On October 3, 2018, the Senate overwhelmingly passed comprehensive, bipartisan legislation to address the opioid epidemic, sending the measure to President Trump who has indicated he will sign it. The bill, the Substance Use Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities (SUPPORT) Act, was passed earlier by the House and tackles many aspects of the epidemic, including treatment, prevention, recovery, and enforcement. While very broad in scope, the final legislation contains a number of provisions related to Medicaid’s role in helping states provide coverage and services to people who need substance use disorder (SUD) treatment, particularly those needing opioid use disorder (OUD) treatment.
