My medical bill was sent to collections before my insurance paid. What should I check?

A collection agency has written about a medical bill. As far as you know, your insurance either has not finished with the claim or already paid its part.

A bill in collections is still a medical bill. It can carry exactly the same problems as the original statement, because it usually is the original statement, passed to someone else. The first job is the same as always: find the Explanation of Benefits for that date of service and compare.

What the EOB tells you

• No EOB at all for that date of service: the plan may never have received the claim, or may still be processing it. The balance the collector is asking for may be the provider's full list price, before any plan payment or network discount. A bill that arrives before the EOB covers why that number cannot be checked yet.
• An EOB that shows a smaller patient responsibility than the collector's amount: the same mismatch as a bill higher than the EOB, now with a collector's letterhead on it.
• An EOB showing $0 owed: see EOB says $0 but a bill arrived.

In every case, the question is whether the amount being collected is the amount the plan says is yours.

What the CFPB says to do

The Consumer Financial Protection Bureau's guidance on medical bills sent to collections says to dispute the debt in writing, sending a letter to the collector as soon as possible, which protects your rights under the Fair Debt Collection Practices Act. Under the Fair Credit Reporting Act, credit reporting companies and the businesses that report to them have obligations when you dispute information on your credit report.

A dispute letter does not need to argue anything. It can simply ask the collector to account for the balance against the plan's processing of the claim, and enclose a copy of the EOB if you have one.

Credit reports: what applies today

These are the rules as their own sources state them; check each source for changes before relying on it.

• No federal ban is in effect. The CFPB finalized a rule in January 2025 to keep most medical debt off credit reports. A federal court in the Eastern District of Texas vacated it on July 11, 2025, and the CFPB's own page records that.
• The three nationwide credit bureaus' own policy: Equifax, Experian and TransUnion stopped reporting paid medical collections from July 1, 2022, stopped reporting medical collections with an initial balance under $500 from April 11, 2023, and wait one year before an unpaid medical collection can appear.
• Some states go further. The CFPB suggests your state attorney general's office as one place to ask.

If the bill came from a nonprofit hospital

Nonprofit hospitals must follow federal rules before what the IRS calls extraordinary collection actions, which include selling the debt to another party and reporting it to a credit bureau. Per the IRS, the hospital must make reasonable efforts to find out whether you qualify for financial assistance first, generally may not start those actions for at least 120 days after the first bill after discharge, must give 30 days' written notice before starting one, and must accept assistance applications for at least 240 days from that first bill. Hospital financial assistance explains how to apply.

What not to do

Do not ignore the letter. Disputing in writing keeps your options open; silence does not.

Do not assume the debt is invalid, either. Often the balance is real and simply has not been reduced by the plan's payment yet. The point of comparing it with the EOB is to find out which situation you are in, and to have the paperwork if the numbers disagree.
