Ask a collector to validate a debt
Ask a collection company in writing to prove what it says you owe, and to pause collection while you appeal and check the bill.
- Private: nothing leaves this tab
- A template, not legal advice
When to use this, and what it is not
When to use this. When a collection company contacts you about a medical bill and you are not sure it is right, or the care is the subject of an insurance denial or appeal. This letter asks politely and in plain words. It does not rely on a specific consumer-debt law deadline, because this site has not verified one. It does not replace your insurance appeal.
This is a template, not legal advice. Read it, change anything that is not true for you, and send it only when you are satisfied. Your notice and your plan document control.

Re: Ask a collector to validate a debt Plan: [Name of the health plan] Member ID: [Member ID] Claim or reference number: [Claim or reference number]
To whom it may concern:
I received a notice dated [Date on the collector's notice] saying I owe [Amount the collector says you owe] on an account with the number [Account number on the collector's notice]. It names [Doctor, hospital or pharmacy] as the original provider. I am not sure this amount is correct, and I would like to see proof before I discuss payment.
Please send me, in writing: 1. The name and address of the original provider, and the date or dates of service. 2. An itemized statement showing each charge, any payment or insurance adjustment, and any interest or fees that were added. 3. Proof that you own this debt or are authorized to collect it. 4. Whether you have reported this account to any credit reporting company, and when.
The amount I owe may depend on a decision by my health insurance plan. I ask that you pause collection while you gather this information.
Please contact me in writing only, at the address in this letter. I am not refusing to deal with this account. I am asking for the information I need to handle it correctly.
Enclosures: 1. Copy of the collector's notice 2. Your plan's Explanation of Benefits or denial letter, and your appeal 3. Proof of any payment you made
Sincerely, [Your name]
Before you send it
Send it to the address on the collector's notice, by mail with tracking, and keep a copy and the receipt. Do not give your Social Security number or bank or card details to a collector by phone or in this letter.
What to enclose
- Copy of the collector's notice
- Your plan's Explanation of Benefits or denial letter, and your appeal
- Proof of any payment you made
What happens next
- Write down the date you sent it. Keep every notice and envelope you receive.
- The rules on collectors, interest, lawsuits and credit reports are set by consumer-debt law, and this site has not verified them. Before you rely on any deadline or right, confirm the current rules with the Consumer Financial Protection Bureau or a consumer-law legal aid office.
- When the collector answers, compare its statement with your plan's Explanation of Benefits before you pay anything.
- Also send the bill hold letter to the original provider, and ask about financial assistance if the care was at a hospital.
- If you receive court papers, do not ignore them. Contact a legal aid office promptly, because court papers carry their own deadlines.
