The independent source for health policy research, polling, and news.
KFF’s policy research provides facts and analysis on a wide range of policy issues and public programs.
KFF designs, conducts and analyzes original public opinion and survey research on Americans’ attitudes, knowledge, and experiences with the health care system to help amplify the public’s voice in major national debates.
KFF Health News is a national newsroom that produces in-depth journalism about health issues and is one of the organization’s core operating programs.
States expect national Medicaid enrollment to decline by about 4% and state Medicaid spending to rise by 7% in fiscal year (FY) 2025.
This brief presents facts about Medigap, including the characteristics of Medicare beneficiaries with a Medigap policy, variation in Medigap enrollment by state, and Medigap premiums.
These fact sheets lay out the health care landscape in every state, providing data on a variety of health care topics that may be the focus of policy debates in the 2024 election. Topics include health costs; women’s health policy, including state abortion, contraception and maternity laws and policies; health coverage, including the Affordable Care Act, Medicare and prescription drug coverage, Medicaid, and employer-sponsored insurance; gender affirming care; and basic information on health status, population and income.
This brief examines the share of Medicare beneficiaries who reviewed their coverage and compared plans during the open enrollment period for 2022 (that takes place in the Fall of 2021), and who made use of Medicare’s official information resources, as well as variations by demographic groups. Overall, nearly 7 in 10 Medicare beneficiaries did not compare their own source of Medicare coverage with other Medicare options offered in their area.
With open enrollment less than a month away, a new KFF analysis suggests that the vast majority of the nation’s 67 million Medicare beneficiaries will not shop around among the coverage options for 2025 or switch plans. It’s a decision that could have a significant impact on enrollees’ coverage and costs.
Over 25 million people were disenrolled from Medicaid and over 56 million had their coverage renewed, according to KFF’s analysis of the outcomes of the Medicaid unwinding, which nearly all states have now completed.
Using data from the KFF Medicaid Enrollment and Unwinding Tracker, this analysis reports data on unwinding renewal outcomes through June 2024 and examines Medicaid enrollment changes from February 2020 through May 2024, the most recent federal enrollment data available, nationally and across states.
This policy watch uses unwinding data collected through KFF’s Medicaid Enrollment and Unwinding Tracker to examine how national-level renewal outcomes changed over the course of unwinding, including changes in the share of people who had their coverage renewed or were disenrolled from Medicaid each month.
In 2024, more than half (54%) of eligible Medicare beneficiaries are enrolled in Medicare Advantage plans. This brief provides current information about Medicare Advantage enrollment, by plan type and firm, and shows how enrollment varies by state and county.
