Medicaid Expansion Dramatically Increased Coverage for People with Opioid-Use Disorders, Latest Data Show

Center on Budget and Policy PrioritiesThis report from the Center on Budget and Policy Priorities examines the latest data from the federal Agency for Healthcare Research and Quality. The study highlights the importance of the Affordable Care Act’s Medicaid expansion in increasing insurance coverage among people with opioid use disorders (OUDs) and offers a comprehensive picture of opioid-related hospitalizations around the country. The study finds that the share of hospitalizations in which a patient was uninsured fell dramatically in states that expanded Medicaid: from 13.4 percent in 2013 (the year before expansion took effect) to just 2.9 percent two years later. This steep decline indicates that many uninsured people coping with OUDs have gained coverage through Medicaid expansion.
