Mehmet Oz, who runs the Centers for Medicare and Medicaid Services, stood with him. The savings number is an administration estimate. The Congressional Budget Office has not scored it.

CMS had already acted. Rulemaking documents posted Tuesday in the Federal Register say the agency canceled 315,000 marketplace policies on Aug. 31, covering roughly 760,000 people, which the rule describes as unauthorized enrollments submitted through agents and brokers. Vance's 750,000 and the 760,000 covered lives are the same purge, counted two ways.

Officials also plan another pass at about 419,000 current enrollees, checking legal residency first and income second. "We are actually making sure that people receiving Obamacare subsidies are actually entitled to receive them," Vance said. "Amazingly we weren't doing that before."

Brokers are next. CMS sent notices of intent to terminate to 569 agents and brokers who filed statistically implausible rates of 2026 applications without identifying information, such as a Social Security number. A separate interim-final rule freezes new agent and broker registrations until Feb. 1, 2027, before the usual comment period runs. Administration officials said 40 brokers accounted for about 50,000 suspect enrollments and $45 million in subsidies. The National Association of Benefits and Insurance Professionals said a blanket freeze punishes licensed agents who did nothing wrong and will leave consumers with fewer people to call during open enrollment.

Centene fell as much as 3.9 percent on the first headlines. Molina dropped as much as 3.5 percent, Elevance 1.9 percent, UnitedHealth 1.4 percent. Those firms write a large share of exchange business. Federal premium tax credits are paid to the insurer, not the enrollee.

How The Administration Is Using The Word

Part of the case is conventional fraud. Brokers collect commissions from insurers. After Congress fattened the premium tax credits, a lot of low-income plans carried a $0 net premium, so a policy could be opened without the customer ever seeing a bill. CMS recorded roughly 275,000 complaints in an eight-month stretch of 2024 from people who said they had been enrolled or switched without consent. In February, a brokerage president and a marketing-company CEO were sentenced to 20 years each for a scheme that sought more than $233 million in subsidies. HHS has separately said more than a million marketplace enrollments listed no Social Security number.

The rest is a verification net the last administration loosened and this one is pulling tight: income attestations, immigration paperwork, employer coverage, automatic re-enrollment onto free plans.

The Government Accountability Office has found the same weak controls and has not signed off on the claim that millions of current enrollees are fake. GAO flagged at least 160,000 federal-marketplace applications in plan year 2024 for likely unauthorized changes, about 1.5 percent of the relevant pool. It found about 68,000 Social Security numbers used for more than a year of subsidized coverage in 2024; one number appeared on 125 policies. About $94 million in subsidies went out on numbers that matched the death file. Undercover testers got fictitious applicants approved at very high rates, and most of the 2025 fakes were still drawing subsidies months later. GAO has described that work as a set of risk indicators, not a census.
