Medicare Rehab Coverage Guide
Navigate Medicare's addiction treatment benefits. Understand Part A, Part B, Medicare Advantage options, and your out-of-pocket costs.
Medicare Addiction Treatment Coverage Overview
Medicare is the federal health insurance program serving over 65 million Americans aged 65 and older, as well as younger people with certain disabilities. Medicare provides comprehensive coverage for substance use disorder treatment, though understanding how the different parts of Medicare work together is essential for maximizing your benefits and minimizing out-of-pocket costs.
Medicare coverage for addiction treatment is divided between Part A (Hospital Insurance) and Part B (Medical Insurance). Part A covers inpatient hospital-based treatment including medical detox and residential rehabilitation in hospital settings. Part B covers outpatient services including therapy, intensive outpatient programs (IOP), partial hospitalization programs (PHP), and medication-assisted treatment services. Additionally, Part D provides prescription drug coverage that includes medications used in addiction treatment.
For many Medicare beneficiaries, especially those with ongoing healthcare needs, Medicare Advantage (Part C) plans offer an attractive alternative to Original Medicare. These private plans combine Part A and Part B benefits and often include Part D prescription coverage, with the added benefit of an annual out-of-pocket maximum—something Original Medicare does not provide.
