AI Prior Authorization Denial Claims

Class actions target Humana's use of the nH Predict AI tool to automate prior authorization denials for skilled nursing facility care. Plaintiffs allege the tool denies coverage at rates far above what individualized clinical review would support, overriding treating physicians' recommendations.

Medicare Advantage plans must provide at least the coverage traditional Medicare would for the same services. Algorithmic denials ignoring individual patient circumstances arguably violate this equivalence requirement.

Risk Score Fraud Allegations

DOJ whistleblower lawsuits allege Humana systematically inflates Medicare Advantage risk scores -- submitting diagnoses to make patients appear sicker than they are to receive higher government payments. Chart review programs that identify additional diagnoses without ensuring active management are alleged to fraudulently inflate payments.

Who May Have Claims

Medicare Advantage members denied skilled nursing or post-acute care that treating physicians recommended may have appeal rights and civil claims. Whistleblowers with direct knowledge of risk score manipulation may be eligible for qui tam relator shares under the False Claims Act. Related: Veterans Guardian Lawsuit.

Status 2026

DOJ investigation and class action prior authorization claims are both active. No comprehensive settlement has been announced.
