The Trump administration on Wednesday imposed a nationwide six-month moratorium on all new Medicare enrollments by hospice and home health care providers, the most aggressive step yet in a broadening crackdown on fraud in federal health programs. The freeze blocks new providers from entering Medicare while the Centers for Medicare and Medicaid Services ramps up investigations into those already billing the system.
CMS Administrator Dr. Mehmet Oz framed the action as a necessary shield for taxpayers and vulnerable patients. Existing providers will continue to operate as usual during the pause.
The enrollment freeze landed alongside a separate warning from the Department of Health and Human Services' internal watchdog, which sent letters to state attorneys general telling them to vigorously investigate possible Medicaid fraud or risk losing federal money. Together, the moves mark a significant escalation, one that targets both the supply side of health care fraud and the states that have, in the administration's view, failed to police it.
The moratorium applies to all new Medicare enrollments by providers of hospice and home care nationwide. No new entities in those categories can enter the Medicare system for six months. CMS said it will "intensify targeted investigations, deploy advanced data analytics, and accelerate the removal" of providers already suspected of fraudulent billing.
In a statement reported by Newsmax, Oz did not mince words:
"We've seen systemic and deeply troubling fraud in the hospice and home health space, with bad actors exploiting some of our most vulnerable Medicare patients and stealing money from the American taxpayer. Today we're shutting the door on fraud, preventing new bad actors from entering Medicare while we aggressively identify, investigate, and remove those already exploiting them."
The hospice and home health moratorium is not the only enrollment freeze CMS has imposed in recent months. The agency also issued a separate six-month moratorium on suppliers of durable medical equipment, prosthetics, orthotics, and certain other supplies in Medicare.
Vice President JD Vance, who leads the White House Fraud Task Force created by President Trump on March 16, has been the public face of the broader anti-fraud campaign. Vance has promoted the task force's work during campaign stops for Republican candidates and was expected to focus on the effort Thursday in Maine, where closely watched primary races are set for June 9.
The numbers behind the crackdown are staggering. CMS has already suspended payments to hundreds of hospice and home care agencies in Los Angeles over alleged fraud. The administration halted some $243 million in Medicaid payments to Minnesota over fraud concerns. And at least five states have been approached with investigations into potential health care fraud.
The Minnesota fraud controversy has generated political fallout of its own, with state-level accountability efforts intensifying as federal investigators dig deeper.
Oz told reporters in a separate statement that the administration had already stopped $1.5 billion in billing and believes the broader crackdown will address billions more in durable medical equipment fraud alone. Just The News reported that Oz described the moratorium as an "unfortunate necessity," saying: "We already stopped a billion and a half dollars of billing, but we need more time to shut down these bad guys."
Last month, Oz announced CMS would require all 50 states to share how they planned to revalidate some of their Medicaid providers, a step that puts every state on notice, not just the ones already under investigation.
The HHS watchdog's letters to state attorneys general carry a blunt message: cooperate or face consequences. The administration has made clear it views state-level inaction on Medicaid fraud as part of the problem.
Not every state sees it that way. Maine's Democratic Governor Janet Mills characterized an earlier request from Oz for corrective action on alleged fraud in her state's government health programs as a "political attack." The administration has shown no sign of backing down.
The broader push to crack down on fraud in states like Minnesota has drawn sharp political lines, with the administration targeting what it describes as systemic failures in oversight.
The tension between federal enforcement and state resistance is likely to grow. Millions of Medicaid enrollees are expected to lose their health coverage because of new work requirements, and critics have tried to blur the line between anti-fraud enforcement and benefit cuts. But the administration's position is straightforward: rooting out fraudulent providers preserves funding and resources for people who actually need them.
The moratorium is not without precedent. Tricia Neumann, senior vice president and executive director for the program on Medicare policy at KFF, a health care research nonprofit, noted that the Clinton administration also imposed a temporary moratorium on home health agencies.
"A brief moratorium gives the administration time to crack down on true fraud and prevent new fraudulent entities from popping up."
That historical parallel matters. If a Democratic administration found the same tool necessary decades ago, the current freeze can hardly be dismissed as partisan overreach. The difference now is scale. The Trump administration is pairing the enrollment freeze with aggressive data analytics, accelerated provider removals, payment suspensions in specific markets like Los Angeles, and direct pressure on state governments.
The anti-fraud effort also fits within a broader DOJ fraud crackdown that has identified up to $1 trillion in taxpayer programs at risk of waste, fraud, and abuse.
Even as the administration pushes forward, questions linger about whether its own bureaucracy is fully on board. A Washington Examiner review found roughly four dozen senior CMS staffers in influential roles who were first elevated under Democratic administrations, previously held Democratic political roles, or worked at left-of-center advocacy groups. Key CMS oversight and enrollment divisions involved in provider enrollment and anti-fraud functions are led by officials who are holdovers from the Obama and Biden administrations.
Sarah Lee, communications director at the Capital Research Center, told the Washington Examiner that the stakes are real: "Whoever is working at CMS should be serious about getting a handle on the enrollment numbers so that any potential fraud can be investigated. Otherwise, it's another slap in the face to the American taxpayer."
The presence of holdover staff in the very divisions responsible for enrollment and fraud detection raises an obvious question: can the administration's anti-fraud directives be executed faithfully by a workforce that may not share its priorities?
Healthcare industry leaders have urged caution, warning that aggressive enforcement measures like enrollment moratoriums may disrupt legitimate providers and patient access. That concern is worth taking seriously, no one benefits if honest home health agencies cannot serve elderly patients because the enrollment window is shut.
But the administration's counter-argument is equally serious. Fraudulent providers don't just steal taxpayer dollars. They crowd out legitimate caregivers, inflate costs, and degrade the quality of care for the most vulnerable Americans. A six-month pause to clean house is a modest price if it prevents billions more from draining out of the system.
The administration has signaled it is "taking down thousands" of fraudulent actors and has no plans to slow down.
The administration's record on this front is not spotless. In April, CMS acknowledged to The Associated Press that it made a significant error in figures it used to help justify a fraud probe in New York. The details of the error were not specified, but the admission hands critics an easy talking point.
That stumble, however, does not erase the underlying problem. The fraud is real. The dollar amounts are enormous. And the patients being exploited, elderly Americans receiving hospice and home health care, are among the least able to advocate for themselves.
The moratorium runs for six months. During that window, CMS has committed to deploying advanced data analytics and accelerating the removal of suspect providers. The letters to state attorneys general set up a parallel track of pressure on state governments. And the broader Fraud Task Force, led by Vance, shows every sign of expanding its reach as the administration heads toward the November elections.
Several open questions remain. Which states beyond Minnesota received letters from the HHS watchdog? What specific legal authority did CMS invoke for the moratorium? And will the agency's holdover staff execute the crackdown with the urgency the administration demands?
The answers will determine whether this moratorium is remembered as a turning point in federal health care enforcement, or as a bold promise that the bureaucracy quietly smothered.
Taxpayers have been footing the bill for health care fraud for decades. They deserve an administration willing to shut the door, even temporarily, and clean house. The real question is whether Washington's permanent class will let it happen.
