Methadone Clinics by State
Every clinic listed below is a currently SAMHSA-certified opioid treatment program (OTP) according to the CMS Medicare Provider OTP file dated January 5, 2026. Methadone for opioid use disorder is only legally dispensed at federally certified OTPs, which means this list is bounded by federal law, not by directory coverage decisions.
