TL;DR
What did u/Kindly-Ambition-1796 use Claude for?
Faced with a medical bill full of codes they couldn't read, someone asked Claude to explain every line and flag anything wrong. It found two duplicate charges and drafted a dispute letter citing the codes, and the revised bill came back far lower.
What they did
Instead of paying a bill they were sure was wrong, they pasted the whole itemized bill into Claude and asked it to explain each line and say whether anything looked incorrect or negotiable. Claude flagged two duplicate charges, explained what a good-faith dispute letter should contain, and wrote one that cited the specific billing codes. They sent it almost as written.
How it went
The bill came back at 180 instead of 1,200.
"it saved me a thousand dollars and an argument I didn't know how to have."

Worth knowing
- This is one person's bill, and billing rules vary by country and insurer. Check every charge and code it flags against the bill before you send anything, and remove personal details you don't need to share.
- Price check: Claude: free plan; Pro: US$20/month, or US$17/month on a yearly plan (US$200/year) (checked Nov 1, 2026).

Try it yourself
Paste this into a chatbot, then add your own details underneath.
Here is an itemized bill I received: [paste bill, with my name, address and account numbers removed]. Explain each line in plain English. Flag anything that looks duplicated, wrongly coded or open to negotiation, and say why. Then draft a short, polite dispute letter that lists only the charges I'm questioning, with their codes, and asks for a corrected bill.
