The Centers for Medicare & Medicaid Services says it canceled approximately 315,000 Affordable Care Act Marketplace policies covering more than 760,000 people after finding unverified eligibility information and signs of unauthorized enrollment.

The cancellations, carried out Aug. 31 and disclosed Tuesday, mark one of the largest single administrative removals from the federal health-insurance exchanges. Vice President JD Vance said the action would recover about $2.2 billion in advance premium tax-credit payments. That savings figure is an administration estimate, not a completed audit.

CMS said the affected policies involved agent or broker assistance, lacked verified citizenship or immigration documentation, and showed no claims or successful consumer contact. The agency’s rule also imposes a temporary moratorium on newly registering agents and brokers in the federally facilitated exchanges through Feb. 1, 2027.

The Associated Press and Reuters independently reported the scope of the cancellations and the administration’s rationale. Both also documented questions from health-policy specialists and insurance brokers about whether the screening process could remove eligible consumers along with fraudulent or unauthorized accounts.

Why CMS says it acted

The federal rule describes a pattern of applications missing Social Security numbers or immigration document numbers, unresolved income or citizenship mismatches, and other compliance indicators. CMS said newly registered brokers represented about 11% of brokers with active 2026 enrollments but roughly 30% of the 569 brokers who received notices of intent to terminate their exchange agreements in July and August.

According to CMS, brokers who first registered for the 2026 plan year were about three times more likely than previously registered brokers to show potential noncompliance. Their applications had higher rates of unresolved income-verification issues, missing Social Security numbers and unresolved citizenship or immigration-status checks.

Those are risk indicators rather than proof that every policy associated with them was fraudulent. CMS paired the data with additional criteria for the canceled accounts: issuers could not identify claims, officials could not establish consumer contact and eligibility documentation remained unverified. The administration said some records may have involved people enrolled without their knowledge, while others may have represented people who did not exist or failed eligibility rules.

A June HHS report estimated that 2.6 million improper or “phantom” enrollments remained in the exchanges, including more than 1 million without a Social Security number. The report cited earlier CMS estimates that as many as 4.4 million 2024 enrollments may have been improper. Those estimates rely on administrative indicators and should not be treated as findings that each named enrollee committed fraud.

What the broker freeze changes

The moratorium affects agents and brokers who lacked active 2026 exchange agreements and otherwise would have registered for the 2027 plan year. It does not suspend all brokers, and it does not apply to brokers working through state-based exchanges. The federal rule also permits registration after a favorable reconsideration decision for a broker whose agreement had been terminated.

CMS estimated that, without the freeze, nearly 20,000 agents and brokers would have registered during the covered period, with about 6,956 generating active enrollments. The agency projected that those brokers could forgo $71 million to $98 million in commissions, though it expects much of that business to move to already registered brokers.

The National Association of Benefits and Insurance Professionals opposed the blanket approach, arguing through Reuters that targeted enforcement would better protect legitimate brokers and consumers. Analysts also warned that reducing the broker pool could make enrollment harder for people who rely on professional assistance, particularly as the Marketplace is already contracting after enhanced subsidies expired.

The unresolved consumer question

The administration said an additional 419,000 to 450,000 enrollments will receive further verification. That review will test whether enrollees meet residency, income and other program requirements. CMS also plans stronger identity proofing for brokers and requirements that broker-assisted applications contain verifiable identification information.

For consumers, the central unresolved issue is error correction. The government has not publicly provided a detailed breakdown showing how many canceled policies involved nonexistent people, unauthorized enrollment or real applicants who could still establish eligibility. Policy experts told the AP that canceling clearly fraudulent coverage is appropriate but questioned whether the administration’s process could reliably separate those cases from eligible households.

The scale is significant but smaller than the full Marketplace population. About 19.2 million people were actively enrolled in ACA Marketplace plans early this year, according to HHS figures cited by the AP. The 760,000 people tied to canceled policies represent roughly 4% of that total.

CMS says the intervention protects consumers and federal funds from unauthorized enrollments, surprise plan changes and improper subsidies. Critics agree fraud warrants enforcement but want more transparency about the cancellation methodology and a clear route for legitimate enrollees to restore coverage. Whether those safeguards work will determine if the crackdown primarily removes phantom accounts or also leaves eligible families without insurance.
