Medicare's artificial intelligence preauthorization effort drew criticism in new documents released Tuesday. The documents depict a hastily implemented rollout. They also show strikingly high rejection levels. News reports point to major treatment delays from the pilot effort. MarketWatch reported that Medicare is using AI to approve claims, and that the result has been alarmingly high denial rates. Newsweek also reported the significant care waits. STAT also reported about the released records.

Separately, Medicare intends to broaden a pilot covering tech for managing chronic conditions. STAT covered that planned expansion.
