$1.3 billion in California Medicaid funds deferred by Trump administration during fraud inquiry

Federal deferral triggers fraud probe

Federal officials announced they will defer $1.3 billion in Medicaid payments to California, citing suspected fraud concerns and questions about state Medicaid spending. CMS Administrator Dr. Mehmet Oz called it the largest Medicaid deferral the agency has ever made, while California officials disputed the administration’s framing.

Vice President JD Vance warned that states could risk federal funding if they do not aggressively investigate Medicaid fraud. The move coincides with a six-month nationwide CMS moratorium on new Medicare enrollments for hospice and home health agencies.

Administration cites home-care anomalies

CMS Administrator Dr. Mehmet Oz said the funding hold is “justified” by unexplained “anomalies” in California’s Medicaid spending. He noted unusually fast growth in home-care costs but acknowledged there were no signs of specific fraud cases documented yet.

Oz demanded officials explain these “outlier” payments. California leaders responded that expanded in-home care was a deliberate policy, keeping people out of expensive nursing homes.

Vice president emphasizes fraud crackdown

Vice President JD Vance, who has led Trump’s anti-fraud task force, announced the $1.3 billion California Medicaid deferral during a White House event. He said the administration is trying to stop taxpayer money from flowing to fraudsters instead of patients who need care.

The administration is expanding its Medicaid and Medicare fraud push nationwide, including warnings to states about Medicaid fraud enforcement. AP reported that officials had also halted about $243 million in Medicaid payments to Minnesota over fraud concerns.

California officials push back

Gov. Gavin Newsom said officials were “attacking programs that keep seniors and people with disabilities OUT of nursing homes”. He noted in-home care costs about $30,000 versus $137,000 in nursing homes, saving $107,000 per person.

Rep. Sydney Kamlager-Dove warned the cuts will “hurt patients, strain providers, and drive up costs.” AG Rob Bonta said the action unfairly targets a Democratic-led state.

Fun fact: Medicare covers hospice only when a patient accepts comfort-focused care instead of treatment meant to cure the terminal illness.

CMS freeze on hospice and home care

CMS announced a six-month nationwide moratorium on new Medicare enrollments for hospice and home health agencies. The agency said the pause is meant to prevent new fraudulent providers from entering Medicare while it intensifies investigations and data analysis.

Provider groups warned that a broad enrollment freeze could affect patient access in areas where demand is growing or capacity is already strained. The National Alliance for Care at Home said fraud enforcement is important but argued that targeted, risk-based oversight would better avoid harming compliant providers.

Details of flagged expenditures

CMS Administrator Dr. Mehmet Oz said California’s Medicaid records generated major red flags and that the state needed to clarify about $630 million in billing, $500 million in home health services, and $200 million in questionable expenditures. Federal officials framed those figures as requiring further explanation, while California officials disputed the fraud allegations.

Oz also alleged that some questioned expenditures were linked to coverage for undocumented immigrants. California officials have pushed back on the administration’s claims and said the state follows applicable coverage rules.

Fun fact: CMS oversees Medicare, Medicaid, the Children’s Health Insurance Program, and the Health Insurance Marketplace.

California’s anti-fraud actions

California moved to restrict new hospice licenses in 2021 after growing concerns about fraud and abuse in the sector. A 2022 California State Auditor report later found weak controls and warning signs of large-scale hospice fraud, particularly in Los Angeles County.

In April 2026, California Attorney General Rob Bonta announced charges against 21 suspects in an alleged $267 million hospice fraud scheme. California officials argue that the state has taken enforcement action and that the federal deferral is punitive and unjustified.

Wider federal investigations

CMS paused $243 million in Minnesota’s Medicaid funding during a fraud probe, and at least five states have faced similar investigations. CMS later acknowledged using flawed data in New York’s case, reinforcing concerns that the administration “tends to attack first and confirm the facts later”.

Policy experts warn that this aggressive approach could ultimately erode public trust in the Medicaid oversight system. Its outcome may set a precedent for future Medicaid enforcement and funding policies.

Political backdrop

Vance pitched the deferral as recouping taxpayer funds, saying he’s clawing back dollars Americans overpaid. Democrats like Sen. Padilla called it “political retribution,” saying it punishes a state that didn’t support Trump.

Republicans call it part of fighting government waste, while Democrats view it as a pretext to cut funding. The dispute is now a campaign issue ahead of the 2026 elections.

Impact on Californians

Many low-income Californians could feel the impact. Rep. Kamlager-Dove said 56% of her constituents rely on Medi-Cal, and some worry providers may face cash flow issues if reimbursements are frozen.

Advocates warn funding delays could force states to shift resources or cut programs. Slower payments may hinder services like In-Home Supportive Services, which keep seniors at home instead of costly nursing facilities.

Possible legal challenges

California officials have signaled possible legal action. AG Bonta said the state could challenge the deferral in court, arguing such cuts may violate federal law. For now, the state is reviewing options.

Legal experts say CMS must follow strict procedures under Medicaid law before suspending funds. If California challenges the decision, courts will decide whether the administration had the authority to withhold these payments.

State Medicaid budget context

California’s Medicaid program is expected to cost about $222 billion in the budget year that starts July 1. The $1.3 billion deferral is less than 1% of that total, but California officials and advocates warn that delayed reimbursements could still affect services for vulnerable residents.

Supporters of the federal action say even smaller amounts of suspected fraud can strain public budgets and undermine trust in Medicaid. Opponents argue that California had planned for those federal reimbursements and that delays could create uncertainty for providers and patients.

Meanwhile, Medicaid changes in Nebraska are introducing new work rules that could impact coverage for some residents.

What’s next?

For now, California is gathering and submitting the requested Medicaid records by the late-May deadline set by federal officials. State leaders plan to rebut any fraud allegations and seek the timely restoration of funds.

Meanwhile, federal and state investigators will continue probing potential fraud cases. The findings could influence how CMS and states manage Medicaid going forward, and lawmakers may consider these results when shaping oversight rules.
