UnitedHealth Says AI Now Runs Every Function of Its Business

Every claim UnitedHealth processes, every prior authorization it reviews and every patient interaction it handles now runs through artificial intelligence (AI).

The company is turning that internal overhaul into a commercial product line.

AI-powered prior authorization is achieving a 96% first-pass approval rate.

The company committed this quarter to eliminating 30% of prior authorization volume by year-end and nearly two-thirds of prior authorization requirements for pediatric care.

Those efficiencies are flowing straight to the bottom line, with second-quarter operating earnings up 55% year over year.

At Optum Health, which delivers care directly to 20 million patients, ambient listening AI tools are available to 70% of employed clinicians and are on track to reach 90% by year end.

The technology transcribes patient encounters in real time, removing the documentation burden that drives clinician burnout.

Optum CEO Patrick Conway said during the call that the tool has produced a 90% reduction in cognitive burnout among clinicians who use it.

Conway also noted that AI is helping nurses summarize complex patient cases 40% faster.

Enhanced care transition support has driven a 10% reduction in hospitalizations in the Western and Southern regions since late last year.

Home health pilots have cut readmissions and reduced skilled nursing facility stays.

In claims processing, complex cases that once required manual review are now processed automatically and with higher accuracy.

“Very complex claims that we never before thought we would be able to automate, we’re able to automate those and process those with higher accuracy,” said Tim Noel, CEO of UnitedHealthcare.

Patient-facing hours expanded by nearly 200,000 in the first half of the year as AI-assisted scheduling cut wait times for specialist appointments.

Optum Insight is converting those internal tools into commercial products sold to health systems and payers outside UnitedHealth.

About a third of Optum Insight’s technology investment this year is going toward that commercialization effort.

A digital prior authorization product launched last quarter under the Optum Real branch has processed roughly half a million prior authorizations and saved 69,000 administrative hours for external clients.

Value Connect, an AI insights platform embedded directly in provider electronic health records, is showing a 17% reduction in pharmacy costs in early client deployments.

Hemsley said every internal function, including HR, finance, legal and clinical operations, is being rebuilt around AI.

The efficiency gains from that work will become the product Optum Insight sells externally.

About a third of Optum Insight’s investment this year is going toward commercializing internal use cases for outside clients.
