Medicare covers some alcohol addiction treatment, but what it pays for depends on the type of care and your specific plan

Medicare Part B covers outpatient counseling and behavioral therapy for alcohol use disorder at 80% of the approved cost after you meet your deductible. Medicare Part A covers inpatient rehabilitation stays in hospitals and certified rehabilitation facilities — places that specialize in addiction treatment — as long as a doctor orders the care and the facility accepts Medicare. The amount you pay depends on how long you stay and whether you have supplemental insurance.

What Medicare does not cover: detoxification in a standard hospital emergency department is covered, but residential treatment centers that are not certified rehabilitation facilities are not. Outpatient programs at non-hospital clinics may be covered under Part B if they are run by a physician or licensed mental health professional, but coverage varies by plan. Always check with your plan before starting treatment, because some Medicare Advantage plans have different rules than Original Medicare.

Key Takeaways

  • Original Medicare Part A covers inpatient rehab stays in certified facilities after a doctor's referral, and Part B covers outpatient counseling at 80% after your deductible.
  • You pay a copay for each outpatient visit and a daily copay for inpatient stays, with limits on how many days Medicare will fund.
  • Residential treatment centers that are not hospital-based or certified rehabilitation facilities are not covered by Medicare.
  • Medicare Advantage plans may cover different services or require prior approval, so contact your plan before you start treatment.
  • Your doctor must refer you for inpatient care, and the facility must accept Medicare for the coverage to explore.

How Medicare Part A covers inpatient rehab

If you need to stay overnight in a rehabilitation facility for alcohol addiction treatment, Medicare Part A covers the cost of the facility, meals, and basic care. The facility must be a Medicare-certified rehabilitation facility — usually a hospital with a dedicated addiction treatment unit or a standalone rehab center that meets Medicare standards. Your doctor must order the admission and document that you need 24-hour medical supervision.

You pay a daily copay for each day of your stay. In 2024, that copay is $194.50 per day for days 1 through 60, and $389 per day for days 61 through 90. Medicare covers up to 90 days per benefit period for rehabilitation, though most stays are shorter. After 90 days, you pay the full cost yourself unless you have supplemental insurance.

The facility handles billing directly to Medicare, so you do not pay upfront. However, you are responsible for the daily copay, and you should ask the facility in advance what their total charges are, because you may owe the difference between what Medicare approves and what the facility charges if they do not accept Medicare's approved amount as payment in full.

How Medicare Part B covers outpatient counseling and therapy

Outpatient addiction counseling and behavioral therapy are covered under Medicare Part B when provided by a doctor, psychiatrist, psychologist, clinical social worker, or licensed professional counselor. You pay 20% of the approved cost after you meet your annual Part B deductible (which is $240 in 2024). Each visit typically costs between $30 and $60 out of pocket, depending on the provider and your deductible status.

Coverage includes individual therapy, group counseling, and cognitive behavioral therapy (CBT) specifically for alcohol use disorder. Some outpatient programs at hospitals or community mental health centers are covered if they bill as a physician service. However, if the program is run by a non-physician facility — such as a private addiction treatment center without a medical director — Medicare may not cover it, or coverage may be limited.

You do not need a referral from your primary care doctor to see a therapist or counselor covered under Part B, but your provider must accept Medicare assignment. Always ask the provider's office whether they accept Medicare and what your out-of-pocket cost will be before your first visit.

What Medicare does not cover for alcohol treatment

Medicare does not cover residential treatment centers unless they are certified as rehabilitation facilities. Many private addiction treatment centers are residential but not hospital-based, and Medicare will not pay for stays at these facilities. If you want to use Medicare to pay for a residential program, you must choose a facility that is either a hospital with an inpatient addiction unit or a Medicare-certified rehabilitation facility.

Medications used to treat alcohol use disorder — such as naltrexone, acamprosate, or disulfiram — are covered under Medicare Part D (prescription drug coverage) if your plan includes them, but you pay your plan's copay or coinsurance. Some medications may require prior approval from your plan before the pharmacy will fill them.

Detoxification in a hospital emergency department is covered under Part A, but detoxification-only programs at standalone facilities are not covered. If you need medical detoxification, you must go through a hospital emergency department or an inpatient rehabilitation facility.

How Medicare Advantage plans handle alcohol addiction treatment

If you have a Medicare Advantage plan (Part C), your coverage for addiction treatment may be different from Original Medicare. Some Advantage plans cover more outpatient visits or have lower copays for mental health services. Others may require prior approval before you start treatment, or they may limit which facilities you can use.

Contact your Medicare Advantage plan before you start any addiction treatment to find out what is covered, what your copays will be, and whether you need prior approval. Your plan's customer service number is on your insurance card. Ask specifically whether inpatient rehab at a particular facility is covered and whether your doctor's referral will be accepted.

Steps to take before starting treatment

First, talk to your primary care doctor or call your Medicare plan to confirm coverage. Your doctor can refer you to a Medicare-certified facility or a therapist who accepts Medicare. If you are looking for an inpatient program, ask the facility whether it is Medicare-certified and whether it accepts Medicare assignment (meaning it will bill Medicare directly and accept Medicare's approved amount as full payment).

Second, ask about your out-of-pocket costs. For inpatient stays, ask what the daily copay is and how many days the facility typically treats patients. For outpatient care, ask what your copay per visit will be and whether you have already met your Part B deductible for the year. If you have supplemental insurance (Medigap), check your policy to see whether it covers the copays Medicare does not pay.

Third, if cost is a barrier, ask your doctor or the treatment facility whether they offer financial information or sliding-scale fees. Some facilities have programs for uninsured or underinsured patients, and some community health centers offer low-cost addiction counseling regardless of insurance status.

When to seek emergency care for alcohol withdrawal

Alcohol withdrawal can be dangerous and requires when ready medical attention. Go to the emergency department or call 911 if you experience severe shaking, confusion, hallucinations, rapid heartbeat, or seizures after stopping or reducing alcohol use. The emergency department is covered under Medicare Part A, and doctors there can stabilize you and refer you to inpatient rehabilitation if needed.

If you are thinking about harming yourself, call the 988 Suicide and Crisis Lifeline (call or text 988) or go to the nearest emergency department. This service is free and available 24 hours a day.

Frequently Asked Questions

Does Medicare cover medication to stop drinking?

Yes, medications like naltrexone, acamprosate, and disulfiram are covered under Medicare Part D if your prescription drug plan includes them. You pay your plan's copay or coinsurance. Some medications require prior approval, so ask your doctor to check with your plan before the pharmacy fills the prescription.

Can I use Medicare to pay for a 30-day residential rehab program?

Only if the facility is a Medicare-certified rehabilitation facility or a hospital with an inpatient addiction treatment unit. Private residential centers that are not hospital-based are not covered. Ask the facility whether it is Medicare-certified before you enroll.

Do I need my doctor's permission to start outpatient counseling?

No, you can contact a therapist or counselor directly as long as they accept Medicare. However, telling your primary care doctor is a good idea so they know about your treatment and can coordinate care. Your doctor can also refer you to providers they trust.

What if I have both Medicare and Medicaid?

Medicaid rules vary by state, and some states cover addiction treatment services that Medicare does not. Contact your state Medicaid office or your Medicaid case manager to learn what is covered under your state's plan. In some cases, Medicaid may cover residential treatment that Medicare does not.

How do I find a Medicare-certified rehab facility near me?

Ask your doctor for a referral, or call your Medicare plan's customer service line and ask for a list of in-network rehabilitation facilities. You can also search the Medicare Care Compare tool at Medicare.gov by entering your zip code and selecting "rehabilitation facilities." Always confirm the facility accepts Medicare before you explore.
