More than a dozen states and the District of Columbia filed a motion on Thursday to intervene in the appeal of a lawsuit targeting the ACA’s cost-sharing reduction (CSR) subsidies. The lawsuit was originally brought by the U.S. House of Representatives against the Obama administration, which the Trump administration must now deal with. The Kaiser Family Foundation has estimated that the average premiums for silver plans sold on the ACA exchanges would increase by about 19% to compensate for insurers’ lack of funding without the CSR payments. The Trump administration and the House are set to update the court on Monday on how they plan to proceed with the case.
