Detailed Medicare coverage analysis
Medicare coverage structure for SUD
Medicare provides comprehensive addiction treatment coverage across its parts: Part A (hospital insurance) covers inpatient detox and hospital-based residential treatment up to 90 days per benefit period; Part B (medical insurance) covers outpatient services including therapy, group counseling, intensive outpatient (IOP), partial hospitalization (PHP), and some MAT medications administered in clinical settings; Part D (prescription drug coverage) covers Suboxone, naltrexone, and other oral MAT medications via pharmacy benefit; Medicare Advantage (Part C) plans bundle A/B/D coverage with often enhanced behavioral health benefits.
SUPPORT Act 2022 expansion
The 2022 SUPPORT Act significantly expanded Medicare SUD coverage. Key additions: Opioid treatment programs (OTPs) now Medicare-certified — methadone covered as Part B medical benefit at $0 patient cost; Coverage for opioid use disorder treatment in office-based settings including bundled payments for prescriber visits; Telehealth expansion for behavioral health including SUD treatment; Mobile units and home-based SUD treatment coverage in some pilot regions.
MAT coverage across Medicare parts
All FDA-approved MOUD covered under Medicare: Methadone via OTP clinics covered under Part B medical benefit (no patient cost-sharing per SUPPORT Act). Buprenorphine covered under Part D pharmacy benefit ($5-$50 copay typical for generic; higher for brand Suboxone film). Naltrexone (oral) covered under Part D ($5-$25 copay). Vivitrol (extended-release naltrexone injection) covered under Part B medical benefit. Sublocade (extended-release buprenorphine) covered under Part B with prior authorization typical.
Cost-sharing reality (2024 figures, indexed annually)
Part A inpatient: $1,632 deductible per benefit period (benefit periods reset after 60 consecutive days out of hospital). Days 1-60: $0 coinsurance. Days 61-90: $408/day. Days 91+: $816/day (lifetime reserve days). Part B outpatient: $240 annual deductible (2024), then 20% coinsurance. Part D: varies by plan and tier — generic buprenorphine typically $5-$25 copay. Medicare Advantage: varies significantly by plan; many MA plans have $0-$300 inpatient copays and $0-$25 outpatient mental health copays — often better than Original Medicare for SUD.
Medigap and Medicare Advantage for SUD
Original Medicare alone has no annual out-of-pocket maximum — for someone with extended SUD treatment, costs can accumulate without cap. Two solutions: Medigap (Medicare Supplement) plans cover Part A/B coinsurance and deductibles (Plan G most popular — covers 100% of Medicare-covered costs after Part B deductible). Medicare Advantage plans have legally required annual OOP max ($8,850 in-network for 2024, indexed). For Medicare-eligible patients with active SUD, MA or Medigap supplemental coverage substantially reduces OOP exposure.
What Does Medicare Cover for Addiction Treatment?
Medicare provides coverage for substance use disorder treatment as part of its behavioral health benefits. Under federal law — specifically the Mental Health Parity and Addiction Equity Act (MHPAEA) and the Affordable Care Act — Medicare is required to cover addiction treatment at the same level as other medical conditions.
This means your Medicare plan covers multiple levels of care, from initial detox through long-term outpatient support. The specific costs, referral requirements, and network restrictions depend on your plan type — see the plan comparison below.
At RehabHive, we work with Medicare daily and can verify your specific benefits in under 5 minutes. We will tell you exactly what is covered, what your out-of-pocket costs will be, and which treatment centers near you accept your plan.

Your Rights with Medicare
Mental Health Parity Act
Medicare must cover addiction treatment at the same level as physical health conditions. They cannot impose higher copays, stricter visit limits, or more restrictive pre-authorization for rehab.
Right to Appeal
If Medicare denies your claim, you have the legal right to appeal. Request a written explanation and file a formal appeal. Many denials are overturned — especially with supporting documentation from your treatment provider.
