Abstract

Objectives: Provisions in the Affordable Care Act (ACA) are likely to expand access to substance use disorder treatment for low-income individuals. The aim of the study was to provide information on the need for substance use disorder treatment among individuals who may be eligible for Medicaid under the ACA. Methods: The 2008 and 2009 National Survey on Drug Use and Health provided data on demographic characteristics, health status, and substance use disorders for comparison of current low-income Medicaid enrollees (N=3,809) with currently uninsured individuals with household incomes that may qualify them for Medicaid coverage beginning in 2014 (N=5,049). The incomes of the groups compared were 138%of the federal poverty level (133%provided in the ACA plus a 5%income "disregard" allowed by the law). Results: The rate of substance use disorders among currently uninsured incomeeligible individuals was slightly higher than the rate among current Medicaid enrollees (14.6%versus 11.5%, p=.03). Although both groups had significant unmet need for substance use disorder treatment, the treatment rate among those who needed treatment was significantly lower in the income-eligible group than in the currently enrolled group (31.3%versus 46.8%, p<.01). When the analysis excluded informal care received outside the medical sector, treatment rates among those with treatment needs were much lower in both groups (12.8%in the incomeeligible group and 30.7%among current enrollees). Conclusions: Findings suggest that Medicaid insurance expansions under the ACA will reduce unmet need for substance use disorder treatment.
