Mental Health Parity Rule Paused: The Actuarial Liability Gap

Federal regulators suspended enforcement of the 2024 mental health parity rule's toughest provisions in May 2025, and on March 30, 2026 told a federal court they intend to replace the rule entirely by December 31, 2026.

The baseline they paused against is unflattering. All 210 comparative analyses the Department of Labor reviewed in its last report to Congress failed to demonstrate compliance on first submission.

Key Takeaways

• Four requirements are paused, not the statute. The fiduciary certification, the response timeline, the meaningful-benefit standard and the discriminatory-factors prohibition are unenforced; the 2013 regulations and the CAA 2021 comparative analysis duty are not.
• 210 of 210 analyses failed on first review, EBSA's fourth consecutive report to Congress finding a materially deficient starting rate.
• 183 insufficiency letters covering more than 330 NQTLs followed 199 initial request letters between February 2021 and July 2023.
• Georgia fined 11 insurers nearly $25 million in January 2026 for conduct during calendar year 2022, a four-year gap between the conduct and the penalty.
• Roughly 25% of EBSA's enforcement program now goes to NQTL work across about 2.5 million plans covering some 133 million people.

What the Pause Suspends and What Still Applies

The 2024 final rule added four things to the parity regulations: a fiduciary certification of the comparative analysis, a fixed response timeline once a regulator or participant asks for it, a meaningful-benefit standard requiring parity in outcomes rather than design alone, and a prohibition on discriminatory factors and evidentiary standards used to build the analysis.

On May 15, 2025 the Departments of Labor, Health and Human Services and Treasury said they would not enforce those four "prior to a final decision in the litigation," plus an 18-month tail after it. On March 30, 2026 the same departments told the DC court hearing the ERISA Industry Committee's challenge that rather than defend the rule they will issue a new proposed rule by December 31, 2026 with significant revisions. The case has been stayed since May 2025 on 90-day status reports, the next due September 30, 2026.

What did not pause is the core. The 2013 regulations and the Consolidated Appropriations Act, 2021 requirement still oblige a group health plan to perform a comparative analysis of non-quantitative treatment limitations and produce it on request. A plan must still show in writing that any process, strategy or evidentiary standard limiting mental health and substance use disorder benefits is comparably applied to medical and surgical benefits.

The pause removed the newest layer of proof and the deadline pressure. It did not remove the obligation, and the distance between not currently enforced and not owed is where the exposure sits.

The Deficiency Rate Is the Exposure Estimate

There is no public loss triangle for parity violations, but the audit history works as a proxy. Between February 2021 and July 2023 the department issued 199 initial letters covering more than 480 distinct NQTLs and followed with 183 insufficiency letters addressing more than 330 of them. Its 2023 report to Congress found all 210 analyses reviewed that cycle failed on first submission.

Most were cured through follow-up documentation rather than penalty, and the cost of curing is the number worth carrying. Enforcement has since moved from letters to findings: as of March 2026, DOL had issued final noncompliance determinations to 5 plans covering 7 NQTLs and CMS to 6 plans covering 10. None of that machinery went away in May 2025; it stopped pointing at the 2024 rule's additions.

A deficiency that exists today but has drawn no request letter, exam or complaint behaves like an unreported claim. It exists in fact, is estimable from the deficiency-rate data, and has simply not yet arrived through an enforcement channel. The accounting sits under ASC 450 as a contingent liability rather than IBNR proper, but estimating an unreported liability from a known reporting lag is work health actuaries already do.

Retroactivity is what makes it live. Georgia's January 2026 fines of nearly $25 million across 11 insurers, led by $10.2 million against Oscar Health Plan of Georgia and $4.6 million against Blue Cross Blue Shield Healthcare Plan of Georgia, came out of market conduct examinations of calendar year 2022. If the December 2026 rule restores a version of the meaningful-benefit standard and examiners then review plan years 2025 through 2027 against it, the exposure accruing now does not vanish because enforcement was paused while those years were lived.

Two NQTLs carry most of that risk, and both are pricing assumptions. Enforcement concentrates on network adequacy and composition, and on the reimbursement methodology setting out-of-network rates for behavioral health providers. A plan whose own claims show materially higher out-of-network utilization for behavioral health than for medical and surgical services has to show the gap is not a thinner network or a lower relative reimbursement schedule. A carrier pricing to that reimbursement gap, even on ordinary specialty-mix grounds, is pricing to the methodology regulators have flagged as likeliest to fail.

The Pause Is Not National

State commissioners keep independent enforcement authority over fully insured business, and several have moved to hold the 2024 standard whatever Washington does with it. Washington state enacted legislation requiring compliance with the 2024 federal rule as published, so a later federal rescission does not loosen the state standard. Colorado's HB 25-1002 requires nationally recognized clinical criteria for behavioral health coverage decisions on its own timeline. Georgia is enforcing its own parity statute and has not paused.

So a single national exposure estimate is wrong in both directions at once. In Washington and Colorado the meaningful-benefit and certification standards are live obligations today and a book priced to the federal pause is under-reserved. In states with no independent statute the relaxed 2013-era standard genuinely applies until the new rule lands, and the same estimate overstates the liability.

The Georgia record adds a second caution about sizing. An 11Alive investigation found that months after the fines were announced, none of the $25 million had been collected. A headline penalty and a realized cash liability are different quantities, and a remediation reserve built off announced fines in one state inherits a collection assumption nobody has tested.
