The short answer
Yes, Medicaid generally covers addiction treatment, and it is one of the largest payers of this care in the U.S. Which services it covers and how you get them vary by state. Federal changes beginning in 2027 may affect some enrollees, but people in qualifying treatment are expected to be exempt from the new work requirements.
What Medicaid usually covers
Depending on your state, Medicaid may cover:
- Screening and assessment
- Outpatient counseling and group therapy
- Intensive outpatient and partial hospitalization programs
- Detox and withdrawal management
- Residential treatment, in many states
- Medication for opioid, alcohol and tobacco use disorders
- Care for co-occurring mental health conditions
(For what each level involves, see [Inpatient vs Outpatient Rehab: Which Level of Care Is Right for You?] and [Medication-Assisted Treatment (MAT): How It Works and Who It’s For].)
Why coverage varies by state
Each state runs its own Medicaid program within federal rules, so benefits, providers and rules differ. For example:
- Residential care: federal rules have historically limited Medicaid payment for stays in larger residential treatment facilities, though many states have waivers that allow coverage. Ask your state.
- Managed care plans: many states use private plans to deliver Medicaid, each with its own network of providers.
- Prior authorization and limits on days can differ.
Who qualifies
Eligibility depends on your income, household size, age, disability status and state. Many adults qualify in states that expanded Medicaid. In states that did not expand, adults without children often have fewer options. To check, contact your state Medicaid agency or apply through HealthCare.gov or your state’s marketplace.
What is changing in 2027
A federal law signed in July 2025 changes Medicaid for some adults. Key points:
- Starting January 1, 2027, adults ages 19 to 64 in Medicaid expansion programs must complete 80 hours a month of qualifying activities, with exemptions for groups including people with serious mental health or substance use disorders. ensorahealth
- People diagnosed with a substance use disorder or actively in treatment are exempt, but the details are still being worked out. One provider executive noted that the exemption applies to participation in a “qualifying” treatment program, not to every substance use disorder. bhbusinessbhbusiness
- States can choose to start work requirements earlier than 2027. propel
- Starting in 2027, retroactive coverage is limited to one month for adults in the expansion group. astho
- New cost-sharing rules for expansion adults are scheduled to begin in October 2028, and they exempt substance use treatment. propel
What to do: watch for letters or emails from your state Medicaid agency, keep documentation of your treatment, and ask your program how it can help you document your exemption. Rules are still being finalized, so confirm details with your state.
How to use Medicaid for treatment
- Confirm you are enrolled and find your plan’s name and member ID.
- Call the number on your card and ask which addiction treatment services are covered and which providers are in your network.
- Search FindTreatment.gov for providers and check which accept Medicaid. Then confirm directly with the program.
- Ask about prior authorization and any limits on days or visits.
- Ask about medication for opioid, alcohol or tobacco use disorders.
- Get help if you are denied. You have the right to appeal, and your program or state agency can often help.
