the supreme court is expected to issue a decision in a major new lawsuit against obamacare this june, and the health coverage for millions hangs in the balance.









this challenge to the affordable care act, called king v. burwell, came from longtime obamacare opponents who claim that, because of a key phrase in the law, the federal government may provide tax credit subsidies only in states that operate their own health insurance exchanges. thirty-four states declined to establish these marketplaces, and instead left that responsibility in the hands of the federal government.









if the supreme court rules for the plaintiffs in this case, it would eliminate health insurance subsidies for 7.5 million low- and moderate-income people in those states, causing most of them to become uninsured when their premiums become unaffordable without financial assistance.









here's how the numbers break down in each state with a federally operated health insurance exchange.

update: june 4 -- the numbers displayed on this map are derived from a report that counted health insurance exchange enrollment as of feb. 22, which the department of health and human services published on march 10. the department released new data on june 2, detailing enrollment as of march 31. according to the new report, 7.3 million people were covered by plans purchased via the federally operated health insurance exchanges in the 34 states subject to the supreme court ruling, and 6.4 million of them received subsidies. the new report includes additional information about each state, but does not update the calculation of average unsubsidized premiums.
