A medical bill went to collections: what to do first
Check it before you pay, and do not ignore it. A third-party collector must give you a validation notice, and a written dispute sent by the end date on that notice, which falls 30 days after you are assumed to have received it, stops collection until the debt is verified. Use that window to check the bill, the insurance claim and the hospital's financial assistance policy.
A letter from a collection agency about a medical bill produces two reflexes, and both can cost money. One is to pay quickly to make the problem go away. The other is to put the letter in a drawer. The first can mean paying a bill that was wrong, already paid, or should have been covered by insurance or reduced by financial assistance. The second lets a short window for disputing the debt close. Federal regulations set out what a collector must tell you, what it may not do while you sort things out, and how your response is protected, and this guide turns them into a sequence you can follow.
The rules in this guide are from the CFPB's Regulation F (12 CFR part 1006), the Treasury's nonprofit hospital regulation (26 CFR 1.501(r)-6), and the CFPB's own consumer pages, all checked on October 22, 2026. This is general information, not legal advice. State law adds its own protections and deadlines that this guide does not cover, and a legal aid office or a consumer attorney can look at a specific case. How the same debt can appear on a credit report is covered separately in the guide on medical debt and your credit report.
First, sort out who is collecting
The answer changes which rules apply, so it is worth five minutes before anything else. The collector's name and address are on the letter, and the validation notice must also name the creditor the debt is currently owed to.
| Who is contacting you | Do Regulation F's collector rules apply? | What still applies |
|---|---|---|
| A collection agency hired by the hospital, clinic or lab | Yes. A person whose business principally collects debts, or who regularly collects debts owed to another, is a debt collector | Everything in this guide |
| A company that bought the debt | It depends on the buyer. The definition covers a business whose principal purpose is collecting debts, so a debt buyer whose main business is collecting is within it. Read the validation notice to see who it names as the current creditor | Everything in this guide |
| A law firm collecting for the creditor | Generally yes if it regularly collects debts | Everything in this guide |
| The hospital's own billing office, in the hospital's name | The regulation excludes an officer or employee of a creditor collecting for the creditor in the creditor's name | For a nonprofit hospital, the financial assistance and collection rules in 26 CFR 1.501(r)-6; state law; the hospital's own policies |
| The hospital's billing office using a different name, so that a third person appears to be collecting | The regulation's definition of debt collector includes a creditor that, collecting its own debts, uses a name that would indicate a third person is collecting | Everything in this guide |
Source: 12 CFR 1006.2(i)(1) and (2), current eCFR text, checked October 22, 2026. Who counts as a debt collector can turn on facts a letter does not show; if it matters, ask a legal aid office.
That last distinction matters for hospital bills in particular. Many people are told they are "in collections" when the hospital's own billing department has simply sent a past-due notice. In that case the validation notice and the dispute mechanics below may not apply, but the hospital still owes you its financial assistance process if it is a nonprofit, and you should still dispute errors in writing.
What a validation notice must contain
A debt collector must give you validation information, either in the first communication or within five days of it, or orally in the first communication. The regulation lists what the information must include, and it is the checklist for reading the notice you received.
| Item the notice must show (12 CFR 1006.34(c)) | What to look for |
|---|---|
| The collector's name and the mailing address where it accepts disputes | A real address you can write to |
| Your name and mailing address | Correct; a wrong name can mean a wrong person |
| The name of the creditor to whom the debt was owed on the itemization date, and the name of the creditor it is currently owed to | The hospital, clinic or lab you actually used |
| An account number, or a truncated version | Matches a bill you recognize |
| The itemization date, and the amount of the debt on that date | The itemization date is one of five dates: the last statement date, charge-off date, last payment date, transaction date or judgment date |
| An itemization of the current amount reflecting interest, fees, payments and credits since the itemization date | Whether the amount has grown, and why |
| The current amount of the debt | Compare with your explanation of benefits patient balance |
| The date the collector will treat as the end of the validation period, with what happens if you dispute in writing by then, if you ask in writing for the original creditor's name and address, and if you do not dispute | The deadline |
| A statement that more information on consumer protections in debt collection is at www.cfpb.gov/debt-collection | Included for debts tied to consumer financial products or services |
| Tear-off prompts: "I want to dispute the debt because I think: This is not my debt. The amount is wrong. Other," and a prompt to request the original creditor's name and address | Ways to reply on the form itself |
If the first communication was a phone call, the collector can give this information orally, which is a reason to ask it to send the notice in writing and to write down the date. A notice that omits the required items, or arrives with no end date for the validation period, is itself a record that the collector may not be following the rule.
The 30-day window, with a worked date
The regulation defines the validation period as starting on the date the collector provides the validation information and ending 30 days after you receive, or are assumed to receive, it. To work out the end date, the collector may assume you received the information on any date that is at least five days after it was provided, not counting legal public holidays, Saturdays and Sundays. The notice itself must state the date the collector will treat as the end. The dates below are hypothetical.
| Hypothetical step | Date |
|---|---|
| Collector sends the validation notice (Monday) | November 2, 2026 |
| Receipt assumed after five days, not counting weekends or federal holidays (Tuesday, Wednesday, Thursday, Friday and Monday) | November 9, 2026 |
| Validation period ends 30 days after assumed receipt (a Wednesday) | December 9, 2026 |
If you write to dispute on or before the date on your own notice, the regulation says the collector must cease collection of the debt, or the disputed portion, until it sends you either verification of the debt or a copy of a judgment. The same rule applies if you ask in writing for the original creditor's name and address: collection stops until it sends them, if different from the current creditor. If you miss the window, the debt is not automatically valid in law, and the CFPB says you should still ask for the information you need after 30 days. But the notice says the collector will assume the debt is valid unless you contact it, and the pause in collection is a right that only comes with a timely written dispute. Send it early, not on the last day.
Two other points from the regulation. First, the failure to dispute a debt does not constitute a legal admission of liability. Second, the regulation lets a collector treat a dispute as duplicative, and not pause again, if it is substantially the same as an earlier written dispute the collector already answered and adds no new and material information. So one clear, complete dispute is better than several partial ones. During the validation period a collector also must not engage in collection activities or communications that overshadow or are inconsistent with your rights to dispute the debt and to request the original creditor's name and address.
Before you write: check the bill itself
The collector's notice says what it claims. Whether the claim is right depends on records you have. Work through these in order, because each can change what you say in the dispute.
- Match the creditor and date of service. Confirm the notice names a provider you used, for a date you recognize. Medical accounts are often sold or placed in batches, and mistakes in names and dates happen.
- Find the explanation of benefits. If you had insurance, the plan's patient balance is the ceiling for what an in-network provider should bill, as the guide to reading an explanation of benefits explains. A collection amount above that balance, or for a claim never submitted to the plan, is a reason to dispute.
- Request the itemized bill. The itemized bill check covers duplicates, services you did not receive and wrong quantities.
- Check whether you paid. Gather receipts, card statements and payment confirmations. A payment that was never credited is a common cause of a collection.
- Ask about financial assistance. If a nonprofit hospital is the creditor, it must have a financial assistance policy. The next section covers the collection rules that tie to it.
- Consider insurance appeals and prior authorization. A claim denied for a missing authorization or a coverage reason may still be under appeal. Ask the plan for its denial reason in writing, and see the guide to appealing a health insurance denial.
If after this you believe the debt is wrong or you do not recognize it, dispute it. If the debt appears right and you want to deal with it, you can still dispute for verification first, then negotiate, as described below. The reason to dispute in writing even when you think the amount is right is that it buys a pause and a verified amount.
A nonprofit hospital's own collection limits
For a hospital that is a tax-exempt charity, the Treasury regulation 26 CFR 1.501(r)-6 sets collection limits that apply whoever is collecting: the hospital may not begin extraordinary collection actions, a list that includes selling the debt, credit reporting and lawsuits, until it has made reasonable efforts to determine whether you qualify for its financial assistance policy, and a debt buyer or agency acting for it is treated as the hospital. The waiting periods and notice steps are set out once, in the guide on hospital financial assistance and charity care. If a collector appears very early, or you never received the hospital's notices, raise it in writing with the hospital's patient financial services office and ask whether the assistance application period is still open and whether the account can be recalled while your application is reviewed. For-profit hospitals and most separately billing clinicians are outside this rule, so ask each.
What a collector may and may not do while you sort it out
Regulation F sets limits on how collectors contact you. The ones below are the ones that come up most with medical debt.
| Subject | The rule | Where it is |
|---|---|---|
| Call frequency | Presumed compliant at no more than seven calls in seven consecutive days to you about a particular debt, and no call within seven days after a telephone conversation about it; calls above those frequencies are presumed to violate the rule | 1006.14(b)(2) |
| Time of day | No communications at an unusual time or one the collector knows or should know is inconvenient; before 8:00 a.m. and after 9:00 p.m. local time is presumed inconvenient | 1006.6(b)(1) |
| Your workplace | No contact at work if the collector knows or has reason to know your employer prohibits it | 1006.6(b)(3) |
| If you have a lawyer | No direct contact if the collector knows you are represented and can readily find the attorney's name and address, unless the attorney does not respond in a reasonable time or consents | 1006.6(b)(2) |
| Other people | A collector may generally speak only with you, your attorney, a consumer reporting agency, the creditor, the creditor's attorney and its own attorney, with listed exceptions such as obtaining location information or your consent. "Consumer" for these purposes includes a spouse, a parent of a minor, a guardian, and the executor or administrator of a deceased consumer's estate | 1006.6(a), (d) |
| Stopping contact | If you notify the collector in writing that you refuse to pay or want it to cease communication, it must stop, with exceptions such as to confirm it will stop or to notify you of a specific remedy | 1006.6(c) |
| Old debt | A collector must not bring, or threaten to bring, a legal action to collect a time-barred debt | 1006.26(b) |
| Credit reporting | A collector may not furnish information about a debt to a consumer reporting agency until it has spoken to you, or sent a letter or electronic message and waited a reasonable time for notice that it was undeliverable | 1006.30(a) |
Source: 12 CFR 1006.6, 1006.14, 1006.26 and 1006.30, current eCFR text, checked October 22, 2026.
A written request to stop calls can be useful if the calls are the problem, but it has a cost: it may remove the collector's reason to talk to you, which can matter if you want to negotiate. If you want to keep talking, ask for contact by mail or at set times instead. If you believe a collector has broken a rule, the CFPB says you can submit a complaint to it. Keep a log of dates, times, numbers and what was said.
A written dispute: what to put in it
The regulation's model form gives the shape of a dispute: you identify the debt and say why you dispute it, with the choices of "This is not my debt," "The amount is wrong" and "Other." A letter can follow the same logic. This is a template to adapt, not legal advice.
Template: dispute and request for verification
Date. Your name and address. Collector's name and address as given on the notice for disputes. Reference code or account number. Re: debt claimed for [creditor] for services on [date]. I dispute this debt in full [or: in part, the amount of $___] because: [this is not my debt / the amount is wrong because ___ / insurance has not been billed or processed / I applied for financial assistance on ___ / other]. Please stop collection until you send verification of the debt [or a copy of a judgment]. Please also send the name and address of the original creditor. I am sending this within the validation period shown on your notice. Please do not contact me by telephone; write to me at the address above. Sent by certified mail, return receipt requested; copy kept.
The line about telephone contact is optional, since a request to stop contact is a separate choice, and you may prefer to leave it out. Keep a copy of the letter, the mailing receipt and the collector's reply. Do not send original documents. Include only copies of the records that support your point, such as the explanation of benefits or the payment receipt.
After verification: three ways it can go
The debt is verified and correct
Ask the hospital, in writing, whether the account can be recalled for a financial assistance review, and whether a payment plan is available directly from the provider, which is often more flexible than a collector's. The guide to negotiating a hospital bill covers how to propose one. If you pay a collector, get the settlement terms and how the account will be reported in writing before you send money.
The debt is wrong or you do not owe it
Send the documents that show it, in writing, to the collector and to the creditor. If the collector will not stop and you have a written record, the CFPB complaint route is open. A legal aid office can advise on remedies available under federal and state law.
You are sued
Court papers have deadlines, and ignoring them can end with a judgment you did not contest. The CFPB has a consumer page on what to do if a creditor or collector sues you. Read the papers immediately, note the response deadline, and contact legal aid or an attorney promptly. This guide cannot tell you what your state's deadline is, because it varies. Separately, Regulation F bars suing or threatening to sue on a debt that is past its statute of limitations, and the length of that period is set by state law.
Mistakes that make collections worse
- Paying on the phone to "stop the calls." You may pay a wrong or inflated amount, and a verbal payment promise leaves no record of what was agreed.
- Giving a bank account or card number before the notice arrives. The CFPB says to confirm the collector is legitimate before sharing sensitive financial information.
- Missing the end date because the notice sat unopened. Open mail from a collector the day it arrives, and write the end date on a calendar.
- Disputing only by phone. The pause in collection attaches to a written dispute.
- Treating a hospital's own past-due notice as a collection agency letter, or the reverse. Check the name and who the notice says the debt is owed to.
- Not asking for the hospital's financial assistance review first. Assistance can reduce the balance before anyone negotiates it.
Collector questions, short answers
A collector says I owe a medical bill. What should I do first?
Do not pay and do not ignore it. Ask for the validation information the regulation requires, read it against your own records, and if anything is wrong or unknown, dispute it in writing before the date the notice gives as the end of the validation period. The CFPB says to use the first contact to find out about the debt and to respond in writing.
How long do I have to dispute a debt?
The validation period ends 30 days after you receive the validation notice, and the collector may assume you received it at least five days (not counting weekends and federal holidays) after it was sent. The notice must state the end date. A written dispute made on or before that date stops collection of the disputed amount until the collector sends verification or a copy of a judgment.
Does disputing a debt admit that I owe it?
No. Regulation F says that a consumer's failure to dispute the validity of a debt is not a legal admission of liability. Disputing, or asking for verification, keeps your options open.
How often can a collector call me?
Regulation F presumes a collector complies if it places no more than seven calls within seven consecutive days about a particular debt, and none within seven days after a phone conversation about that debt. Calls above those frequencies are presumed to violate the rule. A collector may not call at a time it knows or should know is inconvenient, and before 8:00 a.m. or after 9:00 p.m. is treated as inconvenient unless it knows otherwise.
Can I make a collector stop contacting me?
Yes, in writing. If you tell a debt collector in writing that you refuse to pay or want it to cease further communication, it generally must stop, with limited exceptions such as confirming that it will stop or telling you about a specific remedy like a lawsuit. Stopping the calls does not erase the debt.
Do these rules apply when the hospital itself is collecting?
Often not. Regulation F's definition of debt collector excludes an officer or employee of a creditor collecting debts for the creditor in the creditor's name, though it includes a creditor that collects under another name. A nonprofit hospital is still bound by the tax rules on collection, and state law may add protections.
