UnitedHealthcare sued over AI denying elderly patients prescribed care
The insurer's algorithm allegedly overrides doctors and forces patients from nursing homes with a 90% error rate.
What to know
- UnitedHealthcare's nH Predict algorithm allegedly overrides physician orders and denies Medicare Advantage patients coverage for prescribed post-acute care, forcing early discharge from rehabilitation facilities.
- The algorithm has a reported 90% error rate and fails to account for patient comorbidities and in-stay complications like pneumonia or COVID-19.
- The lawsuit seeks class-action status, potentially covering tens of thousands of affected patients, and comes alongside a Stat News investigation corroborating the claims with internal documents and former employee testimony.
- UnitedHealth refuses to disclose the algorithm's methodology to patients and physicians, citing proprietary concerns, while overriding medical judgment on care determinations.
AI deployment in healthcare requires urgent accountability and transparency; this case exemplifies systemic profit-over-patient-safety incentives.

Stat News investigation and federal lawsuit reveal nH Predict's flawed denials
A lawsuit filed in US District Court for the District of Minnesota, brought by estates of two deceased patients denied coverage, alleges the algorithm has a 90% error rate and systematically denies prescribed care. A parallel Stat News investigation, based on internal documents and interviews with former NaviHealth employees, corroborates the claims.
“By the end of my time at NaviHealth I realized: I'm not an advocate, I'm just a moneymaker for this company. It's all about money and data points.”

background
UnitedHealth deploys nH Predict algorithm for Medicare Advantage coverage decisions — UnitedHealth subsidiary NaviHealth began using the nH Predict algorithm to estimate post-acute care needs for Medicare Advantage patients. The algorithm pulls from a database of 6 million patient cases and estimates medical needs, length of stay, and discharge dates based on patient demographics and physical functions.
