Case Summary

Expanded class action lawsuit targeting UnitedHealthcare's use of artificial intelligence to deny insurance claims for elderly and disabled patients. The lawsuit builds on earlier filings and alleges that UHC's AI system routinely overrides treating physicians' determinations of medical necessity. Internal documents cited in the complaint reportedly show the algorithm has been set to reject a fixed percentage of post-acute care claims regardless of individual patient circumstances, effectively making coverage decisions based on cost targets rather than medical need.
