The Trump administration is shortening the Affordable Care Act (ACA) enrollment period by two weeks, so that starting in the 2027 plan year, the federal marketplace will only be open from November 1 to December 31.[1] These changes are expected to reduce average market premiums by about 5% and save taxpayers about $12 billion over the next year.[1] However, according to the Centers for Medicare and Medicaid Services (CMS), up to 1 million people may lose their insurance as a result of these measures.[1] It will eliminate the monthly option for low-income individuals, impose restrictions on income verification, and ban insurance for DACA recipients.[1] The new rules limit the inclusion of gender-affirming care in plans.[1] Congress is debating whether to include these changes in the Republican budget bill, which would make it harder to repeal.[1] For 2026, they are temporarily introducing a $5 premium for those continuing the plan from the previous year.[1]
