Vice President JD Vance on Wednesday unveiled the Trump administration’s most aggressive move yet in the Medicaid fraud crackdown: a $1.3 billion deferral of Medicaid funding to California, and confirmation that Minnesota has permanently lost $112.7 million in federal reimbursements after a review of 14 high-risk areas of its Medicaid programme. The announcements, from an anti-fraud task force Vance chairs, put two of the country’s biggest Medicaid programmes on notice, and warned every other state that failing to investigate fraud could cost it federal money. The administration also ordered a six-month freeze on some new Medicare enrolments.

Key Points

• Vance announced on Wednesday, November 11, 2026, a $1.3 billion deferral of Medicaid funding to California — which CMS Administrator Dr. Mehmet Oz called the largest ever made.
• Minnesota permanently lost $112.7 million in Medicaid reimbursements for the quarter ending September 30, 2025, after a federal review of 14 high-risk areas.
• The $112.7 million is a permanent disallowance, not a freeze: Minnesota must claw back money already paid, though about $131 million in frozen funds will be released.
• The administration also ordered a six-month freeze on some new Medicare enrolments, warning states to investigate Medicaid fraud or risk losing funding.
• Minnesota awaits decisions on about $400 million more in later quarters; the administration says it has approached at least five states with fraud investigations.

What Happened

Vance announced the steps as part of the administration’s anti-fraud initiative, run through a task force he heads. The centrepiece is the $1.3 billion deferral of Medicaid funding to California. Dr. Mehmet Oz, administrator of the Centers for Medicare & Medicaid Services (CMS), called it the largest the agency has ever made. A deferral holds money back while the federal government reviews whether the spending was proper — it is not, by itself, a permanent loss.

The Minnesota decision is sharper. CMS formally denied the state $112.7 million in Medicaid reimbursements for the quarter ending September 30, 2025, in a disallowance notice sent on Friday, November 6. A disallowance is permanent: the money will not be paid, and Minnesota must claw back payments already made to providers. CMS said about $131 million in frozen funds will be released.

The $112.7 million sits inside about $550 million in frozen Minnesota Medicaid money: a $259 million February deferral plus $91 million and $199 million in suspensions. Minnesota awaits decisions on roughly $400 million more for later quarters. The administration had already halted about $243 million to Minnesota before this latest action.

Background: How the Fraud Fight Reached This Point

The crackdown has been building for months. Vance chairs the Task Force to Eliminate Fraud, first convened in March 2026. On Thursday, October 29, federal and state agents searched two Twin Cities autism centres — Iska Inc. and Bright Horizon Therapy Center — as part of a Medicaid fraud probe. The next day, FBI Director Kash Patel, Treasury Secretary Scott Bessent, CMS Administrator Oz and FTC Chairman Andrew Ferguson charged four people in a $41 million Minnesota healthcare fraud scheme.

That case sits in the shadow of the $250 million Feeding Our Future scandal. The November announcements extend that approach to California, the largest Medicaid programme in the country, and to Medicare. Federal health money still flows — CMS recently awarded $10 billion in rural health funds to all 50 states — but increasingly with conditions.

Medicaid Fraud Crackdown Widens to More States

The administration says it has approached at least five states with fraud investigations, and the message to governors was blunt: investigate Medicaid fraud or lose funding. The California deferral shows the threat is not theoretical. At $1.3 billion, it is the largest single deferral CMS has ever imposed, landing on the state with the biggest Medicaid programme in the United States.

The six-month freeze on some new Medicare enrolments adds a second front. Medicare enrolment freezes are rare, and even a partial one signals the administration is willing to use the federal health programmes themselves as an enforcement tool. What makes Minnesota different is permanence: a deferral can be reversed if a state proves its claims, but a disallowance cannot — the $112.7 million is gone.

Reactions and Quotes

Oz called the California deferral a record — the largest ever made, a figure meant to be noticed in every state capital. In Minnesota, the reaction was alarm. State Medicaid director John Connolly wrote to staff on Tuesday, November 10, that the $112.7 million loss is “deeply concerning for the more than one million Minnesotans who depend on Medicaid.” His warning captures the tension at the heart of the crackdown: the money at stake pays for care for more than a million people in Minnesota alone, and tens of millions more in California.

Why It Matters

Medicaid is the largest source of health coverage for low-income Americans. California runs the biggest programme in the country; Minnesota’s covers more than a million people. When Washington holds back $1.3 billion from one and permanently denies $112.7 million to the other, the effects reach hospitals, clinics, providers and patients — not just state budgets.

The Minnesota clawback is the sharpest edge: providers paid for services in the quarter ending September 30, 2025, may now have to return that money, even though the services were delivered. That kind of retroactive recovery strains small providers and safety-net clinics first. Related coverage: Nebraska Medicaid work rules left a cancer patient without coverage.

What Happens Next

Minnesota’s immediate task is the clawback: recovering $112.7 million already paid to providers, while waiting for CMS decisions on roughly $400 million more for later quarters. Those decisions will determine whether the total permanent loss grows beyond this week’s figure.

California faces a different clock: a deferral is a review, not a verdict. If CMS is satisfied, the $1.3 billion can be released; if not, some or all of it could follow Minnesota’s money into disallowance. The six-month Medicare freeze runs into the spring, and with at least five states already approached, further announcements are likely.

Frequently Asked Questions

What is a Medicaid deferral?
A deferral is a temporary hold on federal Medicaid payments while CMS reviews whether the spending was proper. The money can be released if the state proves its claims — unlike a disallowance, a permanent denial.

Why did Minnesota permanently lose $112.7 million?
CMS issued a disallowance notice on November 6, 2026, after reviewing 14 high-risk areas of Minnesota’s Medicaid programme. The state must claw back money already paid.

How much Minnesota Medicaid money is frozen in total?
About $550 million: a $259 million February deferral plus $91 million and $199 million in suspensions. About $131 million will now be released, and Minnesota awaits decisions on roughly $400 million more.

What does the six-month Medicare freeze do?
A six-month freeze on some new Medicare enrolments. The administration has not said which categories are affected, and the freeze is separate from the Medicaid actions against California and Minnesota.

Which states are under investigation?
At least five states, the administration says. Only California and Minnesota have been named in connection with this week’s announcements.
