Federal data indicates that approximately 3 million fewer people held Affordable Care Act (ACA) health insurance plans in February compared to the same period in 2025. According to the U.S. Department of Health and Human Services (HHS), total enrollment dropped from 22.1 million to 19.2 million. While the agency points to a crackdown on fraudulent “phantom” enrollments, health analysts contend that the expiration of federal subsidies—which led to sharp premium increases—is the primary driver behind the coverage loss.
Why is ACA enrollment declining?
The decline in enrollment is largely tied to a significant shift in affordability. While HHS suggests that recent federal efforts to remove fraudulent or unauthorized “phantom” enrollments account for a portion of the reduction, independent analysts offer a different perspective. Cynthia Cox, a vice president and director of the ACA program at the healthcare research nonprofit KFF, states that the loss of coverage aligns with the January 1 expiration of federal subsidies.
This expiration forced many enrollees to face double or triple-digit increases in monthly premiums. According to KFF, survey data confirms that real people left their plans specifically because they could no longer afford the increased costs.
The ACA marketplace includes a “nonpayment grace period.” Because of this, the February figures are particularly significant; they represent the first official look at enrollment after the grace period for unpaid bills expired, revealing how many people were forced out of the system due to inability to pay.
What are the projected trends for the remainder of the year?
Industry projections suggest that the downward trend in ACA participation is likely to continue. KFF analysts expect total enrollment to potentially drop to 17.5 million by the end of the year. This represents a substantial contraction for the government’s flagship subsidized health insurance program for working-age people who do not qualify for Medicaid. In recent years, ACA plans have become a popular choice for gig workers, farmers, ranchers, hairstylists, and others without health coverage through an employer.
The shift is already visible in earlier government estimates. In January, federal data showed 800,000 fewer people enrolled compared to the previous year—a milestone marking the first time in four years that enrollment had dipped during the active shopping window.
How do premium costs impact voter concerns?
The financial strain on households is becoming a central theme in the political landscape. The expiration of the subsidies was the subject of intense debate in Congress last fall, with both Democratic and some Republican lawmakers advocating for their renewal. With healthcare affordability identified by voters as a top concern ahead of the November elections, the expiration of these financial supports remains a high-stakes issue.
Pro Tip: Managing Plan Costs
If you are currently enrolled in an ACA plan, verify your eligibility for any remaining state-level subsidies or cost-sharing reductions. Review your premium invoices carefully to ensure you are aware of any upcoming rate adjustments, as the marketplace remains sensitive to federal policy changes.
