# STAT+: Medicare's AI prior authorization pilot was rushed and full of problems, new documents reveal

> Newly surfaced documents suggest that a Medicare experiment in using AI to approve or deny care was rushed into service and quickly ran into trouble. The pilot, known as WISER, was designed to apply automated systems to prior authorization, the process that decides whether a treatment gets covered before a patient can receive it. According to the records, the hurried launch led to delayed care in at least some cases. Prior authorization is already one of the most resented parts of American health care, a paperwork gauntlet that can hold up treatment even when doctors agree it is needed. Layering AI on top raises the stakes, because an automated denial can carry the veneer of objectivity while still being wrong, and because patients may have little visibility into how a decision was reached. The reporting matters as a real-world test of AI in high-stakes public systems, not a hypothetical. It shows how the pressure to deploy quickly can collide with the caution such decisions demand, and it hands ammunition to critics who worry that efficiency is being prioritized over the people waiting on the other end for care.
