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 a discovery rule for negligence in rendering professional services. The one year runs from the date the patient discovers, or in the exercise of reasonable diligence should have discovered, the injury. 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

Kentucky once had a five-year outer limit in KRS 413.140(2) that purported to bar malpractice suits five years after the negligent act regardless of discovery. The Kentucky Supreme Court held that provision 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 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. In Williams v. Wilson (1998), for example, it struck a statutory limit on punitive damages as a violation of Section 54. 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.
