The Trump administration plans to shorten the Affordable Care Act (ACA) enrollment period, ending it on December 15 -- one month earlier than the previous deadline. The Centers for Medicare and Medicaid Services (CMS) announced the change, citing concerns over "improper enrollments" that have increased taxpayer costs. CMS also plans to tighten eligibility for special enrollment outside the standard sign-up window and require additional income verification, though details remain undisclosed.

Since its 2010 launch, Obamacare has provided subsidized health insurance to 49.4 million Americans, with a record 20.8 million enrollees in 2024. CMS stated that new measures will ensure individuals are not enrolled without consent. Additionally, gender-affirming care will be classified as non-essential for insurers offering ACA marketplace plans. The agency also confirmed that undocumented immigrants under the Deferred Action for Childhood Arrivals (DACA) program will no longer qualify for coverage.

The move aligns with the administration's broader efforts to reform the ACA. Critics argue that these restrictions could limit access to healthcare for vulnerable populations, while supporters claim they will curb fraudulent enrollments and reduce government spending. CMS has not yet provided further clarification on how these measures will be enforced.
