In 2025, about one in three ACA enrollees said they would be “very likely” to look for a lower-premium Marketplace plan If their premium payments doubled.
Adults ages 50 to 64 are disproportionately affected by the expiration of ACA enhanced premium tax credits because they make up a large number of Marketplace enrollees and premiums rise with age.
Following the expiration of the enhanced premium tax credits for people with Affordable Care Act (ACA) Marketplace plans, a new KFF follow-up survey of the same Marketplace enrollees KFF surveyed in 2025 finds half (51%) of returning enrollees say their health care costs are “a lot higher” this year compared to last year, including four in 10 who specifically say their premiums are “a lot higher.”

Health coverage enrollment through the ACA marketplaces now exceeds 24 million people, a dramatic increase in recent years fueled largely by enhanced premium aid. With the subsidies set to expire at the end of this year, Congress and the Trump Administration will be faced with a choice of whether and how to extend the subsidies, alongside broader discussion about the budget. On February 10, KFF’s Larry Levitt moderated a 45-minute virtual discussion with an expert panel to explore these questions and more about the future of the ACA.
This analysis and interactive map illustrate how much more enrollees in Affordable Care Act (ACA) Marketplace plans would pay in premiums at the congressional district level if the enhanced subsidies were to expire in 2026 as under current law. The tool presents scenarios for an older couple who would lose subsidy eligibility due to their income level and for a single person with a $31,000 income. It also presents net average premium payment increases in each district in states that use Healthcare.gov.
In a new column, KFF President and CEO Drew Altman discusses what President Trump’s decision to pull back the broad freeze in federal grant funding might portend for his response to future policies in health that prove controversial or unpopular.
HealthCare.gov insurers denied nearly one out of every five claims (19%) submitted for in-network services and an even larger share (37%) share of claims for out-of-network services in 2023, a new KFF analysis finds.
This brief analyzes federal transparency data released by the Centers for Medicare and Medicaid Services (CMS) on claims denials and appeals for non-group qualified health plans (QHPs) offered on HealthCare.gov in 2023. It finds that HealthCare.gov insurers denied nearly one out of every five claims (19%) submitted for in-network services. Information about the reasons for denials is limited, and few consumers appeal claims denials.

With the incoming Trump administration and Republican-led Congress looking to ways to reduce federal spending, this Poll finds that the Medicare and Medicaid programs remain broadly popular, and more people favor more spending on those programs than less spending. Among potential actions on health, the public sees price transparency and limiting chemicals in food as top priorities. Few say so about cuts to Medicaid and restrictions on abortion.
A new KFF analysis finds that there were 44 million people enrolled in health coverage through the Affordable Care Act’s Marketplaces and its expansion of the Medicaid program in 2024. That represents about 1 in every 6 people under age 65, or 16.4%.
In 2024, ACA enrollment (including Marketplace, Medicaid expansion, and BHP) reached 44 million, or 16.4% of the nonelderly U.S. population. From 2020-2024, enrollment in ACA coverage increased by over 60%.
