Sending a medical bill to collections is not illegal. A healthcare provider can transfer or sell an unpaid account to a third-party collection agency, and no federal law prohibits it. What federal law does control is how the collector can pursue you, what medical information it can see, and how the debt shows up on your credit report. Those protections are real, but most of them apply after the bill has already reached a collector, so the sooner you act on an unpaid medical bill, the more room you have to work with.
When an Unpaid Bill Actually Goes to Collections
Providers rarely send a bill to an outside agency the moment a payment is missed. The billing department usually sends statements, then follow-up notices, then a final warning, while any pending insurance claim is worked out in the background. That internal process can run anywhere from 60 to 180 days.
Nonprofit hospitals face a stricter timeline set by federal tax law. A tax-exempt hospital must wait at least 120 days after sending you the first billing statement before it can report the debt to a credit bureau, sell it to a collector, sue you, or garnish your wages. During that window, the hospital has to notify you about its financial assistance program and give you a plain-language summary of how to apply. A hospital that skips these steps risks losing its tax-exempt status, which makes this one of the more enforceable protections on the timeline.
How Medical Debt Shows Up on Your Credit Report
The three major credit bureaus voluntarily changed how they treat medical collections starting in 2022. Paid medical collection accounts no longer appear on credit reports. Unpaid medical collections don’t appear until a full year after the delinquency date, giving you time to sort out billing disputes or insurance. And since early 2023, any medical collection balance under $500 is excluded from credit reports entirely.
In January 2025, the Consumer Financial Protection Bureau finalized a rule that would have gone further and banned all medical debt from credit reports used by lenders. That rule never took effect. In July 2025, a federal court in Texas vacated it, finding that the Fair Credit Reporting Act expressly allows creditors to obtain and use coded medical debt information and that the CFPB lacked authority to override that.
So the current rules are the voluntary bureau policies, not the broader CFPB ban. Unpaid medical collections over $500 that are more than a year old can still appear on your credit report and still factor into lending decisions.
What Collectors Are Not Allowed to Do
Once a third-party collector has your medical bill, the Fair Debt Collection Practices Act governs every contact. Violations give you the right to sue.
Contact Limits
A collector cannot call you before 8:00 a.m. or after 9:00 p.m. in your local time zone unless you’ve given direct permission. Collectors cannot contact you at work if they know your employer prohibits it. If you send a written notice telling the collector to stop contacting you, it has to stop. After that, the only things it can send you are a confirmation that collection efforts are ending or a notice that it intends to take a specific legal action, such as filing a lawsuit.
The Validation Notice
Within five days of first contacting you, the collector must send a written notice stating the amount of the debt, the name of the creditor, and your right to dispute it. If you dispute the debt in writing within 30 days of receiving that notice, the collector has to stop all collection activity until it sends you verification of the debt or a copy of a judgment. Miss the 30 days and the collector can treat the debt as valid.
Prohibited Tactics
The FDCPA bans harassment, false statements, and unfair practices. In medical debt collection, the common violations are:
- Inflating the balance with fees or interest that weren’t authorized in the original agreement or permitted by law.
- Threatening actions the collector has no legal basis to take, such as arrest or seizure of property.
- Calling repeatedly to annoy rather than to communicate about the debt.
- Discussing your debt with family, friends, or coworkers. Collectors can contact other people only to locate you, and even then usually can’t reveal they’re collecting a debt.
What a Collector Can See About Your Medical History
HIPAA lets a provider share protected health information with a collector because debt collection falls within the definition of “payment” activities. But the provider can only share the minimum necessary information to identify you and the debt.
In practice that means your name, contact details, the date of service, the provider’s name, and the amount owed. Detailed medical records, diagnosis codes, treatment notes, and the specific nature of your condition should not be disclosed. If a collector references your diagnosis or medical details on a call, the provider may have shared more than the law allows. You can file a HIPAA complaint with the Department of Health and Human Services.
Bills That Should Never Reach Collections
Surprise Balance Bills
The No Surprises Act, in effect since 2022, blocks certain bills from reaching collections at all. If you have private insurance and receive emergency care, the provider cannot bill you more than your in-network cost-sharing amount, even if the doctor or facility was out of network. The same protection applies to non-emergency care from an out-of-network provider at an in-network facility, the common scenario where an out-of-network anesthesiologist or radiologist treats you during a planned procedure. Out-of-network air ambulance services are also covered.
If a provider sends you a balance bill that violates the No Surprises Act, you are not legally obligated to pay the excess, and it should never reach collections. Any dispute between the provider and your insurer over the remaining balance goes through a federal arbitration process that doesn’t involve you.
Bills That Blew Past a Good Faith Estimate
If you’re uninsured or paying out of pocket, the No Surprises Act requires providers to give you a good faith estimate of expected charges before treatment. If your final bill exceeds the good faith estimate by $400 or more, you can start a patient-provider dispute resolution through the federal portal. Filing costs $25. While the dispute is pending, the provider cannot send the bill to collections or threaten to. If the bill has already gone to collections, the provider must halt collection efforts until the dispute is resolved.
Bills You Qualified to Have Reduced
Every nonprofit hospital in the country is required by federal tax law to maintain a written financial assistance policy covering at least all emergency and medically necessary care. These programs, sometimes called charity care, can reduce your bill significantly or eliminate it depending on your income. The hospital must post its application on its website, provide free paper copies in the emergency room and admissions areas, and give you a separate 30-day written warning before taking aggressive collection action that spells out what it plans to do and confirms financial assistance is available. If you received care at a nonprofit hospital and can’t afford the bill, apply before the account goes to collections. You may still be eligible after it does.
How to Fight a Bill Already in Collections
Send a Written Dispute
The most important step after a collector contacts you is a written dispute within 30 days of the validation notice. Send it by certified mail with return receipt so you have proof of the date. Once the collector receives your dispute, all collection activity has to stop until it sends you documentation verifying the debt is yours and the amount is correct. Medical bills are notoriously error-prone. Duplicate charges, insurance payments that weren’t applied, and charges for services you never received are all common, and validation forces the collector to prove the numbers before it can proceed.
Push the Insurance Angle
A surprising number of medical bills land in collections because of insurance processing failures rather than money the patient actually owes. If your insurer denied a claim or underpaid, you have the right to appeal. For services you’ve already received, the insurer must complete its internal appeal within 60 days. For urgent situations, the decision must come within four business days. If the internal appeal fails, you can request an independent external review within four months of the final denial, at a cost to you of nothing or no more than $25 depending on the insurer’s process.
Negotiate
If the debt is valid and you can’t pay in full, negotiation is realistic. Collection agencies buy medical debt for a fraction of face value, so they can accept less and still profit. Settlements typically run from 30% to 80% of the original balance, with the age of the debt, your financial situation, and whether you can offer a lump sum all affecting the number. Older debts and larger one-time payments usually draw better offers.
Whether you settle or set up a payment plan, get the agreement in writing before you pay anything. The written agreement should state the total amount you’ll pay, confirm that payment satisfies the debt in full, and specify that the collector will update or remove the account with the credit bureaus. Verbal promises from a collector are worth very little.
If a Collector Sues You
Collection agencies can and do file lawsuits over medical debt. If a collector wins a judgment, it gains enforcement tools including wage garnishment, bank account levies, and property liens. Federal law caps wage garnishment for medical debt at the lesser of 25% of your disposable earnings or the amount by which your weekly disposable earnings exceed 30 times the federal minimum wage. Some states set lower caps.
The most common mistake is ignoring the lawsuit. If you don’t respond, the collector gets a default judgment automatically, and you lose any chance to challenge the amount or raise defenses. File a response even if you believe you owe the money. The collector still has to prove the amount is correct and that it has legal standing to collect.
Every state also sets a deadline after which a collector can no longer sue on an unpaid debt. For medical bills, that period typically runs between three and six years and varies by state. Once it expires, the debt still exists and a collector can still ask you to pay, but it cannot use the court to force payment. Be careful about making a partial payment on old debt. In many states, even a small payment restarts the clock and gives the collector a fresh window to sue.
