Medicaid reimbursement rates for primary care services and behavioral health outcomes.
This AHRQ-authored research studied the effects of changing Medicaid reimbursement rates for primary care services on behavioral health outcomes-defined here as mental illness and substance use disorders. The authors applied two-way fixed-effects regressions to survey data specifically designed to measure behavioral health outcomes over the period 2010-2016. They found that higher primary care reimbursement rates reduce mental illness and substance use disorders among non-elderly adult Medicaid enrollees, although they interpreted findings for substance use disorders with some caution as they may be vulnerable to differential pre-trends. Overall, their findings suggest positive spillovers from a policy designed to target primary care services to behavioral health outcomes.

The role of primary care in the initiation of opioid use disorder treatment in statewide public and private insurance.
This observational study’s goal was to determine if individuals newly diagnosed with opioid use disorder (OUD) who saw a primary care provider (PCP) before or on the date of diagnosis had higher rates of medication treatment for OUD (MOUD). Claims data from Medicaid and a large private insurer in North Carolina from January 2014 to July 2017 was used. During the period from 2014 to 2017, the prevalence of diagnosed OUD increased by 47% among Medicaid enrollees and by 76% among the privately insured. Over the same time period the number of people with an OUD who received MOUD fell among both groups, while PCP involvement in treatment increased. The percent of Medicaid enrollees receiving buprenorphine from a PCP increased from 32% in 2014 to 39% in 2017. In the 12 months before being newly diagnosed, approximately 82% with Medicaid or private insurance had a PCP visit. There was no difference in receiving an MOUD with those who had not seen a PCP. However, there was a higher probability of receiving MOUD with a PCP, than seeing an emergency provider, but lower than seeing a behavioral health specialist or other provider type.
