In his latest column, president and CEO Drew Altman discusses why debate about extending the ACA enhanced tax credits set to expire this year has been slow to develop, and why it could matter to Republicans politically if the tax credits are not extended.

Enrollment in Affordable Care Act (ACA) Marketplace health plans reached a record 24.3 million people, more than double the total in 2020, with most of the growth occurring in states won by President Trump in the 2024 election, a new KFF analysis finds.  Almost all states have seen increases in…

This analysis of enrollment in Affordable Care Act (ACA) Marketplace health plans finds a record 24.3 million people enrolled in 2025, more than double the total in 2020, with most of the growth occurring in states won by President Trump in the 2024 election. In six states, enrollment more than tripled from 2020 to 2025: Texas, Mississippi, West Virginia, Louisiana, Georgia, and Tennessee.

This analysis looks at the individual market enrollees who make at least four times the federal poverty level who would no longer be eligible for any tax credits if the current ACA Marketplace enhanced subsidies expire at the end of this year. Compared to other people with similar incomes, these enrollees are more likely to be early retirees, self-employed and living in rural areas.

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.

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. The analysis examines the main source of publicly available data on claims denials and appeals for…

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.
