UnitedHealth also expects AI-driven improvements to contribute to nearly $1 Bn in operating cost reductions this year.
UnitedHealth Group has expanded its artificial intelligence (AI) strategy with a planned $3 billion investment across 2026 and 2027, introducing AI-powered bots that can contact doctors' offices to schedule appointments while automating several administrative tasks across its healthcare businesses.
The insurer says the technology is improving efficiency, lowering administrative costs, and helping simplify patient interactions.
As one of the largest healthcare companies in the United States, UnitedHealth operates both insurance services and healthcare technology businesses through Optum, making administrative efficiency a key focus.
UnitedHealth has now integrated AI into hundreds of day-to-day workflows. Among its latest applications are AI-generated summaries of patient medical records that nurses can listen to while travelling to home visits, systems that analyse millions of customer service calls to identify recurring complaints, and AI agents that contact physicians' offices to arrange patient appointments.
The insurer expects the investment to deliver measurable financial returns. Executives have said the company is already seeing a two-to-one return on AI investments through productivity gains and operational efficiencies.
UnitedHealth also expects AI-driven improvements to contribute to nearly $1 Bn in operating cost reductions this year.
The company's technology division, Optum Insight, has significantly expanded its AI capabilities. According to Chief Executive Officer Sandeep Dadlani, UnitedHealth now supports more than 1,000 AI use cases, employs approximately 20,000 AI engineers, and provides staff access to 117 large language models.
"We are not getting into diagnostic AI," Dadlani said.
He added that nearly 99% of the company's AI applications remain focused on administrative functions rather than clinical decision-making.
UnitedHealth also continuously monitors deployed AI systems for unintended behaviour and has withdrawn certain models when performance drift has been detected.
The company operates an internal review board comprising clinicians, medical ethicists, privacy specialists, legal experts and technologists to evaluate every new AI application before deployment.
UnitedHealth has also sought to reassure patients that AI is intended to support, not replace, human oversight.
