The expiration of ACA subsidies could trigger a significant disruption in US healthcare, experts warn. As the financial support for Affordable Care Act plans winds down, many Americans may opt for plans with lower monthly costs but much higher deductibles, or abandon coverage altogether. This shift could send ripple effects through the entire system, impacting rural hospitals and people with employer-provided insurance alike.
A KFF analysis projects that the average annual premium for ACA marketplace plans could more than double—rising from about $888 this year to roughly $1,904 in 2026. If subsidies lapse, these premium hikes could push consumers toward less comprehensive options, increasing uncompensated care and straining health providers across the board.
Emma Wager of KFF notes that when a sizable portion of people drop marketplace coverage or become uninsured, the consequences extend beyond individuals and families to the broader healthcare ecosystem.
In 2021, Congress expanded ACA subsidies and enhanced financial assistance during the COVID-19 emergency, leading to a surge in marketplace enrollment. Those enhanced premium tax credits are set to expire at year’s end, despite attempts by Democrats and a small number of Republicans to extend them for three years. A Senate vote on preserving the credits fell short of the 60 votes required to advance.
Alternative Republican proposals, such as expanding health savings accounts and providing up to $1,500 for basic coverage, also failed to pass. Despite these developments, enrollment in ACA plans remains robust, with the Centers for Medicare & Medicaid Services reporting 5.7 million people enrolled during the open enrollment period as of December 5—slightly higher than the previous year.
Policy observers foresee the full impact of subsidy expiration becoming clearer after open enrollment closes on January 15. Natasha Murphy of the Center for American Progress suggests that the first premium payments will reveal who remains insured and who faces gaps in coverage.
A recent KFF survey indicates potential consumer behavior changes if subsidies end: about one-third of the 24 million adults who buy coverage through the marketplace may choose a lower-premium plan with higher deductibles, while roughly a quarter could become uninsured. As premiums rise, healthier individuals may leave the risk pool, leaving a sicker population behind. This dynamic is described by some experts as a potential “death spiral,” where adverse selection undermines sustainability and may lead insurers to reduce offerings or exit the market.
The consequences extend to care access and hospital finances. Higher unpaid care could force rural and small hospitals, which already operate on thin margins, to raise prices for everyone or close their doors. This would further stress patients with employer coverage and could amplify geographic disparities in access to care.
Rural residents may experience even sharper premium increases than urban residents if subsidies end. Paradoxically, many ACA beneficiaries in rural areas support Republican lawmakers who opposed extending the credits, highlighting the nuanced political landscape surrounding the issue. As Emma Wager points out, the intersection of healthcare policy, rural dependency, and political representation means those most affected may also be the groups most closely watching how these policy choices unfold in Congress.
Thought-provoking questions to consider: Do expanded subsidies truly create sustainable coverage for a larger portion of the population, or do they simply delay cost-sharing challenges that will re-emerge later? If a premium rise triggers a decline in healthy enrollees, what strategies could balance affordability with the financial viability of ACA plans? And how should policymakers address the needs of rural communities that rely heavily on ACA coverage while navigating a polarized political environment?
