The short answer: In most New York medical malpractice cases, you have two years and six months from the date of the negligent care, or from the end of continuous treatment for the same condition, to file your lawsuit. Some situations shorten that window dramatically, and a few extend it. If a public hospital was involved, you may have as little as 90 days to take the first required step. Because these deadlines are strict and the exceptions are easy to miscalculate, it is worth speaking with a NYC medical malpractice lawyer as soon as you suspect something went wrong.
New York gives most patients two years and six months to bring a medical malpractice claim. The clock generally begins on the date of the act, omission, or failure that caused the harm. If a surgeon operated on the wrong site, that date is the surgery. If a physician misread a scan, that date is the day the scan was misread.
This deadline is known as the statute of limitations. Once it passes, the court will almost always dismiss the case no matter how strong the underlying evidence is. There is no partial credit for a claim filed a week late. That finality is exactly why the date the clock starts, and the events that pause or shorten it, matter so much.

The starting date is not always the day of the mistake. Under New York's continuous treatment rule, if you kept receiving care from the same provider for the same condition, the two-and-a-half-year period may begin on the date of your last related treatment rather than the date of the original negligence.
Consider a patient who saw the same oncologist for ongoing cancer care. If that physician failed to act on a warning sign at an early visit but continued treating the patient for the same condition for another year, the deadline may run from the final visit in that course of care. This rule exists so patients are not forced to sue a doctor they are still relying on.
There are limits. Routine checkups that you schedule on your own to monitor your general health usually do not count as continuous treatment. A single follow-up visit unrelated to the original problem may not extend the deadline either. Whether a course of care qualifies is a fact-specific question, and it is one our medical malpractice lawyers examine closely when we review medical records.
New York treats surgical foreign objects differently. If a sponge, clamp, surgical needle, or similar object is left inside your body, you have one year from the date you discovered it, or from the date facts emerged that reasonably should have led you to discover it, to file suit. That one-year window can begin years after the operation, because a retained object often goes unnoticed until it causes pain, infection, or an abnormal imaging result.
This exception is narrow. It covers objects with no intended medical purpose left behind after a procedure. It does not cover chemical compounds, fixation devices such as screws or plates, or prosthetic aids that were placed on purpose. Disputes over the deadline in these cases often turn on when a reasonable person would have connected their symptoms to a retained object, which is where detailed medical and imaging records become important.
For years, New York started the malpractice clock on the date of the negligent act even when a patient had no way of knowing a cancer had been missed. A law commonly known as Lavern's Law changed that for cancer and malignant tumor cases.
Under this discovery rule, a patient who alleges that a provider negligently failed to diagnose cancer or a malignant tumor generally has two years and six months from the date they knew, or reasonably should have known, of both the negligence and the resulting injury. This helps patients whose harm surfaces long after a missed diagnosis.
The rule carries an outer limit. A claim cannot be brought more than seven years after the original negligent act or omission, regardless of when the patient discovers it. Because both the discovery date and the seven-year cap can be contested, cancer misdiagnosis timing is one of the areas where an early case review by a medical malpractice lawyer pays off.
Some of the most serious deadline traps involve public and municipal hospitals. Many hospitals in New York City are operated by NYC Health + Hospitals, including facilities such as Bellevue, Elmhurst, Kings County, and Jacobi. Care provided by a county, a public university medical center, or another government body falls into the same category.
When a public hospital is involved, the ordinary two-and-a-half-year deadline is not your first concern. You generally must serve a formal notice of claim within 90 days of the incident. That document tells the government entity the basic facts of your claim. Miss it, and you can lose the right to sue even if years remain on the standard malpractice clock.
After the notice of claim is served, the overall time to file the lawsuit is also compressed. In most cases against a public hospital, you have one year and 90 days from the incident to bring suit. Courts can sometimes grant permission to serve a late notice of claim, but that permission is never guaranteed and must itself be sought within a limited period. Because so much can go wrong in the first three months, patients who suspect malpractice at a public hospital should speak with a medical malpractice lawyer quickly.
The deadline is more forgiving when the patient is a child. New York pauses, or tolls, the statute of limitations during a child's infancy. In practical terms, the clock does not run in the usual way while the patient is under 18, which gives families additional time to act on a child's behalf.
That extra time is not unlimited. For most pediatric medical malpractice claims, the lawsuit must be filed within 10 years of the negligent act, even with the infancy pause applied. The interaction between the infancy toll and the public hospital rules adds further complication, because the short notice of claim requirements can still apply. Families weighing a claim involving a child are well served by having a medical malpractice lawyer map the exact dates early.
When negligent medical care leads to a patient's death, the family may bring a wrongful death claim through the estate. New York generally allows two years from the date of death to file that claim. This deadline runs from the death itself, which may fall on a different date than the underlying negligence.
A wrongful death claim and the malpractice claim behind it involve separate timelines that have to be coordinated. If a public hospital provided the care, the notice of claim rules apply here as well. The personal representative of the estate is usually the person who must bring the claim, and getting the estate properly opened takes time, which is one more reason not to wait.
Even when a deadline sounds comfortably far off, the work behind a medical malpractice case takes time. Records have to be gathered from every provider involved. Independent physicians have to review the care and, in New York, a qualified medical professional generally must certify that the claim has merit before it is filed. Witnesses have to be located while their memories are fresh, and evidence has to be preserved before it is lost or altered.
Waiting also risks a miscalculated date. The rules above interact in ways that are easy to get wrong, and the difference between the standard two-and-a-half-year window and a 90-day public hospital deadline is enormous. When we review a potential claim at Kelner & Kelner, one of the first things our medical malpractice lawyers do is pin down every applicable deadline so nothing is lost to the calendar.
In most cases you have two years and six months from the date of the negligent care, or from the end of continuous treatment for the same condition. Shorter deadlines apply if a public hospital was involved, and different rules apply to foreign objects, cancer misdiagnosis, children, and wrongful death.
If you file after the deadline, the court will almost always dismiss the case, regardless of how strong the evidence is. A narrow set of exceptions can pause or extend the deadline, so it is worth having a medical malpractice lawyer confirm your date before assuming a claim is too late.
Yes. When care is provided by a public or municipal hospital such as a NYC Health + Hospitals facility, you generally must serve a notice of claim within 90 days of the incident and file the lawsuit within one year and 90 days. These deadlines are much shorter than the standard rule.
Not always. Under the continuous treatment rule, the clock can start on the date of your last related treatment with the same provider. For foreign objects and cancer misdiagnosis, the deadline can instead run from when you discovered, or reasonably should have discovered, the problem.
The estate generally has two years from the date of death to bring a wrongful death claim. If the care was provided by a public hospital, the notice of claim rules apply as well, which can shorten the effective timeline.
Often there is more time for a child. New York pauses the statute of limitations during a child's infancy, though most pediatric claims must still be filed within 10 years of the negligent act. A medical malpractice lawyer can calculate the exact deadline for your child's situation.
Deadlines decide cases before the facts are ever heard. If you believe you or a loved one was harmed by negligent medical care in New York City, the safest step is to have the timeline reviewed now rather than later. Our medical malpractice lawyers at Kelner & Kelner handle serious malpractice and personal injury matters in New York, and we can help you understand which deadline applies to your case and what needs to happen next.
