An Act to further define medical necessity determinations

H 4894 defines specific mental health treatment services - including acute inpatient care, crisis stabilization, and community-based options for children and adults - and eliminates preauthorization requirements for coverage. It directly affects Commonwealth employees (active and retired) under Group Insurance Commission plans and Medicaid beneficiaries. The bill mandates that facilities notify insurers within 48 hours of admission for all services, with utilization review permitted to begin after 7-10 days, while requiring medical necessity to be determined by the treating clinician and documented in the patient’s record. This streamlines access to critical mental health care by reducing administrative barriers for defined services.
