New York Medical Malpractice Deadlines

 

Where New York's 30-Month Clock Actually Starts

CPLR § 214-a requires a medical, dental, or podiatric malpractice action to be commenced within two years and six months "of the act, omission or failure complained of or last treatment where there is continuous treatment for the same illness, injury or condition."^[1]

Read that carefully, because it contains the whole problem and most of the solution.

• The default start date is the error itself. Not the diagnosis of the harm. Not the day another doctor told you what happened. New York generally has no broad discovery rule for malpractice, which is unusual and which is exactly why patients lose claims they never knew they had.
• The alternative start date is the last treatment. Where you kept treating with the same provider for the same condition, the clock runs from that final visit instead. For a patient managed over years, that difference is the case.
• Thirty months is not three years. The six-month gap between the malpractice deadline and New York's ordinary injury deadline catches people who looked up "New York statute of limitations" and found the three-year answer.
• The claim must be commenced, not merely asserted. Sending records requests, filing a complaint with the health department, or negotiating with a hospital's risk management office does nothing to the deadline.
• It reaches more than a botched procedure. A claim for lack of informed consent under Public Health Law § 2805-d is a malpractice claim, so it runs on this same 30-month period rather than the ordinary three years.

Continuous Treatment: Why "Too Late" Is Usually Premature

The continuous treatment doctrine is the most frequently misunderstood rule in New York malpractice law, and the one that saves the most claims.

If you continued to receive treatment from the same physician or practice for the same illness, injury, or condition that the negligence involved, the 30 months runs from the last date of that treatment. A surgical error in March 2023 followed by two years of follow-up care with the same surgeon does not become time-barred in September 2025. The clock starts when the treatment relationship for that condition ends.

The doctrine has limits worth knowing before relying on it:

• The continuing care must be for the same condition, not just with the same doctor. Annual physicals with the physician who missed something do not extend the clock.
• The statute expressly excludes examinations undertaken at the patient's request for the sole purpose of ascertaining the state of the patient's condition. Going back to ask "did you get this wrong?" is not continuing treatment.
• Treatment by a different, unaffiliated provider generally does not count, though care within the same practice or hospital group often does.
• Where a course of treatment is planned and ongoing, gaps between visits usually do not break continuity.

Whether the doctrine applies is a chart question, not a calendar question. It is answered by reading the records, which is a free exercise for the patient and a routine one for a malpractice lawyer. We go further into what continuing care qualifies and what New York courts refuse to count on its own page.

Most people who call us convinced they are too late have not had anyone read the chart. Sometimes they are right. Sometimes they aren't. Often the last date of treatment moves the deadline further than they think. We will tell you plainly if the window has closed. We need to look at the records to know.

Lavern's Law and the Missed Cancer Diagnosis

New York's harshest outcome used to be the cancer patient whose claim expired before the cancer was found. That changed with the 2018 amendment known as Lavern's Law, named for a New York City mother whose treatable cancer went undiagnosed after imaging at a public hospital and who learned of it only after the deadline had passed.

CPLR § 214-a(b) now provides that where the claim is based on the alleged negligent failure to diagnose cancer or a malignant tumor, the action may be commenced within two years and six months of the later of:

• when the patient knows or reasonably should have known of the negligent act or omission, and knows or reasonably should have known that it caused injury, subject to an outer limit of seven years from the negligent act; or
• the date of the last treatment where there is continuous treatment for that condition.

Two constraints matter. The rule reaches failure to diagnose cancer or a malignant tumor, not misdiagnosis generally, so a missed heart attack or a missed infection does not get this discovery rule. And the seven-year ceiling is firm; a cancer discovered eight years after a misread scan is outside it.

Our page on delayed cancer diagnosis claims in New York covers how the miss usually happens, how stage shift is proven, and what these cases are worth. Where the missed condition was not cancer, see missed heart attack, stroke, and sepsis claims, which run on the ordinary clock.

The Foreign Object Rule

When a surgical sponge, clamp, or instrument is left inside a patient, CPLR § 214-a(a) allows the action to be commenced within one year of the date the object is discovered, or of the date facts were learned that would reasonably lead to its discovery, whichever is earlier.

This is a genuine discovery rule, and it exists because these cases are close to indefensible on liability. The statute excludes chemical compounds, fixation devices, and prosthetic aids from the definition of a foreign object, so a retained instrument qualifies while a device left in place intentionally does not. One year is a short window, and it starts running the moment the object shows up on an imaging study.

Where that line falls is litigated hard, and the Court of Appeals settled part of it in 2015. See what New York counts as a foreign object and what a hospital will argue is not.

 

Children, Infancy, and the Ten-Year Ceiling

CPLR § 208 tolls the limitations period while a patient is under 18, but malpractice is treated differently from every other kind of injury claim.^[2]

• The general toll. For an infant plaintiff, the deadline is extended to three years after the disability ends, meaning three years after the eighteenth birthday.
• The malpractice ceiling. That extension cannot push a medical, dental, or podiatric malpractice claim beyond 10 years from the date the cause of action accrued. A birth injury discovered when a child is 12 is already outside the window.
• The contrast. The 10-year cap does not apply to a child's ordinary injury claim. A child hurt by a defective product or a negligent driver keeps the full toll to 18 plus three years.
• Public hospitals do not wait. A birth injury at a municipal hospital still carries the 90-day notice of claim requirement, and courts do not treat a parent's lack of knowledge as an automatic excuse.

Families with an injured child usually assume there is time. In New York malpractice, there is less than they think, and the shortest clocks apply to exactly the hospitals where many of these injuries happen.

 

Malpractice at a New York City Public Hospital: 90 Days, Not 30 Months

New York City Health + Hospitals runs the municipal system: Bellevue, Kings County, Elmhurst, Jacobi, Lincoln, Metropolitan, and more. A large share of New York City medical care happens inside it.

Malpractice at one of those facilities is a claim against a public corporation, which means General Municipal Law § 50-e applies. A sworn notice of claim must be served within 90 days of when the claim arises, and the lawsuit must follow within one year and 90 days.^[3]

• Patients almost never know. Nothing about the treatment experience signals that a different, much shorter deadline is running.
• The notice has formal requirements. It must be in writing, sworn to, and state the nature of the claim, the time, place, and manner in which it arose, and the damages claimed. A defective notice can be treated as no notice.
• Late notice is discretionary, not automatic. A court can permit a late notice of claim, but the application has to be made promptly and the outcome is never assured.
• A hearing usually follows. The entity can demand a sworn examination of the claimant under GML § 50-h before suit, which is a real proceeding and not a formality.

If the care in question happened at a city hospital, that fact alone should move the timeline of your entire decision. Our page on the 90-day deadline for a claim against the City covers the mechanics in full.

What Waiting Costs, Beyond the Deadline

Records get harder to assemble. A serious malpractice case can require records from a half dozen providers across several years, and each one has its own release process and its own pace. That collection alone can take months before an expert has anything to review.

New York requires an expert before you file. A physician has to review the chart and support the claim. Finding the right specialist, getting a genuine review, and having it done properly is not a two-week exercise.

Memories and staff turn over. Nurses, residents, and technicians move on. The people who can explain what happened in a room are far easier to identify while they still work there.

The honest answer runs both ways. Sometimes the records show a bad outcome that no reasonable care could have prevented, and a patient deserves to hear that plainly rather than after two years of hope. Either way, the reading has to happen while there is still time to act on it.
