Dr. Oz Claims Obamacare Enrollment Numbers Are 'Excessive'
Dr. Mehmet Oz, a prominent figure in health policy, has voiced his concerns regarding the current enrollment figures for the Affordable Care Act (ACA), suggesting they may be inflated. Despite a notable decline in sign-ups this year due to soaring premiums, Oz asserts that the total number of enrollees remains excessively high.
According to the latest statistics from the Centers for Medicare and Medicaid Services, approximately 23 million individuals registered for ACA coverage during the recent open enrollment period, which concluded in January. This figure represents a decrease of about 1.2 to 1.3 million compared to the previous year. The ACA typically attracts those who are self-employed or lack employer-sponsored insurance.
In a recent phone interview, Oz expressed skepticism about the legitimacy of some enrollments, predicting a further drop to around 19 million. “The fact that we have 23 million makes me think we have too many participants in the ACA,” he stated bluntly. “It’s too high of a number.”
Oz elaborated on his concerns, suggesting that fraudulent enrollments and administrative errors may contribute to the inflated figures. He pointed out that some individuals may have been mistakenly enrolled, received duplicate coverage, or obtained tax credits for which they were ineligible. Furthermore, he noted that many could qualify for Medicaid or employer-based insurance but opt for ACA plans instead.
Last year, the administration estimated that between 4 million and 5 million individuals were improperly enrolled in subsidized ACA coverage for 2024, potentially costing taxpayers up to $20 billion. This claim was supported by research from the Paragon Health Institute, a conservative think tank advocating for reforms in the ACA.
“Either their income would not qualify them, they made too much or too little, or they didn’t file the forms, maybe on purpose,” Oz explained. “These are major concerns for us.”
The mantra of “fraud, waste and abuse” has been a recurring theme for Oz, who has linked certain communities in California and Minnesota to health care fraud. Recently, Vice President JD Vance, alongside Oz, announced a decision to withhold $259 million in Medicaid funding for Minnesota due to alleged fraud—an assertion that has drawn criticism from Democratic leaders as politically motivated.
Health policy experts acknowledge that while fraud exists within the ACA marketplace, its extent may not align with the administration's claims. Cynthia Cox, director of the ACA program at a nonpartisan health policy research group, stated that while fraudulent enrollments are a concern, estimates suggest only a few hundred thousand cases exist rather than millions.
Richard Frank from the Brookings Institution echoed this sentiment, deeming it “implausible” that 4 million to 5 million individuals are wrongly enrolled in the ACA. “The number is not zero,” he clarified. “But what people are calling fraud are very often just bookkeeping errors.”
The decline in ACA enrollment this year follows Congress's failure to extend enhanced tax credits that previously kept premiums manageable, resulting in significant premium hikes for many Americans. Experts fear these increased costs may lead more individuals to drop their coverage or switch to cheaper plans with higher deductibles—a trend already observed by state officials.
Despite Oz's assertions regarding ineligible enrollees, the administration is actively seeking ways to expand participation in the ACA. In February, proposed changes aimed at attracting younger and healthier individuals into the marketplace were introduced. This initiative includes raising the age limit for catastrophic health plans.
Catastrophic plans represent the lowest tier of ACA coverage, typically available to those under 30 and characterized by low premiums but high deductibles. According to KFF data, the average annual deductible for such a plan was $10,600 for individuals and $21,200 for families in 2026.
Oz expressed uncertainty about whether the Centers for Medicare and Medicaid Services had disclosed potential deductible limits under the new proposal but contested an estimate suggesting they could reach $31,000 for families. “How do I get people off the sidelines to participate in the ACA who otherwise wouldn’t?” he questioned.
Cox raised concerns that while the proposal might attract younger individuals, it could also draw older adults and those with pre-existing conditions who require more comprehensive coverage. She emphasized that health care literacy remains low in the U.S., leading some individuals to misunderstand their insurance options.
Frank reiterated this point, noting that consumers often struggle with complex insurance policies. “Even high-deductible plans are really complicated,” he remarked.
Addressing these issues, Oz highlighted the importance of transparency in health care decisions. He referenced President Trump’s “Great Healthcare Plan,” which advocates for insurance companies to provide clear summaries of their benefits in plain language.
Oz concluded by asserting that individuals are capable of making informed health care choices. “Most folks who are older and have comorbidities are not going to want catastrophic plans for reasons that are self-evident,” he stated.
