The Medical Malpractice Statute of Limitations and the Discovery Rule

Two Clocks Run on Every Malpractice Claim, and Only One Can Bend

Every medical malpractice claim runs against two different deadlines at once.

The statute of limitations, usually one to three years, can start late when you could not have discovered the injury.

The statute of repose cannot. It kills the claim a fixed number of years after the negligent act, in some states even if you never had a chance to know.

Which clock controls, and which exceptions apply, is decided by your state and sometimes by your diagnosis.

People lose winnable cases to this math every year, often by weeks.

The Discovery Rule: When the Clock Starts on a Hidden Injury

The discovery rule answers an unfairness the original limitations statutes created: a patient cannot sue over an injury nobody could have found yet. Where it applies, the limitations period runs from when the patient discovered, or with reasonable diligence should have discovered, the injury and its cause, rather than from the day of the negligent care.

The trap inside the rule is what counts as discovery. The Supreme Court drew the controlling line in United States v. Kubrick: the clock starts when you know of the injury and its cause, not at the later moment you learn the care may have been negligent.^[1] A patient who knows the surgery caused the nerve damage is on the clock, even while every doctor is assuring the family it was an accepted complication.

States codify the rule differently. Tennessee grants one year from discovery when the injury was not found within the ordinary year. Florida runs two years from when the incident was or should have been discovered, inside a four-year outer limit. A few states apply no discovery rule at all to ordinary malpractice claims, which is why the safest assumption is always the earliest plausible start date.

Statutes of Repose: The Outer Deadline That Runs While You Do Not Know

A statute of repose is a different animal. It extinguishes the claim a fixed number of years after the act itself, regardless of discovery. Courts describe the difference bluntly: limitations bars the remedy, repose takes away the right.

Texas is the hard example. Its ten-year repose was upheld in a case where a surgical sponge was discovered eleven years after the hysterectomy that left it behind; the claim was extinguished before the patient ever felt the first symptom.^[2] Georgia's repose runs five years from the act, North Carolina's four, and the malpractice claim dies at the boundary even where the discovery rule would otherwise have saved it.

Repose periods are also why waiting to investigate is the most expensive mistake in this area of law. A diagnosis that surfaces in year four of a five-year repose state leaves months, not years, to obtain records, complete the expert review, and clear the presuit gate.

Continuous Treatment, Foreign Objects, and New York's Cancer Exception

Continuous Treatment

New York's 2.5-year malpractice period runs from the last treatment where there is continuous treatment for the same condition that produced the malpractice, a doctrine codified at CPLR 214-a.^[3] The logic is humane: a patient should not have to sue the physician still treating them. The boundaries are strict, though; checkup visits requested only to monitor the condition do not extend the chain.

Foreign Objects

Most states carve out retained surgical items. New York allows one year from discovery of the object, Georgia one year from discovery even beyond its five-year repose, Tennessee one year from actual or constructive discovery, North Carolina one year capped at ten. Texas, again, allows nothing: its repose has no foreign-object escape, which its own supreme court confirmed in the eleven-year sponge case above.

Lavern's Law

New York adds a diagnosis-specific exception: for negligent failure to diagnose cancer or a malignant tumor, the 2.5 years run from when the patient knew or should have known of the negligent act and the injury, capped at seven years from the act. It is named for Lavern Wilkinson, whose treatable lung cancer appeared on an X-ray nobody told her about.

Children's Malpractice Deadlines Run Shorter Than Parents Assume

The instinct that a child's claim safely waits until adulthood is wrong in most states, because malpractice statutes carve back the ordinary infancy tolling:

• Georgia: a child injured before age five has until the seventh birthday for the limitations period, and no suit after the tenth birthday under the minors' repose. An injury at birth can expire while the child is in fourth grade.^[4]
• New York: infancy tolls the clock, but never more than ten years from the act in malpractice cases.
• Florida: the repose will not bar a claim brought before the child's eighth birthday, a saving clause that still leaves birth-injury families far less time than a childhood.
• Texas: the statute's age-14 rule for minors has been held unconstitutional, so a minor's own claim can run from the eighteenth birthday, but the ten-year repose still binds children. A newborn injured at delivery can lose the claim around age ten.

Birth-injury families face this math most brutally, and the dedicated page on birth injury filing deadlines covers the state patterns in depth.

Concealment, Death, and the Deadlines That Move When Providers Hide Facts

Fraudulent concealment tolls the clock in most states: Georgia runs limitations from discovery of the fraud when the defendant's deception kept the patient from suing, Tennessee opens one year from discovery even past its repose where concealment is shown, and Florida stretches its window to as much as seven years for fraud or intentional misrepresentation.^[5] Concealment usually gets proven from the chart itself, and electronic audit trails have made after-the-fact edits far harder to hide.

Death changes the calendar again, and the direction varies. Georgia starts a fresh two-year period at a malpractice death, inside the unmoved repose. New York gives the estate two years from death, but only if the malpractice claim was still alive when the patient died. Texas runs the malpractice deadline from the negligent act, not the funeral. A family relying on the death date in the wrong state can lose everything by months.

All of it lands on one practical instruction: treat the earliest deadline as the real one. Your state's baseline numbers are in our fifty-state injury deadline table, and the presuit expert machinery that consumes the tail of every malpractice window is mapped on the merit-requirement table.
