A Minnesota lawsuit alleges that UnitedHealthcare and naviHealth used the nH Predict model in some Medicare Advantage post-acute-care decisions; UnitedHealth disputes that the system automatically denied claims, and the cited court record does not resolve the allegations on their merits.
What the lawsuit alleges about nH Predict
The Minnesota civil case concerns coverage for Medicare Advantage members’ post-acute care. Plaintiffs allege that UnitedHealthcare and naviHealth used a program called nH Predict to make predictions that were used to deny or cut off coverage, and that the model’s output displaced physicians’ or clinical staff’s judgment.
Those are allegations in a civil lawsuit, not established findings that the companies automatically denied benefits. The cited court document records the claims and procedural rulings; it is not a final decision finding that the alleged practices occurred.
Model input is not the same as an automatic coverage decision
The distinction matters. A system may generate a prediction that staff use in a coverage process; that does not, by itself, show that software made the final decision or automatically denied every claim. The lawsuit alleges a problematic use of model output, but the available court record does not establish the full decision process or prove the allegations.

UnitedHealth rejects the claim that it uses AI to automatically deny claims. STAT quoted the company’s position as: “any allegation that UnitedHealthcare uses an AI algorithm to automatically deny claims is false.” STAT also reported allegations that employees were advised not to depart from the model’s calculations. That account remains contested; it is not a court finding that staff were required to follow the model.
What is known about naviHealth and the system’s history
STAT reported that UnitedHealth acquired NaviHealth in 2020 and phased out the NaviHealth brand in 2024, while related algorithms were said to remain in use. That reporting does not establish that Thompson personally deployed nH Predict, nor does it settle how the model was used in individual coverage decisions.

The AI-denial allegations and the murder are separate matters. The U.S. Department of Justice announced charges against Luigi Nicholas Mangione in connection with the December 4, 2024, killing of UnitedHealthcare CEO Brian Thompson in Manhattan. A charging announcement is not a conviction, and the cited materials do not establish that an alleged insurance policy caused the murder.
The Associated Press reported that ammunition was inscribed with the words “deny,” “defend” and “depose,” a phrase it said echoed “delay, deny, defend,” language used by critics of insurance companies. The reported wording does not, on its own, establish motive or prove a connection between the killing and the nH Predict allegations.
Quick Recap
How to read the headline claims and figures
- “Thompson deployed the AI”: The cited sources do not establish that he personally introduced or deployed nH Predict.
- “The AI automatically denied benefits”: Plaintiffs allege that model predictions were used in post-acute Medicare Advantage coverage decisions; UnitedHealth denies automatic AI claim denials. The cited court record does not decide that dispute.
- “It denied benefits for all sick people”: The allegations concern a particular coverage context, not all UnitedHealthcare policies or every benefit claim.
- “The model had a 90% error rate”: The cited authoritative materials do not establish a universal 90% error rate. It should not be treated as a proven figure.
- Company scale: In a December 4, 2024 profile, the Associated Press reported that UnitedHealthcare provided coverage to more than 49 million Americans. That figure describes the company’s reported reach, not the number affected by the lawsuit’s allegations.
