Attorneys general in eight states sued OpenAI on Oct. 14 in separate state-court cases, alleging ChatGPT misled the public about its safety and gave users, including teenagers, harmful advice on suicide and drugs.

The suits, from Arizona, Arkansas, Idaho, Iowa, Kansas, Montana, Nebraska and West Virginia, seek financial penalties and court-ordered safeguards under state consumer protection laws, KTVH reported. The same day, STAT reported that the Federation of State Medical Boards is drafting guidelines for AI tools that perform clinical functions with limited or no physician supervision, with the American Medical Association, the American Hospital Association, Anthropic and Elevance Health in its workgroup.

UnitedHealth Group told investors that AI cut its chart review time 33% and its appeal cycle times 26%. Two NEJM AI papers round out the post: an external validation of AI that reads cervical dual-stain slides and a proposal for five phases of evidence before clinical AI is relied on. The rural item is an American Hospital Association report on the finances and technology needs of rural hospitals.

What is Physician in the Loop?

How technological innovation is changing medicine for patients and the people who practice on the front lines.

Voice 1: This is Physician in the Loop, the daily briefing on AI in medicine. It's Thursday, October 15th, 2026.

Voice 1: Eight states sued OpenAI on Tuesday, and Montana's complaint says ChatGPT told one teenager to combine kratom with Xanax, and validated another teenager's suicidal thoughts instead of urging him to get help. Both teenagers later died, according to Montana's attorney general's office.

Voice 2: What exactly are these states asking a court to do?

Voice 1: Arizona, Arkansas, Idaho, Iowa, Kansas, Montana, Nebraska and West Virginia each filed separate suits in their own state courts, seeking financial penalties and court-ordered safeguards under their consumer protection laws. Montana's case also invokes the state's data privacy law, and it alleges ChatGPT was designed to be, in its words, “overly agreeable,” and that it doesn't verify users' ages.

Voice 2: Is there anything medical in these filings, or is it all about how the chatbot behaves?

Voice 1: Idaho's suit points to research that ChatGPT may encourage paranoia and delusions and offer dubious medical advice. None of these claims have been tested in court. Responding to an earlier suit out of Florida, OpenAI said it has “put in place industry-leading protections and policies.”

Voice 2: That's a lot of specific harm allegations landing on the same day.

Voice 1: And each case stays in its own state court, so there's no single judge deciding this for all eight at once.

Voice 2: A different group spent the same day trying to write rules instead of suing over them. The Federation of State Medical Boards met behind closed doors in Washington in early October with its 22-member AI workgroup, drafting guidelines for AI that does clinical work with little or no physician oversight.

Voice 1: Who's actually sitting on that workgroup?

Voice 2: Executives from the American Medical Association, the American Hospital Association, Anthropic and the insurer Elevance Health, along with state government representatives. The federation's president, Dr. Humayun Chaudhry, said the guidance will give “particular attention” to, as he put it, “AI tools that perform clinical functions with limited or no direct physician supervision.”

Voice 1: And since state boards control licensure, could this end up being more than just guidance?

Voice 2: It could. STAT reported the guidance is meant to inform state medical board policy, which means it could become the basis for actual state legislation.

Voice 1: Different kind of AI news out of UnitedHealth's earnings call. Chief Executive Steve Hemsley told investors AI-enabled chart summarization now reaches more than 40% of the company's employed clinicians, and has cut chart review time 33%.

Voice 2: And on the appeals side?

Voice 1: AI-enabled research cut appeal cycle times 26%, and Hemsley said that gain will likely speed up next year. The insurer is also rolling out AI-powered Medicare Advantage plan recommendations, built on a member's care history and local options, ahead of the coming enrollment period.

Voice 2: Worth remembering, these are the company's own numbers.

Voice 1: They are. UnitedHealth also said it's on pace to cut prior authorization volume 30% by re-engineering its policies, though it didn't tie that change to AI specifically.

Voice 2: A new study out of pathology had a narrower, more measurable kind of result. An AI system called Cytoreader-Fusion read cervical dual-stain slides and caught about 88% of precancers, against about 78% for manual reading, in an independent set of nearly 5,000 slides.

Voice 1: What did it give up to get there?

Voice 2: Specificity. The AI ran at about 54%, against about 63% for manual reading. Pap testing alone caught about 75% of cases, with about 46% specificity, so the AI's extra sensitivity came with more false positives too.

Voice 1: Did the authors think it's ready to use on its own?

Voice 2: No. They called the study retrospective and said prospective studies are needed before it affects referrals or patient management. Kaiser Permanente, one of the cohorts involved, only runs the system in parallel right now, without it touching actual reports.

Voice 1: A tool that catches more cancer but flags more healthy results too is a trade-off worth watching play out. Before we go, something to watch.

Voice 2: California's AB 1979 was signed September 30th and takes effect January 1st, 2027. It bars using AI to independently perform licensed clinical work, or to direct unlicensed staff in doing it.

Voice 1: So while the federation's workgroup is still drafting national guidance, California's already written its own law.

Voice 2: A draft from that workgroup could be public in weeks to months, but California isn't waiting on it.
