The Trump administration credits its fraud control efforts for the disappearance of millions of people from Obamacare rolls rather than a sharp rise in premiums — a claim disputed by policy experts that glosses over the reality that many more Americans now find themselves without health insurance.Enrollment in Affordable Care Act plans fell by nearly 3 million this year to about 19.2 million, following steep premium increases by insurers and the Republican-led Congress' unwillingness to extend more generous premium subsidies. On average, ACA customers pay $178 a month in premium payments this year, a 58% increase from 2025, according to KFF, while their deductibles — the amount consumers must pay annually before insurers pick up their share — have climbed 37% to nearly $3,800 a year."These are real people who are now forced to make impossible choices," said Annalyse Keller, a spokesperson for Keep Americans Covered, a large coalition of lobby organizations for the healthcare industry, including insurers and patient advocacy groups.But a Department of Health and Human Services report released in June, written mostly by President Trump's political appointees and allies, asserts that 5.6 million people were fraudulently enrolled in ACA plans in 2025, and that the Trump administration removed 2.9 million of them — the same number as the 2026 drop in enrollment.There's little dispute that the ACA suffers from some fraud, as do most government programs. The administration said it has taken actions to tighten the enrollment process to thwart brokers who fraudulently enroll people without their knowledge.For example, the administration in August 2025 halted a Biden-era initiative that allowed low-income people to sign up for coverage year-round. Regulators also have removed 1.5 million people since 2025 for reasons such as not meeting a requirement to file their taxes over two years or being concurrently enrolled in another health program, such as Medicaid, which is not allowed.But health policy experts say that the administration is overstating the extent of ACA fraud and that the HHS report relies on debatable assumptions, such as that all sign-ups under the year-round enrollment program for low-income people were potentially fraudulent. ACA enrollment fell off a cliff because of escalating prices for insurance plans, policy analysts say, which the administration's done nothing to stem.
