What happened
EFF sued the U.S. Centers for Medicare & Medicaid Services (CMS) in March to obtain records about the WISeR AI prior‑authorization model. The litigation resulted in the release of about 1,000 pages showing widespread delays, high denial rates, and financial incentives for vendors. The documents highlight concerns about patient harm and lack of transparency in the AI‑driven Medicare program.
