Certified Community Behavioral Health Clinic Demonstration Impact on Health Care Utilization Among Non-Medicaid Patients with Severe Mental Illnesses

In 2017, the Certified Community Behavioral Health Clinic (CCBHC) demonstration was implemented in New York State to redesign care delivery and financing for behavioral health services. Although CCBHC primarily targeted Medicaid patients, it was hypothesized that the clinic-level benefits of CCBHC were expected to impact even non-Medicaid patients treated in CCBHCs. To test this hypothesis, this study conducted a health insurance claims data analysis of non-Medicaid (ie, commercial and Medicare) patients with severe mental illnesses, comparing a cohort of CCBHC-treated patients with a propensity score-matched comparison cohort of patients treated by non-CCBHC clinics on rates of mental health service utilization, hospitalization, and emergency department (ED) visits. The data suggested CCBHC was associated with more than 10% increase in outpatient mental health service utilization by the patients' second year of CCBHC exposure, accompanied by similarly significant reductions in the rates of all-cause ED visits and non-psychiatric hospitalization. These findings suggest that for behavioral health clinics that serve a sufficiently large population of Medicaid, the impact of innovative clinical redesign attributable to CCBHC is likely to extend to all patients treated by them.
