How to use AI to check a medical bill safely
AI can help you understand a confusing bill, as long as you remove your personal details first and check its answers.
Physician Dr. Virgie Bright Ellington teaches a simple three-step method that I think every patient should know. Here it is in plain language.
Step 1: Ask for the itemized bill
Do not pay from the summary bill. Call the billing office and ask for an itemized bill that lists the billing code for each charge (CPT or HCPCS codes). Also ask what was sent to your insurance company and what it paid. Federal privacy law gives you the right to see and get a copy of your medical and billing records.
Step 2: Check every line
- Look up each code and make sure you actually received that service.
- Look for duplicates, items you never got and days you were not there.
- Compare the price to what Medicare pays for the same code. Medicare's fee schedule lookup is free and public. Dr. Virgie uses it as a yardstick for a fair price.
- Compare the bill to the Explanation of Benefits (EOB) from your insurer. They should match.
Step 3: Call back, ask for a fair amount and a payment plan
Call the billing office with what you found. Ask them to remove errors, ask for a fair price, and ask for an interest-free payment plan at a monthly amount you can actually afford. Write down the date, the name of the person you spoke with and what they agreed to.
A safe AI prompt for your itemized bill
First remove your name, date of birth, address, account numbers and insurance ID. Then paste only the codes, descriptions and prices, and try:
I have an itemized medical bill. For each line below, explain in plain language what the code means, flag possible duplicates or charges that do not fit the visit, and list questions I should ask the billing office. Do not guess prices. Tell me when you are unsure. [paste codes, descriptions and prices only]
Then check what it tells you against the bill and your insurance statement. AI can be confidently wrong.
When to get help
If a bill is large, a denial seems wrong or you cannot make sense of it, a certified medical bill advocate can help. Dr. Virgie's company, Medical Bill Shield, works with employers on medical bill audits, and her site CrushMedicalDebt.com has free resources and her book.
