The "Parity Enforcement Act of 2025" aims to strengthen the enforcement of mental health and substance use disorder parity requirements by introducing civil monetary penalties for violations. This legislation specifically amends the Employee Retirement Income Security Act of 1974 (ERISA) , expanding the scope of entities subject to penalties. Under the proposed changes, not only plan sponsors but also service providers and plan administrators of group health plans could face financial penalties for failing to comply with mental health parity mandates. The bill explicitly adds violations of mental health and substance use disorder parity benefits under section 712(a) of ERISA as grounds for these new penalties. Furthermore, it modifies ERISA's enforcement provisions to enable the Secretary to levy these civil monetary penalties, with the changes taking effect for plan years beginning one year after the bill's enactment.
