WISeR AI program reportedly denied or delayed Medicare care for seniors in several states
Preliminary Why: Publisher not yet named · subject to change
Status: no action reported
No source states: loss or records, developer and model, agent tool, could do, deployer.
Severity moderate: test: bounded scope stated (select clinics in six states); no third party count or unbounded scope stated
A federal pilot program called WISeR uses artificial intelligence models to help decide whether Medicare requests for treatments and services are approved. The models are used at select clinics in six states: Texas, New Jersey, Oklahoma, Ohio, Washington and Arizona. A lawsuit by the Electronic Frontier Foundation alleges the models were denying care at disproportionately high rates. In Texas, the models approved care for 62% of patients, while humans approved 84%. The suit also reports that contracted vendors have financial incentives to deny prior approval. Physicians reported high denial rates and delays in approvals. The lawsuit sought records on whether the systems were tested for accuracy and bias. Whether the government audited or monitored performance is unclear. CMS plans a six-month performance report, but no date has been given.

The source is one press article citing a lawsuit; no primary document was provided. Not stated: incident dates beyond the January 2026 launch, the lawsuit filing date, and the date of disclosure (the article date 2026-10-26 was not used as disclosure date). No remediation is reported; the CMS report is planned, not a change. The 62% and 84% figures are the lawsuit's as reported by the press, not verified.
