The federal government could face a $2.3 billion net increase in costs if the Trump administration ends certain ObamaCare insurer payments, according to a study released Tuesday.

Research from the Kaiser Family Foundation showed that while ending the insurance reimbursements for companies, known as cost-sharing reduction (CSR), may save the government $10 billion in the short term, it could also cost another $12.3 billion in tax credits.

Insurers who stay in the ObamaCare exchanges are likely to up their premiums to compensate for losing the CSR payments. This in turn would increase the government's tax credits, according to the study.

“The increased tax credits would completely cover the increased premium for subsidized enrollees covered through the benchmark plan and cushion the effect for enrollees signed up for more expensive silver plans,” Kaiser said in its study.

President Trump has threatened to end the payments as a way of letting ObamaCare collapse into a "death spiral."

Trump has also floated keeping the ObamaCare payments as a concession to Democrats in exchange for funding in a new spending bill for his proposed wall along the southern border. But the office of Senate Minority Leader Charles Schumer Chuck SchumerMcConnell accuses Democrats of sowing division by 'downplaying progress' on election security Warren, Schumer introduce plan for next president to cancel ,000 in student debt Schumer lashes out at Trump over 'blue states' remark: 'What a disgrace' MORE (D-N.Y.) last week dismissed the proposal from White House budget chief Mick Mulvaney as a “nonstarter.”

But the Kaiser study said ending the payments would cause insurers to “face significant revenue shortfalls this year and next year.”

“Extrapolating to the 10-year budget window (2018-2027) using CBO’s projection of CSR payments, the federal government would end up spending $31 billion more if the payments end,” the study said.

Lawmakers have until midnight Friday to pass a new spending bill to keep the government funded and avoid a shutdown.
