Impact of Federal Subsidy Changes on ACA Enrollment

The Trump administration has attributed the reduction in Affordable Care Act (ACA) enrollment to intensified efforts to eliminate fraud. State insurance exchanges and policy analysts, however, argue that rising premiums resulting from the end of certain federal subsidies might be a more significant factor.

As of March, federal data shows a decrease in ACA enrollment by 1.2 million people, totaling 24.3 million participants nationwide. Administration officials, including Health and Human Services Secretary Robert F. Kennedy Jr., stated that enhanced verification processes have rightly removed individuals not genuinely eligible for coverage.

At an April congressional hearing, Kennedy reinforced this stance, stating, "The only people who lost coverage were people who were never entitled to coverage." Yet, representatives from state-managed exchanges claim that affordability issues heavily influence enrollment declines, pointing to the lapse of enhanced subsidies in early 2026 as a critical factor driving premium increases.

The Vermont Department of Health Access emphasized, "Fraud is not a driver of coverage loss. The primary driver is affordability." An analysis by KFF News reveals that average monthly premiums rose by 58% in 2026. Deductibles increased by 37%, reaching $3,786, which is likely to contribute to ACA enrollment potentially dropping to 17.5 million by year's end, a significant drop from 22.3 million in 2025.

Data indicates that those slightly above the previous subsidy threshold significantly contributed to the decline. Individuals earning between 400% and 500% of the federal poverty line made up 27% of the enrollment decrease, despite previously representing only 3% of marketplace enrollments.

Specific demographics in various states have experienced notable drop-off rates. Colorado reported declines among rural populations and those over 55, while Massachusetts saw many legally present immigrants lose access due to regulatory changes. Meanwhile, some consumers opted for bronze-level plans with lower premiums but higher deductibles, as seen in Rhode Island, where bronze plan enrollment rose by 38%, despite an overall 20% drop in state marketplace enrollment.
