The Implications of the Affordable Care Act for Behavioral Health Services Utilization.

This analysis estimates the number of currently uninsured adults who may gain coverage and access behavioral health (BH) services under the ACA. Data on BH status, socio-demographic characteristics, insurance coverage, and services utilization were drawn from the 2008-2012 National Survey on Drug Use and Health. Multivariate logistic regression modeling was used to estimate changes in services utilization under the ACA. Estimates indicate that 2.8 million adults may receive BH treatment through Medicaid expansions, and 3.1 million through participation in health insurance exchanges. This represents a 40% increase in BH services utilization, primarily for mental health services.
