Medical Malpractice Laws in Kentucky (2026): Deadlines & Caps

Medical malpractice in Kentucky is a claim that a physician, hospital, nurse, or other health care provider failed to meet the accepted standard of care and injured a patient. Kentucky has one of the shortest filing windows in the country, but it is also one of the few states whose constitution bars the legislature from capping damages. This page explains the one-year deadline and its discovery rule, why there is no damage cap, the certificate-of-merit requirement, and why Kentucky has no mandatory pre-suit medical review panel. It is general legal information, not legal advice.

Statute of Limitations: One Year, With a Discovery Rule

Kentucky requires medical malpractice actions to be filed within one year under KRS 413.140(1). Claims against physicians, surgeons, dentists, and hospitals fall within this one-year period, making Kentucky one of the strictest states in the nation on timing.

KRS 413.140(2) supplies the discovery rule for those claims. By its terms it applies to the actions listed in KRS 413.140(1)(e), meaning claims against a physician, surgeon, dentist, or hospital. The cause of action is deemed to accrue when the injury is first discovered or, in the exercise of reasonable care, should have been discovered. Because the trigger date can be disputed, anyone who suspects malpractice should consult a licensed Kentucky attorney quickly rather than assume a full year remains.

No Statute of Repose After McCollum

KRS 413.140(2) still contains a five-year outer limit on its face. The subsection closes with a proviso that such action "shall be commenced within five (5) years from the date on which the alleged negligent act or omission is said to have occurred," and that language remains in the current codified text. The Kentucky Supreme Court held the proviso unconstitutional in McCollum v. Sisters of Charity (1990), reasoning that it could destroy a cause of action before the patient ever knew it existed. The General Assembly has never repealed the sentence, so a reader who pulls up the statute today will still see it even though it is unenforceable.

The court grounded its decision in Sections 14, 54, and 241 of the Kentucky Constitution, which protect the right to a remedy and bar the legislature from abolishing common-law claims for personal injury or wrongful death. As a result, Kentucky effectively has no fixed statute of repose for medical malpractice.

Damage Caps: None, by Constitutional Design

Kentucky does not cap medical malpractice damages, and this is not just a legislative choice. Section 54 of the Kentucky Constitution states that the General Assembly shall have no power to limit the amount to be recovered for injuries resulting in death, or for injuries to person or property. Section 241 separately protects recovery for wrongful death.

The Kentucky Supreme Court has enforced these provisions repeatedly through the jural rights doctrine, which reads Sections 14, 54, and 241 together to bar the legislature from abolishing or curtailing common-law recovery for personal injury and death. In Williams v. Wilson (1998), for example, the court struck down the statutory punitive-damages standard in KRS 411.184(1)(c), which had required proof that the defendant acted with flagrant indifference and with a subjective awareness that the conduct would result in death or bodily harm, because that standard destroyed the common-law route to punitive damages for gross negligence. That statute set a standard of proof rather than a dollar ceiling, but it was invalidated under the same constitutional limit that keeps the General Assembly from capping malpractice damages. Because of these constitutional guarantees, Kentucky juries may award economic and noneconomic damages without a statutory ceiling.

Certificate of Merit Required at Filing

While Kentucky has no damage cap, it does impose a screening requirement at the courthouse door. Under KRS 411.167, a plaintiff must file a certificate of merit with the complaint. The certificate is an affidavit or declaration that the claimant has reviewed the facts and consulted at least one qualified expert who believes there is a reasonable basis for the claim.

Limited exceptions exist, including where no expert testimony is needed (such as a retained-sponge case), where three good-faith attempts to obtain a consultation failed, or where the limitations deadline forces a short extension. The Kentucky Supreme Court has required strict compliance: in 2024 and 2025 decisions it confirmed that failing to file the certificate can be fatal to a claim, and it left the statute intact.

No Mandatory Pre-Suit Review Panel

Kentucky briefly required claimants to pass through a medical review panel before suing, but that law is no longer in effect. In Commonwealth v. Claycomb (2018), the Kentucky Supreme Court unanimously struck the Medical Review Panel Act (KRS Chapter 216C) as unconstitutional.

The court held that forcing patients to wait up to nine months for a panel opinion before filing suit delayed access to the courts in violation of Section 14 of the Kentucky Constitution. As a result, there is no mandatory pre-suit review panel in Kentucky today.

Standard of Care, Liable Parties, and Expert Testimony

A Kentucky plaintiff must prove that the provider breached the applicable standard of care and that the breach caused the injury. Doctors, nurses, hospitals, and other licensed providers can all be liable, and hospitals may answer for their own negligence or that of their staff.

Expert testimony is generally required to establish both the standard of care and causation, which is part of why the certificate of merit confirms an expert consultation up front. The rare exception is conduct so obviously negligent that a layperson could recognize it without expert help.

Comparative Fault in Kentucky

Kentucky follows pure comparative fault. The Kentucky Supreme Court adopted the rule in Hilen v. Hays (1984), and the legislature codified it in KRS 411.182. A patient who is partly at fault can still recover, with the award reduced by the patient's percentage of fault, even if that percentage is high.

Wrongful-Death Medical Malpractice

When alleged malpractice causes death, the claim is brought by the estate's personal representative under Kentucky's wrongful-death statute. The deadline is tied to appointment of that representative under KRS 413.180: if a representative is appointed within one year of death, suit must be filed within one year of appointment, and Kentucky courts have generally read the outer limit as two years from the death. Because these timing rules are technical, prompt legal advice is important.

How to Evaluate and Preserve a Possible Claim

Given Kentucky's one-year deadline and certificate-of-merit rule, time is critical. Request complete medical records early and document the timeline of treatment and symptoms while events are fresh, because an expert will need to review the file before a certificate can be filed.

Many Kentucky medical malpractice attorneys offer a free initial consultation and handle cases on a contingency fee, charging only if the case recovers money. No attorney can guarantee an outcome or a specific dollar amount; the value of a case depends on its facts, the evidence, and how a court applies the law.
