An Act relative to dual diagnosis treatment coverage

This bill expands health insurance coverage in Massachusetts to include specific addiction treatments for individuals with co-occurring mental health and substance use disorders. It mandates that both state employee insurance plans and Medicaid programs cover acute detoxification, clinical stabilization, and inpatient psychiatric services for up to 14 days without requiring pre-approval. The legislation defines these services as medically necessary care provided in licensed facilities and allows for utilization reviews to begin on the seventh day of treatment. By removing preauthorization barriers, the bill aims to ensure faster access to critical care for patients admitted to these programs.
