Medicare's AI Prior Authorization Rollout Was Rushed, and Records Show Delays and Bad Denials
Ourtake
Records obtained by EFF show delayed determinations and questionable denials in WISeR's first months, with patients and providers already affected.
What happened
Records released by EFF through a lawsuit show CMS sent requests for information or corrective action plans to at least four of six vendors running WISeR, an AI system that evaluates Medicare prior authorization requests. The letters cite delayed determinations, technical failures and denials that appear inaccurate. The public still lacks details on vendor safeguards and data use.
