ACA Enrollment Drops: Impacts of Subsidy Discontinuation

Recent state enrollment data indicates substantial potential coverage reductions for the Affordable Care Act (ACA). This development stems from Congress's decision not to extend the enhanced subsidies that previously bolstered ACA enrollment. States like Arkansas, Colorado, Maryland, Massachusetts, New Mexico, and New York have noted a trend where individuals are either canceling their plans or failing to pay premiums for 2026 coverage, as per analysis by Georgetown University.

Currently, federal officials have released only initial sign-up data from the open enrollment period. This includes automatic plan renewals at the end of 2025. During the 2026 enrollment period, there was a notable decline of 1.2 million sign-ups, reflecting a 5 percent drop from the previous year—the most significant decrease since the marketplaces began in 2014.

Georgetown researchers Stacey Pogue and Sabrina Corlette caution against viewing initial enrollments in isolation, emphasizing the need to assess post-billing cancellations by policyholders. Market analysts predict a total reduction of approximately 5 million in 2026 ACA marketplace enrollments, with further declines expected in 2027 due to legislative and potential regulatory changes.

The discontinuation of enhanced premium subsidies has intensified financial pressures on plan participants, leading to increased health care costs. State exchanges report a 24 percent rise in plan cancellations since March 2025. Middle-income individuals, previously benefiting from premium tax credits, are notably affected, resulting in higher coverage drops. In contrast, low-income enrollees, safeguarded by state subsidies, have shown lower cancellation rates.

Maryland, for instance, recorded a 13 percent drop in enrollments from January to April, a significant increase from the 3 percent reduction last year. Arkansas experienced a 16 percent decline, double the rate in 2025. Massachusetts saw a 14 percent decrease, exceeding last year's 6.7 percent. New Mexico witnessed an 8 percent reduction, compared to just 0.5 percent the previous year.

Pogue and Corlette highlight that although some reduction is typical, the current decrease is noteworthy compared to previous years. They advise caution, noting that while the data reflects a limited number of states, it may indicate broader national trends.
