Got a collection letter for a medical bill? What to do first
A medical collection letter is a notice from a debt collector saying a hospital or doctor's bill has been passed to them to collect. Don't pay or agree to anything on the phone yet. How to make the collector prove the debt, get it back to the hospital, and protect your credit.

The short version
- Don't pay, promise to pay, or agree you owe it yet.
- Dispute it in writing before the date on the letter. The collector has to stop until it verifies the debt.
- Call the hospital: check that insurance was billed, and ask about financial assistance.
A letter from a debt collector about a medical bill is stressful, but you have more options than it seems. Medical debts in collections are often wrong, too high, or were never run through insurance or financial assistance. The first rule: don't pay, promise to pay, or agree that you owe it until you've checked.
Step 1: Read the letter for the dispute deadline
Under the federal Fair Debt Collection Practices Act, a third-party debt collector (not the hospital itself) has to send you a validation notice saying how much they claim you owe, who the original creditor is, and the date by which you can dispute. That window is about 30 days from when you receive the notice, and the letter must print the exact date.
Step 2: Dispute it in writing before that date
If you dispute the debt in writing within that window, or ask for the name of the original creditor, the collector has to stop collecting until it sends you verification. Send the dispute by certified mail with a return receipt, or through the collector's online dispute form, and keep a copy.
“I dispute this debt and request validation. Please send the name and address of the original creditor, the dates of service, an itemized statement, and how the amount was calculated, including any insurance payments and adjustments. Until then, please stop collection and do not report this debt to a credit bureau. This letter is not an acknowledgment that I owe this debt.”
A collector can still report a disputed debt, but it has to show that you dispute it.
Step 3: Call the hospital or provider directly
- Ask whether your insurance was billed for the visit, and ask for an itemized bill.
- Ask whether you can still apply for financial assistance. Many hospitals' programs cover accounts already sent to collections.
- If they find an error or approve assistance, ask them to recall the account from the collector and confirm it in writing.
Step 4: Can it hurt your credit?
Under the three big credit bureaus' current policies, medical collections under $500 aren't reported, there's a one-year wait before any medical collection is reported, and paid medical collections are removed. These are voluntary policies and some states go further. Check your reports for free at AnnualCreditReport.com.
What if the collector doesn't follow the rules?
If a collector keeps collecting after your written dispute without sending verification, threatens you, or calls at unreasonable times, you can file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov/complaint and with your state attorney general.
