Paying for Rehab
Rehab That Takes Medicaid
How Do I Find Rehab That Takes Medicaid?
Rehab that takes Medicaid is easy to find: SAMHSA lists 9,569 of its 11,833 substance use treatment facilities as accepting Medicaid (October 2026). Every state Medicaid program covers some addiction treatment, and federal rules require coverage of medication for opioid use disorder. Search the treatment finder with the Medicaid filter, then call to confirm the program takes your state's plan.
Rehab That Takes Medicaid Is the Most Common Kind
If you have Medicaid, most addiction treatment programs will take it. SAMHSA’s directory lists 9,569 facilities that accept Medicaid out of 11,833 substance use treatment facilities nationwide (October 2026). That’s more than accept private insurance (9,562) and far more than accept Medicare (6,596).
Medicaid is a joint federal and state program. HealthCare.gov describes it as free or low-cost health coverage for eligible low-income adults, families and children, pregnant women, older adults and people with disabilities. Each state runs its own program under federal rules, so what’s covered, who qualifies and what you pay can differ from state to state.
To find a program now, open the treatment finder, enter your ZIP code and turn on the Medicaid filter. If you aren’t sure whether you’re covered yet, the Can I Pay for Treatment? checker walks through your options by state.
What Medicaid Covers for Addiction Treatment
Every state covers some substance use treatment, but the list of services is set state by state. Here’s what applies across the country:
- Medication for opioid use disorder. CMS made coverage of medication for opioid use disorder a mandatory part of state Medicaid plans, and in November 2024 it issued guidance on making that requirement permanent. This includes the medicines described in medication for opioid use disorder, given at methadone clinics and doctors’ offices.
- Expansion adults get the essential health benefits. Adults who qualify through Medicaid expansion get an Alternative Benefit Plan, and Medicaid.gov says those plans must cover all 10 essential health benefits. One of them is substance use disorder treatment, along with counseling and inpatient behavioral health services.
- Parity rules apply. A 2016 federal rule applied the Mental Health Parity and Addiction Equity Act to Medicaid managed care plans and expansion plans. In short, limits on addiction care can’t be stricter than limits on medical care. Does insurance cover rehab? explains parity in more detail.
Beyond that, states choose. Many cover the full range of care, from outpatient counseling to residential treatment. Some typical lists from state Medicaid offices:
| State program | Substance use services the state lists |
|---|---|
| Health First Colorado | Screening, early intervention, outpatient, intensive outpatient, partial hospitalization, medication treatment, withdrawal management, residential and hospital inpatient care |
| Texas Medicaid | Assessment, individual and group counseling, residential treatment, withdrawal management, methadone and buprenorphine treatment |
| Florida Medicaid | Assessments, medical and psychiatric services, individual, group and family therapy, rehabilitative services |
| Medi-Cal (California) | Intensive outpatient, residential treatment, voluntary inpatient detox, outpatient drug-free services, narcotic treatment services |
The level of care you get starts with an assessment. FindTreatment.gov says everyone entering treatment gets a clinical assessment to match them with the right type of care. The levels of care tool shows how detox, residential, intensive outpatient and outpatient care differ.
Medicaid Expansion States vs. States That Haven’t Expanded
Whether you can get Medicaid often depends on where you live. In states that expanded Medicaid under the Affordable Care Act, HealthCare.gov says you can qualify on income alone if your household earns below 138% of the federal poverty level.
In states that haven’t expanded, many adults can’t qualify on income alone. HealthCare.gov says adults below 100% of the poverty level who don’t qualify by disability, age or another factor fall into a coverage gap. Their income is too high for their state’s Medicaid and too low for Marketplace savings.
Forty states and D.C. have expanded Medicaid. Ten haven’t. The table also shows which states have an SUD Section 1115 demonstration, explained in the next section.
| Group | States |
|---|---|
| Expanded Medicaid and has an SUD 1115 demonstration | Alaska, California, Colorado, Connecticut, Delaware, District of Columbia, Illinois, Indiana, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, Utah, Vermont, Virginia, Washington, West Virginia |
| Expanded Medicaid | Arizona, Arkansas, Hawaii, Idaho, Iowa, North Dakota, South Dakota |
| Hasn’t expanded, has an SUD 1115 demonstration | Kansas (KanCare), Wisconsin (BadgerCare Reform) |
| Hasn’t expanded | Alabama, Florida, Georgia, Mississippi, South Carolina, Tennessee, Texas, Wyoming |
If you live in a state that hasn’t expanded, apply anyway. HealthCare.gov says every state covers some groups based on income, household size, pregnancy, caring for young children, disability and age. If you don’t qualify, free and low-cost rehab covers state-funded treatment for people without insurance.
What a Section 1115 SUD Waiver Changes
A Section 1115 demonstration, often called a waiver, lets a state test changes to its Medicaid program with federal approval. Medicaid.gov says the SUD demonstrations give states flexibility to improve the continuum of care for people with substance use disorders, including opioid use disorder. The table above shows the states medicaid.gov lists with an approved SUD demonstration as of October 2026.
In practice, each state uses its demonstration differently. Nevada’s, for example, covers treatment in an institution for mental diseases for up to 30 days. Montana’s adds contingency management and re-entry services for people leaving incarceration.
You don’t apply for a waiver yourself. If your state has one, the extra services come with your Medicaid coverage. Your state page lists what your state covers: Colorado, Florida, Texas and California, or any state from the finder.
Where to Find It: Accepts Medicaid by State
SAMHSA's FindTreatment.gov lists 9,569 substance use treatment facilities with this service (accepts medicaid) across 53 states and territories, checked October 2026. Pick a state for its facilities, cities and treatment agency.
How to Apply for Medicaid
You can apply at any time of year. There’s no open enrollment period for Medicaid.
- Apply through the Marketplace at HealthCare.gov or your state’s marketplace. If anyone in your household looks eligible, your information goes to your state Medicaid agency, which contacts you about enrollment.
- Or apply directly with your state Medicaid agency. HealthCare.gov lists each state agency’s contact information.
- Check the immigration rules. Under a recent law change, only people with certain immigration statuses, such as lawful permanent residents, can get full Medicaid.
- Ask about past bills. Medicaid may help pay for care from the last 3 months, even if you weren’t enrolled yet.
You don’t have to wait for approval to start looking for a program. If you’re waiting on a decision, the state-funded options on free and low-cost rehab may help in the meantime.
How to Find a Program That Takes Your Plan
Many states deliver Medicaid through private insurance companies, often called managed care plans. A program can accept Medicaid in general but not contract with your specific plan, so check both.
- Search the finder. Use the treatment finder with the Medicaid filter and your ZIP code. In Florida, 271 of 484 listed facilities accept Medicaid; in Colorado, 203 of 248 do (October 2026).
- Call your plan. The member services or behavioral health number on your Medicaid card can give you a list of in-network programs and tell you if you need a referral or prior approval.
- Call the program. Ask whether it takes your plan by name, when you can start and whether there’s a waitlist. FindTreatment.gov advises trying another program if one can’t see you within 48 hours.
- Get help if you’re stuck. SAMHSA’s National Helpline, 1-800-662-4357, is free, confidential and open 24/7 in English and Spanish, and can often refer you to facilities that accept Medicaid. You can also text your ZIP code to 435748.
Be wary of anyone who offers free travel to an out-of-state program in exchange for your Medicaid information. How to choose a rehab you can trust covers the warning signs.
Medi-Cal Rehab in California
In California, Medicaid is called Medi-Cal, and addiction treatment runs through Drug Medi-Cal and the Drug Medi-Cal Organized Delivery System, part of the state’s CalAIM demonstration. To get these services, you start with your county.
Medi-Cal covers intensive outpatient treatment, residential treatment, voluntary inpatient detox, outpatient drug-free services and narcotic treatment services such as methadone. The easiest way in is your county’s 24/7 access line, listed by the California Department of Health Care Services. In Los Angeles County, for example, call (800) 854-7771 and choose option 2.
SAMHSA lists 477 facilities in California that accept Medicaid, out of 902 in the state (October 2026). For Medi-Cal detox or inpatient care, search the finder with the Medicaid filter plus detox or residential care, or see the California page for state contacts. For a step down from residential care, intensive outpatient programs are covered too.
Costs to Ask About Before You Start
A sober living home isn’t treatment, so don’t assume Medicaid will pay the rent. Some state demonstrations add housing help: Nevada’s covers housing and nutrition supports for eligible members, and Montana’s covers tenancy support services. Ask your plan what applies to you.
A program that doesn’t take Medicaid, or isn’t in your plan’s network, may bill you directly. Before you agree to anything, ask the program and your plan what you’ll owe. How much does rehab cost? explains what drives the price.
Frequently Asked Questions
Does Medicaid Cover Inpatient Rehab?
Often, yes, but the details depend on your state. Colorado, Texas and California, for example, list residential treatment among their covered services, and states with an SUD Section 1115 demonstration have federal flexibility to broaden the care they pay for. Your state's Medicaid office or health plan can tell you what your plan pays for. See inpatient and residential rehab.
Does Medicaid Cover Rehab for Alcohol?
Yes. Medicaid covers treatment for alcohol use disorder the same way it covers treatment for other substance use disorders: counseling, outpatient care and, in most states, more intensive levels of care. See alcohol rehab for how treatment works.
Will Medicaid Pay for Detox?
Many state programs do. California, Colorado, Ohio, Oklahoma and Virginia, for example, list detox or withdrawal management among their covered substance use services. Alcohol and benzodiazepine withdrawal can be dangerous, so ask for medically supervised detox. See detox.
Can I Get Medicaid if My State Didn't Expand It?
Possibly. HealthCare.gov says every state covers some low-income groups, including families with children, pregnant women and people with disabilities, and urges you to apply even if you think you won't qualify.
Can Medicaid Pay for Treatment I Got Before I Enrolled?
Sometimes. HealthCare.gov says Medicaid may help pay for medical care from the last 3 months, even if you weren't enrolled at the time, depending on your family's income and medical expenses then.
Can a Program Turn Me Away if It Takes Medicaid?
A program can be full, or may not contract with your managed care plan. If a program can't see you within 48 hours, FindTreatment.gov suggests trying another one. The SAMHSA National Helpline, 1-800-662-4357, can refer you to programs that accept Medicaid.
