In Kentucky, a medical provider or collector generally has five years to sue you over an unpaid bill if there is no signed payment agreement, and ten years if you signed one. That is the short version of the statute of limitations on medical debt in Kentucky, and the paperwork you signed at check-in is usually what decides which deadline applies. Once the deadline passes, the creditor loses the right to win a lawsuit against you, though the debt itself still exists and collectors can still ask you to pay.
Five Years or Ten Years: Which Deadline Applies
Kentucky has two statutes of limitations that can reach medical debt, and the dividing line is whether a written contract exists.
- Five years under KRS 413.120 for oral or implied contracts. If you received care without signing anything that promised payment, the debt is treated as an implied contract and the creditor has five years from the date the bill became due to file suit.1Kentucky Legislative Research Commission. Kentucky Revised Statutes 413.120 – Actions to Be Brought Within Five Years
- Ten years under KRS 413.160 for written contracts. If you signed a financial responsibility form or any other document agreeing to pay for services, a court can treat the debt as a written contract and apply the ten-year deadline.2Kentucky Legislative Research Commission. Kentucky Revised Statutes 413.160 – Actions Upon Written Contract or Not Provided for by Statute – Ten-Year Limitation
Most hospitals and medical offices have patients sign financial responsibility paperwork during intake, so the ten-year window is often the one that applies. If a collector contacts you about an older bill, ask for a copy of what you signed. A consent-to-treat form that says nothing about payment is different from a financial agreement that promises to pay for services rendered. If the only paperwork is the consent form, or no paperwork exists at all, the five-year deadline is more likely to control.
The clock starts when the cause of action “accrues,” which for a medical bill generally means the date the bill went unpaid past its due date. That is usually a set number of days after the provider sends the first billing statement, not the date of treatment.
What Can Restart or Pause the Clock
The limitations period is not always a straight countdown. A few events can extend it or freeze it, and one of them is a common trap.
Partial Payments and Written Acknowledgment
Making even a small payment on an old medical debt can restart the statute of limitations from the date of that payment. Acknowledging the debt in writing can do the same thing. A collector calls about a seven-year-old hospital bill, you send $25 as a goodwill gesture, and the creditor now has a fresh five-or-ten-year window to take you to court. If a debt is near or past its deadline, think carefully before paying anything or putting anything in writing about it.
Active Military Service
Under the federal Servicemembers Civil Relief Act, time spent on active military duty does not count toward any statute of limitations. If you were called to active duty while a medical debt was outstanding, the clock pauses for the entire period of service and picks up when you return to civilian life.3Office of the Law Revision Counsel. 50 USC Chapter 50 – Servicemembers Civil Relief
Bankruptcy
Filing for bankruptcy triggers an automatic stay that halts all collection activity, including lawsuits. The limitations period is effectively frozen while the stay is in place because the creditor is legally barred from suing. If the bankruptcy case is dismissed without a discharge, the remaining time on the statute of limitations resumes where it left off.
Legal Incapacity
Under KRS 413.170, the statute of limitations does not run while certain legal disabilities exist, such as being a minor or being declared legally incompetent. The clock begins only once the disability ends.
What Happens If a Creditor Sues and Wins
The deadline matters because the consequences of letting a lawsuit slide forward are serious and long-lasting. When a medical creditor files suit within the limitations period and wins, the court enters a judgment, and a judgment is a far more powerful collection tool than an unpaid bill.
A Kentucky judgment remains enforceable for 15 years from the date of the last execution on it.4Kentucky Legislative Research Commission. Kentucky Revised Statutes 413.090 – Action Upon Judgment, Contract, or Bond – Fifteen-Year Limitation It accrues interest at 6% per year, compounded annually, unless the original agreement specified a different rate.5Kentucky Legislative Research Commission. Kentucky Revised Statutes 360.040 – Interest on Judgments On a $10,000 medical judgment, that is roughly $600 in added interest each year.
A judgment creditor can also record a lien against your real property by filing a notice of judgment lien with the county clerk in any Kentucky county where you own land. The lien typically has to be satisfied before you can sell or refinance. Kentucky’s homestead exemption shields a portion of a home’s value from creditors; for the 2025–2026 assessment years, that exemption is $49,100.
Wage Garnishment
With a judgment in hand, a creditor can seek a court order to garnish your wages. Kentucky caps the weekly garnishment at the lesser of 25% of your disposable earnings or the amount by which your disposable earnings exceed 30 times the federal minimum hourly wage.6Kentucky Legislative Research Commission. Kentucky Revised Statutes 427.010 – Exempt Personal Property, Health Savings Funds Disposable earnings are what remains after legally required deductions like taxes and Social Security. At the current federal minimum wage of $7.25, the 30-times threshold is $217.50 per week. If your weekly disposable earnings fall below that, nothing can be garnished.
The Default Judgment Problem
This is why ignoring a medical debt lawsuit is such a costly mistake. If you don’t respond, the court enters a default judgment and the creditor gains access to garnishment and liens without having to prove much of anything beyond that you were properly served. Showing up matters even when you think the debt is too old to sue over, because the court will not raise the statute of limitations on your behalf.
Using the Statute of Limitations as a Defense
The limitations period is what lawyers call an affirmative defense. The creditor can still file the lawsuit after the deadline; the court will not block it automatically. You have to raise the defense yourself, usually in your written answer to the complaint. If you plead it and the deadline has in fact passed, the case can be dismissed.
Before you respond to any lawsuit or old collection notice, pin down three things: when the bill originally became due, whether you signed a written payment agreement, and whether anything has happened since (a payment, a written acknowledgment, military service, a bankruptcy filing) that could have paused or restarted the clock. Those three facts determine whether the statute of limitations is on your side.
Request a copy of any signed paperwork from the original provider or ask the collector to produce it as part of debt validation. Without that document, a creditor claiming the ten-year written-contract period may have trouble proving it is entitled to the longer window.
A Note on Credit Reporting
The right to sue and the right to report a debt to the credit bureaus run on different clocks, and it is easy to confuse them. Under the Fair Credit Reporting Act, unpaid medical debt of $500 or more can remain on your credit report for up to seven years from the date of the original delinquency, and the three major credit bureaus wait one year after delinquency before reporting medical debt at all. Paid medical collections and unpaid medical debt under $500 are kept off credit reports under the bureaus’ voluntary policy. None of that changes how long a creditor has to sue you; a debt can be past Kentucky’s statute of limitations and still appear on your credit report, or be off your credit report and still within the window for a lawsuit.
