Medicaid Cuts Are Now Law: What the 'One Big Beautiful Bill' Actually Does to Your Health Coverage

What Is Medicaid and Who Uses It?

Medicaid is the government health insurance program for people with low incomes. It covers 1 in 5 Americans — about 79 million people. That includes children (nearly half of all Medicaid enrollees), pregnant women, seniors in nursing homes, people with disabilities, and low-income adults. It is not a welfare program for people who choose not to work: 60% of adult Medicaid enrollees who can work are already working, and most of the rest are caregivers, students, or people with serious health conditions.

What the Law Actually Does

On July 4, 2025, President Trump signed the 'One Big Beautiful Bill' (Public Law 119-21) into law. The Congressional Budget Office — the nonpartisan federal agency that scores the cost of legislation — estimates the law will cut $911 billion from Medicaid over the next 10 years. Here are the four main ways it does that:

How Many People Will Lose Coverage?

The CBO's October 2025 supplemental cost estimate — the most detailed official analysis of the law's health effects — projects that 7.5 million more Americans will be uninsured by 2034 as a direct result of these Medicaid cuts. That is not a projection of people who 'might' lose coverage. That is the CBO's central estimate of people who will lose coverage and not find it elsewhere.

"CBO estimates that, on net, about 7.5 million more people would be uninsured in 2034 under this legislation than under prior law."

The Work Requirements: What the Evidence Actually Shows

Work requirements are the single largest cut in the law — $326 billion. The stated goal is to encourage employment. But the CBO found something striking about what they actually do:

"CBO estimates that the work requirements would not have any meaningful impact on the number of Medicaid enrollees working."

In other words: the cuts happen, but the employment doesn't increase. Why? Because most people who lose coverage under work requirements were already working — they just couldn't navigate the paperwork. Arkansas tried work requirements in 2018. Within months, 18,000 people lost coverage. A Harvard study found that nearly all of them were already working or exempt — they lost coverage because of administrative barriers, not refusal to work. The program was struck down by a federal court.

Which States Are Hit Hardest?

KFF's analysis of the CBO's state-by-state estimates shows that the cuts are not evenly distributed. States that expanded Medicaid under the ACA — and therefore have more enrollees — face the largest absolute cuts. But some smaller states face the largest cuts as a percentage of their current federal Medicaid funding:

The Timeline: When Do the Cuts Hit?

The law is deliberately backloaded — 76% of the $911 billion in cuts ($694 billion) hits in the final five years, 2030–2034. This is a common legislative technique: the savings look smaller in the near term, but the long-term impact is enormous. Here is the key date every Medicaid enrollee needs to know:

• January 1, 2027: Work requirements take effect. If you are on Medicaid and between 19–64, you will need to document 80 hours/month of qualifying activity or lose coverage.
• Every 6 months starting in 2026: States begin more frequent eligibility re-checks. You may receive paperwork asking you to re-verify your income and household status.
• 2030–2034: The largest cuts hit as the reduced federal match rates fully phase in.

What You Can Do Right Now

If you or someone you know is currently on Medicaid, here are the most important steps to take before January 1, 2027:

• Keep your contact information updated with your state Medicaid office. Most people lose coverage due to returned mail, not ineligibility.
• Respond to every letter from Medicaid immediately. Under the new 6-month re-verification rule, missing a letter can mean losing coverage.
• If you work, document it now. Keep pay stubs, employer letters, or records of volunteer hours. You will need to prove 80 hours/month starting January 2027.
• If you are a caregiver, student, or have a disability, you may be exempt from work requirements. Contact your state Medicaid office or a local navigator to confirm your status.
