KING ET AL. v. BURWELL, SECRETARY OF HEALTH AND HUMAN SERVICES, ET AL.

"The Patient Protection and Affordable Care Act grew out of a long history of failed health insurance reform. In the 1990s, several States sought to expand access to coverage by imposing a pair of insurance market regulations—a “guaranteed issue” requirement, which bars insurers from denying coverage to any person because of his health, and a “community rating” requirement, which bars insurers from charging a person higher premiums for the same reason. The reforms achieved the goal of expanding access to coverage, but they also encouraged people to wait until they got sick to buy insurance. The result was an economic “death spiral”: premiums rose, the number of people buying insurance declined, and insurers left the market entirely. In 2006, however, Massachusetts discovered a way to make the guaranteed issue and community rating requirements work—by requiring individuals to buy insurance and by providing tax credits to certain individuals to make insurance more affordable. The combination of these three reforms—insurance market regulations, a coverage mandate, and tax credits—enabled Massachusetts to drastically reduce its uninsured rate.

The Affordable Care Act adopts a version of the three key reforms that made the Massachusetts system successful. First, the Act adopts the guaranteed issue and community rating requirements. 42 U. S. C. §§300gg, 300gg–1. Second, the Act generally requires individuals to maintain health insurance coverage or make a payment to the IRS, unless the cost of buying insurance would exceed eight percent of that individual’s income. 26 U. S. C. §5000A. And third, the Act seeks to make insurance more affordable by giving refundable tax credits to individuals with household incomes between 100 per cent and 400 percent of the federal poverty line..."
