What Does Medicaid Cover for Addiction Treatment?

Medicaid provides coverage for substance use disorder treatment as part of its behavioral health benefits. Under federal law — specifically the Mental Health Parity and Addiction Equity Act (MHPAEA) and the Affordable Care Act — Medicaid is required to cover addiction treatment at the same level as other medical conditions.

This means your Medicaid plan covers multiple levels of care, from initial detox through long-term outpatient support. The specific costs, referral requirements, and network restrictions depend on your plan type — see the plan comparison below.
