How to dispute a hospital bill
Disputing a hospital bill means asking the billing office to check specific charges and correct the ones that are wrong, before you pay. The order to do things in, who to call first, and how to ask them to hold the account from collections while you sort it out.

The short version
- Don't pay a bill you think is wrong, but don't ignore it. Call billing and ask them to note the account as under review.
- Get the itemized bill and your insurer's EOB, and compare them.
- Call with specifics (account, date, code, amount) and write down who you spoke with.
- Still not fixed? Ask for a supervisor, appeal with your insurer, or contact your state.
Many hospital bill problems can be fixed with a phone call or two, as long as you make them in the right order and keep notes. Here's a sequence that works well.
Step 1: Don't pay yet, but don't ignore it
Paying a bill you think is wrong makes it much harder to get money back. Ignoring it is worse, because accounts can be sent to collections. Call the billing office early, tell them you're reviewing the charges, and ask them to note the account as under review.
Step 2: Ask for an itemized bill
The statement most people get is a summary. Ask for an itemized bill that lists every charge with its date, billing code (CPT, HCPCS or revenue code) and amount. You can't check charges you can't see.
Step 3: Get your EOB from your insurer
If you have insurance, your insurer sends an Explanation of Benefits (EOB) for each claim. It shows what the hospital billed, what the insurer paid, and what you owe. Download it from your insurer's website if you don't have the paper copy.
Step 4: Compare the three documents
- Does the amount the hospital wants match the "patient responsibility" on the EOB?
- Is any service listed twice on the same day with the same code and amount?
- Are there charges for things you didn't receive, or for a longer stay than you had?
- Did the insurer deny anything? Denials are often fixable with a call or an appeal.
Step 5: Call billing with specifics
A specific question gets a specific answer. Give the account number, the date of service, the code and the amount, and ask what they can do.
“Hi, I'm calling about account [number]. I'm reviewing my itemized bill and I see code [code] billed twice on [date] for [amount] each. Can you check whether that's a duplicate? While you look into it, can you put the account on hold so it isn't sent to collections?”
Write down the date, the name of the person you spoke with, and any reference number. If they agree to fix something, ask for it in writing or ask them to send a corrected statement.
Step 6: What if billing won't fix it?
- Ask for a supervisor or the patient financial services manager.
- Ask about the hospital's financial assistance policy if the charges are correct but unaffordable.
- If your insurer denied a claim, you can file an internal appeal (usually within 180 days of the denial for most plans) and then ask for an external review.
- Your state's insurance department or attorney general's consumer office can help with insurer or collection problems.
