Medicaid Waivers and Access to Behavioral Health Services: What Is Known and What Can Be Expected

In the past 5 years, Medicaid programs have implemented administrative barriers to enrollment. The impact of these provisions on access to mental health and substance use disorder treatment has been largely unstudied. This column reviews the literature on the previous changes to Medicaid enrollment and treatment use, current policy landscape, and steps that states or localities may take to offset these administrative burdens. Redirecting savings to other safety-net programs may increase access to care, but these programs lack the comprehensive benefits provided by Medicaid. Without another backstop, the implementation of these barriers will likely exacerbate the United States’ behavioral health crises.
