EFF releases 1,000 pages of CMS records on AI-driven Medicare WISeR prior‑authorization program

EFF obtained about 1,000 pages of CMS documents through its FOIA lawsuit filed in March, revealing delays, denials, and financial incentives in the WISeR AI model. The records show requests sometimes waited up to 83 days and vendors denied 5,944 requests in the first three months. Providers report patient harm linked to the rushed rollout and technical failures.

Why it matters: The disclosure highlights how an AI‑driven Medicare prior‑authorization system may compromise patient access and raise privacy and bias concerns.
