Carve-out plan financial requirements associated with national behavioral health parity.

OBJECTIVES:To examine changes in carve-out financial requirements (copayments, coinsurance, use of deductibles, and out-of-pocket maxima) following the Mental Health Parity and Addiction Equity Act (MHPAEA). DATA SOURCE/STUDY SETTING:Specialty mental health benefit design information for employer-sponsored carve-out plans from a national managed behavioral health organization's claims processing engine (2008-2013). STUDY DESIGN:This pre-post study reports linear and logistic regression as the main analysis. DATA COLLECTION/EXTRACTION METHODS:NA. PRINCIPAL FINDINGS:Copayments for in-network emergency room (-$44.9, 95% CI: -78.3, -11.5; preparity mean: $56.2), outpatient services (eg, individual psychotherapy: -$7.4, 95% CI: -10.5, -4.2; preparity mean: $17.8), and out-of-network coinsurance for emergency room (-11 percentage points, 95% CI: -16.7, -5.4; preparity mean: 38.8 percent) and outpatient (eg, individual psychotherapy: -5.8 percentage points, 95% CI: -10.0, -1.6; preparity mean 41.0 percent) decreased. Probability of family OOP maxima use (29 percentage points, 95% CI: 19.3, 38.6; preparity mean: 36 percent) increased. In-network outpatient coinsurance increased (eg, individual psychotherapy: 4.5 percentage points, 95% CI: 1.1, 7.9; preparity mean: 2.7 percent), as did probability of use of family deductibles (15 percentage points, 95% CI: 6.1, 23.3; preparity mean: 38 percent). CONCLUSIONS:MHPAEA was associated with increased generosity in most financial requirements observed here. However, increased use of deductibles may have reduced generosity for some patients.
