UnitedHealth's $3 billion AI push has bots calling doctors

UnitedHealth Group Inc. plans to invest $3 billion in AI over 2026 and 2027, positioning artificial intelligence at the core of its turnaround strategy. The company is piloting systems that read aloud summaries of medical charts for nurses visiting patients at home, and AI agents that listen to millions of consumer calls to pinpoint reasons for complaints. In one trial, bots even call doctors’ offices to schedule appointments, demonstrating how automation could speed access to care. Executives say the technology has produced a roughly two-to-one return by cutting manual work and boosting efficiency, with potential to lower patient frustration and operating costs. Industry context notes an $80 billion annual burden in administrative transactions, with Optum Real processing about a billion transactions since last year. Analysts cite cost-saving potential in prior authorization, while public trust remains a hurdle; a Gallup poll shows 69% distrust in businesses using AI responsibly. The company faces litigation over prior authorization algorithms, though UnitedHealth argues the algorithm isn’t used to decide coverage and regulators have flagged related denials in some NaviHealth cases.
