New documents raise more questions about Medicare’s AI prior-authorization experiment

Newly surfaced documents are adding to scrutiny of Medicare’s AI prior-authorization experiment, according to STAT News, which covered the development in the November 12 edition of its STAT Health Tech newsletter. The outlet reports that the paperwork raises additional questions about how the program is being run, though the newsletter item is framed as one part of a broader roundup rather than a standalone investigative piece.

The same STAT Health Tech dispatch also covers two other developments in health technology. One concerns Oura, the wearable ring maker, and what STAT describes as a significant bet the company is placing on artificial intelligence. The other describes an effort to build what STAT calls a “rumble strip” for clinical chatbots, a safeguard mechanism intended to catch or slow problematic outputs from AI systems used in clinical settings.

STAT’s coverage does not, in the material provided, detail the specific contents of the new documents on the Medicare prior-authorization program, nor does it specify which agency or contractor is implicated beyond the Medicare program itself. The item is presented as developing coverage, with STAT signaling continued attention to the prior-authorization experiment in future reporting.

Readers seeking the underlying documents or fuller technical detail are directed to STAT News’ original article, published November 12, 2026.
