Yes: since January 1, 2020, Medicare Part B has covered treatment for opioid use disorder as a single bundled benefit, and the medication itself is part of it. So if you've heard that Medicare won't pay for opioid treatment, or that methadone is off the table on Medicare, that's outdated. The medication, the counseling, the therapy, drug testing, and your intake visit all sit under one Part B benefit when you get care at a Medicare-enrolled Opioid Treatment Program (OTP).

What Medicare Covers for Opioid Treatment

For years there was a real gap here: Medicare paid for a lot of care, but not for the day-to-day services of an opioid treatment clinic. That changed on January 1, 2020, when Part B added a benefit category built specifically for opioid use disorder treatment delivered at an OTP.

The key thing to understand is that it's a bundle, not a menu of separate charges. When you get care at a Medicare-enrolled OTP, Part B covers the whole package of services as one benefit. That package includes:

  • The FDA-approved medications used to treat opioid use disorder, plus dispensing and administering them
  • Substance use counseling
  • Individual and group therapy
  • Toxicology (drug) testing
  • Intake activities, including your first medical examination
  • Periodic assessments as your treatment continues

Behind the scenes, Medicare pays the program a single bundled amount for a week of care rather than itemizing each service. You don't have to track any of that. What it means for you is that the counseling session, the therapy group, and the medication aren't billed as separate line items you piece together yourself; they're one covered benefit.

An OTP is a specific kind of facility. These clinics are certified by the Substance Abuse and Mental Health Services Administration (SAMHSA), and that certification is what qualifies them to dispense opioid treatment medications. For Medicare to cover your care, the program also has to be enrolled in Medicare, so it's worth confirming a clinic is Medicare-enrolled before you start.

Does Medicare Cover Methadone, Buprenorphine, and Naltrexone?

Yes. All three of the main FDA-approved medications for opioid use disorder are covered under this Part B benefit when they're furnished at an OTP: methadone, buprenorphine, and naltrexone, in their oral, injected, or implanted forms.

Methadone works differently from the other two. For opioid use disorder, it can't be picked up at a regular pharmacy or prescribed in a doctor's office; federal rules require it to be dispensed only through an OTP. So before 2020, a Medicare beneficiary had a hard time getting methadone treatment covered at all. Now the OTP benefit covers it directly, along with the counseling and testing that go with it.

This coverage runs through Part B and the OTP, not through your Part D drug plan. Part D may still cover certain opioid use disorder medications you fill at a retail pharmacy, but the bundled OTP services described here, the methadone included, are a Part B benefit.

Who Qualifies for the OTP Benefit

The benefit is for people who have Medicare Part B and are being treated for opioid use disorder at an OTP. In plain terms, if you're enrolled in Part B and a Medicare-enrolled opioid treatment program is treating you, you're in the group this covers.

A few situational notes are worth knowing:

What Opioid Treatment Costs When Medicare Covers It

The cost has two parts: what you pay per visit, and the deductible.

Your copay and coinsurance for OTP services are $0. Get your care from an OTP that's enrolled in Medicare and meets the requirements, and you won't owe a copayment for the covered services.

The annual Part B deductible still applies first, though. In 2026 that deductible is $283, and Medicare's own guidance is clear that it applies to these services, including any supplies and medications you get as part of treatment., So the accurate way to say it is: $0 in copays or coinsurance, but you pay toward the $283 deductible first if you haven't already met it for the year through other Part B care.

Two exceptions push that cost even lower. If you have both Medicare and Medicaid and get the services through your state Medicaid program, you pay nothing at all. And if you're in a Medicare Advantage plan, the cost is whatever your plan sets, so confirm it with them rather than assuming.

If you're weighing whether treatment is affordable, that's the honest picture: not literally free from the first dollar, but close, with no per-visit copay standing between you and care.

Frequently Asked Questions

Does Medicare cover opioid addiction treatment?

Yes. Medicare Part B has covered it since January 1, 2020, as one bundled benefit delivered at a Medicare-enrolled Opioid Treatment Program (OTP).

Does Medicare pay for methadone?

Yes, when it's furnished through a Medicare-enrolled OTP. Methadone for opioid use disorder has to be dispensed through an OTP under federal rules, and the Part B OTP benefit covers it, along with buprenorphine and naltrexone, together with the counseling and testing that come with treatment.

How much does opioid treatment cost with Medicare?

Your copay and coinsurance for OTP services are $0. You do have to meet the annual Part B deductible first, which is $283 in 2026. If you have both Medicare and Medicaid and get care through your state Medicaid program, you pay nothing; Medicare Advantage members should check their plan.

Is this covered by Part B or Part D?

The bundled OTP services, including the methadone, are a Part B benefit, not Part D. Your Part D drug plan may still cover certain opioid use disorder medications filled at a retail pharmacy, but the clinic-based OTP bundle runs through Part B.

How do I find a Medicare-enrolled opioid treatment program?

Look for an OTP that is both certified by SAMHSA and enrolled in Medicare, since Medicare only covers the benefit at an enrolled program. It's worth calling the clinic to confirm its Medicare enrollment before your first visit.
