This report is intended to support state Medicaid agencies and payers in improving access to substance use disorder treatment, with a special focus on medication-assisted treatment (MAT) for opioid use disorder. With support from Arnold Ventures, TAC and partners conducted a review of state activities that have significantly increased both the number of individuals receiving MAT for opioid use disorder, and the number of providers delivering MAT services.
