IMD exclusion
Also written as: IMD — Institution for Mental Disease
Federal Medicaid restriction limiting payment for services in institutions for mental diseases with over 16 beds.
Full Definition
The IMD exclusion is a longstanding federal Medicaid policy that prohibits payment for services provided to most beneficiaries aged 21-64 in institutions for mental diseases (IMDs) with more than 16 beds. This exclusion significantly impacts psychiatric hospitals and large residential treatment facilities, creating coverage gaps and influencing treatment settings and discharge planning decisions. Some states have obtained waivers to provide limited IMD coverage for substance use disorder treatment, and recent federal initiatives have explored modifications to this policy.
Usage
Usage note: Critical for understanding reimbursement limitations in psychiatric facilities.
