State Medicaid Agencies Navigate Mental Health Parity Enforcement Amid Federal Uncertainty

This white paper examines how state Medicaid agencies can strengthen enforcement of mental health parity requirements for managed care entities, even as federal priorities shift following the 2025 suspension of certain commercial market rules. The analysis walks through the three types of treatment limitations under MHPAEA—financial requirements, quantitative limits, and nonquantitative treatment limitations—and emphasizes that existing Medicaid parity obligations remain in effect regardless of federal enforcement changes. For MCO compliance teams and state Medicaid directors, this offers a roadmap for improving oversight of behavioral health access in managed care programs, which collectively represent the largest payer for mental health and substance use disorder services.
