What Is Mental Health Parity?
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires group health plans that cover mental health and substance use disorder (MH/SUD) treatment to cover it comparably to medical and surgical care — no higher costs, no tighter limits, no harder path to getting care.
Where the Rules Stand Right Now
- The statute is in force and being enforced. MHPAEA’s requirements, as amended by the Consolidated Appropriations Act of 2021, apply today. That includes the obligation for plans to maintain a written comparative analysis of their nonquantitative treatment limitations (NQTLs) — things like prior authorization, network adequacy standards, and reimbursement methodology. The Department of Labor and CMS continue to issue document requests and noncompliance findings in this area.
- The 2024 final rule is on hold. In September 2024, federal agencies finalized a rule adding detailed new parity requirements. That rule was challenged in court, and in May 2025 the Departments announced they would not enforce the provisions that were new relative to the earlier 2013 rule. That pause runs until the litigation concludes, plus 18 months.
New rules are coming. The Departments have said they plan to issue a revised proposed rule rather than defend the 2024 version. Expect a new proposal and another round of comment before anything takes effect.
Last reviewed: 2026. Parity rules are actively changing — we update this page as new guidance is issued.
Why It Matters for Your Organization
- Compliance. Parity obligations rest with your health plan. Even with the 2024 rule paused, the underlying statutory requirements — including comparative analyses — are live and subject to audit.
- Employee well-being. Employees with real access to mental health support are more engaged and miss less work.
- Cost management. Addressing mental health concerns early is cheaper than treating them after they escalate.
- Recruiting. A serious mental health benefit signals that you take employee well-being seriously.
