What Happens When Employers Switch from a "Carve-Out" to a "Carve-In" Model of Managed Behavioral Health?

This study examines how specialty BH care patterns change when employees and dependents are moved from a "carve-out" plan to a "carve-in" plan. METHODS: Linked insurance claims, eligibility, plan and employer data from 2008-14 were obtained for three Optum( employers who dropped their carve-out contracts but retained their carve-in plans. A longitudinal "difference-in-differences" study design was used to compare changes in BH services use over time among individuals who were: (i) moved to carve-in plans when the employer dropped its carve-out contract (N=177,653); and (ii) enrolled in carve-in plans before and after the transition (N=58,658). Outcomes included total and inpatient expenditures, broken down by plan, patient, and total; outpatient visits for assessment, individual psychotherapy, family psychotherapy, and medication management; and days of structured outpatient care, day treatment, residential care, and acute inpatient care. We pooled person-year observations and estimated regressions including individual fixed effects, year dummies and interactions between indicators for post-transition period and whether transitioned from carve-out to carve-in. RESULTS: Relative to individuals continuously in carve-in plans, those who were transitioned experienced significant increases in inpatient utilization (beta =.02; p=.05) and patient inpatient costs (beta =2.35; p=.01) and decreases in day treatment (beta =-0.01; p=.02). Our conclusions proved robust aga...
