Medical Malpractice Deadlines in New York
Medical malpractice cases carry some of the shortest deadlines in New York law, shorter than most people assume, with exceptions that can shrink them to 90 days. This page explains the rules in plain English. It is general information, not legal advice about your case: the only way to know your actual deadline is to have your facts reviewed.
The general rule: two and a half years.
New York generally allows two years and six months to file a medical malpractice lawsuit. The clock starts at the malpractice itself, meaning the misdiagnosis, the surgical error, or the mismanaged treatment, not at the moment you discovered something was wrong. In most cases, not knowing you were injured does not pause the clock. That single fact catches more people than any other rule on this page.
There is one major softening: continuous treatment. If the same doctor or practice kept treating you for the same condition, the period may not begin until that course of treatment ended. Whether it applies is intensely fact-specific, and defendants fight it hard. It is a rule to be evaluated, never assumed.
Exceptions that change the clock.
A foreign object left in the body, such as a clamp, a sponge, or a fragment of an instrument, carries its own rule: one year from the date it was discovered, or from the facts that should have led to its discovery, even if the general period has passed.
For missed cancer diagnoses, New York’s discovery rule lets time run from when you discovered, or reasonably should have discovered, the error, subject to an outer limit of seven years from the malpractice.
For children, the clock is generally paused until age eighteen, but never past ten years from the malpractice itself. And when a patient dies, a wrongful-death claim generally must be brought within two years of the death. That separate deadline is often shorter than families expect.
The 90-day trap: public hospitals.
If the care happened at a city- or state-run facility, including NYC Health + Hospitals locations such as Bellevue, Elmhurst, or Kings County, the rules change completely. A formal notice of claim is generally required within 90 days of the malpractice, and suit within one year and 90 days. Many otherwise strong cases end here, quietly, before anyone realized a deadline existed.
Why the review should start now.
A malpractice case cannot be filed the day you decide to bring one. Records must be requested and reviewed. New York requires a certificate of merit, a sworn statement that a qualified physician has examined the case, before suit is filed. All of that takes months of runway. Waiting until the deadline is close can make a viable case impossible to bring in time.
Consultations are confidential and there is no cost to discuss your matter. See the firm’s work in medical malpractice and wrongful death, ophthalmology malpractice, and cataract surgery cases.
Deadline questions, answered plainly.
What if I only just found out about the mistake?
In most New York medical malpractice cases, the deadline runs from the malpractice itself, not from when you discovered it. The main exceptions: a foreign object left in the body, where you have one year from discovery, and missed cancer diagnoses, where time runs from when you discovered or should have discovered the error. Have your timeline checked rather than assume either way.
Does the clock pause while I keep seeing the same doctor?
It can. Under New York’s continuous-treatment rule, if the same provider kept treating you for the same condition, the two-and-a-half-year period may not begin until that treatment ended. Whether the rule applies is heavily fact-specific and heavily fought over. It should be evaluated, never assumed.
What if it happened at a public hospital?
Claims against city- or state-run facilities, including NYC Health + Hospitals locations such as Bellevue and Elmhurst, generally require a formal notice of claim within 90 days of the malpractice, and a lawsuit within one year and 90 days. This is the single most unforgiving deadline in New York malpractice law.
Is it too late for me?
Possibly not. Continuous treatment, the foreign-object rule, the cancer-discovery rule, and tolling for minors all move deadlines in ways that surprise people. The only way to know is a review of your actual dates. The consultation is confidential and costs nothing.
Find out where your clock stands.
There’s no cost to ask. A short, confidential conversation is enough to find out where you stand.
