More than one million people enrolled in Obamacare health plans lack Social Security numbers, a figure that Health and Human Services Secretary Robert F. Kennedy Jr. called "a glaring warning sign for fraud" in a video announcement alongside Centers for Medicare and Medicaid Services Administrator Dr. Mehmet Oz.
The two officials, speaking Saturday from Washington, laid out what they described as a system riddled with bogus enrollments, rogue insurance agents, and phantom identities, all bankrolled by taxpayer-subsidized premiums. Kennedy placed the blame squarely on the prior administration.
The core claim is striking on its own terms. Out of an estimated 19.2 million Americans currently enrolled in Obamacare exchange plans, the latest figure from an HHS enrollment report, more than one million have no Social Security number on file. Kennedy and Oz framed that gap not as a clerical curiosity but as evidence of systematic fraud that flourished under weakened oversight.
Kennedy did not hold back about who he believes let the problem fester. As the New York Post reported, the HHS Secretary directly accused the Biden administration of stripping away the checks that were supposed to keep the marketplace honest.
"The Obamacare marketplace is plagued by fraud in large part because the Biden administration dismantled basic program integrity guardrails, while partisan lawfare blocked common sense efforts to protect taxpayers."
That charge raises an obvious question: what specific guardrails were removed, and when? Kennedy did not detail the particular rules or enforcement mechanisms he was referencing. But the timeline tells its own story. Obamacare enrollment swelled to roughly 23.4 million in 2025, according to data from the Kaiser Family Foundation. Enhanced subsidies put in place under the Biden administration expired at the end of last year. Now, with enrollment settling at 19.2 million, the administration says it is finding fraud baked into the rolls.
The pattern Kennedy described is not subtle. People who may not even exist are drawing taxpayer-funded insurance coverage. And the question he posed cuts to the bone.
"Why are we paying people we don't know if they actually exist?"
It is a fair question. In any other federal program, a million enrollees without basic identity verification would prompt immediate congressional hearings. That it apparently persisted for years inside the Affordable Care Act's marketplace, the signature domestic achievement of the Obama presidency, a program that faced tough public scrutiny from the start, demands a full accounting.
Dr. Oz offered a more granular picture of the alleged fraud scheme. He described a network of bad actors gaming the enrollment system from the outside, and profiting from it.
Oz stated that "rogue agents and other bad actors" have been enrolling "unsuspecting Americans in health plans they never signed up for," and using fake identities to collect fees from insurance companies for "selling plans they never legitimately sold." In other words, the scam works in two directions: real people get signed up for coverage they never requested, and fictitious people get enrolled so agents can pocket commissions.
The CMS administrator zeroed in on the Social Security number gap as a telltale marker.
"Some of these agents refuse to follow basic rules, like providing their clients' social security numbers. That, my friends, is a huge red flag."
He followed with a direct warning aimed at those exploiting the system.
"If you're a fraudster, here's our advice to you: do not walk away from us, run, because we are going to find you."
The rhetoric is forceful. But the article itself acknowledged a significant unknown: it is not clear how widespread the phenomenon of rogue-agent enrollment actually is. Kennedy and Oz said they have already eliminated "thousands of fraudulent enrollments," though the precise number was not disclosed. Nor did they specify how many of the million-plus enrollees without Social Security numbers are suspected of outright fraud versus having some other explanation for the missing data.
The raw figure, more than one million, is large enough to matter. It represents roughly five percent of total current Obamacare enrollment. But the gap between "lacks a Social Security number" and "confirmed fraud" has not been publicly bridged by HHS or CMS. Some enrollees without SSNs could be lawful residents using alternative documentation. Others could be victims of the rogue-agent schemes Oz described, their identities hijacked or fabricated without their knowledge.
What is not in dispute is that the administration views the number as a serious integrity problem. Kennedy stated that he and Oz are "working with insurers to cancel every policy that should never have been issued and recover every taxpayer dollar that was fraudulently paid out." That language, every policy, every dollar, suggests the administration intends to treat the entire pool of SSN-less enrollments as presumptively suspect until proven otherwise.
Just The News reported that both Kennedy and Oz said they are dedicating more resources than the Biden administration did to rooting out healthcare fraud and protecting American taxpayers. The scale of the cleanup, if it proceeds as described, would be one of the largest enrollment audits in the ACA's history.
The financial stakes are not trivial. Every fraudulent enrollment represents a premium subsidy drawn from federal coffers, which means from taxpayers. Multiply that across a million enrollees, factor in years of coverage, and the potential waste runs into the billions. Yet no total dollar figure has been released.
The broader context matters. The Affordable Care Act was designed to maximize enrollment. The Biden administration leaned hard into that mission, expanding subsidies and loosening eligibility checks to push the rolls higher. By 2025, enrollment hit a record 23.4 million. The political incentive was always to report bigger numbers, more people covered, more success to claim.
But enrollment numbers are only as meaningful as the people behind them. If a significant share of enrollees are phantoms, duplicates, or victims of identity fraud, then the celebrated coverage gains were partly illusory, and the cost to taxpayers was very real. The rising price of health insurance premiums, which now exceed the average mortgage payment, makes the question of who is actually benefiting from these plans all the more urgent.
Kennedy's reference to "partisan lawfare" blocking fraud-prevention efforts adds another layer. He appears to be alluding to legal challenges that prevented earlier attempts to tighten enrollment verification, though he did not name specific cases or rulings. If courts or advocacy groups actively blocked common-sense identity checks, that is a story that deserves its own investigation.
The political dynamics around Obamacare have always made honest oversight difficult. Democrats treated enrollment numbers as proof the law was working. Any effort to verify those numbers risked being cast as an attack on healthcare access. That framing effectively shielded the program from the kind of routine integrity checks that apply to food stamps, housing vouchers, and virtually every other federal benefit.
The result, if Kennedy and Oz's findings hold up, is a program where the front door was wide open and nobody was checking IDs.
For all the force of the announcement, significant gaps remain. The administration has not disclosed the total taxpayer dollars paid out on behalf of enrollees without Social Security numbers. It has not specified what legal or regulatory actions, if any, have been taken against identified rogue agents. And it has not explained precisely which Biden-era policy changes created the vulnerabilities Kennedy described.
Those details matter. A fraud allegation of this scale demands documentation, not just rhetoric. Kennedy and Oz have made a strong opening case. Now they need to show the receipts, the specific rule changes, the dollar figures, the enforcement actions, and the referrals to law enforcement.
The healthcare policy fights playing out in Congress add urgency. Lawmakers in both parties face difficult choices about ACA subsidies and program structure heading into 2026. If the marketplace is as compromised as Kennedy and Oz suggest, those debates cannot proceed honestly without a full fraud audit on the table.
Meanwhile, the broader question of institutional accountability continues to divide the country along familiar lines. Courts and officials alike face pressure to confront uncomfortable truths about programs that powerful constituencies would rather leave unexamined.
Kennedy and Oz have declared a zero-tolerance policy for Obamacare fraud. They have put a number on the problem, more than one million enrollees with no Social Security numbers, and they have promised to cancel bogus policies and claw back misspent funds. The question now is whether the bureaucracy they inherited will cooperate, and whether the political establishment that inflated those enrollment rolls will allow a genuine reckoning.
When a government program counts a million people it cannot even identify, the failure is not a glitch. It is a feature of a system that valued sign-ups over accountability, and stuck taxpayers with the tab.
