Medicare's artificial intelligence preauthorization effort attracted scrutiny in papers released Tuesday. The records portray an accelerated launch. They also show strikingly high rejection levels. News reports describe lengthy treatment delays from the initiative. MarketWatch reported that Medicare is using AI to approve claims, and that the result has been alarmingly high denial rates. Newsweek also reported the treatment delays. STAT also reported on the documents.
