Most personal injury cases in New York have to be filed within three years. Medical malpractice cases do not get that much time. Under CPLR 214-a, most claims must be filed within two years and six months of the negligent act, or from the end of continuous treatment for the same condition.
That shorter window is only part of what makes these cases harder.
New York also requires an attorney’s certificate of merit before a medical malpractice lawsuit can be filed, confirming that a qualified medical expert has reviewed the case and found a reasonable basis for the claim.
Without that certificate, the case cannot move forward at all.
Because of this, medical malpractice cases require attorney involvement earlier than almost any other type of injury claim.
A lawyer needs time to gather records, consult with a specialist, and prepare that certificate, all before the deadline to file even arrives.

What Exceptions Can Extend the Filing Deadline?
New York’s two-and-a-half-year deadline is not the same in every case. A few statutory exceptions can change when the clock actually starts.
- Continuous treatment. If your doctor continued treating you for the same condition after the alleged error, the deadline generally does not start running until that treatment ends.
- Foreign objects left in the body. A claim based on a retained surgical instrument or other foreign object can generally be brought within one year of discovery, regardless of when the original procedure took place.
- Cancer misdiagnosis, under Lavern’s Law. For a failure to diagnose cancer or a malignant tumor, the two-and-a-half-year clock runs from when the patient discovered, or reasonably should have discovered, the malpractice, up to a hard cap of seven years from the date of the negligent act.
These exceptions are fact-specific, and figuring out which one applies to your situation, if any, is exactly the kind of judgment call that requires an attorney familiar with New York malpractice law rather than a generalist.
What Should You Look for in a Medical Malpractice Lawyer?
Because these cases hinge so heavily on expert medical testimony and technical procedural rules, the right lawyer needs a specific kind of experience.
- Direct medical malpractice litigation experience, including cases involving the specific type of injury or medical specialty at issue in your situation.
- A track record of taking cases to trial, since hospital insurers and defense firms negotiate differently with attorneys known to prepare every case for court.
- Established relationships with medical experts. New York requires expert testimony to establish that a provider’s care fell below the accepted standard, and building those relationships takes years.
- Familiarity with New York’s filing deadlines and exceptions, including continuous treatment, the foreign object rule, and Lavern’s Law.
- Direct attorney involvement, rather than a case that gets handed off to a case manager once retained.
What Questions Should You Ask During a Consultation?
| Question | Why It Matters |
| How many medical malpractice cases have you handled in New York? | These cases require regulatory and procedural knowledge that general injury cases don’t |
| Have you tried malpractice cases to verdict? | Insurers and hospital defense firms negotiate harder against firms with limited trial experience |
| Do you have experience with the specific specialty or injury involved in my case? | Different medical specialties involve different standards of care and different types of experts |
| How do you handle deadlines, expert review, and record collection? | The certificate of merit and expert review process takes time and must happen before filing |
| Will you personally manage my case? | Some firms hand cases off after signing; you want to know who to expect to hear from |
| What is your contingency fee, and who pays case expenses? | Fee and expense structures can vary between firms and should be explained clearly upfront |
What Red Flags Should You Watch for When Hiring a Lawyer?
A few warning signs tend to separate attorneys who are genuinely equipped to handle a malpractice case from those who are not.
- Inability to clearly explain the filing deadline or how it might apply to your specific situation
- No questions asked about continuous treatment or your ongoing relationship with the provider
- Promises or guarantees about what your case is “worth” before any investigation has happened
- No clear explanation of how the firm obtains medical expert support
- Treating a potential cancer misdiagnosis case like an ordinary negligence claim, without mentioning Lavern’s Law
What Are the Key Deadlines in a New York Medical Malpractice Case?
New York’s malpractice deadlines are strict, and missing one can end your right to compensation no matter how strong the underlying case is.
| Deadline | Rule | What It Means |
| 2 years 6 months | CPLR 214-a | General statute of limitations for medical, dental, or podiatric malpractice in New York |
| 2 years 6 months from discovery, capped at 7 years | CPLR 214-a (Lavern’s Law) | Applies specifically to a failure to diagnose cancer or a malignant tumor |
| 1 year from discovery | CPLR 214-a | Applies to claims involving a foreign object left in the body during a procedure |
| 2 years | EPTL 5-4.1 | Statute of limitations for a wrongful death claim arising from malpractice |
| 90 days | General Municipal Law 50-e | Notice of claim deadline if the claim involves a public hospital or municipal provider |
Because the pre-filing expert review and certificate of merit process takes real time, reaching out to a lawyer as soon as you suspect something went wrong, even before you’re sure you have a case, is one of the most important steps you can take.

Who Can Be Held Liable for Medical Malpractice in New York?
Medical malpractice cases do not always end with the doctor who was directly treating you. Hospitals can be independently liable for the errors of their employed staff, inadequate staffing, and systemic failures like poor infection control, and in many cases the hospital carries more insurance coverage than the individual physician involved.
A lawyer experienced in these cases knows to investigate every potentially liable party rather than stopping at the most obvious one, whether that means a nursing malpractice claim against facility staff or a claim against a physician group or medical corporation.
What Types of Medical Malpractice Cases Require This Level of Experience?
Malpractice claims can arise from almost any point of contact with the healthcare system, and the right lawyer should be comfortable with the specific category your situation falls into.
Common categories include surgical errors, medication errors and overdose, emergency room negligence and birth injuries..
Malpractice can also occur within a specific medical specialty, including cardiology, oncology, radiology, and neurology among others.
A failure to diagnose cancer deserves particular attention given the special rules under Lavern’s Law described above.
