How Long Do You Have to File a Medical Malpractice Lawsuit in New York?

Reviewed by Alexander Karasik, Esq., Personal Injury & Medical Malpractice Attorney | 19+ Years Experience | Last Updated: September 2026

In New York you have 2 years and 6 months (30 months) to file a medical malpractice lawsuit. That 30-month clock usually starts on the date of the negligent act, or on the last day of continuous treatment for the same condition with the provider who caused the harm. Miss it and the court will almost always dismiss your case, no matter how strong it is.

As Alexander Karasik of Karasik Law Group puts it: "Generally, you have 2.5 years from the date of malpractice to file a lawsuit in New York. In some cases, this time is expanded or contracted depending on different circumstances."

The exceptions below can shorten that window to as little as 90 days (public hospitals) or extend it by years (cancer misdiagnosis, foreign objects, injured children). Which one applies to you depends on the facts of your case.

New York Civil Practice Law and Rules Section 214-a sets the medical malpractice deadline at 30 months from the date of the malpractice. It applies to claims against doctors, surgeons, nurses, hospitals, dentists, anesthesiologists, and other healthcare providers.

This is shorter than the 3-year limit for most other personal injury cases in New York. The Legislature set a tighter window specifically for malpractice, so victims have to act faster than in a car accident or slip-and-fall claim. Courts rarely grant extensions, and once the date passes the defendant can have the case thrown out regardless of how clear the negligence was.

Read the sections below for how each line works, then have an attorney confirm your exact date. The difference between the deadline you assume and the one that actually applies can decide whether you have a case at all.

For a standard claim, the 30 months run from the day the negligent act happened, not the day you found out about it. If a surgeon operated on the wrong body part on March 1, 2024, the deadline is generally September 1, 2026.

New York uses a very narrow discovery rule. If a doctor misdiagnosed your cancer in 2023 and you did not learn of it until 2026, you may already be out of time, because the law usually does not extend your deadline just because you did not know. The foreign object and Lavern's Law exceptions below are the main situations where discovery changes the start date. That narrow rule is exactly why you should talk to an attorney the moment you suspect something went wrong.

If you kept getting treatment from the same provider for the same condition tied to the malpractice, the clock may not start until that treatment ends. New York recognizes that patients should not have to sue a doctor while still in that doctor's care, and that ongoing treatment gives the provider a chance to catch and fix the mistake.

The doctrine only applies to treatment for the same condition. Seeing the same doctor afterward for an unrelated problem does not extend your deadline. An attorney reviewing your medical records can pinpoint the last qualifying treatment date.

If a surgeon left a foreign object inside you, such as a sponge, clamp, or instrument, you have one year from the date you discovered it (or reasonably should have) to file. This exception exists because foreign objects can go years without causing symptoms.

It does not cover objects that were intentionally placed and left in, such as implants, stents, or other medical devices. Those follow the standard rule.

For a negligent failure to diagnose cancer or a malignant tumor, Lavern's Law (in effect since 2018, codified at CPLR 214-a) gives you 2.5 years from the date you discovered the misdiagnosis, or reasonably should have, with an absolute cap of 7 years from the negligent act.

The law is named for Lavern Wilkinson, a Brooklyn mother whose lung cancer went undiagnosed until her claim had already expired under the old rule. It applies only to cancer and malignant tumors. A missed heart condition, undiagnosed infection, or delayed neurological diagnosis still follows the standard 30-month rule.

Example: if a Brooklyn doctor missed your cancer in 2021 and you discovered it in 2025, Lavern's Law gives you until 2027 (2.5 years from discovery), as long as you stay inside the 7-year window from the original negligence.

For a minor, the statute of limitations does not begin until the child turns 18, under CPLR 208. But medical malpractice carries an absolute 10-year cap from the date of the malpractice, and that cap almost always controls in birth injury cases.

A newborn injured during delivery must have a suit filed by the child's 10th birthday, not their 20th. For a child injured at age 12, the deadline is age 20.5 (18 plus 2.5 years), because that comes before the 10-year cap. Parents should not wait: records get purged, witnesses move, and the standard of care in effect at the time gets harder to prove as medicine changes.

If a patient was legally incapacitated at the time of the malpractice, New York may toll (pause) the clock during the period of incapacity, with a 10-year total cap. Once the person regains legal capacity, the standard 30-month deadline runs from that date. This is a strict legal standard backed by medical evidence, not a clinical diagnosis on its own.

Many New York hospitals are run by the city, state, or federal government, and those cases carry far shorter deadlines than a claim against a private provider.

Missing any of these government deadlines is usually fatal to the case. If you were treated at a hospital and are not sure who runs it, have an attorney confirm before the 90-day window closes.

When medical negligence causes a death, the wrongful death claim has its own 2-year deadline from the date of death. If the death occurred at a NYC public hospital, the family must also file a Notice of Claim within 90 days and the lawsuit within 1 year and 90 days. State hospital deaths go to the Court of Claims with the 90-day Notice of Intention.

Even with time left on the clock, delay weakens a case. Medical records are not kept forever and imaging studies get overwritten. Nurses and staff remember the details more clearly close to the event. And every New York malpractice case needs a qualified medical expert to review the records before it can be filed, which takes time your attorney needs on the front end, not the last week before the deadline.

Generally 2 years and 6 months (30 months) from the date of the malpractice, or from the last day of continuous treatment for the same condition. Exceptions for foreign objects, cancer misdiagnosis, minors, and government hospitals can shorten or extend that window.

Usually on the date the negligent act occurred, not when you discovered the harm. Continuous treatment with the same provider for the same condition can move the start date to the end of that treatment. Foreign object and cancer misdiagnosis claims start from the date of discovery.

For a standard adult claim, usually no once 30 months have passed. You may still have time if your case involves a foreign object discovered within the past year, a cancer misdiagnosis under Lavern's Law (subject to the 7-year cap), an injured child within the age limits, or legal incapacity. An attorney can confirm whether an exception applies.

Yes. For NYC public hospitals you must file a Notice of Claim within 90 days of the incident, then the lawsuit within 1 year and 90 days. State and federal facilities have their own shortened deadlines and separate filing procedures.

The clock does not start until the child turns 18, but a 10-year cap from the date of the malpractice almost always controls. In most birth injury cases that means filing by the child's 10th birthday, not the 18th.

Two years from the date of death. If the death occurred at a NYC public hospital, you must also file a Notice of Claim within 90 days.
