Abstract

This document sets forth final rules amending regulations implementing the Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) and adding new regulations implementing the nonquantitative treatment limitation (NQTL) comparative analyses requirements under MHPAEA, as amended by the Consolidated Appropriations Act, 2021 (CAA, 2021). Specifically, these final rules amend the existing NQTL standard to prohibit group health plans and health insurance issuers offering group or individual health insurance coverage from using NQTLs that place greater restrictions on access to mental health and substance use disorder benefits as compared to medical/surgical benefits. As part of these changes, these final rules require plans and issuers to collect and evaluate relevant data in a manner reasonably designed to assess the impact of NQTLs on relevant outcomes related to access to mental health and substance use disorder benefits and medical/surgical benefits and to take reasonable action, as necessary, to address material differences in access to mental health or substance use disorder benefits as compared to medical/surgical benefits. These final rules also amend existing examples and add new examples on the application of the rules for NQTLs to clarify and illustrate the requirements of MHPAEA. Additionally, these final rules set forth the content requirements for NQTL comparative analyses and specify how plans and issuers must make these comparative analyses available to the Department of the Treasury (Treasury), the Department of Labor (DOL), and the Department of Health and Human Services (HHS) (collectively, the Departments), as well as to an applicable State authority, and to participants, beneficiaries, and enrollees. Finally, HHS finalizes regulatory amendments to implement the sunset provision for self-funded non-Federal governmental plan elections to opt out of compliance with MHPAEA, as adopted in the Consolidated Appropriations Act, 2023 (CAA, 2023).

SUMMARY: This document sets forth final rules amending regulations 
implementing the Paul Wellstone and Pete Domenici Mental Health Parity 
and Addiction Equity Act of 2008 (MHPAEA) and adding new regulations 
implementing the nonquantitative treatment limitation (NQTL) 
comparative analyses requirements under MHPAEA, as amended by the 
Consolidated Appropriations Act, 2021 (CAA, 2021). Specifically, these 
final rules amend the existing NQTL standard to prohibit group health 
plans and health insurance issuers offering group or individual health 
insurance coverage from using NQTLs that place greater restrictions on 
access to mental health and substance use disorder benefits as compared 
to medical/surgical benefits. As part of these changes, these final 
rules require plans and issuers to collect and evaluate relevant data 
in a manner reasonably designed to assess the impact of NQTLs on 
relevant outcomes related to access to mental health and substance use 
disorder benefits and medical/surgical benefits and to take reasonable 
action, as necessary, to address material differences in access to 
mental health or substance use disorder benefits as compared to 
medical/surgical benefits. These final rules also amend existing 
examples and add new examples on the application of the rules for NQTLs 
to clarify and illustrate the requirements of MHPAEA. Additionally, 
these final rules set forth the content requirements for NQTL 
comparative analyses and specify how plans and issuers must make these 
comparative analyses available to the Department of the Treasury 
(Treasury), the Department of Labor (DOL), and the Department of Health 
and Human Services (HHS) (collectively, the Departments), as well as to 
an applicable State authority, and to participants, beneficiaries, and 
enrollees. Finally, HHS finalizes regulatory amendments to implement 
the sunset provision for self-funded non-Federal governmental plan 
elections to opt out of compliance with MHPAEA, as adopted in the 
Consolidated Appropriations Act, 2023 (CAA, 2023).

DATES: 
    Effective date: These regulations are effective on November 22, 
2024.
    Applicability date: See the SUPPLEMENTARY INFORMATION section for 
information on the applicability dates.

SUPPLEMENTARY INFORMATION:

I. Background

    America continues to experience a mental health and substance use 
disorder crisis affecting people across all demographics, with 
marginalized communities disproportionately impacted.\1\ The COVID-19 
pandemic exacerbated the crisis, but its effects have continued post-
pandemic.\2\ From August 19, 2020, to February 1, 2021, the percentage 
of adults exhibiting symptoms of an anxiety or a depressive disorder 
rose from 36.4 percent to 41.5 percent.\3\ In 2022, there were an 
estimated 15.4 million adults aged 18 or older in the United States 
with a serious mental illness and nearly one in four adults (59.3 
million) living with any mental illness.\4\

    Additionally, in 2022, nearly 54.6 million people aged 12 or older 
were classified as needing treatment for substance use, but only about 
24 percent of those people received any treatment, according to the 
Substance Abuse and Mental Health Services Administration's (SAMHSA) 
National Survey on Drug Use and Health (NSDUH).\5\ The unmet need for 
treatment for substance use disorders has been even greater among 
racial minorities and other marginalized communities. Between 2019 and 
2021, median monthly overdose deaths among persons aged 10-19 years 
increased 109 percent; and deaths involving illicitly manufactured 
fentanyl increased 182 percent.\6\ In 2021, American Indian and Alaskan 
Native men aged 15-34 had an age-adjusted death rate caused by drug 
overdoses of 42 per 100,000 people, compared to 20.5 age-adjusted 
deaths per 100,000 people during the same time period in 2018.\7\ Non-
Hispanic Black or African American men aged 35-64 had an age-adjusted 
death rate caused by drug overdoses of 61.2 per 100,000 people; an 
increase from 30.6 deaths per 100,000 people during the same time 
period in 2018.\8\

    Following the COVID-19 pandemic, employers highlighted that they 
have responded to the impact of the pandemic on the mental health and 
substance use disorder crisis by offering more comprehensive benefits, 
including

[[Page 77587]]

mental health support. According to a report published in 2021, ``about 
three in four large employers and two in four small/medium employers 
report that they offer at least one type of mental health support for 
employees.'' \9\ In a recent survey, 87 percent of large employers 
stated that access to mental health care was a top priority, and 
another survey found that ``the number of in-network behavioral health 
providers has increased by an average of 48 percent in 3 years among 
commercial health plans.'' \10\ Group health plans and health insurance 
issuers have taken steps to ensure mental health parity is reflected in 
their benefit designs and to educate participants, beneficiaries, and 
enrollees \11\ about MHPAEA's requirements, by reaching out to members, 
expanding telehealth availability, expanding behavioral health provider 
networks, integrating behavioral health with physical health care, and 
working to reduce stigmatization of seeking treatment.

    \11\ Consistent with the proposed rules, these final rules apply 
directly to group health plans or health insurance coverage offered 
by an issuer in connection with a group health plan, and apply to 
individual health insurance coverage by cross-reference through 45 
CFR 147.160, which currently provides that the requirements of 45 
CFR 146.136 apply to health insurance coverage offered by a health 
insurance issuer in the individual market in the same manner and to 
the same extent as to health insurance coverage offered by a health 
insurance issuer in connection with a group health plan in the large 
group market. As noted later in this preamble, HHS is finalizing an 
amendment to 45 CFR 147.160 to also include a cross-reference to 45 
CFR 146.137 to similarly extend the new comparative analysis 
requirements to individual health insurance coverage in the same 
manner and to the same extent as group health insurance coverage. 
For simplicity, this preamble generally refers only to the 
applicability to group health plans and health insurance coverage 
offered in connection with a group health plan and to participants 
and beneficiaries enrolled in such a plan or coverage, but 
references to participants and beneficiaries should also be 
considered to include enrollees in the individual market, unless 
otherwise specified.
---------------------------------------------------------------------------

    Despite these efforts, disparities in coverage between mental 
health and substance use disorder benefits and medical/surgical 
benefits have grown. In the preamble to the proposed rules,\12\ the 
Departments cited a 2019 Milliman report \13\ that found a growing 
disparity in the utilization of out-of-network behavioral health care 
providers relative to out-of-network medical/surgical care providers. A 
recent study by RTI International \14\ found that out-of-network use 
was 3.5 times higher for all behavioral health clinician office visits 
than for all out-of-network medical/surgical clinician office visits; 
in addition, the study noted that these disparities in out-of-network 
use for behavioral health office visits compared to medical/surgical 
office visits have remained large and, according to the study, are not 
fully attributable to behavioral health provider shortages. The study 
concluded that these results demonstrate the need for more robust 
parity enforcement.

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

    RTI concluded that its analyses of the most recent, comprehensive 
private insurance claims data

reveal material differences in access to mental health and substance 
use disorder benefits as compared to medical/surgical benefits, as 
reflected in much greater use of out-of-network providers. . . . 
These disparities indicate that behavioral health networks are 
clearly inadequate and signal potential noncompliance with the NQTL 
requirements of MHPAEA.\15\
---------------------------------------------------------------------------

    \15\ Id. at 46.

    These final rules aim to strengthen consumer protections consistent 
with MHPAEA's fundamental purpose--to ensure that individuals in group 
health plans or with group or individual health insurance coverage who 
seek treatment for covered mental health conditions or substance use 
disorders do not face greater burdens on access to benefits for those 
conditions or disorders than they would face when seeking coverage for 
the treatment of a medical condition or a surgical procedure.\16\ As 
highlighted in the preamble to the proposed rules,\17\ such barriers 
are particularly problematic when the benefits that the plan or issuer 
purports to make available and that individuals reasonably expect to be 
covered are not in fact covered. To the extent these barriers 
disproportionately limit access to mental health or substance use 
disorder benefits, such practices contravene MHPAEA's statutory 
language, which requires that the financial requirements and treatment 
limitations applicable to mental health or substance use disorder 
benefits be ``no more restrictive'' than the predominant requirements 
and limitations applicable to substantially all medical/surgical 
benefits.\18\ The Departments' enforcement efforts have shown that such 
barriers persist more than 15 years after MHPAEA's enactment.\19\ These 
final rules are critical to addressing barriers to access to mental 
health and substance use disorder benefits.
---------------------------------------------------------------------------

    \16\ In a floor statement, Representative Patrick Kennedy (D-
RI), one of the chief architects of MHPAEA, made the case for its 
passage on the grounds that ``access to mental health services is 
one of the most important and most neglected civil rights issues 
facing the Nation. For too long, persons living with mental 
disorders have suffered from discriminatory treatment at all levels 
of society.'' 153 Cong. Rec. S1864-5 (daily ed. Feb. 12, 2007). Cf. 
H. Rept. 110-374, part 3 (Mar. 4, 2008), <a href="https://www.congress.gov/congressional-report/110th-congress/house-report/374">https://www.congress.gov/congressional-report/110th-congress/house-report/374</a> (``The purpose 
of H.R. 1424, the `Paul Wellstone Mental Health and Addiction Equity 
Act of 2007' is to have fairness and equity in the coverage of 
mental health and substance-related disorders vis-a-vis coverage for 
medical and surgical disorders.'').

Employee Retirement Income Security Act of 1974 (ERISA) section

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

    The problems persist notwithstanding the Departments' unprecedented 
commitment to advance parity for mental health and substance use 
disorder benefits in recent years, as reflected through increased 
enforcement efforts and the Departments' work with interested parties 
to help them understand and comply with MHPAEA's requirements.\20\ To 
promote compliance, the Departments have provided extensive guidance 
and compliance assistance materials, especially with respect to 
NQTLs,\21\ yet disparities still persist.
---------------------------------------------------------------------------

    \20\ More information on the Departments' enforcement efforts 
and guidance issued under MHPAEA is available at <a href="https://www.dol.gov/agencies/ebsa/laws-and-regulations/laws/mental-health-and-substance-use-disorder-parity/tools-and-resources">https://www.dol.gov/agencies/ebsa/laws-and-regulations/laws/mental-health-and-substance-use-disorder-parity/tools-and-resources</a> and <a href="https://www.cms.gov/marketplace/private-health-insurance/mental-health-parity-addiction-equity">https://www.cms.gov/marketplace/private-health-insurance/mental-health-parity-addiction-equity</a>.
    \21\ As discussed in more detail later in this preamble, NQTLs 
are generally non-numerical limits on the scope or duration of 
treatment, such as prior authorization requirements, step therapy, 
and standards related to network composition.
---------------------------------------------------------------------------

    In 1996, Congress enacted the Mental Health Parity Act of 1996 
(MHPA 1996), which required parity in aggregate

[[Page 77588]]

lifetime and annual dollar limits for mental health benefits and 
medical/surgical benefits for group health plans and health insurance 
coverage offered in connection with such plans.\22\ These mental health 
parity provisions were codified in Code section 9812, ERISA section 
712, and PHS Act section 2705.\23\ Congress expanded on these efforts 
in 2008 with the enactment of MHPAEA,\24\ which amended Code section 
9812, ERISA section 712, and PHS Act section 2705 by adding 
requirements for plans and issuers related to financial requirements 
and treatment limitations and made further amendments to the existing 
mental health parity provisions, including provisions to apply the 
mental health parity requirements to substance use disorder benefits.
---------------------------------------------------------------------------

    \22\ Public Law 104-204, 110 Stat. 2874 (Sept. 26, 1996). The 
Departments published interim final rules implementing MHPA 1996 at 
62 FR 66932 (Dec. 22, 1997).
    \23\ The Departments published interim final rules implementing 
MHPA 1996 at 62 FR 66932 (Dec. 22, 1997).
    \24\ Sections 511 and 512 of the Tax Extenders and Alternative 
Minimum Tax Relief Act of 2008 (Division C of Pub. L. 110-343, 122 
Stat. 3765 (Oct. 3, 2008)).
---------------------------------------------------------------------------

    The Affordable Care Act (ACA) \25\ 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 ACA added section 715(a)(1) to ERISA and 
section 9815(a)(1) to the Code to incorporate the provisions of part A 
of title XXVII of the PHS Act into ERISA and the Code, and to make them 
applicable to group health plans and health insurance issuers providing 
health insurance coverage in connection with group health plans. The 
PHS Act sections included by these references are sections 2701 through 
2728. The ACA extended MHPAEA to apply to individual health insurance 
coverage and redesignated MHPAEA in the PHS Act as section 2726.\26\ 
Additionally, section 1311(j) of the ACA applies PHS Act section 2726 
to qualified health plans \27\ in the same manner and to the same 
extent as it applies to health insurance issuers and group health 
plans. The ACA also included a requirement for coverage of mental 
health and substance use disorder services, including behavioral health 
treatment, as a category of essential health benefits (EHB).\28\ HHS' 
EHB regulations require health insurance issuers offering non-
grandfathered health insurance coverage in the individual and small 
group markets to comply with MHPAEA and its implementing regulations to 
satisfy the requirement to cover ``mental health and substance use 
disorder services, including behavioral health treatment,'' as part of 
EHB.\29\
---------------------------------------------------------------------------

    \25\ References to the Affordable Care Act or ACA include the 
Patient Protection and Affordable Care Act (Pub. L. 111-148, 123 
Stat. 3028) enacted on March 23, 2010, and the Health Care and 
Education Reconciliation Act of 2010 (Pub. L. 111-152, 124 Stat. 
1029) enacted on March 30, 2010.
    \26\ The requirements of MHPAEA generally apply to both 
grandfathered and non-grandfathered health plans. See section 1251 
of the ACA and its implementing regulations at 26 CFR 54.9815-1251, 
29 CFR 2590.715-1251, and 45 CFR 147.140. Under section 1251 of the 
ACA, grandfathered health plans are exempted only from certain ACA 
requirements enacted in Subtitles A and C of Title I of the ACA. The 
provisions extending MHPAEA requirements to individual health 
insurance coverage and requiring that qualified health plans comply 
with MHPAEA are not included in these sections. However, because 
MHPAEA requirements apply to health insurance coverage offered in 
the small group market only through the requirement to provide EHB, 
which does not apply to grandfathered health plans, the requirements 
of MHPAEA do not apply to grandfathered health plans offered in the 
small group market.
    \27\ A qualified health plan is a health insurance plan that is 
certified by a health insurance exchange that it meets certain 
minimum standards established under the ACA and described in subpart 
C of 45 CFR part 156. See 45 CFR 155.20.
    \28\ Section 1302 of the ACA requires non-grandfathered health 
plans in the individual and small group markets to cover EHB, which 
include items and services in the following ten benefit categories: 
(1) ambulatory patient services; (2) emergency services; (3) 
hospitalization; (4) maternity and newborn care; (5) mental health 
and substance use disorder services, including behavioral health 
treatment; (6) prescription drugs; (7) rehabilitative and 
habilitative services and devices; (8) laboratory services; (9) 
preventive and wellness services and chronic disease management; and 
(10) pediatric services, including oral and vision care. See 45 CFR 
156.115 for description of the benefits a health plan must provide 
to provide EHB.
    \29\ Section 1302(b)(1)(E) of the ACA; 45 CFR 156.115(a)(3).
---------------------------------------------------------------------------

    The Departments published a request for information soliciting 
comments on issues under MHPAEA \30\ and subsequently issued interim 
final regulations to implement the requirements of MHPAEA.\31\ After 
considering the comments, the Departments published the 2013 final 
regulations.\32\ As detailed in the preamble to the proposed rules, in 
the years after the 2013 final regulations were published, the 
Departments provided extensive guidance and compliance assistance 
materials to the regulated community, State regulators, and other 
interested parties to facilitate the implementation and enforcement of

    The CAA, 2021 was enacted by Congress on December 27, 2020,\35\ and 
amended MHPAEA, in part, by expressly requiring group health plans and 
health insurance issuers that provide both medical/surgical benefits 
and mental health or substance use disorder benefits to perform and 
document comparative analyses of the design and application of NQTLs 
that apply to mental health or substance use disorder benefits. The 
statute also requires plans and issuers to make their analyses 
available to the Departments or applicable State authorities, upon 
request, effective February 10, 2021. Additionally, the CAA, 2021 sets 
forth a process by which the Departments must evaluate the requested 
NQTL comparative analyses and enforce the comparative analyses 
requirements and requires the Departments to submit annually to 
Congress and make publicly available a report summarizing the 
comparative analyses requested for review by the Departments.\36\

Implementation and the Consolidated Appropriations Act, 2021 Part 45 
(FAQs Part 45).\37\ As detailed in the preamble to the proposed rules, 
these FAQs provided initial guidance to plans and issuers on these 
amendments to MHPAEA.\38\ Additionally, as required

by the CAA, 2021, the Departments provided reports to Congress on the 
NQTL comparative analyses reviews conducted by the Departments.\39\ 
These reports highlighted that nearly all of the comparative analyses 
reviewed by the Departments during the relevant time periods contained 
insufficient information to support a finding of compliance upon 
initial receipt and reflected common insufficiencies.

    Building on the lessons learned from implementing and enforcing 
MHPAEA, as well as the guidance provided in FAQs Part 45, on August 3, 
2023, the Departments published proposed rules to amend existing MHPAEA 
regulations at 26 CFR 54.9812-1, 29 CFR 2590.712, and 45 CFR 146.136; 
\40\ to add a proposed new regulation at 26 CFR 54.9812-2, 29 CFR 
2590.712-1, and 45 CFR 146.137 in order to codify minimum standards for 
developing NQTL comparative analyses; and to codify HHS-only amendments 
to implement the sunset provision for self-funded non-Federal 
governmental plan elections to opt out of compliance with MHPAEA. On 
September 28, 2023, the Departments extended the comment period that 
was set to expire on October 2, 2023, by 15 days to October 17, 2023, 
to give interested parties additional time to review the proposed rules 
and submit comments.\41\
---------------------------------------------------------------------------

    \40\ 88 FR 51552 (Aug. 3, 2023). On July 25, 2023, DOL, in 
collaboration with HHS and the Treasury, also issued Technical 
Release 2023-01P. The Technical Release set out principles and 
sought public comment to inform future guidance with respect to the 
application of the proposed data collection and evaluation 
requirements to NQTLs related to network composition and a potential 
time-limited enforcement safe harbor for plans and issuers that 
include data in their comparative analyses that demonstrate they 
meet or exceed all the thresholds identified in future guidance with 
respect to NQTLs related to network composition. The Departments 
encouraged interested parties to submit their comments consistent 
with the instructions contained in it separate from any comments 
they submitted in response to the proposed rules. The Departments 
are considering these comments separately and these final rules do 
not respond to those comments. Plans and issuers would be allowed 
adequate time to conform to any future guidance on the type, form, 
and manner of collection and evaluation for the relevant data 
required under the final rules.
    \41\ 88 FR 66728 (Sept. 28, 2023).
---------------------------------------------------------------------------

    The Departments received 9,503 comments that were submitted during 
the comment period \42\ in response to the proposed rules from a wide 
variety of interested parties, including private citizens; consumer and 
advocacy organizations; employers, employee organizations, and other 
plan sponsors; Federal, State, and local officials; health care 
providers and facilities and health systems; health insurance issuers; 
service providers, including managed behavioral health organizations 
(MBHOs), third-party administrators (TPAs), and pharmacy benefit 
managers (PBMs); trade and professional associations; and researchers. 
Many commenters provided detailed feedback on multiple aspects of the 
proposed rules and in response to various specific comment 
solicitations included in the preamble to the proposed rules and the 
request for information.
---------------------------------------------------------------------------

    \42\ The comment period for the proposed rules was extended by 
15 days to October 17, 2023.
---------------------------------------------------------------------------

    In general, many commenters supported the proposed rules, because 
they would formalize and, according to these commenters, provide 
greater clarity on what health plans and issuers must do to comply with 
MHPAEA. Some commenters highlighted that the existing rules were 
insufficient and that the proposed rules were timely and necessary to 
strengthen MHPAEA and ensure fair access to mental health and substance 
use disorder care. Commenters highlighted the importance of the 
proposed rules to participants, beneficiaries, and enrollees, including 
children, teens, young adults, and others living with mental health 
conditions and substance use disorders. Several other commenters, 
however, expressed either opposition or concern regarding the proposed 
rules. Several commenters stated that the proposed rules would increase 
health plan and issuer costs and reduce treatment quality. A few 
commenters recommended the Departments withdraw the proposed rules and 
initiate a new rulemaking process after additional input from 
interested parties.
    After reviewing the comments received during the comment period, 
the Departments are finalizing the proposed rules, with some changes in 
response to comments as described in more detail later in this 
preamble, to ensure that participants, beneficiaries, and enrollees can 
access the mental health and substance use disorder care they need 
without facing greater restrictions than when accessing medical and 
surgical care, consistent with the fundamental purpose of MHPAEA. These 
final rules provide additional clarity to plans and issuers on how to 
comply with MHPAEA's requirements and, as a result, will strengthen the 
protections of MHPAEA. As highlighted earlier in this preamble, since 
the 2013 final regulations, the Departments repeatedly sought input 
from interested parties on MHPAEA's requirements; therefore, the 
Departments decline to withdraw the proposed rules or initiate a new 
rulemaking process after soliciting additional input from interested 
parties. As explained throughout this preamble, the amendments made by 
these final rules are faithful to MHPAEA's parity requirements and 
sensitive to the flexibility plans and issuers have in designing 
benefits for group health plans and health insurance coverage.\43\
---------------------------------------------------------------------------

    \43\ The Departments note that impacts on plan and issuer costs 
are discussed in more detail in the regulatory impact analysis, 
later in this preamble.
---------------------------------------------------------------------------

    Among other things, these final rules:
    <bullet> Make clear that MHPAEA requires that individuals will not 
face greater restrictions on access to mental health and substance use 
disorder benefits as compared to medical/surgical benefits.
    <bullet> Reinforce that health plans and issuers cannot use NQTLs, 
such as prior authorization and other medical management techniques, 
standards related to network composition, or methodologies to determine 
out-of-network reimbursement rates, for mental health and substance use 
disorder benefits, that are more restrictive than the predominant NQTLs 
applied to substantially all medical/surgical benefits in the same 
classification.
    <bullet> Require plans and issuers to collect and evaluate data and 
take reasonable action, as necessary, to address material differences 
in access to mental health and substance use disorder benefits as 
compared to medical/surgical benefits, where the relevant data suggest 
that the NQTL contributes to material differences in access.
    <bullet> Codify the requirement in MHPAEA, as amended by the CAA, 
2021, that health plans and issuers conduct comparative analyses to 
measure the impact of NQTLs. This includes evaluating standards related 
to network composition, out-of-network reimbursement rates, and medical 
management and prior authorization NQTLs.
    <bullet> Prohibit plans and issuers from using discriminatory 
information, evidence, sources, or standards that systematically 
disfavor or are specifically designed to disfavor access to mental 
health and substance use disorder benefits when designing NQTLs.
    <bullet> Implement the sunset provision for self-funded non-Federal 
governmental plan elections to opt out of compliance with MHPAEA.
    As a result, the Departments anticipate that these final rules will 
result in changes in network composition and medical management 
techniques related to mental health and substance use disorder care, 
more robust mental health and substance use disorder provider networks, 
and fewer

[[Page 77590]]

and less restrictive prior authorization requirements for individuals 
seeking mental health and substance use disorder care, as well as 
provide additional clarity and information needed for plans and issuers 
to meet their obligations under MHPAEA and for the Departments and 
States to enforce those obligations.

II. Overview of the Final Rules--Departments of the Treasury, Labor, 
and HHS

    The Departments are issuing these final rules to ensure that 
individuals with mental health conditions and substance use disorders 
can benefit from the full protections afforded to them under MHPAEA, 
while offering clear guidance to plans and issuers on how to comply 
with MHPAEA's requirements. These final rules amend certain provisions 
of existing MHPAEA regulations at 26 CFR 54.9812-1, 29 CFR 2590.712, 
and 45 CFR 146.136 to incorporate new and revised definitions of key 
terms, as well as to specify the steps that plans and issuers must take 
to meet their obligations under MHPAEA. These final rules also add new 
regulations at 26 CFR 54.9812-2, 29 CFR 2590.712-1, and 45 CFR 146.137 
codifying minimum standards for developing NQTL comparative analyses to 
assess whether an NQTL, as written and in operation, complies with 
MHPAEA's requirements and setting forth the content elements of 
comparative analyses and the period for plans and issuers to respond to 
a request from the Departments to submit their comparative analyses. 
Additionally, in these final rules, HHS finalizes an amendment to 45 
CFR 147.160 to specify that the final regulations at 45 CFR 146.137 
apply to individual health insurance coverage offered by a health 
insurance issuer in the same manner and to the same extent that the 
regulations apply to health insurance coverage offered by a health 
insurance issuer in connection with a group health plan in the large 
group market.\44\ Consistent with the existing text at 45 CFR 
147.160(a), HHS is also extending the same requirements and framework 
outlined in the amendments to 45 CFR 146.136 in these final rules to 
individual health insurance coverage in the same manner and to the same 
extent as the amendments that apply to group health insurance coverage. 
Finally, HHS is finalizing amendments to 45 CFR 146.180 to reflect the 
sunset of the election option for self-funded non-Federal governmental 
plans to opt out of compliance with MHPAEA, consistent with changes 
made by the CAA, 2023 to PHS Act section 2722(a)(2).\45\
---------------------------------------------------------------------------

    \44\ Non-grandfathered health insurance coverage offered by a 
health insurance issuer in connection with a group health plan in 
the small group market is required to comply with the requirements 
under PHS Act section 2726 to satisfy the requirement to provide 
coverage for mental health and substance use disorder services, 
including behavioral health treatment, as part of EHB, and as such 
will also be required to comply with the comparative analysis 
requirements finalized under 45 CFR 146.137. See 45 CFR 
156.115(a)(3).

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

A. Amendments to Existing Regulations at 26 CFR 54.9812-1, 29 CFR 
2590.712, and 45 CFR 146.136

1. Purpose Section--26 CFR 54.9812-1(a)(1), 29 CFR 2590.712(a)(1), and 
45 CFR 146.136(a)(1)
    In the preamble to the proposed rules, the Departments stated that 
the fundamental purpose of the MHPAEA statute, the 2013 final 
regulations, and the proposed rules is to ensure that participants and 
beneficiaries in a group health plan or in group health insurance 
coverage offered by a health insurance issuer that offers mental health 
or substance use disorder benefits are not subject to greater 
restrictions when seeking those benefits than when seeking medical/
surgical benefits under the terms of the plan or coverage. The 
Departments also stated that the fundamental purpose of MHPAEA should 
serve as the guiding principle for plans and issuers as they work to 
comply with the requirements of the law and its implementing 
regulations. Accordingly, the Departments proposed to add a purpose 
section to the regulations, specifying this fundamental purpose, and 
that MHPAEA and its implementing regulations should be interpreted in a 
manner that is consistent with this purpose.
    Many commenters supported the addition of the purpose section and 
the principles it addressed, including the goal of increasing access to 
mental health and substance use disorder benefits, to ensure equal 
treatment for mental health and substance use disorder benefits and 
medical/surgical benefits. A few commenters expressed opposition to the 
proposed purpose section, arguing that its language goes beyond the 
intent of MHPAEA (as Congress did not direct the Departments to provide 
a purpose in regulations, either initially or in later amendments).
    The purpose section is important to highlight the overall goals of 
MHPAEA and to emphasize that the provisions of the 2013 final 
regulations, as amended by these final rules, should be interpreted in 
light of these goals. Congress provided authority to the Departments to 
``promulgate such regulations as may be necessary or appropriate to 
carry out the provisions of'' chapter 100 of the Code, part 7 of ERISA, 
and title XXVII of the PHS Act, including MHPAEA.\46\ MHPAEA was 
enacted to address barriers to access to mental health and substance 
use disorder benefits as compared to medical/surgical benefits. These 
final rules implement MHPAEA's requirements and provide clarifying text 
to promote compliance with the law. The Departments are finalizing the 
purpose section as proposed, with minor changes in response to 
comments.
---------------------------------------------------------------------------

    \46\ See Code section 9833, ERISA section 734, and PHS Act 
section 2792.
---------------------------------------------------------------------------

    Several commenters requested that the reference to ``generally 
comparable'' medical/surgical benefits in the proposed purpose section 
be revised to refer to the classification of benefits. These commenters 
noted that, consistent with the 2013 final regulations, evaluation of a 
plan's or issuer's MHPAEA compliance is assessed within the relevant 
classification of benefits, and that use of the term ``comparable,'' 
which is used in the 2013 final regulations and amendments made to 
MHPAEA by the CAA, 2021 with respect to requirements for NQTLs, is 
confusing and should be revised.
    The Departments agree with commenters who noted that use of the 
term ``comparable'' can be confusing when used in this context, because 
compliance with the requirements for financial requirements, 
quantitative treatment limitations, and NQTLs has historically been 
determined within one of the six classifications of benefits.\47\ 
Therefore, these final rules remove the reference to ``generally 
comparable'' medical/surgical benefits and instead specify that plans 
and issuers must not design or apply financial requirements and 
treatment limitations that impose a greater burden on access (that is, 
are more restrictive) to mental health or substance use disorder 
benefits under the plan or coverage than they impose on access to 
medical/surgical benefits in the same classification of benefits. The

[[Page 77591]]

Departments are finalizing the purpose section without any other 
substantive changes, but with a few minor clarifications to ensure that 
terms are used consistently with and accurately describe other parts of 
these final rules.
---------------------------------------------------------------------------

    \47\ The six classifications of benefits listed at 26 CFR 
54.9812-1(c)(2)(ii)(A), 29 CFR 2590.712(c)(2)(ii)(A), and 45 CFR 
146.136(c)(2)(ii)(A) include inpatient, in-network; inpatient, out-
of-network; outpatient, in-network; outpatient, out-of-network; 
emergency care, and prescription drugs. Special rules for multi-
tiered prescription drug benefits, multiple network tiers, and 
permissible sub-classifications for office visits, separate from 
other outpatient services, are addressed at 26 CFR 54.9812-
1(c)(3)(iii), 29 CFR 2590.712(c)(3)(iii), and 45 CFR 
146.136(c)(3)(iii).
---------------------------------------------------------------------------

2. Meaning of Terms--26 CFR 54.9812-1(a)(2), 29 CFR 2590.712(a)(2), and 
45 CFR 146.136(a)(2)
a. Medical/Surgical Benefits, Mental Health Benefits, and Substance Use 
Disorder Benefits
    Under the statute and the 2013 final regulations, the term 
``medical/surgical benefits'' means benefits for medical or surgical 
services as defined under the terms of the plan or health insurance 
coverage but does not include mental health or substance use disorder 
benefits. The 2013 final regulations further provide that the term must 
be defined in accordance with applicable Federal and State law, and 
that any condition defined by the plan or coverage as being or as not 
being a medical/surgical condition must be defined to be consistent 
with generally recognized independent standards of current medical 
practice (for example, the most current version of the International 
Classification of Diseases (ICD) or State guidelines).
    The proposed rules generally retained the first sentence of the 
2013 final regulations' definition of ``medical/surgical benefits,'' 
\48\ but amended the definition to provide that, notwithstanding this 
first sentence, any condition or procedure defined by the plan or 
coverage as being or not being a medical condition or surgical 
procedure must be defined consistent with generally recognized 
independent standards of current medical practice (for example, the 
most current version of the ICD). Further, the proposed rules stated 
that, to the extent that generally recognized independent standards of 
current medical practice do not address whether a condition or 
procedure is a medical condition or surgical procedure, plans and 
issuers may define the condition or procedure as medical/surgical 
benefits, as long as such definitions are in accordance with applicable 
Federal and State law. The Departments also proposed to remove the 
reference to State guidelines in the definition of the term in the 2013 
final regulations, both to make the definitions more consistent with 
the statute, and to minimize situations where differences between 
generally recognized independent standards of current medical practice 
and State guidelines create conflicts and improperly limit protections 
under MHPAEA.
---------------------------------------------------------------------------

    \48\ Under the 2013 final regulations, the term ``medical/
surgical benefits'' means benefits with respect to items or services 
for medical conditions or surgical procedures, as defined under the 
terms of the plan or health insurance coverage and in accordance 
with applicable Federal and State law, but does not include mental 
health or substance use disorder benefits. 26 CFR 54.9812-1(a), 29 
CFR 2590.712(a), and 45 CFR 146.136(a).
---------------------------------------------------------------------------

    The Departments also proposed to make similar changes to the 
definitions of ``mental health benefits'' and ``substance use disorder 
benefits'' by amending the first sentence of each definition and 
removing the references to State guidelines, consistent with the 
changes described above for ``medical/surgical benefits.'' \49\ For 
purposes of the requirement that any condition or disorder defined by 
the plan or coverage as being or not being a mental health condition 
must be defined to be consistent with generally recognized independent 
standards of current medical practice, the proposed rules stated that 
the plan's or coverage's definition must include all conditions covered 
under the plan or coverage, except for substance use disorders, that 
fall under any of the diagnostic categories listed in the mental, 
behavioral, and neurodevelopmental disorders chapter (or equivalent 
chapter) of the most current version of the ICD or that are listed in 
the most current version of the American Psychiatric Association (APA) 
Diagnostic and Statistical Manual of Mental Disorders (DSM). Similarly, 
the proposed rules stated that the plan's or coverage's definition of 
``substance use disorder benefits'' must include all disorders covered 
under the plan or coverage that fall under any of the diagnostic 
categories listed as a mental or behavioral disorder due to 
psychoactive substance use (or equivalent category) in the mental, 
behavioral, and neurodevelopmental disorders chapter (or equivalent 
chapter) of the most current version of the ICD or that are listed as a 
Substance-Related and Addictive Disorder (or equivalent category) in 
the most current version of the DSM. The proposed rules solicited 
comments on whether any additional clarification is needed on how State 
law may interact with the proposed amended definitions of ``medical/
surgical benefits,'' ``mental health benefits'' and ``substance use 
disorder benefits.''
---------------------------------------------------------------------------

    \49\ Consistent with the statute and the 2013 final regulations, 
the Departments note that references to ``mental health and 
substance use disorder benefits'' and ``mental health or substance 
use disorder benefits'' throughout these final rules are intended to 
have the same meaning as the terms ``mental health benefits'' and 
``substance use disorder benefits'' in combination.
---------------------------------------------------------------------------

    In general, many commenters supported modifying these key 
definitions in existing MHPAEA regulations by specifying that, to be 
consistent with generally recognized independent standards of current 
medical practice, the terms of the plan or coverage must accord with 
appropriate chapters of the ICD or DSM. Many commenters generally 
supported requiring plans and issuers to follow the ICD or DSM, 
reasoning that both are generally accepted, peer-reviewed, nonprofit 
professional standards for diagnosis and descriptions of medical 
conditions, mental health conditions, and substance use disorders, and 
that following these authoritative and comprehensive diagnostic tools 
promotes uniform and standard application of MHPAEA to mental health 
conditions and substance use disorders. Several commenters noted that 
these changes would significantly improve clarity and would increase 
access to care, especially for intellectual and neurodevelopmental 
disorders, including dementia and autism spectrum disorder (ASD). 
Another commenter recommended clarifying whether plans and issuers are 
required to consider both the ICD and the DSM in categorizing benefits 
for the purposes of the proposed rules. One commenter added that the 
Departments' proposal to align and clarify the definitions of ``mental 
health benefits'' and ``substance use disorder benefits'' would ensure 
parity between the relevant terms and protect the application of MHPAEA 
for conditions and disorders recognized under independent standards of 
current medical practice. Another commenter expressing support reasoned 
that the proposed amendments would clearly specify how mental health 
conditions and substance use disorders must be defined for MHPAEA 
compliance purposes and minimize contradictions with State guidelines 
that now limit MHPAEA protections. The commenter also remarked that 
self-insured plans frequently include language from State-level 
mandated benefit requirements prevalent in the plan's geographic area 
that may not be MHPAEA-compliant.
    Several commenters supported the removal of any reference to State 
guidelines to prevent situations in which contradictions between 
Federal and State guidelines would result in a loss of protections 
under MHPAEA. One commenter wrote that State law definitions often 
predate MHPAEA, may conflict with ICD and DSM standards, and should not 
be the operable standard, while others stated that State

[[Page 77592]]

guidelines should not be given precedence over Federal regulations to 
ensure that MHPAEA's protections are not subverted. However, one 
commenter urged that the Departments continue allowing plans and 
issuers to use State guidelines to inform the definitions of ``medical/
surgical benefits,'' ``mental health benefits,'' and ``substance use 
disorder benefits,'' regardless of whether State law is consistent with 
generally recognized independent standards of current medical practice. 
The commenter noted that independent standards of medical practice vary 
and change over time and are not established with the same intents and 
purposes as State laws. The commenter also stated that States have been 
the traditional regulators of health insurance issuers when it comes to 
interpretive and enforcement matters, even for coverage issues subject 
to Federal law (such as the ACA and MHPAEA). Another commenter 
supported the clarification that, when the DSM or ICD does not indicate 
whether a condition or disorder is a mental health condition or 
substance use disorder, plans and issuers may define the condition or 
disorder in accordance with applicable Federal and State law.
    In the proposed rules, the Departments noted that, to the extent 
applicable State law or generally recognized independent standards of 
current medical practice define a condition or disorder as a mental 
health condition or substance use disorder, plans and issuers must 
treat all benefits for the condition or disorder as mental health 
benefits or substance use disorder benefits, respectively, for purposes 
of analyzing parity and ensuring compliance with MHPAEA. To better 
understand interested parties' concerns in implementing this 
requirement, the Departments solicited comments on potential challenges 
in applying MHPAEA to all benefits for a mental health condition or 
substance use disorder where a specific item or service can be 
furnished for both medical conditions or surgical procedures and mental 
health conditions or substance use disorders, and whether additional 
clarifications or modifications to the proposed definitions are 
necessary.
    In response to this comment solicitation, commenters identified 
several instances in which an individual with a mental health or 
substance use disorder diagnosis may need a particular treatment for 
that condition or disorder that may also be provided to treat a medical 
condition. For example, ASD \50\ might be treated with speech and 
occupational therapy, which is also used to treat some medical 
conditions. Additionally, an eating disorder might require medical 
nutrition therapy, which could also be used to treat a medical 
condition (such as for the treatment of obesity or diabetes). Moreover, 
with respect to benefits for prescription drugs, a commenter noted that 
claims for reimbursement generally do not include diagnosis 
information. Some commenters explained that many specific prescription 
drugs are prescribed for mental health conditions and substance use 
disorders, as well as for medical/surgical conditions, and including 
diagnosis information would require a range of different entities and 
interested parties to change their current practice. Commenters also 
recommended several methods under which the rules could allow plans and 
issuers to characterize items and services as medical/surgical 
benefits, mental health benefits, or substance use disorder benefits. 
One commenter suggested items and services be characterized as either 
mental health benefits, substance use disorder benefits, or medical/
surgical benefits based on the condition or disorder being treated. 
Similarly, another commenter suggested that items and services be 
characterized as mental health benefits or substance use disorder 
benefits when a claim's primary diagnosis is a mental health condition 
or substance use disorder, respectively, as that diagnosis is driving 
the treatment provided. Alternatively, several commenters suggested the 
rules could be aligned with existing Centers for Medicare & Medicaid 
Services (CMS) guidance on MHPAEA compliance for Medicaid and the 
Children's Health Insurance Program (CHIP) so that plans and issuers 
could use a ``reasonable method'' for defining services commonly used 
to treat both medical conditions and mental health conditions or 
substance use disorders, for example, by using the plan's or issuer's 
annual claims experience to determine its spending on the service in 
question.\51\
---------------------------------------------------------------------------

    \50\ As discussed later in this preamble, the Departments stated 
in the proposed rules and reiterate in these final rules that ASD is 
a mental health condition for purposes of MHPAEA.

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

    After reviewing comments received from interested parties, the 
Departments are finalizing the definitions of ``medical/surgical 
benefits,'' ``mental health benefits'' and ``substance use disorder 
benefits'' as proposed. While plans and issuers have some discretion in 
defining mental health benefits and substance use disorder benefits, 
this discretion must be exercised in a manner that comports with 
generally recognized independent standards of current medical practice, 
and the definitions in these final rules include sufficient safeguards 
to protect against defining a benefit in a manner that could result in 
limitations on access to mental health or substance use disorder 
benefits that are more restrictive than those applicable to medical/
surgical benefits. Further, while the Departments acknowledge the 
concern that independent standards of current medical practice change 
over time and may not have been established with the same intents and 
purposes as State law or State guidelines, such standards better ensure 
that plans and issuers define mental health conditions and substance 
use disorders in a manner consistent with the purposes of MHPAEA. The 
Departments agree with one commenter's concern that some State laws, in 
particular, might predate MHPAEA. As a result, such State laws might 
not offer the same safeguards to access to mental health or substance 
use disorder benefits as MHPAEA. The Departments also note that plans 
and issuers are required to ensure that the definitions used in the 
plan or coverage are consistent with the appropriate chapters of the 
most current version of either the ICD or the DSM.
    Additionally, while States generally are the traditional regulators 
of health insurance issuers, with respect to MHPAEA, the Departments 
are not persuaded that this necessitates permitting plans and issuers 
to use definitions of ``medical/surgical benefits,'' ``mental health 
benefits'' and ``substance use disorder benefits'' that are solely tied 
to applicable State law or guidelines. The definitions of ``medical/
surgical benefits,'' ``mental health benefits,'' and ``substance use 
disorder benefits'' in these final rules preserve the ability of plans 
and issuers to use applicable Federal and State law to inform their 
definitions, but only to the extent that those laws are consistent with 
generally recognized independent standards of current medical 
practice.\52\
---------------------------------------------------------------------------

    \52\ The final rules also permit plans and issuers to use 
applicable Federal and State law to inform their definitions to the 
extent generally recognized independent standards of current medical 
practice do not address whether a condition or disorder is a medical 
condition, surgical procedure, mental health condition, or substance 
use disorder.
---------------------------------------------------------------------------

    These final rules do not make any changes to the proposed 
definitions to specifically address how plans and

[[Page 77593]]

issuers should apply MHPAEA where a specific item or service may be 
used to treat both medical conditions or surgical procedures as well as 
mental health conditions or substance use disorders. These final rules, 
like the proposed rules and the 2013 final regulations, require plans 
and issuers to continue to characterize items and services as medical/
surgical benefits, mental health benefits, or substance use disorder 
benefits based on the condition or disorder being treated. This 
interpretation is the most appropriate reading of the definitions of 
medical/surgical benefits, mental health benefits, and substance use 
disorder benefits, consistent with the statute and the purpose of 
MHPAEA. The Departments note that the existing CMS mental health and 
substance use disorder parity guidance for Medicaid and CHIP identified 
by several commenters addresses long-term services and supports 
provided through Medicaid and CHIP, not items and services covered by 
group health plans and health insurance coverage. The Departments 
reiterate that, if a plan (or coverage) defines a condition or disorder 
as a mental health condition or substance use disorder, plans and 
issuers subject to these final rules must treat all benefits for the 
condition or disorder as mental health benefits or substance use 
disorder benefits, respectively, for purposes of compliance with 
MHPAEA. The Departments decline to adopt the alternative methods 
suggested by commenters that plans and issuers might use to 
characterize items and services as medical/surgical benefits, mental 
health benefits, or substance use disorder benefits, as they may be 
insufficient to ensure consistency with generally recognized 
independent standards of current medical practice and in accordance 
with applicable State and Federal law. Furthermore, while the 
Departments acknowledge the particular challenges with respect to 
prescription drug benefits due to the lack of diagnostic information on 
claims for reimbursement, these final rules, similar to the 2013 final 
regulations, provide plans and issuers enough flexibility to make 
decisions about how to classify items and services, including 
prescription drugs, as either mental health benefits, substance use 
disorder benefits, or medical/surgical benefits.
    To provide guidance to plans and issuers on how to ensure that they 
define benefits consistent with generally recognized independent 
standards of current medical practice, the proposed rules proposed 
separate definitions of the ICD and DSM. Specifically, the Departments 
proposed that the ICD would be defined as the World Health 
Organization's International Classification of Diseases adopted by HHS 
through 45 CFR 162.1002 or successor regulations, and the DSM would be 
defined as the APA's Diagnostic and Statistical Manual of Mental 
Disorders. The proposed definitions also specified, for purposes of the 
definition, which version of the ICD or DSM is the most current as of a 
particular date. This was intended to provide clarity on when a plan or 
issuer would be required to begin to rely on a new version of the ICD 
or DSM after it is released and allow sufficient time after the 
adoption of an updated version of the ICD or DSM for a plan or issuer 
to update the terms of its plan or coverage to be consistent with any 
changes made from the previous version. The proposed definitions stated 
that the most current version of the ICD or DSM, respectively, would be 
the version applicable no earlier than the date that is 1 year before 
the first day of the applicable plan year; however, the proposed rules 
would permit the use of an updated version before the plan or issuer is 
required to use it. Finally, in recognition of the fact that future 
versions of the ICD or DSM may include revisions to the categories of 
conditions or disorders or chapters listed in the proposed amended 
definitions for ``mental health benefits'' and ``substance use disorder 
benefits,'' the proposed amended definitions referred to ``equivalent 
categories'' and ``equivalent chapters.''
    The Departments received several comments on the proposed 
definitions of the terms ``ICD'' and ``DSM,'' with some commenters 
suggesting alternatives to the language identifying the most current 
versions of the DSM and ICD. One commenter suggested specifying that if 
a new version of the DSM or ICD is published in the middle of a plan 
year, then plans and issuers must use the updated version by the start 
of the next plan year. One commenter suggested that the most current 
version of an independent standard should encompass any version 
commonly in use among providers, and any version used in the most 
recent claims experience available to plans and issuers.
    The Departments are finalizing the definition of ``ICD'' as 
proposed, with clarifications with respect to the most current version 
of the ICD. Specifically, under these final rules, the most current 
version of the ICD as of November 22, 2024, the effective date of these 
final rules, is the International Classification of Diseases, 10th 
Revision, Clinical Modification adopted for the period beginning on 
October 1, 2015, through HHS regulations at 45 CFR 162.1002 (or 
successor regulations).\53\ Any subsequent version of the ICD adopted 
through 45 CFR 162.1002 (or successor regulations) after November 22, 
2024, will be considered the most current version beginning on the 
first day of the plan year that is one year after the date the 
subsequent version is adopted.
---------------------------------------------------------------------------

    \53\ These HHS regulations implement section 212 of the 
Protecting Access to Medicare Act of 2014 by setting compliance 
dates for the 10th Revision of the ICD for diagnosis and procedure 
coding.
---------------------------------------------------------------------------

    The Departments are also finalizing the definition of ``DSM'' as 
proposed, with similar clarifications, which note that the most current 
version as of November 22, 2024, the effective date of these final 
rules, is the Diagnostic and Statistical Manual of Mental Disorders, 
Fifth Edition, Text Revision published in March 2022. A subsequent 
version of the DSM published after November 22, 2024, will be 
considered the most current version beginning on the first day of the 
plan year that is one year after the date the subsequent version is 
published (as the DSM is published, rather than made applicable). 
Consistent with this clarification, if a new version of the DSM is 
published in the middle of a plan year, plans and issuers will have at 
least one full year before they are required to use the updated version 
with respect to a plan year. For example, if a new version of the DSM 
is published on August 1, 2025, for a calendar year plan, that version 
of the DSM would be the most current version with respect to the plan 
year beginning on January 1, 2027.
    It is important to provide specificity with regard to the relevant 
versions of the ICD and DSM instead of allowing the use of multiple 
versions, as suggested by commenters, to ensure that plans and issuers 
do not select a version that restricts access to mental health and 
substance use disorder benefits in a manner that is more restrictive 
than access to medical/surgical benefits. Because the Departments 
understand that the ICD and DSM are both broadly utilized by providers 
and facilities, as well as plans and issuers, and were referenced in 
the 2013 final regulations, these final rules continue to rely on such 
standards.
    Finally, the preamble to the proposed rules noted that interested 
parties requested that the Departments confirm whether specific 
conditions are mental health conditions for purposes of MHPAEA. 
Consistent with the 2013 final regulations and section 13007 of

[[Page 77594]]

the 21st Century Cures Act (Cures Act),\54\ the Departments confirmed 
in the proposed rules that eating disorders, such as anorexia nervosa, 
bulimia nervosa, and binge-eating disorder, are mental health 
conditions under generally recognized independent standards of current 
medical practice.\55\ Similarly, the proposed rules made clear that, 
for purposes of MHPAEA, ASD is a mental health condition under 
generally recognized independent standards of current medical 
practice.\56\ Therefore, benefits for these disorders are considered 
mental health benefits, and subject to the protections of MHPAEA and 
its implementing regulations, including these final rules.
---------------------------------------------------------------------------

    \54\ Public Law 114-255, 130 Stat. 1033 (Dec. 13, 2016). Section 
13007 of the Cures Act states that, if a plan or an issuer offering 
group or individual health insurance coverage provides coverage for 
eating disorder benefits, including residential treatment, such 
group health plan or health insurance issuer shall provide such 
benefits consistent with the requirements of MHPAEA.
    \55\ See, e.g., DSM Disorders (5th ed.), Section II: Diagnostic 
Criteria and Codes, Feeding and Eating Disorders; ICD-10, Chapter V: 
Mental and behavioral disorders, Code F50: Eating disorders.
    \56\ DSM (5th ed.), Section II: Diagnostic Criteria and Codes, 
Autism Spectrum Disorder.
---------------------------------------------------------------------------

    The Departments also solicited comments on other specific mental 
health conditions or substance use disorders that may warrant 
additional clarification for purposes of analyzing parity and ensuring 
compliance with MHPAEA. The Departments received only a few comments in 
response, including a request to clarify whether gender dysphoria is a 
mental health condition. Because the most current versions of both the 
ICD and DSM include gender dysphoria as a mental health condition as of 
the time of the issuance of these final rules, benefits for this 
condition are currently subject to the protections of MHPAEA and its 
implementing regulations, consistent with the framework described 
earlier in this preamble.\57\

b. Processes, Strategies, Evidentiary Standards, and Factors
    The proposed rules included proposed new definitions of terms used 
in paragraph (c)(4)(i) of the 2013 final regulations, which states that 
a plan or issuer may not impose an NQTL with respect to mental health 
or substance use disorder benefits in any classification unless, under 
the terms of the plan (or health insurance coverage) as written and in 
operation, any ``processes,'' ``strategies,'' ``evidentiary 
standards,'' or other ``factors'' used in applying the NQTL to mental 
health or substance use disorder benefits in the classification are 
comparable to, and are applied no more stringently than, those used in 
applying the limitation with respect to medical/surgical benefits in 
the same classification. These terms and the corresponding standard 
were incorporated into MHPAEA's statutory language in the amendments 
made by the CAA, 2021.\58\ Because the Departments heard from 
interested parties prior to the issuance of the proposed rules that it 
can be difficult to determine what constitute relevant processes, 
strategies, evidentiary standards, and other factors, the Departments 
proposed definitions of these terms and included an illustration of the 
interaction of the definitions of these terms in the preamble to the 
proposed rules. The illustration described how a plan might rely on 
various combinations of processes, strategies, evidentiary standards, 
and other factors in designing and applying an NQTL, and gave examples 
of each term. The Departments also solicited comments on the proposed 
definitions, including any alternate definitions or additional 
clarifications that should be considered.
---------------------------------------------------------------------------

    \58\ Code section 9812(a)(8)(A), ERISA section 712(a)(8)(A), and 
PHS Act section 2726(a)(8)(A).
---------------------------------------------------------------------------

    In general, many commenters supported the proposed definitions of 
these key terms, which they described as foundational to the 
development of sufficient comparative analyses and necessary to hold 
plans and issuers accountable for discriminatory NQTLs. Several 
commenters described widespread misinterpretation by plans and issuers 
of the meaning of these key terms. Other commenters wrote that the 
proposed definitions would help clarify the difference between 
``factors'' and ``evidentiary standards,'' and draw a clear distinction 
between ``strategies'' and ``processes,'' which relate, respectively, 
to plans' and issuers' approaches to the design of an NQTL, and to 
their application of an NQTL. Other commenters stated that the 
definitions of these terms should clearly distinguish between each 
component of a plan's or issuer's required comparative analysis and 
assign each step of the analysis to a particular component of the 
comparative analysis. Additionally, a commenter requested more specific 
examples of processes and evidentiary standards, and the differences 
between factors and evidentiary standards. One commenter stated that 
the proposed definitions are not coherent as applied to network 
contracting activities, development of reimbursement methodologies, or 
most other network composition NQTLs. This commenter claimed that there 
is no algorithmic approach to decision making that can be documented 
and requested the Departments to provide guidance on how the many 
activities involved in constructing provider networks and provider 
reimbursements across different plan types, service settings, and 
reimbursement methodologies should be categorized.
    As stated in the preamble to the proposed rules, the proposed 
definitions for the terms ``processes,'' ``strategies,'' ``evidentiary 
standards,'' and ``factors'' are intended to further clarify how to 
properly apply and distinguish between these terms, and to help 
facilitate proper comparisons between the design and application of 
NQTLs to medical/surgical benefits and mental health and substance use 
disorder benefits in the same classification, compliance with the 
requirements related to NQTLs, and the development of sufficient 
comparative analyses, as required under the CAA, 2021 and these final 
rules. The definitions in these final rules improve clarity and add 
specificity to the terms used in MHPAEA, as amended by the CAA, 2021, 
to reduce misinterpretations, and are consistent with the requirements 
in these final rules that set forth the manner in which plans and 
issuers are required to perform and document comparative analyses, 
discussed later in this preamble. The Departments also provide 
additional guidance on how plans and issuers must comply with the 
provisions of these final rules with respect to NQTLs related to 
network composition,\59\ later in this preamble.
---------------------------------------------------------------------------

    \59\ The term ``NQTLs related to network composition'' generally 
refers to the NQTLs listed in 26 CFR 54.9812-1(c)(4)(ii)(D), 29 CFR 
2590.712(c)(4)(ii)(D), and 45 CFR 146.136(c)(4)(ii)(D) of these 
final rules: standards related to network composition, including but 
not limited to standards for provider and facility admission to 
participate in a network or for continued network participation, 
including methods for determining reimbursement rates, credentialing 
standards, and procedures for ensuring the network includes an 
adequate number of each category of provider and facility to provide 
services under the plan or coverage.
---------------------------------------------------------------------------

    The Departments note that nothing in these final rules requires an 
``algorithmic'' decision making process; however, plans and issuers 
must perform and document their comparative analyses as required under 
26 CFR 54.9812-2, 29 CFR 2590.712-1, and 45 CFR 146.137 to show that 
the processes, strategies, evidentiary standards, and other factors 
used in designing or applying an NQTL to mental health and substance 
use

[[Page 77595]]

disorder benefits, as written and in operation, are comparable to, and 
are applied no more stringently than, the processes, strategies, 
evidentiary standards, and other factors used in designing or applying 
the NQTL to medical/surgical benefits in the relevant classification. 
Additionally, anything used by a plan or issuer to design or apply an 
NQTL should be considered a process, strategy, evidentiary standard, or 
factor (or information, evidence, sources, or standards on which a 
factor or evidentiary standard is based), consistent with the 
Departments' broad interpretation of these terms.
    Under the proposed rules, the Departments proposed that evidentiary 
standards generally would not be considered factors, but instead would 
be considered or relied upon in designing or applying a factor. The 
Departments noted that, although the framework established in the 2013 
final regulations treated the terms within the phrase ``processes, 
strategies, evidentiary standards, and other factors'' as having 
overlapping meanings (and the term ``other factors'' was utilized as a 
catch-all), the CAA, 2021 added to MHPAEA other references to factors 
and evidentiary standards that indicate Congress meant to distinguish 
between them.\60\ The Departments requested comments on this approach 
to defining evidentiary standards separately from factors, including 
whether there are any circumstances under which an evidentiary standard 
should also be considered a factor under the framework outlined in the 
proposed rules, but did not receive any specific comments on this 
issue. Therefore, under these final rules, consistent with the proposed 
rules, evidentiary standards are not considered to be factors.
---------------------------------------------------------------------------

    \60\ The preamble to the proposed rules noted that, for example, 
Code section 9812(a)(8)(A)(iii), ERISA section 712(a)(8)(A)(iii), 
and PHS Act section 2726(a)(8)(A)(iii) refer to the evidentiary 
standards that are used for the factors to determine that an NQTL 
will apply to benefits, and those provisions go on to distinguish 
between factors and any other sources or evidence relied upon to 
design or apply an NQTL. See 88 FR 51552, 51567 (Aug. 3, 2023).
---------------------------------------------------------------------------

    The proposed rules provided that the term ``evidentiary standards'' 
would mean any evidence, sources, or standards that a plan or issuer 
considered or relied upon in designing or applying a factor with 
respect to an NQTL, including specific benchmarks or thresholds. The 
proposed definition further provides that evidentiary standards may be 
empirical, statistical, or clinical in nature, and include sources 
acquired or originating from an objective third party, such as 
recognized medical literature, professional standards and protocols 
(which may include comparative effectiveness studies and clinical 
trials), published research studies, payment rates for items and 
services (such as publicly available databases of the ``usual, 
customary, and reasonable'' rates paid for items and services), and 
clinical treatment guidelines. The proposed definition also provides 
that evidentiary standards would include internal plan or issuer data, 
such as claims or utilization data or criteria for assuring a 
sufficient mix and number of network providers, and benchmarks or 
thresholds, such as measures of excessive utilization, cost levels, 
time or distance standards, or network participation percentage 
thresholds.
    One commenter recommended not including specific benchmarks or 
thresholds and professional standards and protocols in the definition 
of the term ``evidentiary standards.'' The commenter noted that many 
plans and issuers do not define their evidentiary standards numerically 
and that finalizing the definition as proposed could require plans and 
issuers to do so, thereby compelling plans and issuers not to use 
relevant, critical data in the development of their NQTLs. The 
commenter also remarked that including professional standards and 
protocols in the definition would require plans and issuers to 
incorporate potentially unproven medical guidance as a standard to 
dictate mental health or substance use disorder benefits, which could 
override common medical management practices. The commenter added that, 
if the reference to professional standards and protocols is retained, 
the Departments should clarify that the definition of ``evidentiary 
standards'' does not imply that all professional standards and 
protocols must be referenced or that benchmarks or thresholds are 
required to be applied to professional standards and protocols.
    The Departments are finalizing the definition of ``evidentiary 
standards'' as proposed. The definition is consistent with the use of 
the term by Congress in the amendments made to MHPAEA by the CAA, 2021. 
The definition of the term ``evidentiary standards'' does not require 
plans and issuers to define their evidentiary standards numerically, 
nor does it imply that all professional standards and protocols must be 
referenced or that benchmarks or thresholds are required to be applied 
to professional standards and protocols (for example, where the 
standards are qualitative in nature). However, to the extent these 
types of evidentiary standards are used to design or apply an NQTL, 
they must be analyzed for compliance with MHPAEA. The list of examples 
of evidentiary standards included in the definition is not intended to 
be exhaustive, nor are any of the evidentiary standards listed required 
to be considered or relied upon in designing or applying a factor with 
respect to an NQTL.
    In the proposed rules, the Departments proposed that the definition 
of the term ``factors'' be read broadly, so that factors are all 
information, including processes and strategies (but not evidentiary 
standards), that a plan or issuer considered or relied upon to design 
an NQTL or to determine whether or how the NQTL applies to benefits 
under the plan or coverage. The Departments noted that by defining the 
term ``factor'' broadly, the Departments' intention was to capture any 
information used to design or apply an NQTL (other than evidentiary 
standards), regardless of whether a plan or issuer believes that 
information could also be characterized as a ``process'' or a 
``strategy,'' as those terms were proposed to be defined. The 
Departments proposed that the term ``factors'' includes information 
(but not evidentiary standards) that the plan or issuer considered but 
rejected, consistent with previous guidance on MHPAEA in the context of 
the documents or plan information the Departments consider relevant to 
a compliance determination.\61\ The proposed definition also provided 
examples of factors, which include, but are not limited to, provider 
discretion in determining diagnosis or type or length of treatment; 
clinical efficacy of any proposed treatment or service; licensing and 
accreditation of providers; claim types with a high percentage of 
fraud; quality measures; treatment outcomes; severity or chronicity of 
condition; variability in the cost of an episode of treatment; high 
cost growth; variability in cost and quality; elasticity of demand; and 
geographic location.

specific underlying processes, strategies, evidentiary standards, 
and other factors (including, but not limited to, all evidence) 
considered by the plan (including factors that were relied upon and 
were rejected) in determining that the NQTL will apply to a 
particular mental health and substance use disorder benefit or any 
medical/surgical benefits within the benefit classification at 
issue.

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

[[Page 77596]]

    With respect to the ``broad'' reading of the term ``factor,'' a 
commenter stated that the proposed definition subsumes ``processes'' 
and ``strategies,'' and suggested eliminating or clarifying this 
distinction with additional guidance. The commenter also remarked that 
the broad definition of ``factor'' would make the multiple steps in a 
comparative analysis less distinguishable, and the requirement that 
plans identify, define, and describe the use of every factor in the 
design or application of an NQTL unworkably expansive. A few commenters 
remarked that the breadth of the definition of ``factor'' makes it 
unclear how a plan or issuer would demonstrate that a factor is 
unbiased or not discriminatory for the purposes of the comparative 
analyses and recommended narrowing the definition of ``factor'' to 
distinguish it from evidentiary standards, processes, and strategies, 
and instead use the term to describe the basis for the plan's or 
issuer's application of an NQTL. Another commenter recommended not 
including information that the plan or issuer considered but rejected 
in the definition of factors, because it is not illustrative of the 
ultimate value of the mental health or substance use disorder benefit 
or the plan's or issuer's compliance with MHPAEA's NQTL standards. The 
commenter stated that the actual design of the benefit and how it 
translates to payments, denials, and reimbursement should substantiate 
whether the benefit design complies with parity requirements, without 
examining extraneous information on considerations early in the 
benefit's development process. A commenter suggested the Departments 
include an example of what the Departments would consider a complete 
definition of a factor and information about how to specify the weight 
assigned to factors.
    The Departments are finalizing the definition of the term 
``factor'' as proposed. The definition and list of examples of factors 
in the definition contained in these final rules are sufficiently 
detailed to provide context to plans and issuers in identifying 
factors, including by distinguishing evidentiary standards from factors 
and acknowledging that factors other than processes and strategies, 
which are types of factors, may exist. Under the 2013 final 
regulations, plans and issuers were permitted to utilize a wide array 
of factors in designing and applying their NQTLs to mental health and 
substance use disorder benefits provided they were comparable to, and 
applied no more stringently than, those utilized to design and apply 
NQTLs to medical/surgical benefits. Similarly, the CAA, 2021 did not 
limit what factors plans and issuers could use to design and apply 
their NQTLs, but instead required that these factors be identified and 
analyzed in the comparative analyses.
    As noted in the preamble to the proposed rules, taking into account 
not only the factors that the plan or issuer relied upon, but also 
those that were considered but ultimately rejected in the definition of 
factors, is consistent with previous guidance on MHPAEA, namely because 
it is a factor that a plan or issuer uses in designing and applying an 
NQTL. The Departments recognize that the language used in the proposed 
rules, which included factors that were considered and rejected, rather 
than those that are relied upon and rejected, could be interpreted as 
including a broader set of information than prior guidance, which had 
interpreted ``considered'' to include ``factors that were relied upon 
and were rejected.'' The Departments did not intend to broaden the set 
of information included as a factor, and agree with the commenter who 
questioned the utility of providing information that was considered 
early in the design process but rejected. However, the Departments 
affirm that taking into account information that the plan or issuer 
relied upon and rejected in the definition of factors is necessary to 
analyze compliance with MHPAEA.
    In the proposed rules, the Departments proposed to define 
``processes'' and ``strategies'' as types of factors, and to clarify 
the differences between the two terms as they relate to the design and 
application of an NQTL. Specifically, the Departments proposed defining 
``processes'' as relating to the application of an NQTL, while 
``strategies'' would relate to the design of an NQTL. After review of 
the comments, the Departments continue to be of the view that the best 
read of the statutory text (as well as the 2013 final regulations) is 
that processes and strategies are types of factors, rather than 
components of a factor to be separately evaluated.
    The Departments proposed to define ``processes'' to mean actions, 
steps, or procedures that a plan or issuer uses to apply an NQTL, 
including actions, steps or procedures established by the plan or 
issuer as requirements in order for a participant or beneficiary to 
access benefits, including through actions by a participant's or 
beneficiary's authorized representative or a provider or facility. 
Under the proposed rules, processes include, but are not limited to: 
prior authorization procedures, provider referral requirements, and the 
development and approval of a treatment plan. The proposed definition 
also provided that processes include the specific procedures used by 
staff or other representatives of a plan or issuer (or the service 
provider of a plan or issuer) to administer the application of NQTLs, 
such as how a panel of staff members applies the NQTL (including the 
qualifications of staff involved, number of staff members allocated, 
and time allocated), consultations with panels of experts in applying 
the NQTL, and reviewer discretion in adhering to criteria hierarchy 
when applying an NQTL.
    A commenter expressed appreciation for the proposed rules' intent 
and requested the Departments to include more specific examples of 
``processes.'' Another commenter stated that the proposed definition 
for ``processes'' is too broad and focuses only on the end result of 
access to benefits, which the commenter stated is inconsistent with the 
Departments' previous guidance and regulations, and recommended 
narrowing the definition to focus on the operational application of any 
requirements.
    After reviewing comments, the Departments are finalizing the 
definition of the term ``processes,'' with minor changes so that the 
examples of processes more clearly illustrate the way the action, step, 
or procedure is used to apply an NQTL.\62\ While the Departments 
decline to add examples to the definition, these modifications will add 
clarity to the definition in these final rules.\63\ The Departments 
note that the final definition of the term does not focus only on the 
end result of access to benefits, but also includes the operational 
application of an NQTL, as evidenced by the framing of the definition 
in terms of actions, steps, or procedures used to apply an NQTL. For 
example, prior authorization processes include the procedures 
established by a plan or issuer for a review to determine how a 
specific request for prior authorization should be granted or denied. 
Concurrent review processes include the procedures established by a 
plan or issuer for a review to determine whether a specific request 
should be

[[Page 77597]]

granted or denied, such as when peer-to-peer review is required.
---------------------------------------------------------------------------

    \62\ The Departments are also finalizing a non-substantive 
modification so that the definition more closely parallels the 
definition of ``strategies.''
    \63\ For example, these final rules clarify that provider 
referral requirements are processes if they are used to determine 
when and how a participant or beneficiary may access certain 
services. Similarly, the development and approval of a treatment 
plan are processes if they are used in a concurrent review process 
to determine whether a specific request should be granted or denied.
---------------------------------------------------------------------------

    The proposed rules proposed to define ``strategies'' as practices, 
methods, or internal metrics that a plan or issuer considers, reviews, 
or uses to design an NQTL, and included examples of strategies. The 
proposed definition of strategies included the following examples: the 
development of the clinical rationale used in approving or denying 
benefits; deviation from generally accepted standards of care; the 
selection of information (such as from medical or clinical guidelines) 
deemed reasonably necessary to make a medical necessity determination; 
reliance on treatment guidelines or guidelines provided by third-party 
organizations; and rationales used in selecting and adopting certain 
threshold amounts, professional protocols, and fee schedules. The 
proposed definition of strategies also specifically included: the 
creation and composition of the staff or other representatives of a 
plan or issuer (or the service provider of a plan or issuer) that 
deliberates, or otherwise makes decisions, on the design of NQTLs, 
including the plan's or issuer's decisions related to qualifications of 
staff involved; number of staff members allocated, and time allocated; 
breadth of sources and evidence considered; consultations with panels 
of experts in designing the NQTL; and the composition of the panels 
used to design an NQTL.
    One commenter supported the inclusion in the definition of 
``strategies'' of practices that involve ``deviations from generally 
accepted standards of care.'' Several commenters also recommended that 
the Departments include actions to detect or prevent and prove fraud, 
waste, and abuse in the definitions of either or both ``processes'' and 
``strategies,'' rather than including those actions as a stand-alone 
exception from the NQTL requirements in the final rules. Another 
commenter appreciated the clear distinction made in the proposed 
definitions of processes and strategies and stated that they would 
appreciate if these distinctions tracked with separate steps in the 
comparative analyses.\64\
---------------------------------------------------------------------------

    \64\ The content elements of comparative analyses are addressed 
later in this preamble.
---------------------------------------------------------------------------

    The Departments are generally finalizing the definition of the term 
``strategies'' with some minor changes to the examples to add 
specificity. The definition of the term ``strategies'' in these final 
rules includes examples of strategies used to design an NQTL, such as 
the method of determining whether and how to deviate from generally 
accepted standards of care in concurrent reviews; rationales used in 
selecting and adopting certain threshold amounts to apply an NQTL; 
professional standards and protocols to determine utilization 
management standards; and fee schedules used to determine provider 
reimbursement rates, used as part of an NQTL. The Departments note 
that, once a plan or issuer uses a strategy to design an NQTL, that 
design also may result in the establishment or use of processes to 
apply the NQTL.
    While the Departments acknowledge comments suggesting that actions 
to detect or prevent and prove fraud, waste, and abuse be defined as 
either ``processes'' or ``strategies,'' and acknowledge that such 
actions certainly could constitute either processes or strategies 
(depending on whether the action is undertaken to design or apply the 
NQTL), the Departments decline to add a specific reference to actions 
to detect or prevent and prove fraud, waste, and abuse to the relevant 
definitions, as the proposed exception for standards to detect or 
prevent and prove fraud, waste, and abuse is not being finalized, as 
discussed later in this preamble.\65\ However, the Departments are 
providing additional language to explain what constitutes a standard to 
detect or prevent and prove fraud and abuse (also referred to as 
``fraud and abuse measures'') later in this preamble and how such 
standards must comply with MHPAEA under these final rules.
---------------------------------------------------------------------------

    \65\ The proposed rules referred to fraud, waste, and abuse. 
However, as explained later in this preamble, the Departments agree 
with commenters that the term ``waste'' can be construed in a manner 
that is overly broad. Thus, in these final rules, when discussing 
the exception in the proposed rules for NQTLs that are narrowly and 
reasonably designed to detect or prevent and prove fraud, waste, and 
abuse, while minimizing the impact on access to appropriate mental 
health and substance use disorder benefits, this preamble refers to 
``fraud, waste, and abuse measures.'' When discussing provisions of 
this final rule related to carefully circumscribed measures 
reasonably and appropriately designed to detect or prevent and prove 
fraud and abuse, this preamble refers to ``fraud and abuse 
measures.''
---------------------------------------------------------------------------

c. Treatment Limitations
    The Departments proposed to amend the definition of ``treatment 
limitations'' to clarify that the illustrative list of NQTLs to which 
the definition refers is non-exhaustive and to amend the last sentence 
to state that a ``complete'' (rather than ``permanent'') exclusion of 
all benefits for a particular condition or disorder is not a treatment 
limitation for purposes of the definition. In the preamble to the 
proposed rules, the Departments noted that, while NQTLs are generally 
defined as treatment limitations that are not expressed numerically, 
the application of an NQTL in a numerical way does not modify its 
nonquantitative character simply because the NQTL sometimes involves 
numerical standards, and such NQTLs would still be evaluated in 
accordance with the rules for NQTLs under the statute and implementing 
regulations.
    Several commenters supported the Departments' amendment to the 
definition of ``treatment limitation'' to specify that ``a complete 
exclusion of all benefits for a particular condition or disorder is not 
a treatment limitation for purposes of this definition,'' rather than 
retaining the reference in the 2013 final regulations to a 
``permanent'' exclusion. These commenters stated that the proposed 
definition more clearly specifies that a plan or issuer can exclude a 
particular condition or service without creating an NQTL, but that in 
doing so, the exclusion must be total. The commenters suggested the 
Departments include specific examples of permissible exclusions and 
impermissible exclusionary language. Other commenters expressed concern 
that the proposed definition of ``treatment limitation'' is too broad 
and argued that the proposed definition would lead to increased 
uncertainty in determining which common plan practices could constitute 
an NQTL. One commenter stated that if there is no comparable medical or 
surgical treatment limitation, there is nothing to compare a treatment 
limitation on a mental health or substance use disorder benefit to, and 
that therefore such a limitation on the mental health or substance use 
disorder benefit is not subject to parity requirements. Several 
commenters recommended adopting a consistent and exhaustive definition 
for determining whether a medical management technique is a treatment 
limitation.
    The Departments are finalizing the definition of ``treatment 
limitation'' as proposed, with minor modifications to add an example of 
an NQTL. As reflected in the definition, medical management techniques 
are NQTLs if they limit the scope or duration of treatment. While the 
definition as amended is broad, plans and issuers have great latitude 
in the types of limitations that they may impose, and the Departments 
understand that plans and issuers do in fact impose a broad range of 
limitations on the scope or duration of treatment. In enacting MHPAEA 
and the amendments to MHPAEA contained in the CAA, 2021, Congress did 
not prohibit the use of these limitations for mental health and 
substance use disorder benefits, but

[[Page 77598]]

required that plans and issuers ensure that NQTLs satisfy the statutory 
requirements that (1) any treatment limitations imposed on mental 
health and substance use disorder benefits are no more restrictive than 
the predominant treatment limitations imposed on substantially all 
medical/surgical benefits; (2) that no treatment limitations be imposed 
only with respect to mental health and substance use disorder benefits; 
and (3) that plans and issuers perform and document comparative 
analyses of the design and application of NQTLs. Because of the broad 
range of treatment limitations that plans and issuers may impose, 
combined with the freedom that plans and issuers have to design their 
own unique limitations, the Departments cannot provide a comprehensive 
and exhaustive list of all limitations, as further explained later in 
this preamble.
    The Departments note that if a plan or issuer applies a treatment 
limitation to mental health and substance use disorder benefits where 
medical/surgical benefits are not subject to a comparable treatment 
limitation in the same classification, the plan or issuer would violate 
MHPAEA because it must not apply separate treatment limitations only to 
mental health and substance use disorder benefits. Further, the 
Departments have stated that, if a plan or issuer provides any benefits 
for a mental health condition or substance use disorder but excludes 
benefits for items or services for that condition or disorder in a 
classification in which it provides medical/surgical benefits, such an 
exclusion of a benefit for a condition or disorder that is otherwise 
covered is a treatment limitation because it is a limit on the scope or 
duration of treatment offered.\66\ While the Departments decline to 
provide additional examples of permissible exclusions and impermissible 
exclusionary language in these final rules, examples of such exclusions 
and language have been provided in guidance and in the Departments' 
reports to Congress.

3. Nonquantitative Treatment Limitations--26 CFR 54.9812-1(c)(4), 29 
CFR 2590.712(c)(4), and 45 CFR 146.136(c)(4)
    In the proposed rules, the Departments proposed changes designed to 
better ensure that plans and issuers do not design and implement NQTLs 
that impose greater restrictions on access to mental health and 
substance use disorder benefits as compared to medical/surgical 
benefits. The Departments proposed to add requirements that apply to 
NQTLs with respect to mental health and substance use disorder 
benefits, to ensure that plans and issuers do not impose a greater 
burden on participants and beneficiaries accessing those benefits than 
the burden imposed on participants and beneficiaries accessing medical/
surgical benefits, while preserving the ability of plans and issuers to 
impose NQTLs to the extent they are consistent with generally 
recognized independent professional medical or clinical standards or 
legitimate and narrowly designed standards related to fraud, waste, and 
abuse. Subject to those two narrow exceptions for those types of NQTLs, 
the proposed rules provided that plans and issuers would not be 
permitted to impose an NQTL on mental health or substance use disorder 
benefits unless they satisfied all of the following three requirements: 
(1) the NQTL is no more restrictive as applied to mental health and 
substance use disorder benefits than to medical/surgical benefits (also 
referred to as the no more restrictive requirement); (2) the plan or 
issuer satisfies requirements related to the design and application of 
the NQTL (also referred to as the design and application requirements); 
and (3) the plan or issuer collects, evaluates, and considers the 
impact of relevant data on access to mental health and substance use 
disorder benefits relative to access to medical/surgical benefits; and 
subsequently takes reasonable action, as necessary, to address any 
material differences in access shown in the data to ensure compliance 
with MHPAEA (also referred to as the relevant data evaluation 
requirements).
    Specifically, under the no more restrictive requirement, the 
proposed rules specified that a plan or issuer may not apply any NQTL 
to mental health or substance use disorder benefits in any 
classification that is more restrictive, as written or in operation, 
than the predominant NQTL that applies to substantially all medical/
surgical benefits in the same classification. This requirement was 
intended to ensure that the implementing regulations more closely 
mirrored the statutory language in Code section 9812(a)(3)(A), ERISA 
section 712(a)(3)(A), and PHS Act section 2726(a)(3)(A).
    The proposed rules outlined a four-prong test for a plan or issuer 
to determine compliance with the no more restrictive requirement. 
Specifically, this provision would have required plans and issuers to 
determine: (1) the portion of plan payments for medical/surgical 
benefits subject to an NQTL in a classification; (2) whether the NQTL 
applies to substantially all medical/surgical benefits in the 
classification; (3) if the NQTL applies to substantially all medical/
surgical benefits in the classification, the predominant variation of 
the NQTL that applies to substantially all medical/surgical benefits in 
the classification; and (4) whether the NQTL, as applied to mental 
health and substance use disorder benefits in the classification, is 
more restrictive than the predominant variation of the NQTL as applied 
to substantially all medical/surgical benefits.
    The second proposed requirement for NQTLs, the design and 
application requirements, retained the requirements for NQTLs from the 
2013 final regulations focused on the processes, strategies, 
evidentiary standards, and other factors used to apply an NQTL, with a 
proposed modification to better align the rules with the statute's 
focus on the design of an NQTL in addition to its application. In 
addition, the Departments proposed to prohibit plans and issuers from 
relying upon any factor or evidentiary standard if the information, 
evidence, sources, or standards on which the factor or evidentiary 
standard was based discriminates against mental health or substance use 
disorder benefits as compared to medical/surgical benefits.
    The third requirement for NQTLs under the proposed rules, the 
relevant data evaluation requirements, proposed to require plans and 
issuers to collect and evaluate relevant outcomes data and take 
reasonable action to address material differences in access between 
mental health and substance use disorder benefits and medical/surgical 
benefits as necessary to ensure compliance, in operation, with MHPAEA. 
This requirement also included a proposed special rule for NQTLs 
related to network composition.
    The proposed rules stated that, if a plan or issuer fails to meet 
any of the three requirements under the proposed rules with respect to 
an NQTL in a classification, the NQTL would violate MHPAEA and, as a 
result, could not be imposed on mental health or substance use disorder 
benefits in the classification without changes to the terms of the plan 
or coverage, or the way the NQTL is designed or applied, to ensure 
compliance with MHPAEA.
    The Departments proposed two limited exceptions to some of the 
requirements for NQTLs, consistent with the Departments' intention to 
avoid interference with a plan's or issuer's attempts to ensure that 
NQTLs imposed with respect to benefits for

[[Page 77599]]

treatment of mental health conditions or substance use disorders are 
consistent with generally accepted independent professional medical or 
clinical standards of care (also referred to as independent 
professional medical or clinical standards) or are narrowly and 
reasonably designed to detect or prevent and prove fraud, waste, and 
abuse, while minimizing the impact on access to appropriate mental 
health and substance use disorder benefits (also referred to as fraud, 
waste, and abuse measures). The Departments proposed to exempt NQTLs 
qualifying for the exception for independent professional medical or 
clinical standards from compliance with the no more restrictive 
requirement, the prohibition on discriminatory factors and evidentiary 
standards, and the relevant data evaluation requirements. The 
Departments proposed to exempt NQTLs qualifying for the exception for 
fraud, waste, and abuse measures from compliance with the no more 
restrictive requirement and the prohibition on discriminatory factors 
and evidentiary standards, but not the relevant data evaluation 
requirements.
    Finally, the Departments proposed to make clear that a plan or 
issuer that has received a final determination of noncompliance under 
the comparative analysis review process established by the CAA, 2021, 
including a final determination of noncompliance based on failure to 
provide a sufficient comparative analysis, would also be in violation 
of the substantive requirements that apply to NQTLs under MHPAEA, as 
determined by the Departments. Upon such a determination, the proposed 
rules would permit the Departments to direct the plan or issuer to not 
impose the NQTL that is the subject of the comparative analysis, unless 
and until the plan or issuer can demonstrate compliance or take 
appropriate action to remedy the violation.
    The Departments requested comments on all aspects of these proposed 
amendments, including the exceptions to the proposed rules regarding 
NQTLs. Many commenters expressed support for these provisions of the 
proposed rules as a whole, as a means of achieving increased access to 
mental health and substance use disorder benefits by targeting NQTLs 
that otherwise impede access. Other commenters expressed support for 
the proposed rules' enhanced specificity with respect to the 
requirements for imposing NQTLs, with one commenter also indicating 
that the proposals would help State insurance regulators better enforce 
MHPAEA and clarify plans' and issuers' compliance obligations.
    However, other commenters expressed the view that these provisions 
of the proposed rules were complex, ambiguous, confusing, subject to 
interpretation, or difficult to operationalize, which they argued could 
lead to substantial uncertainty for plans and issuers attempting to 
comply. Commenters also stated that it may be impossible for plans or 
issuers to meet the proposed mathematical substantially all and 
predominant tests as applied to NQTLs, leading them to eliminate 
necessary utilization management tools. Some commenters also indicated 
that these provisions of the proposed rules could lead to inconsistent 
application of NQTLs across plans administered by the same TPA or 
issuer, which could result in administrative complexity and cause 
confusion for consumers and providers. Other commenters highlighted 
that the proposed requirements would significantly increase the cost of 
administering plans and health insurance coverage. One commenter 
indicated that some plans might consider excluding all treatments or 
services for a particular mental health condition or substance use 
disorder as a result of the additional burdens imposed by the 
substantially all and predominant tests, if finalized as proposed. Some 
commenters also stated that the additional proposed requirements for 
NQTLs do not add value beyond distinctions already captured by the 
design and application requirements included in the 2013 final 
regulations, with some commenters stating those additional requirements 
go beyond MHPAEA's statutory requirements. Comments specific to each of 
the three requirements and two exceptions proposed at 26 CFR 54.9812-
1(c)(4)(i), (ii), and (iv); 29 CFR 2590.712(c)(4)(i), (ii), and (iv); 
and 45 CFR 146.136(c)(4)(i), (ii), and (iv) are discussed in greater 
detail later in this preamble.
    The Departments acknowledge the concerns expressed by commenters 
and, in response to comments, the Departments are finalizing a modified 
framework that is still intended to prevent plans and issuers from 
designing and applying NQTLs that impose greater burdens on access to 
mental health and substance use disorder benefits as compared to 
medical/surgical benefits, while limiting uncertainty, increases in 
cost, operational difficulty, and unintended consequences. These final 
rules streamline the proposed rules' general requirements to eliminate 
redundancies and add clarity for plans and issuers in a manner that 
remains consistent with the statutory text of MHPAEA, while also 
ensuring participants and beneficiaries will not face greater 
restrictions on access to mental health and substance use disorder 
benefits as compared to medical/surgical benefits.
    These final rules do not finalize the language of the proposed ``no 
more restrictive'' requirement, as discussed in more detail later in 
this preamble, and instead incorporate the statutory requirements of 
Code section 9812(a)(3)(A), ERISA section 712(a)(3)(A), and PHS Act 
section 2726(a)(3)(A) as the overall general rule for NQTLs in 26 CFR 
54.9812-1(c)(4), 29 CFR 2590.712(c)(4), and 45 CFR 146.136(c)(4). 
Specifically, these final rules state that, consistent with the 
fundamental purpose of MHPAEA, a group health plan (or health insurance 
coverage offered by an issuer in connection with a group health plan) 
may not impose any NQTL with respect to mental health or substance use 
disorder benefits in any classification that is more restrictive, as 
written or in operation, than the predominant NQTL that applies to 
substantially all medical/surgical benefits in the same classification. 
However, as discussed later in this preamble, the Departments are 
declining to finalize the proposed four-prong test for the no more 
restrictive requirement, which was proposed to determine compliance 
with statutory requirements as they apply to NQTLs.\67\ Rather, to 
demonstrate compliance with the no more restrictive requirement, which 
is now the general rule for NQTLs, a plan or issuer is required under 
these final rules to satisfy (1) the design and application 
requirements and (2) the relevant data evaluation requirements, each of 
which the Departments are finalizing with modifications, as discussed 
in more detail later in this preamble. Additionally, the Departments 
are not finalizing the exceptions set forth in the proposed rules, but 
have added language to these final rules to explain how plans and 
issuers should analyze and account for independent professional medical 
or clinical standards and fraud and abuse measures in designing and 
applying their NQTLs. Finally, the Departments are finalizing a 
provision providing that, depending on the relevant facts and 
circumstances, the Departments or an applicable State authority may 
direct a plan or issuer that has received a final determination of 
noncompliance under the comparative analysis review process

[[Page 77600]]

established by the CAA, 2021 to not apply an impermissible NQTL.

a. Requirement That NQTLs Be No More Restrictive for Mental Health 
Benefits and Substance Use Disorder Benefits--26 CFR 54.9812-1(c)(4), 
29 CFR 2590.712(c)(4), and 45 CFR 146.136(c)(4)
    Through the proposed mathematical substantially all and predominant 
tests for NQTLs as part of the no more restrictive requirement, the 
Departments proposed to require plans and issuers to follow similar 
steps to those that apply when analyzing parity with respect to 
financial requirements or quantitative treatment limitations under the 
2013 final regulations (referred to in this preamble as the proposed 
mathematical substantially all and predominant tests). As noted in the 
proposed rules, the steps in the proposed mathematical substantially 
all and predominant tests would have involved determining the portion 
of plan payments for medical/surgical benefits subject to an NQTL in a 
classification; whether the NQTL applies to substantially all medical/
surgical benefits in the classification; if the NQTL applies to 
substantially all medical/surgical benefits in the classification, the 
predominant variation of the NQTL that applies to substantially all 
medical/surgical benefits in the classification; and whether the NQTL, 
as applied to mental health and substance use disorder benefits in the 
classification, is more restrictive than the predominant variation of 
the NQTL, as applied to substantially all medical/surgical benefits.
    Many commenters generally supported application of the proposed 
mathematical substantially all and predominant tests to NQTLs, with 
some indicating that the tests would provide additional clarity, 
eliminate subjectivity, assist regulators, and result in compliance 
improvements. Many of these commenters also stated that the statute 
clearly supports the tests, as it requires treatment limitations to be 
``no more restrictive'' than the predominant treatment limitations that 
apply to substantially all medical/surgical benefits. Other commenters 
generally opposed the inclusion of the substantially all and 
predominant tests for NQTLs as part of the no more restrictive 
requirement. Some of these commenters stated that the proposed 
mathematical substantially all and predominant tests are a reversal of 
policy from the 2013 final regulations and are inconsistent with 
congressional intent, because Congress codified the design and 
application requirements from the 2013 final regulations in the CAA, 
2021. These commenters highlighted that the Departments had stated 
previously that they understood NQTLs could not be easily quantified 
and that the Departments had not sufficiently explained their change in 
interpretation under the proposed rules.
    Some commenters expressed general concerns that NQTLs are 
inherently unquantifiable, arguing that the proposal would result in 
unworkable standards or arbitrary outcomes that could prohibit plans 
and issuers from using evidence-based medical guidelines or other 
relevant factors specific to the item or service under consideration. 
Commenters also raised concerns that imposition of the proposed 
mathematical substantially all and predominant tests on certain types 
of NQTLs that are not commonly utilized for medical/surgical benefits 
may lead to some types of legitimate NQTLs no longer being permitted 
with respect to mental health and substance use disorder benefits. 
Specifically, several of these commenters contended that the proposed 
mathematical substantially all and predominant tests, as proposed, 
would result in the elimination of plans' and issuers' ability to 
impose certain NQTLs with respect to mental health and substance use 
disorder benefits, such as step therapy, prior authorization, and 
concurrent review, which they posited would negatively impact the 
quality and cost of care. Some commenters also cited potential 
negative, unintended consequences of the application of the proposed 
mathematical substantially all and predominant tests, as proposed, 
including patient safety concerns; impacts on health outcomes, quality, 
and affordability; and a chilling effect on access improvements and 
innovation. Further, some commenters expressed concern with the 
increased costs associated with complying with the proposed 
mathematical substantially all and predominant tests, with some stating 
that this increased burden would not be offset by any resulting 
increase in access to mental health and substance use disorder benefits 
for participants and beneficiaries.
    Several commenters expressed confusion as to how these tests, as 
proposed, would be applied in practice and highlighted the need for 
more detail. Specifically, some commenters stated that these proposed 
provisions lack clarity in how the tests apply to certain types of 
NQTLs (including those related to network composition), and the 
potential consequences of enforcement of these requirements. Many 
commenters provided specific comments and feedback on aspects of each 
part of the substantially all and predominant tests included in the 
proposed rules, as discussed later in this preamble, and highlighted 
ambiguities and challenges operationalizing the proposed quantitative 
testing requirements with respect to NQTLs.
    Under the first prong of the proposed mathematical substantially 
all and predominant tests, plans and issuers would have been required 
to determine the portion of plan payments for medical/surgical benefits 
in the classification expected to be subject to the NQTL based on the 
dollar amount of all plan payments for medical/surgical benefits in the 
classification expected to be paid under the plan or coverage for the 
plan year (or the portion of the plan year after a change in benefits 
that affects the applicability of the NQTL). The proposed rules stated 
that, for purposes of this determination, any reasonable method could 
be used to determine the dollar amount expected to be paid under a plan 
for medical/surgical benefits.
    The Departments received many comments on the proposed requirement 
that the plan or issuer determine the portion of plan payments for 
medical/surgical benefits expected to be subject to an NQTL in the 
benefit classification. Several commenters indicated that the 
determination of the dollar amount of all plan payments for medical/
surgical benefits expected to be paid may be an inappropriate measure 
altogether because NQTLs like medical management, assessments related 
to medical necessity, experimental/investigational treatment 
exclusions, prior authorization requests, and provider network 
admission standards are not generally attached to claims. Some 
commenters highlighted that self-insured plan sponsors may face 
challenges in obtaining a complete and reliable set of plan-level 
claims data, and accordingly, would have limited data to use to assess 
individual NQTLs, or would incur additional costs.
    After determining the portion of plan payments for medical/surgical 
benefits in the classification expected to be subject to the NQTL, the 
Departments proposed that, under the second prong, plans and issuers 
would be required to determine whether the NQTL applies to 
substantially all medical/surgical benefits in the classification, 
based on the dollar amount of all plan payments for medical/surgical 
benefits in the classification expected to be paid under the plan for 
the plan year. Under the proposed rules, an NQTL would be considered to 
apply to substantially all medical/surgical benefits in a

[[Page 77601]]

classification if it applies to at least two-thirds of all medical/
surgical benefits in that classification. Under the proposed rules, 
whether the NQTL applies to at least two-thirds of all medical/surgical 
benefits would be determined without regard to whether the NQTL was 
triggered based on a particular factor or evidentiary standard.\68\ The 
proposed rules further provided that if an NQTL does not apply to at 
least two-thirds of all medical/surgical benefits in a classification, 
that NQTL would not be permitted to be applied to mental health or 
substance use disorder benefits in that classification.
---------------------------------------------------------------------------

    \68\ For example, if a plan or issuer applies a general 
exclusion for all benefits in a classification that are for 
experimental or investigative treatment, and defines experimental or 
investigative treatment to be treatments with less than a certain 
number of peer-reviewed studies demonstrating efficacy, under the 
proposed rules, the exclusion would be treated as applying to all of 
the benefits in the classification--not just those that may be 
subject to the general exclusion for experimental or investigative 
treatment because they lack the requisite number of peer-reviewed 
studies (that is, those that actually triggered the NQTL based on 
the evidentiary standard). 88 FR 51552, 51570 (Aug. 3, 2023).
---------------------------------------------------------------------------

    The Departments received many comments regarding this prong of the 
proposed mathematical substantially all and predominant tests. As 
mentioned earlier in this preamble, many commenters stated that, in 
practice, a numerical ``substantially all'' determination would be 
difficult to apply and assess for NQTLs for many reasons, including 
because they are often not quantifiable, and there are more medical/
surgical items and services (and associated benefits) than there are 
mental health and substance use disorder items and services. 
Additionally, commenters highlighted that plans and issuers already 
experience difficulty in obtaining data from service providers and 
would have difficulty in determining which NQTLs apply to at least two-
thirds of medical/surgical benefits in a classification. Some 
commenters predicted that, if the Departments finalize the 
substantially all and predominant tests as proposed, plans and issuers 
might increase the application of NQTLs to medical/surgical benefits to 
meet the two-thirds threshold.
    Further, some commenters requested that the Departments specify and 
provide examples showing how to apply the substantially all test to 
NQTLs that are not associated with plan payments, such as prescription 
drug formularies and network composition standards. One commenter 
highlighted that it is difficult to calculate the amount of plan 
payments expected to be paid for prescription drugs subject to an NQTL. 
Another commenter urged the Departments to clarify the determination of 
whether an NQTL applies regardless of whether the NQTL was triggered. 
For example, this commenter highlighted that insurers might state that 
prior authorization ``applies'' to all benefits in a classification 
where a benefit is considered or evaluated under the various factors 
for determining whether to apply prior authorization, even if the 
benefit ultimately is determined to not be subject to prior 
authorization based on the application of factors and evidentiary 
standards.
    In addition, in the proposed rules, the Departments solicited 
comments on whether plans and issuers maintain systems capable of 
determining, under the proposed mathematical substantially all and 
predominant tests, whether an NQTL applies to substantially all 
medical/surgical benefits in a classification, and the administrative 
burden that would be associated with such determinations. Several 
commenters highlighted that it would be difficult to comply with the 
substantially all and predominant tests as proposed, including because 
the requisite data may be housed in different parts of a plan's or 
issuer's organization. One commenter emphasized that current 
administrative systems would need to be adapted, and plans and issuers 
would need to hire additional staff or service providers to be able to 
perform the analysis that would be required under the proposed 
mathematical substantially all and predominant tests.
    Under the proposed rules, if a plan or issuer determined that an 
NQTL applies to substantially all medical/surgical benefits in a 
classification, the third prong of the test would require a plan or 
issuer to determine the predominant variation of the NQTL that is 
applied to substantially all medical/surgical benefits subject to the 
NQTL in the classification. The Departments proposed that the term 
``predominant'' would, for this purpose, mean the most common or most 
frequent variation of an NQTL within a benefit classification.
    The Departments received many comments regarding this part of the 
proposed tests. Numerous commenters stated that this aspect of the 
substantially all and predominant tests is unworkable. Some commenters 
noted that, with a lack of guidance on how to identify all the 
variations of a particular NQTL (especially those that are complex and 
nuanced), the proposed rules may not be feasible for plans, issuers, 
and regulators to apply in real-life situations. Several commenters 
stated that, while financial requirements and quantitative treatment 
limitations will have only a few different variations, NQTLs are 
multifactorial and each difference could be considered a different 
variation, or even a separate NQTL. For example, some of these 
commenters highlighted that prior authorization or concurrent review 
may take varied forms: an admission that requires advance prior 
authorization; an admission that requires notification but no clinical 
review; a nonclinical review based on predetermined standards; a first-
level or nurse clinical review; a second-level or physician clinical 
review; and a peer-to-peer clinical review. These commenters noted that 
some processes may be automated or manual, some may be handled by 
vendors or directly by the plan or issuer, and some may have multiple 
utilization management systems within all of the aforementioned 
categories. Another commenter highlighted that a plan or regulator 
could conceivably determine that ``variations'' include a wide range of 
aspects, such as the credentials of the reviewer, the type or source of 
clinical criteria applied, the timing of the review (for example, 
urgent vs. nonurgent), the modality of authorization submission (for 
example, via electronic health record vs. fax or pdf form), among 
others. As a result, these commenters stated that determining how to 
identify the predominant variation of an NQTL may not be feasible 
without additional clarifications. Many commenters requested that the 
Departments provide a definition of the term ``variation'' and an 
explanation of how to determine whether a variation exists, as well as 
additional guidance and examples illustrating when an NQTL has no 
variation and when an NQTL has multiple variations (beyond variations 
based on numerical distinctions). These commenters also noted that, 
under the proposed rules, the predominant variation may only apply to a 
small percentage of medical/surgical services or items in the 
applicable benefit classification.
    Lastly, under the fourth prong, the proposed rules provided that an 
NQTL applied to mental health or substance use disorder benefits cannot 
be more restrictive than the predominant variation of the NQTL applied 
to substantially all medical/surgical benefits in the same 
classification. Under the proposed rules, for this purpose, an NQTL 
would be considered restrictive if it imposes conditions, terms, or 
requirements that limit access to benefits under the terms of the plan 
or coverage. For this purpose,

[[Page 77602]]

conditions, terms, or requirements would include, but not be limited 
to, those that compel an action by or on behalf of a participant or 
beneficiary to access benefits or limit access to the full range of 
treatment options available for a condition or disorder under the plan. 
As discussed later in this preamble, the Departments also proposed that 
an NQTL applied to mental health or substance use disorder benefits in 
any classification would not be considered to violate the no more 
restrictive requirement if the NQTL impartially applies independent 
professional medical or clinical standards or fraud, waste, and abuse 
measures, that meet specific requirements.
    Some commenters supported this approach to the ``more restrictive'' 
part of the test in the proposed rules because, according to these 
commenters, it provided a more concrete and less subjective standard. 
Other commenters emphasized, as discussed earlier in this preamble, 
that the proposed mathematical substantially all and predominant tests, 
which provide a quantitative basis for comparison, are unworkable for 
NQTLs and administratively burdensome. Many of these commenters 
requested that, if the proposed mathematical substantially all and 
predominant tests are finalized, the Departments provide extensive and 
detailed implementation guidance to assist plans and issuers in 
complying with what the commenters characterized as this challenging 
framework. Another commenter suggested that the Departments establish a 
safe harbor for plans and issuers from the substantially all and 
predominant tests for any variation in NQTL outcomes data driven by 
State law or regulation.
    The Departments appreciate the detailed comments received on all 
aspects of the proposed mathematical substantially all and predominant 
tests, including comments particular to each aspect of the proposed 
four-prong test. The Departments acknowledge that many commenters 
expressed concerns that applying to NQTLs the same proposed 
mathematical substantially all and predominant tests that are 
applicable to financial requirements or quantitative treatment 
limitations may be difficult to operationalize and could be unworkable. 
The Departments acknowledge that this framework was first developed for 
financial requirements and quantitative treatment limitations, where 
there are relatively clear and limited numbers of variations, and that 
the framework might be impractical or impossible for NQTLs, which 
differ in how they are designed and applied to various benefits.
    At the same time, the Departments agree with commenters who stated 
that applying the statutory no more restrictive requirement to NQTLs 
under the proposed rules would assist regulators tasked with enforcing 
MHPAEA's requirements and result in overall compliance improvements by 
formalizing and providing greater clarity on what plans and issuers 
must do to comply with MHPAEA. The Departments also agree with 
commenters who emphasized the importance of the statutory requirement 
that plans and issuers shall ensure that the treatment limitations they 
impose on mental health and substance use disorder benefits generally 
are no more restrictive than those they impose on medical/surgical 
benefits. The proposed rules made clear that the incorporation of this 
statutory language into regulations is key to ensuring that people 
seeking mental health and substance use disorder treatment do not face 
a greater burden on access to benefits for such treatment than on 
access to benefits for medical treatment and surgical procedures, a 
premise that is central to MHPAEA.
    After reviewing all the comments on the proposed four prongs of the 
no more restrictive requirement, the Departments have sought to address 
many of the workability concerns expressed by commenters, while 
honoring statutory requirements. Specifically, due to concerns raised 
by the commenters, the Departments are declining to finalize the 
proposed mathematical substantially all and predominant tests for 
NQTLs, which would have based these determinations on the dollar amount 
of all plan payments for medical/surgical benefits expected to be paid, 
similar to the steps that apply when analyzing parity with respect to 
financial requirements or quantitative treatment limitations under the 
2013 final regulations. These final rules address commenters' 
operability and feasibility concerns with respect to the proposed 
mathematical substantially all and predominant tests, while continuing 
to set forth a standard for parity compliance that is grounded in 
MHPAEA's statutory text and is also sufficiently flexible to account 
for the unique and nonquantifiable nature of NQTLs. As noted later in 
this preamble, these final rules retain the focus on the design and 
application of NQTLs, including with respect to relevant outcomes 
measures, to ensure that NQTLs are no more restrictive in the context 
of mental health and substance use disorder benefits than in the 
context of medical/surgical benefits.
    Therefore, these final rules do not finalize the provisions 
proposed under 26 CFR 54.9812-1(c)(4)(i)(A) through (E), 29 CFR 
2590.712(c)(4)(i)(A) through (E), and 45 CFR 146.136(c)(4)(i)(A) 
through (E). Instead, consistent with MHPAEA's express statutory 
requirement,\69\ the Departments are finalizing under 26 CFR 54.9812-
1(c)(4), 29 CFR 2590.712(c)(4), and 45 CFR 146.136(c)(4) the general 
rule that, consistent with the fundamental purpose of MHPAEA, a group 
health plan (or health insurance coverage offered by an issuer in 
connection with a group health plan) may not impose any NQTL with 
respect to mental health or substance use disorder benefits in any 
classification that is more restrictive, as written or in operation, 
than the predominant NQTL that applies to substantially all medical/
surgical benefits in the same classification. Through this requirement, 
the Departments reiterate the importance of promoting the goals of the 
statute and ensuring that individuals have access to the mental health 
and substance use disorder benefits under their plan or coverage in a 
way that is not more restrictive than their access to the medical/
surgical benefits under their health coverage. For this purpose, 
consistent with the fundamental purpose of MHPAEA, an NQTL is more 
restrictive than the predominant NQTL that applies to substantially all 
medical/surgical benefits in the same classification if the plan or 
issuer fails to satisfy the design and application requirements at 26 
CFR 54.9812-1(c)(4)(i), 29 CFR 2590.712(c)(4)(i), and 45 CFR 
146.136(c)(4)(i) or the relevant data evaluation requirements at 26 CFR 
54.9812-1(c)(4)(iii), 29 CFR 2590.712(c)(4)(iii), and 45 CFR 
146.136(c)(4)(iii). Accordingly, plans and issuers must ensure that the 
processes, strategies, evidentiary standards, and other factors used to 
design and apply an NQTL to mental health or substance use disorder 
benefits are comparable to, and applied no more stringently than, the 
processes, strategies, evidentiary standards, and other factors used to 
design and apply the NQTL for medical/surgical benefits, including by 
ensuring that the information, evidence, sources, or standards on which 
factors and evidentiary standards are based are not biased and are 
objective. Additionally, plans and issuers must comply with the 
relevant data evaluation requirements,

[[Page 77603]]

including by collecting and evaluating relevant data, determining 
whether the data suggest an NQTL contributes to material differences in 
relevant outcomes related to access to mental health and substance use 
disorder benefits as compared to medical/surgical benefits, and if 
material differences in relevant outcomes related to access exist, 
taking reasonable action, as necessary, to address the material 
differences to ensure compliance, in operation, with 26 CFR 54.9812-
1(c)(4), 29 CFR 2590.712(c)(4), and 45 CFR 146.136(c)(4). Absent 
compliance with both the design and application requirements and the 
relevant data evaluation requirements with respect to an NQTL, which 
are addressed in more detail later in this preamble, a plan or issuer 
fails to comply with Code section 9812(a)(3)(A)(ii), ERISA section 
712(a)(3)(A)(ii), and PHS Act section 2726(a)(3)(A)(ii), as applicable, 
and may not impose the NQTL with respect to mental health or substance 
use disorder benefits. These requirements, taken together, require a 
plan to consider and evaluate an NQTL's design, application, and 
resulting outcomes to ensure that an NQTL is not more restrictive, as 
written or in operation, than the predominant NQTL that applies to 
substantially all medical/surgical benefits in the same classification.
---------------------------------------------------------------------------

    \69\ Code section 9812(a)(3)(A), ERISA section 712(a)(3)(A), and 
PHS Act section 2726(a)(3)(A).
---------------------------------------------------------------------------

    These final rules also include a few technical changes to this 
language, including relocation of the reference to 26 CFR 54.9812-
1(a)(1), 29 CFR 2590.712(a)(1), and 45 CFR 146.136(a)(1) from the 
beginning of the general rule of the design and application 
requirements to the beginning of the regulatory requirements for NQTLs 
at 26 CFR 54.9812-1(c)(4), 29 CFR 2590.712(c)(4), and 45 CFR 
146.136(c)(4), to make clear that plans and issuers should consider the 
fundamental purpose of MHPAEA in complying with all parts of the 
requirements for NQTLs. Additionally, the Departments are incorporating 
the phrase ``may not impose'' from the beginning of the proposed 
regulatory requirements for NQTLs, to make clear that this standard 
applies both to the design and application of NQTLs. The Departments 
are also replacing the word ``applied'' with ``applies'' in the clause 
describing ``the predominant NQTL that applies to substantially all 
medical/surgical benefits in the same classification.'' This adjustment 
from past to present tense is intended to clarify that plans and 
issuers should evaluate compliance with MHPAEA with respect to NQTLs 
that are currently imposed under the plan or coverage, rather than just 
those that might have been imposed at some point in the past.
b. Requirements Related to Design and Application of the NQTL--26 CFR 
54.9812-1(c)(4)(i), 29 CFR 2590.712(c)(4)(i), and 45 CFR 
146.136(c)(4)(i)
    The Departments proposed to redesignate the requirement at 26 CFR 
54.9812-1(c)(4)(i), 29 CFR 2590.712(c)(4)(i), and 45 CFR 
146.136(c)(4)(i) in the 2013 final regulations as paragraph 
(c)(4)(ii)(A) and amend it to align with the Departments' 
interpretation that a plan or issuer may not impose an NQTL with 
respect to mental health or substance use disorder benefits in any 
classification unless, under the terms of the plan (or health insurance 
coverage) as written and in operation, any processes, strategies, 
evidentiary standards, or other factors used in designing and applying 
(as compared to only applying, as under the 2013 final regulations) the 
NQTL to mental health and substance use disorder benefits are 
comparable to, and are applied no more stringently than those used in 
designing and applying the limitation with respect to medical/surgical 
benefits in the classification. To codify this interpretation, and for 
consistency with the statutory language added by the CAA, 2021, the 
Departments proposed to revise the regulatory text to make this 
requirement with respect to designing the NQTL explicit.
    Some commenters generally supported the proposed design and 
application requirements as part of an overall framework for evaluating 
compliance with MHPAEA's requirements with respect to NQTLs. Some 
commenters indicated that they have encountered barriers in identifying 
whether plans and issuers comply with MHPAEA's requirements, and this 
proposal would help them identify whether the plan or issuer is 
compliant with respect to the design and application of NQTLs. Other 
commenters generally opposed the proposed changes to the design and 
application requirements. One commenter also stated that the design and 
application requirements would not improve benefit quality and would 
also constitute an impermissible retroactive application of the 
regulation in the case of regulated entities that were not required to 
comply with MHPAEA when they designed their benefit plans.
    With respect to commenters' concern that the design and application 
requirements would not improve benefit quality, the Departments 
anticipate that greater clarity with respect to these requirements, 
including the definitions of the terms ``processes,'' ``strategies,'' 
``evidentiary standards,'' and ``factors'' under these final rules, as 
discussed earlier in this preamble, will help plans and issuers assess 
their compliance and remedy any parity violations, which will result in 
improved benefit quality overall. The Departments also disagree with 
the concern expressed by commenters that the design and application 
requirements impermissibly apply to plans and issuers that were not 
required to comply with MHPAEA when they designed their benefit plans. 
As stated earlier in this preamble, this provision codifies the 
Departments' longstanding interpretation of the design and application 
requirements and the CAA, 2021 amendments to the MHPAEA statute. The 
CAA, 2021 amendments apply generally to plans and issuers that offer 
both medical/surgical benefits and mental health or substance use 
disorder benefits and impose NQTLs on mental health or substance use 
disorder benefits. Congress did not exempt plans or issuers whose plans 
or benefit designs predated these requirements, and the Departments 
similarly did not take such an approach in implementing the 2010 
interim final regulations or the 2013 final regulations. In fact, as 
described in more detail later in this preamble, Congress included a 
provision in the CAA, 2023 that sunsets the option for self-funded non-
Federal governmental plans to elect to opt out of compliance with 
respect to MHPAEA, so that plans that previously were exempt from the 
requirements as a result of an opt-out election will no longer be able 
to make such an election.
    The Departments are finalizing as proposed the general rule with 
respect to the design and application requirements for NQTLs, with a 
few minor amendments. Accordingly, this provision clarifies that to 
satisfy these requirements, a plan or issuer must consider, as part of 
its assessment of an NQTL's compliance with the no more restrictive 
requirement, whether any processes, strategies, evidentiary standards, 
or other factors used in designing and applying the NQTL to mental 
health or substance use disorder benefits in the classification are 
comparable to, and are applied no more stringently than those used in 
designing and applying the limitation with respect to medical/surgical 
benefits in the classification. By requiring processes, strategies, 
evidentiary standards, or other factors used to be comparable to and 
applied no more stringently than, the design and application 
requirements

[[Page 77604]]

of these final rules give meaning to the statutory terms 
``substantially all'' and ``predominant.'' By making explicit in these 
final rules the Departments' interpretation of the design and 
application requirements, and codifying the requirements of the CAA, 
2021, this provision will help plans and issuers better understand 
their MHPAEA compliance obligations with respect to NQTLs, by 
emphasizing that, as written and in operation, the design of an NQTL is 
equally relevant as how it is applied. The design and application 
requirements of these final rules will also ensure that plans and 
issuers do not place greater burdens on access to mental health and 
substance use disorder benefits as compared to medical/surgical 
benefits.
    The Departments note that a plan or issuer must comply with the 
relevant requirements under these final rules with respect to NQTLs 
applicable to mental health or substance use disorder benefits once the 
final rules become applicable to the plan or coverage, including with 
respect to any NQTLs that were developed and imposed when a plan or 
issuer was not subject to MHPAEA and that continue to be imposed after 
the applicability date. However, these final rules are not applicable 
to an NQTL imposed with respect to mental health or substance use 
disorder benefits for any such prior period of time (including a period 
when MHPAEA was not applicable).
    In these final rules, the Departments are codifying the design and 
application requirements at 26 CFR 54.9812-1(c)(4)(i)(A), 29 CFR 
2590.712(c)(4)(i)(A), and 45 CFR 146.136(c)(4)(i)(A), rather than as 
proposed at 26 CFR 54.9812-1(c)(4)(ii)(A), 29 CFR 
2590.712(c)(4)(ii)(A), and 45 CFR 146.136(c)(4)(ii)(A) because, as 
discussed earlier in this preamble, these final rules structure the 
design and application requirements as part of the statutory no more 
restrictive requirement, rather than as a unique prong of the three 
requirements for NQTLs included in the proposed rules. In addition, the 
Departments are making a technical correction by amending the 
regulatory text to refer to health insurance coverage, rather than an 
issuer, to generally use consistent terminology throughout the 
regulations. Finally, as noted earlier in this preamble, these final 
rules move the reference to 26 CFR 54.9812-1(a)(1), 29 CFR 
2590.712(a)(1), and 45 CFR 146.136(a)(1) from the beginning of the 
general rule of the design and application requirements to the 
beginning of the regulatory requirements for NQTLs at 26 CFR 54.9812-
1(c)(4), 29 CFR 2590.712(c)(4), and 45 CFR 146.136(c)(4).
Prohibition on Discriminatory Factors and Evidentiary Standards
    The proposed rules would add a new provision that, for purposes of 
determining comparability and stringency under the design and 
application requirements of proposed 26 CFR 54.9812-1(c)(4)(ii)(A), 29 
CFR 2590.712(c)(4)(ii)(A), and 45 CFR 146.136(c)(4)(ii)(A), plans and 
issuers would be prohibited from relying upon any factor or evidentiary 
standard if the information, evidence, sources, or standards on which 
the factor or evidentiary standard is based discriminate against mental 
health or substance use disorder benefits as compared to medical/
surgical benefits. The proposed rules stated that information would be 
considered to discriminate against mental health or substance use 
disorder benefits if it is biased or not objective, in a manner that 
results in less favorable treatment of mental health or substance use 
disorder benefits, based on all the relevant facts and circumstances. 
Such relevant facts and circumstances would include, but not be limited 
to, the source of the information, the purpose or context of the 
information, and the content of the information. Therefore, under the 
proposed rules, plans and issuers would not be permitted to rely on 
information that reflects bias, as those factors or evidentiary 
standards would be discriminatory.
    For this purpose, the Departments stated in the proposed rules that 
information resulting in the less favorable treatment of mental health 
and substance use disorder benefits without legitimate justification or 
that is otherwise not objective would be considered to be biased and to 
discriminate against mental health and substance use disorder benefits. 
When determining which information, evidence, sources, or standards 
should inform the factors or evidentiary standards used to design or 
apply an NQTL, plans and issuers would not be permitted under the 
proposed rules to use information, evidence, sources, or standards if 
they are biased in favor of imposing greater restrictions on access to 
covered mental health and substance use disorder benefits or not 
objective, based on all the relevant facts and circumstances. The 
Departments also proposed that impartially applied independent 
professional medical or clinical standards and fraud, waste, and abuse 
measures that meet specific requirements would qualify for an exception 
and would not be considered to discriminate against mental health or 
substance use disorder benefits.
    Additionally, in the preamble to the proposed rules the Departments 
noted that the proposed prohibition on discriminatory factors and 
evidentiary standards would prohibit plans and issuers from relying on 
historical plan data or other historical information from a time when 
the plan or coverage was not subject to MHPAEA or was in violation of 
MHPAEA's requirements, where the use of such data results in less 
favorable treatment of mental health and substance use disorder 
benefits. The Departments provided an example illustrating that a plan 
or issuer would not be permitted to calculate reimbursement rates based 
on historical data on total plan spending for each specialty that is 
divided between mental health and substance use disorder providers and 
medical/surgical providers, when the total spending by the plan was 
based on a time period when the plan or coverage was not subject to 
MHPAEA or was in violation of MHPAEA, if the data result in less 
favorable treatment of mental health and substance use disorder 
benefits. Consequently, under the framework in the proposed rules, 
plans and issuers could not use such data to develop a factor or 
evidentiary standard for the design or application of an NQTL to mental 
health or substance use disorder benefits. The proposed rules stated, 
to the extent a plan or issuer relies on any factor or evidentiary 
standard that discriminates against mental health or substance use 
disorder benefits, or any information, evidence, sources, or standards 
that inform such factors or evidentiary standards to design and apply 
NQTLs, the plan or issuer would violate the prohibition on 
discriminatory factors and evidentiary standards set forth in proposed 
26 CFR 54.9812-1(c)(4)(ii)(B), 29 CFR 2590.712(c)(4)(ii)(B), and 45 CFR 
146.136(c)(4)(ii)(B).
    Many commenters expressed general support for this provision of the 
proposed rules. For example, one commenter noted that the prohibition 
on discriminatory factors and evidentiary standards would more 
effectively protect against the inappropriate application of NQTLs 
that, although appearing to be compliant with MHPAEA as written, have a 
disproportionately negative effect on access to mental health and 
substance use disorder benefits. Some commenters also indicated that 
the proposed provision is consistent with the text and purpose of 
MHPAEA, as well as the ACA, and favored a broad interpretation

[[Page 77605]]

of the requirement to address particular examples of discrimination by 
plans and issuers, to which some of them expressly cited. Other 
commenters expressed opposition to the proposed prohibition on 
discriminatory factors and evidentiary standards. Some of these 
commenters stated that the proposal would be administratively 
burdensome, and it would be difficult for plans and issuers to 
operationalize due to ambiguity and inherent subjectivity. Some 
commenters opposed to the proposed prohibition stated that it is 
duplicative of the proposed relevant data evaluation requirements. 
These commenters thought the prohibition on discriminatory factors and 
evidentiary standards should be eliminated as superfluous, because the 
required evaluation of outcomes data under the proposed rules is 
intended to ensure that factors are applied no more stringently to 
mental health and substance use disorder benefits than medical/surgical 
benefits and do not result in a material difference in access.
    Some commenters expressed concern that the proposed requirement 
that information must not be biased and must be objective (which is 
based on facts and circumstances) is too subjective, can only be 
determined retroactively (yet must be applied prospectively), and is 
too difficult to apply for plans or issuers to be certain of 
compliance. One commenter requested clarification on the documentation 
and evidence required to demonstrate the absence of bias. Another 
commenter expressed concern that plans may not have the ability to 
prove that information is unbiased and objective.
    One commenter stated that it is unclear whether the Departments 
intend to focus on the factors and evidentiary standards themselves or 
on the effects of using those factors and standards. Some commenters 
assumed that whether a factor or evidentiary standard is discriminatory 
would be based on an evaluation of outcomes, and that therefore any 
disparity in outcomes data could be viewed as use of a discriminatory 
factor or evidentiary standard. These commenters requested examples of 
outcomes that would demonstrate compliance. In addition, many 
commenters requested examples of discriminatory factors and evidentiary 
standards and of nondiscriminatory information and data sources. 
Several commenters requested the Departments to make clear that plans 
and issuers may not establish compliance by relying on a fee schedule 
used by Medicare, although another commenter requested that plans and 
issuers be able to access a safe harbor if they paid above-Medicare 
rates.
    After considering commenters' feedback, the Departments are 
finalizing the prohibition on discriminatory factors and evidentiary 
standards with modifications. As the Departments stated in the preamble 
to the proposed rules this provision will help address the concern that 
various factors and evidentiary standards that plans and issuers have 
relied on to design NQTLs with respect to mental health or substance 
use disorder benefits might themselves discriminate against mental 
health and substance use disorder benefits by treating them in a less 
favorable manner. At the same time, the Departments acknowledge 
commenters' concerns about potential ambiguities in the proposed 
prohibition on discriminatory factors and evidentiary standards, 
questions about whether this provision is duplicative of other parts of 
the proposed rules, and confusion about how to operationalize the 
prohibition.
    In response to these concerns, and to assist plans and issuers in 
complying with the prohibition on discriminatory factors and 
evidentiary standards in these final rules, the Departments have 
modified the prohibition by providing additional clarity regarding what 
it means for information, evidence, sources, or standards to be 
``biased or not objective.'' The final rules both clarify the 
prohibition in a manner to ensure that it can be applied prospectively 
and revise it to expressly provide that potentially biased or not 
objective information, evidence, sources, or standards can be 
corrected, cured, or supplemented, and then relied upon by a plan or 
issuer to inform a factor or evidentiary standard that is not 
discriminatory. The Departments also provide additional examples of 
discriminatory factors and evidentiary standards later in this 
preamble.
    First, with respect to the general prohibition on discriminatory 
factors and evidentiary standards, these final rules at 26 CFR 54.9812-
1(c)(4)(i)(B), 29 CFR 2590.712(c)(4)(i)(B), and 45 CFR 
146.136(c)(4)(i)(B) \70\ provide that, for purposes of determining 
comparability and stringency under 26 CFR 54.9812-1(c)(4)(i)(A), 29 CFR 
2590.712(c)(4)(i)(A), and 45 CFR 146.136(c)(4)(i)(A), a plan (or health 
insurance coverage) may not rely upon discriminatory factors and 
evidentiary standards to design an NQTL to be imposed on mental health 
or substance use disorder benefits. The Departments intend that the 
focus of this prohibition be specifically on the design of NQTLs, to 
further distinguish the prohibition on discriminatory factors and 
evidentiary standards from the relevant data evaluation requirements. 
These final rules provide the necessary clarity for plans and issuers 
to determine whether information, evidence, sources, or standards are 
biased or not objective, and if so, cannot be used as the basis for a 
factor or evidentiary standard used to design an NQTL applicable to 
mental health or substance use disorder benefits.
---------------------------------------------------------------------------

    \70\ As noted earlier in this preamble, the Departments are 
codifying the design and application requirements (including the 
prohibition on discriminatory factors and evidentiary standards) at 
26 CFR 54.9812-1(c)(4)(i), 29 CFR 2590.712(c)(4)(i), and 45 CFR 
146.136(c)(4)(i), rather than as proposed at 26 CFR 54.9812-
1(c)(4)(ii), 29 CFR 2590.712(c)(4)(ii), and 45 CFR 
146.136(c)(4)(ii), because these final rules structure the design 
and application requirements as part of the no more restrictive 
requirement, rather than as a unique prong of the 3-part test 
proposed in the proposed rules.
---------------------------------------------------------------------------

    Specifically, these final rules state that a factor or evidentiary 
standard is discriminatory if the information, evidence, sources, or 
standards on which the factor or evidentiary standard are based are 
biased or not objective in a manner that discriminates against mental 
health or substance use disorder benefits as compared to medical/
surgical benefits. This language is similar to that included under 
proposed 26 CFR 54.9812-1(c)(4)(ii)(B), 29 CFR 2590.712(c)(4)(ii)(B), 
and 45 CFR 146.136(c)(4)(ii)(B) but adds the phrase ``is biased or not 
objective in a manner that,'' preceding the word ``discriminates.'' 
This phrase, in conjunction with the other changes to the prohibition 
on discriminatory factors and evidentiary standards discussed later in 
this preamble, was modified in response to comments and is intended to 
help clarify that a plan or issuer is expected to assess whether the 
information, evidence, sources, or standards on which each factor or 
evidentiary standard are based are biased or not objective in a manner 
that discriminates against mental health or substance use disorder 
benefits as compared to medical/surgical benefits. This analysis is 
distinct from the final rules' requirement to compare the comparability 
and stringency of factors and evidentiary standards used to design and 
apply an NQTL.
    Second, the Departments are finalizing a modified version of the 
provision originally proposed under 26 CFR 54.9812-1(c)(4)(ii)(B)(3), 
29 CFR 2590.712(c)(4)(ii)(B)(3), and 45 CFR 146.136(c)(4)(ii)(B)(3) as 
26 CFR 54.9812-1(c)(4)(i)(B)(1), 29 CFR 2590.712(c)(4)(i)(B)(1), and 45 
CFR 146.136(c)(4)(i)(B)(1) of these final rules. This provision of the 
proposed rules

[[Page 77606]]

provided that information is considered to discriminate against mental 
health or substance use disorder benefits if it is biased or not 
objective, in a manner that results in less favorable treatment of 
mental health or substance use disorder benefits, based on all the 
relevant facts and circumstances. As mentioned earlier in this 
preamble, the Departments received many comments opposing this 
provision as proposed, including comments expressing confusion as to 
how it is different from the relevant data evaluation requirements, 
questions regarding the kind of documentation and evidence needed to 
show compliance, and concern that it is subjective and difficult to 
operationalize.
    The prohibition on discriminatory factors and evidentiary standards 
is intended to work together with the other provisions of these final 
rules, including the relevant data evaluation requirements. Like all 
the provisions of these final rules, the provision further implements 
the statutory requirement that NQTLs be no more restrictive with 
respect to mental health or substance use disorder benefits than the 
predominant limitations applicable to substantially all medical/
surgical benefits. The test specifically focuses on the importance of 
ensuring that the factors and evidentiary standards relied upon by 
plans and issuers in designing NQTLs do not have built-in biases (at 
the time NQTLs are designed) against mental health or substance use 
disorder benefits as compared to medical/surgical benefits. To the 
extent plans and issuers rely upon factors and evidentiary standards to 
design NQTLs that systematically disfavor access or are specifically 
designed to disfavor access to mental health and substance use disorder 
benefits, the resultant NQTLs are more restrictive with respect to 
mental health or substance use disorder benefits than for medical/
surgical benefits.
    The Departments note that a factor or evidentiary standard may be 
based on or include information that solely relates to medical/surgical 
benefits (and is silent or without corollary with respect to mental 
health or substance use disorder benefits). Such a factor or 
evidentiary standard is not considered discriminatory for this purpose. 
For example, a plan can reasonably rely on a source of information on 
the clinical efficacy of a treatment or service to inform a factor used 
to design a medical management NQTL, even though that source does not 
address the clinical efficacy of any treatment of any mental health 
conditions or substance use disorders, without violating the 
prohibition on discriminatory factors and evidentiary standards. 
However, the use of such factor or evidentiary standard must comply 
with the design and application requirements, as described earlier in 
this preamble.
    In response to comments to provide additional clarity, the final 
rules elaborate on the meaning of the phrase ``biased and not objective 
in a manner that discriminates against mental health or substance use 
disorder benefits.'' Specifically, these final rules provide that 
information, evidence, sources, or standards are considered to be 
biased or not objective in a manner that discriminates against mental 
health or substance use disorder benefits as compared to medical/
surgical benefits if, based on all the relevant facts and 
circumstances, they systematically disfavor access or are specifically 
designed to disfavor access to mental health or substance use disorder 
benefits as compared to medical/surgical benefits.
    For purposes of determining whether information, evidence, sources, 
or standards are considered to be biased or not objective under these 
final rules, relevant facts and circumstances may include, but are not 
limited to, the reliability of information, evidence, sources, or 
standards, including any underlying data and the independence of the 
information, evidence, sources, and standards relied upon. The 
Departments note that internal data or information, such as claims 
data, would generally not be considered independent, but would not 
necessarily be considered discriminatory on that basis alone. In the 
Departments' view, independence is a relevant fact and circumstance for 
determining whether information, evidence, sources, or standards are 
considered to be biased or not objective. For example, a standard that 
is created or funded by the plan or issuer, or its service provider, 
would likely lack independence compared to a standard created by an 
impartial third party or governmental entity, and might require strong 
indicators of reliability in order to demonstrate that it is objective 
and unbiased. Additionally, relevant facts and circumstances include 
the analyses and methodologies employed to select the information, 
evidence, sources, or standards, and the consistency of their 
application; and any known safeguards deployed to prevent reliance on 
skewed data or metrics when determining whether they are biased or not 
objective. The Departments note that these final rules only provide 
examples, and not a comprehensive list, of relevant facts and 
circumstances that indicate information, evidence, sources, or 
standards are biased or not objective. Because plans and issuers rely 
on myriad factors and evidentiary standards to design NQTLs for their 
own unique benefit designs, this evaluation necessarily will be 
specific to the particular plan or coverage.
    Under these final rules, information, evidence, sources, and 
standards are not considered biased or not objective for purposes of 
the prohibition on discriminatory factors and evidentiary standards, if 
a plan or issuer has taken steps necessary to address the bias or lack 
of objectivity by correcting, curing, or supplementing the information, 
evidence, sources, or standards that would have been biased or not 
objective in the absence of such steps. If information, evidence, 
sources, or standards are corrected, cured, or supplemented, they may 
be used by plans and issuers as the basis for factors and evidentiary 
standards used to design an NQTL.
    Several commenters asked about the use of a fee schedule used by 
Medicare and CMS-set standards, such as network time and distance 
standards, by a plan or issuer to inform plan design. For example, some 
plans use the Medicare Physician Fee Schedule \71\ to establish base 
rates for in-network physician services. The Departments do not 
consider fee schedules used by Medicare and standards set by CMS to be 
biased or not objective, as defined under these rules, when used as the 
basis for a factor or evidentiary standard to design an NQTL such as 
reimbursement rate methodology.
---------------------------------------------------------------------------

    \71\ The Medicare Physician Fee Schedule is developed by CMS. To 
develop the Medicare Physician Fee Schedule, CMS utilizes 
recommendations from an independent assessment by a multi-specialty 
body and other market-based information sources, as well as 
independent assessment by CMS medical officers, to develop proposed 
relative value units for each physician service. CMS then engages in 
notice and comment rulemaking, including consideration of public 
comments, before establishing payment rates for specific services. 
Furthermore, CMS has made, and continues to make, numerous 
adjustments to the underlying methodology to increasingly ensure 
appropriate reimbursement for services paid under the Medicare 
Physician Fee Schedule, including behavioral health services. See, 
e.g., Medicare and Medicaid Programs; CY 2024 Payment Policies Under 
the Physician Fee Schedule and Other Changes to Part B Payment and 
Coverage Policies; Medicare Shared Savings Program Requirements; 
Medicare Advantage; Medicare and Medicaid Provider and Supplier 
Enrollment Policies; and Basic Health Program, 88 FR 78818 (Nov. 16, 
2023).
---------------------------------------------------------------------------

    The Departments note, however, that the mere use of the Medicare 
Physician Fee Schedule, for example, as one type of information, 
evidence, source, or standard that informs a factor used to design an 
NQTL does not automatically

[[Page 77607]]

render the NQTL permissible. For example, in most cases, a plan would 
be unable to justify a reimbursement rate methodology that paid 
physicians in medical/surgical specialties 125 percent of the Medicare 
Physician Fee Schedule rate and that paid physicians in mental health 
and substance use disorder specialties 75 percent of the Medicare 
Physician Fee Schedule rate.
    The Departments received several comments in support of the example 
included in the preamble to the proposed rules that illustrated the 
prohibition on plans' and issuers' reliance on historical plan data or 
other historical information from a time when the plan or coverage was 
not subject to MHPAEA, or not compliant with MHPAEA. Some commenters 
recognized that many plans and issuers have used their own historical 
data from a time when their plan or coverage was not subject to MHPAEA 
and have benefited from historic inequities in benefit structures that 
MHPAEA sought to prohibit. One commenter requested that this example be 
codified in the regulatory text of the final rules. The Departments 
agree that the example illustrating how the prohibition on 
discriminatory factors and evidentiary standards applies to the use of 
historical data and information to design an NQTL should be clearly set 
forth in the regulation text at 26 CFR 54.9812-1(c)(4)(ii)(B)(2), 29 
CFR 2590.712(c)(4)(ii)(B)(2), and 45 CFR 146.136(c)(4)(ii)(B)(2). To 
ensure compliance with this standard, plans and issuers that utilize 
historical data or information from a time when their plan or coverage 
was not subject to, or not compliant with, MHPAEA should ensure that 
the use of such data and information (for example, in cost calculations 
and controls) for mental health and substance use disorder benefits 
does not include, as a baseline, years when financial requirements and 
treatment limitations that would have been impermissible under MHPAEA 
were imposed on such benefits (unless they take steps to correct, cure, 
or supplement the data or information, as discussed earlier in this 
preamble).
    Some commenters provided other examples that they recommended 
including as illustrations of discriminatory factors and evidentiary 
standards in these final rules, including prior authorization for a 
prescription of buprenorphine to treat opioid use disorder (OUD) 
requiring additional licensure or certification for mental health and 
substance use disorder providers that is not required of similar 
medical/surgical providers; subjecting mental health and substance use 
disorder claims to different fraud, waste, and abuse processes, or 
requiring more documentation, than for medical/surgical claims; not 
covering nutrition counseling for the treatment of eating disorders 
while covering it for medical conditions; and requiring that mental 
health and substance use disorder claims and appeals be filed with a 
TPA, but not making this clear to enrollees, nor properly coordinating 
operations between the plan/issuer and TPA.
    However, many of these examples focus on the use of a factor to 
apply an NQTL to mental health and substance use disorder benefits in a 
manner that is not comparable or is more stringent than the use of the 
factor to apply an NQTL to medical/surgical benefits, or focus on the 
NQTL itself (rather than the discriminatory factor or evidentiary 
standard). The prohibition on discriminatory factors and evidentiary 
standards in these final rules, however, focuses on the information, 
evidence, sources, and standards that inform the factors and 
evidentiary standards used to design an NQTL. Factors and evidentiary 
standards that incorporate or otherwise rely on underlying data or 
information that systematically disfavor access or are specifically 
designed to disfavor access to mental health or substance use disorder 
benefits place a greater burden on access to such benefits. Therefore, 
these final rules prohibit the use of any factor or evidentiary 
standard to design an NQTL if the underlying information, evidence, 
sources, and standards are themselves biased or not objective in a 
manner that discriminates against mental health or substance use 
disorder benefits as compared to medical/surgical benefits, unless the 
plan or issuer takes steps to correct, cure, or supplement the 
information, evidence, sources and standards to address the bias or 
lack of objectivity.
    These final rules set forth a general rule to determine which 
specific factors and evidentiary standards (and the information, 
evidence, sources, and standards on which they are based) might or 
might not be biased and not objective in a manner that discriminates 
against mental health or substance use disorder benefits as compared to 
medical/surgical benefits. The Departments have provided new examples 
in these final rules illustrating the prohibition on discriminatory 
factors and evidentiary standards, which are discussed later in this 
preamble. The Departments acknowledge that these examples are not 
exhaustive and may provide additional examples in future guidance.
    Finally, as discussed in greater detail later in this preamble, the 
Departments are not finalizing the exceptions to the prohibition on 
discriminatory factors and evidentiary standards for independent 
professional medical or clinical standards and fraud, waste, and abuse 
measures. However, these final rules expressly clarify at 26 CFR 
54.9812-1(c)(4)(i)(B)(3), 29 CFR 2590.712(c)(4)(i)(B)(3), and 45 CFR 
146.136(c)(4)(i)(B)(3) that generally recognized independent 
professional medical or clinical standards and fraud and abuse measures 
that minimize the negative impact on access to appropriate mental 
health and substance use disorder benefits are not information, 
evidence, sources, or standards that are biased or not objective in a 
manner that discriminates against mental health or substance use 
disorder benefits as compared to medical/surgical benefits.
    The Departments recognize that commenters requested specificity as 
to what qualifies as independent professional medical or clinical 
standards. To ensure that they are not biased and are objective, 
independent professional medical or clinical standards should reflect 
the standards of care and clinical practice that are generally 
recognized in relevant clinical specialties across a range of settings 
of care and should be transparent. For example, sources that include 
such standards could be peer-reviewed scientific studies and medical 
literature, formal published recommendations of Federal Government 
agencies, drug labeling approved by the United States Food and Drug 
Administration (FDA), and recommendations of relevant nonprofit health 
care provider professional associations and specialty societies, 
including, but not limited to, patient placement criteria and clinical 
practice guidelines. Additionally, fraud and abuse measures should be 
reliably established through unbiased and objective data and narrowly 
tailored in a manner that minimizes the negative impact on access to 
appropriate mental health and substance use disorder benefits.
    These final rules also clarify that plans and issuers that rely on 
independent professional medical or clinical standards or fraud and 
abuse measures must comply with the general rule of the design and 
application requirements at 26 CFR 54.9812-1(c)(4)(i)(A), 29 CFR 
2590.712(c)(4)(i)(A), and 45 CFR 146.136(c)(4)(i)(A). If such a 
standard or measure is used as an NQTL, the plan or issuer also must 
comply with the relevant data evaluation requirements at 26 CFR 
54.9812-1(c)(4)(iii), 29 CFR

[[Page 77608]]

2590.712(c)(4)(iii), and 45 CFR 146.136(c)(4)(iii) in these final 
rules.
c. Illustrative, Non-Exhaustive List of NQTLs--26 CFR 54.9812-
1(c)(4)(ii), 29 CFR 2590.712(c)(4)(ii), and 45 CFR 146.136(c)(4)(ii)
    The proposed rules proposed to move the illustrative, non-
exhaustive list of NQTLs from 26 CFR 54.9812-1(c)(4)(ii), 29 CFR 
2590.712(c)(4)(ii), and 45 CFR 146.136(c)(4)(ii) to 26 CFR 54.9812-
1(c)(4)(iii), 29 CFR 2590.712 (c)(4)(iii), and 45 CFR 
146.136(c)(4)(iii) and make several minor changes to this list. First, 
the Departments proposed amendments to make clear that this 
illustrative list of NQTLs is non-exhaustive and that there are 
additional NQTLs not captured in the list. The Departments also 
proposed to amend the illustrative, non-exhaustive list of NQTLs to 
replace ``[s]tandards for provider admission to participate in a 
network, including reimbursement rates'' with ``standards related to 
network composition, including, but not limited to, standards for 
provider and facility admission to participate in a network or for 
continued network participation, including methods for determining 
reimbursement rates, credentialing standards, and procedures for 
ensuring the network includes an adequate number of each category of 
provider and facility to provide covered services under the plan or 
coverage.'' Additionally, the Departments proposed to amend the 
description of the illustrative NQTL ``plan methods for determining 
usual, customary, and reasonable charges'' to encompass a broader range 
of methods for determining out-of-network rates, such as allowed 
amounts; usual, customary, and reasonable charges; or application of 
other external benchmarks for out-of-network rates. Finally, the 
Departments proposed to add a specific reference to prior authorization 
requirements as an example of a medical management standard limiting or 
excluding benefits based on medical necessity or medical 
appropriateness, consistent with Example 1 in 26 CFR 54.9812-
1(c)(4)(iii), 29 CFR 2590.712(c)(4)(iii), and 45 CFR 146.136(c)(4)(iii) 
of the 2013 final regulations.
    Some commenters supported the clarification in the proposed rules 
that the illustrative list is non-exhaustive and that there are 
additional NQTLs not included in the list. In general, many commenters 
found the list to be helpful for plans and issuers to identify NQTLs. 
Some of these commenters pointed out that the non-exhaustive nature of 
the list would allow new NQTLs developed by plans and issuers to fall 
under the scope of the requirements in these final rules. One commenter 
also noted that the definition of an NQTL is sufficiently clear such 
that an exhaustive list would not be needed to put plans or issuers on 
notice of their compliance obligations.
    Other commenters requested that the Departments instead provide an 
exhaustive list of NQTLs to eliminate uncertainty, promote consistency, 
and clarify plans' and issuers' compliance obligations. Several of 
these commenters suggested that the Departments update such an 
exhaustive list as new NQTLs are identified and allow adequate time for 
plans and issuers to come into compliance with respect to such NQTLs. 
Other commenters advocated for an approach where an exhaustive list of 
NQTLs would also represent the scope of NQTLs for which the relevant 
Secretary could request a comparative analysis. Some of these 
commenters requested that to the extent the relevant Secretary 
requested a comparative analysis for an NQTL not on the list, plans and 
issuers be provided with additional time to respond.
    The Departments agree with the commenter generally stating that the 
definition of an NQTL under 26 CFR 54.9812-1(a), 29 CFR 2590.712(a), 
and 45 CFR 146.136(a), in addition to the non-exhaustive, illustrative 
list of NQTLs, is sufficient to put plans and issuers on notice that a 
given plan provision would fall under the definition of an NQTL. 
Therefore, the Departments are finalizing as proposed the clarification 
that this illustrative list of NQTLs is non-exhaustive.
    The Departments decline to provide an exhaustive list of NQTLs, as 
requested by commenters, in these final rules; however, as described 
further below, the Departments may consider issuing separate guidance 
to add additional examples if needed. Plans and issuers, rather than 
the Departments, are best positioned to initially identify NQTLs, 
including any NQTLs that plans and issuers newly implement as their 
plan or coverage designs evolve over time. MHPAEA does not limit the 
scope of NQTLs that plans and issuers may impose on mental health and 
substance use disorder benefits. However, for any NQTLs applicable to 
such benefits, a plan or issuer must comply with MHPAEA and its 
implementing regulations. Any exhaustive list of NQTLs published by the 
Departments would likely lag behind those actually utilized by plans 
and issuers due to this information gap, along with the wide 
variability in NQTLs that exist now and could exist in the future. 
Furthermore, while some commonalities exist, plans and issuers 
generally do not use uniform nomenclature to refer to their medical 
management techniques or other NQTLs, making the task of identifying an 
exhaustive list difficult, if not impossible.
    An exhaustive list of NQTLs that does not include the full scope of 
NQTLs utilized by plans and issuers at any given time would undermine 
the fundamental purpose of MHPAEA and these final rules. While the 
Departments acknowledge and have considered plans' and issuers' 
requests for a finite list of NQTLs for which the Departments may 
request comparative analyses, the exhaustive nature of such a list 
would leave open a compliance loophole by incentivizing plans and 
issuers to wait to evaluate, document, and address compliance for an 
NQTL that is newly developed or has not come to the attention of the 
Departments. The approach some commenters suggested to expressly limit 
the comparative analysis requirement under 26 CFR 54.9812-2, 29 CFR 
2590.712-1, and 45 CFR 146.137 to only those NQTLs identified in an 
exhaustive list is similarly untenable due to a foreseeable mismatch 
between the NQTLs included on such an exhaustive list, and those 
utilized by plans and issuers over time, particularly where the 
Departments may receive a complaint or have reason to believe there may 
be a potential violation. The Departments recognize the desire of plans 
and issuers to have a list of NQTLs on which the Departments will focus 
their enforcement efforts. The Departments highlight that the most 
recent reports to Congress on MHPAEA contain lists of the NQTLs on 
which the Departments have focused their enforcement efforts, and the 
NQTLs the Departments have mostly commonly found to be 
noncompliant.\72\ Additionally, the 2020 MHPAEA Self-Compliance Tool 
includes an illustrative, non-exhaustive list of NQTLs.\73\ The 
statute, however, requires the Departments to request

[[Page 77609]]

comparative analyses from a plan or issuer for any NQTL that involves 
potential violations of MHPAEA or complaints regarding noncompliance 
with MHPAEA that concern NQTLs. To limit the Departments to requesting 
comparative analyses for only certain NQTLs identified in a list would 
not only be inconsistent with the statute but would also limit the 
ability of the Departments to dynamically respond to new NQTLs that 
plans and issuers design and apply that may restrict participant and 
beneficiary access to mental health and substance use disorder benefits 
as compared to medical/surgical benefits.

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

    Additionally, allowing plans and issuers to categorically have 
additional time to assemble a comparative analysis for NQTLs that are 
not on a finite list of NQTLs, as requested by commenters, would also 
be inconsistent with the statutory requirement that, without exception, 
plans and issuers perform and document such comparative analyses of 
NQTLs applicable to mental health or substance use disorder benefits, 
beginning 45 days after the enactment of the CAA, 2021, and would 
result in the post-hoc justifications addressed with the CAA, 2021's 
enactment.\74\ The Departments nonetheless acknowledge commenters' 
requests for additional guidance about plan provisions that would be 
considered to be NQTLs and intend to provide additional examples of 
NQTLs through future reports to Congress, updates to the 2020 MHPAEA 
Self-Compliance Tool, and other guidance.

    The Departments received a handful of comments on the proposed 
expansion of the illustrative list's description of standards for 
provider admission to participate in a network, including reimbursement 
rates, to also refer to standards for provider and facility admission 
to participate in a network or for continued network participation, 
including methods for determining reimbursement rates, credentialing 
standards, and procedures for ensuring the network includes an adequate 
number of each category of provider and facility to provide covered 
services under the plan or coverage. Some commenters supported these 
proposed amendments to ensure that patients have an adequate provider 
network. Others suggested that parity requirements for provider 
networks should address the administrative burden and credentialing 
requirements on providers when joining networks, which may limit 
network adequacy. The Departments are finalizing this amendment as 
proposed. The Departments agree with commenters who stated that MHPAEA 
applies to credentialing standards, as well as the procedures to join a 
network, and note that methods for determining reimbursement rates, 
credentialing standards, and procedures for ensuring the network 
includes an adequate number of each category of provider and facility 
to provide services under the plan or coverage are intended to be 
interpreted broadly, consistent with the fundamental purpose of MHPAEA. 
Because these final rules do not retain the proposed mathematical 
substantially all and predominant tests, the illustrative list appears 
in these final rules at 26 CFR 54.9812-1(c)(4)(ii), 29 CFR 
2590.712(c)(4)(ii), and 45 CFR 146.136(c)(4)(ii) instead of 26 CFR 
54.9812-1(c)(4)(iii), 29 CFR 2590.712(c)(4)(iii), and 45 CFR 
146.136(c)(4)(iii) as in the proposed rules.
d. Required Use of Outcomes Data and Special Rule for NQTLs Related to 
Network Composition--26 CFR 54.9812-1(c)(4)(iii), 29 CFR 
2590.712(c)(4)(iii), and 45 CFR 146.136(c)(4)(iii)
    In the proposed rules, the Departments proposed to amend the 2013 
final regulations to add a requirement that, when designing and 
applying an NQTL, a plan or issuer must collect and evaluate relevant 
data in a manner reasonably designed to assess the impact of the NQTL 
on access to mental health and substance use disorder benefits and 
medical/surgical benefits, and consider the impact as part of the 
plan's or issuer's analysis of whether the NQTL, in operation, complies 
with the proposed no more restrictive requirement and the design and 
application requirements. The proposed rules included the general types 
of data that plans and issuers would have to collect and evaluate with 
regard to all NQTLs and additional data sets that would have to be 
collected and evaluated for NQTLs related to network composition 
standards. To the extent the relevant data collected and evaluated by 
the plan or issuer show material differences in access to mental health 
benefits and substance use disorder benefits as compared to medical/
surgical benefits, under the proposed rules, the differences would be 
considered a strong indicator that the plan or issuer violated the 
proposed rules. In these instances, a plan or issuer would be required 
to take reasonable action to address any material differences in access 
as necessary to ensure compliance, in operation, with proposed 26 CFR 
54.9812-1(c)(4)(i) and (ii), 29 CFR 2590.712(c)(4)(i) and (ii), and 45 
CFR 146.136(c)(4)(i) and (ii), and would also be required to document 
the action that has been or is being taken by the plan or issuer to 
mitigate any material differences in access in the plan's or issuer's 
comparative analysis for the NQTL in that classification.
    Additionally, the Departments noted in the preamble to the proposed 
rules their concerns about standards related to network composition and 
other related NQTLs. Specifically, the Departments noted that network 
composition is the result of the design and application of myriad NQTLs 
and is informed by various processes, strategies, evidentiary 
standards, and other factors, many of which interact in complex ways. 
The Departments also expressed concern that NQTLs related to network 
composition inherently impact a participant's or beneficiary's access 
to mental health and substance use disorder benefits. Accordingly, the 
proposed rules included a special rule applicable to NQTLs related to 
network composition. Specifically, under the proposed rules, when 
designing and applying one or more NQTLs related to network composition 
standards, a plan or issuer would fail to meet the requirements of 
proposed 26 CFR 54.9812-1(c)(4)(i) and (ii), 29 CFR 2590.712(c)(4)(i) 
and (ii), and 45 CFR 146.136(c)(4)(i) and (ii), in operation, if the 
relevant data show material differences in access to in-network mental 
health benefits and substance use disorder benefits as compared to in-
network medical/surgical benefits in a classification.
    The Departments also proposed that plans and issuers would not be 
required to comply with the relevant data evaluation requirements for 
NQTLs that impartially apply independent professional medical or 
clinical standards. However, proposed 26 CFR 54.9812-1(c)(4)(iv)(D), 29 
CFR 2590.712(c)(4)(iv)(D), and 45 CFR 146.136(c)(4)(iv)(D) did not 
provide a comparable exception for fraud, waste, and abuse measures, as 
the Departments stated these tools, while important, are more likely to 
result in NQTLs that improperly restrict access to mental health or 
substance use disorder benefits and therefore the impact of those NQTLs 
should be assessed.
In General
    The Departments received many comments expressing general support 
for the proposal to require plans and issuers to collect and evaluate 
relevant data to assess an NQTL's impact on

access to mental health and substance use disorder benefits and 
medical/surgical benefits, including the proposed requirement related 
to data for network composition NQTLs. These commenters noted that the 
data collection and evaluation requirements would promote transparency 
and compliance with MHPAEA, stating that collecting and evaluating 
outcomes data is essential to assessing in-operation compliance and 
that plans and issuers had failed to conduct and share such analyses. 
Other commenters noted that col
