A coalition of organizations ranging from the health care union 1199/SEIU to the Business Council sent a letter Friday to the state’s House delegation urging them to push for subsidies made available under the Affordable Care Act that President Trump has threatened to discontinue.

The money, known as cost-sharing reduction, or CSR, payments, are subsidies to insurance companies that help cover out-of-pocket costs for low-income people.

“If the CSRs are discontinued and the State is unable to modify rates, it would disrupt the stability of the New York marketplace,” the groups wrote in the letter. That disruption, along with the loss of significant Essential Plan funding, would result in more uninsured New Yorkers, more financial instability for providers and higher costs for all.”

Signing on to the letter Greater New York Hospital Association, Citizen Action, the New York State Nurses Association and the state AFL-CIO, among others.

The future of the funding is now the subject of litigation as well, with Attorney General Eric Schneiderman and California Attorney Xavier Becerra being given approval this week to defend the payments in court. The case dates back to the Obama administration when House Republicans challenged the legality of the payments. The Trump administration has signaled it will not continue to defend the case in court.

Trump’s threat to yank the subsidy payments comes after the failure of Republicans in Congress to approve legislation that would repeal the broad strokes of the Affordable Care Act. Some lawmakers now are discussing smaller fixes to the law that would stabilize markets in a bid to gain Democratic votes for the potential legislation.
