Enrollment Declines in Ohio Highlight Impact of ACA Subsidy Expiration

Ohio has experienced the most significant reduction in enrollment for health plans under the Affordable Care Act (ACA), according to federal data highlighted by the Associated Press. This decline follows the cessation of pandemic-era subsidies that were essential for purchasing insurance on ACA exchanges. The expiration of these subsidies led to premium increases for many of the 25.2 million Americans who relied on coverage through these exchanges. National enrollment figures declined by 2.6 million from February 2025 to February 2026, representing approximately a 10% reduction. Ohio faced a more severe impact, with enrollment dropping from nearly half a million in early 2025 to 336,000 recently—a 32.4% decline, equating to a loss of 161,385 enrollees. Oklahoma also saw a substantial decrease of 32.3%. Significant enrollment declines were recorded in neighboring states: Michigan and Indiana each faced over 25% reductions, while Kentucky and West Virginia experienced decreases of 14.3% and 13.1%, respectively. In contrast, Pennsylvania noted a modest 1.2% decline in enrollment. The subsidies' expiration followed Congressional approval of legislation related to extending tax cuts begun during the Trump administration. This was part of broader budget adjustments affecting federal spending on Medicaid and nutrition assistance programs. Although previous attempts to repeal the ACA, commonly known as Obamacare, were unsuccessful, the recent legislative changes have significantly altered the program's landscape. Experts anticipate a rise in the uninsured population due to the subsidy discontinuation. Natasha Murphy, health policy director at the Center for American Progress, notes that while the full impact on the uninsured rate for 2026 remains uncertain, early enrollment data show a downward coverage trend. Murphy highlights that the expiration of premium tax credits, coupled with policy shifts, has made health insurance less affordable, leaving some families without viable options. The changes in Medicaid spending have led some insurers to withdraw from markets in states that expanded Medicaid to cover individuals earning up to 138% of federal poverty levels. For instance, Centene, the largest Medicaid managed care provider in the U.S., has announced its exit from Arkansas's Medicaid program, as reported by the Arkansas Advocate.
