SIOUX FALL, S.D. (AP) — Gov. Dennis Daugaard says it's up to federal officials to come up with a potential solution for thousands of South Dakotans whose insurance premiums could jump thousands of dollars a year if the U.S. Supreme Court strikes down a key provision of the Affordable Care Act.

Daugaard said recently that he doesn't envision a state fix to preserve financial assistance if the high court decides to scrap premium subsidies for consumers in more than 30 states who get coverage through the federal marketplace.

The lawsuit prompting the decision expected this month argues the way the law is written means subsidies should be limited to people who use state-based marketplaces.

Lisa Carlson of Sanford Health Plan says a court decision removing the subsidies would be "devastating" for South Dakota consumers.
