Dispute a billing error

For when the itemized bill shows something wrong: a duplicate charge, a quantity that does not match the care you received, a service on a date you were not there, or an unbundled item billed separately. Names each disputed line and asks for a corrected statement.

The lever: A specific, line-by-line objection is an administrative task the billing office can act on — unlike "this bill is too high", which is not.

Re: Account [ACCOUNT OR BILL NUMBER] — dispute of specific charges
Date of service: [DATE OF SERVICE]

To whom it may concern,

I have reviewed the itemized statement for the account above and identified charges that appear to be incorrect. I am disputing the following line items:

[THE LINES YOU ARE DISPUTING]

Please review each item, correct any errors, and send me a corrected itemized statement. If you determine that a disputed charge is accurate, please explain in writing what the charge covers and what documentation supports it.

While this dispute is open, please do not refer this account to collections, and please note the dispute on the account file.

I am not disputing the remainder of the bill and intend to resolve the account once the charges above are clarified.

Sincerely,

[YOUR FULL NAME]

What this letter rests on

After you send it

Day 14Call to confirm the dispute is logged on the account and ask for the reference number. Note the date, time and name of the person you spoke to.
Day 30No corrected statement? Resend by certified mail, referencing your first letter and the reference number.
Day 45If the account has moved to a collector, the validation letter is the next step — the 30-day clock there starts from their notice, not from this dispute.

The case tracker turns this schedule into dated reminders for one specific bill, stored in your browser.

Frequently asked questions

What counts as a billing error worth disputing?

Duplicate charges, quantities greater than what you received, services on dates you were not there, canceled procedures still billed, and items that should have been bundled into a single code but appear separately. The check-your-bill checklist on this site walks the itemized statement line by line.

Do I need proof before disputing?

You need a specific observation, not a legal case. "Line 4 appears twice on the same date" is something the billing office can verify in their own system faster than you can. Attach discharge paperwork or appointment records if you have them, but do not delay the letter to hunt for documents.

Will disputing stop collection activity?

This letter asks the provider not to refer the account while the dispute is open — a request, not a right, at the provider stage. Once an account is with a debt collector, the FDCPA gives you a written 30-day validation window that does pause collection of the disputed amount, which is a different letter.

What if they say the charge is correct?

Ask for the explanation in writing, which this letter already requests. A written answer either resolves your concern or hands you something specific to escalate — to the provider's patient advocate, your insurer's appeals process, or your state's consumer protection office.
