WASHINGTON — Trump administration officials on Friday finalized regulations aimed at making it more difficult to enroll in health insurance through the Affordable Care Act.

The rules will limit the time frame for people to sign up for health insurance through the exchanges and cancel a monthly opportunity for people with incomes below 150% of the federal poverty line to enroll, among other changes.

The rule comes as Republicans in Congress eye cuts to Medicaid that will likely result in millions of people losing the health insurance they receive through the program for low-income and disabled people.

The ACA currently provides coverage to roughly 45 million Americans either through the individual health plan marketplace or expanded Medicaid coverage. It’s become a major source of revenue for some health insurers, including Centene Corp. and Oscar Health Inc.

Congressional budget analysts have estimated the new limits will cause 1.8 million additional people to become uninsured if they are imposed over the next decade. However, the new regulations only apply to 2026.

Congressional Republicans had already planned to make the ACA regulations the Trump administration had proposed into law, saving the federal government billions to help pay for President Donald Trump’s tax cut legislation.

But finalizing the regulation now could complicate lawmakers’ budget math, shaving billions of dollars off of savings that lawmakers planned to use to pay for tax cuts. One provision to codify the regulations was estimated to save the federal government more than $6 billion in 2026 alone.
