Children’s Health Insurance Program (CHIP)

A summary of 10 of the major health coverage and financing provisions of the current Build Back Better Act, with discussion of the potential implications for people and the federal budget.

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.

KFF’s new analysis examines how state coverage changes and expansions in Medicaid and CHIP eligibility for children may help to bolster coverage following the unwinding of the continuous enrollment provision.

Since 2000, KFF’s Program on Medicaid and the Uninsured has issued regular updates examining changes and trends in the eligibility rules, enrollment and renewal procedures and cost-sharing practices in Medicaid and CHIP. Those reports are compiled here.

A KFF survey of state Medicaid officials examines state Medicaid and CHIP eligibility, enrollment, and renewal policies in place as of January 2025 as states return to routine operations following the unwinding of the continuous enrollment provision. The survey finds that states have broadly adopted policy and system changes to automate and improve the accuracy and efficiency of Medicaid enrollment and renewal processes and provides a baseline of state policies ahead of potential changes to the program.

As Congressional Republicans and President Trump search for trillions of dollars in cuts to mandatory federal spending that could help offset the cost of extending expiring tax cuts, this brief analyzes current support from the federal government for health programs and services, including both spending and tax subsidies as context for those federal budget discussions.

At the start of 2025, many issues are at play that will affect Medicaid coverage, financing, and access to care. While Medicaid was not discussed much on the campaign trail, Congress may consider big changes as part of tax and spending debates and the Trump administration may make changes to Medicaid through executive actions. Amid the potential changes, this brief highlights ten key things to know about Medicaid.

This issue brief compares the demographics, health status, access to care, and coverage affordability of Medicaid/CHIP children with special health care needs to those with private insurance and those who are uninsured. Medicaid plays a key role for children with special health care needs by making coverage affordable and covering services that private coverage typically does not. Consequently, legislative proposals that would cap and reduce federal Medicaid funding may pose a particular risk to children with special health care needs and their providers. A companion brief describes Medicaid’s role for children with special health care needs.

The 22nd annual survey of state Medicaid and CHIP programs officials conducted by KFF and the Georgetown University Center for Children and Families in May 2024 presents a snapshot of actions states have taken to improve systems, processes, and communications during the unwinding, as well as key state Medicaid eligibility, enrollment, and renewals policies and procedures in place as of May 2024. The report focuses on policies for children, pregnant individuals, parents, and other non-elderly adults whose eligibility is based on Modified Adjusted Gross Income (MAGI) financial eligibility rules.
