Health Policy 101 is a comprehensive guide covering fundamental aspects of U.S. health policy and programs, including Medicare, Medicaid, the Affordable Care Act, employer-sponsored insurance, the uninsured population, health care costs and affordability, women's health issues, and health care politics. The Health Care Costs and Affordability chapter explores trends in health care costs in the U.S. and the factors that contribute to this spending. It also examines how health care spending varies across the population, the impact of costs on care affordability and individuals' overall financial vulnerability.

In his latest JAMA Forum column, KFF’s Larry Levitt explores how unaffordable health care is in the U.S. in the context of the debate over extending enhanced Affordable Care Act premium tax credits and an upcoming election where affordability will likely be front and center.
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.
This analysis examines early indicators of how the expiration of enhanced premium tax credits has affected effectuated enrollment levels (i.e., enrollment among people who have paid their premiums), plan selections, and out-of-pocket costs in 2026, drawing on plan selection and effectuated enrollment data from the Centers for Medicare & Medicaid Services (CMS) and state-based Marketplace (SBM) Open Enrollment reports, as well as KFF survey data and individual market enrollment estimates from Wakely Consulting Group.
The Affordable Care Act, also called Obamacare, creates several new ways to get health coverage. This fact sheet explains how If you are uninsured and not offered health coverage through your job, you may be able to obtain coverage through Medicaid or through a new health insurance marketplace (or exchange) in your state. It is from our Obamacare & You series.
This short explainer provides an overview of open enrollment and the 2020 individual insurance market, including Affordable Care Act (ACA) marketplaces, for consumers who buy their own plans rather than getting insurance through an employer.
This analysis examines disparities in access to air condition and their implications. It shows Asian-, Black-, and Hispanic-led households are more likely to report not having an air conditioning unit in their home compared to White households.

This analysis estimates that 1.2 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 affordable through the Affordable Care Act's Marketplaces.
On Tuesday, July 21, three experts joined Health Wonk Shop series moderator Larry Levitt in an hour-long discussion of health care affordability. During the discussion, panelists considered affordability from a variety of perspectives, including how to define affordability and the question of affordability for whom, how to measure it, and what can be done to address affordability and the underlying cost of health care.
