The Centers for Medicare & Medicaid Services announced October 14 that it identified approximately 189,000 federal health-insurance marketplace enrollment records associated with people who also had Medicare, Medicaid or Children’s Health Insurance Program coverage, or who were recorded as deceased.
CMS said it took steps to end federal premium subsidies associated with those records and projects potential savings of approximately $1.5 billion over the next year. That figure is an agency projection, not a verified final savings total.
Under the review process described by CMS, people flagged for potentially duplicative coverage are contacted and generally given 30 days to dispute the finding. CMS also provides appeal procedures and says subsidy eligibility may be restored when a record is corrected or other coverage is ending. The agency says records showing a person as deceased also can be disputed.
Administrative data matches are not by themselves findings of fraud. The 189,000 figure combines different kinds of enrollment discrepancies and records, and the agency did not say that every individual intentionally made a false claim.
The announcement raises questions about how many cases reflect data errors, how promptly impacted households receive notices, and how many adjustments are reversed on appeal. SNN will update this report as verified outcomes become available.
