The Massachusetts health care reform law was enacted in 2006. It requires nearly every resident of Massachusetts to obtain health insurance coverage. Through the law, Massachusetts provides free health care for residents earning less than 150% of the federal poverty level, and partially-subsidized health care for those earning up to 300% of the FPL, depending on an income-based sliding scale. The law is credited with covering an additional 439,000 Massachusetts residents as of April 1, 2008.
