What happened
In March 2026, a federal judge ordered UnitedHealth Group to provide extensive discovery documents in a class-action lawsuit. The litigation alleges the company used its nH Predict AI tool to deny claims for skilled nursing facility care. Plaintiffs claim the tool was used to prematurely terminate coverage by overriding the clinical judgments of treating physicians.
What broke inside the model
- 01 · TriggerAn agent plans a multi-step task.
- 02 · Model stepIt chooses a wrong or destructive action.
- 03 · Control gapNo confirmation gate guards the write.
- 04 · FailureThe action commits to a system of record.
- 05 · ConsequenceData is changed or destroyed irreversibly.
A wrong action commits, and the step is written before anything can stop it.
The nH Predict algorithm allegedly supplanted physician clinical judgment with automated predictions of patient recovery timelines. This automation led to the premature denial of coverage by prioritizing algorithmic stay-length predictions over individual patient medical needs.

Realm can sit inline on the agent's action path and require that a destructive or high-consequence action clears a real check before it executes, so 'delete and recreate' or a wrong write is stopped at the moment of intent, not explained in the post-mortem.
