Negligence vs. Medical Malpractice in New York

Negligence is any failure to act with reasonable care that injures another person. Medical malpractice is a specific type of negligence committed by a licensed healthcare professional—such as a doctor, nurse, or hospital—who departs from the accepted standard of care in their field. The key distinction is the professional context: malpractice requires proof that the provider deviated from what a competent peer would have done under the same circumstances.

Yes. In New York, ordinary negligence claims generally must be filed within three years under CPLR §214. Medical malpractice claims face a shorter window—two and a half years from the act of malpractice or the end of continuous treatment by the same provider, under CPLR §214-a. Missing this deadline almost always bars your claim permanently, so identifying which statute applies is critical.

Under CPLR §§2004 and case law interpreting §214-a, New York requires medical malpractice plaintiffs to file a certificate of merit within 90 days of serving the complaint. The certificate states that the attorney has consulted with at least one licensed physician who believes there is a reasonable basis for the claim. This requirement does not apply to ordinary negligence lawsuits, making it one of the most practical distinctions between the two types of cases.

Sometimes. If the harm stems from administrative failures—such as a slip and fall on hospital property or a security lapse—the claim may be ordinary negligence subject to the three-year statute of limitations. However, if the injury flows from a clinical decision or treatment error, New York courts will typically classify the claim as medical malpractice regardless of how it is labeled, applying the stricter 2.5-year SOL and certificate of merit requirement.
