Court decision requiring medical experts to demonstrate proper qualifications when testifying outside their specialty area in NY personal injury cases.
Another Geffner sighting — Read Article →In-depth legal analysis from Attorney Jason Tenenbaum — covering court rulings, legal standards, and practical guidance on sufficiency of medical evidence under New York law.
Expert Analysis
The sufficiency of medical evidence is critical in both no-fault insurance claims and personal injury litigation. Courts scrutinize whether medical reports, affirmations, and affidavits are detailed enough to establish medical necessity, causation, and the extent of injuries. The form, content, and qualifications behind medical evidence are frequently challenged on summary judgment and at trial. These articles examine the standards courts apply when evaluating whether medical proof meets the prima facie burden or raises triable issues of fact.

Frequently Asked Questions
Sufficient medical evidence depends on the context. In no-fault cases, a treating physician's affirmation must specifically address and rebut the peer reviewer's findings with detailed clinical observations and reasoning — conclusory statements are insufficient. In personal injury cases, medical evidence must establish causation (linking injuries to the accident), the severity and permanence of injuries, and the necessity and reasonableness of treatment through objective clinical findings rather than subjective complaints alone.

His practice spans Nassau County, Suffolk County, Queens, Brooklyn, Manhattan, the Bronx, and Staten Island. He has handled thousands of cases involving insurance disputes, personal injury claims, and employment law matters, giving him a practical perspective that academic commentators often lack.

Call (516) 750-0595 to speak with an attorney, or visit the contact page to submit a case review request online. No fee is charged unless the firm recovers compensation on your behalf.

Attorney Tenenbaum is admitted to practice in New York, New Jersey, Florida, Texas, Georgia, and Michigan state courts, as well as multiple federal courts, and he has authored more than 2,353 published legal articles that attorneys, judges, and insurance professionals across the state rely on for guidance.
New York's legal framework for sufficiency of medical evidence matters involves an intricate web of statutes, regulations, and case law that has developed over decades. The state's court system — including the Civil Court, District Courts, Supreme Court, Appellate Term, Appellate Division, and Court of Appeals — each plays a distinct role in shaping how sufficiency of medical evidence cases are litigated and decided. Trial-level decisions in Nassau County Supreme Court, Suffolk County Supreme Court, and the New York City Civil Courts establish important factual precedents, while appellate rulings create binding legal standards that all lower courts must follow.
The Civil Practice Law and Rules (CPLR) governs procedure in New York civil litigation and contains provisions that directly impact sufficiency of medical evidence cases. CPLR Article 31 establishes the scope and methods of disclosure, including depositions under CPLR 3107, interrogatories under CPLR 3130, and document demands under CPLR 3120. CPLR 3212 provides the standard for summary judgment, requiring the movant to establish a prima facie case through admissible evidence and shifting the burden to the opponent to raise a triable issue of fact. CPLR 3215 governs default judgments, which require proof of service, proof of the facts constituting the claim, and proof of the amount due. Understanding these procedural tools is essential for anyone involved in sufficiency of medical evidence litigation in New York.
Statutes of limitations vary significantly depending on the type of claim. General negligence and personal injury claims carry a three-year deadline under CPLR 214(5). Medical malpractice claims have a shortened two-and-a-half-year deadline under CPLR 214-a. Claims against municipalities require a Notice of Claim within 90 days under General Municipal Law Section 50-e. No-fault insurance claims have their own regulatory deadlines, including the 30-day filing window for applications and the 45-day submission period for provider claims. Employment discrimination claims under the New York State Human Rights Law generally have a three-year statute of limitations, while federal Title VII claims require EEOC filing within 300 days.
The Appellate Term and Appellate Division regularly issue decisions that clarify and refine the legal standards applicable to sufficiency of medical evidence cases. The Second Department, which covers Long Island and parts of New York City, is particularly active in this area. Its decisions on evidentiary standards, burden-shifting frameworks, and procedural requirements directly affect how trial courts evaluate motions and how attorneys prepare their cases. Attorney Tenenbaum monitors these decisions and analyzes them in the articles on this page, providing practitioners with the timely legal commentary they need to stay current.

If you need help with a sufficiency of medical evidence matter, call (516) 750-0595 for a free consultation.
Successful outcomes in sufficiency of medical evidence cases often depend on procedural compliance as much as substantive merit. In no-fault insurance litigation, the prima facie case standard requires the plaintiff to submit admissible evidence establishing the claim was properly submitted, overdue, and unpaid. If the defendant raises a defense — such as an IME no-show, EUO non-appearance, lack of medical necessity, or fee schedule dispute — the burden shifts to the plaintiff to present evidence creating a triable issue of fact. Summary judgment motions under CPLR 3212 require the movant to make a prima facie showing through affidavits, deposition testimony, or documentary evidence, and the opposition must raise a genuine factual dispute to avoid dismissal.
In personal injury cases, the discovery process is governed by CPLR Article 31 and involves depositions of parties and witnesses, exchange of medical records under CPLR 3121 authorizations, physical and mental examinations, and expert disclosure. Once discovery is complete, either party may file a note of issue certifying readiness for trial, after which a 120-day deadline applies for filing summary judgment motions under CPLR 3212(a). Motion practice often determines the outcome of cases before trial, and understanding the specific evidentiary standards applied by courts in your jurisdiction is essential. The articles on this page analyze these standards in detail, drawing on real cases litigated by Attorney Tenenbaum and decisions from courts across the state.
The firm serves clients throughout Long Island, including the towns and villages of Huntington, Babylon, Islip, Brookhaven, Smithtown, Hempstead, Garden City, Mineola, Great Neck, Freeport, Long Beach, Rockville Centre, Valley Stream, Westbury, Hicksville, and Massapequa, as well as all five boroughs of New York City.
