Certain insurers must now publicly report specific prior authorization metrics, but the new data offer limited insight, providing no information on what types of services are being approved and denied or why as well as no data on prescription drugs.
Ahead of the 2026 midterm elections, this KFF issue brief examines the role health care has played in previous elections and what that may suggest about its potential role in 2026. KFF polls have consistently found that the cost of health care is an important part of voters’ economic concerns.
In a new column, President and CEO Dr. Drew Altman writes about the "conundrum of health policy ideas" facing Democrats searching for new proposals because of competing, and complex, priorities: rebuilding Medicaid and the ACA after trillion-dollar cuts, reconstructing federal health agencies, and tackling underlying health care costs, when candidates want simple ideas they can campaign on and voters want their costs to come down.
This brief analyzes federal transparency data published by CMS on claims denials and appeals for Marketplace plan offered on HealthCare.gov in 2024, and finds insurers denied 19% of in-network claims. Consumers rarely appeal denied claims.
On the 16th anniversary of the Affordable Care Act’s (ACA) passage, most of the public (61%) view the law favorably, though opinions and debates remain as partisan as ever....As voters continue to grapple with the affordability of coverage and care, the partisan legacy of the ACA will almost certainly figure into debates about health care costs this fall.
In a new column, Dr. Drew Altman, KFF’s President and CEO, discusses the impact of the war in Iran and rising gas prices on voter concerns about health care costs. He writes: “Recently, we saw health care costs rise to the top of the public’s list of economic worries, ahead of food, housing, utility costs and the cost of gas….Expect gas prices to rise and health care costs to fall on the list of affordability worries while the war in Iran lasts, but then to return to the top or near the top when President Trump decides to declare the major hostilities over, the Strait of Hormuz is open, and gas prices come down….health care costs have staying power as one of the top voter concerns.”
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 ten who specifically say their premiums are “a lot higher.”
This KFF survey is a follow-up survey of adults who had ACA Marketplace insurance in 2025. The survey examines the cost concerns and coverage changes that these 2025 Marketplace enrollees are experiencing following the expiration of the enhanced premium tax credits. The survey finds that half of returning enrollees say their health care costs are “a lot higher” and most expect to cut back on basic household expenses to afford coverage.
