Federal regulators are ending Affordable Care Act (ACA) subsidies for 189,000 marketplace enrollees flagged as duplicates, enrolled in other government coverage or deceased.
The administration says the step will prevent $738 million in payments this year, according to Reuters. Robert F. Kennedy Jr., secretary of the U.S. Department of Health and Human Services (HHS) in Washington, D.C., announced the action on October 14, 2026.
The Centers for Medicare & Medicaid Services (CMS) said it identified 189,000 people with subsidized Federal Marketplace coverage who also held Medicare, Medicaid or Children’s Health Insurance Program coverage, or who were deceased, according to an HHS press release dated October 14, 2026. The release did not break the total down by category.
HHS said duplicate-enrollment enforcement resumed in 2025 and ended subsidies for approximately 551,000 enrollees already covered by Medicaid. It said the checks could save taxpayers approximately $1.5 billion annually.
CMS Administrator Mehmet Oz said in the release that the agency has saved nearly $6 billion. He also criticized the prior administration for pausing duplicate-coverage reviews for four years. Kennedy said that “taxpayers should not foot the bill for duplicate coverage,” or for subsidies tied to people who have died.
HHS said people whose records show overlapping coverage are contacted and given 30 days to dispute the finding or cancel the duplicate coverage. If they do neither, CMS ends their subsidies. For people federal records list as deceased, CMS contacts the individual or their estate and allows 30 days to dispute the record. Otherwise it cancels the subsidy and the plan.
The action lands in a shrinking market. KFF Health News reported that ACA plan enrollment fell by nearly 3 million this year to about 19.2 million. It attributed the drop to steep premium increases and Congress’s decision not to extend enhanced premium subsidies.
The administration attributes part of that decline to improper enrollment. According to KFF Health News, an administration report suggests that fraudulent agents and brokers moved very low-income enrollees into zero-premium plans to keep earning commissions.
Matthew Fiedler, a senior fellow at the Brookings Institution in Washington, D.C., disputed the broader claim. He told KFF Health News that the idea that improper enrollees explain the entire decline since 2025 “is not remotely credible.”
Benefits brokers whose employer clients have workers or dependents buying marketplace coverage may now field questions about the 30-day notices. Brokers who help individuals enroll will also be watching how regulators characterize agent and broker conduct.
