BRM has an interesting piece on hospital bills

The man’s sister-in-law was ready to pay it. He asked her to wait. He requested an itemized bill with CPT codes, the universal billing codes hospitals use, and fed the whole thing into Claude, an AI chatbot.

Within minutes, Claude found duplicate charges, services billed as "inpatient" even though the patient was never admitted, supply costs inflated by 500% to 2,300% above Medicare rates and charges for procedures that never happened. He cross-checked with ChatGPT. Both AIs agreed. He wrote a six-page letter citing every violation by name.

The hospital dropped the bill to $33,000. An 83% reduction. Zero medical training. A $20 app.

Holy crap. I'd not have thought of checking all that.
