Dr. Mehmet Oz, head of the Centers for Medicare and Medicaid Services, indicates a significant reduction in Affordable Care Act enrollment, citing millions of improper enrollments as the rationale for aggressive audits.
Dr. Mehmet Oz, the Administrator for the Centers for Medicare and Medicaid Services (CMS), has raised concerns about the integrity of the Affordable Care Act (ACA), claiming that the current enrollment figures are inflated by millions of fraudulent or ineligible participants. In a recent interview, Oz suggested that the ACA is burdened by an excess of “improper” enrollments, signaling a shift in federal health policy that may lead to a substantial reduction in the program’s scope.
Oz’s assertion comes at a time when the ACA reports approximately 23 million participants. He argues that this figure is “too high” and should more accurately reflect around 19 million enrollees. This implies that nearly four million individuals currently benefiting from subsidized health care could soon be subject to federal eligibility audits.
“In fact, the fact that we have 23 million makes me think we have too many participants in the ACA,” Oz stated. This stance emerges as open enrollment data for the current year indicates a decline of approximately 1.2 to 1.3 million sign-ups compared to the previous year. This decrease is largely attributed to the expiration of enhanced federal tax credits that had previously shielded low-income families from escalating premiums.
The administration’s rationale for reducing ACA enrollment is supported by a report from the Paragon Health Institute, a conservative think tank. This report estimates that up to five million individuals may be improperly enrolled in subsidized plans for 2024, with potential costs to taxpayers reaching up to $20 billion due to these errors.
Dr. Oz elaborated on various scenarios contributing to this fiscal leakage, including cases where individuals inaccurately report their income—either overstating it to qualify for subsidies or understating it to maximize credits. He also pointed out instances of “duplicate” enrollments, where individuals are simultaneously covered by Medicaid or by plans in multiple states. Additionally, some participants may have access to employer-sponsored insurance but opt for subsidized ACA plans instead, a choice that is prohibited if the employer’s offer is deemed “affordable” under federal guidelines.
“Either their income would not qualify them, they made too much or made too little, or they didn’t file the forms, maybe on purpose,” Oz explained, emphasizing the administration’s concerns.
In response to these issues, the administration has already implemented measures to shorten the open enrollment period and tighten income verification requirements. Critics, however, argue that these so-called “integrity” measures effectively create barriers to entry, suppressing enrollment through bureaucratic obstacles.
While Dr. Oz frames the crackdown as a necessary cleanup of “fraud, waste, and abuse,” nonpartisan health policy experts have expressed skepticism regarding the administration’s claims. They caution that there is a significant difference between “bookkeeping errors” and “criminal fraud,” suggesting that the administration may be conflating the two to advance a broader political agenda.
Cynthia Cox, director of the program on the ACA at KFF, noted that while fraud is indeed a concern in any large-scale government program, the scale described by Dr. Oz lacks substantial evidence. She estimated that while there are likely a few hundred thousand questionable enrollments, the figure of five million is an extreme outlier. “The scale of it may be overstated at times,” she remarked, indicating that most participants are legitimately seeking coverage in a complex system.
Richard Frank, a senior fellow at the Brookings Institution, further criticized the administration’s figures as “implausible.” He argued that what CMS leadership characterizes as fraud often stems from shifting life circumstances, such as mid-year income changes or relocations between states. He warned that labeling these situations as fraudulent could disenfranchise eligible Americans who may not have the necessary documentation to prove their status on short notice.
The push to reduce ACA enrollment is occurring alongside a broader strategy by the administration. Recently, Vice President JD Vance and Dr. Oz withheld $259 million in Medicaid funding from Minnesota, citing widespread fraud. This action was condemned by Democratic lawmakers as a punitive measure against a blue state, but for the administration, it serves as a model for a national strategy.
Simultaneously, the administration is attempting to attract a different demographic: young, healthy, and currently uninsured Americans. This strategy involves promoting high-deductible, low-premium plans. The rationale is clear: by bringing “young invincibles” into the risk pool, the overall cost of the marketplace could stabilize. However, this creates a paradox where the administration is aggressively pushing some individuals out through audits while simultaneously inviting others in with the promise of cheaper, albeit less comprehensive, coverage.
For millions of self-employed Americans and small business owners who rely on the ACA, the coming months are likely to be marked by increased scrutiny and rising costs. With double-digit premium increases already affecting many markets following the lapse of congressional tax credits, the prospect of aggressive federal audits adds another layer of uncertainty to a system already under significant financial strain.
As the administration moves forward with its plans, the implications for the ACA and its enrollees remain to be seen, raising questions about the future of health care coverage in the United States.
