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.
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.
This policy brief uses the most recent available data to examine the patterns of health coverage for young adults after they turn 19 and typically are no longer eligible for Medicaid or the Children's Health Insurance Program (CHIP).
As Congress weighs spending cuts and other changes to Medicaid, more than half (54%) of the public say they are worried significant reductions in federal Medicaid spending would negatively affect their family’s ability to obtain and afford health care, a new KFF Health Tracking Poll finds.
This analysis examines the potential impacts on states and Medicaid enrollees of implementing a per capita cap on the federal share of Medicaid spending for the ACA Medicaid expansion population only, which is another proposal that has been discussed by members of Congress.
The Medicare drug price negotiation program could improve coverage of drugs selected for negotiation for Medicare beneficiaries because the law requires all Medicare Part D plans to cover each of the selected drugs, including all dosages and forms, when negotiated prices take effect.
This analysis examines 2026 Medicare Part D formulary coverage of drugs selected for negotiation to measure the effect of the IRA's coverage requirement.

This report examines similarities and differences in federal consumer protection standards for Medicare Advantage (MA) plans, Qualified Health Plans (QHPs), and Medicaid Managed Care Organizations (MCOs). It focuses on rules established at the federal level, though some states have chosen to go above the federal minimums and impose additional requirements for QHPs and Medicaid MCOs.
The Affordable Care Act (ACA) has changed access to health coverage for millions of women across the nation, including a provision requiring most private health insurance plans to provide coverage for prescription contraceptives and services.
The Patient Protection and Affordable Care Act (ACA) requires most private plans to provide coverage for women’s preventive health care, including all prescribed FDA-approved contraceptive services, without cost sharing. To better understand how this provision is being implemented by health plans, Kaiser Family Foundation (KFF) staff, with the Lewin Group, reviewed the insurance plan coverage policies for 12 prescribed contraceptive methods (excluding oral contraceptives). This report presents information from 20 different insurance carriers in five states (California, Georgia, Michigan, New Jersey, and Texas) about how they are applying reasonable medical management (RMM) techniques in their coverage of women’s contraceptive services. The different forms of female birth control reviewed in this report include the contraceptive ring, the patch, injections, implants, intrauterine devices (IUDs), and sterilization.
A new Kaiser Family Foundation report released today finds how health insurance carriers are interpreting and implementing the Affordable Care Act's contraceptive coverage requirement varies, limiting contraceptive options for some women.
