An Act to further define medical necessity determinations

This bill amends state laws to clarify definitions and coverage rules for specific mental health services for Commonwealth employees. It establishes clear time limits for insurance coverage of inpatient treatment, crisis stabilization, and community-based care without requiring pre-authorization. Under the new rules, doctors and patients jointly determine if care is medically necessary, while insurance companies can review cases after a set number of days. The legislation directly affects active and retired state employees who have access to group health insurance plans.
