Unless Congress acts, federal funding for the Children’s Health Insurance Program (CHIP) will run out soon after September 2015. On March 26, the U.S. House of Representatives passed legislation that would fund CHIP for two more years. The Senate is expected to take up the bill in mid-April. This report, written by Robert Seifert of the Center for Health Law and Economics at the University of Massachusetts Medical School, examines the serious implications for Massachusetts if federal funding for CHIP is not extended.
