Mental health parity remains an important compliance and reimbursement issue for behavioral health providers in 2026. The regulatory landscape has received additional clarification this year, particularly regarding how federal agencies are enforcing the Mental Health Parity and Addiction Equity Act (MHPAEA).
On September 8, 2026, the U.S. Department of Labor (DOL) issued Field Assistance Bulletin 2026-03 explaining the Employee Benefits Security Administration’s (EBSA) current approach to MHPAEA enforcement. EBSA is not currently enforcing portions of the 2024 MHPAEA Final Rule that are new compared with the 2013 regulations. However, the underlying MHPAEA statute and applicable requirements added by the Consolidated Appropriations Act, 2021 (CAA 2021), including NQTL comparative-analysis requirements, continue to apply.
The bulletin is an internal EBSA enforcement policy. It does not itself create enforceable substantive or procedural rights, but it provides insight into the agency’s current enforcement priorities.
What Is Mental Health Parity?
MHPAEA generally prevents applicable health plans and insurers from applying more restrictive requirements to mental health and substance use disorder (MH/SUD) benefits than to comparable medical and surgical benefits.
A key part of parity compliance involves Nonquantitative Treatment Limitations (NQTLs). These are restrictions that are not primarily expressed as numerical limits.
Examples include:
- Prior authorization
- Medical necessity reviews
- Utilization management
- Concurrent and retrospective review
- Network participation requirements
- Provider admission standards
- Provider reimbursement methodologies
An NQTL is not automatically a parity violation. The relevant analysis considers whether the processes, strategies, evidentiary standards, and other factors applied to MH/SUD benefits are comparable to and no more stringent than those applied to comparable medical and surgical benefits.
What Changed for MHPAEA in 2026?
The 2024 MHPAEA Final Rule introduced additional requirements involving areas such as meaningful benefits, data evaluation, discriminatory factors and evidentiary standards, and NQTL comparative analyses.
However, DOL’s September 2026 guidance states that EBSA will not pursue enforcement of portions of the 2024 Final Rule that are new compared with the 2013 regulations. At the same time, EBSA continues enforcement of statutory MHPAEA requirements, including the CAA 2021 requirements concerning NQTL comparative analyses.
For behavioral health practices, this means parity protections remain relevant even though the enforcement approach has changed.
Three MHPAEA Areas DOL Is Prioritizing
The September 2026 DOL/EBSA guidance identifies three areas for NQTL enforcement focus.
1. Separate Treatment Limitations and Exclusions
EBSA will focus on separate treatment limitations and exclusions, including certain blanket exclusions that apply to MH/SUD benefits when comparable treatments are covered for medical or surgical conditions.
2. Medical Necessity and Review Processes
Medical necessity standards and review processes are another priority. This includes prior authorization, concurrent review, and retrospective review.
Behavioral health practices should monitor authorization requirements, turnaround times, documentation requests, denial reasons, and payer review patterns.
3. Network Adequacy and Reimbursement
EBSA is also focusing on network adequacy, network admission standards, and provider reimbursement methodologies.
For providers, network participation requirements and reimbursement policies can directly affect access to behavioral health services and revenue cycle performance.
How Mental Health Parity Affects Behavioral Health Billing
Mental health parity can intersect with several areas of behavioral health billing and revenue cycle management.
Prior authorization: Practices should track authorization requests, approval rates, delays, additional documentation requests, and authorization-related denials.
Medical necessity: Providers should maintain complete clinical documentation and review recurring medical necessity denial patterns.
Claim denials: When a denial raises a potential parity concern, the appeal should identify the specific denial reason, relevant documentation, payer policy, and the comparable medical or surgical requirement being evaluated.
Network and reimbursement issues: Practices should document payer requirements and review network admission and reimbursement policies when potential parity concerns arise.
Practical Steps for Behavioral Health Practices
Behavioral health organizations can strengthen their compliance and billing workflows by:
- Monitoring denial trends by payer, service type, authorization status, and denial reason.
- Tracking prior authorization performance, including approval rates, turnaround times, and documentation requirements.
- Documenting potential NQTL differences and comparing the relevant behavioral health requirement with the applicable medical or surgical requirement.
- Maintaining payer documentation, including policies, denial letters, authorization requirements, and reimbursement information.
- Reviewing the applicable coverage type, since requirements and enforcement pathways can differ among commercial, self-funded, Medicaid managed care, and other coverage arrangements.
Frequently Asked Questions
Is mental health parity suspended in 2026?
No. MHPAEA remains in effect. EBSA is not currently enforcing portions of the 2024 Final Rule that are new compared with the 2013 regulations, while statutory MHPAEA requirements and applicable CAA 2021 requirements continue to apply.
Does MHPAEA apply to prior authorization?
Yes. MHPAEA does not prohibit prior authorization, but when prior authorization is used as an NQTL, applicable plans and issuers must evaluate whether its processes and standards are comparable to and no more stringent for MH/SUD benefits than for comparable medical and surgical benefits. EBSA specifically identifies prior authorization as an enforcement focus.
Can behavioral health providers raise parity concerns about denials?
Providers can identify and document potential parity concerns during denial reviews and appeals, subject to the applicable plan terms, payer requirements, contractual arrangements, and legal framework.
