The Children’s Health Insurance Program Reauthorization Act of 2009 (CHIPRA) required GAO to study children’s access to dental care. GAO assessed (1) the extent to which dentists participate in Medicaid and the Children’s Health Insurance Program (CHIP) and federal efforts to help families find participating dentists; (2) data on access for Medicaid and CHIP children in different states and in managed care; (3) federal efforts to improve access in underserved areas; and (4) how states and other countries have used mid-level dental providers to improve children’s access.
