Herres had to fight for a drug her doctor had already prescribed, but Cuban’s new idea is about everything that happens before a prescription — the questions, symptoms and check-ins that fill the space between appointments.
If he were a doctor, Cuban said he would “offer to sit with the patient and configure their Claude, ChatGPT, Gemini and Grok” — loading the apps with instructions, skills and ready-made prompts that keep both the patient and the doctor in the loop.
He even drafted the prompt himself, addressing it to the AI directly: “LLM, every day at 5 p.m. I want you to ask Joe the following questions, and show him your response. Upon completion, I want you to email me everything in this chat.”
From there, the loop runs on its own. Each morning, the AI watches the patient’s email for new questions the doctor has sent over, then works them into its check-ins. “Rinse and repeat,” Cuban wrote. “Help the patient use AI to help you help the patient.”
Patients already use AI, but doctors never see it
Plenty of patients are already doing half of what Cuban describes. A West Health-Gallup survey released April 15 found that one in four U.S. adults has taken a health question to an AI tool, but the answers they got never reached a medical record.
Now, compare that with the channel patients use to reach their actual doctor. Since November 2022, Cleveland Clinic has billed for MyChart messages whenever answering one pulls a clinician into more than five minutes of medical judgment — and for anyone whose plan doesn’t cover the charge, the bill can reach $50 a message. At UW Medicine, an uncovered medical-advice message runs $33 to $104.
The charges haven’t slowed anyone down. Cleveland Clinic saw messages fall off for roughly a month once billing began — then growth came right back, at 5% in 2023, nearly 16% in 2024 and almost 19% in 2025, Sarah Hatchett, the system’s senior vice president and CIO, told Becker’s Hospital Review.
People clearly want an ongoing line to their doctor between visits, and Cuban’s setup would give the doctor some say over what comes through it.

How Cuban was able to help Herres
As Moneywise reported, Herres had been on everolimus — a drug that stops her immune system from attacking her transplanted heart — since she was a preteen. When Elevance Health pulled her coverage last year, she took to Facebook to share her plight. Within a day, her coverage was restored — priced at $1,000 per 90-day supply, up from the $180 she’d been paying.
