Follow Mental Health Parity Rulemaking (R 2025-13).
E2SHB 1432 updates Washington's mental health parity law and ensures coverage of medically necessary care. It requires utilization and clinical review criteria to be consistent with generally accepted standards of mental health and substance use care, and incorporates the final federal rules related to the federal Mental Health Parity and Addiction Equity Act (MHPAEA), adopted in September 2024, into Washington state law.
Mental health parity
State and federal mental health parity laws require that insurance coverage for mental health conditions, including substance use disorders, be no more restrictive than insurance coverage for other medical conditions.
