It's also unclear what will happen to rates for next year. Insurers in Illinois already have committed to their rates, proposing average increases of 16 to 37 percent next year for the lowest-priced plans on the exchange. In many cases, they attributed those jumps partly to the uncertainty surrounding cost-sharing reduction subsidies. It's possible some states might now allow insurers to refile their rates in light of the end of the subsidies, Jost said.
