On February 20, 2025, the ERISA Industry Committee (ERIC) announced that its legal counsel submitted a letter to the U.S. Departments of Labor (DOL), Health and Human Services (HHS) and Treasury, requesting a stay of enforcement of the September 2024 Mental Health Parity and Addiction Equity Act (MHPAEA) Final Rule. In the letter, ERIC urged the Departments to exercise their authority under 5 U.S.C. § 705 to postpone the effective date of the Final Rule while litigation challenging its validity is ongoing. This request marks a significant development in the legal landscape surrounding mental health parity laws and could have far-reaching implications for employers, health plans, and other stakeholders in the health insurance industry.
