consumer becoming newly eligible or 
ineligible for APTC or CSRs.
    The proposal in Sec.  155.330(f)(1) would maintain the general rule 
currently in Sec.  155.330(f)(1)(i) that eligibility updates resulting 
from enrollee-reported changes must be effective on the first of the 
month following an Exchange's eligibility redetermination. Currently, 
Sec.  155.330(f)(1)(i) provides that eligibility changes ``resulting 
from a determination under this section'' must be effective on the 
first of the month following the date of the consumer's eligibility 
determination notice, subject to certain exceptions enumerated in Sec.  
155.330(f)(2) through (5). Determinations ``under this section'' 
include both enrollee-reported changes as described in Sec.  
155.330(e)(1), as well as determinations made as part of the periodic 
data matching process described in Sec.  155.330(e)(2). We propose 
effective dates for determinations made as part of the periodic data 
matching process in proposed Sec.  155.330(f)(3),

[[Page 67677]]

discussed in section III.A.6.c. of this proposed rule.
    Proposed Sec.  155.330(f)(1) would apply to eligibility 
redeterminations when an enrollee provides updated information to an 
Exchange and the Exchange determines the enrollee has an inconsistency. 
For example, Sec.  155.330(f)(1) would apply if an Exchange determines 
that an enrollee's APTC or CSRs, as applicable, needs to be reduced 
during their inconsistency period because they have a DMI as described 
in proposed Sec.  155.315(f)(4)(iii)(B). In these cases, the 
redetermination of the enrollee's APTC or CSRs eligibility would be 
effective on the first of the month following the Exchange's 
eligibility redetermination.
    At Sec.  155.330(f)(1)(i), we propose an exception such that, if 
the Exchange redetermines an enrollee's eligibility because the 
enrollee has provided updated information to the Exchange, and the 
Exchange also determines that the enrollee qualifies for certain SEPs 
described in Sec.  155.420(b)(2)(i) or (b)(2)(iii), then the Exchange 
would implement the enrollee's eligibility redetermination on the 
coverage effective dates described in Sec.  155.420(b)(2)(i) or 
(b)(2)(iii), respectively.
    Current Sec.  155.330(f)(1)(iii) specifies that eligibility changes 
``affecting enrollment or premiums only'' must be effective on the 
first day of the month following the date ``the Exchange is notified of 
the change.'' Under our proposed restructure of Sec.  155.330(f), we 
propose that all enrollee-reported changes, including those affecting 
enrollment or premiums only, would be subject to the effective dates 
under proposed Sec.  155.330(f)(1) and therefore would generally be 
effective on the first of the next month following the eligibility 
determination. For Exchanges on the Federal platform, we clarify that 
even if a reported change only affects enrollment or premiums, an 
Exchange generally also redetermines an enrollee's eligibility for 
enrollment in a QHP and for APTC and CSRs, as applicable, before 
sending an updated transaction to the enrollee's issuer. We request 
comment from State Exchanges regarding whether State Exchanges also 
redetermine enrollees' eligibility in cases in which a reported change 
only affects enrollment or premiums, such that proposed Sec.  
155.330(f)(1) would apply. We also note that Sec.  155.400(b)(1) 
requires Exchanges to send all eligibility and enrollment information, 
which includes updates on eligibility and enrollment, to issuers 
``promptly and without undue delay.''
(ii) Proposal to No Longer Allow Exchanges To Delay Effective Dates for 
Enrollee-Reported Changes
    Current Sec.  155.330(f)(2) provides an exception to current Sec.  
155.330(f)(1), permitting Exchanges to delay the effective dates of 
eligibility redeterminations by one month if they occur on or after the 
15th of a month. For example, if an enrollee reported a change in 
income to an Exchange and an Exchange redetermined the enrollee's 
eligibility for APTC and CSRs on May 20, an Exchange could delay the 
effective date of the resulting APTC and CSR change from June 1, as 
prescribed under the general rule at current Sec.  155.330(f)(1), to 
July 1, as permitted in current Sec.  155.330(f)(2). In proposed Sec.  
155.330(f)(1), we propose that Exchanges would no longer be permitted 
to delay the effective dates for eligibility redeterminations resulting 
from enrollee-reported changes in the manner allowed by current Sec.  
155.330(f)(2). As proposed at Sec.  155.330(f)(1), all eligibility 
redeterminations resulting from enrollee-reported changes would be 
effective the first of the month following an Exchange's 
redetermination, with limited exceptions for scenarios where the 
enrollee also qualifies for certain SEPs. As a result, in the example 
described previously, a change in eligibility for APTC and CSRs 
resulting from an enrollee reporting a change to their income on May 20 
would be effective on June 1, and Exchanges would not be permitted to 
delay the effective date for such changes to July 1.
    We propose to no longer allow the exception currently at Sec.  
155.330(f)(2) for eligibility redeterminations following enrollee-
reported changes for several reasons. First, the redeterminations 
discussed in proposed Sec.  155.330(f)(1) would be limited to enrollee-
reported changes, where the enrollee is actively engaging with the 
Exchange. They would not apply to determinations as part of the 
periodic data matching process or following the expiration of an 
inconsistency period, where the Exchange is redetermining eligibility 
without the enrollee's active engagement. When an enrollee reports a 
change to the Exchange, the enrollee is typically informed of the 
results of their redetermination in real-time, and there is therefore 
no compelling need to delay the effective date of the redetermination 
to ensure that an Exchange is able to communicate with the enrollee 
regarding the change before it takes effect.
    Second, the elimination of the limitations on repayment of excess 
APTC starting in PY 2026, required by section 71305 of the WFTC 
legislation, makes it even more important that Exchanges apply the 
changes that enrollees report without delay, to reduce the risk that 
consumers who accurately report changes to the Exchanges are faced with 
increased tax liability despite their efforts to proactively report 
changes. We seek comment on the proposal to remove the exception 
currently at Sec.  155.330(f)(2) regarding eligibility redeterminations 
following enrollee-reported changes.
    Similarly, for redeterminations resulting from enrollee-reported 
changes, we are proposing to remove Sec.  155.330(f)(3), which provides 
that if a change results in decreased APTC or a change in CSR 
eligibility, and the redetermination occurs after the 15th of a month, 
Exchanges are required to delay the effective date of such eligibility 
redeterminations by one month. For example, if an enrollee reports an 
increase in income to an Exchange and the Exchange determines on May 20 
that the enrollee is eligible for less APTC, an Exchange is required to 
delay the effective date of the resulting decrease in APTC from June 1, 
as prescribed under the general rule at current Sec.  155.330(f)(1), to 
July 1, as required by the exception in current Sec.  155.330(f)(3). 
For enrollee-reported changes, we are proposing to remove the required 
delay at Sec.  155.330(f)(3) for the same reasons we are proposing to 
remove the option for Exchanges to delay under Sec.  155.330(f)(2). For 
redeterminations not resulting from enrollee-reported changes--
specifically, those resulting from the expiration of an inconsistency 
period or periodic data matching--we propose to maintain the required 
delay for redeterminations that result in a decreased amount of APTC or 
decreased level of CSR. This proposal is discussed in detail in section 
III.A.6.c. of this proposed rule.
    We considered proposing an alternative under which Exchanges would 
be required or permitted to immediately implement eligibility 
redeterminations resulting from enrollee-reported changes. However, we 
determined that immediate, mid-month adjustment of APTC and CSRs would 
be more difficult for Exchanges and issuers to implement. Changes to 
APTC and CSR amounts in the middle of a month would require Exchanges 
and issuers to prorate both APTC and premium amounts and would require 
issuers to retroactively re-bill consumers for the month in which the 
change was reported. For these reasons, we are proposing at Sec.  
155.330(f)(1) that eligibility redeterminations resulting

[[Page 67678]]

from enrollee-reported changes become effective on the first of the 
month following an Exchange's redetermination.
(iii) Enrollee-Reported Changes Resulting in an SEP
    Current Sec.  155.330(f)(4) provides another exception to current 
Sec.  155.330(f)(1), requiring that eligibility redeterminations 
associated with an SEP due to gaining or becoming a dependent through 
birth, adoption, foster care, child support, or court order, as 
described at Sec.  155.420(b)(2)(i), become effective on the SEP 
effective dates prescribed in Sec.  155.420(b)(2)(i). We are proposing 
to maintain this exception at proposed Sec.  155.330(f)(1)(i). This 
exception ensures that if, for example, an enrollee adds a newborn to 
their application, the resulting redetermination of the enrollee's 
eligibility due to their change in family size is effective retroactive 
to the newborn's date of birth.
    Current Sec.  155.330(f)(4) further provides that eligibility 
redeterminations associated with an SEP due to marriage become 
effective on the SEP effective dates prescribed in Sec.  
155.420(b)(2)(ii). We are not proposing to maintain this exception in 
proposed Sec.  155.330(f)(1)(i), because Sec.  155.420(b)(2)(ii) 
requires that coverage selected in accordance with an SEP due to 
marriage becomes effective on the first of the month following plan 
selection. Therefore, for consumers with a marriage SEP, their coverage 
effective date already generally aligns with the effective dates for 
eligibility redeterminations proposed at Sec.  155.330(f)(1).
    Current Sec.  155.330(f)(5) provides an exception to current Sec.  
155.330(f)(1) such that eligibility changes associated with an SEP 
described in Sec.  155.420(d)(4), (d)(5), and (d)(9) may be effective 
``based on the specific circumstances of each situation.'' The SEP at 
Sec.  155.420(d)(4) is for qualified individuals who experience an 
error of the Exchange; the SEP at Sec.  155.420(d)(5) is for enrollees 
whose QHP violates a material provision of its contract with the 
enrollee; and the SEP at Sec.  155.420(d)(9) is for qualified 
individuals who experience an exceptional circumstance. In proposed 
Sec.  155.330(f)(1)(i), we are proposing that if an Exchange determines 
that an enrollee qualifies for any of the SEPs enumerated in Sec.  
155.420(b)(2)(iii)--which include the SEPs described at Sec.  
155.420(d)(4), (d)(5), and (d)(9)--then the enrollee's eligibility 
redetermination would be effective on the coverage effective date 
prescribed by Sec.  155.420(b)(2)(iii). Section 155.420(b)(2)(iii) 
provides that the Exchange ``must ensure that coverage is effective on 
an appropriate date based on the circumstances of the special 
enrollment period.'' Therefore, we are proposing to maintain the 
flexibility currently permitted under Sec.  155.330(f)(5) for Exchanges 
to establish appropriate eligibility redetermination effective dates 
for enrollees who qualify for these SEPs.
    We are newly proposing that an Exchange follow the same eligibility 
redetermination effective date rules for an individual eligible for the 
three other SEPs enumerated in Sec.  155.420(b)(2)(iii): the SEP at 
Sec.  155.420(d)(11) for qualified individuals who are determined 
ineligible for Medicaid or CHIP after their enrollment period has 
ended; the SEP at Sec.  155.420(d)(12) for enrollees whose enrollment 
was influenced by a material error regarding certain plan 
characteristics; and the optional SEP at Sec.  155.420(d)(13) for 
individuals who resolve an inconsistency after their QHP has been 
terminated. We do not see a compelling reason to impose different 
eligibility redetermination effective date rules for enrollees with 
these SEPs as compared to the SEPs at Sec.  155.420(d)(4), (d)(5), and 
(d)(9), given that Exchanges have the discretion to establish 
appropriate coverage effective dates for all of these SEPs under Sec.  
155.420(b)(2)(iii). Because Sec.  155.330(f)(5) was finalized prior to 
these SEPs being established, we are of the view that the lack of 
reference to these SEPs at Sec.  155.330(f)(5) is merely an oversight.
    We seek comment on this proposal. Specifically, we seek comment 
from State Exchanges and other interested parties regarding any 
operational burden these proposed changes to current effective date 
policies would create, and whether a 1-year delay in implementation 
would mitigate any expected risk of State Exchanges having insufficient 
time to make necessary updates to their IT systems.
b. Effective Dates Related to the Resolution of DMIs (Sec.  
155.330(f)(2))
    In section III.A.4.b.iv. of this proposed rule and at proposed 
Sec.  155.315(f)(4)(iv)(A), we propose effective date rules for APTC 
and CSR determinations resulting from the resolution of DMIs described 
in Sec. Sec.  155.315(f)(4)(ii) and 155.315(f)(4)(iii)(A) for 
individuals who are enrolled in a QHP when such DMIs are resolved. In 
Sec.  155.330(f)(2), we propose to cross-reference the effective dates 
proposed in Sec.  155.315(f)(4)(iv)(A), such that the same effective 
date rules proposed in Sec.  155.315(f)(4)(iv)(A) would apply for 
individuals described in Sec.  155.330--that is, QHP enrollees whose 
eligibility is redetermined during the coverage year due to the 
resolution of such DMIs.
    Specifically, as proposed at Sec.  155.315(f)(4)(iv)(A), for 
individuals who are enrolled in a QHP when their DMIs are resolved, any 
changes to the eligibility or amount of APTC or CSRs resulting from the 
DMI resolution would be effective on the first day of the first month 
in which all of the following criteria are met: all information related 
to the applicant's DMIs are verified for the month; the enrollee is 
enrolled in a QHP on the first day of the month; and the enrollee's 
DMIs were generated before the first of such month. We further propose 
an exception to these rules in cases where they would result in an 
Exchange determining or redetermining APTC eligibility for months in a 
prior coverage year.
    We propose to align the effective dates proposed in Sec.  
155.330(f)(2) with those described at proposed Sec.  
155.315(f)(4)(iv)(A) for the following reasons.
    Section III.A.4.b.iv. of this proposed rule and proposed Sec.  
155.315(f)(4)(iv)(A)(1) provide that an Exchange's determination of 
APTC or CSR eligibility upon DMI resolution would not be effective 
prior to the first day of the first month for which the Exchange 
verified all eligibility criteria described in proposed Sec.  
155.315(f)(4)(ii). In section III.A.4.b.iv. of this proposed rule, we 
explain that this proposal implements the requirement in section 
36B(c)(5)(C) of the Code, which specifies that a month beginning prior 
to verification must only be considered a coverage month if the 
Exchange verifies the consumer's eligibility ``for such month.'' We 
propose to apply the same principle for enrollees who resolve a DMI 
described at Sec.  155.315(f)(4)(ii) or Sec.  
155.315(f)(4)(iv)(iii)(A), such that any redetermination of APTC or CSR 
eligibility resulting from such DMI resolution does not take effect 
prior to the first month in which the enrollee's newly attested 
eligibility criteria are verified. This proposal ensures equitable 
treatment of new and existing enrollees regarding when their APTC and 
CSRs can begin or increase following DMI resolution.
    Section III.A.4.b.iv. of this proposed rule and proposed Sec.  
155.315(f)(4)(iv)(A)(2) further provide that an Exchange's 
determination of APTC or CSR eligibility upon DMI resolution would not 
be effective prior to the first day of the first month that the 
enrollee is enrolled in a QHP. In

[[Page 67679]]

section III.A.4.b.iv. of this proposed rule, we explain that allowing 
retroactive APTC or CSRs to extend further would produce illogical 
outcomes given that section 36B(c)(2)(A)(i) of the Code requires that a 
taxpayer or their family member must be enrolled in a QHP as of the 
first of the month for the month to be considered a coverage month. 
With regard to the enrollees described in this section, we have 
similarly determined that allowing redeterminations of APTC or CSR 
eligibility to take effect prior to QHP enrollment is illogical and 
should be prevented.
    Section III.A.4.b.iv. of this proposed rule and proposed Sec.  
155.315(f)(4)(iv)(A)(3) provide that an Exchange's determination of 
APTC or CSR eligibility upon DMI resolution would not be effective 
prior to when the consumer's DMIs were generated. We explain in section 
III.A.4.b.iv. of this proposed rule that this proposal aligns with 
Exchanges' existing effective date framework, under which changes to 
eligibility are generally implemented prospectively, in relation to 
when the consumer provides the attestations that produce such changes 
in eligibility. This existing principle also applies to 
redeterminations described in this section.
    Finally, in section III.A.4.b.iv. of this proposed rule and at 
proposed Sec.  155.315(f)(4)(iv)(A)(4), we describe an exception to the 
effective date rules proposed at Sec.  155.315(f)(4)(iv)(A)(1) through 
(3). Specifically, if these rules would result in an APTC effective 
date in the prior coverage year, we propose that the Exchange would not 
provide or increase APTC for those months in the prior year. This 
exception is intended to mitigate tax administration issues and 
consumer burden that would result if Exchanges provided APTC for a 
month after the Exchange had already generated a consumer's Form 1095-A 
for the coverage year. These tax administration issues pertain to both 
initial eligibility determinations and to the redeterminations 
described in this section. Therefore, we are proposing to adopt the 
same rules for APTC and CSR redeterminations for QHP enrollees whose 
eligibility is redetermined during the coverage year due to the 
resolution of their DMIs.
    We seek comment on this proposal.
c. Effective Dates for Redeterminations Following Expiration of 
Inconsistency Period or Periodic Data Matching (Sec.  155.330(f)(3))
    In Sec.  155.330(f)(3), we propose effective date rules for 
eligibility redeterminations following the expiration of an 
inconsistency period or as part of the periodic data matching process 
described at Sec.  155.330(e)(2). Currently, these rules are primarily 
enumerated in Sec.  155.330(f)(3), which covers redeterminations that 
result in a decreased amount of APTC, or a change in the level of CSRs. 
We clarify that current Sec.  155.330(f)(3) also applies in cases where 
an enrollee is redetermined newly ineligible for QHP, APTC, or CSRs. 
While current Sec.  155.330(f)(3) does not explicitly refer to the end 
of an inconsistency period or periodic data matching processes, these 
situations are covered under Sec.  155.330(f)(3) because they generally 
result in the removal or reduction of APTC.
    Current regulations at Sec.  155.330(f)(3) provide that such 
decreases in amount of APTC or in the level of CSRs must be effective 
the first of the month following the redetermination, unless the 
redetermination occurs after the 15th of the month, in which case the 
Exchange must delay the effective date by one month. At Sec.  
155.330(f)(3)(i), we are proposing to maintain these effective date 
rules in cases where an eligibility redetermination is the result of an 
inconsistency period expiring or a periodic data matching process 
ending, and such redetermination results in a decreased amount of APTC 
or decreased level of CSRs.
    Consider an example in which an enrollee is found, through the 
periodic data matching process described in Sec.  155.330(e)(2), to be 
enrolled in other MEC, and in which an Exchange notifies the enrollee 
regarding this updated information on May 20. In accordance with Sec.  
155.330(e)(2)(i)(B), an Exchange provides the enrollee with 30 days, or 
until June 19, to respond to their notice. If the enrollee has not 
responded by the end of this 30-day period, an Exchange must 
redetermine the enrollee's eligibility, in which case the enrollee 
would be determined ineligible for APTC because they are enrolled in 
other MEC. Under current Sec.  155.330(f)(3), because this eligibility 
redetermination results in a decrease in APTC and occurs on June 19, 
the eligibility redetermination must be effective on August 1. Under 
proposed Sec.  155.330(f)(3)(i), this rule would be maintained, and the 
eligibility determination would also be effective on August 1.
    We also propose to maintain the rules currently at Sec.  
155.330(f)(3) for eligibility redeterminations following the end of an 
inconsistency period, where the redetermination results in decreased 
APTC or a decreased level of APTC or CSRs. In a similar example where 
an enrollee's 90-day inconsistency period expires on June 19, the 
resulting eligibility determination would continue to be effective on 
August 1.
    We are proposing to keep these rules for several reasons. First, 
unlike cases where a consumer is reporting updated information to the 
Exchange, consumers whose APTC or CSRs are redetermined following the 
end of an inconsistency period or as part of the periodic data matching 
process are not actively engaged with the Exchange. Therefore, a delay 
between any reduction to the consumer's APTC or level of CSRs and the 
effective date of that redetermination is appropriate to give the 
Exchange sufficient time to communicate the upcoming change in 
eligibility to the consumer. Second, section 71303 of the WFTC 
legislation does not require Exchanges to update existing effective 
date rules for inconsistency period expiration or periodic data 
matching processes or to implement such redeterminations as soon as 
possible.
    Finally, we have determined that maintaining these existing rules 
is operationally simpler for Exchanges than requiring a change to 
existing policy and operations. We acknowledge that the proposals in 
this rule would require Exchanges to make significant changes to their 
systems on a short timeline to meet statutory deadlines. To increase 
the likelihood that Exchanges can successfully implement the many 
changes already required by the WFTC legislation and that would be 
required by this proposed rule, and for the other reasons stated above, 
we propose to maintain the existing effective date policy with regard 
to periodic data matching and DMI expirations that result in a 
reduction in APTC or CSRs.
    There are cases in which the expiration of an inconsistency period 
may instead result in the Exchange determining a consumer eligible for 
the same or an increased amount of APTC, or the same or a more generous 
level of CSRs. In accordance with Sec.  155.315(f)(5), at the end of an 
inconsistency period, if an Exchange remains unable to verify an 
attestation, an Exchange must determine a consumer's eligibility based 
on information available from trusted data sources. In the case that 
the Exchange obtains income data from the Department of Treasury, as 
described in Sec.  155.320(c)(1)(i) and (ii), but such data does not 
verify the consumer's attestation of their income, the Exchange must 
determine eligibility based on this data at the end of the consumer's 
inconsistency period. Depending on the consumer's income attestation 
and the data available to the

[[Page 67680]]

Exchange from the Department of Treasury, this could result in the 
Exchange determining the consumer eligible for more APTC or a more 
generous level of CSRs than provided during their inconsistency period. 
Currently, such redeterminations are subject to the effective date 
rules in Sec.  155.330(f)(1)(i) and (f)(2). These current rules give 
Exchanges the option to either consider such redeterminations effective 
the first of the month following the date of the redetermination 
notice, or to delay the effective date by a month, if the 
redetermination occurred after the 15th of the month.
    Additionally, given the proposals enumerated in proposed Sec.  
155.315(f)(4)(ii) and (iii), the end of an inconsistency period may 
result in no change to a consumer's APTC or CSR eligibility. For 
example, if a consumer has a DMI related to their enrollment in other 
MEC, and the Exchange determines in accordance with the requirements in 
Sec.  155.315(f)(4)(ii) and (iii) that the enrollee cannot be provided 
with APTC or CSRs during their inconsistency period, then the 
expiration of such inconsistency period simply confirms the consumer's 
ineligibility for APTC or CSRs and does not result in an increase or 
decrease.
    At Sec.  155.330(f)(3)(ii), we propose that, for redeterminations 
following the expiration of an inconsistency period or periodic data 
matching that result in the same or an increased amount or level of 
APTC or CSRs, the Exchange be required to implement such 
redeterminations on the first of the month following the 
redetermination. This maintains the general requirement currently 
enumerated at Sec.  155.330(f)(1) but removes the flexibility for 
Exchanges to delay such effective dates until the first of the 
following month afforded under Sec.  155.330(f)(2).
    We propose these rules regarding redeterminations following the 
expiration of an inconsistency period or periodic data matching that 
result in an increased amount or level of APTC or CSRs for several 
reasons. First, eliminating the flexibility currently permitted under 
Sec.  155.330(f)(2) better ensures timely access to APTC and CSRs for 
eligible consumers. While enrollees in this scenario are not actively 
engaged with the Exchange, we see no reason to delay implementing a 
change that results in the same or more APTC or CSRs. In contrast, for 
a change that results in a decrease of APTC or CSRs, we determined a 
delay would be justified to ensure consumers receive timely notice. In 
addition, proposing to remove the flexibility currently permitted under 
Sec.  155.330(f)(2) for these eligibility redeterminations aligns with 
our proposed effective date rules for enrollee-reported changes, 
described in section III.A.6.a. of this proposed rule, thereby 
promoting a consistent set of rules.
    We seek comment on this proposal.
d. Effective Dates for Appeals (Sec.  155.330(f)(4))
    We are proposing to redesignate current Sec.  155.330(f)(1)(ii), 
regarding effective dates for redeterminations resulting from an appeal 
decision, as proposed Sec.  155.330(f)(4), with some minor wording 
changes. This would maintain the current requirement that, in cases 
where an Exchange redetermines eligibility due to an appeal decision, 
that the change in eligibility must be effective on the date specified 
in the appeal decision.
    We seek comment on this proposal.
7. Annual Eligibility Redetermination (Sec.  155.335)
    We propose to modify the title of this section to ``Annual 
eligibility redetermination and re-enrollment.'' We propose to amend 
Sec.  155.335 by revising Sec.  155.335(a) and (b); removing Sec.  
155.335(c) through (i); redesignating Sec.  155.335(j) as new Sec.  
155.335(c); and removing Sec.  155.335(k) through (n). Current Sec.  
155.335(a) through (i) and (k) through (n) include procedures required 
for an Exchange to annually redetermine eligibility for APTC and CSRs 
using the information previously provided by an enrollee in a QHP for 
the current plan year, or an earlier plan year, along with updated 
information from trusted data sources, when the enrollee does not 
contact the Exchange during the annual OEP to update their eligibility 
information. We are proposing to no longer permit these procedures.
    Proposed Sec.  155.335(a) would require Exchanges to redetermine 
the eligibility of an enrollee for enrollment in a QHP and for APTC and 
CSRs, as applicable, on an annual basis in accordance with Sec.  
155.305 and adhere to the existing notification standard for 
eligibility determinations under Sec.  155.310(g). Proposed Sec.  
155.335(a)(1) would newly specify that for an Exchange to redetermine 
an enrollee eligible for APTC and CSRs for the subsequent plan year, 
the enrollee or the enrollee's application filer would be required to 
provide or confirm household income and family size; U.S. citizenship 
or status as a lawfully present eligible non-citizen, as applicable; 
eligibility for or enrollment in other MEC; and place of residence for 
the subsequent plan year on or after August 1 and no later than 
December 31 of the year preceding the applicable plan year, and the 
Exchange would verify the specified eligibility information using the 
processes in Sec. Sec.  155.315 and 155.320, including the relevant 
provisions in those sections regarding DMIs.
    We propose to modify Sec.  155.335(b) to specify that the annual 
eligibility redetermination of QHP and for APTC and CSRs, as 
applicable, would be effective on the first day of the applicable plan 
year. We propose an exception to this effective date for the 
redetermination of APTC and CSRs in instances where an enrollee has an 
unresolved DMI under Sec.  155.315(f)(4)(ii) as of December 31 of the 
year preceding the plan year and for whom APTC and CSRs are not 
provided during the inconsistency period. In these instances, we 
propose that the redetermination of APTC and CSRs under this part take 
effect in accordance with Sec. Sec.  155.315(f)(4)(iv)(A) or 
155.330(f)(3), as applicable.
    Proposed Sec.  155.335(c) would retain the QHP re-enrollment 
standards currently at Sec.  155.335(j). We also clarify that under 
Sec.  155.1200(b)(2), State Exchanges would still be required to submit 
information annually to HHS for HHS oversight on operations regarding 
Sec.  155.335.
    Section 71303(a) of the WFTC legislation specifically states that 
the applicable enrollment information must be ``provided or verified'' 
by the individual and that, generally, the term coverage month does not 
include months ``before the Exchange verifies'' that information. As 
described previously, PTC is allowed only for months that are coverage 
months. Eligibility for PTC is determined after the end of each tax 
year, based on information, such as household income and family size, 
relating to the year of coverage. As a result, section 36B(c)(5)(A) of 
the Code, as added by s
