If a medical collection appears on your credit report with the wrong balance, belongs to someone else, or should be excluded under the credit bureau's policy, you can dispute it yourself. Use the free sample letter below to identify the entry, explain the problem, and request a specific correction.
Quick answer
This template is for Equifax, Experian, or TransUnion. If you received a collection notice and need the collector to verify the debt, use our debt-collector dispute letter. To challenge charges with a hospital, use the provider billing-dispute letter. Those are separate requests, even when they concern the same bill.
Sample letter to dispute medical bills on your credit report
Copy this into a document and replace every bracketed field. Keep only the request that matches your evidence. If you submit online, use the explanation in the portal's dispute field and retain a copy of what you sent.
[Your full name] [Your mailing address] [Date] To: [Credit reporting company and current dispute address] Re: Medical collection entry on report [report number, if available] Reported account: [company name and account number shown on the report] Please investigate the medical collection entry identified above. I dispute [the balance / payment status / ownership of the account / inclusion of this entry] because [explain the specific error or applicable reporting policy]. The report currently shows [what the entry says]. My records show [the correct information, with relevant dates and amounts]. I have attached [list the documents] to support this explanation and highlighted the entry on the enclosed report page. Please [correct the specified information / remove the entry if it should not be included under your medical-collection reporting policy]. Please review the attached evidence and send me the investigation result in writing, along with an updated report if a correction is made. [Your name or signature] [Contact phone number, if needed] Enclosures: [report page and supporting document copies]
A useful explanation names the mismatch: for example, "The account is marked unpaid, but the attached receipt and zero-balance statement show payment in full on [date]." This is example wording, not a customer case. Do not say an account is unfamiliar, paid, or fraudulent unless that is true.
Choose the reason that fits your report
Start with the actual entry, rather than a promise online that every medical collection can be deleted. The CFPB confirms that the 2025 federal medical-debt reporting rule was vacated. Do not cite it as a current nationwide ban in your letter.
- It is not your account: explain the identifying mismatch and request an investigation. For suspected identity theft, follow the recovery process at IdentityTheft.gov.
- The balance or payment status is wrong: state what the report shows and what your payment or billing records show instead.
- The same debt appears twice: identify both entries and explain why you believe they represent one obligation.
- A medical-collection exclusion applies: identify the policy and attach evidence supporting it.
Under the three bureaus' announced policies, medical collections paid in full are excluded, as are those with an initial reported balance under $500. Unpaid medical collections also have a one-year waiting period before appearing. These are reporting policies; exclusion does not itself cancel an unpaid bill.
The under-$500 test concerns the initial reported balance. Paying a larger collection down to $499 is not the same as an account that started below $500. For a timing dispute, ask the reporting company to explain the delinquency date used; the day you first noticed the entry is not the start of the waiting period.
What evidence should you attach?
Make a small, organized packet that lets the reviewer match your explanation to the account. Keep original documents. Use copies and follow the recipient's identity-verification instructions through its official submission channel.
- The report page with the disputed entry highlighted.
- A receipt and paid-in-full statement for a payment-status dispute.
- A corrected provider statement or account ledger for a balance dispute.
- The relevant Explanation of Benefits (EOB), plus the provider's current balance, if insurance processing changed what you owe.
- Previous correspondence and dispute reference numbers, if this is a follow-up.
An EOB is an insurer's explanation, not proof that every provider balance is zero. If the numbers disagree, first use our guide to a medical bill higher than your EOB to identify the mismatch. Leave out unrelated diagnoses, treatment notes, and other people's information. Do not post your dispute packet in public comments or social media.
Where to send your dispute
Send it separately to every bureau whose report contains the issue. Check the current mailing address on your report or the bureau's official website; addresses copied into old templates can change. The CFPB's dispute guide links to all three bureaus' official channels.
Also write to the furnisher: the company named as supplying the entry. That may be a collection agency rather than the hospital. Use its designated credit-report dispute address and explain what it needs to correct with the bureaus. For a mailed dispute, certified mail with a return receipt gives you a delivery record. For an online dispute, save the confirmation.
Keep one folder with the report, your completed letter, attachments, delivery date, and response. A short log makes follow-up easier: "Sent [date]; received [date]; reference [number]; response [date]."
What happens after you send it?
The CFPB explains that a bureau generally has 30 days to investigate, with up to 45 days in some circumstances. It has five business days after completing the investigation to notify you of the result. Count from receipt of the dispute, not the day you started drafting it.
- If corrected or removed: save the result and check that the affected reports reflect it.
- If more information is requested: identify what is missing and provide relevant records through the official channel.
- If the entry is verified but you still disagree: compare the response with your evidence and identify the unresolved fact. A repeated generic letter will not explain what was missed.
For a complaint about inaccurate or incomplete credit-report information, first dispute directly with the bureau. The CFPB's current complaint instructions say to wait until that dispute is no longer pending or more than 45 days have elapsed. Include your original dispute, the response, and the evidence of the remaining error.
If you receive court papers, do not assume this process extends the court's response deadline. Contact a qualified attorney or legal aid promptly.
If the underlying medical bill is wrong
Correcting a credit entry and correcting the provider's bill are different jobs. Ask the billing office for an itemized bill, compare it with your EOB and payments, and request a written explanation of any difference. Keep that work moving while the reporting dispute is reviewed.
If you want help reviewing a supported bill, a mediloop specialist reviews your bill and EOB, if available, and handles supported provider conversations.Pay Per Bill is a flat $129, never a percentage of savings. If the bill is not reduced, or the reduction is less than $129, the fee is refunded in full, the same day. This is help with the medical bill; it is not a promise to remove a credit entry or increase a credit score.
Common questions
Is this the same as a debt-validation letter?
No. This letter challenges information on a credit report. A debt-validation dispute goes to the collector and follows a separate process. Read any collection notice for its response deadline.
Can I dispute a medical bill I already paid?
Yes, if it remains on your report as a medical collection despite payment in full. Include the receipt and a statement confirming the account is paid. Ask for removal under the bureau's medical-collection policy.
Will sending this letter stop collection calls?
Do not assume a credit-bureau dispute pauses collection activity. Address collection notices separately, and keep any billing or court deadlines on your calendar.
Does a dispute guarantee deletion?
No. The company may find the entry accurate and reportable. Use a specific, truthful reason with supporting records. Removal from a credit report also does not automatically mean an unpaid balance has been forgiven.
