I. Executive Summary

    We are finalizing changes to the provisions and parameters 
implemented through prior rulemaking to implement the ACA.\1\ These 
requirements are published under the authority granted to the Secretary 
by the ACA and the Public Health Service (PHS) Act.\2\ In this final 
rule, we are finalizing changes related to some of the ACA provisions 
and parameters we previously

[[Page 4425]]

implemented and are finalizing new provisions. Our goal with these 
requirements is to provide quality, affordable coverage to consumers 
while minimizing administrative burden and ensuring program integrity. 
The changes in this final rule are intended to help advance health 
equity, mitigate health disparities, and alleviate discrimination.
---------------------------------------------------------------------------

    \1\ The Patient Protection and Affordable Care Act (Pub. L. 111-
148, 124 Stat. 119) was enacted on March 23, 2010. The Healthcare 
and Education Reconciliation Act of 2010 (Pub. L. 111-152, 124 Stat. 
1049), 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.
    Below, we summarize sections of the PHS Act and ACA that are 
relevant to this final rule.
    Section 2718 of the PHS Act, as added by the ACA, generally 
requires health insurance issuers offering group or individual health 
insurance coverage 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 essential health benefits (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 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 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,

[[Page 4426]]

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 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 
program), section 1342 of the ACA (risk corridors program), and 
section 1343 of the ACA (risk adjustment program).

stabilization programs, set forth certain oversight provisions, and 
establish payment parameters in those programs.
    <bullet> In the May 27, 2014 Federal Register (79 FR 30240), we 
announced the fiscal year 2015 sequestration rate for the HHS-operated 
risk adjustment program.
    <bullet> In the February 27, 2015 Federal Register (80 FR 10749) 
(2016 Payment Notice), we finalized the benefit and payment parameters

premium stabilization programs, set forth certain oversight provisions, 
and establish the payment parameters in those programs.
    <bullet> In the March 8, 2016 Federal Register (81 FR 12203) (2017 
Payment

[[Page 4427]]

Notice), we finalized the benefit and payment parameters for the 2017 
benefit year to expand the provisions related to the premium 
stabilization programs, set forth certain oversight provisions, and 
establish the payment parameters in those programs.
    <bullet> In the December 22, 2016 Federal Register (81 FR 94058) 
(2018 Payment Notice), we finalized the benefit and payment parameters 
for the 2018 benefit year, added the high-cost risk pool parameters to 
the HHS risk adjustment methodology, incorporated prescription drug 
factors in the adult models, established enrollment duration factors 
for the adult models, and finalized policies related to the collection 
and use of enrollee-level External Data Gathering Environment (EDGE) 
data.
    <bullet> In the April 17, 2018 Federal Register (83 FR 16930) (2019 
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\

    \5\ CMS. (2018). Updated 2019 Benefit Year Final HHS Risk 
Adjustment Model Coefficients. <a href="https://www.cms.gov/CCIIO/Resources/Regulations-and-Guidance/Downloads/2019-Updtd-Final-HHS-RA-Model-Coefficients.pdf">https://www.cms.gov/CCIIO/Resources/Regulations-and-Guidance/Downloads/2019-Updtd-Final-HHS-RA-Model-Coefficients.pdf</a>.
---------------------------------------------------------------------------

    <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 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 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\

[[Page 4428]]

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 requested 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 based on price, quality, and other factors. This included 
implementation of components of the Exchanges and standards for 
eligibility for Exchanges, as well as network adequacy and 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

[[Page 4429]]

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; reduce 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 Plan Year (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 2 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 PY, 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 1 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 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 the 2025 Payment Notice does not 
address the application of this policy to large group market health 
plans and self-insured group health plans, and 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 requested comment on section 2718 of the PHS Act in the April 
14, 2010 Federal Register (75 FR 19297)

[[Page 4430]]

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), 
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 77722), 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 the final rule are codified in 42 CFR 
part 600 and 45 CFR parts 153, 155, 156, and 158.
1. 42 CFR Part 600
    We are finalizing changes to the methodology regarding the premium 
adjustment factor (PAF), which is used to calculate the adjusted 
reference

[[Page 4431]]

premium (ARP) for BHP payment. We are finalizing 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 will be set to 1.00. 
We are finalizing 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 finalizing 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 are unable to complete the calculations for the final 
coefficients for the 2026 benefit year in time to publish them in this 
final rule. Therefore, consistent with Sec.  153.320(b)(1)(i), we are 
finalizing the datasets to be used to calculate the final coefficients 
in this rule and will publish the final coefficients for the 2026 
benefit year in guidance after the publication of this final rule. 
Starting with the 2026 benefit year, we are finalizing the proposal 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 are also finalizing 
the incorporation of 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 are finalizing a risk adjustment user fee for the 2026 benefit year 
of $0.20 per member per month (PMPM).
    Beginning with the 2025 benefit year of HHS-RADV, we are finalizing 
the proposals to exclude enrollees without HCCs, which includes adult 
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 consecutive 
years of HHS-RADV data. In addition, beginning with the 2024 benefit 
year of HHS-RADV, we are finalizing the proposals to modify the SVA 
pairwise means test, which tests for statistically significant 
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 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 are finalizing revisions at 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 are finalizing updates to the model consent form that agents, 
brokers, and web-brokers can use to obtain and document consumer 
consent.\14\ The updates 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 updates also add scripts that agents, 
brokers, and web-brokers may utilize to meet the consumer consent and 
eligibility application review requirements finalized in the 2024 
Payment Notice via an audio recording.

    We are finalizing, in connection with the failure to file and 
reconcile process at Sec.  155.305(f)(4), that Exchanges are required 
to send notices to tax filers or their enrollees for the second year in 
which they have been determined to have failed to reconcile APTC 
explaining that they risk being determined ineligible for APTC. A 
notice to the tax filer may specifically explain that if they fail to 
file and reconcile for a second consecutive year, they risk being 
determined ineligible for APTC. Alternatively, an Exchange may send a 
more general notice to the enrollee or their tax filer explaining that 
they are at risk of losing APTC, without the additional detail that the 
tax filer has failed to file and reconcile APTC.
    We are finalizing the addition of 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) through (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.\15\

    We are finalizing a provision at Sec.  155.400(g) to allow issuers 
to adopt a fixed-dollar payment threshold of $10 or less, to be 
adjusted for inflation by annual agency guidance, 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, provided they do not owe more than the threshold amount. 
We are also finalizing a provision allowing issuers to adopt a gross 
percentage-based premium threshold of 98 percent or higher, which 
similarly would not require issuers to trigger a grace period

[[Page 4432]]

or terminate enrollment for enrollees who fail to pay the full amount 
of their portion of premium owed, provided they do not owe more than 
the threshold amount. In addition, we are finalizing a provision that 
permits issuers to set the premium payment threshold based on net 
premium owed by the enrollee at 95 percent or higher of the net 
premium, rather than providing for a ``reasonable'' standard as is 
currently set forth in regulation. We are finalizing a policy limiting 
application of the fixed-dollar payment threshold and gross premium 
percentage-based threshold to premium payments after coverage is 
effectuated. Issuers will be allowed to apply the fixed-dollar payment 
threshold and/or one of two percentage-based thresholds (but not both 
percentage-based thresholds). Issuers will be required to apply all 
chosen premium payment thresholds uniformly to all enrollees and 
without regard to their health status.
    We are finalizing a provision at Sec.  155.505(b) to codify an 
option for application filers as defined under Sec.  155.20 to file 
appeals on behalf of applicants and enrollees on the application 
filer's Exchange application.
    We are finalizing amendments at 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 
finalize amending Sec.  155.1090 with refinements to the standards for 
a request for the reconsideration of a denial of certification specific 
to the FFEs.
    We are finalizing that in addition to collecting the information 
and data currently provided by State Exchanges under Sec.  155.1200 to 
monitor performance and compliance, we would use the information and 
data that State Exchanges submit to increase transparency into Exchange 
operations and to promote program improvements. We anticipate publicly 
releasing the State Exchange spending on outreach (including 
Navigators), Open Enrollment call center metrics (call center volume, 
average wait time, average call abandonment rate), and website visits 
and visitors. We are stating in this final rule that we no longer 
intend to publicly release the State Exchanges' annual State-based 
Marketplace Annual Reporting Tools (SMARTs). In addition, we intend to 
only post those metrics for which we also have reasonably comparable 
data from Exchanges on the Federal platform.
4. 45 CFR Part 156
    We are finalizing 2026 benefit year FFE and SBE-FP user fee rates 
of 2.5 percent and 2.0 percent of total monthly premiums, respectively. 
We are also finalizing alternative 2026 benefit year FFE and SBE-FP 
user fee rates of 2.2 percent and 1.8 percent of total monthly 
premiums, respectively, if enhanced PTC subsidies,\16\ at the level 
currently enacted or at a higher level, are extended through the 2026 
benefit year by July 31, 2025.

1818 (2022) and are scheduled to expire after the 2025 calendar 
year.
---------------------------------------------------------------------------

    We are finalizing amendments to Sec.  156.80(d)(2)(i) to affirm 
that CSR loading practices that are permitted by State regulators are 
permissible under Federal law to the extent that they are actuarially 
justified and provided the issuer does not otherwise receive 
reimbursement for such CSR amounts.
    We are finalizing changes to the method for updating the AV 
Calculator, starting with the 2026 AV Calculator. Under this approach, 
for a plan year, we will only release a single, final version of the AV 
Calculator.
    We are finalizing 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 
response to comments requesting the expanded bronze metal level designs 
revert to the 50 percent coinsurance rate used in previous years, we 
have revised this plan design to maintain this consistency, instead of 
raising it to 60 percent for PY 2026, as proposed. We made several 
additional modifications to both sets of plan designs at the expanded 
bronze metal.
    In addition, we are finalizing amendments at 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, included prescription drugs, or a 
combination of some or all these factors.
    We are finalizing amendments at 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 adult vision benefit coverage categories 
under the non-standardized plan option limit in accordance with Sec.  
156.202(c)(1) through (3).
    We are finalizing conducting 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 are finalizing the proposal 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 are finalizing an amendment to Sec.  156.1220(a) to introduce a 
new materiality threshold for HHS-RADV appeals, such that we will 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 are finalizing amendments to Sec.  158.140(b)(4)(ii) to allow 
qualifying issuers to not adjust incurred claims by the net payments or 
receipts related to the risk adjustment program for MLR reporting and 
rebate calculation purposes beginning with the 2026 MLR reporting year 
(MLR reports due in 2027), with certain modifications. Specifically, we 
are finalizing that at the option of 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 are also finalizing 
an amendment to Sec.  158.103 to add a definition of ``qualifying 
issuer,'' with certain clarifications.
    We also are finalizing amendments to Sec.  158.240(c) to add an 
illustrative example of how qualifying issuers that opt to apply risk 
adjustment transfer amounts as described in Sec.  158.140(b)(4)(ii) 
will calculate the amount of rebate owed to each enrollee to accurately 
reflect how such issuers will 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) will apply to issuers 
that are not qualifying issuers and to qualifying issuers that do not 
opt to apply risk

adjustment transfer amounts as described in Sec.  158.140(b)(4)(ii).

III. Summary of the Provisions of the Proposed Regulations and Analysis 
of and Responses to Public Comments

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
    In the HHS Notice of Benefit and Payment Parameters for 2026 
proposed rule (89 FR 82308, 82317), we proposed to make a change to the 
calculation of the PAF starting in program year 2026. 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 two 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 
proposed 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 ARP is used to calculate 
the BHP payment. The 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.\17\ We also reserved the right that 
in the case an appropriation for CSR payments is made for a future 
year, to determine whether and how to modify the PAF in the payment 
methodology.
---------------------------------------------------------------------------

    \17\ <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 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.\18\ The median adjustment for silver 
level QHPs is referred to as the nationwide median adjustment.
---------------------------------------------------------------------------

    \18\ 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

[[Page 4434]]

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 percent) / (1 + 1 percent) (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.\19\ 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.
---------------------------------------------------------------------------

    \19\ See the Federal Funding Methodology for Program Year 2023 
and Changes to the Basic Health Program Payment Notice Process at 87 
FR 77722, 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.\20\ 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.
---------------------------------------------------------------------------

    \20\ Id. at 77731-32.
---------------------------------------------------------------------------

    We proposed 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 2 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 \21\ and to avoid such an 
overpayment, we proposed the following changes to the PAF:
---------------------------------------------------------------------------

    \21\ 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 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

[[Page 4435]]

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.
    We noted in the proposed rule (89 FR 82319) that 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 also noted in the proposed rule (89 FR 82319) that 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 requested comments on this approach 
or alternative approaches to calculating the PAF.
    After consideration of comments and for the reasons outlined in the 
proposed rule and this final rule, including our responses to comments, 
we are finalizing the approach to calculating the PAF as proposed. We 
summarize and respond to public comments received on the proposed 
change to the calculation of the PAF below.
    Comment: Several commenters were supportive of the change to adjust 
the PAF for BHP in program years in which States have not fully 
implemented BHP.
    Response: We appreciate these comments in support of the proposed 
change.
    Comment: One commenter noted ``relying on silver CSR loads from 
2018 in the development of the population adjustment factor may not 
reflect actual silver loads because these 2018 premiums are based on 
experience from a time when CSRs were fully funded,'' while also 
acknowledging there are other factors ``including state-specified 
loads, the impact of States' 1332 waivers, the effects of the COVID-19 
pandemic and related Medicaid coverage policies, and other factors'' 
that may affect these adjustments in States.
    Response: We acknowledge that there are limitations to relying on 
the 2018 CSR loads for calculation of the PAF. We also agree that other 
factors that may affect CSR loads and these factors complicate updating 
the PAF. We did not propose and are not making any changes to the 
standard calculation of the PAF in this final rule.
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,\22\ 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,\23\ for the 2026 payment 
methodology and all subsequent years, we proposed 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 sought comment on this approach.

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

    After consideration of comments and for the reasons outlined in the 
proposed rule and this final rule, including our responses to comments, 
we are finalizing this policy as proposed. We summarize and respond to 
public comments received on the proposed clarification of the correct 
premiums to use below.
    Comment: Several commenters were supportive of the clarification 
for which second lower cost silver plan premiums to use in these cases 
for the purposes of calculating the Federal BHP payment.
    Response: We appreciate these comments in support of the proposed 
change.
    Comment: Two commenters noted that in one State that has operated a 
BHP, the State is using a different silver plan premium (the third 
lowest cost silver plan premium) in cases when there are two or more 
second lowest cost silver plan premiums in an area. Commenters noted 
that using the proposed approach would present operational challenges 
for the State. The commenters requested flexibility on this in the BHP 
payment methodology.
    Response: We appreciate the comments and understand that there may 
be some operational issues; however, we believe that these issues can 
be easily addressed, and we note that other BHP States have been able 
to determine premiums in accordance with these requirements. In 
addition, we do not believe there is any basis to use any premiums 
other than the second lowest cost silver plans (even if there are two 
or more in an area) for the purposes of the BHP payment methodology.

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.\24\ 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.
---------------------------------------------------------------------------

    \24\ 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.\25\ The Federal Government's 2025 fiscal year began on 
October 1, 2024. Therefore, the HHS-operated risk adjustment program is 
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).
---------------------------------------------------------------------------

    \25\ OMB. (2024). OMB Report to the Congress on the BBEDCA 251A 
Sequestration for Fiscal Year 2025. <a href="https://www.whitehouse.gov/wp-content/uploads/2024/03/BBEDCA_251A_Sequestration_Report_FY2025.pdf">https://www.whitehouse.gov/wp-content/uploads/2024/03/BBEDCA_251A_Sequestration_Report_FY2025.pdf</a>.
---------------------------------------------------------------------------

    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),\26\ 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 the 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.
---------------------------------------------------------------------------

    \26\ Public Law 99-177, 99 Stat. 1037 (1985).
---------------------------------------------------------------------------

    Additionally, we note that the Infrastructure Investment and Jobs 
Act \27\ amended section 251A(6) of the BBEDCA and extended 
sequestration for the HHS-operated risk adjustment program through 
fiscal year 2031 at a rate of 5.7 percent per fiscal year.\28\
---------------------------------------------------------------------------

    \27\ Public Law 117-58, 135 Stat. 429 (2021).
    \28\ 2 U.S.C. 901a.
---------------------------------------------------------------------------

    One comment was received on this section of the proposed rule that 
acknowledges the fiscal year 2025 sequestration rate. Therefore, after 
consideration of this comment and for reasons outlined in the proposed 
rule and this final rule, the HHS-operated risk adjustment program will 
sequester payments made from fiscal year 2025 resources at a rate of 
5.7 percent.
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 HCCs) producing a risk score. The State payment transfer 
formula \29\ 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,\30\ and prescription drug categories (RXCs) 
beginning with the 2018 benefit year.\31\ 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 \32\ applicable 
to certain severity and transplant HCCs.\33\
---------------------------------------------------------------------------

    \29\ 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.
    \30\ For the 2017 through 2022 benefit years, there was a set of 
11 binary enrollment duration factors in the adult models that 
decreased 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.
    \31\ 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.
    \32\ See Table 4 in the proposed rule for a list of draft 
factors in the adult models, and Table 5 in the proposed rule for a 
list of draft factors in the child models.
    \33\ See 87 FR 27224-28. Also see Table 6 in the proposed rule.
---------------------------------------------------------------------------

    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 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
    In the HHS Notice of Benefit and Payment Parameters for 2026 
proposed rule (89 FR 82308, 82320 through 82321), we proposed to 
recalibrate the 2026 benefit year HHS risk adjustment models with the 
2020, 2021, and 2022 enrollee-level EDGE data. In the proposed rule, we 
noted the history of recalibrating the risk adjustment models, the 
transition to use of enrollee-level EDGE data for this purpose, and why 
we use 3 years of blended data for recalibration.\34\ Given this 
history and reasoning, we proposed to determine coefficients for the 
2026 benefit year 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\ We sought

[[Page 4437]]

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.
---------------------------------------------------------------------------

    \34\ See 89 FR 82308, 82320-21.
    \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 
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 2026 benefit year models are appropriate for the most recent 
changes in cost of care that we have seen.
---------------------------------------------------------------------------

    After consideration of comments and for the reasons outlined in the 
proposed rule and our responses to comments, we are finalizing the 
approach to use the 2020, 2021 and 2022 enrollee-level EDGE data to 
calculate the 2026 benefit year coefficients as proposed. We summarize 
and respond to public comments received on the proposed enrollee-level 
EDGE data to be used for HHS risk adjustment model recalibration for 
the 2026 benefit year below. Because we were unable to complete the 
calculations for the final coefficients in time to publish them in this 
final rule, we will publish the final 2026 benefit year coefficients in 
guidance after the publication of this final rule consistent with Sec.  
153.320(b)(1)(i). We will release this guidance by the spring of 2025, 
in time for rate setting for the 2026 benefit year.
    Comment: A few commenters supported utilizing the 2020, 2021, and 
2022 enrollee-level EDGE data to recalibrate the HHS risk adjustment 
models for the 2026 benefit year as proposed. Other commenters opposed 
or noted concern about using these years of enrollee-level EDGE data 
due to concerns about the potential impact of the COVID-19 PHE on 2020 
and 2021 benefit year enrollee-level EDGE data.
    Response: We are finalizing the use of the 2020, 2021, and 2022 
enrollee-level EDGE data to recalibrate the 2026 benefit year HHS risk 
adjustment models as proposed. As described in the proposed rule (89 FR 
82308, 82320) and detailed further below, our analyses found the 2020 
and 2021 benefit year enrollee-level EDGE data is sufficiently similar 
to prior years of enrollee-level EDGE data such that exclusion of these 
data years from the risk adjustment model recalibration is not 
warranted.
    We recognize that if a benefit year of enrollee-level EDGE data has 
significant changes that differentially impact certain conditions or 
populations relative to others or is sufficiently anomalous relative to 
expected future patterns of care, we should carefully consider what 
impact that benefit year of data could have if it is used in the annual 
recalibration of the HHS risk adjustment models.\36\ This includes 
consideration of whether to exclude or adjust that benefit year of data 
to increase the models' predictive validity or otherwise limit the 
impact of anomalous trends. For this reason, as described in the 2026 
Payment Notice proposed rule,\37\ we conducted extensive analysis on 
the 2020 benefit year enrollee-level EDGE data to consider its 
inclusion in the recalibration of the 2024 benefit year risk adjustment 
models. For example, in the 2024 Payment Notice proposed rule \38\ and 
final rule \39\ we discussed our analysis of the 2020 benefit year data 
to identify possible impacts of the COVID-19 PHE.\40\ Likewise, when we 
conducted recalibration of the 2025 benefit year risk adjustment 
models, we conducted similar analyses on the 2021 benefit year 
enrollee-level EDGE data as we did to the 2020 benefit year enrollee-
level EDGE data to examine the potential impact of the COVID-19 
PHE.\41\ We did not find any notable anomalous trends, and determined 
that deviations identified in 2020 or 2021 benefit year data were 
within the expected level for any individual data year. Further, we 
believe the blending of the coefficients from the separately solved 
models for benefit years 2020 and 2021 with benefit year 2022 for 
purposes of the 2026 benefit year model recalibration sufficiently 
stabilizes any differences resulting from the COVID-19 PHE in the 2020 
or 2021 datasets. As the 2020 and 2021 benefit years' enrollee-level 
EDGE data used to recalibrate the 2025 benefit year risk adjustment 
models are identical to the 2020 and 2021 enrollee-level EDGE data used 
to recalibrate the 2026 benefit year risk adjustment models, the 
analyses and conclusions discussed in prior rulemaking equally apply to 
the recalibration of the risk adjustment models for the 2026 benefit 
year.
---------------------------------------------------------------------------

    \36\ Since the start of model calibration for the HHS risk 
adjustment models in benefit year 2014, the COVID-19 PHE has been 
the only such situation to date. Other events and policy changes 
have not risen to the same level of uniqueness or potential impact.

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

    Comment: One commenter noted decreases in the risk adjustment model 
R-squared values for the 2022 benefit year enrollee-level EDGE data 
relative to prior benefit years as presented in Table 10 of the 
proposed rule.\42\ This commenter requested information regarding any 
analysis HHS has conducted concerning the reduction in this model 
performance statistic.
---------------------------------------------------------------------------

    \42\ 89 FR 82308, 82347.
---------------------------------------------------------------------------

    Response: First, as demonstrated by Table 10 of the proposed 
rule,\43\ each individually solved model that contributes to the 
blended HHS risk adjustment models has an R-squared statistic within 
the expected range for concurrent claims-based risk scoring models \44\ 
such as the models used for the HHS-operated risk adjustment program. 
Nevertheless, we are aware of and intend to continue monitoring the 
slight decrease in the R-squared values for the HHS risk adjustment 
models over the past few years of enrollee-level EDGE data which 
indicates that the models are explaining slightly less of the variation 
in plan liability for the 2022 benefit year enrollee-level EDGE data 
compared to prior benefit years of enrollee-level EDGE data. In our 
quality control assessments of the recalibration process for the 
proposed draft 2026 benefit year coefficients, we explored two possible 
explanations for this decrease in R-squared values--a shift in 
enrollment and the presence of outlier enrollees with very high costs 
in the enrollee-level EDGE data.
---------------------------------------------------------------------------

    \43\ See 89 FR 82308, 82347.
    \44\ See Hileman, G., & Steele, S. (2016). Accuracy of Claims-
Based Risk Scoring Models. Society of Actuaries. <a href="https://www.soa.org/4937b5/globalassets/assets/files/research/research-2016-accuracy-claims-based-risk-scoring-models.pdf">https://www.soa.org/4937b5/globalassets/assets/files/research/research-2016-accuracy-claims-based-risk-scoring-models.pdf</a>.
---------------------------------------------------------------------------

    Our analysis found that the largest percentage decreases in R-
squared values between the 2022 benefit year and the 2019 (or 2020) 
\45\ benefit year of enrollee-level EDGE data for adult enrollees were 
for enrollees without HCCs, enrollees with only 1 month of enrollment, 
and new enrollees (that is, enrollees new to an issuer, whose system 
identifier was not present for the issuer in the prior year).\46\ We 
interpret these results to be consistent with a hypothesis that new 
enrollees and a greater proportion of relatively healthier enrollees in 
2022 were partially

[[Page 4438]]

responsible for a decrease in model R-squared values between the 2022 
benefit year and the 2019 through 2021 benefit years of enrollee-level 
EDGE data, in that the R-squared value decreases are largest for 
subgroups that are likely to contain more new enrollees or are 
difficult to predict, for example, new enrollees to an issuer and 
enrollees without HCCs.
---------------------------------------------------------------------------

    \45\ HHS was unable to incorporate an analysis of new enrollees 
for the 2019 benefit year of enrollee-level of EDGE data at the time 
of the analysis of R-squared changes. As such, R-squared changes for 
new enrollees only considered the difference between 2020 benefit 
year and 2022 benefit year R-squared values.
    \46\ Ibid.
---------------------------------------------------------------------------

    Likewise, our analysis found that the removal of outlier enrollees 
always resulted in an increase in R-squared values and the impacts were 
notably higher for 2020, 2021, and 2022 enrollee-level EDGE data than 
for 2019 enrollee-level EDGE data. We interpret these results to imply 
that recent data years have exhibited more influential high-cost 
enrollees. However, we do not see the presence of cost outliers in the 
enrollee-level EDGE data to be problematic at this time because we 
generally expect the number of cost outliers to vary from year to year, 
and we did not find evidence that suggests a clear data error exists 
related to any of these outliers.
    In short, although we were able to identify likely contributing 
factors to the observed slight decrease in R-squared values and will 
continue to monitor the R-squared values in the future, the R-squared 
values for 2026 benefit year risk adjustment model recalibration remain 
high and within the expected range of R-squared values for the type of 
model used for the HHS-operated risk adjustment program. We remain 
confident the HHS risk adjustment models continue to operate 
effectively and appropriately predict plan liability for an average 
enrollee.
    After consideration of comments and for the reasons outlined in the 
proposed rule, this final rule, the 2024 Payment Notice, the 2025 
Payment Notice,\47\ and our responses to comments above, we are 
finalizing this approach as proposed. However, to account for the 
incorporation of the human immunodeficiency virus (HIV) pre-exposure 
prophylaxis (PrEP) affiliated cost factor (ACF) with the generic drug 
exclusion and hierarchy specifications finalized in this rule, we were 
unable to complete the calculations for the final coefficients in time 
to publish them in this final rule. Therefore, consistent with Sec.  
153.320(b)(1)(i), we are finalizing the use of the 2020, 2021 and 2022 
enrollee-level data to calculate the 2026 benefit year coefficients and 
will publish the final coefficients for the 2026 benefit year in 
guidance after the publication of this final rule. We will release this 
guidance in time for rate setting for the 2026 benefit year.

b. Pricing Adjustment for the Hepatitis C Drugs
    In the HHS Notice of Benefit and Payment Parameters for 2026 
proposed rule (89 FR 82308, 82321), we proposed that beginning with the 
2026 benefit year, we would begin phasing out the market pricing 
adjustment \48\ 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 \49\ 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.\50\ 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.\51\ For the reasons 
and history described in the proposed rule, we proposed to adopt a 
multi-year phase out approach to transition the Hepatitis C drugs' 
trending to move away from the current unique market pricing adjustment 
for these drugs and align Hepatitis C drugs' trending with the trending 
approach for specialty drugs.\52\ To begin this transition for the 2026 
benefit year HHS risk adjustment models, we proposed 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). 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, we proposed to 
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. We proposed 
to continue this approach 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, 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 sought comment on our proposal to begin to phase out the 
Hepatitis C drugs 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.
    After consideration of comments and for the reasons outlined in the 
proposed rule and this final rule, including our responses to comments, 
we are finalizing this policy as proposed. We summarize and respond to 
public comments received on the proposal to begin to phase out the 
market pricing adjustment for Hepatitis C drugs starting with the 2026 
benefit year below.
    Comment: Many commenters supported the proposal to begin 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. Many 
of these commenters agreed with HHS' assessment that the cost trend for 
Hepatitis C drugs has begun to rise alongside the expected cost of 
other specialty drugs. A couple of commenters recommended close 
monitoring of costs and utilization of Hepatitis C drugs to ensure that 
access to these drugs is not interrupted for enrollees.
    Response: We are finalizing the phasing out of the market pricing 
adjustment for Hepatitis C drugs starting with the 2026 benefit year as 
proposed. We agree with commenters that the cost

[[Page 4439]]

trend for Hepatitis C drugs has changed and resulted in the need to 
reexamine the treatment of these drugs in the HHS risk adjustment 
models, including consideration of phasing out the market pricing 
adjustment for these drugs. We also note that the policy adopted in 
this final rule to phase out the market pricing adjustment for these 
drugs will allow Hepatitis C drug costs to increase as appropriate 
alongside other specialty drugs in the simulation of plan liability 
used for annual HHS risk adjustment model recalibration. Starting this 
transition beginning with the 2026 benefit year and appropriately 
accounting for price increases of Hepatitis C drugs in the HHS risk 
adjustment models alongside other specialty drugs in the simulation of 
plan liability responds to these observed emerging trends and will 
better reflect the actuarial risk of an issuer's population, especially 
for issuers that attract a large number of enrollees using Hepatitis C 
drugs, helping to prevent adverse selection and the associated perverse 
incentives. As such, we are finalizing the policy to begin phasing out 
of the Hepatitis C market pricing adjustment starting with the 2026 
benefit year recalibration of the HHS risk adjustment models as 
proposed, but we will also continue to monitor costs and utilization of 
drugs, including Hepatitis C drugs, as part of our ongoing efforts to 
examine ways to continually improve the HHS risk adjustment models for 
future benefit years.
    Comment: One commenter requested that HHS continue to review the 
costs associated with specialty drugs and consider whether market 
pricing adjustments may be warranted for GLP-1 drugs, gene therapies, 
or other unique, high-cost drugs that may drive the cost of treating a 
particular condition in a given benefit year significantly higher than 
those reflected in the enrollee-level EDGE data years used in 
recalibration for that benefit year. One commenter noted recently 
available expensive gene therapies for sickle cell disease as an 
example of this phenomenon and requested that HHS consider a market 
pricing adjustment for sickle cell disease treatments.
    Response: We did not propose to change the treatment of high-cost 
drugs, such as GLP-1 drugs, sickle cell disease treatments, or other 
gene and cellular therapies, in the 2026 benefit year HHS risk 
adjustment models and are not finalizing such updates in this final 
rule. As we discussed in the 2022 Payment Notice \53\ and 2025 Payment 
Notice,\54\ we recognize that the data used to recalibrate the HHS risk 
adjustment models lag by several benefit years behind the applicable 
benefit year for risk adjustment and therefore may not account for the 
costs of new, expensive drugs, such as gene therapy drugs, that are 
expected to be available in the market by the applicable benefit year 
of risk adjustment. Thus, we continue to consider ways that we could 
better account for high-cost drugs in the risk adjustment models and, 
as part of this effort, analyze new data as they become available.
---------------------------------------------------------------------------

    \53\ See 86 FR 24140, 24163.
    \54\ See 89 FR 26218, 26247-48.
---------------------------------------------------------------------------

    With specific regard to new gene therapies for sickle cell disease, 
when we were previously analyzing the changes to the sickle cell 
disorder related HCCs in the 2025 benefit year risk adjustment 
models,\55\ we considered whether to add an RXC for existing high-cost 
sickle cell drugs and new gene therapy treatments, but determined that 
we need to continue to analyze the evolution and availability of drug 
treatments for sickle cell disease. Specifically, the new gene therapy 
drugs for sickle cell disease were not approved for the market until 
December 2023.\56\ Therefore, the first full year of claims data in 
which these new sickle cell disease treatments may be reflected will 
not be available until the 2024 benefit year enrollee-level EDGE data 
is available. We therefore continue to find that we do not have enough 
information at the present time to account for these treatments in the 
HHS risk adjustment models because of the general lack of data on the 
utilization and cost of gene therapy drugs for sickle cell disease in 
the individual, small group, and merged markets. We are committed to 
continuing to analyze new data as they become available and, consistent 
with Sec.  153.320(b)(1), we would propose the addition of any market 
pricing adjustments or other changes to the risk adjustment models to 
account for these treatments through notice-and-comment rulemaking, as 
appropriate. We also note that if an enrollee in an issuer's risk 
adjustment covered plan has claims for gene therapy, other high-cost 
drugs, or other expensive treatments, that enrollee would be eligible 
for the high-cost risk pool payments if claims for that enrollee are 
over $1 million.\57\

    \57\ For example, the new sickle cell gene therapy treatments 
are expected to exceed the high-cost risk pool payment threshold.

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

    Considering the absence of adequate data, we did not propose and 
are not finalizing a new market pricing adjustment or other model 
adjustments for sickle cell gene therapy drugs for the 2026 benefit 
year. We intend to continue to assess sickle cell gene therapy drugs 
and other high-cost drugs to consider whether model updates for future 
benefit years are warranted.
    We also intend to work with interested parties to continue to 
analyze plan liability for sickle cell disease and the impact of gene 
and cell therapy treatments, as well as explore the availability of 
alternative data sources that could be used to monitor utilization and 
costs outside of currently available enrollee-level EDGE data.
    As explained in the 2025 Payment Notice (89 FR 26249), we also 
recently examined the treatment of GLP-1 drugs in the HHS risk 
adjustment models using the 2022 benefit year enrollee-level EDGE data 
and found that, at this time, a change was not warranted to the current 
mapping of GLP-1 drugs to RXC 07 (Anti Diabetic Agents, Except Insulin 
and Metformin Only).\58\ We understand GLP-1 drug utilization patterns 
are changing and will continue to assess these trends as additional 
benefit years of enrollee-level EDGE data become available for 
potential targeted refinements to the HHS risk adjustment models in 
future benefit years, as appropriate.
---------------------------------------------------------------------------

    \58\ As background, RXC 07 (Anti Diabetic Agents, Except Insulin 
and Metformin Only) is a pharmacotherapeutic class of drugs, which 
contains a broad array of anti-diabetic medications that vary in 
cost. RXC 07 (Anti Diabetic Agents, Except Insulin and Metformin 
Only) does not include all GLP-1 drugs currently on the market; 
drugs that carry an FDA indication for chronic weight management are 
excluded from RXC 07 (Anti Diabetic Agents, Except Insulin and 
Metformin Only). The RXC 07 (Anti Diabetic Agents, Except Insulin 
and Metformin Only) coefficient in the HHS risk adjustment adult 
models is meant to reflect the average enrollee cost for individuals 
being treated by any of the drugs in this class.
---------------------------------------------------------------------------

    Comment: One commenter requested additional information on how HHS 
defines generic and specialty drugs and what trend assumptions HHS uses 
for each of these two categories, asserting that this information would 
help interested parties better evaluate the proposal to begin to phase 
out the Hepatitis C market pricing adjustment against costs experienced 
by issuers.
    Response: Since the 2017 benefit year, we have subdivided 
expenditures into traditional drugs, specialty drugs, medical services, 
and preventive

[[Page 4440]]

services and determine trend factors separately for each category of 
expenditure.\59\ In determining these trend factors, we consult our 
actuarial experts, review relevant URRT submission data, analyze 
multiple years of enrollee-level EDGE data, and consult NHEA data as 
well as external reports and documents \60\ published by third parties. 
As described in the 2024 Payment Notice,\61\ in this process, we aim to 
determine trends that reflect changes in cost of care rather than gross 
growth in expenditures. We believe the trend factors we used for each 
expenditure category for the 2026 benefit year are appropriate for the 
most recent changes in cost of care that we have seen in the market. We 
further note that, for the purposes of annual risk adjustment model 
recalibration activities, our definitions of what drugs qualify as 
either traditional (for example, low-cost and generic drugs) or 
specialty are also informed by consultations with actuarial experts and 
by reviewing price data for these drugs. Specific thresholds and 
criteria may vary according to the class of drugs or the conditions 
they are intended to treat, but we generally use the Part D specialty-
tier cost threshold, which is updated periodically, to differentiate 
between traditional and specialty drugs.\62\

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

    After consideration of comments and for the reasons outlined in the 
proposed rule and this final rule, including our responses to comments 
above, we are finalizing the proposal to begin phasing out the market 
pricing adjustment for Hepatitis C drugs starting with the 2026 benefit 
year, as proposed. However, to account for the incorporation of the 
PrEP ACF with the generic drug exclusion and hierarchy specifications 
finalized in this final rule, we were unable to complete the 
calculations for the final coefficients in time to publish them in this 
final rule. Therefore, consistent with Sec.  153.320(b)(1)(i), we will 
publish the final coefficients for the 2026 benefit year in guidance 
after the publication of this final rule. We will release this guidance 
in time for rate setting for the 2026 benefit year.
c. Inclusion of Pre-Exposure Prophylaxis (PrEP) in the HHS Risk 
Adjustment Adult and Child Models as an Affiliated Cost Factor (ACF)
    In the HHS Notice of Benefit and Payment Parameters for 2026 
proposed rule (89 FR 82308, 82323), we proposed 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. As proposed, the 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 medical 
condition and would change our current policy that models the costs of 
PrEP alongside other preventive services.
    As explained in the proposed rule (89 FR 82324), as a general 
principle, we currently incorporate preventive services (including PrEP 
\63\) into 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. In addition to PrEP drugs, like other 
preventive services,\64\ 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.\65\
---------------------------------------------------------------------------

    \63\ See 85 FR 28164, 29185-87.
    \64\ 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.
    \65\ See 86 FR 24140, 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 more accurately assess the 
actuarial risk and costs associated with PrEP in the HHS risk 
adjustment models. In this regard, we stated in the proposed rule (89 
FR 82324) that because of PrEP's high costs relative to other 
preventive services, PrEP services can pose a unique risk of adverse 
selection to the extent that utilization of PrEP services differs 
between plans. Our analysis of 2022 benefit year enrollee-level data 
\66\ found that the costs of PrEP services remained high, in contrast 
to our initial assumptions about expected pricing decreases as generics 
entered the market, and 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. 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 proposed to incorporate 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 
proposed new factor would not indicate the presence of a specific 
active medical condition, we referred to the proposed new type of 
factor as an ``affiliated cost factor'' (ACF), thereby distinguishing 
this new type of factor from RXCs and HCCs. Furthermore, we proposed a 
set of seven principles to guide our development of any new ACF 
variable.
---------------------------------------------------------------------------

    \66\ 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 27208, 27241-51), 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 recent analysis reflects our earliest 
opportunity to reliably detect differences in prevalence within 
rating areas for any medical and prescription drug expenditures, 
including PrEP.
---------------------------------------------------------------------------

    We stated in the proposed rule (89 FR 82324) that in developing an 
ACF variable reflecting PrEP, we considered whether PrEP satisfies 
those principles and what approaches were necessary to appropriately 
balance all seven principles. As described in the proposed rule, a PrEP 
ACF would easily satisfy the principles of clinical meaningfulness and 
specificity,

[[Page 4441]]

meaningful and predictable costs,\67\ sufficient sample size, and low 
risk of inappropriate prescribing. However, we also stated in the 
proposed rule that that the creation of a PrEP ACF variable would 
require further careful consideration in assessing the other three 
proposed principles: specifically, the principles of hierarchical 
factor definitions, monotonicity, and mutually exclusive 
classification.
---------------------------------------------------------------------------

    \67\ As discussed later in this section, it may be appropriate 
to remove generic drugs to ensure homogeneity of costs within a PrEP 
ACF.
---------------------------------------------------------------------------

    We stated in the proposed rule (89 FR 82327) that to address the 
HHS risk adjustment adult modeling concerns we identified regarding 
these three principles; we considered 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. 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 the issuer's EDGE server. Alternatively, we explained we 
could place the PrEP ACF in a hierarchy with RXC 1 but define no 
hierarchical restrictions between PrEP and HCC 1 (HIV/AIDS). This 
alternative would allow 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. We solicited comments on addressing these hierarchy, 
monotonicity, and mutual exclusivity concerns, and both alternative 
approaches designed to address those concerns.
    We also sought comment 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 sought comment 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 \68\ or differences in medication 
adherence for PrEP). Furthermore, we sought comment regarding the 
principles to guide inclusion of potential ACF factors and the 
alternative approaches for defining a PrEP ACF's hierarchical 
relationship to HCC 1 and RXC1 to address the concerns related to 
hierarchical factor definitions, violations of monotonicity, and 
violations of mutually exclusive classification in the HHS risk 
adjustment adult models.
---------------------------------------------------------------------------

    \68\ 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 
alafenamide. AIDS. 2022 Dec 1;36(15):2225-2227. doi: 10.1097/
QAD.0000000000003401. See, also, Krakower, D. and Marcus, J.L. 
Commercial Determinants of Access to HIV Preexposure Prophylaxis.

jamanetworkopen.2023.42759. See, also, McManus, K.A., et al.

jamanetworkopen.2023.42781.
---------------------------------------------------------------------------

    Additionally, we solicited comments on whether generic versions of 
PrEP medication should be excluded from the definition of the proposed 
ACF for PrEP. As we stated in the proposed rule (89 FR 82326), we found 
that a large disparity exists between the costs of generic PrEP 
medication and the costs of brand name PrEP medication.\69\ We 
explained that due to this disparity, if we include all PrEP 
medications in the definition of an ACF, the estimated coefficient 
would likely lead to overprediction for enrollees receiving generic 
medications and underprediction for enrollees receiving brand name 
medications. Therefore, an exclusion of low-cost generics from the PrEP 
ACF could 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.\70\
---------------------------------------------------------------------------

    \69\ See, supra, note 53.
    \70\ We previously excluded generic drugs from RXC 9, Immune 
Suppressants and Immunomodulators, due to concern over patient 
access and health plan selection behavior. See the 2019 Payment 
Notice (83 FR 16942).
---------------------------------------------------------------------------

    Lastly, we sought comment concerning whether there are any similar 
medical expenses or services that we should consider for potential new 
ACFs alongside PrEP.
    After consideration of comments and for the reasons outlined in the 
proposed rule and this final rule, including our responses to comments, 
we are finalizing the addition of PrEP as an ACF in the HHS risk 
adjustment adult and child models, but are excluding generic versions 
of PrEP from the ACF at this time, and are placing the PrEP ACF in the 
adult models in a hierarchy below RXC 1 (Anti-HIV Agents) without 
defining any hierarchical relationship between the PrEP ACF and HCC 1 
(HIV/AIDS). In the child models, which do not contain RXCs, we are 
finalizing the placement of the PrEP ACF in a hierarchy with HCC 1. We 
summarize and respond to public comments received on the proposed 
addition of PrEP as an ACF in the HHS risk adjustment adult and child 
models starting with the 2026 benefit year below.
    Comment: Many commenters supported the proposal to add PrEP to the 
HHS risk adjustment adult and child models as an ACF. Many of these 
commenters noted agreement with HHS' determination that PrEP presents a 
unique risk of adverse selection among preventive services and that the 
addition of PrEP to the HHS risk adjustment adult and child models 
would mitigate perverse incentives for issuers to minimize their 
exposure to enrollees who can benefit from PrEP despite the mandate to 
cover preventive services with no enrollee cost sharing. Several 
commenters stated that this addition to the HHS risk adjustment adult 
and child models will better align issuers' incentives with the public 
health benefit of preventing HIV transmission. A few commenters 
acknowledged that PrEP may be appropriate to include in the HHS risk 
adjustment adult and child models but noted doubt that a new class of 
factors (that is, ACFs) was necessary.
    Response: We agree with commenters that PrEP should be properly 
represented in the HHS risk adjustment adult and child models to 
mitigate the potential for adverse selection and appreciate the support 
for the addition of a new PrEP ACF to these models beginning with the 
2026 benefit year. As explained in the proposed rule (89 FR 82308, 
82323-24), we believe that creating a new class of factors is necessary 
and appropriate at this time to capture actuarial risks and costs that 
may contribute to adverse selection but are not indicative of an active 
medical condition, as is the case with PrEP, and therefore would not be 
reflected in the

[[Page 4442]]

HCC and RXC factors used in the HHS risk adjustment models.
    Although this new ACF class of model factors is guided by similar 
principles \71\ for inclusion as the existing RXC class of model 
factors,\72\ we feel that it is conceptually appropriate to distinguish 
between these two classes. As stated in the 2018 Payment Notice,\73\ 
RXCs were specifically incorporated into the HHS risk adjustment models 
as separate factors from HCCs (which indicate the presence of a 
diagnosis directly) to impute a missing diagnosis or indicate severity 
of a diagnosis. Because the PrEP ACF (and any potential future ACFs) 
are not intended to be related to a diagnosis for any medical 
condition, we believe it is appropriate to distinguish such model 
factors from RXCs and HCCs.

    Comment: One commenter opposed the proposal to add PrEP to the HHS 
risk adjustment adult and child models as an ACF on the basis that the 
commenter believes including PrEP in the HHS risk adjustment adult and 
child models is discriminatory, expressing a belief that risk 
adjustment and the assignment of risk scores to enrollees based on 
health conditions is discriminatory in general.
    Response: HHS takes seriously our obligation to protect individuals 
from discrimination and generally disagrees that the use of factors 
based on enrollees' age, sex, and health conditions or utilization of 
services and treatments in risk adjustment is inappropriate. Consistent 
with section 1343 of the ACA, the HHS-operated risk adjustment program 
reduces the incentives for issuers to avoid higher-than-average risk 
enrollees, such as those with chronic conditions, by using charges 
collected from issuers that attract lower-than-average risk enrollees 
to provide payments to health insurance issuers that attract higher-
than-average risk enrollees. The ACA limits issuers' ability to 
establish or charge premiums on the basis of age and prohibits issuers' 
ability to do so on the basis of sex or any individual health 
characteristic other than tobacco use.\74\ However, the cost of care 
for and actuarial risk of enrollees is, in part, correlated with their 
age, sex, health conditions (or severity thereof), and likelihood to 
utilize services and treatments. As such, without the inclusion of 
factors related to age, sex, health conditions, and use of services and 
treatments in the HHS risk adjustment models, some issuers would be 
incentivized to design plans that are less attractive to potential 
enrollees whose age-sex category, health conditions, or use of services 
and treatments is predicted to create a higher liability for the 
issuer. The various factors in the HHS risk adjustment models help 
alleviate this incentive by ensuring that the actuarial risk of an 
issuers' enrollee population in a State market risk pool, including 
issuers that enroll a higher-than-average proportion of enrollees who 
fall into a high-cost age-sex category or are likely utilizers of high-
cost preventive services (PrEP, for example), are appropriately 
assessed as part of the calculations under the State payment transfer 
formula. The use of factors associated with age, sex, health 
conditions, and the use of services and treatments (including expensive 
preventive services, such as PrEP) in the HHS risk adjustment models is 
therefore necessary, appropriate, and helps reduce the likelihood that 
discrimination based on any of these factors will occur with respect to 
health insurance coverage issued or renewed in the individual and small 
group (including merged) markets.

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

    Comment: One commenter opposed the proposal due to concerns that 
the addition of ACFs would increase risk adjustment model complexity. A 
few commenters urged caution in implementing the proposal or requested 
that HHS implement the addition of the PrEP ACF on a pilot basis. A few 
commenters requested a technical paper be published on the ACF concept.
    Response: We appreciate commenters' interest in carefully 
considering the impact of the addition of a PrEP ACF to the HHS risk 
adjustment adult and child models. We will continue to monitor the 
performance of the HHS risk adjustment models, including the impact of 
the new PrEP ACF. Although the HHS risk adjustment models are made more 
complex by the addition of any new model factor, we believe that the 
seven principles for considering new ACFs discussed in the proposed 
rule,\75\ as well as the existing principles for consideration of HCCs 
\76\ and RXCs,\77\ are sufficient to ensure that new model factors are 
only added when appropriate. In particular, we note that the addition 
of the PrEP ACF satisfies the principles of clinical meaningfulness and 
specificity, meaningful and predictable costs, sufficient sample size, 
and low risk of inappropriate prescribing. Therefore, we determined 
that the addition of the PrEP ACF is likely to improve the predictive 
validity of the models with respect to the portion of the enrollee 
population that are eligible for PrEP. With the specifications 
finalized in this rule to address the principles of hierarchical factor 
definitions, monotonicity, and mutually exclusive factor definitions, 
we believe that the benefits of adding a new PrEP ACF outweighs the 
concerns about model complexity. In addition, our recent analysis of 
2022 benefit year enrollee-level EDGE data confirmed there is 
sufficiently robust data to justify the addition of the PrEP ACF and 
calculate its coefficients for the HHS risk adjustment adult and child 
models beginning with the 2026 benefit year such that a pilot period 
for the PrEP ACF is unnecessary.

    As always, as part of our ongoing efforts to continually improve 
the precision of the HHS risk adjustment models, we will seek input 
from interested parties through notice-and-comment rulemaking or other 
appropriate vehicles (including technical papers, as appropriate) on 
potential changes to the HHS risk adjustment models, including any 
potential new ACFs we may consider in the future. However, in light of 
the rationale and data discussed in the proposed rule, and in response 
to the comments in support of adding the PrEP ACF to the HHS risk 
adjustment adult and child models beginning with the 2026 benefit year, 
we do not believe a technical paper is warranted before finalizing the 
addition of the PrEP ACF to the HHS risk adjustment adult and child 
models.

[[Page 4443]]

    Comment: Several commenters expressed a preference for excluding 
generic drugs from the definition of the PrEP ACF, noting the vast 
difference in prices between brand name and generic drugs. One 
commenter noted that their experience showed that prices for brand name 
PrEP drugs can be as much as 100 times the cost of generic PrEP drugs. 
A few commenters stated that excluding generics would better support 
patients as advances in PrEP come to market, with a few commenters 
specifically noting that newer branded forms of PrEP drugs that are 
more effective, more tolerable, and long-acting will likely be the 
predominant form of PrEP in the near future. Furthermore, a few 
commenters were concerned that including generics in the PrEP ACF 
definition would overcompensate plans that prescribe more generics than 
average or would otherwise contribute to adverse selection incentives.
    Several other commenters noted a preference for generic drugs to be 
included in the definition of the PrEP ACF on the basis that excluding 
generics may incentivize prescription of brand name drugs and 
inefficient care patterns. A few of these commenters noted that issuers 
are likely receiving considerable manufacturer rebates for PrEP that 
may not be reflected in the enrollee-level EDGE data that HHS uses for 
risk adjustment model recalibration.
    One commenter who supported the exclusion of generics requested 
that step-therapy requirements be instituted for PrEP drugs that have 
both a generic and brand name formulation. A few commenters noted an 
interest in splitting the PrEP ACF into two ACFs according to brand 
name/generic status or based on oral/injectable form.
    Response: We appreciate the comments and agree with the position 
that the vast difference in costs between brand name and generic PrEP 
drugs warrants an exclusion for generic drugs from the definition of 
the PrEP ACF. Although excluding generic drugs from the definition of a 
model factor may, in many cases, encourage the prescription of brand 
name drugs over generic drugs and encourage inefficient care patterns, 
we do not believe this is especially likely in the case of PrEP due to 
the very large difference in price between the only generic form of 
PrEP available on the market and the multiple brand name forms 
available. Moreover, we are concerned that the inclusion of generic 
drugs would lead to an overpayment for coverage of generic drugs and an 
underpayment for coverage of brand name drugs, potentially 
incentivizing issuers to limit access to brand name drugs. Because 
there is presently only one form of generic PrEP available on the 
market (a daily oral regimen), barriers to accessing brand name drugs, 
including step-therapy requirements, would only limit access to newer 
and more tolerable formulations, including long-acting injectable forms 
of PrEP. Additionally, step-therapy requirements would be inconsistent 
with recently released guidance relating to coverage of preventive 
services under section 2713 of the PHS Act specifying that issuers must 
cover, without cost sharing, all three FDA-approved PrEP formulations 
(two oral and one injectable) and are not permitted to use medical 
management techniques to direct individuals prescribed PrEP to utilize 
one formulation over another.\78\ As such, to further limit the 
influence of perverse incentives, to align with the recent guidance, 
and in recognition of the very large difference in price between 
generic and brand name forms of PrEP, beginning with the 2026 benefit 
year, we are finalizing the addition of the PrEP ACF to the HHS risk 
adjustment adult and child models with an exclusion of generic versions 
of PrEP medication from the definition of the PrEP ACF. We will 
continue to monitor the impact of the new PrEP ACF, as well as the cost 
and utilization of PrEP drugs in the market, and may consider 
alterations to the new PrEP ACF if the prices of generic and brand name 
forms of PrEP become more comparable, additional generic forms of PrEP 
enter the market, or we observe market distortions or other impacts 
resulting from the addition of the new PrEP ACF to the adult and child 
models that should be addressed.

    \78\ See <a href="https://www.cms.gov/files/document/faqs-implementation-part-68.pdf">https://www.cms.gov/files/document/faqs-implementation-part-68.pdf</a>.
---------------------------------------------------------------------------

    We may also consider the potential addition of a separate generic 
drug PrEP ACF in the future, but would need to consider whether the 
inclusion of an ACF for generic drugs would satisfy the principles 
finalized in this rule to guide the adoption of potential additional 
ACFs in the future. In particular, we would need to consider whether a 
generic drug PrEP ACF would satisfy the principle of meaningful and 
predictable costs (Principle 2), as the cost of the generic version of 
PrEP currently available on the market is fairly low and may not 
produce a meaningful coefficient if incorporated into the HHS risk 
adjustment adult and child models. As part of this future analysis, we 
may also consider whether a distinction between oral and injectable 
PrEP is warranted. However, we note that the annual costs of brand name 
oral and injectable forms are currently similar and that the only 
generic form of PrEP currently available is an oral form. Therefore, 
the splitting of the PrEP ACF into oral and injectable forms may still 
necessitate the exclusion of generic PrEP due to the cost disparity 
between the generic and brand name oral forms, which would continue to 
lead to overprediction for the generic form, incentivizing issuers to 
use medical management techniques to direct individuals prescribed oral 
PrEP to utilize the generic oral formulation over other branded oral 
forms that may have fewer side effects or otherwise be more appropriate 
for the enrollee. We would seek input from interested parties through 
notice-and-comment rulemaking or other appropriate vehicles on any such 
potential changes.
    Regarding the comments related to manufacturer rebates, we 
acknowledge that manufacturer rebates are common and may impact drug 
prices for a wide variety of prescription drugs.\79\ We note that 
issuers are currently instructed that they do not need to adjust the 
reported Plan Paid Amount to reflect manufacturer rebates in the data 
made available to HHS through issuers' EDGE servers.\80\ As such, using 
enrollee-level EDGE data to precisely account for manufacturer rebates 
for any prescription drugs in the HHS risk adjustment adult and child 
models may necessitate changes to issuers' data submission practices. 
We continue to consider these issues and different ways to potentially 
account for these rebates in the HHS risk adjustment models in future 
benefit years.

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

    Comment: All commenters on the two hierarchy options set forth in 
the proposed rule preferred the alternative approach in which HHS would 
allow adult enrollees with HIV to receive credit for PrEP and place the 
PrEP ACF in the adult models in a hierarchy below RXC 1 (Anti-HIV 
Agents). Commenters noted that this approach is the most 
straightforward approach, that it maintains a strong adherence to the 
seven principles for developing a new ACF factor set forth in the 
proposed rule, and that it ensures that the HHS risk adjustment models 
can distinguish between preventive use of PrEP and treatment of active 
HIV infection, thus mitigating overlap issues and preserving the 
integrity of the classification system.

[[Page 4444]]

    One commenter suggested that if the ACF for PrEP is added to the 
HHS risk adjustment child models, RXC 1 (Anti-HIV Agents) should also 
be added to the child models with the same hierarchy specifications as 
the adult models. This commenter asserted that without this 
modification, it may be difficult to differentiate enrollees subject to 
the child models who are on PrEP from those who are taking 
antiretrovirals to manage active HIV infections.
    Response: We agree that the alternative hierarchy approach for the 
adult models set forth in the proposed rule is straightforward and 
would appropriately address the hierarchy concerns identified in the 
proposed rule with regards to the adult models, namely the violations 
of the hierarchical factor definitions principle (Principle 4), the 
monotonicity principle (Principle 5), and the mutually exclusive 
classification system principle (Principle 6).\81\ Because we are able 
to appropriately address these violations through the adoption of the 
alternative hierarchy approach, we also agree that the adult models 
will be able to appropriately distinguish between the preventive use of 
PrEP and the treatment of an active HIV infection. Therefore, in the 
HHS risk adjustment adult models we are finalizing the hierarchy option 
that places the PrEP ACF below RXC 1 in a hierarchy without defining 
any hierarchical relationship between the PrEP ACF and HCC 1 (HIV/
AIDS). Under this approach, adult enrollees without RXC 1 will 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. Further, under this approach, an adult enrollee 
with a PrEP prescription claim in their medical records for the benefit 
year who later tests positive for HIV in the same benefit year would 
have an increase in their risk score for that year as a result of the 
additional diagnosis, appropriately satisfying the principles of 
additivity (Principle 4) and monotonicity (Principle 5).
---------------------------------------------------------------------------

    \81\ This alternative hierarchy approach satisfies 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.
---------------------------------------------------------------------------

    Regarding the comment requesting the addition of RXC 1 to the child 
models with the same hierarchy specifications as the adult models, we 
did not propose and are not finalizing the addition of any RXCs to the 
HHS risk adjustment child models. Currently, only the HHS risk 
adjustment adult models include RXCs. Determining whether it is 
appropriate to add any RXCs to the child models would require careful 
analysis and consideration, and we would want to solicit public comment 
on such analysis, which was not possible between the receipt of these 
comments and publication of this final rule. For example, similar to 
the development of the RXC-HCC pairs for the HHS risk adjustment adult 
models, we would need to work with clinicians to analyze, select, and 
tailor the RXCs that could be used to impute diagnoses and to indicate 
the severity of diagnoses otherwise indicated through medical coding as 
appropriate for the child models.\82\ We would also need to propose and 
solicit comments on such potential draft factors in the applicable HHS 
notice of benefit and payment parameters.
---------------------------------------------------------------------------

    \82\ For information on the development of the RXC-HCC pairs for 
the adult models, including the guiding principles and other 
considerations, see the 2018 Payment Notice Proposed Rule (81 FR 
61456, 61470-71), the 2018 Payment Notice Final Rule (81 FR 94058, 
94075-80), and the 2019 Payment Notice Final Rule (83 FR 16930, 
16941-43). Also see Chapter 4, 2016 HHS Risk Adjustment White Paper, 
available at: <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>.
---------------------------------------------------------------------------

    However, we agree with the commenter that there is an important 
issue with the hierarchy specification(s) related to the addition of 
the PrEP ACF in the child models that needs to be addressed when 
finalizing these new factors for the models. To explain, we first note 
that because the HHS risk adjustment child models do not contain RXCs, 
the costs of HIV treatment (inclusive of the HIV treatment medication 
regimens captured in RXC 1 in the adult models) are accounted for in 
the HCC 1 coefficient in the child models. As such, in contrast to the 
adult models, where the RXC 1 coefficient is generally larger than the 
PrEP ACF or HCC 1 coefficient, with the HCC 1 coefficient having the 
smallest coefficient of the three adult model factors, the absence of 
RXC 1 in the child models generally results in a higher coefficient for 
HCC 1 than the PrEP ACF coefficient. As such, without a hierarchy 
specification limiting the application of the PrEP ACF in the child 
models, an enrollee subject to the child models who was on PrEP for 
part of a benefit year, but was later diagnosed with HIV (and would 
therefore likely be prescribed treatment for an active HIV infection 
instead) would receive a large increase to their risk score 
(approximately 3.993, per the draft silver coefficient for HCC 1 in the 
child models as reflected in Table 5 of the proposed rule) \83\ because 
the enrollee would be receiving risk score components associated with 
both prevention and treatment of HIV. However, in the context of the 
adult model PrEP ACF and hierarchy specification finalized in this 
rule, a similar enrollee subject to the adult models who was on PrEP 
for part of a benefit year, but was later diagnosed with HIV and 
started to take an RXC 1 drug for treatment would receive a much 
smaller increase to their risk score (approximately 1.962 per the 
silver coefficients for the adult models as reflected in Tables 2 and 4 
of the proposed rule) \84\ because the enrollee's risk score would only 
reflect the difference in cost associated with treatment relative to 
prevention.
---------------------------------------------------------------------------

    \83\ See 89 FR 82308, 82328-41. Note that these values are 
approximate and presented here only for illustrative purposes. We 
note that the proposed rule estimates included generic drugs in the 
definition of the PrEP ACF but in this rule we are finalizing that 
generic drugs will be excluded from PrEP ACF definition for both the 
adult and child models. As such, these values should be taken only 
as rough estimates of the impact of the hierarchy specification on 
the example enrollee.
    \84\ Ibid.
---------------------------------------------------------------------------

    Pending further research and consideration on the impact of adding 
RXCs (such as RXC 1) to the child models, to better align the 
representation of risk between the adult and child models and more 
appropriately reflect the cost of enrollees who receive both PrEP and 
HIV treatment in the same benefit year in the child models, we believe 
that an appropriate approach would be to place the PrEP ACF below HCC 1 
in a hierarchy in the child models. This would allow the risk score of 
an enrollee subject to the child models who was on PrEP for part of a 
benefit year but was later diagnosed with HIV to reflect only the 
difference in cost associated with treatment relative to prevention 
(approximately 2.719 per the silver coefficients for the child models 
as reflected in Tables 3 and 5 of the proposed rule) \85\ rather than 
the whole cost of both treatment and prevention.
---------------------------------------------------------------------------

    \85\ Ibid.
---------------------------------------------------------------------------

    We are finalizing as proposed the addition of a new PrEP ACF to the 
child models and, in response to comments, we will place the PrEP ACF 
in a hierarchy below HCC 1 in the child models to ensure that child 
enrollees who have both a PrEP prescription claim and an HCC 1 (HIV/
AIDS) diagnosis reflected in their medical records for a benefit year 
(and are therefore likely receiving active treatment) will receive an 
appropriate increase to their risk score relative to enrollees in the 
child models without an

[[Page 4445]]

HCC 1 diagnosis who have a PrEP prescription claim in their medical 
records for that year.
    We will consider if any additional changes to the child models are 
necessary as we continue to monitor the impact of the new PrEP ACF and 
consider potential refinements to the ACF framework in future benefit 
years. As always, as part of our ongoing efforts to continually improve 
the precision of the HHS risk adjustment models, we will seek input 
from interested parties through notice-and-comment rulemaking or other 
appropriate vehicles on potential changes to the models in future 
benefit years.
    Comment: Several commenters offered ideas for additional ACFs to be 
added to the HHS risk adjustment models in the future. These included 
ACFs for biologic drugs, GLP-1 drugs, and cellular and gene therapies. 
Other commenters' suggestions requested the use of the ACF framework to 
restructure how childbirth, organ transplants, end stage renal disease 
(ESRD), dialysis, respirator dependance, amputations, autism spectrum 
disorder, moderate forms of psychiatric illness, and prophylactic 
interventions such as prophylactic mastectomy are accounted for in the 
HHS-operated risk adjustment program.
    A few commenters requested changes to the risk adjustment 
specifications for one or more of these conditions without specifying 
that the ACF framework was the proper vehicle for addressing their 
concerns.
    Response: We did not propose and therefore are not finalizing the 
adoption of additional ACFs at this time. However, we are finalizing 
the adoption of the ACF framework and the proposed principles to guide 
any potential development of additional ACFs to the HHS risk adjustment 
models in the future. We appreciate the suggestions regarding other 
conditions or diagnoses for which it may be appropriate to leverage the 
ACF framework to restructure or refine the treatment of the other 
identified clinically meaningful enrollee characteristics in the HHS 
risk adjustment models. As we consider potential refinements to the ACF 
structure and other changes to the HHS risk adjustment models in the 
future, we may further consider these suggestions and the structure of 
related HCCs. As always, as part of our ongoing efforts to continually 
improve the precision of the HHS risk adjustment models, if we were to 
make changes to the ACF structure or other changes to the HHS risk 
adjustment models in the future, we will seek input from interested 
parties through notice-and-comment rulemaking or other appropriate 
vehicles on such potential changes.
    After consideration of comments and for the reasons outlined in the 
proposed rule and this final rule, including our responses to comments 
above, we are finalizing the addition of PrEP as an ACF in the adult 
and child risk adjustment models beginning with the 2026 benefit year. 
Furthermore, we are finalizing the exclusion of generic versions of 
PrEP from the PrEP ACF and are finalizing the placement of the PrEP ACF 
in the adult models in a hierarchy below RXC 1 (Anti-HIV Agents) 
without defining any hierarchical relationship between the PrEP ACF and 
HCC 1 (HIV/AIDS). In the child models, which do not contain RXCs, we 
are finalizing the placement of the PrEP ACF in a hierarchy below HCC 
1. Additionally, we are finalizing the proposed ACF framework and 
principles used to determine whether it is appropriate to add a new ACF 
to the HHS risk adjustment models, and how the hierarchy structure 
associated with an ACF should be defined.
    We were unable to complete the calculations for the final 
coefficients in time to publish them in this final rule because 
additional time is needed to complete the calculations needed to 
account for the incorporation of the PrEP ACF with the generic drug 
exclusions and hierarchy specifications finalized in this rule. 
Therefore, consistent with Sec.  153.320(b)(1)(i), we will publish the 
final coefficients for the 2026 benefit year in guidance after the 
publication of this final rule. We will release this guidance by the 
spring of 2025 in time for rate setting for the 2026 benefit year.
d. List of Factors To Be Employed in the HHS Risk Adjustment Models 
(Sec.  153.320)
    Consistent with Sec.  153.320(b)(1)(i), we are finalizing the use 
of the 2020, 2021 and 2022 enrollee-level EDGE data to calculate the 
2026 benefit year coefficients and will publish the final coefficients 
for the 2026 benefit year in guidance after the publication of this 
final rule, as we were unable to complete the calculations to finalize 
them in time to publish them in this final rule,\86\ due to the 
additional calculations needed to account for the incorporation of the 
PrEP ACF with the generic drug exclusions and hierarchy specifications 
as finalized in this rule. The proposed 2026 benefit year HHS risk 
adjustment model factors resulting from the equally weighted (averaged) 
blended factors from separately solved models using 2020, 2021, and 
2022 enrollee-level data are shown in Tables 2 through 9 of the HHS 
Notice of Benefit and Payment Parameters for 2026 proposed rule (89 FR 
82308, 82328 through 46). As we have done for certain prior benefit 
years,\87\ we will release the final 2026 benefit year coefficients in 
guidance after publication of this final rule by the spring of 2025 in 
time for rate setting for the 2026 benefit year. We received several 
comments requesting additional changes to the HHS risk adjustment 
models that we did not consider or propose in the proposed rule. We 
respond to these comments below.

    Comment: One commenter suggested that HHS update the risk 
adjustment models to incorporate Tepezza and Graves Disease/
Hyperthyroidism.
    Response: We did not propose and are not finalizing changes to add 
an RXC to the HHS risk adjustment adult models for Tepezza, which 
treats thyroid eye disease, or to add a payment HCC for Graves Disease/
Hyperthyroidism. We recently discussed the approach to the treatment of 
Tepezza and Graves Disease/Hyperthyroidism in the HHS risk adjustment 
models in the 2025 Payment Notice final rule,\88\ explaining that 
thyroid eye disease (thyrotoxicosis) is currently categorized in a 
condition category (Other Endocrine/Metabolic/Nutritional Disorders) 
that is not a payment HCC in the HHS risk adjustment models. Further, 
all RXCs in the HHS adult risk adjustment models are associated with a 
payment HCC. We therefore generally have concerns about adding thyroid 
eye disease to the HHS risk adjustment models at this time as it is 
currently not categorized as a payment HCC and we would need to perform 
further analysis to consider whether it is appropriate and how best

[[Page 4446]]

to incorporate this condition into the models given these concerns. For 
these reasons, HHS did not propose and is not finalizing any changes 
with respect to the treatment of Tepezza for thyroid eye disease in the 
2026 benefit year risk adjustment models. However, HHS intends to 
continue analysis of Graves Disease/Hyperthyroidism and thyrotoxicosis 
and the use of Tepezza as more data becomes available and consider 
potential changes to the treatment of this condition and drug in the 
HHS risk adjustment models for future benefit years.

    Comment: A few commenters identified certain conditions that they 
believe are undercompensated in the risk adjustment models. These 
conditions included autism spectrum disorder, ESRD, and maternal and 
newborn care. These commenters requested that HHS reconsider how these 
conditions and their associated costs are accounted for in the HHS risk 
adjustment models. Additionally, one commenter requested that HHS 
revisit the analysis in the 2021 RA Technical Paper,\89\ expressing 
concern that the risk associated with the lowest-risk enrollees remains 
underpredicted by the HHS risk adjustment models. One commenter 
recommended that HHS study the impact of calibrating the HHS risk 
adjustment models separately for the individual and small group markets 
due to differences in the characteristics of the enrollee population 
between the two markets. Furthermore, one commenter recommended that 
HHS consider ways to account for plan design generosity as more 
generous plans tend to attract enrollees with expensive chronic 
conditions.

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

    Response: We appreciate the suggestions regarding conditions that 
commenters identified for review of how they are accounted for in the 
HHS risk adjustment models. Although we did not propose and are not 
finalizing changes to the treatment of the identified conditions in the 
2026 benefit year risk adjustment models, we generally note that we 
consistently monitor the performance of the risk adjustment models, 
including through out-of-sample analysis of predictive ratios 
associated with each model factor, as additional years of enrollee-
level EDGE data become available. Results of these monitoring 
activities were a key impetus for several risk adjustment model changes 
finalized in the 2023 Payment Notice \90\ to address the adult and 
child models' underprediction for enrollees with many HCCs. 
Specifically, we finalized the interacted HCC counts and HCC-contingent 
enrollment duration factor model specifications to improve model 
prediction for higher risk enrollees and ensure that issuers are being 
accurately compensated for these enrollees. As such, the potential for 
underprediction or overprediction in the HHS risk adjustment models is 
an area that HHS is consistently monitoring and addressing as needed 
and will continue to monitor and address in the future as part of our 
ongoing efforts to continually improve the HHS risk adjustment models. 
We also note that the conditions or diagnoses identified in these 
comments show strong overlap with the conditions that some commenters 
identified as being appropriate to be addressed by the ACF framework 
and that, as stated in our response to comments about those conditions 
in that section of this final rule, we will take these comments into 
consideration as we consider potential refinements to the HHS risk 
adjustment models in future benefit years.

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

    In regard to the request to revisit the analysis in the 2021 RA 
Technical Paper, we appreciate the commenter's concern. As noted in the 
2023 Payment Notice,\91\ our analysis of the addition of the interacted 
HCC counts factors in the adult and child models, the removal of the 
former adult model severity illness factors, and the replacement of the 
former enrollment duration factors with the HCC-contingent enrollment 
duration factors in the adult models found that the combined impact of 
these changes would significantly improve predictions across most 
deciles and HCC counts for the very highest-risk enrollees, as well as 
the lowest-risk enrollees without HCCs.\92\ These model specification 
updates were implemented starting with the 2023 benefit year HHS risk 
adjustment models and we intend to monitor the impact of these updates 
as part of future benefit years' model recalibrations using additional 
years of available enrollee-level EDGE data.

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

    As we consider potential refinements to the HHS risk adjustment 
models in the future, we will also continue to monitor the specific 
conditions identified by commenters, along with the structure of 
related model factors, and the impact of recent model specification 
updates on the ability of the models to predict risk across all 
subgroups of enrollees and enrollees with chronic conditions who are 
more likely to enroll in plans with more generous coverage. We also 
will continue to study whether differences in the characteristics of 
the enrollee population between the individual and small groups markets 
would warrant calibrating the HHS risk adjustment models separately for 
the individual and small group markets. As always, as part of our 
ongoing efforts to continually improve the precision of the HHS risk 
adjustment models, if we were to pursue changes to the risk adjustment 
models in the future, we will seek input from interested parties 
through notice-and-comment rulemaking or other appropriate vehicles.
    Comment: Several commenters requested clarification regarding how 
medically administered injectable drugs are accounted for in the HHS 
risk adjustment models. These commenters were concerned that these 
drugs appear to be filtered out of enrollee claims data for the purpose 
of calculating risk scores.
    Response: We appreciate commenters bringing this concern to our 
attention. Although not expressly stated by commenters, we believe 
these concerns stem from the commenters' interpretation of language in 
guidance document(s) such as the Risk Adjustment DIY Software 
Instructions.\93\ To clarify, for RXC eligibility (including medically 
administered injectable claims), a professional or outpatient medical 
claim does not need to have a risk adjustment eligible service code or 
bill type code. Instead, the professional or outpatient claim simply 
needs to have a service code that maps to an RXC for selection and 
inclusion in enrollee claims data for purposes of calculating risk 
scores. We intend to update language in these guidance document(s) in 
future releases to clarify this point.

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

[[Page 4447]]

adjustment factors for silver plan variant enrollees (70 percent, 73 
percent, 87 percent, and 94 percent AV plan variants) \94\ for the 2025 
benefit year and beyond, unless changed through notice-and-comment 
rulemaking.
---------------------------------------------------------------------------

25772-74; and 89 FR 26218, 26252-54.
---------------------------------------------------------------------------

    For the 2026 benefit year, we did not propose to change the CSR 
adjustment factors as finalized in the 2025 Payment Notice and we will 
maintain the existing CSR adjustment factors for the 2026 benefit 
year.\95\ We summarize and respond to the public comments received on 
the CSR adjustment factors for the 2026 benefit year below.
---------------------------------------------------------------------------

    \95\ See CSR adjustment factors finalized in the 2025 Payment 
Notice at 89 FR 26252 through 26254.
---------------------------------------------------------------------------

    Comment: We received a few comments asking that HHS revisit the CSR 
factors for Massachusetts wraparound plans, specifically for wrap-
around plans with AVs above 94 percent. These commenters stated that 
the wrap-around plans with AVs above 94 percent warrant higher CSR 
factors than the current 1.12 values. One of these commenters compared 
the current CSR factor used for Massachusetts wrap-around plans with 
AVs above 94 percent to those used in Arkansas for plans the commenter 
identified as having similar AVs.
    Response: For all plan liability risk score calculations under the 
State payment transfer formula, we use the CSR adjustment factor that 
aligns with the AV of the applicable plan for the enrollee. Thus, for 
unique State-specific plans, we apply the CSR adjustment factors that 
correspond to each plan's AV. As we identify unique State-specific 
plans that have higher plan liability than the standard plan variants, 
such as those in Massachusetts and Arkansas, we work with the relevant 
State Departments of Insurance and other relevant State agencies to 
identify the applicable CSR adjustment factor that corresponds to the 
unique State-specific plan's AV.
    Regarding the comparison between Massachusetts' wrap-around plans 
and Arkansas' Medicaid expansion plans, Arkansas Medicaid expansion 
plans are identical to other 94 percent and 100 percent AV CSR plan 
variants offered on the Exchange and are distinguished from these 
identical plans only in their sources of funding and eligibility 
criteria. As such, we presently direct issuers in Arkansas who provide 
Medicaid expansion plans with AVs of 94 percent and 100 percent to use 
specified plan variant codes for their Medicaid expansion plans only to 
differentiate the sources of funding and to differentiate between 
populations eligible for the Medicaid expansion plans from those who 
are eligible for standard 94 percent and 100 percent AV CSR plan 
variants. In contrast, in Massachusetts, the higher cost sharing wrap-
around plans are variations of lower cost sharing plans and do not have 
the same AVs as their comparable plans.
    We will continue to follow this approach, working with the State to 
identify the applicable CSR adjustment factor that corresponds to that 
State's unique State-specific plan's AV. As of the release of this 
final rule, the Massachusetts Division of Insurance, which is the 
regulating body for the State, has not identified changes to the AVs of 
the State's wrap-around plans. As such, we are maintaining our general 
approach to determining the CSR factors for State-specific plans, 
including Massachusetts wrap-around plans, for the 2026 benefit year.
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 noted 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.\96\ Because we are 
finalizing a blend the coefficients from separately solved models based 
on the 2020, 2021 and 2022 benefit years' enrollee-level EDGE data, we 
publish the R-squared statistic for each model separately to verify 
their statistical validity. We will include the R-squared statistics 
for the final 2026 benefit year models when we publish the final 
coefficients for the 2026 benefit year in guidance after publication of 
this final rule. We will release this guidance by the spring of 2025, 
in time for rate setting for the 2026 benefit year.

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 
did not propose any changes to the formula in the proposed rule, and 
therefore, did not republish the formulas in the proposed rule. We 
therefore will 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 did not propose any 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.\97\
