I. Executive Summary

    We are proposing changes to the provisions and parameters 
implemented through prior rulemaking to implement the ACA.\1\ These 
proposed requirements are published under the authority granted to the 
Secretary by the ACA and the PHS Act.\2\ In this proposed rule, we are 
proposing changes related to some of the ACA provisions and parameters 
we previously implemented and are proposing new provisions. Our goal 
with these proposed requirements is providing quality, affordable 
coverage to consumers while minimizing administrative burden and 
ensuring program integrity. The changes proposed in this rule are also 
intended to help advance health equity, mitigate health disparities, 
and alleviate discrimination.
---------------------------------------------------------------------------

    \1\ The Patient Protection and Affordable Care Act (Pub. L. 111-
148) was enacted on March 23, 2010. The Healthcare 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 rulemaking, the two 
statutes are referred to collectively as the ``Patient Protection 
and Affordable Care Act,'' ``Affordable Care Act,'' or ``ACA.''
    \2\ See sections 1301, 1302, 1311, 1312, 1313, 1321, 1331, and 
1343 of the ACA and sections 2718 and 2792 of the PHS Act.
---------------------------------------------------------------------------

II. Background

A. Legislative and Regulatory Overview

    Title I of the Health Insurance Portability and Accountability Act 
of 1996 (HIPAA) added a new title XXVII to the PHS Act to establish 
various reforms to the group and individual health insurance markets.
    These provisions of the PHS Act were later augmented by other laws, 
including the ACA.
    Subtitles A and C of title I of the ACA reorganized, amended, and 
added to the provisions of part A of title XXVII of the PHS Act 
relating to group health plans and health insurance issuers in the 
group and individual markets. The term ``group health plan'' includes 
both insured and self-insured group health plans.
    Section 2718 of the PHS Act, as added by the ACA, generally 
requires health insurance issuers in the group and individual markets 
to submit an annual medical loss ratio (MLR) report to HHS and provide 
rebates to enrollees if the issuers do not achieve specified MLR 
thresholds.
    Section 1301(a)(1)(B) of the ACA directs all issuers of qualified 
health plans (QHPs) to cover the EHB package described in section 
1302(a) of the ACA, including coverage of the services described in 
section 1302(b) of the ACA, adherence to the cost-sharing limits 
described in section 1302(c) of the ACA, and meeting the Actuarial 
Value (AV) levels established in section 1302(d) of the ACA. Section 
2707(a) of the PHS Act, which is effective for plan or policy years 
beginning on or after January 1, 2014, extends the requirement to cover 
the EHB package to non-grandfathered individual and small group health 
insurance coverage, irrespective of whether such coverage is offered 
through an Exchange. In addition, section 2707(b) of the PHS Act 
directs non-grandfathered group health plans to ensure that cost 
sharing under the plan does not exceed the limitations described in 
section 1302(c)(1) of the ACA.
    Section 1302 of the ACA provides for the establishment of an EHB 
package that includes coverage of EHBs (as defined by the Secretary of 
HHS), cost-sharing limits, and AV requirements. The law directs that 
EHBs be equal in scope to the benefits provided under a typical 
employer plan, and that they cover at least the following 10 general 
categories: ambulatory patient services; emergency services; 
hospitalization; maternity and newborn care; mental health and 
substance use disorder services, including behavioral health treatment; 
prescription drugs; rehabilitative and habilitative services and 
devices; laboratory services; preventive and wellness services and 
chronic disease management; and pediatric services, including oral and 
vision care.
    Sections 1302(b)(4)(A) through (D) of the ACA establish that the 
Secretary must define EHB in a manner that: (1) reflects appropriate 
balance among the 10 categories; (2) is not designed in such a way as 
to discriminate based on age, disability, or expected length of life; 
(3) takes into account the health care needs of diverse segments of the 
population; and (4) does not allow denials of EHBs based on age, life 
expectancy, disability, degree of medical dependency, or quality of 
life.
    Section 1302(d) of the ACA describes the various levels of coverage 
based on AV. Consistent with section 1302(d)(2)(A) of the ACA, AV is 
calculated based on the provision of EHB to a standard population. 
Section 1302(d)(3) of the ACA directs the Secretary of HHS to develop 
guidelines that allow for de minimis variation in AV calculations.
    Section 1311(c) of the ACA provides the Secretary the authority to 
issue regulations to establish criteria for the certification of QHPs. 
Section 1311(c)(1)(B) of the ACA requires, among the criteria for 
certification that the Secretary must establish by regulation, that 
QHPs ensure a sufficient choice of providers. Section 1311(d)(4)(A) of 
the ACA requires the Exchange to implement procedures for the 
certification, recertification, and decertification of health plans as 
QHPs, consistent with guidelines developed by the Secretary under 
section 1311(c) of the ACA. Section 1311(e)(1) of the ACA grants the 
Exchange the authority to certify a health plan as a QHP if the health 
plan meets the Secretary's requirements for certification issued under 
section 1311(c) of the ACA, and the Exchange determines that making the 
plan available through the Exchange is in the interests of qualified 
individuals and qualified employers in the State. Section 1311(c)(6)(C) 
of the ACA directs the Secretary of HHS to

[[Page 82310]]

require an Exchange to provide for special enrollment periods and 
section 1311(c)(6)(D) of the ACA directs the Secretary of HHS to 
require an Exchange to provide for a monthly enrollment period for 
Indians, as defined by section 4 of the Indian Health Care Improvement 
Act.
    Section 1311(d)(3)(B) of the ACA permits a State, at its option, to 
require QHPs to cover benefits in addition to EHB. This section also 
requires a State to make payments, either to the individual enrollee or 
to the issuer on behalf of the enrollee, to defray the cost of these 
additional State-required benefits.
    Section 1312(c) of the ACA generally requires a health insurance 
issuer to consider all enrollees in all health plans (except 
grandfathered health plans) offered by such issuer to be members of a 
single risk pool for each of its individual and small group markets. 
States have the option to merge the individual and small group market 
risk pools under section 1312(c)(3) of the ACA.
    Section 1312(e) of the ACA provides the Secretary with the 
authority to establish procedures under which a State may allow agents 
or brokers to (1) enroll qualified individuals and qualified employers 
in QHPs offered through Exchanges and (2) assist individuals in 
applying for advance payments of the premium tax credit (APTC) and 
cost-sharing reductions (CSRs) for QHPs sold through an Exchange.
    Section 1312(f)(1)(B) of the ACA provides that an individual shall 
not be treated as a qualified individual for enrollment in a QHP if, at 
the time of enrollment, the individual is incarcerated, other than 
incarceration pending the disposition of charges.
    Sections 1313 and 1321 of the ACA provide the Secretary with the 
authority to oversee the financial integrity of State Exchanges, their 
compliance with HHS standards, and the efficient and non-discriminatory 
administration of State Exchange activities. Section 1313(a)(5)(A) of 
the ACA provides the Secretary with the authority to implement any 
measure or procedure that the Secretary determines is appropriate to 
reduce fraud and abuse in the administration of the Exchanges. Section 
1321 of the ACA provides for State flexibility in the operation and 
enforcement of Exchanges and related requirements.
    Section 1321(a) of the ACA provides broad authority for the 
Secretary to establish standards and regulations to implement the 
statutory requirements related to Exchanges, QHPs and other components 
of title I of the ACA, including such other requirements as the 
Secretary determines appropriate. When operating an FFE under section 
1321(c)(1) of the ACA, HHS has the authority under sections 1321(c)(1) 
and 1311(d)(5)(A) of the ACA to collect and spend user fees. Office of 
Management and Budget (OMB) Circular A-25 Revised establishes Federal 
policy regarding user fees and specifies that a user charge will be 
assessed against each identifiable recipient for special benefits 
derived from Federal activities beyond those received by the public.
    Section 1321(d) of the ACA provides that nothing in title I of the 
ACA must be construed to preempt any State law that does not prevent 
the application of title I of the ACA. Section 1311(k) of the ACA 
specifies that Exchanges may not establish rules that conflict with or 
prevent the application of regulations issued by the Secretary.
    Section 1331 of the ACA provides States with an option to establish 
a Basic Health Program (BHP). In the States that elect to operate a 
BHP, the BHP makes affordable health benefits coverage available for 
individuals under age 65 with household incomes between 133 percent and 
200 percent of the Federal poverty level (FPL) who are not otherwise 
eligible for Medicaid, the Children's Health Insurance Program (CHIP), 
or affordable employer-sponsored coverage, or for individuals whose 
income is equal to or below 200 percent of FPL but are lawfully present 
non-citizens ineligible for Medicaid. For those States that have 
expanded Medicaid coverage under section 1902(a)(10)(A)(i)(VIII) of the 
Social Security Act (the Act), the lower income threshold for BHP 
eligibility is effectively 138 percent of the FPL due to the 
application of a required 5 percent income disregard in determining the 
upper limits of Medicaid income eligibility (section 1902(e)(14)(I) of 
the Act).
    Section 1343 of the ACA establishes a permanent risk adjustment 
program to provide payments to health insurance issuers that attract 
higher-than-average risk populations, such as those with chronic 
conditions, funded by charges collected from those issuers that attract 
lower-than-average risk populations, thereby reducing incentives for 
issuers to avoid higher-risk enrollees. Section 1343(b) of the ACA 
provides that the Secretary, in consultation with States, shall 
establish criteria and methods to be used in carrying out the risk 
adjustment activities under this section. Consistent with section 
1321(c) of the ACA, the Secretary is responsible for operating the HHS 
risk adjustment program in any State that fails to do so.\3\
---------------------------------------------------------------------------

    \3\ In the 2014 through 2016 benefit years, HHS operated the 
risk adjustment program in every State and the District of Columbia, 
except Massachusetts. Beginning with the 2017 benefit year, HHS has 
operated the risk adjustment program in all 50 States and the 
District of Columbia.
---------------------------------------------------------------------------

    Section 1401(a) of the ACA added section 36B to the Internal 
Revenue Code (the Code), which, among other things, requires that a 
taxpayer reconcile APTC for a year of coverage with the amount of the 
premium tax credit (PTC) the taxpayer is allowed for the year.
    Section 1402 of the ACA provides for, among other things, 
reductions in cost sharing for EHB for qualified low- and moderate-
income enrollees in silver level QHPs offered through the individual 
market Exchanges. This section also provides for reductions in cost 
sharing for Indians enrolled in QHPs at any metal level.
    Section 1411(f) of the ACA requires the Secretary, in consultation 
with the Secretary of the Treasury and the Secretary of Homeland 
Security, and the Commissioner of Social Security, to establish 
procedures for hearing and making decisions governing appeals of 
Exchange eligibility determinations. Section 1411(f)(1)(B) of the ACA 
requires the Secretary to establish procedures to redetermine 
eligibility on a periodic basis, in appropriate circumstances, 
including eligibility to purchase a QHP through the Exchange and for 
APTC and CSRs.
    Section 1411(g) of the ACA allows the use of applicant information 
only for the limited purpose of, and to the extent necessary for, 
ensuring the efficient operation of the Exchange, including by 
verifying eligibility to enroll through the Exchange and for APTC and 
CSRs, and limits the disclosure of such information.
    Section 1413 of the ACA directs the Secretary to establish, subject 
to minimum requirements, a streamlined enrollment process for 
enrollment in QHPs and all insurance affordability programs.
    Section 5000A of the Code, as added by section 1501(b) of the ACA, 
requires individuals to have minimum essential coverage (MEC) for each 
month, qualify for an exemption, or make an individual shared 
responsibility payment. Under the Tax Cuts and Jobs Act, which was 
enacted on December 22, 2017, the individual shared responsibility 
payment is reduced to $0, effective for months beginning after December 
31, 2018. Notwithstanding that reduction, certain exemptions are still 
relevant to determine whether individuals aged 30 and above qualify to 
enroll in

[[Page 82311]]

catastrophic coverage under Sec. Sec.  155.305(h) and 156.155(a)(5).
    Section 1902(r)(2)(A) of the Act permits States to apply less 
restrictive methodologies than cash assistance program methodologies in 
determining eligibility for certain eligibility groups.
1. Premium Stabilization Programs
    The premium stabilization programs refer to the risk adjustment, 
risk corridors, and reinsurance programs established by the ACA.\4\ For 
past rulemaking, we refer readers to the following rules:
---------------------------------------------------------------------------

    \4\ See section 1341 of the ACA (transitional reinsurance

Payment Notice), we finalized the benefit and payment parameters for 
the 2019 benefit year, created the State flexibility framework 
permitting States to request a reduction in risk adjustment State 
transfers calculated by HHS, and adopted a new error rate methodology 
for HHS-RADV adjustments to transfers.
    <bullet> In the May 11, 2018 Federal Register (83 FR 21925), we 
issued a correction to the 2019 HHS risk adjustment coefficients in the 
2019 Payment Notice.
    <bullet> On July 27, 2018, consistent with 45 CFR 153.320(b)(1)(i), 
we updated the 2019 benefit year final HHS risk adjustment model 
coefficients to reflect an additional recalibration related to an 
update to the 2016 enrollee-level EDGE data set.\5\

---------------------------------------------------------------------------

    <bullet> In the July 30, 2018 Federal Register (83 FR 36456), we 
adopted the 2017 benefit year HHS risk adjustment methodology as 
established in the final rules issued in the March 23, 2012 (77 FR 
17220 through 17252) and March 8, 2016 (81 FR 12204 through 12352) 
editions of the Federal Register. The final rule set forth an 
additional explanation of the rationale supporting the use of Statewide 
average premium in the State payment transfer formula for the 2017 
benefit year, including the reasons why the program is operated by HHS 
in a budget-neutral manner. The final rule also permitted HHS to resume 
2017 benefit year HHS risk adjustment payments and charges. HHS also 
provided guidance as to the operation of the HHS-operated risk 
adjustment program for the 2017 benefit year in light of the 
publication of the final rule.
    <bullet> In the December 10, 2018 Federal Register (83 FR 63419), 
we adopted the 2018 benefit year HHS risk adjustment methodology as 
established in the final rules issued in the March 23, 2012 (77 FR 
17219) and the December 22, 2016 (81 FR 94058) editions of the Federal 
Register. In the rule, we set forth an additional explanation of the 
rationale supporting the use of Statewide average premium in the State 
payment transfer formula for the 2018 benefit year, including the 
reasons why the program is operated by HHS in a budget-neutral manner.
    <bullet> In the April 25, 2019 Federal Register (84 FR 17454) (2020 
Payment Notice), we finalized the benefit and payment parameters for 
the 2020 benefit year, as well as the policies related to making the 
enrollee-level EDGE data available as a limited data set for research 
purposes and expanding the HHS uses of the enrollee-level EDGE data, 
approval of the request from Alabama to reduce HHS risk adjustment 
transfers by 50 percent in the small group market for the 2020 benefit 
year, and updates to HHS-RADV program requirements.
    <bullet> On May 12, 2020, consistent with Sec.  153.320(b)(1)(i), 
we issued the 2021 Benefit Year Final HHS Risk Adjustment Model 
Coefficients on the CCIIO website.\6\

---------------------------------------------------------------------------

    <bullet> In the May 14, 2020 Federal Register (85 FR 29164) (2021 
Payment Notice), we finalized the benefit and payment parameters for 
the 2021 benefit year, as well as adopted updates to the HHS risk 
adjustment models' hierarchical condition categories (HCCs) to 
transition to the 10th revision of the International Statistical 
Classification of Diseases (ICD-10) codes, approved the request from 
Alabama to reduce HHS risk adjustment transfers by 50 percent in the 
small group market for the 2021 benefit year, and modified the outlier 
identification process under the HHS-RADV program.
    <bullet> In the December 1, 2020 Federal Register (85 FR 76979) 
(Amendments to the HHS-Operated Risk Adjustment Data Validation Under 
the Patient Protection and Affordable Care Act's HHS-Operated Risk 
Adjustment Program (2020 HHS-RADV Amendments Rule)), we adopted the 
creation and application of Super HCCs in the sorting step that assigns 
HCCs to failure rate groups, finalized a sliding scale adjustment in 
HHS-RADV error rate calculation, and added a constraint

[[Page 82312]]

for negative error rate outliers with a negative error rate. We also 
established a transition from the prospective application of HHS-RADV 
adjustments to apply HHS-RADV results to risk scores from the same 
benefit year as that being audited.
    <bullet> In the September 2, 2020 Federal Register (85 FR 54820), 
we issued an interim final rule containing certain policy and 
regulatory revisions in response to the COVID-19 public health 
emergency (PHE), wherein we set forth HHS risk adjustment reporting 
requirements for issuers offering temporary premium credits in the 2020 
benefit year.
    <bullet> In the May 5, 2021 Federal Register (86 FR 24140) (part 2 
of the 2022 Payment Notice), we finalized a subset of proposals from 
the December 4, 2020 Federal Register (85 FR 78572) (the 2022 Payment 
Notice proposed rule), including policy and regulatory revisions 
related to the HHS-operated risk adjustment program, finalization of 
the benefit and payment parameters for the 2022 benefit year, and 
approval of the request from Alabama to reduce HHS risk adjustment 
transfers by 50 percent in the individual and small group markets for 
the 2022 benefit year. In addition, this final rule established a 
revised schedule of collections for HHS-RADV and updated the provisions 
regulating second validation audit (SVA) and initial validation audit 
(IVA) entities.
    <bullet> On July 19, 2021, consistent with Sec.  153.320(b)(1)(i), 
we released Updated 2022 Benefit Year Final HHS Risk Adjustment Model 
Coefficients on the CCIIO website, announcing some minor revisions to 
the 2022 benefit year final HHS risk adjustment adult model 
coefficients.\7\

---------------------------------------------------------------------------

    <bullet> In the May 6, 2022 Federal Register (87 FR 27208) (2023 
Payment Notice), we finalized revisions related to the HHS-operated 
risk adjustment program, including the benefit and payment parameters 
for the 2023 benefit year, HHS risk adjustment model recalibration, and 
policies related to the collection and extraction of enrollee-level 
EDGE data. We also finalized the adoption of the interacted HCC count 
specification for the adult and child models, along with modified 
enrollment duration factors for the adult models, beginning with the 
2023 benefit year.\8\ We also repealed the ability for States, other 
than prior participants, to request a reduction in HHS risk adjustment 
State transfers starting with the 2024 benefit year. In addition, we 
approved a 25 percent reduction to 2023 benefit year HHS risk 
adjustment transfers in Alabama's individual market and a 10 percent 
reduction to 2023 benefit year HHS risk adjustment transfers in 
Alabama's small group market. We also finalized further refinements to 
the HHS-RADV error rate calculation methodology beginning with the 2021 
benefit year.

---------------------------------------------------------------------------

    <bullet> In the April 27, 2023 Federal Register (88 FR 25740) (2024 
Payment Notice), we finalized the benefit and payment parameters for 
the 2024 benefit year, amended the EDGE discrepancy materiality 
threshold and data collection requirements, and reduced the risk 
adjustment user fee. For the 2024 benefit year, we approved 50 percent 
reductions to HHS risk adjustment transfers for Alabama's individual 
and small group markets, and repealed prior participant States' ability 
to request reductions of their risk adjustment transfers for the 2025 
benefit year and beyond. We finalized several refinements to HHS-RADV 
program requirements, such as shortening the window to confirm SVA 
findings or file a discrepancy report, changing the HHS-RADV 
materiality threshold for random and targeted sampling, and no longer 
exempting exiting issuers from adjustments to risk scores and HHS risk 
adjustment transfers when they are negative error rate outliers. We 
also announced the discontinuance of the Lifelong Permanent Condition 
List (LLPC) and Non-EDGE Claims (NEC) in HHS-RADV beginning with the 
2022 benefit year.
    <bullet> In the April 15, 2024 Federal Register (89 FR 26218) (2025 
Payment Notice), we finalized the benefit and payment parameters for 
the 2025 benefit year, including the 2025 risk adjustment models and 
updated the adjustment factors for the receipt of CSRs for the American 
Indian and Alaska Native (AI/AN) subpopulation who are enrolled in zero 
and limited cost-sharing plans to improve prediction in the HHS risk 
adjustment models. In addition, we finalized that in certain cases, we 
may require a corrective action plan (CAP) to address an observation 
identified in an HHS risk adjustment program audit.
2. Program Integrity
    We have finalized program integrity standards related to the 
Exchanges and premium stabilization programs in two rules: the ``first 
Program Integrity Rule'' issued in the August 30, 2013 Federal Register 
(78 FR 54069), and the ``second Program Integrity Rule'' issued in the 
October 30, 2013 Federal Register (78 FR 65045). We also refer readers 
to the 2019 Patient Protection and Affordable Care Act; Exchange 
Program Integrity final rule (2019 Program Integrity Rule) issued in 
the December 27, 2019 Federal Register (84 FR 71674).
    In the April 27, 2023 Federal Register (88 FR 25740) (2024 Payment 
Notice), we finalized a policy to implement improper payment pre-
testing and assessment (IPPTA) requirements for State Exchanges to 
ensure adherence to the Payment Integrity Information Act of 2019. In 
addition, we finalized allowing additional time for HHS to review 
evidence submitted by agents and brokers to rebut allegations 
pertaining to Exchange agreement suspensions or terminations. We also 
introduced consent and eligibility application documentation 
requirements for agents, brokers, and web-brokers that assist Exchange 
consumers in FFE and SBE-FP States.
3. Market Rules
    In the February 27, 2013 Federal Register (78 FR 13406), we issued 
the health insurance market rules, including provisions related to the 
single risk pool. We amended requirements related to index rates under 
the single risk pool provision in a final rule issued in the July 2, 
2013 Federal Register (78 FR 39870). In the October 30, 2013 Federal 
Register (78 FR 65046), we clarified when issuers may establish and 
update premium rates. In the March 8, 2016 Federal Register (81 FR 
12203), we clarified single risk pool provisions related to student 
health insurance coverage. We finalized minor adjustments to the single 
risk pool regulations in the 2018 Payment Notice, issued in the 
December 22, 2016 Federal Register (81 FR 94058).
4. Exchanges
    We issued a request for comment relating to Exchanges in the August 
3, 2010 Federal Register (75 FR 45584). We issued initial guidance to 
States on Exchanges on November 18, 2010. In the March 27, 2012 Federal 
Register (77 FR 18310) (Exchange Establishment Rule), we implemented 
the Affordable Insurance Exchanges (Exchanges), consistent with title I 
of the ACA, to provide competitive marketplaces for individuals and 
small employers to directly compare available private health insurance 
options on the basis of price, quality, and other factors. This

[[Page 82313]]

included implementation of components of the Exchanges and standards 
for eligibility for Exchanges, as well as network adequacy and 
essential community provider (ECP) certification standards.
    In the August 17, 2011 Federal Register (76 FR 51201), we issued a 
proposed rule regarding eligibility determinations, including the 
regulatory requirement to verify incarceration status. In the March 27, 
2012 Federal Register (77 FR 18310) we finalized the regulatory 
requirement to verify incarceration attestation using an approved 
electronic data source that is current and accurate, and to resolve the 
inconsistency when attestations are not reasonably compatible with 
information in an approved data source. We also established 
requirements regarding accessible communications for individuals with 
disabilities and those with LEP.
    In the 2014 Payment Notice and the Amendments to the HHS Notice of 
Benefit and Payment Parameters for 2014 interim final rule, issued in 
the March 11, 2013 Federal Register (78 FR 15541), we set forth 
standards related to Exchange user fees. We established an adjustment 
to the FFE user fee in the Coverage of Certain Preventive Services 
under the Affordable Care Act final rule, issued in the July 2, 2013 
Federal Register (78 FR 39869) (Preventive Services Rule).
    In the 2016 Payment Notice, we also set forth the ECP certification 
standard at Sec.  156.235, with revisions in the 2017 Payment Notice in 
the March 8, 2016 Federal Register (81 FR 12203) and the 2018 Payment 
Notice in the December 22, 2016 Federal Register (81 FR 94058).
    In the 2018 Payment Notice, issued in the December 22, 2016 Federal 
Register (81 FR 94058), we set forth the standards for the request for 
reconsideration of denial of certification specific to the FFEs at 
Sec.  155.1090.
    In an interim final rule, issued in the May 11, 2016 Federal 
Register (81 FR 29146), we made amendments to the parameters of certain 
special enrollment periods (2016 Interim Final Rule). We finalized 
these in the 2018 Payment Notice, issued in the December 22, 2016 
Federal Register (81 FR 94058).
    In the Market Stabilization final rule, issued in the April 18, 
2017 Federal Register (82 FR 18346), we amended standards relating to 
special enrollment periods and QHP certification. In the 2019 Payment 
Notice, issued in the April 17, 2018 Federal Register (83 FR 16930), we 
modified parameters around certain special enrollment periods. In the 
April 25, 2019 Federal Register (84 FR 17454), the 2020 Payment Notice 
established a new special enrollment period.
    In the May 14, 2020 Federal Register (85 FR 29164) (2021 Payment 
Notice), we finalized revisions to the parameters of special enrollment 
periods and the quality rating information display standards for State 
Exchanges and amended the periodic data matching requirements.
    In the January 19, 2021 Federal Register (86 FR 6138) (part 1 of 
the 2022 Payment Notice), we finalized only a subset of the proposals 
in the 2022 Payment Notice proposed rule. In the May 5, 2021 Federal 
Register (86 FR 24140), we issued part 2 of the 2022 Payment Notice. In 
part 3 of the 2022 Payment Notice, issued in the September 27, 2021 
Federal Register (86 FR 53412), in conjunction with the Department of 
the Treasury, we finalized amendments to certain policies in part 1 of 
the 2022 Payment Notice.
    In the May 6, 2022 Federal Register (87 FR 27208), we finalized 
changes to maintain the user fee rate for issuers offering plans 
through the FFEs and maintain the user fee rate for issuers offering 
plans through the SBE-FPs for the 2023 benefit year. We also finalized 
various policies to address certain agent, broker, and web-broker 
practices and conduct. We also finalized updates to the requirement 
that all Exchanges conduct special enrollment period verifications.
    In the 2024 Payment Notice, issued in the April 27, 2023 Federal 
Register (88 FR 25740), we revised Exchange Blueprint approval 
timelines, lowered the user fee rate for QHPs in the FFEs and SBE-FPs, 
and amended re-enrollment hierarchies for enrollees. We also finalized 
policies to update FFE and SBE-FP standardized plan options; reduced 
the risk of plan choice overload on the FFEs and SBE-FPs by limiting 
the number of non-standardized plan options that issuers may offer 
through Exchanges on the Federal platform to four for PY 2024 and to 
two for PY 2025 and subsequent years; and ensure correct QHP 
information. In addition, we amended coverage effective date rules, 
lengthened the special enrollment period from 60 to 90 days for those 
who lose Medicaid coverage, and prohibited QHPs on FFEs and SBE-FPs 
from terminating coverage mid-year for dependent children who reach the 
applicable maximum age. We also finalized policies on verifying 
consumer income and permitting door-to-door assisters to solicit 
consumers. To ensure provider network adequacy, we finalized provider 
network and ECP policies for QHPs. We revised the failure to file and 
reconcile process to ensure enrollees would not lose APTC eligibility 
until they or their tax filer failed to file their Federal income taxes 
and reconcile APTC for two consecutive tax years.
    In the 2025 Payment Notice, issued in the April 15, 2024 Federal 
Register (89 FR 26218), we required a State seeking to operate a State 
Exchange to first operate an SBE-FP for at least one plan year, revised 
Exchange Blueprint requirements for States transitioning to a State 
Exchange, established additional minimum standards for Exchange call 
center operations, required an Exchange to operate a centralized 
eligibility and enrollment platform on its website, and finalized 
various policies for web-brokers and direct enrollment entities. In 
addition, we required State Exchanges and State Medicaid agencies to 
remit payment to HHS for their use of certain income data, amended re-
enrollment hierarchies for enrollees enrolled in catastrophic coverage, 
revised the parameters around a State Exchange adopting an alternative 
open enrollment period, and extended the availability of a special 
enrollment period for APTC-eligible qualified individuals with a 
projected annual household income no greater than 150 percent of the 
Federal Poverty Level (FPL). To ensure provider network adequacy in 
State Exchanges and SBE-FPs, we finalized provider network adequacy 
policies applicable to such Exchanges for PY 2026 and subsequent plan 
years. We also further lowered the user fee rate for QHPs in the FFEs 
and SBE-FPs. In addition, we finalized the policy to maintain FFE and 
SBE-FP standardized plan option metal levels from the 2024 Payment 
Notice and finalized an exceptions process to the limitation on non-
standardized plan options in FFEs and SBE-FPs. We also finalized the 
requirement for Exchanges to provide notification to enrollees or their 
tax filers who have failed to file their Federal income taxes and 
reconcile APTC for one tax year.
5. Essential Health Benefits
    We established requirements relating to EHBs in the Standards 
Related to Essential Health Benefits, Actuarial Value, and 
Accreditation Final Rule, which was issued in the February 25, 2013 
Federal Register (78 FR 12834) (EHB Rule). We established at Sec.  
156.135(a) that AV is generally to be calculated using the AV 
Calculator developed and made available by HHS for a given benefit 
year. In the 2015 Payment Notice (79 FR 13743), we established at Sec.  
156.135(g) provisions

[[Page 82314]]

for updating the AV Calculator in future plan years. In the 2017 
Payment Notice (81 FR 12349), we amended the provisions at Sec.  
156.135(g) to allow for additional flexibility in our approach and 
options for updating of the AV Calculator.
    In the 2025 Payment Notice, issued in the April 15, 2024 Federal 
Register (89 FR 26218), we revised Sec.  155.170(a) to codify that 
benefits covered in a State's EHB-benchmark plan are not considered in 
addition to EHB, even if they had been required by State action taking 
place after December 31, 2011, other than for purposes of compliance 
with Federal requirements. We finalized three revisions to the 
standards for State selection of EHB-benchmark plans for benefit years 
beginning on or after January 1, 2026: we revised the typicality 
standard at Sec.  156.111 for States to demonstrate that their new EHB-
benchmark plan provides a scope of benefits that is equal to that of a 
typical employer plan in the State and removed the generosity standard; 
removed the requirement for States to submit a formulary drug list as 
part of their application unless they are changing their prescription 
drug EHBs; and consolidated the options for States to change their EHB-
benchmark plans. We also removed the regulatory prohibition at Sec.  
156.115(d) on issuers from including routine non-pediatric dental 
services as an EHB beginning with PY 2027. In addition, we revised 
Sec.  156.122 to codify that prescription drugs in excess of those 
covered by a State's EHB-benchmark plan are considered EHB. We also 
stated that HHS and the Departments of Labor and the Treasury intend to 
propose rulemaking that would align the standards applicable to large 
group market health plans and self-insured group health plans with 
those applicable to individual and small group market plans, so that 
all group health plans and health insurance coverage subject to 
sections 2711 and 2707(b) of the PHS Act, as applicable, would be 
required to treat prescription drugs covered by the plan or coverage in 
excess of the applicable EHB-benchmark plan as EHB for purposes of the 
prohibition of lifetime and annual limits and the annual limitation on 
cost sharing, which would further strengthen the consumer protections 
in the ACA.
6. Medical Loss Ratio (MLR)
    We issued a request for comment on section 2718 of the PHS Act in 
the April 14, 2010 Federal Register (75 FR 19297) and issued an interim 
final rule with a 60-day comment period relating to the MLR program on 
December 1, 2010 (75 FR 74864). A final rule with a 30-day comment 
period was issued in the December 7, 2011 Federal Register (76 FR 
76573). An interim final rule with a 60-day comment period was issued 
in the December 7, 2011 Federal Register (76 FR 76595). A final rule 
was issued in the Federal Register on May 16, 2012 (77 FR 28790). The 
MLR program requirements were amended in final rules issued in the 
March 11, 2014 Federal Register (79 FR 13743), the May 27, 2014 Federal 
Register (79 FR 30339), the February 27, 2015 Federal Register (80 FR 
10749), the March 8, 2016 Federal Register (81 FR 12203), the December 
22, 2016 Federal Register (81 FR 94183), the April 17, 2018 Federal 
Register (83 FR 16930), the May 14, 2020 Federal Register (85 FR 
29164), the May 5, 2021 Federal Register (86 FR 24140), and the May 6, 
2022 Federal Register (87 FR 27208), and an interim final rule that was 
issued in the September 2, 2020 Federal Register (85 FR 54820).
7. Quality Improvement Strategy
    We issued regulations in Sec.  155.200(d) to direct Exchanges to 
evaluate quality improvement strategies, and Sec.  156.200(b) to direct 
QHP issuers to implement and report on a quality improvement strategy 
or strategies consistent with section 1311(g) standards as QHP 
certification criteria for participation in an Exchange. In the 2016 
Payment Notice, issued in the February 27, 2015 Federal Register (80 FR 
10749), we finalized regulations at Sec.  156.1130 to establish 
standards and the associated timeframe for QHP issuers to submit the 
necessary information to implement quality improvement strategy 
standards for QHPs offered through an Exchange.
8. Basic Health Program
    In the March 12, 2014, Federal Register (79 FR 14111), we issued a 
final rule entitled the ``Basic Health Program: State Administration of 
Basic Health Programs; Eligibility and Enrollment in Standard Health 
Plans; Essential Health Benefits in Standard Health Plans; Performance 
Standards for Basic Health Programs; Premium and Cost Sharing for Basic 
Health Programs; Federal Funding Process; Trust Fund and Financial 
Integrity'' (hereinafter referred to as the BHP final rule) 
implementing section 1331 of the ACA, which governs the establishment 
of BHPs. The BHP final rule established the standards for State and 
Federal administration of BHPs, including provisions regarding 
eligibility and enrollment, benefits, cost-sharing requirements and 
oversight activities. In the BHP final rule, we specified that the BHP 
Payment Notice process would include the annual publication of both a 
proposed and final BHP payment methodology.
    On October 11, 2017, the Attorney General of the United States 
provided HHS and the Department of the Treasury (the Departments) with 
a legal opinion \9\ indicating that the permanent appropriation at 31 
U.S.C. 1324, from which the Departments had historically drawn funds to 
make CSR payments, cannot be used to fund CSR payments to insurers. In 
light of this opinion--and in the absence of any other appropriation 
that could be used to fund CSR payments--HHS directed CMS to 
discontinue CSR payments to issuers until Congress provides for an 
appropriation. As a result of this opinion, CMS discontinued CSR 
payments to issuers in the States operating a BHP (that is, New York 
and Minnesota). The States then sued the Secretary for declaratory and 
injunctive relief in the United States District Court for the Southern 
District of New York.\10\ On May 2, 2018, the parties filed a 
stipulation requesting a stay of the litigation so that HHS could issue 
an administrative order revising the 2018 BHP payment methodology. 
After consideration of the States' comments on the administrative order 
revising the payment methodology, we issued a Final Administrative 
Order on August 24, 2018 (Final Administrative Order) setting forth the 
payment methodology that would apply to the 2018 BHP program year.

    In the November 5, 2019 Federal Register (84 FR 59529) (hereinafter 
referred to as the November 2019 final BHP Payment Notice), we 
finalized the payment methodologies for BHP program years 2019 and 
2020.\11\ The 2019 payment methodology is the same payment methodology 
described in the Final Administrative Order. The 2020 payment 
methodology is the same methodology as the 2019 payment methodology 
with one additional adjustment to account for the impact of individuals 
selecting different metal tier level plans in the Exchange, referred to 
as the Metal Tier Selection Factor

(MTSF).\12\ In the August 13, 2020 Federal Register (85 FR 49264) 
(hereinafter referred to as the August 2020 final BHP Payment Notice), 
we finalized the payment methodology for BHP program year 2021. The 
2021 payment methodology is the same methodology as the 2020 payment 
methodology, with one adjustment to the income reconciliation factor 
(IRF). In the July 7, 2021 Federal Register (86 FR 35615) (hereinafter 
referred to as the July 2021 final BHP Payment Notice), we finalized 
the payment methodology for BHP program year 2022. The 2022 payment 
methodology is the same as the 2021 payment methodology, with the 
exception of the removal of the Metal Tier Selection Factor.
---------------------------------------------------------------------------

    \11\ BHP program year means a calendar year for which a standard 
health plan provides coverage for BHP enrollees. See 42 CFR 600.5.
    \12\ ``Metal tiers'' refer to the different actuarial value plan 
levels offered on the Exchanges. Bronze-level plans generally must 
provide 60 percent actuarial value; silver-level 70 percent 
actuarial value; gold-level 80 percent actuarial value; and 
platinum-level 90 percent actuarial value. See 45 CFR 156.140.
---------------------------------------------------------------------------

    In the December 20, 2022 Federal Register (87 FR 77722) (hereafter 
referred to as the 2023 final BHP Payment Notice), we finalized the 
payment methodology for BHP program year 2023. The 2023 payment 
methodology is the same as the 2022 payment methodology, except for the 
addition of a factor to account for a State operating a BHP and 
implementing an approved State Innovation Waiver under section 1332 of 
the ACA; this is the section 1332 waiver factor (WF). In the 2023 final 
BHP Payment Notice (87 FR 77723), we also revised the schedule for 
issuance of payment notices and allowed payment notices to be effective 
for 1 or multiple program years, as determined by and subject to the 
direction of the Secretary, beginning with the 2023 payment 
methodology. In the 2025 Payment Notice, issued in the April 15, 2024 
Federal Register (89 FR 26218), we finalized that States may start BHP 
applicants' effective date of eligibility on the first day of the month 
following the date of application. In addition, we finalized that, 
subject to HHS approval, a State may establish its own effective date 
of eligibility for enrollment policy.

B. Summary of Major Provisions

    The regulations outlined in this proposed rule would be codified in 
42 CFR part 600 and 45 CFR parts 153, 155, 156, and 158.
1. 42 CFR Part 600
    We are proposing changes to the methodology regarding the premium 
adjustment factor (PAF), which is used to calculate the adjusted 
reference premium (ARP) for BHP payment. We propose maintaining the PAF 
value at 1.188 for States that have fully implemented BHP and are using 
Second Lowest Cost Silver Plan (SLCSP) premiums from a year in which 
BHP was fully implemented. As previously clarified, for States in their 
first year of implementing BHP and choosing to use prior year SLCSP 
premiums to determine BHP payment, the PAF value would be set to 1.00. 
We propose that if a State is using SLCSP premiums from a year in which 
BHP was not fully implemented, the PAF is calculated by determining the 
CSR adjustment that QHP issuers included in the SLCSP premiums, 
reporting the CSR adjustments for the SLCSP for each region in the 
State to CMS, and then CMS calculating the PAF as 1.20 divided by 1 
plus the adjustment. Additionally, we are proposing a technical 
clarification for BHP payment rates in cases of multiple SLCSP premiums 
in an area.
2. 45 CFR Part 153
    In accordance with the OMB Report to Congress on the Joint 
Committee Reductions for Fiscal Year 2025, the HHS-operated risk 
adjustment program is subject to the fiscal year 2025 
sequestration.\13\ Therefore, the HHS-operated risk adjustment program 
will sequester payments made from fiscal year 2025 resources (that is, 
funds collected during the 2025 fiscal year) at a rate of 5.7 percent.

---------------------------------------------------------------------------

    We propose to recalibrate the 2026 benefit year HHS risk adjustment 
models using the 2020, 2021, and 2022 benefit year enrollee-level EDGE 
data. Starting with the 2026 benefit year, we propose to begin phasing 
out the market pricing adjustment to the plan liability associated with 
Hepatitis C drugs in the HHS risk adjustment models (see, for example, 
84 FR 17463 through 17466). We also are proposing to incorporate pre-
exposure prophylaxis (PrEP) as a separate, new type of factor called an 
Affiliated Cost Factor (ACF) in the HHS risk adjustment adult and child 
models starting with the 2026 benefit year. We also request information 
on whether the HHS-operated risk adjustment program should take into 
account the time value of money for the collection and remittance of 
State transfers that occur 8 to 10 months after the conclusion of the 
benefit year. We also propose a risk adjustment user fee for the 2026 
benefit year of $0.18 per member per month (PMPM).
    Beginning with the 2025 benefit year of HHS-RADV, we propose to 
exclude enrollees without HCCs, which includes enrollees with only 
prescription drug categories (RXCs), from the IVA sample, remove the 
Finite Population Correction (FPC) from the IVA sampling methodology, 
and replace the source of the Neyman allocation data used for HHS-RADV 
sampling with the most recent 3 years of consecutive HHS-RADV data. In 
addition, beginning with the 2024 benefit year of HHS-RADV, we propose 
to modify the SVA pairwise means test, which tests for statistical 
differences between the IVA and SVA results, to use a bootstrapped 90 
percent confidence interval methodology and to increase the initial SVA 
subsample size from 12 enrollees to 24 enrollees.
3. 45 CFR Part 155
    We seek comment on how assisters who perform their assister duties 
in a hospital and hospital system may, within the bounds of the 
statute, refer consumers to programs designed to reduce medical debt.
    We address our authority to investigate and undertake compliance 
reviews and enforcement actions in response to misconduct or 
noncompliance with applicable agent, broker, and web-broker Exchange 
requirements or standards occurring at the insurance agency level and 
how we intend to hold lead agents of insurance agencies accountable for 
such misconduct or noncompliance.
    We propose to revise Sec.  155.220(k)(3) to reflect our authority 
to suspend an agent's or broker's ability to transact information with 
the Exchange in instances where HHS discovers circumstances that pose 
unacceptable risk to accuracy of Exchange eligibility determinations, 
Exchange operations, applicants, or enrollees, or Exchange information 
technology systems, including but not limited to risk related to 
noncompliance with the standards of conduct under Sec.  
155.220(j)(2)(i), (ii) or (iii) and the privacy and security standards 
under Sec.  155.260, until the circumstances of the incident, breach, 
or noncompliance are remedied or sufficiently mitigated to HHS' 
satisfaction.
    We propose to update the Model Consent Form that agents, brokers, 
and web-brokers can use to obtain and document consumer consent.\14\ 
The

[[Page 82316]]

updates would expand the resource to include a standardized form that 
agents, brokers, and web-brokers can use to document the consumer's 
review and confirmation of the accuracy of information in their 
Exchange eligibility application, which is a new standard of conduct 
that was also implemented as part of the 2024 Payment Notice (88 FR 
25809 through 25814). The proposed updates would also add scripts that 
agents, brokers, and web-brokers could utilize to meet the consumer 
consent and eligibility application review requirements finalized in 
the 2024 Payment Notice via an audio recording. We are not proposing 
any regulatory text changes since the use of the updated Model Consent 
Form would not be mandatory.

---------------------------------------------------------------------------

    We propose to amend Sec.  155.305(f)(4) to require Exchanges to 
provide notice to consumers and tax filers who have failed to file and 
reconcile their APTC for 2 consecutive years.
    We propose to add Sec.  155.400(d)(1) to codify HHS' guidance that 
requires that, within 60 calendar days after a State Exchange receives 
a data inaccuracy from an issuer operating in an State Exchange that 
includes a description of an inaccuracy that meets the requirements at 
Sec.  156.1210(a)-(c) and all the information that the State Exchange 
requires or requests to properly assess the inaccuracy, State Exchanges 
must review and resolve the State Exchange issuer's enrollment data 
inaccuracies and submit to HHS a description of the resolution of any 
inaccuracies described by the State Exchange issuer that the State 
Exchange confirms to be inaccuracies in a format and manner specified 
by HHS.
    We propose to revise Sec.  155.400(g) to allow issuers to adopt a 
fixed-dollar payment threshold of $5 or less, adjusted for inflation, 
under which issuers would not be required to trigger a grace period or 
terminate enrollment for enrollees who fail to pay the full amount of 
their portion of premium owed. We propose to limit application of this 
fixed-dollar payment threshold to premium payments after coverage is 
effectuated. Issuers would be required to apply the fixed-dollar 
threshold uniformly to all enrollees and without regard to their health 
status. Issuers would be allowed to apply either the fixed-dollar 
payment threshold or one of two percentage-based thresholds (one of 
which is currently permitted under Sec.  155.400(g), but which we 
propose to modify).
    We propose revisions to Sec.  155.505(b) to codify an option for 
application filers to file appeals on behalf of applicants and 
enrollees on the application filer's Exchange application, as this 
would streamline the appeals process and ensure operational consistency 
between the FFEs and the HHS appeals entity or State Exchange appeals 
entity.
    We propose to amend Sec.  155.1000 to state explicitly that an 
Exchange may deny certification to any plan that does not meet the 
general certification criteria at Sec.  155.1000(c). We also propose to 
amend Sec.  155.1090 with refinements to the standards for a request 
for the reconsideration of a denial of certification specific to the 
FFEs.
    We propose that in addition to collecting the information and data 
currently provided by Exchanges under Sec.  155.1200 to monitor 
performance and compliance, we would use the information and data that 
Exchanges submit to increase transparency into Exchange operations and 
to promote program improvements. We anticipate publicly releasing the 
Exchanges annual State-based Marketplace Annual Reporting Tools 
(SMARTs), programmatic and financial audits, Blueprint applications, 
and additional data points in the Open Enrollment (OE) Data Reports. We 
are seeking input on how to best display these data points and how to 
best develop a performance measurement tool to assess Exchange quality 
and consumer experience.
4. 45 CFR Part 156
    We solicit comments on reducing the risk of issuer insolvencies 
adversely impacting the integrity of the FFEs.
    We propose 2026 benefit year FFE and SBE-FP user fee rates of 2.5 
percent and 2.0 percent of total monthly premiums, respectively. 
However, if the enhanced PTC subsidies as currently enacted \15\ or at 
a higher level are extended through the 2026 benefit year by March 31, 
2025, we propose a 2026 benefit year FFE user fee rate range between 
1.8 and 2.2 percent of total monthly premiums and a 2026 benefit year 
SBE-FP user fee rate range between 1.4 and 1.8 of total monthly 
premiums, with each of these ranges to be set at a single rate in the 
final rule.
---------------------------------------------------------------------------

    \15\ ARP, Public Law 117-2 (2021). These enhanced subsidies were 
extended under the IRA, Public Law 117-169 (2022) and are scheduled 
to expire after the 2025 calendar year.
---------------------------------------------------------------------------

    We affirm that certain CSR loading practices that are permitted by 
State regulators are permissible under Federal law to the extent that 
they are reasonable and actuarially justified. We seek comment on 
whether we should codify this guidance at Sec.  156.80(d).
    We intend to revise the method for updating the AV Calculator, 
starting with the 2026 AV Calculator. Under this approach, for a plan 
year, we would only release a single, final version of the AV 
Calculator. We would also solicit public comments on the AV Calculator 
for a plan year generally but would only plan to incorporate this 
feedback into the development and release of the following plan year's 
AV Calculator.
    We propose to make minor updates to the standardized plan option 
designs for PY 2026 to ensure these plans continue to have AVs within 
the permissible de minimis range for each metal level and to maintain a 
high degree of continuity with the approaches to standardized plan 
options finalized in the 2023, 2024, and 2025 Payment Notices. In 
addition, we propose to amend Sec.  156.201 to require issuers that 
offer multiple standardized plan options within the same product 
network type, metal level, and service area to meaningfully 
differentiate these plans from one another in terms of included 
benefits, provider networks, and/or formularies.
    We propose to amend Sec.  156.202(b) and (d) to properly reflect 
the flexibility that issuers have been operationally permitted since 
these requirements were introduced to vary the inclusion of the 
distinct adult dental benefit coverage, pediatric dental benefit 
coverage, and/or adult vision benefit coverage categories under the 
non-standardized plan option limit in accordance with Sec.  
156.202(c)(1) through (3).
    We propose to conduct ECP certification reviews of plans for which 
issuers submit QHP certification applications in FFEs in States 
performing plan management functions, beginning in PY 2026.
    We propose to share aggregated, summary-level QIS information 
publicly on an annual basis beginning on January 1, 2026, with 
information QHP issuers submit during the PY 2025 QHP Application 
Period.
    We propose to amend Sec.  156.1220(a) to introduce a new 
materiality threshold for HHS-RADV appeals, such that HHS would rerun 
HHS-RADV results and adjust HHS-RADV adjustments to State transfers in 
response to a successful appeal when the impact of that appeal to the 
filer's HHS-RADV adjustments to State transfers is greater than or 
equal to $10,000.
5. 45 CFR Part 158
    We propose to amend Sec.  158.140(b)(4)(ii) to allow qualifying 
issuers to not adjust incurred claims by the net payments or receipts 
related to

[[Page 82317]]

the risk adjustment program for MLR reporting and rebate calculation 
purposes beginning with the 2026 MLR reporting year (MLR reports due in 
2027). We propose that for qualifying issuers, earned premium would 
account for net risk adjustment receipts by simply adding these net 
receipts to total premium, without subsequently subtracting them from 
adjusted earned premium, such that these net receipts would impact the 
MLR denominator rather than MLR numerator. We propose to amend Sec.  
158.103 to add a definition of ``qualifying issuer.''
    We also propose amendments to Sec.  158.240(c) to add an 
illustrative example of how qualifying issuers would calculate the 
amount of rebate owed to each enrollee to accurately reflect how such 
issuers would incorporate the net risk adjustment transfer amounts into 
the MLR and rebate calculations differently from other issuers, as well 
as a conforming amendment to clarify that the current illustrative 
example in paragraph (c)(2) would apply to issuers that are not 
qualifying issuers.

III. Provisions of the Proposed Regulations

A. 42 CFR Part 600 BHP Methodology Regarding the Value of the Premium 
Adjustment Factor (PAF)

1. Overview of the Payment Methodology and Calculation of the Payment 
Amount
    Section 1331(d)(3) of the ACA directs the Secretary to consider 
several factors when determining the Federal BHP payment amount, which, 
as specified in the statute, must equal 95 percent of the value of the 
PTC under section 36B of the Code and CSRs under section 1402 of the 
ACA that would have been paid on behalf of BHP enrollees had they 
enrolled in a QHP through an Exchange. Thus, the BHP payment 
methodology is designed to calculate the PTC and CSRs as consistently 
as possible and in general alignment with the methodology used by 
Exchanges to calculate advance payments of the PTC (APTC) and CSRs, and 
the methodology used to reconcile APTC with the amount of the PTC 
allowed for the tax year under section 36B of the Code. In accordance 
with section 1331(d)(3)(A)(iii) of the ACA, the final payment 
methodology must be certified by the Chief Actuary of CMS, in 
consultation with the Office of Tax Analysis (OTA) of the Department of 
the Treasury, as having met the requirements of section 
1331(d)(3)(A)(ii) of the ACA.
    Section 1331(d)(3)(A)(ii) of the ACA specifies that the payment 
determination shall take into account all relevant factors necessary to 
determine the value of the PTC and CSRs that would have been paid on 
behalf of eligible individuals, including but not limited to, the age 
and income of the enrollee, whether the enrollment is for self-only or 
family coverage, geographic differences in average spending for health 
care across rating areas, the health status of the enrollee for 
purposes of determining risk adjustment payments and reinsurance 
payments that would have been made if the enrollee had enrolled in a 
QHP through an Exchange, and whether any reconciliation of APTC and CSR 
would have occurred if the enrollee had been enrolled. Under all 
previous payment methodologies, the total Federal BHP payment amount 
has been calculated using multiple rate cells in each BHP State. Each 
rate cell represents a unique combination of age range (if applicable), 
geographic area, coverage category (for example, self-only or two-adult 
coverage through the BHP), household size, and income range as a 
percentage of FPL, and there is a distinct rate cell for individuals in 
each coverage category within a particular age range who reside in a 
specific geographic area and are in households of the same size and 
income range. The BHP payment rates developed are also consistent with 
the State's rules on age rating. Thus, in the case of a State that does 
not use age as a rating factor on an Exchange, the BHP payment rates 
would not vary by age.
    Under the methodology finalized in the July 2021 final BHP Payment 
Notice, the rate for each rate cell is calculated in 2 parts. The first 
part is equal to 95 percent of the estimated PTC that would have been 
allowed if a BHP enrollee in that rate cell had instead enrolled in a 
QHP in an Exchange. The second part is equal to 95 percent of the 
estimated CSR payment that would have been made if a BHP enrollee in 
that rate cell had instead enrolled in a QHP in an Exchange. These two 
parts are added together and the total rate for that rate cell would be 
equal to the sum of the PTC and CSR rates. As noted in the July 2021 
final BHP Payment Notice, we currently assign a value of zero to the 
CSR portion of the BHP payment rate calculation, because there is 
presently no available appropriation from which we can make the CSR 
portion of any BHP payment.
    The 2023 final BHP Payment Notice provides a detailed description 
of the structure of the BHP payments, including the equations, factors, 
and the values of the factors used to calculate the BHP payments. We 
are proposing one change to the methodology regarding the premium 
adjustment factor (PAF).
    The PAF is used to calculate the adjusted reference premium (ARP) 
that is used to calculate the BHP payment. The adjusted reference 
premium (ARP) is used to calculate the estimated PTC that would be 
allowed if BHP-eligible individuals enrolled in QHPs through an 
Exchange and is based on the premiums for the applicable second lowest 
cost silver plan during the applicable plan year. The PAF considers the 
premium increases in other States that took effect after we 
discontinued payments to issuers for CSRs provided to enrollees in QHPs 
offered through Exchanges. Despite the discontinuance of Federal 
payments for CSRs, QHP issuers are required to provide CSRs to eligible 
enrollees. As a result, many QHP issuers increased the silver-level 
plan premiums to account for those additional costs; these premium 
adjustments and how they were applied (for example, to only silver-
level plans or to all metal tier plans) varied across States. For the 
States operating BHPs in 2018, the increases in premiums were 
relatively minor, because the majority of enrollees eligible for CSRs 
(and all who were eligible for the largest CSRs) were enrolled in the 
BHP and not in QHPs on the Exchanges, and therefore issuers in BHP 
States did not significantly raise premiums to cover costs related to 
HHS not making CSR payments.
    In the Final Administrative Order and the 2019 through 2023 final 
BHP Payment Notices, we incorporated the PAF into the BHP payment 
methodologies to capture the impact of how other States responded to 
HHS ceasing to make CSR payments.\16\ We also reserved the right that 
in the case an appropriation for CSR payments is made for a future 
year, we would determine whether and how to modify the PAF in the 
payment methodology.
---------------------------------------------------------------------------

    \16\ <a href="https://www.medicaid.gov/sites/default/files/2019-11/final-admin-order-2018-revised-payment-methodology.pdf">https://www.medicaid.gov/sites/default/files/2019-11/final-admin-order-2018-revised-payment-methodology.pdf</a>.
---------------------------------------------------------------------------

    Under the Final Administrative Order, we calculated the PAF by 
using information sought from QHP issuers in each State and the 
District of Columbia and determined the premium adjustment that the 
responding QHP issuers made to each silver level plan in 2018 to 
account for the discontinuation of CSR payments to QHP issuers. Based 
on the data collected, we estimated the median adjustment for silver 
level QHPs nationwide (excluding those in the two BHP States). To the 
extent that QHP issuers made no adjustment (or the adjustment was 
zero), this was counted as zero in determining the median

[[Page 82318]]

adjustment made to all silver level QHPs nationwide. If the amount of 
the adjustment was unknown--or we determined that it should be excluded 
for methodological reasons (for example, the adjustment was negative, 
an outlier, or unreasonable)--then we did not count the adjustment 
towards determining the median adjustment.\17\ The median adjustment 
for silver level QHPs is referred to as the nationwide median 
adjustment.
---------------------------------------------------------------------------

    \17\ Some examples of outliers or unreasonable adjustments 
include (but are not limited to) values over 100 percent (implying 
the premiums doubled or more because of the adjustment), values more 
than double the otherwise highest adjustment, or non-numerical 
entries.
---------------------------------------------------------------------------

    For each of the two BHP States, we determined the median premium 
adjustment for all silver level QHPs in that State, which we refer to 
as the State median adjustment. The PAF for each BHP State equaled one 
plus the nationwide median adjustment divided by one plus the State 
median adjustment for the BHP State. In other words,

PAF = (1 + Nationwide Median Adjustment) / (1 + State Median 
Adjustment).

    To determine the PAF described above, we sought to collect QHP 
information from QHP issuers in each State and the District of Columbia 
to determine the premium adjustment those issuers made to each silver 
level plan offered through the Exchange in 2018 to account for the end 
of CSR payments. Specifically, we sought information showing the 
percentage change that QHP issuers made to the premium for each of 
their silver level plans to cover benefit expenditures associated with 
the CSRs, given the lack of CSR payments in 2018. This percentage 
change was a portion of the overall premium increase from 2017 to 2018.
    According to our 2018 records, there were 1,233 silver-level QHPs 
operating on Exchanges in 2018. Of these 1,233 QHPs, 318 QHPs (25.8 
percent) responded to our request for the percentage adjustment applied 
to silver-level QHP premiums in 2018 to account for the discontinuance 
of HHS making CSR payments. These 318 QHPs operated in 26 different 
States, with 10 of those States running State Exchanges (while we 
requested information only from QHP issuers in States serviced by an 
FFE, many of those issuers also had QHPs in State Exchanges and 
submitted information for those States as well). Thirteen of these 318 
QHPs were in New York (and none were in Minnesota). Excluding these 13 
QHPs from the analysis, the nationwide median adjustment was 20.0 
percent. Of the 13 QHPs in New York that responded, the State median 
adjustment was 1.0 percent. We believed that this was an appropriate 
adjustment for QHPs in Minnesota, as well, based on the observed 
changes in New York's QHP premiums in response to the discontinuance of 
CSR payments (and the operation of the BHP in that State) and our 
analysis of expected QHP premium adjustments for States with BHPs. We 
calculated the proposed PAF as (1 + 20%) / (1 + 1%) (or 1.20/1.01), 
which results in a value of 1.188.
    We set the value of the PAF to 1.188 for all program years for 2018 
through 2024, with limited exceptions.\18\ We believe that this value 
for the PAF continues to reasonably account for the increase in silver-
level premiums experienced in non-BHP States that took effect after the 
discontinuance of the CSR payments.
---------------------------------------------------------------------------

    \18\ 87 FR 77731, 77737.
---------------------------------------------------------------------------

    Starting in 2023, we made one limited exception in setting the 
value of the PAF as part of the 2023 final BHP Payment Notice.\19\ In 
the case of a State in the first year of implementing a BHP, if the 
State chooses to use prior year second lowest cost silver plan (SLCSP) 
premiums to determine the BHP payment (for example, the 2025 premiums 
for the 2026 program year), we set the value of the PAF to 1.00. In 
this case, we believe that adjustment to the QHP premiums to account 
for the discontinuation of CSR payments would be included fully in the 
prior year premiums, and no further adjustment would be necessary.
---------------------------------------------------------------------------

    \19\ Id. at 77732.
---------------------------------------------------------------------------

    We propose to make a change to the calculation of the PAF starting 
in program year 2026. There are cases in which a State may not have 
fully implemented BHP for a full program year. For example, a State may 
operate BHP for only a portion of the year (in other words, less than 
12 months); there may be other such cases in which a State would be 
deemed to have partially implemented BHP for a program year.
    For a State that initially only partially implemented BHP, it is 
likely that, in the year (or years) when the BHP is only partially 
implemented, the percentage adjustment to the premiums for the program 
year to account for the discontinuation of CSR payments may be 
significantly higher than the 1 percent adjustment we determined for 
BHP States in 2018. In these cases, it is probable that QHP issuers 
would include a larger premium adjustment (that is, greater than 1 
percent) because more individuals would be eligible for CSRs (and 
individuals eligible for relatively larger CSRs) would be enrolled in a 
QHP on the Exchange, for part or all of the initial implementation 
year. If premiums with a larger CSR adjustment are used as a basis for 
calculating the BHP payments and the current value of the PAF (1.188) 
is used, it is likely that this would ``double count'' a portion of the 
adjustment and lead to an effective CSR adjustment over 20 percent.
    For example, assume a State implements BHP for only 6 months in a 
program year. As a result, QHP issuers may include a 10 percent 
adjustment to the premiums to account for the discontinuation of the 
CSR for the portion of the year when CSR eligible individuals would 
have QHP coverage. The issuers would be liable for roughly half of the 
CSR amounts they would have had to provide if there was no BHP in 
place. Under the previous BHP payment methodology, if these premiums 
that already partially account for CSRs are used to calculate the BHP 
payment, we would increase the reference premium by 18.8 percent for 
the PAF, leading to an effective increase of 30.68 percent (1.188 
multiplied by 1.10 minus 1). This is significantly larger than the 20 
percent adjustment we determined as the basis for the PAF for States 
that have operated their BHP for more than two full program years.
    Under the Secretary's general authority to account for all relevant 
factors necessary to determine the value of the premium and cost-
sharing reductions that would have been provided to eligible 
individuals now enrolled in BHP coverage \20\ and to avoid such an 
overpayment, we propose the following changes to the PAF:
---------------------------------------------------------------------------

    \20\ Section 1331(d)(3)(A)(ii) of the PHS Act.
---------------------------------------------------------------------------

    (1) If a State has fully implemented BHP and is using SLSCP 
premiums for a year in which the BHP was fully implemented, then the 
value of the PAF would remain 1.188, as described above.
    (2) If a State is in the first year of implementing a BHP and the 
State chooses to use prior year SLCSP premiums to determine the BHP 
payment (for example, the 2025 premiums for the 2026 program year), we 
set the value of the PAF to 1.00. This is the same approach described 
in the 2023 final BHP Payment Notice.
    (3) If a State is using SLCSP premiums from a year in which BHP was 
not fully implemented, then the PAF is calculated as follows:

First, the State must determine the CSR adjustment that QHP issuers 
included in the SLSCP premiums for individual

[[Page 82319]]

market Exchange plans. The State should identify the SLSCP in each 
region, as defined for the Exchange. For each SLSCP, the State should 
determine the CSR adjustment that the QHP issuer included in the 
premium. This may be done by (1) reviewing any materials submitted by 
the QHP issuer describing the calculation of the premium; or (2) 
requesting that the QHP issuer provide the adjustment, or an estimate 
of the adjustment used in calculating the premium. Second, the State 
should report the CSR adjustments for the SLCSP for individual market 
Exchange plans for each region in the State to CMS. Third, CMS will 
take this percentage adjustment and calculate the PAF as 1.20 divided 
by 1 plus the adjustment. For example, if the percentage adjustment for 
the CSR is 5 percent, the PAF would be (1.20 / 1.05), or 1.143. The 
maximum value of the PAF would be 1.188, and the minimum value of the 
PAF would be 1.00.

    This approach would apply based on the premium year, not 
necessarily the program year. If the State has fully implemented BHP 
but is using the prior year premiums and BHP was not fully implemented 
in that year, this modified approach would still apply. For example, if 
a State partially implemented BHP in 2026 and fully implemented BHP in 
2027, when determining the BHP payments for 2027, we would then use 
1.188 for the value of the PAF if the State elected to use 2027 QHP 
premiums to determine the payment; if the State elected to use the 2026 
QHP premiums, then we would use the modified PAF calculation described 
in this section. CMS would make a determination of whether or not a BHP 
was fully implemented based on a review of the Blueprint and provide 
that determination to the State.
    We considered other approaches to the modified PAF. We considered 
whether or not CMS would collect data on the underlying CSR adjustment 
in the SLCSP premiums; however, we believe that such activities fall 
within States roles as BHP administrators and States are better able to 
work with QHP issuers to administer this data collection process. We 
also considered if States should survey all QHP issuers (not just those 
with the SLSCP premium). We believe that only using the CSR adjustment 
from individual market Exchange plans with the SLCSPs would be a more 
reasonable approach and would minimize the burden on States and QHP 
issuers by only requiring the State to work with one issuer in each 
region, as opposed to all issuers in each region. We also considered 
whether or not we should make further changes to the PAF, but we 
believe that this approach balances maintaining accurate BHP payments 
with stability and limited burden for BHP States. We request comments 
on this approach or alternative approaches to calculating the PAF.
2. Technical Clarification for Calculation of BHP Payment Rates in 
Cases of Multiple Second Lowest Cost Silver Plan Premiums in an Area
    The BHP payment rates are based on the second lowest cost silver 
plan premium among individual market QHPs operating on the Exchanges in 
each rating area (or county) in a State. This is the basis for the 
reference premium (or RP) in the BHP payment methodology.
    In general, we expect that each county would have a unique second 
lowest cost silver plan premium, which is used to calculate the payment 
rates for residents of that county for the BHP payment. However, in 
some cases, we have found that States may have more than one second 
lowest cost silver plan within a county. This may occur in cases where 
the State has allowed QHPs to operate in only a portion of the county 
instead of the entire county on the Exchange.
    In our previous BHP payment methodologies, we do not describe how 
such a case would be handled for calculating BHP payments. In our 
technical guidance to States, we have instructed States to report the 
premiums for the second lowest cost silver plan operating in the 
largest part of the county as measured by total population.
    Under the Secretary's general authority to account for all relevant 
factors necessary to determine the value of the premium and cost-
sharing reductions that would have been provided to eligible 
individuals now enrolled in BHP coverage,\21\ for the 2026 payment 
methodology and all subsequent years, we propose to clarify that in 
cases where there are more than one second lowest cost silver plans in 
a county, the BHP payment would be based on the premium of the second 
lowest cost silver plan applicable to the largest portion of the county 
as measured by total population. We welcome comments on this approach.

B. 45 CFR Part 153--Standards Related to Reinsurance, Risk Corridors, 
and Risk Adjustment

    In subparts A, B, D, G, and H of part 153, we established standards 
for the administration of the risk adjustment program. The risk 
adjustment program is a permanent program created by section 1343 of 
the ACA that transfers funds from issuers of lower-than-average risk, 
risk adjustment covered plans to issuers of higher-than-average risk, 
risk adjustment covered plans in the individual, small group markets, 
or merged markets, inside and outside the Exchanges. In accordance with 
Sec.  153.310(a), a State that is approved or conditionally approved by 
the Secretary to operate an Exchange may establish a risk adjustment 
program or have HHS do so on its behalf.\22\ HHS did not receive any 
requests from States to operate risk adjustment for the 2026 benefit 
year. Therefore, HHS will operate risk adjustment in every State and 
the District of Columbia for the 2026 benefit year.
---------------------------------------------------------------------------

    \22\ See also 42 U.S.C. 18041(c)(1).
---------------------------------------------------------------------------

1. Sequestration
    In accordance with the OMB Report to Congress on the Joint 
Committee Reductions for Fiscal Year 2025, the HHS-operated risk 
adjustment program is subject to the fiscal year 2025 
sequestration.\23\ The Federal government's 2025 fiscal year will begin 
on October 1, 2024. Therefore, the HHS-operated risk adjustment program 
will be sequestered at a rate of 5.7 percent for payments made from 
fiscal year 2025 resources (that is, funds collected during the 2025 
fiscal year).
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    HHS, in coordination with OMB, has determined that, under section 
256(k)(6) of the Balanced Budget and Emergency Deficit Control Act of 
1985 (BBEDCA),\24\ as amended, and the underlying authority for the 
HHS-operated risk adjustment program, the funds that are sequestered in 
fiscal year 2025 from the HHS-operated risk adjustment program will 
become available for payment to issuers in fiscal year 2026 without 
further Congressional action. If Congress does not enact deficit 
reduction provisions that replace the Joint Committee reductions, the 
program would be sequestered in future fiscal years, and any 
sequestered funding would become available in the fiscal year following 
that in which it was sequestered.

2. HHS Risk Adjustment (Sec.  153.320)
    The HHS risk adjustment models predict plan liability for an 
average enrollee based on that person's age, sex, and diagnoses (also 
referred to as hierarchical condition categories (HCCs)), producing a 
risk score. The State payment transfer formula \27\ that is part of the 
HHS Federally certified risk adjustment methodology utilizes separate 
models for adults, children, and infants to account for clinical and 
cost differences in each age group. In the adult and child models, the 
relative risk assigned to an individual's age, sex, and diagnoses are 
added together to produce an individual risk score. Additionally, to 
calculate enrollee risk scores in the adult models, we added enrollment 
duration factors beginning with the 2017 benefit year,\28\ and 
prescription drug categories (RXCs) beginning with the 2018 benefit 
year.\29\ Starting with the 2023 benefit year, we removed the severity 
illness factors in the adult models and added interacted HCC count 
factors (that is, additional factors that express the presence of a 
severity or transplant HCC in combination with a specified number of 
total payment HCCs or HCC groups on the enrollee's record) to the adult 
and child models \30\ applicable to certain severity and transplant 
HCCs.\31\
---------------------------------------------------------------------------

    \27\ The State payment transfer formula refers to part of the 
Federally certified risk adjustment methodology that applies in 
States where HHS is responsible for operating the program. The 
formula calculates payments and charges at the State market risk 
pool level (prior to the calculation of the high-cost risk pool 
payment and charge terms that apply beginning with the 2018 benefit 
year). See, for example, 81 FR 94080.
    \28\ For the 2017 through 2022 benefit years, there is a set of 
11 binary enrollment duration factors in the adult models that 
decrease monotonically from 1 to 11 months, reflecting the increased 
annualized costs associated with fewer months of enrollments. See, 
for example, 81 FR 94071 through 94074. These enrollment duration 
factors were replaced beginning with the 2023 benefit year with HCC-
contingent enrollment duration factors for up to 6 months in the 
adult models. See, for example, 87 FR 27228 through 27230.
    \29\ For the 2018 benefit year, there were 12 RXCs, but starting 
with the 2019 benefit year, the two severity-only RXCs were removed 
from the adult models. See, for example, 83 FR 16941.
    \30\ See table 4 for a list of factors in the adult models, and 
table 5 for a list of factors in the child models.
    \31\ See 87 FR 27224 through 27228. Also see table 6 below.
---------------------------------------------------------------------------

    Infant risk scores are determined by inclusion in one of 25 
mutually exclusive groups, based on the infant's maturity and the 
severity of diagnoses. If applicable, the risk score for adults, 
children, or infants is multiplied by a cost sharing reduction (CSR) 
adjustment factor. The enrollment-weighted average risk score of all 
enrollees in a particular risk adjustment covered plan (also referred 
to as the plan liability risk score (PLRS)) within a geographic rating 
area is one of the inputs into the State payment transfer formula, 
which determines the State transfer payment or charge that an issuer 
will receive or be required to pay for that plan for the applicable 
State market risk pool for a given benefit year. Thus, the HHS risk 
adjustment models predict average group costs to account for risk 
across plans, in keeping with the Actuarial Standards Board's Actuarial 
Standards of Practice for risk classification.
a. Data for HHS Risk Adjustment Model Recalibration for the 2026 
Benefit Year
    We are proposing to recalibrate the 2026 benefit year HHS risk 
adjustment models with the 2020, 2021, and 2022 enrollee-level EDGE 
data. Consistent with the approach outlined in the 2020 Payment Notice, 
we propose to recalibrate the HHS risk adjustment models for the 2026 
benefit year using only enrollee-level EDGE data, and to continue to 
use blended, or averaged, coefficients from the 3 years of separately 
solved models for the 2026 benefit year model recalibration.\32\ 
Additionally, as outlined in the 2022 Payment Notice (86 FR 24140, 
24152), we propose to use the 3 most recent consecutive years of 
enrollee-level EDGE data that are available at the time we estimate the 
draft recalibrated coefficients published in the proposed rule for the 
applicable benefit year.\33\ We believe this promotes stability, meets 
the goal of the HHS-operated risk adjustment program, and allows 
issuers more time to incorporate this information when pricing their 
plans for the upcoming benefit year.
---------------------------------------------------------------------------

    \32\ 84 FR 17463 through 17466.
    \33\ Although we do receive the next year of enrollee-level EDGE 
data prior to the proposed rule, that data must go through several 
quality and analysis checks before it is useable for HHS risk 
adjustment model recalibration.
---------------------------------------------------------------------------

    In the 2024 Payment Notice (88 FR 25740 through 25749), we 
finalized the use of 2018, 2019 and 2020 benefit year enrollee-level 
EDGE data for recalibration of the 2024 benefit year HHS risk 
adjustment models for all model coefficients. As explained in the 2024 
Payment Notice proposed rule (87 FR 78215 through 78216) and final rule 
(88 FR 25749 through 25753), we analyzed the 2020 benefit year data to 
identify possible impacts of the COVID-19 Public Health Emergency 
(PHE). Our analysis generally found that the 2020 enrollee-level EDGE 
data were anomalous primarily in the volume and frequencies of certain 
types of claims, but that the relative costs of specific services, at 
least those associated with payment HCCs in the HHS risk adjustment 
models, were largely unaffected. Because the HHS risk adjustment models 
predict relative costs of care for specific conditions on an enrollee-
level basis and tend not to rely on overall patterns of utilization, 
the minimal impacts to relative costs of care for payment HCCs likewise 
resulted in minimal impacts on the coefficients fitted by the 2020 
enrollee-level EDGE recalibration data.
    Then, in the 2025 Payment Notice (89 FR 26236 through 26238), we 
finalized the use of 2019, 2020 and 2021 benefit year enrollee-level 
EDGE data for recalibration of the 2025 benefit year HHS risk 
adjustment models for all model coefficients. As explained in the 2025 
Payment Notice proposed rule (88 FR 82527 through 82529) and final rule 
(89 FR 26236 through 26238), we recognized that the COVID-19 PHE was 
still in effect throughout the 2021 benefit year.\34\ Therefore, 
similar to our analysis of 2020 benefit year data to identify possible 
impacts of the COVID-19 PHE, we conducted additional analyses to 
determine whether any anomalies in the 2021 benefit year enrollee-level 
EDGE data were present beyond expected year-to-year variation and 
whether the use of 2 years of PHE-impacted data presented any 
additional concerns. Our analysis found that the coefficients for the 
2021 benefit year enrollee-level EDGE recalibration data were similar 
to the 2019 and 2020 benefit year's coefficients, with levels of 
variation consistent with typical changes in coefficients for new years 
of data. We did not identify any significant anomalies and incorporated 
the 2021 benefit year enrollee-level EDGE data in the 2025 risk 
adjustment model recalibration without exception.
---------------------------------------------------------------------------

    \34\ See, for example, ASPR. (2023, February 9). Renewal of 
Determination that a Public Health Emergency Exists. <a href="https://aspr.hhs.gov/legal/PHE/Pages/COVID19-9Feb2023.aspx">https://aspr.hhs.gov/legal/PHE/Pages/COVID19-9Feb2023.aspx</a>.
---------------------------------------------------------------------------

    Consistent with the approach for use of 2020 and 2021 benefit year 
enrollee-level EDGE data, we performed reviews of the 2022 benefit year 
enrollee-level EDGE data to identify potential anomalies prior to 
incorporating the 2022 benefit year enrollee-level EDGE data as part of 
the proposed recalibration of the HHS risk adjustment models for the 
2026 benefit year. Our review did not identify systematic anomalies in 
the 2022 enrollee-level EDGE data. Therefore, after considering our 
analysis of the 2020, 2021 and 2022

[[Page 82321]]

enrollee-level EDGE data, we propose to determine coefficients for the 
2026 benefit year HHS risk adjustment models based on a blend of 
separately solved coefficients from the 2020, 2021, and 2022 benefit 
years' enrollee-level EDGE data, with the costs of services identified 
from the data trended between the relevant year of data and the 2026 
benefit year.\35\ The draft coefficients listed reflect the use of 
trended 2020, 2021, and 2022 benefit year enrollee-level EDGE data, as 
well as other HHS risk adjustment model updates proposed in this 
proposed rule (including, for example, the proposed phasing out of the 
pricing adjustment for Hepatitis C drugs).\36\ However, we note that 
the draft coefficients could change between the proposed and final rule 
if we identify an error after publication of this proposed rule or if 
any proposed models are modified or not finalized in response to 
comments. In addition, consistent with Sec.  153.320(b)(1)(i), if we 
are unable to finalize the final coefficients in time for publication 
in the final rule, we would publish the final coefficients for the 2026 
benefit year in guidance soon after the publication of the final rule.
---------------------------------------------------------------------------

    \35\ As described in the 2016 Risk Adjustment White Paper 
(<a href="https://www.cms.gov/cciio/resources/forms-reports-and-other-resources/downloads/ra-march-31-white-paper-032416.pdf">https://www.cms.gov/cciio/resources/forms-reports-and-other-resources/downloads/ra-march-31-white-paper-032416.pdf</a>) and the 2017 
Payment Notice (81 FR 12218), we subdivide expenditures into 
traditional drugs, specialty drugs, medical services, and preventive 
services and determine trend factors separately for each category of 
expenditure. In determining these trend factors, we consult our 
actuarial experts, review relevant Unified Rate Review Template 
(URRT) submission data, analyze multiple years of enrollee-level 
EDGE data, and consult National Health Expenditure Accounts (NHEA) 
data as well as external reports and documents published by third 
parties. In this process, we aim to determine trends that reflect 
changes in cost of care rather than gross growth in expenditures. As 
such, we believe the trend factors we used for each expenditure 
category for the proposed 2026 benefit year models are appropriate 
for the most recent changes in cost of care that we have seen.
    \36\ Additionally, this rulemaking includes a proposal to 
incorporate pre-exposure prophylaxis (PrEP) into a separate model 
factor in the HHS risk adjustment adult and child models for the 
2026 benefit year. Although a separate proposed PrEP risk adjustment 
model factor is not included in tables 4 through 9, we do provide a 
comprehensive analysis of our considerations and structure for 
including a separate PrEP risk adjustment model factor, including 
the impact of the proposed addition of a PrEP factor on other model 
factors in that section of this rulemaking.
---------------------------------------------------------------------------

    We seek comment on the proposal to determine 2026 benefit year 
coefficients for the HHS risk adjustment models based on a blend of 
separately solved coefficients from the 2020, 2021, and 2022 enrollee-
level EDGE data.
b. Pricing Adjustment for the Hepatitis C Drugs
    Beginning with the 2026 benefit year, we propose to begin phasing 
out the market pricing adjustment \37\ to the plan liability associated 
with Hepatitis C drugs in the HHS risk adjustment models and start 
trending Hepatitis C drugs consistent with the other drugs \38\ in the 
HHS risk adjustment models. Since the 2020 benefit year HHS risk 
adjustment models, we have included a market pricing adjustment to the 
plan liability associated with Hepatitis C drugs to reflect future 
market pricing prior to solving for coefficients for the models.\39\ 
The purpose of this market pricing adjustment was to account for 
significant pricing changes between the data years used for 
recalibrating the models and the applicable benefit year of risk 
adjustment as a result of the introduction of new and generic Hepatitis 
C drugs.\40\ We have committed to annually reassessing the Hepatitis C 
pricing adjustment with additional years of enrollee-level EDGE data as 
the data becomes available.
---------------------------------------------------------------------------

    \37\ For discussion relating to the Hepatitis C Pricing 
Adjustment for previous benefit years, see, for example, 89 FR 26237 
through 26238.
    \38\ See 81 FR 12218 through 12219.
    \39\ The Hepatitis C drugs market pricing adjustment to plan 
liability is applied for all enrollees taking Hepatitis C drugs in 
the data used for recalibration.

---------------------------------------------------------------------------

    As part of the 2026 benefit year model recalibration analysis, we 
reassessed the cost trend for Hepatitis C drugs using available 
enrollee-level EDGE data (including 2022 benefit year data) to consider 
whether the pricing adjustment was still needed and, if it is still 
needed, whether it should be modified. We found that projected costs 
for Hepatitis C drugs have begun to rise alongside the expected cost of 
other specialty drugs after many years of decline and stagnation due to 
the introduction of new and generic Hepatitis C drugs. Therefore, we 
believe that it is appropriate to begin phasing out the market pricing 
adjustment for Hepatitis C drugs and start trending the cost of these 
drugs consistent with other similar drugs in the HHS risk adjustment 
models to ensure that we continue to use the most appropriate estimates 
of the average cost of Hepatitis C treatments for recalibration of the 
HHS risk adjustment models for the 2026 benefit year and beyond.
    To explain further, because the annual recalibration of our risk 
adjustment models use the most recent 3 years of enrollee-level EDGE 
data available at the time of the proposed rule (in the case of this 
proposed rule and the recalibration of the 2026 benefit year models: 
the 2020, 2021, and 2022 enrollee-level EDGE data) in our simulation of 
plan liability for the applicable benefit year, we apply trend factors 
to different categories of medical expenditures, including specialty 
drugs, for every calendar year between the applicable benefit year and 
each year of enrollee-level EDGE data.<SUP>41 42</SUP> For example, to 
project costs for 2026 benefit year risk adjustment, we trend the 2020 
enrollee-level EDGE data forward 6 years, the 2021 enrollee-level EDGE 
data forward 5 years, and the 2022 enrollee-level EDGE forward four 
years. We have previously developed the Hepatitis C market pricing 
adjustment by applying a separate annual trend factor to Hepatitis C 
drugs in lieu of applying the annual specialty drug trend we apply to 
all other specialty drugs. The intent of this adjustment is to track 
the projected decrease and stagnation of Hepatitis C drug prices due to 
the introduction of new and generic versions of Hepatitis C drugs as 
identified in various sources of available market data \43\ and through 
consultation with our actuarial experts. As illustrated by table 1, 
this proposal would continue to trend Hepatitis C drugs separately from 
specialty drugs to project decrease and stagnation of Hepatitis C 
treatment pricing changes

[[Page 82322]]

between 2020 and 2021 (for the 2020 EDGE data), between 2021 and 2022 
(for the 2020 and 2021 EDGE data), and between 2022 and 2023, between 
2023 and 2024, and between 2024 and 2025 for all three data years 
(2020, 2021, and 2022 EDGE data) used for recalibration of the 2026 
benefit year HHS risk adjustment models. Once we have trended Hepatitis 
C costs to reflect no growth from the 2020, 2021, and 2022 enrollee-
level EDGE data to the 2025 benefit year, under this proposal for 2026 
benefit year risk adjustment, we would complete the trending of these 3 
years of data from the 2025 benefit year to the 2026 benefit year by 
applying the specialty drug trend factor, rather than the Hepatitis C 
trend factor that reflects the unique market pricing adjustment for 
these drugs.
---------------------------------------------------------------------------

    \41\ See, supra, notes 38 and 39.
    \42\ Because EDGE data do not generally account for drug rebates 
per the EDGE Business Rules (available at <a href="https://regtap.cms.gov/reg_librarye.php?i=3765">https://regtap.cms.gov/reg_librarye.php?i=3765</a>), for the purposes of risk adjustment 
recalibration, we also incorporate assumptions about the incidence 
of drug rebates in our trending of prescription drug data.

---------------------------------------------------------------------------

    In other words, we propose to adopt a phased approach (See table 1) 
to transition the Hepatitis C drugs' trending as part of the annual 
recalibration of the HHS risk adjustment models beginning with the 2026 
benefit year to move away from the current unique market pricing 
adjustment for these drugs and align with the trending approach for 
specialty drugs as we expect that the current growth in Hepatitis C 
drug costs will continue to be similar to growth in specialty drug 
costs in future years. As described above, to begin this transition for 
the 2026 benefit year HHS risk adjustment models, we propose to apply 
the specialty drug trend to 1 year of trending Hepatitis C treatment 
costs (that is, the trend from 2025 to 2026) for all 3 years of 
enrollee-level EDGE data used in recalibration (that is, 2020, 2021, 
and 2022 enrollee-level EDGE data). These 3 years of enrollee-level 
EDGE data would otherwise be trended forward using the lower trend rate 
reflecting the market pricing adjustment for Hepatitis C treatments 
through the 2025 benefit year. As such, 2026 benefit year recalibration 
data for Hepatitis C would reflect 1 year of growth in the cost of 
treatment at the same rate as other specialty drugs. To continue the 
transition of phasing out the Hepatitis C drug pricing adjustment in 
future benefit years' annual model recalibration, under this proposal, 
we would annually increase the number of years for which we would use 
the specialty drug trend and decrease the number of years that would 
use the unique market pricing adjustment for Hepatitis C drugs. For 
example, as seen in table 1, for the recalibration of the 2027 benefit 
year HHS risk adjustment models, under this proposal, we would apply 
the specialty drug trend to 2 years of the trending used in the models 
to project growth in Hepatitis C drugs. Specifically, assuming that the 
2027 benefit year would use 2021, 2022, and 2023 enrollee-level EDGE 
data for the annual model recalibration, we would project Hepatitis C 
treatment pricing changes reflecting the unique market pricing 
adjustment between 2021 and 2022 (for the 2021 EDGE data), between 2022 
and 2023 (for the 2021 and 2022 EDGE data), and between 2023 and 2024 
and between 2024 and 2025 for all three data years (2021, 2022, and 
2023 EDGE data) used for the recalibration of the 2027 benefit year HHS 
risk adjustment models. Again, once we have trended Hepatitis C drug 
costs to reflect the unique market pricing adjustment from the 2021, 
2022, and 2023 enrollee-level EDGE data to the 2025 benefit year, under 
the proposed transitional approach, for recalibration of the 2027 
benefit year HHS risk adjustment models, we would complete the trending 
of these 3 years of data from the 2025 benefit year to the 2027 benefit 
year by applying the specialty drug trend factor between the 2025 and 
2026 benefit years and between the 2026 and 2027 benefit years. This 
approach would continue until such time as all enrollee-level EDGE data 
years used for the recalibration of the HHS risk adjustment models are 
from benefit year 2025 or later (See table 1), at which time the 
specialty drug cost trend would be fully applied to Hepatitis C drug 
costs consistent with other specialty drugs in the HHS risk adjustment 
models and we would stop applying the separate market pricing 
adjustment for Hepatitis C drugs as part of the annual model 
recalibration.

    We propose this transitional approach because we continue to 
believe a market pricing adjustment specific to Hepatitis C drugs in 
the simulation of plan liability as part of the annual recalibration of 
the HHS risk adjustment models for benefit years that involve the use 
of enrollee-level EDGE data prior to 2025 (for example, for 2026 
recalibration, the 2020 through 2022 enrollee-level EDGE data, and the 
2023 through 2025 intermediate years of trending) is necessary and 
appropriate to account for the lack of growth in Hepatitis C drug 
prices relative to other prescription drugs in the market between those 
data years and the 2025 benefit year.
    We seek comment on our proposal to phase out the market pricing 
adjustment and trend Hepatitis C drugs consistent with other specialty 
drugs starting with the annual recalibration of the 2026 benefit year 
HHS risk adjustment models.
c. Proposed Inclusion of Pre-Exposure Prophylaxis (PrEP) in the HHS 
Risk Adjustment Adult and Child Models as an Affiliated Cost Factor 
(ACF)
    We are proposing to incorporate human immunodeficiency virus (HIV) 
pre-exposure prophylaxis (PrEP) as a separate, new type of factor 
called an Affiliated Cost Factor (ACF) in the HHS risk adjustment adult 
and child models starting with the 2026 benefit year. This proposed 
change would reflect an evolution in our approach to defining the 
factors used in the HHS risk adjustment models to include a factor that 
is not indicative of an active condition and would change our current 
policy that models the costs of PrEP alongside all other preventive 
services.
    Starting with the 2021 benefit year HHS risk adjustment models, as 
finalized in the 2021 Payment Notice (85 FR 29185 through 29187), we 
incorporated PrEP in the simulation of plan liability in the HHS risk 
adjustment adult and child models as a preventive service with zero 
cost sharing after careful analysis of preventive drugs that are 
recommended at grade A or B by the United States Preventive Services 
Task Force (USPSTF), including analysis on when PrEP can used as a 
preventive service.\44\ Specifically, in June 2019, the USPSTF 
recommended the use of PrEP as a preventive service for persons who are 
at high risk of HIV acquisition.\45\ Because Section 2713 of the PHS 
Act, as added by Section 1001 of the ACA, requires that non-
grandfathered group health plans and health insurance issuers in the 
group and individual markets cover certain recommended preventive 
services without imposing cost sharing,\46\ we modified the

[[Page 82324]]

simulation of plan liability as part of the annual recalibration of the 
HHS risk adjustment adult and child models to account for the higher 
level of cost sharing associated with its status as a preventive 
service, similar to how we treat other preventive services.

---------------------------------------------------------------------------

    As a general principle, we currently incorporate preventive 
services into each of the HHS risk adjustment models to ensure that 100 
percent of the cost of those services are reflected in the simulation 
of plan liability. In the simulation of plan liability, services are 
only counted as preventive when they occur in the recommended 
circumstances (for example, age) to the extent we can identify such 
circumstances from enrollee-level EDGE data. As with other preventive 
services, the incorporation of PrEP into the simulation of plan 
liability as a preventive service tends to impact the age-sex 
coefficients for the population that is most likely to utilize the 
given preventive service. For PrEP, this population is typically males 
between the ages of 25 and 39, because this group composes the most 
frequent utilizers of PrEP in the enrollee-level EDGE data. In addition 
to PrEP drugs, like other preventive services,\47\ ancillary services 
related to PrEP care (for example, HIV screenings) qualify as 
preventive services and as such are also currently calibrated at 100 
percent plan liability in the recalibration of the HHS risk adjustment 
adult and child models.\48\
---------------------------------------------------------------------------

    \47\ For example, colonoscopies typically require a combination 
of several services between the drugs needed for the colonoscopy and 
the professional and institutional claims for the visit and 
procedure itself. Likewise, contraception coverage often requires a 
doctor's visit to obtain a prescription for the contraception.
    \48\ See 86 FR 24164.
---------------------------------------------------------------------------

    However, as a part of our commitment to consider ways to 
continually improve the HHS risk adjustment models, we continued to 
monitor and assess different ways to incorporate PrEP in the HHS risk 
adjustment models. In this regard, since the adoption of the current 
approach beginning with the 2021 benefit year HHS risk adjustment adult 
and child models, we have continued to assess the incorporation of PrEP 
into these models as we do other preventive services. We have also 
continued to receive recommendations from some interested parties that 
PrEP be incorporated into the HHS risk adjustment adult models 
differently than other preventive services in the calculation of plan 
liability due to the high cost of PrEP. We previously considered 
changing the treatment of PrEP to incorporate it in the HHS risk 
adjustment adult models as an RXC; however, we have always been 
concerned with this approach because RXCs are specifically incorporated 
as separate factors to impute a missing diagnosis or indicate severity 
of a diagnosis.\49\ As such, we did not incorporate PrEP into RXC 1 
(Anti-HIV Agents) because PrEP utilization does not indicate an HIV/
AIDS diagnosis or the severity of a diagnosis. We also considered 
incorporating the use of PrEP in the HHS risk adjustment models as a 
separate HCC, but we did not believe that approach would be appropriate 
because the principles for including an HCC into the models require 
that each HCC represents well-specified, clinically significant, 
chronic or systematic medical conditions.\50\ Because there is no 
active chronic medical condition involved, the use of PrEP for 
prevention of an HIV infection does not satisfy these criteria either.

---------------------------------------------------------------------------

    Additionally, when we initially incorporated PrEP as a preventive 
service in the simulation of plan liability in the HHS risk adjustment 
adult and child models, we expected that any risk of adverse selection 
regarding PrEP would decrease over time as we expected the costs of 
PrEP to decrease due to generics entering the market and gaining market 
share. We also expected minimal differences in issuers' populations of 
PrEP users because, under Section 2713 of the PHS Act and its 
implementing regulations at 45 CFR 147.130, all issuers of risk 
adjustment covered plans are required to cover PrEP and its ancillary 
services at zero cost sharing, consistent with the applicable USPSTF 
recommendation. Thus, we anticipated that the expected similarity 
across issuers' PrEP-associated cost sharing parameters would also 
mitigate the risk of adverse selection.
    More recently, we have continued to analyze PrEP and its usage in 
the individual, small group, and merged markets as additional benefit 
years of enrollee-level EDGE data became available. Because of PrEP's 
high costs relative to other preventive services, and in contrast to 
our initial assumptions about pricing decreases, our analysis of 2022 
benefit year enrollee-level data \51\ found that PrEP services can pose 
a unique risk of adverse selection to the extent that utilization of 
PrEP services differs between plans. More specifically, our analysis 
found that there are statistically significant, substantial differences 
in PrEP prevalence between issuers in rating areas where PrEP use is 
most common, indicating that the addition of a PrEP factor in the adult 
and child risk adjustment models would be appropriate and would have a 
meaningful impact on risk adjustment State transfers. Furthermore, our 
analysis also found that other considerations that helped inform the 
current approach (such as the expected decrease in costs as generics 
entered the market and gained market share) have not addressed the 
uniquely high costs of PrEP as a preventive service as we previously 
expected. For these reasons, we started to reconsider our approach and 
whether it should evolve to address other costs in the market (such as 
PrEP) that could impact the assessment of actuarial risk but which do 
not indicate the presence of a specific diagnosis.
---------------------------------------------------------------------------

    \51\ Prior to the 2021 Benefit Year, Plan ID and Rating Area 
were not included as part of the enrollee-level data extracted from 
issuers' EDGE data submissions. As finalized in the 2023 Payment 
Notice (87 FR 27241 through 27251), we now extract these fields as 
part of the enrollee-level EDGE dataset and are able to include them 
in our analyses. As such, this analysis and proposal reflects our 
earliest opportunity to reliably detect differences in prevalence 
within rating areas for any medical expenditures, including PrEP.
---------------------------------------------------------------------------

    We therefore tested incorporating a non-RXC and non-HCC model 
factor for PrEP in the HHS risk adjustment adult and child models to 
capture differences in costs for PrEP utilizers relative to the average 
enrollee. To signify that the potential new factor would not indicate 
the presence of a specific active medical condition, we refer to the 
potential new type of factor as an ``affiliated cost factor'' (ACF), 
thereby distinguishing this new type of potential factor from RXCs and 
HCCs.
    Generally speaking, similar to our approach when determining the 
HCCs and RXCs to be included in the HHS risk adjustment models,\52\ if 
adopted, we would rely on a set of principles to guide our decision 
making in developing any new ACF variable.
---------------------------------------------------------------------------

    \52\ See the 2014 Payment Notice Proposed Rule (77 FR 73128). 
See, also, the 2018 Payment Notice Proposed Rule (81 FR 61470).
---------------------------------------------------------------------------

    Principle 1--Like HCCs and RXCs, an ACF should be clinically 
meaningful, but in the case of ACFs, such variables

[[Page 82325]]

would be comprised of National Drug Codes (NDCs) or procedure codes 
that are not indicative of a diagnosis for a specific serious medical 
condition, in contrast to HCCs and RXCs. In other words, an ACF may 
refer to a preventive service (as in the case of a potential PrEP ACF), 
or to classes of treatments that may be applicable to a wide variety of 
disease states and are therefore too general to indicate a specific 
diagnosis. Nevertheless, codes included in an ACF should all relate to 
a reasonably well-specified pharmacologic, therapeutic or chemical 
characteristic that defines the category. The adherence to the 
principle of clinical meaningfulness maintains the face validity of the 
classification system and the models' interpretability.
    Principle 2--Like HCCs and RXCs, ACFs should meaningfully predict 
total medical and drug expenditures. Additionally, NDCs and procedure 
codes in an ACF should be reasonably homogeneous for their effect on 
current year costs, that is, the annual costs associated with NDCs or 
procedure codes triggering the ACF should fall within a reasonably 
limited range. Relative to the majority of NDCs or procedure codes in a 
given ACF, there should not be any extremely low or high cost NDCs or 
procedure codes included in the ACF.
    Principle 3--Like HCCs and RXCs, because ACFs would affect State 
transfers, these factors should have adequate sample sizes to permit 
accurate and stable estimates of expenditures. For example, it is 
difficult to reliably determine the expected cost of extremely rare 
categories.\53\
---------------------------------------------------------------------------

    \53\ For example, one extremely rare category that we have 
continued to analyze and consider for incorporation in the HHS risk 
adjustment models is gene therapy treatments. However, because these 
treatments are for rare conditions, and because there is substantial 
variation in costs from patient to patient for these treatments, 
through our ongoing monitoring and consideration of gene therapy 
treatments, we continue to find insufficient sample size and stable 
estimates of costs for the purposes of creating a new factor for 
these treatments in the HHS risk adjustment models.
---------------------------------------------------------------------------

    Principle 4--Like HCCs and RXCs, in creating an individual's 
clinical profile, hierarchies should be used to characterize the 
person's illness level within each disease process, where appropriate, 
while the effects of unrelated disease processes accumulate. Therefore, 
related HCCs, RXCs and ACFs should be treated hierarchically such that 
the most severe manifestation of a given specific potential disease 
process principally defines its impact on costs. As such, the presence 
of a relevant HCC or RXC in an enrollee's medical record, which would 
indicate the presence of a specific active medical condition, should 
preclude the application of a related ACF because ACFs do not indicate 
the presence of a specific active medical condition.
    Principle 5--As with HCCs and RXCs, issuers should not be penalized 
for a provider prescribing additional NDCs or coding additional medical 
conditions (monotonicity). This principle has two consequences for 
modeling of ACFs: (1) Like HCCs and RXCs, ACFs should not carry a 
negative payment weight; and (2) an HCC or RXC, or a relevant 
combination of an HCC, RXC, and interaction factor(s), reflecting the 
presence of a potential disease process to which the ACF is directly 
related should have at least as large a payment weight as the ACF.
    Principle 6--Like RXCs, we expect ACFs to primarily be composed of 
NDCs or service codes. As such, the classification for ACFs, like RXCs, 
should assign NDCs or service codes to only one ACF or RXC variable 
(mutually exclusive classification). Because each NDC can map to more 
than one RXC or ACF, the classification should map NDCs to the primary 
RXC or ACF variable based on considerations such as route of 
administration, intended application of the product, ingredient list 
identifier, label, dosage form, and strength of the drug.
    Principle 7--As with HCCs and RXCs, in evaluating the inclusion of 
ACFs, discretionary and noncredible drug or diagnosis categories should 
be excluded from payment models. ACFs that are particularly subject to 
prescribing variation or inappropriate prescribing by health plans or 
providers or to intentional or unintentional discretionary coding, or 
that are not clinically or empirically credible as cost predictors, 
should not be included.
    In developing an ACF variable reflecting PrEP, we are considering 
whether PrEP satisfies these principles and what approaches are 
necessary to appropriately balance all seven principles. A PrEP ACF 
would easily satisfy Principle 1 (clinically meaningful and specific), 
Principle 2 (meaningful and predictable costs \54\), Principle 3 
(sample size), and Principle 7 (low risk of inappropriate prescribing). 
PrEP is a well-defined regimen of medication that is only recommended 
to enrollees who meet certain risk factors,\55\ providing clinical 
meaningfulness and specificity. Regarding cost, with the exception of 
generics,\56\ the commonly available forms of PrEP are expensive and 
have similar costs,\57\ making the costs both meaningful and 
predictable. Furthermore, there are a sufficient number of enrollees in 
the enrollee-level EDGE data to produce a reliable estimate of PrEP 
costs for the HHS risk adjustment adult and child models. Finally, for 
a preventive service such as PrEP, we consider the uniquely high costs 
and low likelihood of over-prescribing to provide clinical and 
empirical credibility towards cost prediction, thereby satisfying the 
low risk of inappropriate prescribing required by Principle 7. 
Specifically, we consider there to be a low likelihood of 
overprescribing PrEP due to the high degree of ancillary services 
generally required to obtain and maintain access to a PrEP 
prescription. For example, as reflected by the U.S. Public Health 
Service clinical practice guidelines for PrEP,\58\ patients receiving 
oral PrEP generally must see a provider to be tested for HIV and other 
sexually transmitted infections every 3 months and have key liver and 
kidney function indicators tested every 6 months to 1 year.\59\ 
Additionally, we suspect \60\ that

[[Page 82326]]

there is a relatively low utilization rate of PrEP services among 
specific indicated populations, which would also indicate a low 
likelihood that PrEP is being overprescribed.
---------------------------------------------------------------------------

    \54\ As discussed later in this section, it may be appropriate 
to remove generic drugs to ensure homogeneity of costs within a PrEP 
ACF.

Injectable PrEP, which is administered by a provider in a clinical 
setting and is not available in NADAC data.
    \58\ See, supra, note 55.
    \59\ The costs of these ancillary services are currently 
captured in the age-sex coefficients, but the addition of a PrEP ACF 
to the HHS risk adjustment adult and child models would shift the 
risk contributed by ancillary services out of the age-sex factors 
into the PrEP ACF factor.
    \60\ In the enrollee-level EDGE data, we are unable to assess 
utilization rates from PrEP indicated populations because we are 
generally unable to identify the population of enrollees who would 
be eligible for PrEP but who are not utilizing the preventive 
service. Additionally, specific estimates of PrEP utilization among 
specific indicated populations are difficult to attain from other 
data sources at this point in time. The CDC has paused the 
publication of estimates of PrEP coverage in indicated populations 
and has advised against citing specific data points until June 2025 
due to data availability issues. (See Centers for Disease Control 
and Prevention. Monitoring selected national HIV prevention and care 
objectives by using HIV surveillance data--United States and 6 
territories and freely associated States, 2022. HIV Surveillance 
Supplemental Report 2024; 29(No. 2). <a href="https://www.cdc.gov/hiv-data/nhss/national-hiv-prevention-and-care-outcomes.html">https://www.cdc.gov/hiv-data/nhss/national-hiv-prevention-and-care-outcomes.html</a>).
---------------------------------------------------------------------------

    As mentioned above, we have found that PrEP overall satisfies 
Principle 2, having meaningful and predictable costs. In particular, 
our analyses found that the utilization patterns of PrEP medications 
have been fairly consistent year-over-year, with previously approved 
versions of PrEP medications maintaining substantial market share 
despite the availability of generic versions and new market entrants 
such as Apretude. If ACF medications and services that were commonly 
used in 1 year were largely supplanted by different medications or 
services in the following year, the cost predictions based on previous 
years of data may be inaccurate. Nevertheless, although we will 
continue to monitor the market for PrEP drugs, we generally do not 
anticipate substantial decrease in costs in the near future for 
enrollees taking brand name drugs due to the more convenient drugs and 
dose-forms (for example, long-acting injectable forms) coming to market 
\61\ and the retention of market share by existing branded drugs.
---------------------------------------------------------------------------

    \61\ Long-acting injectable PrEP may be beneficial in 
encouraging adherence to a PrEP medication regimen. (See, for 
example, <a href="https://getprepbroward.com/documents/Long-Acting-Injectable-PrEP.pdf">https://getprepbroward.com/documents/Long-Acting-Injectable-PrEP.pdf</a>). As such, we anticipate that treatment 
guidelines may recommend its use over oral PrEP in the future.
---------------------------------------------------------------------------

    Despite the overall anticipation that PrEP costs are consistent and 
will remain high over the next several years, we have found that there 
exists a large disparity in the costs of generic PrEP medication and 
the costs of brand name PrEP medication.\62\ Due to this disparity, if 
we include all PrEP medications in the definition of an ACF, the 
estimated coefficient will likely lead to overprediction for enrollees 
receiving generic medications and underprediction for enrollees 
receiving brand name medications. As such, it may be appropriate to 
exclude generic PrEP medication from the PrEP ACF, if one is adopted, 
which would exclude about 50 percent of enrollees with a PrEP 
prescription claim from the calculation of a PrEP ACF coefficient 
according to 2022 enrollee-level EDGE data. Such a low-cost exclusion 
from the ACF may improve predictions for enrollees receiving either 
generic or brand name PrEP medication and has precedent in our adoption 
of other factors in the HHS risk adjustment models. Specifically, we 
previously excluded generic drugs from RXC 9, Immune Suppressants and 
Immunomodulators, due to concern over patient access and health plan 
selection behavior.\63\ However, we believe that such an exclusion for 
a potential PrEP ACF could create incentives for prescribing brand over 
generic PrEP and therefore we solicit comments on balancing these 
considerations to help inform our consideration of the design of a 
potential PrEP ACF variable.

---------------------------------------------------------------------------

    As outlined by our discussion of Principles 1, 2, 3, and 7, our 
preliminary testing found minimal empirical concerns with a new PrEP 
ACF variable being added to the current HHS risk adjustment adult and 
child models, as the sample size for such a variable is reasonable for 
both the adult and child models, the clinical specifications are well 
defined, costs are generally predictable, and the resulting preliminary 
coefficient estimates for PrEP in the adult and child models are 
meaningful. However, in assessing Principles 4 (hierarchical factor 
definitions), 5 (monotonicity), and 6 (mutually exclusive 
classification), we found that the creation of a PrEP ACF variable 
would require further careful consideration.
    To satisfy Principle 4 (hierarchical factor definitions), the most 
severe manifestation of a given specific potential disease process must 
principally define its impact on costs. Therefore, related HCCs and 
RXCs (in the case of a PrEP ACF, the related HCC 1 for HIV/AIDS, and 
RXC 1 for anti-HIV agents) should be treated hierarchically. As such, 
in considering PrEP as a potential ACF, the presence of HCC 1 or RXC 1 
in an enrollee's medical record should preclude the application of the 
PrEP ACF, as the prevention of HIV infection clearly indicates a less 
severe manifestation of the specific potential disease process than 
treatment of an active HIV infection.
    However, the coefficient for HIV/AIDS (HCC 1) in the adult models 
\64\ has generally been lower than the coefficient we estimate would be 
calculated for a PrEP ACF. As such, without constraints applied to the 
HCC 1, RXC 1, and PrEP ACF coefficients, an adult enrollee who was on 
PrEP and later tested positive for HIV but did not start anti-
retroviral therapy for treatment within the same benefit year would 
have their risk score decrease between the initial application of the 
PrEP ACF, and its later replacement with HCC 1, violating monotonicity 
(Principle 5). Such enrollees make up a very small proportion of 
enrollees with a PrEP prescription claim (approximately 1.9 percent of 
enrollees with a PrEP prescription claim in the 2021 enrollee-level 
EDGE data). Additionally, this violation of monotonicity is not 
expected to take place in the HHS risk adjustment child models, as the 
lack of RXCs in the child models causes the coefficient for HCC 1 to be 
high enough that a PrEP ACF coefficient would not exceed the HCC for 
HIV/AIDS among child enrollees. Nevertheless, for consistency with the 
established principles for the HHS-operated risk adjustment program and 
the proposed principles to guide development of potential new ACF 
variables, we are considering solutions, described below, to the 
monotonicity concern for a PrEP ACF in the HHS risk adjustment adult 
models should we finalize the adoption of the proposed factor.
---------------------------------------------------------------------------

    \64\ Risk associated with HIV infection can be expressed in the 
value of HCC 1 or in the value of RXC 1. Because these factors are 
highly correlated, the value of each coefficient taken alone may 
fluctuate between benefit years. However, the additive value of 
these two factors in the HHS risk adjustment adult models is fairly 
consistent year-over-year.
---------------------------------------------------------------------------

    Additionally, a PrEP ACF could pose issues for mutually exclusive 
classification (Principle 6). Specifically, the compounds used in PrEP 
medication are also used to treat HIV. As such, NDCs for medications 
used for PrEP or the individual compounds alone are not enough to 
distinguish between an enrollee receiving PrEP and an enrollee in 
treatment for an active HIV infection. However, due to the necessity of 
the additional anti-retroviral compounds for HIV infection treatment, 
with special considerations and data filtering, we are generally able 
to distinguish enrollees that are receiving antiretroviral therapy for 
PrEP and those receiving antiretroviral treatment as treatment for HIV/
AIDS for the purposes of calculating plan liability with 100 percent 
cost sharing for PrEP and typical cost sharing treatment of HIV 
infection.<SUP>65 66</SUP> To address the

[[Page 82327]]

concerns for adherence to Principle 6, we will need to create a 
mutually exclusive NDC classification between RXC 1 and a PrEP ACF.
---------------------------------------------------------------------------

    \65\ See the 2021 Payment Notice (85 FR 29187).
    \66\ The medications used to treat HIV are also used as post-
exposure prophylaxis (PEP). Unlike PrEP, we are unable to 
distinguish between prescriptions for HIV treatment and 
prescriptions for PEP because the current guidelines for known 
exposures to HIV recommend the prescription of the same drugs as are 
used in treatment (See for example, <a href="https://stacks.cdc.gov/view/cdc/20711">https://stacks.cdc.gov/view/cdc/20711</a>) <a href="https://stacks.cdc.gov/view/cdc/20711">https://stacks.cdc.gov/view/cdc/20711</a>). However, we note that 
PEP requires a 28-day treatment regimen and, as such, has a much 
more limited impact on calculations of plan liability and risk than 
either treatment for an active HIV infection or PrEP. (See, for 
example, https://hivinfo.nih.gov/understanding-hiv/fact-sheets/post-
exposure-prophylaxis-
pep#:~:text=PEP%20stands%20for%20post%2Dexposure,used%20only%20in%20e
mergency%20situations.)
---------------------------------------------------------------------------

    To address the HHS risk adjustment adult modeling concerns we 
identified regarding Principles 4, 5 and 6, we are considering two 
alternative approaches. First, we could modify the current definition 
of RXC 1 (Anti-HIV agents) by treating PrEP NDCs as RXC 1 NDCs in 
limited circumstances based on individual enrollee characteristics. 
Alternatively, we could place the PrEP ACF in a hierarchy with RXC 1 
but define no hierarchical restrictions between PrEP and HCC 1 (HIV/
AIDS). We discuss these alternatives in detail below.
    Under the first approach, modifying the current definition of RXC 
1, we would add PrEP NDCs into RXC 1 (Anti-HIV agents) in limited 
circumstances to address situations where the adult enrollee has both a 
claim for PrEP and a claim for RXC 1 within the benefit year. 
Operationally, to capture these cases, the adult enrollees with a PrEP 
prescription claim would receive the RXC 1 flag instead of the ACF only 
in cases where the enrollee has both a PrEP prescription claim and an 
HIV diagnosis but does not have a typical RXC 1 prescription claim 
because the enrollee did not begin treatment for HIV, or because their 
treatment medication was provided at no cost to the issuer and 
therefore no claim was submitted to EDGE. As such, a PrEP NDC's 
classification as RXC 1 or the ACF would be contingent on the presence 
of HCC 1 (HIV/AIDS) on an adult enrollee's record. We estimate that 
less than 2 percent of adult enrollees with a PrEP prescription claim 
would meet these criteria, and that such enrollees would account for 
less than 1 percent of enrollees receiving RXC 1. As such, the sample 
size of the PrEP ACF would remain high and the impact on the RXC 1 
coefficient would be minimal. This approach to defining the 
hierarchical relationship between HCC 1, RXC 1, and the PrEP ACF would 
ensure that an adult enrollee with a PrEP prescription claim who later 
tested positive for HIV would have an increase in their risk score as a 
result of the additional diagnosis, satisfying Principles 4 
(hierarchical factor definitions) and 5 (monotonicity). Although this 
approach would not be strictly consistent with mutually exclusive 
classification of diagnosis codes and NDCs into only one variable 
(Principle 6), we find this to be acceptable in this limited 
circumstance because it would precisely dictate which model factor an 
adult enrollee would receive (which satisfies the intent of Principle 
6, mutually exclusive classification) and because PrEP medications can 
be part of an approved HIV treatment protocol when additional anti-
retroviral drugs are used. Thus, it is not unreasonable to assume that 
the few adult enrollees with PrEP prescription claims and an HIV 
diagnosis are also receiving the additional medications needed to meet 
treatment requirements.\67\
---------------------------------------------------------------------------

    \67\ It is possible such medications may not appear in the 
enrollee-level EDGE data if the issuer cost is completely covered by 
rebates or other assistance. In such cases, the cost of the 
medication would not influence plan liability calculations and would 
not impact the coefficient of a PrEP ACF.
---------------------------------------------------------------------------

    Under the alternative approach, we would address the violation of 
monotonicity in the HHS risk adjustment adult models by placing the 
PrEP ACF below RXC 1 in a hierarchy but defining no hierarchical 
relationship between the PrEP ACF and HCC 1 (HIV/AIDS), allowing adult 
enrollees without RXC 1 to receive the PrEP ACF along with HCC 1 in 
cases where the enrollee has both a PrEP prescription claim and an HCC 
1 diagnosis in their medical records for the benefit year. This 
approach would also ensure that an adult enrollee with a PrEP 
prescription claim who later tested positive for HIV would have an 
increase in their risk score as a result of the additional diagnosis, 
satisfying Principles 4 (hierarchical factor definitions) and 5 
(monotonicity). This alternative PrEP ACF-RXC 1 hierarchy approach 
would likewise satisfy the intent of Principle 6 (mutually exclusive 
classification) by using similar considerations and filtering steps to 
those we currently use in our simulation of plan liability for PrEP. We 
solicit comments on addressing these hierarchy, monotonicity, and 
mutual exclusivity concerns, and both alternative approaches outlined 
above that are designed to address those concerns.
    Table 2 below displays our testing of estimated values for the 
proposed PrEP ACF for the 2026 benefit year adult models using only 
2021 benefit year enrollee-level EDGE data, but otherwise following the 
specifications of the 2025 benefit year HHS risk adjustment adult 
models.\68\ We also included the values of the adult model factors that 
would likely be most impacted by the addition of a PrEP ACF to the 2026 
benefit year risk adjustment models in table 2. This helps demonstrate 
whether the PrEP ACF would adhere to Principles 4, 5, and 6 described 
above. As indicated in the table, the addition of the adult model 
coefficients for a PrEP ACF (in each metal level) to the adult models 
would only minorly impact other coefficients, with the most impacted 
model coefficients being the age-sex coefficients for males between the 
ages of 25 and 44, RXC 1 (Anti-HIV Agents), and a small handful of 
other HCCs and RXCs. All impacts beyond those displayed in this table 
reflect absolute impacts on HHS risk adjustment adult model coefficient 
values of less than 0.01. However, we note that these values have not 
been subjected to either our normal modeling constraints, nor any of 
the constraints discussed in relation to Principles 4, 5 and 6.
---------------------------------------------------------------------------

    \68\ For the specifications of the 2025 benefit year HHS risk 
adjustment adult and child models, including the Hepatitis C pricing 
adjustment and the list of factors included in the models, see the 
2025 Payment Notice (89 FR 26238 through 26256).

    Table 3 below displays estimated values for the proposed PrEP ACF 
for the 2026 benefit year HHS risk adjustment child models using only 
2021 benefit year enrollee-level EDGE data, but otherwise following the 
specifications of the 2025 benefit year HHS risk adjustment child 
models.\69\ Unlike the adult models, for the HHS risk adjustment child 
models, our testing found there are no impacts greater than 0.01 to the 
unconstrained coefficients for other child model factors. In this 
analysis for the child models, the approximate value of the
---------------------------------------------------------------------------

    \69\ Ibid.

---------------------------------------------------------------------------

[[Page 82331]]

PrEP ACF coefficient for children for the 2026 benefit year would fall 
below the HCC 1 (HIV/AIDS) coefficient for each metal level,\70\ 
affirming that the identified concerns over Principles 4, 5 and 6 among 
the HHS risk adjustment adult models do not apply to the HHS risk 
adjustment child models.
---------------------------------------------------------------------------

    \70\ As compared to the HCC 1 coefficients in table 5.
    [GRAPHIC] [TIFF OMITTED] TP10OC24.025
    
    Again, the above coefficient values in tables 2 and 3 have been 
calculated using the 2021 enrollee-level EDGE data only, with the 2025 
benefit year HHS risk adjustment model specifications, and without our 
normal modeling constraints nor any of the constraints discussed in 
relation to Principles 4, 5 and 6. Although we anticipate that these 
values will change slightly when the modeling constraints and the 2026 
benefit year risk adjustment model specifications are applied, if the 
proposed new PrEP ACF variable is added to the adult and child models, 
we believe these offer reliable estimates of the potential impact of 
the adoption of the proposed new PrEP ACF variable on other factors and 
approximate values for the proposed draft new PrEP ACF coefficients for 
the adult and child models. If this proposal is finalized, the final 
coefficients will be made available in the final rule or through 
subsequent notice-and-comment rulemaking or guidance, as appropriate.
    We solicit comments on our proposal to create a new ACF category of 
model factors for incorporation into the HHS risk adjustment models to 
account for unique medical expenses or services (such as PrEP) that do 
not meet the criteria to qualify as HCC or RXC factors, but impact the 
actuarial risk presented to issuers of risk adjustment covered plans. 
In addition, we solicit comments on our proposal to modify the 
treatment of PrEP in the HHS risk adjustment adult and child models 
beginning with the 2026 benefit year, as well as how to 
methodologically define a potential ACF category of model factors that 
accounts for PrEP (or other unique medical expenses or services) and 
what other considerations should be part of the analysis and modeling 
for this proposed new category of model factors (such as the 
availability of drug rebates \71\ or differences in medication 
adherence for PrEP). Furthermore, we solicit comments regarding the 
principles to guide inclusion of potential ACF factors and the 
discussed alternative approaches for defining a PrEP ACF's hierarchical 
relationship to HCC 1 and RXC1 to address the concerns related to 
hierarchical factor definitions (Principle 4), violations of 
monotonicity (Principle 5), and violations of mutually exclusive 
classification (Principle 6) in the HHS risk adjustment adult models. 
Additionally, we solicit comments on whether generic versions of PrEP 
medication should be excluded from the definition of the proposed ACF 
for PrEP. Lastly, we solicit comments concerning whether there are any 
similar medical expenses or services that we should consider for 
potential new ACFs alongside PrEP.
---------------------------------------------------------------------------

    \71\ For example, we believe there are likely substantial 
rebates for Descovy that are not captured in issuers' EDGE data 
submissions. See, for example, Dickson, S., Gabriel, N., and 
Hernandez, I. Estimated changes in price discounts for tenofovir-
inclusive HIV treatments following introduction of tenofovir

d. Proposed List of Factors To Be Employed in the HHS Risk Adjustment 
Models (Sec.  153.320)
    The proposed 2026 benefit year HHS risk adjustment model factors 
resulting from the equally weighted (averaged) blended factors from 
separately solved models using the 2020, 2021, and 2022 enrollee-level 
EDGE data are shown in tables 4 through 9.\72\ The HHS risk adjustment 
adult, child, and infant models have been truncated to account for the 
high-cost risk pool payment parameters by removing 60 percent of costs 
above the $1 million threshold.\73\ Table 4 contains proposed factors 
for each adult model, including the age-sex, HCCs, RXCs, RXC-HCC 
interactions, interacted HCC counts, and enrollment duration 
coefficients. Table 5 contains the proposed factors for each child 
model, including the age-sex, HCCs, and interacted HCC counts 
coefficients.\74\ Table 6 lists the proposed HCCs selected for the 
interacted HCC counts factors that would apply to the HHS risk 
adjustment adult and child models. Table 7 contains the proposed 
factors for each HHS risk adjustment infant model. Tables 8 and 9 
contain the HCCs included in the HHS risk adjustment infant models' 
maturity and severity categories, respectively.
---------------------------------------------------------------------------

    \72\ See, supra, note 36.
    \73\ As finalized in the 2020 Payment Notice (84 FR 17466 
through 17468), we will maintain the high-cost risk pool parameters 
for the 2020 benefit year and beyond, unless amended through notice-
and-comment rulemaking. We are not proposing changes to the high-
cost risk pool parameters for the 2026 benefit year. Therefore, we 
will maintain the $1 million threshold and 60 percent coinsurance 
rate for the 2026 benefit year.

e. Cost-Sharing Reduction Adjustments
    In the 2025 Payment Notice (89 FR 26252 through 26254), we 
finalized the updated CSR adjustment factors for American Indian/Alaska 
Native (AI/AN) zero-cost sharing and limited cost sharing CSR plan 
variant enrollees for the 2025 benefit year, and for all future benefit 
years, unless changed through notice-and-comment rulemaking. In the 
2025 Payment Notice (89 FR 26252 through 26254), we also finalized 
maintaining the existing CSR adjustment factors for silver plan variant 
enrollees (70 percent, 73 percent, 87 percent, and 94 percent AV plan 
variants) \75\ for the 2025 benefit year and beyond, unless changed 
through notice-and-comment rulemaking. Under this approach, we will no 
longer republish these factors in future annual HHS notice of benefit 
and payment parameter rules unless changes are being proposed.
---------------------------------------------------------------------------

    \75\ See 83 FR 16930 at 16953; 84 FR 17478 through 17479; 85 FR 
29190; 86 FR 24181; 87 FR 27235 through 27236; 88 FR 25772 through 
25774; and 89 FR 26252 through 26254.
---------------------------------------------------------------------------

    For the 2026 benefit year, we are not proposing to change the CSR 
adjustment factors as finalized in the 2025 Payment Notice and will 
maintain the existing CSR adjustment factors for the 2026 benefit year. 
Since we are not proposing any changes to the CSR adjustment factors 
for the 2026 benefit year, we are not republishing the CSR adjustment 
factors in this rule.\76\
---------------------------------------------------------------------------

    \76\ See CSR adjustment factors finalized in the 2025 Payment 
Notice at 89 FR 26252 through 26254.
---------------------------------------------------------------------------

f. Model Performance Statistics
    Each benefit year, to evaluate the HHS risk adjustment model 
performance, we examine each model's R-squared statistic and predictive 
ratios (PRs). The R-squared statistic, which calculates the percentage 
of individual variation explained by a model, measures the predictive 
accuracy of the model overall. The PR for each of the HHS risk 
adjustment models is the ratio of the weighted mean predicted plan 
liability for the model sample population to the weighted mean actual 
plan liability for the model sample population. The PR represents how 
well the model does on average at predicting plan liability for that 
subpopulation.
    A subpopulation that is predicted perfectly would have a PR of 1.0. 
For each of the current and proposed HHS risk adjustment models, the R-
squared statistic and the PRs are in the range of published estimates 
for concurrent HHS risk adjustment models.\77\ Because we propose to 
blend the coefficients from separately solved models based on the 2020, 
2021 and 2022 benefit years' enrollee-level EDGE data, we are 
publishing the R-squared statistic for each model separately to verify 
their statistical validity. The R-squared statistics for the proposed 
2026 benefit HHS risk adjustment models are shown in table 10.

3. Overview of the HHS Risk Adjustment Methodology: State Payment 
Transfer Formula
    In part 2 of the 2022 Payment Notice (86 FR 24183 through 24186), 
we finalized the proposal to continue to use the State payment transfer 
formula finalized in the 2021 Payment Notice for the 2022 benefit year 
and beyond, unless changed through notice-and-comment rulemaking. We 
explained that under this approach, we will no longer republish these 
formulas in future annual HHS notice of benefit and payment parameters 
rules unless changes are being proposed. We are not proposing any 
changes to the formula in this rule, and therefore, are not 
republishing the formulas in this rule. We therefore would continue to 
apply the formula as finalized in the 2021 Payment Notice (86 FR 24183 
through 24186) in the States where HHS operates the risk adjustment 
program in the 2026 benefit year.
    Additionally, as finalized in the 2020 Payment Notice (84 FR 17466 
through 17468), we will maintain the high-cost risk pool parameters for 
the 2020 benefit year and beyond, unless amended through notice-and-
comment rulemaking. We are not proposing any changes to the high-cost 
risk pool parameters for the 2025 benefit year; therefore, we would 
maintain the $1 million threshold and 60 percent coinsurance rate.\78\
---------------------------------------------------------------------------

    \78\ See 81 FR 94081. See also 84 FR 17467.
---------------------------------------------------------------------------

4. Solicitation of Comments--Time Value of Money in HHS-Operated Risk 
Adjustment Program
    HHS received feedback from some interested parties that, for the 
2023 benefit year, issuers of risk adjustment covered plans were 
impacted more by the time value of money, for the collection and 
remittance of State transfers that occurs 8 to 10 months after the 
conclusion of the benefit year,\79\ than in any previous benefit years 
of the HHS-operated risk adjustment program. Given that interest rates 
were the highest in 2023 than in any year since the passage of the ACA, 
the impact of the time value of money has changed and is higher than it 
has been historically. We therefore solicit comments on what impact the 
time value of money may have on issuers' assessment of actuarial risk 
and incentives for adverse selection.
---------------------------------------------------------------------------

    \79\ Charges are typically sent out in August in the year after 
the benefit year and the majority of payments typically made in 
September and October in the year after the benefit year; payments 
held for sequestration from charges collected prior to October 1st 
are released in November of the same year.
---------------------------------------------------------------------------

    Unlike Medicare Advantage's risk adjustment program, under which 
CMS makes risk-adjusted monthly payments to Medicare Advantage 
organizations during the coverage year (in advance of each month of 
coverage) using interim risk scores and then does a reconciliation to 
updated risk scores after the final deadline for submission of all risk 
adjustment data, the HHS-operated risk adjustment program for the 
individual, small group and merged markets uses a final data submission 
deadline 4 months after the end of the benefit year and calculates 
issuers' plan liability risk scores and the State transfer amounts 2 
months after that, resulting in State transfers being made 8 to 10 
months after the end of the benefit year.\80\ HHS typically announces 
State transfer amounts no later than June 30 of the year following the 
benefit year,\81\ begins to collect charges in August of the year 
following the benefit year, and begins to make payments to issuers in 
the fall of the year following the applicable benefit year. This 
process means that issuers whose enrollees have higher-than-average 
actuarial risk do not receive their State transfer payments until the 
fall of the year following the benefit year. Over this same time 
period, issuers whose enrollees have lower-than-average actuarial risk 
are able to benefit from the availability of capital from the 
collection of premiums for

[[Page 82348]]

investment that could accrue interest between the benefit year and when 
the collection of charges begins in August of the year following the 
benefit year, which we refer to as the ``time value of money.''
---------------------------------------------------------------------------

    \80\ The EDGE data submission deadline is April 30, or if such 
date is not a business day, the next applicable business day. See 45 
CFR 153.730. We note that the deadline for submission of 2023 
benefit year data was extended to provide issuers flexibility in 
managing the challenges associated with the Change HealthCare 
cybersecurity incident and its impact on risk adjustment covered 
plans. See CMS Announcement BY2023 EDGE Data Submission MLR 
Extension <a href="https://www.cms.gov/cciio/resources/regulations-and-guidance/downloads/by_2023_announcement_edge_data_submission_mlr_extension.pdf">https://www.cms.gov/cciio/resources/regulations-and-guidance/downloads/by_2023_announcement_edge_data_submission_mlr_extension.pdf</a>.
    \81\ Risk adjustment transfer amounts are typically announced no 
later than June 30, or if such date is not a business day, the next 
applicable business day. See 45 CFR 153.310(e). The date for 
announcement of transfer amounts for the 2023 benefit year was 
extended in recognition of the extension of the deadline for EDGE 
data submissions. See supra note 92. After transfer amounts for a 
benefit year are announced, collection of charges typically begins 
in August with payments beginning in September.
---------------------------------------------------------------------------

    To continue to ensure appropriate incentives exist in the 
individual, small group, and merged markets to cover both healthy and 
sick enrollees, we believe that this market dynamic, the time value of 
money, and its potential impact on actuarial risk and adverse selection 
should be discussed and considered. Consistent with section 1343 of the 
ACA, in States where HHS is responsible for operating the program,\82\ 
we calculate average actuarial risk to assess charges to issuers with 
risk adjustment covered plans with lower-than-average actuarial risk 
and to make payments to issuers with risk adjustment covered plans with 
higher-than-average actuarial risk. The ACA's permanent risk adjustment 
program for the individual, small group, and merged markets is intended 
to minimize the incentives for adverse selection, to help level the 
playing field between insurance companies, and to foster a stable 
market in which issuers provide coverage to individuals with higher 
health care costs and those who are sick have access to the coverage 
they need.
---------------------------------------------------------------------------

    \82\ Section 1321(c)(1) of the ACA directs the HHS Secretary to 
operate the risk adjustment program in any State that fails to elect 
to do so. Since the 2017 benefit year, HHS has operated the program 
in all 50 States and the District of Columbia.
---------------------------------------------------------------------------

    The impact of the time value of money has increased to levels 
significantly higher than those seen in the initial years after the 
passage of the ACA. For example, in January 2016, the annual short-term 
Applicable Federal Rate (AFR) interest rate was 0.75 percent, whereas 
in January 2023 the AFR interest rate had increased to 4.50 
percent.\83\ This increase in the time value of money could impact the 
individual, small group, and merged markets by changing the incentives 
faced by issuers enrolling lower-than-average risk populations rather 
than higher-than-average risk populations, as lower-risk populations 
not only have lower claims costs, but could result in potential accrued 
interest for their premium revenues, whereas issuers with higher-risk 
populations are expected to incur higher claims costs and would 
generally not be able to collect the potential accrued interest for 
their premium revenues. To further illustrate this issue, in a 
hypothetical State market risk pool with only two issuers, where the 
risk adjustment issuer with lower-risk enrollees owes a $1,000,000 
charge and the risk adjustment issuer with higher-risk enrollees 
receives a payment of $1,000,000, the charge issuer may have accrued an 
additional $45,000 in interest from the initial $1,000,000, and after 
paying the risk adjustment charge, would retain the $45,000, while the 
payment issuer is deprived of the same opportunity. Thus, we have 
received feedback from interested parties expressing concern about this 
scenario in the context of the HHS-operated risk adjustment program and 
concerns about how it could create incentives for adverse selection 
that could result in issuers that receive State transfer payments 
raising premiums to recoup lost opportunity costs from the time value 
of money.
---------------------------------------------------------------------------

    \83\ The IRS publishes all annual short-term AFRs at: <a href="https://www.irs.gov/applicable-federal-rates">https://www.irs.gov/applicable-federal-rates</a>. January 2016 AFR: <a href="https://www.irs.gov/pub/irs-drop/rr-16-01.pdf">https://www.irs.gov/pub/irs-drop/rr-16-01.pdf</a>; January 2023 AFR: <a href="https://www.irs.gov/pub/irs-drop/rr-23-01.pdf">https://www.irs.gov/pub/irs-drop/rr-23-01.pdf</a>.
---------------------------------------------------------------------------

    For these reasons, we solicit comments on the impact of the time 
value of money on the HHS-operated risk adjustment program, including 
the impact of the time value of money on issuers' assessment of 
actuarial risk and the incentives for adverse selection, and what 
possible solutions or mitigating steps we should consider to address 
the impact of the time value of money on the HHS-operated risk 
adjustment program in future rulemaking.
5. HHS Risk Adjustment User Fee for the 2026 Benefit Year (Sec.  
153.610(f))
    We propose an HHS risk adjustment user fee for the 2026 benefit 
year of $0.18 PMPM. Under Sec.  153.310, if a State is not approved to 
operate, or chooses to forgo operating, its own risk adjustment 
program, HHS will operate risk adjustment on its behalf. For the 2026 
benefit year, HHS will operate risk adjustment in every State and the 
District of Columbia. As described in the 2014 Payment Notice (78 FR 
15416 through 15417), HHS' operation of the risk adjustment program on 
behalf of States is funded through a risk adjustment user fee. Section 
153.610(f)(2) provides that, where HHS operates a risk adjustment 
program on behalf of a State, an issuer of a risk adjustment covered 
plan must remit a user fee to HHS equal to the product of its monthly 
billable member enrollment in the plan and the PMPM risk adjustment 
user fee specified in the annual HHS notice of benefit and payment 
parameters for the applicable benefit year.
    OMB Circular No. A-25 established Federal policy regarding user 
fees, and specifies that a user charge will be assessed against each 
identifiable recipient for special benefits derived from Federal 
activities beyond those received by the general public.\84\ The HHS-
operated risk adjustment program provides special benefits as defined 
in section 6(a)(1)(B) of OMB Circular No. A-25 to issuers of risk 
adjustment covered plans because it mitigates the financial instability 
associate with potential adverse risk selection.\85\ The HHS-operated 
risk adjustment program also contributes to consumer confidence in the 
health insurance industry by helping to stabilize premiums across the 
individual, merged, and small group markets.
---------------------------------------------------------------------------

    \84\ See Circular No. A-25 Revised. <a href="https://www.whitehouse.gov/wp-content/uploads/2017/11/Circular-025.pdf">https://www.whitehouse.gov/wp-content/uploads/2017/11/Circular-025.pdf</a>.
    \85\ Ibid.
---------------------------------------------------------------------------

    In the 2025 Payment Notice (89 FR 26218), we calculated the Federal 
administrative expenses of operating the HHS risk adjustment program 
for the 2025 benefit year to result in a risk adjustment user fee rate 
of $0.18 PMPM based on our estimated costs for HHS risk adjustment 
operations and estimated billable member months (BMM) for individuals 
enrolled in risk adjustment covered plans. For the 2026 benefit year, 
HHS proposes to use the same methodology to estimate our administrative 
expenses to operate the program. These costs cover development of the 
models and methodology, collections, payments, account management, data 
collection, data validation, program integrity and audit functions, 
operational and fraud analytics, interested parties training, 
operational support, and administrative and personnel costs dedicated 
to HHS-operated risk adjustment program activities. To calculate the 
risk adjustment user fee, we divided HHS' projected total costs for 
administering the program on behalf of States by the expected number of 
BMM in risk adjustment covered plans in States where the HHS-operated 
risk adjustment program will apply in the 2026 benefit year.\86\
---------------------------------------------------------------------------

    \86\ HHS did not receive any requests from States to operate 
risk adjustment for the 2026 benefit year. Therefore, HHS will 
operate risk adjustment in every State and the District of Columbia 
for the 2026 benefit year.
---------------------------------------------------------------------------

    We estimate that the total cost for HHS to operate the risk 
adjustment program on behalf of States for the 2026 benefit year will 
be approximately $65 million, roughly the same as the amount estimated 
for the 2025 benefit year.
    Similar to prior benefit years, we projected risk adjustment 
enrollment scenarios for the 2026 benefit year. For the 2021 through 
2025 benefit years, we projected increased enrollment in the

[[Page 82349]]

individual non-catastrophic market risk pool in most States, due to the 
enhanced PTC subsidies provided for in the American Rescue Plan Act of 
2021 (ARP) <SUP>87 88</SUP> and the extension of the enhanced PTC 
subsidies under Section 12001 of the Inflation Reduction Act of 2022 
(IRA) through the 2025 benefit year.\89\ For our 2026 user fee 
projected enrollment numbers, we considered the impact of the 
expiration of the enhanced PTC subsidies established in section 9661 of 
the ARP and extended in section 12001 of the IRA through the 2025 
benefit year on the enrollment in the individual, small group, and 
merged market risk pools for the 2026 benefit year and used those 
estimates to project the proposed 2026 benefit year HHS risk adjustment 
user fee rate. We also note that if any events such as Congress passing 
an extension of enhanced PTC subsidies, resulting in larger than 
expected growth in individual on Exchange enrollment or some other 
deviation from our expectations of current conditions that would 
significantly change our estimates around costs, enrollment 
projections, or the finalization of proposed risk adjustment policies 
between this proposed rule and the final rule, we may modify the HHS 
risk adjustment user fee rate proposed in this rule in the final rule. 
Because we project a similar budget to operate the HHS-operated risk 
adjustment program and do not estimate increased enrollment in the 2026 
benefit year beyond the 2024 benefit year level, we propose an HHS risk 
adjustment user fee of $0.18 PMPM for the 2026 benefit year.

6. Risk Adjustment Data Validation Requirements When HHS Operates Risk 
Adjustment (HHS-RADV) (Sec. Sec.  153.350 and 153.630)
    HHS conducts risk adjustment data validation under Sec. Sec.  
153.350 and 153.630 in any State where HHS is responsible for operating 
the risk adjustment program.\90\ The purpose of risk adjustment data 
validation is to ensure issuers are providing accurate high-quality 
information to HHS, which is crucial for the proper functioning of the 
HHS-operated risk adjustment program. HHS-RADV also ensures that risk 
adjustment transfers calculated under the State payment transfer 
formula reflect verifiable actuarial risk differences among issuers, 
rather than risk score calculations that are based on poor quality 
data, thereby helping to ensure that the HHS-operated risk adjustment 
program assesses charges to issuers with plans with lower-than-average 
actuarial risk while making payments to issuers with plans with higher-
than-average actuarial risk. HHS-RADV consists of an initial validation 
audit (IVA) and a second validation audit (SVA). Under Sec.  153.630, 
each issuer of a risk adjustment covered plan must engage an IVA 
entity. The issuer provides demographic, enrollment, and medical record 
documentation for a sample of enrollees selected by HHS to its IVA 
entity for data validation. Each issuer's IVA is followed by an SVA, 
which is conducted by an entity HHS retains to verify the accuracy of 
the findings of the IVA. Based on the findings from the IVA, or SVA (as 
applicable), HHS conducts error estimation to calculate an HHS-RADV 
error rate. The HHS-RADV error rate is then applied to adjust the plan 
liability risk scores of outlier issuers, as well as the risk 
adjustment transfers calculated under the State payment transfer 
formula for the applicable State market risk pools, for the benefit 
year being audited.
---------------------------------------------------------------------------

    \90\ Since the 2017 benefit year, HHS has operated the risk 
adjustment program in all 50 States and the District of Columbia.
---------------------------------------------------------------------------

a. Initial Validation Audit (IVA) Sampling Methodology--Enrollees 
Without HCCs, Finite Population Correction, and Neyman Allocation 
(Sec.  153.630(b))
    To better align the IVA sampling methodology with the HHS-RADV 
error estimation methodology that estimates hierarchical condition 
categories (HCC) error rates and to improve overall sampling precision, 
we are proposing to exclude enrollees without HCCs \91\ from IVA 
sampling, to remove the Finite Population Correction (FPC), and to 
replace the source of the Neyman allocation \92\ data used for IVA 
sampling purposes with 3 years of available HHS-RADV data beginning 
with benefit year 2025 HHS-RADV.\93\
---------------------------------------------------------------------------

    \91\ Adult enrollees with only RXCs do not have any HCCs, and 
therefore, as further explained in this preamble, would be excluded 
from IVA sampling under this proposal.
    \92\ Neyman allocation is a method to allocate samples to strata 
based on the strata variances. A Neyman allocation scheme provides 
the most precision for estimating a population mean given a fixed 
total sample size. See <a href="http://methods.sagepub.com/reference/encyclopedia-of-survey-research-methods/n324.xml">http://methods.sagepub.com/reference/encyclopedia-of-survey-research-methods/n324.xml</a>.
    \93\ Activities related to the 2025 benefit year of HHS-RADV 
will generally begin in Spring 2026, when issuers can start 
selecting their IVA entity, and IVA entities can start electing to 
participate in HHS-RADV for the 2025 benefit year. Changes to the 
IVA sampling methodology need to be finalized before HHS-RADV 
activities begin; therefore, we are proposing these IVA sampling 
changes begin with 2025 benefit year HHS-RADV due to the timing of 
this rulemaking. For an example of the typical annual HHS-RADV 
timeline, see the 2023 Benefit Year HHS-RADV Activities Timeline.

---------------------------------------------------------------------------

1. IVA Sampling Background
    HHS-RADV IVA sampling policy was originally described in the 2014 
Payment Notice (78 FR 15436) where we stated that HHS would choose a 
sample size of enrollees for HHS-RADV such that the estimated risk 
score errors would be statistically sound, and the enrollee-level risk 
score distributions would reflect enrollee characteristics for each 
issuer. To implement this approach, in the 2015 Payment Notice (79 FR 
13756 through 13758), we finalized two key aspects of the IVA sampling 
methodology. First, HHS set the IVA sample size as 200 enrollees per 
issuer, as sample size precision analyses performed at the time with 
data available from Medicare Advantage RADV (MA-RADV) program, which 
utilizes a similar HCC-based methodology as the HHS-RADV methodology, 
indicated that a sample size of 200 enrollees would achieve the 
targeted precision for an average sized issuer and that there would be 
no meaningful improvement in the estimated level of precision with 
larger sample sizes. In particular, to establish this 200-enrollee 
sample, we set a 10 percent sampling precision target at a two-sided 95 
percent confidence level. That is, we aimed to obtain a sample size 
such that 1.96 multiplied by the standard error, divided by the 
estimated adjusted risk score, equals 10 percent or 
less.<SUP>94 95</SUP> To translate this policy to small issuers, we 
established an FPC factor to calculate a modified IVA sample size 
smaller than 200 enrollees.\96\ If an issuer

[[Page 82350]]

has between 51 and 3,999 enrollees, the issuer's IVA sample size is 
calculated by multiplying the FPC factor, which is a factor less than 
one, by the standard sample size of 200.\97\ If an issuer has 50 or 
fewer enrollees, its sample size is equal to its enrollment. Second, 
the policies finalized in the 2015 Payment Notice established that the 
IVA sampling methodology would use a simple age and risk score 
stratification that categorizes the relevant population into 10 strata, 
representing different demographic and risk score bands, and use a 
Neyman allocation sampling methodology to select an issuer's IVA sample 
for a given benefit year.<SUP>98 99 100</SUP> This stratified design 
was intended to ensure adequate sample selection of the higher risk 
portion of the enrollee population and the Neyman allocation increases 
the likelihood that the sample achieves targeted levels of precision 
because strata with greater variance will be sampled more heavily.\101\

    \95\ We established this sampling precision target in the 
initial year of HHS-RADV based on a survey of guidance from the OMB, 
Internal Revenue Service (IRS), and the HHS-developed Payment Error 
Rate Measurement (PERM) program.
    \96\ An FPC is traditionally used when sampling without 
replacement from a finite population and the sample size, n, is 
significant in comparison with the population size, N, so that no 
more than 5 percent of the population is sampled. The FPC formula 
can be found in Section 2.6: Cochran, William G., Sampling 
Techniques, third edition, John Wiley & Sons, 1977.

    \98\ See 79 FR 13756 through 13758.
    \99\ See supra note 92.
    \100\ In the initial years of HHS-RADV, we constrained the 
``10th stratum'' of the IVA sample--that is, enrollees without HCCs 
selected for the IVA sample--to be one-third of the sampled IVA 
enrollees. In the 2020 Payment Notice, we finalized the extension of 
the Neyman allocation sampling methodology to the 10th stratum to 
improve sample precision and permit for a larger portion of the 
sample to be allocated to the HCC strata. See 84 FR 17494 through 
17495.
    \101\ See 78 FR 72332.
---------------------------------------------------------------------------

    Under the current risk score stratification in IVA sampling, to 
align with the HHS-operated risk adjustment program's three separate 
models for adult, child, and infants, we group each issuer's enrollee 
population into 10 strata based on age group, risk level, and presence 
of HCCs and prescription drug factors (RXCs) \102\ as follows:
---------------------------------------------------------------------------

    \102\ In the 2020 Payment Notice, we finalized piloting the 
incorporation of RXCs into the HHS-RADV process in the 2018 benefit 
year, which was the first year that RXCs were incorporated into the 
risk adjustment models. We also finalized incorporating RXC 
validation into HHS-RADV as a method of discovering materially 
incorrect EDGE server data submissions in a manner similar to how we 
address demographic and enrollment errors discovered during HHS-RADV 
beginning with the 2019 benefit year. See 84 FR 17501. We later 
extended the pilot years of incorporating RXCs into HHS-RADV to the 
2019 and 2020 benefit years of HHS-RADV to increase consistency 
between the operations of these benefit years' HHS-RADV and 
facilitate the combination of the HHS-RADV adjustments for these 
benefit years as we transitioned to a concurrent application of HHS-
RADV results. See 85 FR 77002 through 77005.
---------------------------------------------------------------------------

    <bullet> Strata 1-3 includes low, medium, and high risk adults with 
the presence of at least one HCC or RXC.
    <bullet> Strata 4-6 includes low, medium, and high risk children 
with the presence of at least one HCC.
    <bullet> Strata 7-9 includes low, medium, and high risk infants 
with the presence of at least one HCC.
    <bullet> Stratum 10 includes the No-HCC and No-RXC population, 
which is not further stratified by age group, because we assume this 
stratum has a uniformly low risk level.
    The current IVA sampling methodology relies on MA-RADV proxy data 
to conduct the Neyman allocation, which optimizes stratum sample size 
by selecting the number of enrollees to be sampled from each of the 10 
strata, listed above, that is proportional to each stratum's 
contribution to the total standard deviation of the population.\103\ 
The Neyman allocation formula for the overall sample size for each 
stratum of the issuer's IVA sample (ni,h) is:
---------------------------------------------------------------------------

    \103\ In the Neyman allocation, risk score error is measured as 
the actual difference between enrollee's audit risk scores and EDGE 
risk scores and does not reflect the error rate derived in HHS-RADV 
error estimation.
[GRAPHIC] [TIFF OMITTED] TP10OC24.043

---------------------------------------------------------------------------
Where:

<bullet> Ni,h is the population size of the h<SUP>th</SUP> stratum 
of issuer i.
<bullet> ni is the IVA sample size of issuer i.
<bullet> H is the total number of strata.
<bullet> Si,h represents the standard deviation of risk score error 
amount for the h<SUP>th</SUP> stratum.

    As described in the 2015 Payment Notice (79 FR 13756 through 
13758), we use MA-RADV data to calculate the standard deviation of risk 
score error (Si,h) across all 10 strata. At the time, we chose to use 
MA-RADV data when establishing the Neyman allocation because HHS-RADV 
data was not available and the MA-RADV program utilizes a similar HCC-
based methodology. Because MA-RADV data does not have child or infant 
age groups, we can only calculate a single standard deviation of risk 
score error for each risk-score subgrouping (low, medium and high). 
Therefore, to use the MA-RADV data, we assume that the standard 
deviation of risk score error within a risk-score subgrouping is the 
same for each of the three age groups (adult, child, and infant) in the 
HHS-RADV population. Given our assumptions on the strata net risk score 
errors and variances from the MA-RADV data, we found that 200 enrollees 
would be an appropriate IVA sample size to achieve 10 percent sampling 
precision for net risk score error for an average-sized issuer. We also 
explained that we intended to test and evaluate HHS-RADV data for use 
for this purpose in future years when it became available.\104\
---------------------------------------------------------------------------

    \104\ See 79 FR 13757.
---------------------------------------------------------------------------

    HHS-RADV error estimation has been modified over time without 
making corresponding changes to the IVA sampling methodology. For 
example, in the 2019 Payment Notice (83 FR 16961 through 16965), we 
finalized an HCC-failure rate error estimation methodology that adjusts 
an issuer's enrollees' risk scores when the issuer's failure rate for a 
group of HCCs is statistically different from a national 
benchmark.\105\ This methodology specifically calculates IVA-sampled 
enrollees' risk scores using their HCCs on EDGE and adjusts the HCC-
portion of enrollees' risk scores based on audit results for issuers 
identified as outliers.\106\ In the 2020 Payment Notice, we finalized a 
policy to incorporate RXCs beginning with 2018 benefit year HHS-RADV, 
and the 2021 Payment Notice finalized treating RXC validations in HHS-
RADV as late-filed discrepancies, similar to demographic and enrollment 
errors.<SUP>107 108 109</SUP> In

[[Page 82351]]

addition, in the 2024 Payment Notice, to promote consistency between 
the EDGE Server Business Rules and the HHS-RADV Protocols, HHS 
discontinued the Lifelong Permanent Conditions List and the policy 
permitting the submission of non-EDGE claims in HHS-RADV beginning with 
the 2022 benefit year of HHS-RADV.\110\
