Behavioral health issue brief: Medicaid managed care and behavioral health: an overview of 1915(b) and statewide 1115 waivers.

Section 1115 and Section 1915(b) of the Social Security Act permit federal waivers for States mandating mental health benefits to Medicaid recipients in managed care plans. Prevalent "carve-in" or "carve-out" provisions of these plans vary by type of coverage (e.g. substance abuse), geographic scope and eligible population targeted, including AFDC and low-income families.
