Insurance barriers to substance use disorder treatment after passage of mental health and addiction parity laws and the affordable care act: A qualitative analysis.

Introduction: People who use drugs (PWUDs) in the United States historically have had a higher probability of being uninsured. Passage of the Affordable Care Act, the Paul Wellstone and Pete Domenici Health Parity and Addiction Equity was expected to increase access to treatment for substance use disorder. Few studies to date have conducted qualitative research with substance use disorder (SUD) treatment providers regarding Medicaid and other insurance coverage of SUD treatment following passage of the ACA and parity laws. The present paper fills this gap by reporting data from in-depth interviews with treatment providers from three states, Connecticut, Kentucky, and Wisconsin, that differ in implementation of the ACA. Methods: Study teams in each state conducted in-depth, semi-structured interviews with key informants who provided SUD treatment, including providers of behavioral health residential or outpatient programs, office-based buprenorphine providers and opioid treatment programs [OTP, i.e. methadone clinics] ( Results: Results from this study suggest that the promise of the ACA and parity laws to increase access to SUD treatment has only partially been realized. There is wide variation among the three states' Medicaid programs and among private insurance in the types of SUD treatment that is covered. Neither Kentucky's nor Connecticut's Medicaid covered methadone. Wisconsin Medicaid did not cover residential or intensive outpatient treatment. Thus, none of the states studied here provided all levels of care that the ASAM recommends for treating SUD. Further, there were several quantitative limits placed on SUD treatment such as number of urine drug screens or visits allowed. Providers complained that many treatments required prior authorizations, including MOUD like buprenorphine. Conclusions: More reform is needed to make SUD treatment accessible to all who need it. Such reforms should consider defining standards for opioid use disorder treatment with reference to evidence-based practices, not be attempting parity with an arbitrarily defined medical standard.
