This report to the Medicaid and CHIP Payment and Access Commission (MACPAC) was prepared to support MACPACs March 2012 Report to the Congress on Medicaid and CHIP. The report presents national findings on access to care for children with Medicaid or CHIP using measures from two national household surveysthe National Health Interview Survey (NHIS) and the Household Component of the Medical Expenditure Panel Survey (MEPS). These estimates give a national picture of how access to care for children enrolled in Medicaid/CHIP compares to that of children with ESI and uninsured children, building on prior reports and analyses.
