Opioid Treatment Program

Our holistic, person-centered quality framework of standards reflects leadership in the field internationally through the promotion and advancement of medication-assisted treatment (MAT) for persons diagnosed with opioid use disorder.

Opioid Treatment Programs (OTPs) provide medication-assisted treatment for persons diagnosed with opioid use disorder using any of three FDA-approved medications (methadone, buprenorphine, and naltrexone).

OTPs dispense medication and are certified by the Substance Abuse and Mental Health Services Administration (SAMHSA) Center for Substance Abuse Treatment (CSAT). To be certified by SAMHSA, an OTP must be accredited by a CSAT-approved accreditor such as CARF. We accredit the majority of OTPs in the United States.
