Medicare's AI prior-authorization system cuts medical services sharply
Medicare deployed artificial intelligence to pre-approve treatments, resulting in a significant decline in medical services provided to patients.

What This Means
Medicare introduced artificial intelligence systems to pre-authorize healthcare services, and utilization of medical services dropped significantly immediately after deployment. The mechanism operates through approval gatekeeping: AI systems denying or delaying authorization for treatments reduces the volume of care delivered, directly suppressing demand for medical services and related provider revenue. This creates downward pressure on healthcare delivery volumes and raises questions about AI decision-making in coverage determinations.
