What Is NY’s Medical Malpractice Statute of Limitations?

In most cases, the New York medical malpractice statute of limitations gives you two years and six months from the date of the error to file suit.¹ Several exceptions can shift that deadline earlier or later, and a few situations, especially claims against government hospitals or on behalf of children, follow entirely different rules. Miss the deadline and the court will dismiss the case regardless of how strong the evidence is.

The Standard Deadline

Civil Practice Law and Rules Section 214-a sets the deadline for medical, dental, and podiatric malpractice at two years and six months from the negligent act.¹ The clock starts on the day the error happened. If a surgeon makes a mistake during an operation on March 1, 2024, the deadline to file is September 1, 2026.

This is the default rule for adults treated at private doctors’ offices, clinics, and hospitals. Dismissal for missing it is permanent. The claim cannot be refiled, and no later evidence of negligence will revive it.

When the Clock Starts Later

Continuous Treatment by the Same Provider

If the same provider kept treating you for the same condition that gave rise to the malpractice, the two-and-a-half-year clock runs from your last date of treatment rather than from the error itself. A follow-up visit for the original condition counts. An unrelated appointment with the same doctor does not. An exam you requested solely to check on your condition, without receiving actual treatment, also will not extend the deadline.¹

Foreign Objects Left in the Body

When a surgeon leaves a sponge, clamp, or similar instrument inside a patient, the standard deadline often expires before the problem comes to light. New York handles this with a separate one-year rule: you have one year from the date you discover the object, or one year from when you reasonably should have discovered it, whichever is earlier.¹

Not every item left inside the body qualifies. The statute excludes chemical compounds, fixation devices like surgical screws or plates, and prosthetic implants.¹ Those were placed intentionally as part of the procedure, so claims about them fall under the ordinary two-and-a-half-year rule timed from the surgery.

Missed Cancer Diagnoses (Lavern’s Law)

Lavern’s Law created a discovery rule for one specific category of malpractice: a provider’s failure to diagnose cancer or a malignant tumor. You get two and a half years from the date you discovered, or reasonably should have discovered, both the missed diagnosis and the resulting injury.¹ If you were receiving continuous treatment for the same condition, the period runs instead from the last date of treatment. The law uses whichever of those two dates is later.

There is a hard outer boundary. No lawsuit under this rule can be filed more than seven years after the negligent act, regardless of when you learned about it.¹ Lavern’s Law also applies only to cancer and malignant tumors. Missed diagnoses of other serious conditions, such as heart disease or infections, remain subject to the standard rule.

When the Patient Is a Child

When the injured patient is a minor, CPLR Section 208 pauses the statute of limitations during the period of infancy, extending the deadline to three years after the child turns 18.² That full extension rarely applies, however, because an absolute cap controls: the lawsuit must be filed within 10 years of the date the malpractice occurred, even if the child is still a minor.

This cap matters most for birth injuries. If a doctor’s negligence during delivery harmed a newborn, the 10-year window runs from the date of birth, meaning the family must file before the child turns 10. Many families assume they have until the child reaches adulthood to decide. They do not.

When Malpractice Causes Death

If medical malpractice kills a patient, surviving family faces a different and often shorter deadline. A wrongful death lawsuit must be filed within two years of the date of death.³ The clock runs from the date the person died, not the date of the error. If a surgical mistake happened in January 2024 but the patient died in August 2024, the family has until August 2026 to file.

This is a separate claim from the one the patient could have brought while alive. A personal representative of the estate must bring the action, and the damages cover losses to the survivors, such as lost financial support and funeral expenses.

Claims Against Government Hospitals

Suing a government-run facility in New York involves shorter deadlines and extra procedural steps that do not apply to private providers. The rules depend on which level of government runs the facility.

City and County Hospitals

Before suing a city, county, or other local government healthcare facility, you must serve a formal notice of claim on the municipality within 90 days of the incident.⁴ The lawsuit itself must then be filed within one year and 90 days of the malpractice. If the malpractice caused a wrongful death, the lawsuit deadline is two years from the date of death.⁵

The 90-day notice requirement is where most government malpractice claims fall apart. Patients often do not realize they were treated at a public facility, or they do not learn about the notice rule until the window has already closed. Courts can grant permission to file late in limited circumstances, but it is not guaranteed.

State-Run Facilities

Claims against the State of New York itself, including malpractice at a state psychiatric facility or state university hospital, go through the Court of Claims rather than ordinary civil court. The patient must file either a claim or a notice of intention with the Attorney General within 90 days of accrual. Filing a timely notice of intention buys additional time: the claim itself can then be filed within two years.⁶ Without that notice, you have only the same 90 days to file the full claim.

VA and Other Federal Facilities

Malpractice at a VA hospital or other federal healthcare facility falls under the Federal Tort Claims Act, not New York law. You must first file a written administrative claim with the appropriate federal agency within two years of when the claim accrues. Only after the agency denies the claim, or fails to act on it for six months, can you sue. Once the agency sends a written denial, you have six months to file in federal court.⁷ Skipping the administrative claim and going straight to court will get the case dismissed.

Other Situations That Pause the Clock

Active military service stops the clock. Both New York Military Law and the federal Servicemembers Civil Relief Act exclude periods of active duty from the calculation of filing deadlines.⁸⁹ Time spent on active duty does not count toward the deadline, and the remaining time picks up where it left off once service ends.

Mental incapacity works much like the infancy toll. Under CPLR 208, a person who lacks the mental capacity to bring a lawsuit gets the same extension that minors receive, subject to the same 10-year cap from the date of the malpractice.² A patient left with severe brain damage who cannot manage their own affairs would have up to 10 years from the injury, but no longer.

Fraudulent concealment can block a provider from relying on the deadline at all. New York courts have held that a physician who intentionally conceals malpractice from a patient may be estopped from raising the statute of limitations as a defense. The patient must show the concealment was deliberate, not just that the doctor failed to volunteer information about a mistake. It is a difficult argument to win.

Filing on Time Isn’t the Only Requirement

New York also requires that your attorney file a certificate of merit with the initial complaint. Under CPLR 3012-a, the attorney must certify that they reviewed the facts and consulted with at least one licensed physician, dentist, or podiatrist knowledgeable in the relevant area, and that based on that consultation the case has a reasonable basis.¹⁰

Lining up that expert consultation takes time. If the deadline is about to run and the consultation is not finished, the law allows a modified certificate explaining why, with the consultation to follow within 90 days.¹⁰ Treating that as a plan rather than a safety net is risky. The practical lesson is to contact an attorney well before the two-and-a-half-year mark, not in the final weeks.
