Health plans would likely feel the financial hit if the courts ultimately strike down Obamacare’s cost-sharing subsidies. That’s because those payments go directly to insurers to make up for lower payments from their poorest customers.

A federal court ruled today that the Obama administration has been improperly funding the cost-sharing subsidies. The ruling is stayed pending appeal, so there will be no immediate fallout for health plans.

But at stake is approximately $175 billion over a decade that insurers would receive to subsidize their Obamacare customers. Cost-sharing subsidies are available to enrollees with incomes below 250 percent of the federal poverty level who enroll in silver plans. They’re designed to reduce out-of-pocket costs when those individuals access medical care.
