An Act related to comprehensive clinical and extended support services

This bill defines "transitional support services" as short-term residential care following clinical stabilization for addiction recovery, and requires insurers to cover medically necessary acute treatment, clinical stabilization, and transitional support services without preauthorization. It applies directly to Commonwealth employees (active/retired) under group insurance, Medicaid managed care plans, and private insurers offering "creditable coverage" under Chapter 111M. Key provisions include a 30-day coverage limit for transitional services, 48-hour facility notification to insurers after admission, and restrictions on utilization reviews (which can only begin after day 14 and cannot deny future care without 30 consecutive days of service). Medical necessity is determined by treating clinicians, not insurers, with coverage mandated for substance use disorder evaluations under Section 51½ of Chapter 111.
