Agencies Say They Won't Enforce 2024 Mental Health Parity Final Rule

AHA News reported that federal agencies announced they will not enforce the 2024 Mental Health Parity Final Rule, effectively shifting enforcement responsibility to states and creating significant regulatory uncertainty for both insurers and providers. For physician practices that provide or refer for behavioral health services, this enforcement pause has immediate practical implications — and the shift to state-level enforcement creates a patchwork that practices must navigate carefully.

The 2024 Mental Health Parity Final Rule was designed to strengthen the requirements of the Mental Health Parity and Addiction Equity Act by requiring insurers to conduct detailed comparative analyses of their non-quantitative treatment limitations for behavioral health versus medical/surgical services. The federal enforcement pause means that these comparative analysis requirements will not be enforced at the federal level for the foreseeable future.

What the Enforcement Pause Means

The practical effect of the enforcement pause is that insurers face reduced federal pressure to comply with the most stringent parity requirements. Without federal enforcement of the NQTL comparative analysis requirements, payers may have less incentive to eliminate the prior authorization, medical necessity criteria, and network adequacy disparities that the rule was designed to address.

For physician practices, this could mean:

• Continued or expanded PA requirements for behavioral health services that do not apply to comparable medical services
• Medical necessity criteria for behavioral health that remain more restrictive than for medical/surgical services
• Network adequacy gaps that force behavioral health patients to seek out-of-network care at higher cost
• Denial rates for behavioral health claims that remain elevated relative to medical/surgical claims

In short, the enforcement pause removes a tool that was expected to compel insurers to reduce behavioral health coverage disparities. The disparities themselves do not go away — they simply face less regulatory pressure to change.

The Shift to State Enforcement

The enforcement pause does not eliminate parity enforcement entirely — it shifts primary enforcement responsibility to states. This is significant because state parity enforcement capacity varies enormously. Some states have invested heavily in parity enforcement infrastructure, including dedicated enforcement units, mandatory insurer reporting, and substantial fine authority. Other states have minimal parity enforcement capacity.

For physician practices, the relevant question is: how strong is parity enforcement in my state? Practices in states with robust enforcement may see continued or even increased pressure on payers to comply with parity requirements. Practices in states with weaker enforcement may see payers become less responsive to parity-based denial challenges.

States that have been particularly active in parity enforcement include New York, California, Georgia, and Washington — states that have collectively levied tens of millions of dollars in parity violation fines. Practices in these and similarly active states can continue to leverage parity arguments in appeals and regulatory complaints with confidence.

Practical Response for Physician Practices

The federal enforcement pause does not change the fundamental law. The Mental Health Parity and Addiction Equity Act remains in effect. Insurers are still legally required to provide parity between behavioral health and medical/surgical coverage. What has changed is the likelihood of federal enforcement of specific compliance requirements.

Practices should continue to:

• Incorporate parity arguments into appeals for behavioral health denials when applicable
• File regulatory complaints with state insurance commissioners when denial patterns suggest parity violations
• Track behavioral health denial rates separately to identify disparities
• Stay informed about their state's parity enforcement activity and capacity

Practices should also be aware that the enforcement pause may be temporary. Federal enforcement priorities can shift with changes in administration, congressional pressure, or public attention. Building parity-aware denial management processes now positions practices to benefit from enforcement regardless of when and where it occurs.

The Advocacy Angle

The enforcement pause reinforces the importance of physician advocacy at the state level. When federal enforcement retreats, state-level action becomes the primary mechanism for parity accountability. Physician practices and their professional associations have a direct interest in supporting strong state parity enforcement — both through legislative advocacy and through the filing of regulatory complaints that provide the data regulators need to act.

The pause is a setback for parity enforcement, but not an end. State-level enforcement continues, the underlying law remains in effect, and the data practices collect on behavioral health denials retains its value for appeals, complaints, and advocacy.
