Medical Bill Sent to Collections: What Happens Now and What to Do in the First 30 Days

A letter arrives from a company you have never heard of. It says you owe a hospital money, that the account has been placed with them, and that you should pay now. Maybe the hospital's own bill never reached you. Maybe you were still disputing it.

Can medical bills go to collections? Yes. Providers refer unpaid accounts to collection agencies, or sell them outright, and it can happen while you are still waiting on an insurer or an itemized bill. What that letter does not change: the bill can still be wrong, and you have more rights now than you did before it arrived.

What actually happened

The provider did one of two things. It assigned the account to a collection agency, which collects on the hospital's behalf for a fee, or it sold the debt to a debt buyer, who now owns it. Either way, the collector usually has a spreadsheet line, not your chart. That gap is where most of your leverage lives.

If the hospital is a nonprofit, one more thing should have happened first. Under Section 501(r)(6) of the Internal Revenue Code, a tax-exempt hospital must make reasonable efforts to find out whether you qualify for financial assistance before taking serious collection steps, including selling the debt or reporting it. It cannot take those steps for at least 120 days after the first post-discharge bill, and it must accept a financial-assistance application for at least 240 days.

If the account moved faster than that, that goes on the record with the hospital. BillFighter's Charity Care Application letter asks the hospital for its financial assistance policy and application under Section 501(r) and asks that collection be paused while it is reviewed; a hospital that finds you eligible must take all reasonably available steps to reverse the collection actions it took (a sale of the debt is the one exception), as long as your application arrived within its application period, at least 240 days from the first bill after discharge. Section 501(r) is enforced by the IRS, not by patients in court, so the letter is leverage, not a lawsuit.

What the collector must do

The Fair Debt Collection Practices Act (15 U.S.C. § 1692g) applies to third-party collectors and debt buyers. Within five days of first contacting you, the collector must send a written validation notice. Under Regulation F, that notice has to state the amount, the creditor you currently owe and, if different, the creditor you owed on the itemization date, an itemization of interest, fees, payments, and credits since a stated date, and the date your 30-day window to dispute ends.

If you dispute the debt in writing within that window, the collector must stop collecting until it obtains verification and mails it to you. You can also ask, in writing and within the same window, for the name and address of the original creditor, and collection stops until they mail it to you.

Read the last paragraph again, because it is where a false claim usually gets inserted. The FDCPA gives the collector no deadline to respond. It does not have to reply in 30 days, or ever. What the law does is freeze collection. No calls, no letters, no lawsuit on the debt, until verification has been mailed to you. Silence from the collector means they cannot move. It does not mean the debt disappears.

The first 30 days: what you do

Day 1. Note the date. The validation notice should print the last day of your window. If it does not, count 30 days from when you received it and keep the envelope.

Day 1 to 3. Send the validation request. Do not call. Write. BillFighter's Debt Validation Letter demands verification of the debt, the name and address of the original creditor, an itemized accounting of the amount, and proof that the collector is entitled to collect it. It is free with a BillFighter account, and the letter text never leaves your browser. Print it and send it by certified mail with return receipt.

Same week. Look up the collector. Search the company in our debt collector directory. Each page shows the consumer complaints the CFPB has logged about that company (complaint counts, not findings of wrongdoing) and how to reach it.

Same week. Go back to the provider. This is the step almost everyone skips. See below.

Keep a log. Every call, every letter, every date. If the collector keeps calling after your written dispute, the log is your evidence.

Fight the bill itself, at the same time

Validation stops the collector. It does not fix the bill. If the underlying charge is wrong, you want the provider to correct it, because a corrected balance is what the collector has to work from.

So, in the same week you send the validation request:

1. Get the itemized bill from the provider. BillFighter's Request Itemized Bill letter asks for it, with codes, dates, quantities, and charges, and asks that the account be held; it goes by certified mail with the delivery record. How to get and read an itemized medical bill.
2. Compare it to your EOB. Anything your insurer paid, or denied as not your responsibility, should not be in the collector's number. How to read an EOB.
3. Dispute the errors with the provider. BillFighter's Dispute Letter names each error by code and date and asks for a corrected statement; it goes by certified mail with the delivery record. How to dispute a medical bill.
4. Apply for financial assistance if the hospital is a nonprofit, even now. Under 501(r), a complete application filed within the 240-day window must be processed, and the policy can reduce or erase a balance already in collection. The Charity Care Application letter starts it. How charity care works.
5. Check the statute of limitations. The time limit for a lawsuit runs from as little as two or three years to ten, depending on the state and how the debt is classified — check your state. A collector can still ask you to pay an old debt, but it cannot sue to collect a time-barred one, and a partial payment can restart the clock in some states. Your state's rules, and what zombie debt is.

Send copies of any correction from the provider to the collector, in writing.

Medical debt and your credit report

This section is about your credit file. BillFighter does not dispute credit reports, is not a credit repair service, and nothing on this page involves it. Three facts, current as of September 2, 2026:

There is no federal ban. The CFPB finalized a rule in January 2025 that would have kept medical debt off credit reports. A federal court in Texas vacated that rule on July 11, 2025. It never took effect.

The credit bureaus' own policies still stand. Equifax, Experian, and TransUnion announced them jointly in 2022 and 2023: paid medical collections are removed, medical collections with an initial balance under $500 are not reported, and unpaid medical collections do not appear until one year after the account first went delinquent. These are company policies, not law.

State laws exist, and they are being challenged. At least fifteen states have laws restricting medical debt on credit reports, per the National Consumer Law Center. On August 10, 2026, a federal court in Texas held that a narrower 2019 Texas law covering surprise out-of-network medical debt was preempted by the Fair Credit Reporting Act and could not be enforced (CDIA v. Paxton). The First Circuit read the same preemption question the other way in a Maine case in 2022. Outside Texas, the state laws remain on the books until a court rules on each one.

What you can do about an entry on your own report is a separate fight from the bill, and it is covered, in Medical debt on your credit report in 2026.

What BillFighter does here

BillFighter reads the collection notice and, if you add it, the original bill. It prepares the letters under your name: the Debt Validation Letter asserting your rights under FDCPA § 1692g, the Request Itemized Bill to the provider, and the Dispute Letter naming each error. You read each one, decide whether to send it, and sign it. Mail it yourself or have BillFighter send it by certified mail. On a paid case it tracks your 30-day window and reminds you when your follow-up date comes.

BillFighter reads your documents, prepares the letters that fit, and keeps the case organized. With the Fight Kit, you print and mail the letters. With In Your Corner, BillFighter mails up to two of your approved letters by certified mail and tracks delivery. You review every draft. BillFighter does not call or negotiate with the other side, and it is not a law firm. Free validation letter with a BillFighter account, or check the notice and the bill, free.
