U.S. cancels about 315,000 ACA Marketplace enrollments covering more than 760,000 people

In a September 22 fact sheet, CMS said it canceled approximately 315,000 Marketplace enrollments covering more than 760,000 people on August 31. The agency said the finding resulted from a review and investigation with health insurers under its existing process for unauthorized enrollments. That is the government's official determination; individual circumstances may differ.

CMS expects the cancellations to result in the return of roughly $2.2 billion in advance payments of the premium tax credit. The agency said it will keep working with insurers to identify and investigate other potentially unauthorized enrollments, cancel confirmed cases and recoup associated past subsidy payments.

CMS also described stronger enforcement against agents and brokers who help consumers enroll. Since January 2026, it has sent termination notices to more than 200 non-compliant agents and brokers. This summer it issued 569 notices of intent to terminate Marketplace agreements, including for 2026 applications missing applicant information such as Social Security numbers. Of the first 100 cases whose response period had ended, 66 had received termination notices when the fact sheet was published.

Reuters reported that some cancellations involved unverified citizenship or immigration documentation and suspected improper enrollment. An insurance-broker industry group criticized a broader freeze on new broker registrations as potentially harming legitimate professionals. N Globe treats the cancellation totals, number of people and CMS enforcement actions as confirmed, but does not turn the government's case-by-case fraud assessments into criminal allegations against everyone affected.

People affected should use HealthCare.gov or an official state Marketplace to review their current coverage, notices and appeal options, and retain official records.
