Medicare Opioid Treatment Programs

Key takeaway

Medicare Part B can pay an enrolled opioid treatment program a bundle for opioid use disorder care, including methadone, counseling, and testing. You do not owe a copay at that program. The Part B deductible still applies. This is not residential alcohol rehab, and it is not a decision about Medicaid.

Medicare is not Medicaid, and an opioid treatment program is not a residential alcohol rehab. People often ask both questions in the same breath. The Medicaid rules, including which addiction services a state must cover, are on the Medicaid guide. This page is the Medicare benefit for opioid use disorder treatment at an opioid treatment program, often called an OTP.

What Medicare will pay an enrolled program to do

CMS says opioid treatment programs provide medications for opioid use disorder. To be an OTP they must be certified by SAMHSA and accredited by an independent body that SAMHSA approves. Medicare pays those programs through bundled payments for people on Part B.

The CMS page, marked last modified on March 10, 2026, says the OTP benefit can include:

FDA-approved opioid agonist and antagonist medications
Dispensing and administering those medications, if that applies
Substance use counseling
Individual and group therapy
Toxicology testing
Intake and periodic assessments
Intensive outpatient services
Coordinated care and referral services
Patient navigation
Peer recovery support

The same page says programs dispense and administer methadone, buprenorphine in oral, injectable, and implantable forms, naltrexone, and the overdose-reversal drugs naloxone and nalmefene. When a program gives take-home naloxone or nalmefene, it also provides overdose education. Counseling and therapy can be done by two-way audio-video. Some of these services can be furnished from a mobile van. Medicare Advantage members and people who have both Medicare and Medicaid can get OTP services.

42 CFR 410.67 is the rule behind the bundle. It dates the benefit to an episode of care that begins on or after January 1, 2020. The bundle that includes a medication has a drug piece and a non-drug piece. The non-drug piece covers dispensing or administration, counseling, individual and group therapy, and toxicology testing, among the other services in the patient's plan. At least one of the core treatment services has to be furnished before the program can bill the episode. This page will not turn that sentence into a billing code.

CMS says the non-drug part of the payment is adjusted for geographic location, so the dollar amount changes with the program's ZIP code. The agency posts yearly rate files, including a 2026 file. Those files are for billers. This page does not print a rate, and a national average would be the wrong number for your county.

Which part of Medicare pays for which medicine

Medicare.gov splits the same medicines by setting.

Part A, the hospital benefit, covers methadone, buprenorphine, and naltrexone when you receive them as an inpatient in the hospital.

Part B covers methadone, buprenorphine, and naltrexone when you get them in a doctor's office or through an opioid treatment program. Part B also covers nalmefene and naloxone to reverse an opioid overdose.

Part D, the drug plan, may cover buprenorphine and naltrexone, and drugs that reverse an overdose, such as nalmefene and naloxone. The page says to contact your plan. It does not put methadone on that Part D list. Methadone for opioid use disorder, in this benefit, is the Part A hospital path or the Part B office and OTP path.

Medicare.gov also describes care from a doctor who is not an OTP: overall care management, individual and group therapy, more counseling, and in some cases buprenorphine or naltrexone. It says you may be able to start buprenorphine without an in-person exam if the clinician can evaluate you by audio and video, or by audio only. Other medications may still require an in-person exam. That is a coverage description. It is not a reason to start medicine from a text message. The medication FAQ explains why doses and the wait before naltrexone belong to a prescriber.

The program must be enrolled in Medicare. A SAMHSA-certified OTP that has not enrolled cannot bill this benefit, even if it is a legal clinic for other payers. Ask "Are you enrolled in Medicare?" and ask which of the services above you would actually receive.

What you may owe

Medicare.gov is specific about cost sharing, and it still refuses to name your bill.

If the services come from an opioid treatment program that is enrolled in Medicare and meets the other requirements, you will not pay a copayment. The Part B deductible applies to the services, including supplies and medications you get as part of the treatment. CMS's billing page says the same thing: no copayment for OTP services, and the Part B deductible applies.

If the services come from a doctor or other health care provider, you pay copayments and the Part B deductible.

If you have both Medicare and Medicaid, you pay nothing for the services you get through your state Medicaid program. That sentence is about the Medicaid side of dual coverage. It is not a finding that every OTP service is billed to Medicaid, and the Medicaid guide is why state benefits still vary.

People who have been diagnosed with opioid use disorder can receive the treatment services for as long as they are reasonable and necessary. "Reasonable and necessary" is Medicare's standard. It is not a number of weeks this page can promise. Your other insurance, whether the clinician accepts assignment, and the type of facility change what you owe. Ask before you travel.

What this page is not

A weekly OTP bundle is not a residential alcohol program, not a hospital detox for alcohol, and not a sober house. The one-paragraph description of Medicare's broader behavioral-health coverage, including inpatient Part A and outpatient Part B, is on the no-insurance cost guide. Use that page for the wider map. Use this one when the question is methadone, buprenorphine, or naltrexone under Medicare.

Naloxone and nalmefene in the bundle do not replace 911. If breathing is slow or the person will not wake, call 911 and use naloxone if you have it. The overdose guide is the emergency steps.

SmarterRecovery is a referral helpline. It is not Medicare, not an opioid treatment program, and not SMART Recovery, the separate peer program. The about page says calling is free and that treatment providers pay for the referral service. A referral call can check benefits before you commit. That check is not a Medicare determination and not a bill.

Call (800) 653-9376 if you have Medicare and need help finding opioid use disorder treatment. Ask the program whether it is enrolled in Medicare and what you would owe toward the deductible. Call SAMHSA's National Helpline at 1-800-662-HELP (4357) for the federal referral line. Call 911 for slowed breathing, a seizure, or collapse. Call or text 988 in a mental health crisis.

Common Questions

Does Medicare pay for methadone?

Medicare.gov says Part A covers methadone, buprenorphine, and naltrexone when you get them as a hospital inpatient. Part B covers those three medicines in a doctor's office or through an opioid treatment program. The Part D sentence on that page lists buprenorphine, naltrexone, and overdose-reversal drugs, and it tells you to ask the plan. It does not list methadone under Part D. Do not assume the pharmacy counter is the methadone benefit.

What does the opioid treatment program bundle include?

CMS says Medicare pays enrolled programs a bundle that can include the FDA-approved medicines, dispensing, substance use counseling, individual and group therapy, toxicology testing, intake, periodic assessments, intensive outpatient services, coordinated care and referrals, patient navigation, and peer recovery support. Overdose-reversal medicine and education can be part of the benefit. Counseling may be by two-way audio and video. The list is what the benefit can cover. It is not a menu you are guaranteed this week.

Will I owe a copay?

Medicare.gov says that if you get these services from an opioid treatment program enrolled in Medicare, you will not owe a copay. The Part B deductible still applies. If you get the services from a doctor or other practitioner instead, you pay copayments and the Part B deductible. If you have both Medicare and Medicaid, Medicaid may cover your share. A deductible is not a copay. Ask what you have already met this year.

Does this cover a residential alcohol program?

No. This page is the opioid treatment program benefit. Payment has to be for treatment of opioid use disorder. A residential alcohol stay is a different question. Medicare.gov's broader behavioral-health page is summarized on the guide to rehab cost without insurance. Read your own Medicare materials before you travel for alcohol treatment. This page will not invent a room rate.

How long can the treatment last?

Medicare.gov says people who have been diagnosed with opioid use disorder can get the treatment services for as long as they are reasonable and necessary. That is a coverage standard, not a personal treatment plan, and it is not a promise that every extra week will be paid. The program has to be enrolled in Medicare. A referral call can check benefits before you commit. That check is not Medicare's decision.
