An Act relative to dual diagnosis treatment coverage

This bill expands insurance coverage in Massachusetts for individuals with co-occurring substance use and mental health disorders by removing preauthorization requirements for specific inpatient treatments. It mandates that both state employee health plans and Medicaid programs cover acute detoxification, clinical stabilization, and co-occurring psychiatric treatment for up to 14 days without prior approval. The legislation requires facilities to notify insurance carriers within 48 hours of admission and allows utilization review to begin on the seventh day, ensuring timely access to care while maintaining oversight.
