How to dispute a medical bill, with or without insurance
Get an itemized bill, compare it with your EOB or estimate, ask billing about specific lines in writing, and keep a record. If you’re insured, ask your insurer about how the claim was processed. If you’re not, check your good faith estimate and ask about assistance.
1. Gather your records
- The bill and an itemized version
- Your latest EOB, if you used insurance
- Any estimate and your receipts
2. Find specific questions
Look for repeated lines, dates that don’t match and totals that don’t add up. Our free Bill Check looks for these on your device.
3. Using insurance
Compare your bill’s amount with your share on the latest EOB. If they differ, ask billing which claim decision they used, and ask your insurer how to request a review.
4. Not using insurance
Ask about self-pay discounts and financial assistance. If a bill is at least $400 over a provider’s good faith estimate, you may be able to dispute it.
5. Keep it in writing
Note dates, names and reference numbers. Ask how the account will be handled during the review, and don’t ignore the bill.
Common questions
Should I stop paying while I dispute?
Don’t stop a payment plan or ignore a bill on your own. Ask how the account will be handled, and get professional advice if the debt is disputed or in collections.
Does a dispute guarantee a lower bill?
No. It gets you answers, and some bills turn out to be correct.
