What Medicaid has to cover for opioid treatment
If you have Medicaid, or could get it, the rules are in your favor.
Federal law requires every state Medicaid program to cover medications for opioid use disorder. That means all three approved medications: methadone, buprenorphine and naltrexone, in each of their approved forms. Congress made this requirement permanent in 2024.
The same rule covers the counseling and behavioral therapy that go along with the medication.
Beyond that, states choose. Many also cover withdrawal management, intensive outpatient programs and residential treatment, but the list is different in every state. Your plan’s member handbook spells out what yours includes.
Most people on Medicaid are in a managed care plan run by an insurance company. If that is you, the plan name is on your card, and that plan decides which clinics are in network.
What you might pay with Medicaid
For most people, very little. States are allowed to charge copays, but for people with low incomes those are limited to small amounts set by federal rules.
Some groups are exempt from most out-of-pocket costs. Pregnancy-related services, for example, cannot carry a copay.
If a clinic asks you for cash for care you thought was covered, call your plan before you pay.
Who qualifies in expansion and non-expansion states
| Expansion states | Non-expansion states | |
|---|---|---|
| Adults without children | Usually qualify if household income is at or below 138% of the federal poverty level. | Usually do not qualify on income alone. |
| Parents | Qualify under the same income limit. | May qualify, but income limits are often much lower. |
| Pregnancy | Covered, often at higher income limits. | Covered, often at higher income limits. |
| Disability | Covered through separate rules. | Covered through separate rules. |
Most states have expanded Medicaid. In those states, income is the main test for adults. The limit is officially 133% of the federal poverty level, and the way it is calculated makes it work out to 138%.
In states that have not expanded, some adults earn too much for Medicaid and too little for help with a marketplace plan. HealthCare.gov calls this falling into a gap. If that is you, the options on our page about treatment with no insurance still apply.
In every state, you generally need to live in the state and be a U.S. citizen or a qualified non-citizen. Rules change, so the only sure way to know is to apply.
How to apply for Medicaid
You can apply any time of year. There is no enrollment window to wait for.
- Apply through the marketplace. Fill out an application at HealthCare.gov. If it looks like you qualify, your information is sent to your state agency.
- Or apply with your state. Every state Medicaid agency takes applications directly, online, by phone or in person.
Have your household size and income ready. Your state will contact you about enrollment.
Some clinics and hospitals have staff who help people apply. When you call a clinic, ask if they have someone who does Medicaid enrollment.
You do not have to wait for an approval letter to start asking questions. Clinics can tell you how they handle patients whose application is still pending.
What to ask a clinic that takes Medicaid
Taking Medicaid is not one yes or no answer. Clinics contract with specific plans, and some limit how many Medicaid patients they see. Ask:
- Do you take my specific plan? Read them the plan name from your card.
- Are you accepting new Medicaid patients right now, and how soon is the first appointment?
- Which medications do you offer here?
- Does anything need approval from my plan before I start?
- Will I owe anything at the visit or at the pharmacy?
- If my coverage lapses, what happens to my treatment?

Questions people ask us
Does Medicaid cover methadone and Suboxone?
Yes. Federal law requires every state Medicaid program to cover the medications approved for opioid use disorder, including methadone and buprenorphine products, along with related counseling. Your plan may have rules about which pharmacy or clinic you use, so confirm with the member number on your card.
Does Medicaid pay for inpatient rehab?
It depends on your state. Medication treatment and counseling are required everywhere. Residential treatment is a state choice, and many states do cover it with limits. Call your plan and ask what it covers for residential rehab and whether approval is needed first.
Can I get Medicaid if I have a job?
Often, yes. Medicaid looks at household income and size, not whether you work. In states that expanded Medicaid, adults with income at or below 138% of the federal poverty level usually qualify. The fastest way to find out is to apply through HealthCare.gov or your state agency.
How long does it take to get approved?
It varies by state and by how complete your application is, so there is no single answer we can promise. Ask the clinic if it has enrollment staff who can help you apply, and ask how it handles patients whose application is still being reviewed.
