How to dispute a medical bill

Getting a medical bill that looks wrong is stressful. The good news: you have more power than you think, and the process is more manageable than it looks. Here's the path, start to finish.

1. Get the itemized statement first

The bill you received in the mail is usually a summary: a few vague categories and a total. You can't dispute what you can't see. Call the billing office and request a fully itemized statement that lists every charge with its billing code. You have the right to ask for this, and providers routinely produce it on request.

2. Review it line by line

Look for the common patterns: the same code appearing twice on the same date, charges for services you don't remember receiving, a visit level that seems high for what happened, and lab work split into many separate lines.

3. Call before you write

A polite, specific phone call resolves more than people expect. Ask about specific line items and take notes: the date, who you spoke with, and any reference number.

4. Put your dispute in writing

If the call doesn't resolve things, send a written appeal letter. Reference your account number, list each charge you're questioning and why, and request a written response. Send it certified mail so there's a record it arrived.

5. Follow up on a schedule

Follow up in writing around day 14, day 30, and day 45 if you haven't received an answer. A paper trail changes how seriously your dispute is treated.

6. Run financial assistance in parallel

While your dispute is open, apply for the provider's financial assistance program if there's any chance you qualify. It's a separate process, and pursuing both at once is usually the fastest path to a smaller bill.
