AI for medical bills, insurance and doctor visits: 32 real cases with prompts

A Topretirements blogger's Medicare Part D drug plan wrote to say the 2027 premium would rise from $98.30 to $126 a month. They asked ChatGPT for cheaper options, giving their Florida ZIP code, their medications and preferred pharmacies. It suggested several, including a plan at $5.30 a month in their area, $1,448.40 a year less in premiums. They didn't switch on ChatGPT's word alone: as their insurance agent also advised, they checked it in Medicare's official Plan Finder, which confirmed the switch made sense, and enrolled. They get most prescriptions through the VA, so the cheapest premium suited them; they note others need to compare total yearly cost.

Ramesh Raman dislikes filing reimbursements, so they pulled 12 months of receipts from three retailer accounts and had an LLM classify every item as FSA-eligible or not. They checked the ones it got wrong themselves until every eligible item had a PDF receipt, then pointed Cursor at their reimbursement portal to file the claims. From 600 transactions it submitted 15 claims worth $242.87, pausing for approval before every upload; they reviewed everything at the end. The first upload took about 2 minutes and the last under 30 seconds. It took about an hour, for a chore they'd put off for months, and mostly recovered small forgotten buys like Tylenol.

Financial planner Mike Palmer's itemised statement for a surgery was $3,802 in confusing codes and offsetting entries; insurance covered $1,390, leaving $2,412 out of pocket. Palmer saved the bill details as a PDF without personal information and asked Gemini what the codes meant and whether the coverage was correct. Gemini explained each line, confirmed the write-offs showed in-network pricing, and flagged an office consultation fee as likely contested, since insurers usually bundle a same-day evaluation into the procedure. There had been no separate consultation, so Palmer called the provider to dispute it, and they removed the $269 fee.

DANN's pain started out of nowhere on a Friday night and within twenty minutes they could barely walk; the plan was to take painkillers and sleep it off. They asked Claude first, and it said this could be testicular torsion, that there's a 4 to 6 hour window, to go to the ER now, not to eat or drink in case of surgery and not to drive themselves. They went. The first ER untwisted it and sent them home; at 3am the pain came back and after a second visit they were taken by ambulance to a bigger hospital, staying three days. Torsion was never confirmed because it was untwisted before an ultrasound, but DANN is home, healing and kept everything.

Two years after an ER visit, Jackie Davalos got a collections notice saying $22,604 was owed to the hospital, having never received a bill; the records wrongly listed Davalos as uninsured. A first dispute only removed one medication charge. Davalos's partner, Walter Kerr, uploaded the billing and medical records to Claude and asked whether they had any further recourse. Claude suggested several arguments, including that legal requirements on debt and insurance might not have been met. Using many of them, Kerr wrote to executives at the hospital and its parent company, and shortly after the hospital waived the entire bill, later acknowledging a clerical error. A legal aid lawyer who reviewed it said some of Claude's analysis was right but it misunderstood some of the laws it cited.

Ved Kamat, who lives in Japan, gets the same pollen-allergy prescription every month and finds clinic booking sites awkward, with odd layouts and the same details asked for again and again. They had Claude in Chrome do the booking: it found the booking page, chose the return-patient appointment type, picked the earliest slot as asked and filled in the patient details. Kamat only had to type their password when Claude asked; payment details would also have stayed with them. They plan to hand over more non-critical bookings.

Chris L.'s family spent about $19k on healthcare in a year that wasn't especially bad health-wise, because they'd hit the out-of-pocket maximum on a plan that didn't fit their needs. During open enrollment they photographed the pricing and coverage pages of the enrollment booklet and gave them to ChatGPT, with the care they expected. After 5 and a half minutes it compared the PPO, Gold and Bronze plans, explained how an FSA and an HSA would work out, and gave best- and worst-case yearly costs for each. They then asked about the costs in between those two extremes and got another detailed answer. They checked the output with two other models, which gave the same numbers, and expect to pay between $2,600 and $16,500 in 2026, saving at least $2,500 compared with the year before. It took them under 20 minutes.

Jacinth Paul Z submitted a ₹89,000 hospitalisation claim, of which ₹65,000 was marked claimable, and sent every required document within a week. After three months of silence the insurer asked for more documents three times, each needing a trip to the hospital. The fourth time, Jacinth used ChatGPT to draft a firm, legal-toned letter saying enough documents had already been submitted, that the requests looked like a delay tactic, that no more would be sent, and that HR was being told how the claim had been handled. Jacinth uploaded the letter instead of more documents, and the claim was approved the next day for ₹85,000.

Carrie Liken asked Gemini to book a yearly eye appointment at their usual optician. It didn't work at first because the Zocdoc app needed switching on in settings and calling with '@zocdoc'. Once it was on, Gemini offered times for only one of the practice's doctors, not Liken's. Google's business listing showed the same single doctor, so Liken went to the practice website, found their doctor listed and booked there directly.

When home care didn't clear up their symptoms, X user David Lermarl had Grok help write the online request form for their GP practice. They say the appointment took less than five minutes, they came away with the medicine they needed, and the doctor thought the approach was great, while noting it may not work every time.
