Medicare AI Claims Pilot Drives High Denial Rates and Delays, Lawsuit States

Industry Pulse News Desk · 2026-09-15

A federal lawsuit reveals that an artificial intelligence pilot program used for Medicare claims resulted in widespread care denials and vendor readiness warnings.

A pilot program using artificial intelligence to process and approve coverage for Medicare beneficiaries has resulted in elevated claim denial rates and significant decision delays, according to documents cited in a federal lawsuit seeking details about the initiative.

The legal action highlights growing challenges with the automated system, which was deployed to evaluate care requests across federal health programs. Internal records referenced in the suit indicate that even a technology vendor contracted for the project warned administrators about a lack of readiness prior to the program's launch.

Despite those initial warnings, the automated claims platform was integrated into the authorization process. The system subsequently generated rejections at rates far exceeding historical averages under standard administrative review, while delaying medical care approvals for affected patients.

Advocates behind the lawsuit are seeking the full release of operational records, algorithm performance metrics, and evaluation standards. They contend that the use of undisclosed algorithms to make coverage determinations undermines transparency and compromises beneficiary access to necessary medical treatments.

The litigation comes amid heightened scrutiny from lawmakers and consumer protection groups regarding the reliance on automated decision-making tools in public healthcare administration. Federal agencies managing the Medicare program have not yet publicly responded to the specific allegations raised in the court filing.
