The Affordable Care Act and the Faltering Revolution in Behavioral Health Care.

Often described in such terms as a "revolution" and a "game-changer" for the behavioral health sector in the United States, the Affordable Care Act has helped to enhance coverage for mental health and substance use disorders while encouraging service system innovations at the organizational level.
