Reviewed by Laurence P. Banville, Esq.The General Rule: 2 Years and 6 Months
New York’s medical malpractice statute of limitations is set out in CPLR § 214-a. Unlike most personal injury claims, which get 3 years under CPLR § 214, malpractice claims against doctors, nurses, hospitals, and other licensed medical providers must generally be brought within 30 months of the date the negligent act or omission occurred. Miss that window and the court will almost always dismiss the case, no matter how strong the underlying facts are.
The Continuous Treatment Rule
The clock does not always start on the day of the negligent act. Under the continuous treatment doctrine, if you kept seeing the same doctor or facility for the same condition, the 30-month period is tolled and doesn’t begin running until that course of treatment ends. The idea is that a patient shouldn’t have to sue a provider they’re still relying on for care. This rule frequently extends deadlines for patients with ongoing relationships with a surgeon, OB/GYN, or treating specialist — but it requires an actual continuing course of treatment for the same condition, not just periodic checkups.
The Foreign-Object Exception
New York carves out a separate, more generous rule when a surgical instrument, sponge, or other object is negligently left inside a patient’s body. In those cases, the claim must be filed within 1 year of discovery of the object (or when it reasonably should have been discovered), regardless of how much time has passed since the surgery. This exception does not apply to items intentionally left as part of treatment, such as surgical clips or prosthetic devices.
Lavern’s Law: Missed Cancer Diagnoses
Lavern’s Law, enacted in 2018, addresses a gap that existed for negligent failure to diagnose cancer. Under this law, the 30-month clock runs from whichever is later: the date of the malpractice, or the date the patient discovers (or should have discovered) the negligent failure to diagnose — capped at 7 years from the malpractice itself. This matters because a missed or delayed cancer diagnosis often isn’t apparent until well after the original visit, when the disease has progressed.
Public and Municipal Hospitals: A Shorter Deadline
If the malpractice involved a public hospital, municipal facility, or other government-run healthcare provider (such as a NYC Health + Hospitals facility), the timeline is significantly compressed. You generally must serve a Notice of Claim within 90 days of the incident, and the lawsuit itself must typically be filed within 1 year and 90 days of the malpractice. These deadlines run independently of the standard 30-month rule and are strictly enforced, which is why it’s critical to identify early whether a public entity was involved.
The Infancy Toll for Children
When the injured patient is a minor, New York law tolls the statute of limitations until the child turns 18, though the total time to sue after that is capped at 10 years from the date of the malpractice. Claims involving a public hospital have their own modified infancy provisions, so a child’s case against a municipal facility still requires prompt attention rather than waiting until adulthood.
Why the Deadline You Think Applies May Be Wrong
Because so many overlapping rules can apply — continuous treatment, the foreign-object exception, Lavern’s Law, public-hospital notice requirements, and infancy tolling — the actual filing deadline in any given case is rarely a simple date on a calendar. An experienced medical malpractice attorney can review your treatment history and medical records to pinpoint which rule governs your claim and how much time you actually have left.
Frequently asked questions
What is the statute of limitations for medical malpractice in New York?
New York's general medical malpractice statute of limitations is 2 years and 6 months (30 months) from the date of the negligent act or omission, under CPLR 214-a. If the same provider continued treating you for the same condition, the clock may not start until that treatment ends. Several exceptions can shorten or lengthen this deadline depending on the facts.
How long do I have to sue a doctor or hospital in NY?
You generally have 30 months from the malpractice to sue a private doctor, nurse, or hospital in New York. If a public or municipal hospital is involved, the timeline is much shorter: a Notice of Claim within 90 days and a lawsuit within 1 year and 90 days. Because these deadlines run independently, it's important to confirm early whether a government facility treated you.
What is the continuous treatment rule?
The continuous treatment rule tolls the statute of limitations while a patient remains under the ongoing care of the same doctor or facility for the same medical condition. Instead of starting on the date of the negligent act, the 30-month clock begins once that continuous course of treatment ends. It does not apply to unrelated conditions or to sporadic, unconnected visits.
Is the deadline different for a missed cancer diagnosis (Lavern's Law)?
Yes. Lavern's Law lets the 30-month clock start from whichever is later: the date of the negligent failure to diagnose cancer, or the date the patient discovers or reasonably should have discovered that failure. This discovery-based deadline is capped at 7 years from the original malpractice, recognizing that a missed cancer diagnosis often isn't apparent for years.
What happens if a public hospital was involved?
Claims against public or municipal hospitals, such as NYC Health + Hospitals facilities, require a Notice of Claim served within 90 days of the malpractice, followed by a lawsuit generally filed within 1 year and 90 days. These deadlines are strictly enforced and run separately from the standard 30-month rule, so identifying a public defendant early is critical to preserving your case.
