Does Insurance Cover Rehab? A Plain-Language Guide to Paying for Addiction Treatment

Learn what insurance, Medicaid, and Medicare cover for addiction treatment, how to check your benefits and appeal a denial, and how to get help if you have no insurance.

Worrying about cost is one of the most common reasons people put off getting help for drug or alcohol use. The good news is that most health insurance now covers addiction treatment, and there are real options if you have no insurance at all.

This guide explains, in plain language, what insurance usually covers, how Medicaid and Medicare work for rehab, what to do if you are uninsured, and the questions to ask before you start a program. It is written for people seeking treatment for themselves and for family members trying to help someone they love.

If you or someone you love is in danger right now, call or text 988 to reach the 988 Suicide and Crisis Lifeline, or call 911. For free, confidential treatment referrals, including help finding low-cost programs, call the SAMHSA National Helpline at 1-800-662-4357, available 24/7 in English and Spanish (SAMHSA).

Does Insurance Cover Rehab?

In most cases, yes. Under the Affordable Care Act, all Marketplace plans must cover mental health and substance use disorder services as essential health benefits, including substance use disorder treatment, counseling, and inpatient behavioral health care (HealthCare.gov).

Marketplace plans also cannot:

• Deny you coverage or charge you more because of a pre-existing mental health or substance use condition
• Put yearly or lifetime dollar limits on mental health and substance use coverage

(HealthCare.gov)

"Covered" does not always mean free. You may still owe a deductible, copays, or coinsurance, and your plan may only pay in full for certain programs. The rest of this guide explains how to find out exactly what you will pay.

Parity: Addiction Treatment Should Be Covered Like Other Medical Care

A federal law called the Mental Health Parity and Addiction Equity Act generally means health plans cannot make mental health and substance use benefits harder to use than medical and surgical benefits (CMS).

In practice, that means limits on addiction treatment generally cannot be stricter than limits on other medical care when it comes to:

• Costs: deductibles, copays, coinsurance, and out-of-pocket maximums
• Treatment limits: caps on the number of days or visits
• Approval rules: requirements to get approval before treatment

(HealthCare.gov)

The law applies to employer group plans and individual plans, with some differences for small employer plans (CMS). If your plan seems to treat addiction care much more strictly than other care, ask your plan about it in writing.

What Insurance Usually Covers

Coverage depends on your plan and your state, but plans often cover care across the levels of treatment:

• Detox (medically managed withdrawal)
• Residential or inpatient treatment
• Partial hospitalization and intensive outpatient programs (IOP)
• Outpatient counseling and group therapy
• Medications for addiction, such as buprenorphine, naltrexone, and methadone
• Assessments to figure out the right level of care

Not sure what these levels mean? Our guide to treatment levels of care explains each one.

What insurance usually does not cover: rent at a sober living home. Sober living is housing, not treatment, though treatment you receive while living there may be covered. Learn more in our guide to sober living and recovery residences.

How to Use Private or Employer Insurance for Rehab

If you have insurance through work or on your own, these steps can save you money and stress:

1. Call the member services number on your insurance card. Say you are looking for substance use disorder treatment and ask what your plan covers.
2. Ask for in-network programs. In-network providers have agreed to your plan's rates. Out-of-network care can cost much more or may not be covered at all.
3. Ask about prior authorization. Many plans require approval before residential treatment or IOP. The program you choose can often request this for you.
4. Ask what you will owe. Find out your deductible, how much of it you have met, your copay or coinsurance for each level of care, and your out-of-pocket maximum.
5. Let the program check your benefits too. Most treatment programs will verify your insurance for free before you start. Ask them to explain your expected costs in writing.

What If My Insurance Denies Treatment?

You have the right to appeal. If your insurer refuses to pay for care, it must tell you why and how to dispute the decision (HealthCare.gov).

• Internal appeal: You ask your insurance company to fully review its decision. If your situation is urgent, the insurer must speed up the process.
• External review: If the denial stands, you can take it to an independent third party, so the insurance company no longer has the final say.

(HealthCare.gov)

Ask the treatment program for help. Many programs have staff who handle appeals and can provide records showing why the care is medically necessary.

Does Medicaid Cover Rehab?

Yes. Medicaid is the single largest payer for mental health services in the United States and plays a growing role in paying for substance use disorder treatment (Medicaid.gov). Medicaid is run by each state, so covered services and eligibility rules vary.

A few things to know:

• You can apply any time of year. You do not have to wait for an enrollment period (HealthCare.gov).
• You can apply two ways: through HealthCare.gov or your state's marketplace, or directly through your state Medicaid agency (HealthCare.gov).
• Not every program accepts Medicaid. Always ask a program whether it accepts your state's Medicaid or your Medicaid managed care plan before you start.
• Children and teens in families that earn too much for Medicaid may qualify for CHIP. See our paying for care guide for more.

Does Medicare Cover Rehab?

Medicare covers many substance use disorder services (Medicare.gov):

• Part A covers inpatient care in a general or psychiatric hospital.
• Part B covers outpatient treatment, intensive outpatient programs, partial hospitalization when certain requirements are met, and services from doctors and other providers.
• Part D covers many prescription medications.

For opioid use disorder, Part B covers methadone, buprenorphine, counseling, and therapy through Medicare-enrolled Opioid Treatment Programs. At these programs there are no copays, though the Part B deductible applies. People with both Medicare and Medicaid pay nothing for services covered through their state Medicaid program (Medicare.gov).

Help for Veterans and Military Families

The VA offers a full range of substance use treatment, including detox, medications like methadone and buprenorphine, outpatient and intensive outpatient care, residential care, family counseling, and continuing care (VA). To get started, apply for VA health care, talk with your VA primary care provider, or call 800-827-1000 (VA).

Military members, retirees, and their families with TRICARE can also get substance use treatment. Use the VA / TRICARE filter on Waypoint to find community programs that accept these benefits.

How to Pay for Rehab Without Insurance

Not having insurance does not mean you cannot get treatment. Here are the main options:

• State-funded treatment. Every state has an office that runs state-funded treatment programs. If you have no insurance or not enough coverage, the SAMHSA National Helpline will refer you to that office (SAMHSA).
• Sliding-scale fees. Many programs charge based on your income. SAMHSA's helpline can often refer you to programs that use a sliding fee scale or accept Medicare or Medicaid (SAMHSA).
• Apply for Medicaid. If your income is low, you may qualify, and you can apply any time (HealthCare.gov).
• Look into a Marketplace plan. Because addiction treatment is an essential health benefit, a Marketplace plan must cover it, and pre-existing conditions cannot be used against you (HealthCare.gov).
• Community and nonprofit programs. Some community clinics, peer recovery centers, and faith-based programs offer free or low-cost services.
• Payment plans. Some private programs let you pay over time. Get the terms in writing.

Questions to Ask a Program About Cost

Before you commit to a program, ask:

1. Do you accept my insurance, Medicaid, or Medicare? Are you in-network?
2. Will you verify my benefits and tell me my expected costs in writing?
3. Do you need prior authorization, and will you request it for me?
4. What is the total cost, and what does it include, such as medications, testing, and room and board?
5. Do you offer a sliding scale, payment plan, or financial assistance?
6. What happens if my insurance stops paying before treatment is finished?
7. Will I get separate bills from doctors, labs, or other providers?

Watch Out for "Free Rehab" Offers That Sound Too Good

Be cautious if someone offers free travel, free rent, or cash to go to a specific treatment program, or asks for your insurance information before talking about your needs. Paying someone to steer patients to a program is called patient brokering, and it is illegal in many places (SAMHSA). Choose a program based on the care it provides, not on perks.

Common Questions About Paying for Rehab

How much does rehab cost?

It varies widely depending on the level of care, how long you stay, where you live, and your insurance. Outpatient care usually costs far less than residential treatment. The best way to know your cost is to ask the program to check your benefits and give you an estimate in writing.

Can I go to rehab if I have a high deductible?

Yes. You may pay more up front until you meet your deductible. Ask the program about payment plans, and ask your plan about your out-of-pocket maximum, which caps what you pay in a year.

Will my employer find out if I use my insurance for rehab?

Health information is generally private, and your insurer does not usually share the details of your treatment with your employer. If you need time off, ask your HR department about medical leave options without sharing more than you are comfortable with.

Can I get help paying for a family member's treatment?

Yes. Family members can call the SAMHSA National Helpline for referrals, and if your loved one is on your insurance plan, you can call the plan to ask about their benefits with their permission.
