The Trump Administration Just Withheld $1.3 Billion From California. Here Is What Is Behind the Decision

On Wednesday, Vice President JD Vance stepped before cameras at the White House and announced a federal action against California that few state officials saw arriving at quite this scale. Standing alongside Centers for Medicare and Medicaid Services administrator Dr. Mehmet Oz, Vance delivered a message that landed squarely in the middle of an already tense relationship between the Trump administration and the nation’s most populous state. More than a billion dollars in federal health insurance payments would be withheld, and California was not the only target in the room.

What followed the announcement was a rapid sequence of pushback, legal questions, and sharp exchanges between Washington and Sacramento that illustrated exactly how contested the administration’s anti-fraud campaign has become, and how far the consequences could reach for the roughly 15 million Californians who depend on Medicaid for their healthcare coverage.

Three Announcements, One Afternoon

Wednesday’s press event carried more weight than a single payment deferral. Three separate actions were announced in rapid succession, each with its own set of implications.

First came the $1.3 billion deferral of federal Medicaid payments to California, framed as a consequence of the state’s failure to pursue fraud aggressively enough in the program. Second, the administration announced a nationwide review of every state’s Medicaid Fraud Control Unit, the watchdog agencies that states operate to investigate and prosecute fraud among Medicaid providers. States whose units fail to demonstrate effective enforcement could lose federal support totaling nearly $500 million. Third, CMS announced a six-month moratorium on new enrollment of hospice and home health providers in Medicare, a sector the administration has described as riddled with fraudulent billing.

“We want to protect Medicaid. We want to protect Medicare,” Vance said at the White House event. “But we can’t do that if the states that are administering those programs are allowing those programs to be fleeced by fraudsters.”

Vance insisted the campaign was not politically motivated, even as he and Oz named several Democratic-led states, including California, Minnesota, New York, and Hawaii, as particular concerns. Critics were not persuaded.

Why California Has Been in the Crosshairs

California’s relationship with CMS administrator Oz had already grown adversarial well before Wednesday. Over the preceding months, Oz had filmed videos in the Los Angeles area and made repeated public statements pointing to the state’s hospice industry as a textbook example of what he considers systemic fraud in federal healthcare programs.

His central claim is hard to dismiss on its surface. A third of all hospice providers in the United States are concentrated in Los Angeles, a geographic distribution that Oz and others argue defies any legitimate explanation rooted in patient demand. Oz has said he believes at least half of those providers are operating fraudulently. CMS has already suspended 800 hospices in the region that billed Medicare a combined $1.4 billion last year, and notably few of those suspended providers have since contacted the agency to contest the decision, which Oz described as telling.

Beyond hospice, the administration has raised concerns about California’s broader billing patterns. CMS is scrutinizing providers whose billing volumes are so large that Oz described them as numbers too implausible to reflect legitimate patient care. Home health and personal care spending in California has grown at roughly twice the national average rate, a figure the administration has pointed to repeatedly as evidence that something has gone wrong. CMS is also investigating expenditures connected to undocumented immigrants receiving state-funded coverage, a politically charged element of the scrutiny that California officials have pushed back on separately.

Formal Warnings to State Attorneys General

Wednesday’s announcements were accompanied by formal warning letters sent by the Department of Health and Human Services Office of Inspector General to state attorneys general across the country. California Attorney General Rob Bonta received one, and its language was direct.

“Noncompliance with your MFCU obligations can take your State’s entire Medicaid program out of compliance,” the letter read. “This means your failure to do your job as head of the MFCU has put all of your State’s Medicaid funds in jeopardy.”

Letters went to other states the administration has named in its anti-fraud messaging as well, but California’s received particular attention given the scale of the payment deferral announced the same day. Medicaid Fraud Control Units operate in every state, receiving federal funding to investigate and prosecute fraud among providers. Under the new review, every unit will need to demonstrate that it is working effectively and aggressively, or risk losing that federal support entirely.

California’s Response

Governor Gavin Newsom’s office did not wait long to respond. In a statement posted to social media, his office rejected the administration’s framing directly, arguing that rising billing for home-based and supportive services reflects a deliberate state policy choice rather than fraud. California has spent years working to shift care away from nursing homes and toward in-home support for seniors and people with disabilities, a model that Medicaid policy researchers broadly consider both humane and cost-effective over the long run.

“We hate fraud. But that’s NOT what this is,” the governor’s office wrote. “Vance and Oz are attacking programs that keep seniors and people with disabilities OUT of nursing homes. Pretty sick.”

Newsom has been among the most vocal Democratic governors in pushing back against Trump administration policies across a range of areas, and his office’s response to Wednesday’s announcement fit that pattern. Whether California will pursue legal action, following the path that Minnesota took after its own payment deferral earlier this year, had not been formally announced as of Wednesday.

A Pattern Targeting Democratic States

Wednesday’s California announcement did not arrive in isolation. Since early in the year, the administration’s Medicaid fraud campaign has moved in a consistent direction. President Trump established an anti-fraud task force in March, with Vance leading the group. In February, CMS halted $259 million in Medicaid payments to Minnesota following a high-profile welfare fraud scandal in that state. Minnesota has since challenged the deferral in court, and that legal battle remains unresolved.

Also in February, Oz sent a letter to Maine Governor Janet Mills raising concerns about the state’s Medicaid-funded autism treatment programs and demanding documentation of the state’s fraud prevention and recovery efforts. Mills called it a political attack. Vance was scheduled to visit Maine the day after Wednesday’s announcement, a timing that drew its own attention given that Maine’s Senate race, where Republican Susan Collins is seeking a sixth term, is expected to be one of the most competitive contests in the November midterm elections.

Vance has repeatedly denied that the campaign is driven by political calculations, and the administration has pointed to the scale of the problem it says it is addressing. Oz estimates that fraud, waste, and abuse across federal healthcare programs amount to roughly $100 billion annually, a figure he has cited frequently in public appearances and media interviews.

Does Withholding Funds Actually Fight Fraud

Not everyone is convinced that the administration’s chosen tool matches the stated goal. Andy Schneider, a research professor at Georgetown University who studies Medicaid policy, raised a direct challenge to the logic underpinning the California action.

“It’s not at all clear how deferring $1.3 billion will actually reduce fraud against California’s Medicaid program or help the millions of Californians who rely on Medicaid for access to care and protection against medical debt,” Schneider said.

His question cuts to something the administration has not addressed in detail. Withholding payments does not, on its own, identify fraudulent providers, recover misspent dollars, or prosecute the individuals responsible. It places financial pressure on the state, but the people most immediately affected by a reduction in Medicaid funding are typically the patients who depend on the program for coverage, not the providers or administrators who may have enabled fraud in the first place. California officials have made a version of this argument as well, though the administration has framed any resistance from state governments as evidence of indifference to fraud rather than legitimate policy disagreement.

The Hospice Moratorium and Its Risks

Separate from the California payment deferral, the six-month moratorium on new hospice and home health provider enrollment in Medicare carries its own set of downstream consequences. Oz has been emphatic about the fraud he says he has found in this sector, describing bad actors exploiting vulnerable Medicare patients and stealing from taxpayers in terms that leave little room for nuance.

CMS has already taken significant enforcement action in the hospice space ahead of Wednesday’s moratorium, revoking or deactivating hundreds of providers, increasing oversight in six states, and conducting site visits across the country. The moratorium is intended to stop new fraudulent actors from entering the program while the agency continues removing those it says are already operating improperly.

However, industry groups have raised concerns about what a blanket enrollment freeze means for patients who need hospice care in areas where existing capacity is already limited. National Alliance for Care at Home, a provider advocacy group, warned that the moratorium raises serious access-to-care concerns in areas where patient demand is growing or existing capacity is strained, potentially leading to longer wait times and fewer choices, particularly in rural and underserved communities. Industry groups have said they provided CMS with targeted strategies for stopping bad actors without imposing broad burdens on providers operating in good faith, though it is not clear how much weight those recommendations carried in the final policy decision.

Sacramento Has a Decision to Make

California has not announced legal action as of Wednesday’s announcements, though the Minnesota precedent offers a clear roadmap if state officials choose to contest the deferral in court. All 50 state Medicaid Fraud Control Units now face federal review, with the potential loss of nearly $500 million in support if they cannot demonstrate adequate enforcement activity. CMS has signaled continued scrutiny of home health and personal care billing nationally, with active investigations and site visits already underway in more than half a dozen states.

For California, the immediate question is practical. With $1.3 billion in federal payments deferred and the state’s entire Medicaid funding theoretically at risk if its fraud control unit is found out of compliance, the pressure on Sacramento to respond is substantial. Whether that response comes through legal challenge, accelerated enforcement action, or some combination of both will shape how the next chapter of this standoff unfolds.
