Medicaid Coverage for Rehab

Last reviewed 2026-08-01

Medicaid is required to cover substance use disorder treatment in every state, making it one of the largest funders of addiction treatment in the country.

What varies by state

Specifics differ: which levels of care are covered, which providers accept Medicaid, and whether a program requires prior authorization. Some states have expanded Medicaid coverage further through 1115 waivers specifically for substance use treatment.

Finding a Medicaid provider

Not every treatment center accepts Medicaid, so it's worth confirming directly before enrolling. Your state's Medicaid office or the SAMHSA National Helpline (1-800-662-4357) can help identify in-network options.
