Senate Republicans Block Democrats’ Bid to End Medicare AI Prior Authorization Pilot

On Thursday, July 16, 2026, Senate Republicans blocked a Democratic effort to halt a Trump administration pilot program within Medicare that employs artificial intelligence to approve or deny physician-ordered care. The resolution sought to invoke the Congressional Review Act (CRA) to end the program but failed in a 46 to 50 vote strictly along party lines. This outcome allows the AI-driven prior authorization pilot to continue operating under Medicare.

The vote highlights ongoing partisan divisions over the use of AI technologies in healthcare policy and Medicare administration.
