The New York medical malpractice statute of limitations generally gives you two years and six months from the date of the alleged malpractice to file a lawsuit.1New York State Senate. New York Civil Practice Law and Rules 214-A – Action for Medical, Dental or Podiatric Malpractice to Be Commenced Within Two Years and Six Months; Exceptions That is the default. Several exceptions can shorten the window to as little as ninety days or extend it by years, depending on what happened, when you found out, and who treated you. Missing the deadline that applies to your case ends the claim regardless of how strong the underlying facts are.
The General Rule and Continuous Treatment
The two-year-and-six-month clock starts on the date of the alleged malpractice. If the malpractice occurred during an ongoing course of treatment for the same condition, the clock instead starts at the end of that treatment.1New York State Senate. New York Civil Practice Law and Rules 214-A – Action for Medical, Dental or Podiatric Malpractice to Be Commenced Within Two Years and Six Months; Exceptions
The continuous treatment rule is narrower than patients usually assume. The treatment has to relate to the same condition that gave rise to the malpractice, and it has to actually be continuous. Routine checkups with the same doctor for unrelated issues will not toll the deadline. Courts have held that the treatment must run without meaningful interruption and involve the same original complaint.
Foreign Objects Left in the Body
If a surgeon leaves a sponge, clamp, or similar foreign object inside your body, you have one year from the date you discover the object, or reasonably should have discovered it, to file suit.1New York State Senate. New York Civil Practice Law and Rules 214-A – Action for Medical, Dental or Podiatric Malpractice to Be Commenced Within Two Years and Six Months; Exceptions The rule exists because retained objects often produce no symptoms until months or years after surgery, long after the standard deadline would have run out.
Cancer Misdiagnosis: Lavern’s Law
Lavern’s Law, enacted in 2018, changed the filing rule for cases involving a failure to diagnose cancer or a malignant tumor. Before the law, the clock started on the date of the misdiagnosis, so patients who did not learn about the error for years could be barred from suing before they knew they had a claim.2New York State Senate. Senate Bill S6800 – Relates to Accrual of Causes of Action for Medical, Dental and Podiatric Malpractice
Under Lavern’s Law, you have two years and six months from the date you knew or reasonably should have known about the failure to diagnose. The overall window is capped at seven years from the original negligent act, no matter when discovery occurred.3The ASCO Post. Lavern’s Law and Its Implications for Oncology The rule applies to cancer and malignant tumor cases. Proposals to extend it to other delayed-diagnosis conditions have been introduced but have not passed.
Claims Involving Minors
New York tolls the statute of limitations for minors, but with a hard limit that catches many families off guard. Under CPLR § 208, the tolling for a child’s medical malpractice claim cannot extend beyond ten years after the cause of action accrued. Medical malpractice claims do not receive the broader infancy exception that applies to other lawsuits.4New York State Senate. New York Civil Practice Law and Rules 208 – Infancy, Insanity A child injured at birth needs to file by age ten, not by age twenty.
Public and Municipal Hospitals: The 90-Day Notice of Claim
If your treatment happened at a public or municipal hospital, a much shorter deadline applies before the two-and-a-half-year clock is even relevant. Under General Municipal Law § 50-e, you must file a written notice of claim with the public entity within ninety days of the date the claim arose. In wrongful death cases, the ninety days run from the appointment of a representative of the deceased person’s estate.5New York State Senate. New York General Municipal Law 50-E – Notice of Claim
The notice must be in writing, sworn to by the claimant, and it must describe the nature of the claim, when and where the incident occurred, and the injuries sustained. Missing the ninety-day window generally bars the entire lawsuit. Courts can grant permission to file a late notice, but that relief is discretionary and far from guaranteed.5New York State Senate. New York General Municipal Law 50-E – Notice of Claim
Filing on Time Is Not Enough: Certificate of Merit
Beating the deadline gets you into court. Staying there requires meeting New York’s early screening rule. Under CPLR § 3012-a, your attorney must file a certificate of merit with the complaint declaring that the attorney reviewed the facts, consulted with at least one licensed physician (or dentist or podiatrist, depending on the claim) who is knowledgeable about the relevant issues, and concluded there is a reasonable basis for the case.6New York State Senate. New York Civil Practice Law and Rules 3012-A – Certificate of Merit in Medical, Dental and Podiatric Malpractice Actions
The statute carves out a few exceptions. If the statute of limitations is about to expire and there was not time to consult a physician, the attorney can file the complaint first and submit the certificate within ninety days. If the attorney made three good-faith attempts to find a consulting physician and none agreed, that also satisfies the requirement. Cases relying entirely on res ipsa loquitur, where the injury speaks for itself (a surgical instrument left inside a patient, for instance), are exempt from the certificate requirement. Patients filing without an attorney are exempt as well.6New York State Senate. New York Civil Practice Law and Rules 3012-A – Certificate of Merit in Medical, Dental and Podiatric Malpractice Actions
Expert Testimony
Expert testimony is effectively mandatory in a New York medical malpractice case. Because whether a provider met the standard of care involves specialized medical knowledge, courts require an expert to explain that standard and identify how the defendant’s conduct deviated from it. The requirement runs through the case from the certificate of merit through trial.
Experts must have specialized knowledge, training, or experience in the relevant field. A cardiologist offering opinions on an orthopedic surgery would face serious challenges to their qualifications. New York still follows the Frye standard for scientific evidence, meaning any scientific methodology an expert relies on must be generally accepted within the relevant professional community.7New York State Unified Court System. New York Guide to Evidence – 7.01 Opinion of Expert Witness Most federal courts apply the Daubert standard, but New York state courts have kept Frye.
What You Can Recover
If your case is filed on time and prevails, New York allows recovery across three categories of damages. The state does not cap most of them, so the potential recovery depends on the severity of the harm rather than a statutory ceiling.
Economic damages cover measurable financial losses: past and future medical bills, lost wages, diminished earning capacity, and the cost of ongoing care. Future losses typically require an expert economist or vocational specialist to project, and courts examine the calculations closely.
Non-economic damages compensate for pain and suffering, emotional distress, and loss of enjoyment of life. New York does not currently cap non-economic damages in medical malpractice cases. A recurring proposal, Senate Bill S1608 in 2025, would impose a $250,000 cap across personal injury actions, which would significantly alter the economics of malpractice cases if it passed.8New York State Senate. New York State Senate Bill 2025-S1608 It has not.
Punitive damages are rare and require evidence of reckless, wanton, or intentional conduct that goes well beyond ordinary negligence. A surgical error during a difficult procedure will not trigger punitive damages. Operating while intoxicated or deliberately falsifying records might. Most malpractice claims do not meet the threshold.
Attorney Fees Are Capped
New York limits contingency fees in medical malpractice cases. Under Judiciary Law § 474-a, the fee follows a sliding scale calculated on the net recovery after deducting expenses for expert testimony and investigation:9New York State Senate. New York Judiciary Law 474-A – Contingent Fees for Attorneys in Claims or Actions for Medical, Dental or Podiatric Malpractice
- 30% of the first $250,000 recovered
- 25% of the next $250,000
- 20% of the next $500,000
- 15% of the next $250,000
- 10% of anything above $1,250,000
On a $2 million recovery, the attorney’s fee under this schedule is roughly $280,000. Hospital liens and insurance reimbursements are not deducted before the fee is calculated.9New York State Senate. New York Judiciary Law 474-A – Contingent Fees for Attorneys in Claims or Actions for Medical, Dental or Podiatric Malpractice
If you think you may have a claim, the safest move is to figure out which deadline applies to your situation quickly, because the shortest one (the ninety-day notice for public hospitals) can expire while you are still gathering records.
