TL;DR: Medical malpractice in New York means a provider departed from the accepted standard of care and that departure caused real harm — a bad outcome alone is not malpractice. The deadline is short: generally 2 years and 6 months from the malpractice (not from when you discovered it), with key exceptions — Lavern's Law runs the clock from discovery for missed cancer diagnoses (with an outer limit), the clock runs from the end of continuous treatment for the same condition, and claims against public hospitals (NYC Health + Hospitals) require a notice of claim in as little as 90 days. New York has no cap on damages, and its malpractice verdicts are among the largest in the country — but these are also the hardest cases to win, so early expert review is essential.
Key takeaways
- Malpractice = departure from the accepted standard of care that caused harm. A bad outcome alone is not malpractice.
- General deadline: 2 years 6 months (CPLR 214-a) from the malpractice, not from discovery.
- Continuous treatment doctrine can extend the deadline while the same provider keeps treating the same condition.
- Lavern's Law runs the clock from discovery for missed cancer diagnoses (with an outer limit).
- Public hospitals (NYC Health + Hospitals, SUNY): 90-day notice of claim required.
- New York has no cap on pain-and-suffering damages in malpractice cases.
- An attorney expert review (CPLR 3012-a certificate) is required before filing — start early.
Roughly one in three Americans report experiencing a medical error in their own care or a family member's. Very few of those events are legally actionable — but the ones that are tend to be among the most serious injury cases in New York. Here's how to tell the difference.
What legally counts as medical malpractice in New York?
Medical malpractice is a provable departure from the accepted standard of care that directly causes injury. Two elements do all the work: departure (what a reasonably prudent provider would have done differently) and causation (the departure — not the underlying disease — caused the harm). A worsened condition, a known surgical risk that materialized after informed consent, or a treatment that simply failed is not malpractice. New York law requires your attorney to certify the case has merit after consulting a physician (CPLR 3012-a) before suing — which is why screening is rigorous.
The strongest categories of New York malpractice cases
| Category | Typical fact pattern |
|---|---|
| Misdiagnosis / delayed diagnosis | Cancer dismissed as something benign; stroke or heart attack sent home from the ER |
| Surgical errors | Wrong site/structure, nerve damage from technique, retained instruments |
| Birth injuries | Delayed C-section, oxygen deprivation (HIE), brachial plexus/Erb's palsy |
| Medication & anesthesia errors | Wrong drug/dose, failure to monitor |
| Failure to treat / discharge errors | Abnormal test results never communicated; premature ER discharge |
Failure-to-diagnose cancer and birth injury cases are historically the highest-value categories because the harm compounds over a lifetime.
New York's malpractice deadlines (shorter than you think)
- General rule: 2 years, 6 months from the act or omission (CPLR 214-a) — not from when you learned of it.
- Lavern's Law exception: for missed cancer or malignant tumor diagnoses, the 2.5 years runs from when you discovered (or should have discovered) the error, with an outer limit of 7 years from the malpractice.
- Continuous treatment: if the same provider kept treating you for the same condition, the clock runs from the last treatment.
- Foreign object left in the body: 1 year from discovery.
- Public hospitals (NYC Health + Hospitals, county facilities): notice of claim within 90 days and suit within 1 year + 90 days.
- Children: the clock is tolled by infancy, but capped at 10 years from the malpractice — and the 90-day rule for public hospitals still demands urgency.
- Wrongful death from malpractice: 2 years from death.
If any of these windows is close, treat the situation as an emergency.
What a New York malpractice case is worth
New York places no statutory cap on malpractice damages — unlike California, Texas, and most states — and its juries have returned some of the largest malpractice verdicts in U.S. history, including a $120 million Westchester verdict in a delayed-stroke-diagnosis case. Realistically: settlements track the permanence of harm (a lifetime-care birth injury is valued differently than a corrected surgical error), and New York caps attorney fees in malpractice on a sliding scale (Judiciary Law § 474-a) so a larger share of big recoveries goes to the client.
Honesty matters here: malpractice defendants win the majority of cases that go to trial, expert costs are heavy, and good firms accept only cases with clear departures and serious damages. That selectivity is exactly why an early, free expert screen is worth doing — it costs nothing and tells you where you stand.
How to know if your situation is worth reviewing
Strong indicators:
- A diagnosis (especially cancer, stroke, heart attack, infection) was missed despite symptoms or abnormal tests, and the delay changed your prognosis
- A surgery injured a structure unrelated to the procedure, or a second surgeon said the first operation was done wrong
- A baby suffered oxygen deprivation, seizures, or required NICU cooling after a difficult delivery
- Test results showing a serious problem were never communicated
- The harm is permanent or life-altering — malpractice economics rarely support minor-injury claims
What to do now
- Request your complete medical records (you have a legal right to them) — records get amended; get them early.
- Write a timeline while memory is fresh: symptoms, visits, what each provider said.
- Keep treating with new providers — both for your health and to document the harm.
- Don't sign anything from the hospital's risk-management or insurance team.
- Get a free case review quickly — the 2.5-year clock (or 90-day public-hospital clock) is running whether or not you've confirmed what went wrong.

Can I sue my doctor for misdiagnosis?
Yes, if a competent physician with the same information would have made the diagnosis and the delay worsened your outcome. Missed cancer, stroke, and heart attack are the most commonly successful misdiagnosis claims.
How long do I have to sue for medical malpractice in New York?
Generally 2.5 years from the malpractice — not its discovery — with exceptions for missed cancer diagnoses (Lavern's Law), continuous treatment, foreign objects, and children. Public hospital claims require a notice of claim in as little as 90 days.
Is a bad surgical outcome automatically malpractice?
No. Known complications disclosed during informed consent are not malpractice. The question is whether the surgeon's technique or decisions fell below the accepted standard.
What does a malpractice lawyer cost in New York?
Nothing upfront. Fees are contingency-based and capped by statute on a sliding scale that decreases as the recovery grows — and the firm typically advances the substantial expert costs.
Can I sue a public hospital like NYC Health + Hospitals?
Yes, but you must file a notice of claim within 90 days and sue within 1 year and 90 days — the most unforgiving deadline in New York malpractice law.
