What to do before you pay a medical bill
Medical bills often contain mistakes, and the first number you see is not always the final one. A few phone calls can lower what you owe.
Don’t pay the first bill straight away
A bill can arrive before your insurer has finished processing the claim. Paying it right away can mean paying too much and then chasing a refund. You don’t have to ignore the bill, but you also don’t have to pay it the day it arrives.

The itemized bill
The first bill is often just a summary. Call the provider’s billing office and ask for an itemized bill, which lists each service, test, supply and medication with its own charge.
The Explanation of Benefits (EOB)
Your insurer sends this (or posts it in their online portal) after processing a claim. It isn’t a bill. It shows what the provider charged, what the insurer paid, and what it says you owe.
What you owe the provider should match the “patient responsibility” amount on the EOB. If it doesn’t, ask why before paying.
Common mistakes to look for
- The same charge listed twice
- Services, tests or medications you didn’t receive
- The wrong number of days for a hospital stay (check how admission and discharge days were counted)
- A claim sent to the wrong insurer, or not sent to insurance at all
- A claim denied for a fixable reason, such as a typo in your name or member ID
If you find a mistake, call the provider’s billing office, explain it, and write down the date, the person’s name and what they said. If the problem is with how the claim was processed, call your insurer.
Surprise bills and the No Surprises Act
Since 2022, federal law has protected most people from surprise bills, for example from an out-of-network doctor at an in-network hospital, or for most emergency care. In those cases you usually only owe your normal in-network cost-sharing.
If you’re uninsured or paying for care yourself, you generally have the right to a good faith estimate before scheduled care. If the bill is much higher than the estimate, you may be able to dispute it. The CMS No Surprises page explains both rights and how to file a complaint.
Ask for help paying
- Financial assistance (charity care). Nonprofit hospitals are required to have a written financial assistance policy. Depending on your income, it may reduce the bill or cancel it entirely. Ask for the application, even if you think you won’t qualify.
- Payment plans. Most providers offer interest-free monthly payment plans. Ask before putting a medical bill on a credit card.
- A lower price. You can simply ask whether there’s a discount for paying in full or for self-pay patients.
Do this today
- Ask the provider for an itemized bill.
- Find the matching Explanation of Benefits (EOB) in your insurer’s portal or mail.
- Compare the two line by line, and circle anything that doesn’t match.
- Ask the billing office whether they have a financial assistance policy and a payment plan.
