See the 60-second demo →New York med-mal practice has four moving parts that distinguish it from neighboring states: a 2.5-year statute of limitations under CPLR 214-a, the continuous treatment doctrine and Lavern's Law cancer-misdiagnosis discovery rule, the CPLR 3012-a certificate of merit, and a Frye reliability standard in a country that has largely moved to Daubert. The damages framework is plaintiff-favorable — no statutory non-economic damages cap, structured judgment rules under CPLR Articles 50-A and 50-B.
This is the 2026 working overview for plaintiff firms running New York med-mal — CPLR 214-a, continuous treatment, Frye, and the case-building posture that decides whether the case survives long enough to reach the substantive damages framework.
CPLR 214-a sets the limitations period for a medical, dental, or podiatric malpractice action at two years and six months from the act, omission, or failure complained of, or last treatment when there is continuous treatment for the same illness, injury, or condition. For minors, CPLR 208 tolls the limitations period until the eighteenth birthday with a 10-year outer limit (extended in some categories).
Three structural features differentiate New York's framework:
Practical implication for case-building: New York's framework rewards record reviews that document the treatment timeline in granular detail. A continuous-treatment defense requires the record to show that the relationship between the patient and the alleged tortfeasor extended past the negligent act for the same condition. A Lavern's Law case requires the record to show when the symptoms presented, when imaging or labs flagged the abnormality, and when the patient was actually informed.
CPLR 3012-a requires the plaintiff in a medical, dental, or podiatric malpractice action to file with the complaint, or within 90 days thereafter, a certificate of merit stating that the attorney has reviewed the facts of the case, has consulted with at least one licensed physician (or dentist or podiatrist) the attorney reasonably believes is knowledgeable in the relevant issues, and concluded on the basis of that consultation that there is a reasonable basis for the commencement of the action.
The CPLR 3012-a certificate is less strict than Florida's Chapter 766 corroborating affidavit. The certifying physician need not be the same specialty as the defendant and need not submit a written affidavit. But the attorney's certification is sworn under penalty of frivolous-litigation sanctions. Bar discipline cases under DR 7-102 / RPC 3.1 have followed from CPLR 3012-a certifications later shown to lack a colorable factual basis.
Practical implication: the certification is real. The "reasonable belief" standard is what is signed by the attorney — and the supporting consultation should be documented in the engagement file. Plaintiff firms that treat CPLR 3012-a as a formality leave themselves exposed when a defense motion later reveals the case was filed without substantive expert support.
New York is one of the few remaining Frye jurisdictions. Frye v. United States, 293 F. 1013 (D.C. Cir. 1923), asks whether the expert's methodology has gained general acceptance in the relevant scientific community. People v. Wesley, 83 N.Y.2d 417 (1994), adopted the test. Parker v. Mobil Oil Corp., 7 N.Y.3d 434 (2006), and Cornell v. 360 W. 51st St. Realty, LLC, 22 N.Y.3d 762 (2014), refined what general acceptance requires — particularly in toxic-tort cases — and have analytical force in med-mal causation cases as well.
The 2026 reality is that New York's Frye framework has converged with federal Daubert in practice, even though the doctrinal labels differ. Defense motions in New York med-mal cases routinely cite Parker's requirement that the expert's specific-causation methodology has to be generally accepted in its application to the case at hand — not merely in its general validity. A causation opinion that combines accepted epidemiological data with accepted differential-diagnosis methodology but applies the combination to a specific case in a way that has not been published or peer-reviewed faces meaningful Frye exposure.
The plaintiff-side response is the same as the federal-court response: methodology articulated in named steps, each step mapped to peer-reviewed literature, differential-diagnosis analysis with ruled-in and ruled-out alternatives, expert qualifications mapped to the defendant's specialty.
New York does not have a statutory cap on non-economic damages in med-mal cases. The damages framework is governed by CPLR Articles 50-A (medical, dental, and podiatric malpractice) and 50-B (general tort) — the structured-judgment rules that convert lump-sum verdicts into periodic payments for future damages above specified thresholds.
The interaction between structured judgment and case economics is non-obvious. A jury verdict for future damages above the threshold is paid out over the plaintiff's life expectancy (with present-value adjustments) rather than in a lump sum. The plaintiff firm's contingency fee is calculated on the present value of the structured stream, not the gross verdict number. Cases that look attractive on gross verdict numbers can be less attractive after Article 50-A is applied.
Practical implication for case selection: New York med-mal cases reward firms that model the structured-judgment outcome at intake, not just the gross damages exposure. A plaintiff firm running New York cases without a structured-judgment-aware damages model is selecting cases on the wrong number.
MedLegal AI's Daubert/Frye workup tool builds plaintiff expert reports to the New York standard: methodology mapped to peer-reviewed literature with general-acceptance documentation, alternative-cause analysis ruled in and ruled out with record citations, expert qualifications mapped to the defendant's specialty, and specific-causation analysis aligned to Parker's requirement. The tool flags reports that rely on personal experience without published support, methodology with analytical gaps, and qualifications that don't match the defendant's specialty. It maintains a state-specific precedent library that includes Wesley, Parker, Cornell, the continuous treatment doctrine line, and Lavern's Law mechanics — so the case posture can be aligned to the gatekeeping standard the trial court will apply.
For the damages side, MedLegal AI's damages calculator projects damages under the CPLR 50-A structured-judgment framework, so case-selection economics can be modeled at intake with the structured-payout downside built in.

New York med-mal practice in 2026 has the longest working limitations period in plaintiff-friendly territory, no statutory damages cap, and a Frye reliability framework that functions like federal Daubert in practice. The cases that work in this environment are continuous-treatment-aware, CPLR 3012-a documented at engagement, Parker-grade in their expert reports, and CPLR 50-A modeled at intake. Firms that build the procedural and expert posture cleanly capture an unusually plaintiff-favorable damages framework. Firms that don't, lose to Frye exclusion at the trial court level and never see the substantive case.
