Speculation swirls around what happens if federal subsidies go away

“New language in contracts between the CMS and insurers operating on HealthCare.gov is grabbing attention, with some calling it an admission by the government that it might lose upcoming court battles dealing with insurance subsidies on the health portal and others saying the new wording is just a practical precaution.
The new language appears to allow insurers to stop offering their plans should federal premium subsidies disappear. A number of cases regarding the legality of the subsidies in states without their own exchanges are now working their way through the courts.
The language says, “CMS acknowledges that (the insurer) has developed its products for the (federal exchange) based on the assumption that (advance payments of the premium tax credit) and (cost-sharing reductions) will be available to qualifying enrollees. In the event that this assumption ceases to be valid during the term of this agreement, CMS acknowledges that issuer could have cause to terminate this agreement subject to applicable state and federal law.””
