The Story
WISeR’s rollout delayed care and produced troubling denials; the full scale of AI-caused harm still needs evidence.
WISeR is best understood as a rushed prior-authorization pilot whose technical failures, weak communication, and vendor-management problems disrupted care. The records support real delays and inappropriate denials, but they do not establish that every denial came from an AI model or provide a complete measure of patient injury. Clinician review and appeals remain central to judging individual cases.
- EvidenceReleased CMS records and reporting document high denial rates, long waits, technical failures, and patient complaints.
- AccountabilityCMS must show how vendors were tested, monitored, corrected, and held responsible for late or inaccurate decisions.
- CMS records describe widespread delays, denials, operational chaos, and reports of patient harm during WISeR’s rollout.
- Provider and patient accounts describe extra appointments, prolonged waits, pain, and difficulty obtaining answers about requested care.
- The available reporting does not establish that every adverse decision was made by AI rather than by rules, vendor processes, or the wider prior-authorization system.
Deeper Insight
WISeR paid vendors for rejected care, so Medicare made denial profitable and delay nearly free.
A Medicare patient waits while WISeR, Medicare’s AI prior-authorization program, routes care decisions through private vendors. Records show delays, technical failures, inaccurate denials, and weak communication. The contract made rejection profitable, paying vendors up to a quarter of a service’s typical Medicare payment while slow answers faced no comparable penalty.
- What it could changeCongress could treat automated Medicare decisions as regulated exercises of public power, requiring transparent rules, audit trails, meaningful appeals, and penalties for harmful delay.
- How it touches todayClinicians and patients can demand the record behind a denial, while CMS can tie vendor pay to timely, accurate approvals instead of rewarding rejection.
- Our futureIf contracts keep rewarding refusal, more public decisions could become private software pipelines. The question is whether automation serves patients, or merely makes rationing harder to see.
- WISeR vendors were reportedly paid up to a quarter of a service’s typical Medicare payment when a rejection stood, while approvals generated no comparable payment.
- One vendor reportedly rejected more than half of its decisions in the first quarter, while speed was not included in the payment-adjusting score through September.
- EFF’s records show private companies were given consequential Medicare decision-making responsibilities amid questions about testing, safeguards, transparency, and corrective action.

New Records Obtained by EFF Expose More Problems with Medicare’s AI Experiment
New records obtained by EFF expose additional issues with Medicare’s AI-driven prior authorization program and show why we need stronger legal limits around government use of automated decision-making . EFF sued the government back in March for information about the Wasteful and Inappropriate Service Reduction (WISeR) model , a new Medicare program that uses AI to evaluate prior authorization requ
