State Health Facts is a KFF project that provides free, up-to-date, and easy-to-use health data for all 50 states, the District of Columbia, and the United States. It offers data on specific types of health insurance coverage, including employer-sponsored, Medicaid, Medicare, as well as people who are uninsured by demographic characteristics, including age, race/ethnicity, work status, gender, and income. There are also data on health insurance status for a state's population overall and broken down by age, gender, and income.
The ACA Marketplace Open Enrollment season begins November 1, and with it comes looming changes to the enhanced premium tax credits, increases in out-of-pocket premium payments, new Marketplace eligibility rules, and more. Read our analysis of what these and other changes could mean for new and returning enrollees.
In his latest column, President and CEO Drew Altman discusses how, with nearly half, or about 10 million MAGA supporters and Republicans receiving coverage through the ACA Marketplaces, the policy changes and cuts being considered by Republicans to the Marketplaces will directly affect their own voters. Altman writes: "Republicans are no longer interested in repealing the ACA but seem comfortable shrinking it significantly if they can, so long as they don’t touch protections for pre-existing conditions, which is now a political third rail."
Most (58%) people with health insurance say they encountered at least one problem using their coverage in the past year, with even larger shares of people with the greatest health care needs reporting such problems, finds a new KFF survey of consumer experiences with health insurance.
The survey finds nearly six in 10 people with health insurance experienced a problem using their insurance in the past year, with even larger shares reporting problems among people who are sick or who have mental health needs. It includes data for people with different types of coverage, including employer, Marketplace, Medicare and Medicaid, and also examines affordability issues and mental health access.
This analysis estimates that 1.4 million uninsured individuals in the ten states without Medicaid expansion, including many working adults, people of color, and those with disabilities, remain in the "coverage gap," ineligible for Medicaid or for tax credits that would make coverage through the Affordable Care Act's Marketplaces affordable to them.
Nationwide, an estimated 52 million nonelderly adults live with mental illness, and Medicaid covers nearly one in three (29%) of them, or about 15 million adults. More than 1 in 3 Medicaid enrollees has a mental illness. Mental health treatment rates for Medicaid adults are higher than or similar to those with insurance.
This brief provides five key facts on Medicaid and immigrants as context for understanding the potential impacts of policy changes under the Trump administration.

In Medicare Physician Fee Schedule Final Rules from recent years, the administration made changes to Medicare payment policies for certain dental services, in addition to other payment and policy changes. The 2023 rule clarified CMS’s interpretation of when medically necessary dental services can be covered and codified certain payment policies, and the 2023, 2024, and 2025 rules define new clinical scenarios for which Medicare payment can be made for dental services. This brief describes current law related to coverage and payment for dental services under Medicare and the rationale for changes to current policy, explains changes to dental payment and coverage included in these rules, and discusses the impact on Medicare and beneficiaries. While these changes are projected to benefit a small number of Medicare beneficiaries, they do not represent a broad expansion of Medicare coverage of dental services.
