It is not illegal to send medical bills to collections. A healthcare provider can assign or sell an unpaid account to a third-party collection agency, and no federal law prohibits the handoff. What federal law does control is how a collector can pursue you after it takes the account, what parts of your medical history it is allowed to see, and how the debt can appear on your credit report. Those protections are real, but they only start working once the bill is already in collections, so acting early gives you the most room to maneuver.
When a Medical Bill Actually Goes to Collections
Providers rarely transfer a bill to a collection agency the moment a payment is missed. The usual sequence runs through the provider’s own billing department first: statements, follow-up notices, and often a final warning while any pending insurance claim is still being worked. That internal window typically lasts somewhere between 60 and 180 days.1Provider billing timelines before collections
When the provider gives up on resolving the account internally, it either assigns the debt to a collection agency that collects on the provider’s behalf, or sells the debt outright to an agency that paid pennies on the dollar and keeps whatever it recovers. The balance you owe on paper does not change either way.
Nonprofit hospitals are on a slower clock. Under federal tax-exemption rules, a nonprofit hospital must wait at least 120 days after sending the first billing statement before it can report the debt to a credit bureau, sell it, sue you, or garnish wages. During that window, the hospital has to tell you about its financial assistance program and give you a plain-language summary of how to apply.
How Medical Debt Shows Up on Your Credit Report
The three major credit bureaus changed their handling of medical collections starting in 2022. Paid medical collection accounts no longer appear on credit reports. Unpaid medical collections do not appear until a full year after the delinquency date, which gives you time to resolve billing disputes and insurance questions. And since early 2023, any medical collection balance under $500 is excluded from credit reports entirely.
The Consumer Financial Protection Bureau finalized a broader rule in January 2025 that would have 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, holding that the Fair Credit Reporting Act expressly permits creditors to obtain and use coded medical debt information in credit decisions and that the CFPB exceeded its authority by trying to override that.
So the rules that actually bind right now are the voluntary bureau policies, not the vacated CFPB ban. An unpaid medical collection over $500 that is more than a year old can still land on your credit report and still factor into lending decisions.
Your Rights Under the Fair Debt Collection Practices Act
Once a third-party collector holds your medical bill, the Fair Debt Collection Practices Act governs every interaction. Violations give you the right to sue.
Limits on Contact
A collector cannot call you before 8:00 a.m. or after 9:00 p.m. in your local time zone without your 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 comply; after that, the only communications allowed are a confirmation that collection efforts are ending or a notice of specific legal action like 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. If you do not dispute the debt in writing within 30 days of receiving that notice, the collector can treat it as valid. If you do dispute it in writing within the 30 days, the collector must stop all collection activity until it mails you verification of the debt or a copy of a judgment.
Prohibited Tactics
The FDCPA bans harassment, false statements, and unfair practices. The most common violations in medical debt collection involve:
- Inflating the balance with fees or interest that were not authorized in the original agreement or by law.
- Threatening actions the collector has no legal basis to take, such as arrest or seizure of property.
- Repeated calls intended to harass rather than communicate.
- Discussing the debt with family, friends, or coworkers. Collectors can contact other people only to locate you, and usually cannot reveal that they are collecting a debt.
What a Collector Is Allowed to Know About Your Care
HIPAA permits a provider to share protected health information with a collector because debt collection is a “payment” activity. But the provider can only share the minimum necessary to identify you and the debt. In practice that is your name, contact details, the date of service, the provider’s name, and the amount owed. Diagnosis codes, treatment notes, and the specific nature of your condition should not be disclosed.
If a collector references your diagnosis or clinical details on a call, that is a signal the provider may have handed over more than HIPAA allows. You can file a HIPAA complaint with the Department of Health and Human Services.
Bills That Should Never Reach Collections at All
The No Surprises Act, in effect since 2022, prevents several categories of bills from being sent to collections in the first place. 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 the facility was out of network. The same protection applies to non-emergency care from an out-of-network provider at an in-network facility, which is the usual scenario when an out-of-network anesthesiologist or radiologist appears 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 that amount should not reach collections. Any dispute between the provider and your insurer over the balance goes through a federal arbitration process you are not part of.
If you are uninsured or paying out of pocket, you are entitled to a good faith estimate before treatment. When the final bill exceeds that estimate by $400 or more, you can open a patient-provider dispute through the federal portal for a $25 filing fee. While the dispute is pending, the provider cannot send the bill to collections or threaten to, and if it already went to collections, collection efforts have to stop until the dispute is resolved.
Nonprofit Hospital Financial Assistance
Every nonprofit hospital in the country is required by federal tax law to maintain a written financial assistance policy that covers at least all emergency and medically necessary care. Depending on your income, charity care can cut a bill significantly or wipe it out.
The hospital has to make the application available on its website, provide paper copies for free in the emergency room and admissions areas, and notify the community about the program. Before taking aggressive collection action, the hospital must give you at least 120 days from the first billing statement plus a separate 30-day written warning that identifies the collection actions it intends to take, tells you financial assistance is available, and summarizes the application process in plain language.
A nonprofit hospital that reports your bill to a credit bureau, sends it to collections, or sues you without following these steps risks its tax-exempt status. If you cannot afford the bill, apply before the account goes to collections. You may still be eligible after it does.
How to Dispute and Resolve the Debt
Send a Written Validation Request
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. Once the collector receives it, collection activity has to stop until the collector sends documentation showing the debt is yours and the amount is correct. Medical bills are error-prone: duplicate charges, insurance payments that were never applied, and bills for services never received are all common. Validation forces the paperwork onto the table.
Check Whether Insurance Should Have Paid
A surprising share of medical bills reach collections because of insurance processing failures rather than any amount you actually owe. If your insurer denied a claim or underpaid, you have the right to appeal internally. If the internal appeal fails, you can request an independent external review within four months of the final denial, at a cost of nothing or no more than $25 depending on the review process.
Negotiate a Settlement or Payment Plan
If the debt is valid and you cannot pay in full, negotiating is realistic. Collection agencies that bought the debt paid a fraction of the face value, so they can accept less and still profit. Settlements commonly land somewhere between 30% and 80% of the original balance, with older debts and lump-sum offers getting better numbers than fresh accounts and installment plans.
Whether you settle or set up a payment plan, get the agreement in writing before you send a dollar. The written agreement should state the total you will 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.
The Tax Bill That Can Follow a Settlement
If a collector forgives $600 or more through a settlement, the creditor has to report the canceled amount to the IRS on Form 1099-C, and that amount is generally treated as taxable income. Settle a $5,000 debt for $2,000, and the $3,000 difference can appear as income on your return.
There is an important exception. If you were insolvent at the time of the settlement, meaning your total liabilities exceeded the fair market value of your assets, you can exclude the canceled debt from income up to the amount of your insolvency, using IRS Form 982. The financial pressure that pushes someone to settle medical debt often lines up with insolvency, so this exception matters.
If a Collector Sues You
Collection agencies do file lawsuits over medical debt. A judgment unlocks enforcement tools: wage garnishment, bank levies, and property liens. Federal law caps wage garnishment for ordinary debts, including 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 worst thing you can do is ignore the suit. No response means a default judgment, and the chance to challenge the amount or raise defenses is gone. File a response even if you think you owe the money, because the collector still has to prove the balance and its legal standing.
Statute of Limitations
Every state sets a deadline after which a collector can no longer sue over an unpaid debt. For medical bills, the window typically runs between three and six years depending on the state. Once it expires, the debt still exists and the collector can still ask you to pay, but it cannot use the courts to force payment. Be careful with partial payments on old debt. In many states, even a small payment restarts the clock and hands the collector a fresh window to file suit.
