Understanding Medical Necessity Defense Failures in New York No-Fault Insurance Cases

When dealing with New York’s complex no-fault insurance system, understanding how medical necessity defenses can fail is crucial for both healthcare providers and legal professionals throughout Long Island and New York City. A recent Appellate Term decision provides valuable insight into the procedural requirements and evidentiary standards that can make or break a medical necessity defense.

Progressive Med., Inc. v Allstate Ins. Co., 2010 NY Slip Op 50219(U)(App. Term 2d Dept. 2010) serves as a critical example of how insurance carriers can lose medical necessity defenses due to inadequate foundational evidence and hearsay issues.

The Court’s Analysis of Expert Testimony

“On cross-examination, the witness testified that he relied on several out-of-court documents in reaching his conclusion. He also testified that, in his report, he referred to a report from his board- certifying academy regarding one type of equipment at issue. Although plaintiff had previously stipulated to qualifying the witness as an expert, its attorney subsequently objected to this testimony on the ground that it was based upon records that were not in evidence and upon a study, the reliability of which had not been established. The court sustained the objection and ordered the testimony stricken.

“Based upon the court’s statements that the only issue for trial was medical necessity and that a claim form had been submitted and timely denied, as well as defendant’s presentation of its witness instead of moving for judgment pursuant to CPLR 4401, we find that the parties agreed that the sole issue for trial was defendant’s defense of lack of medical necessity. The record [*2]reveals no basis, under the specific facts of this case, for the court’s finding that plaintiff was required to submit a claim form in order to establish, prima facie, “the health benefit’s medical necessity.””

On the other hand, on the scant record provided to this court, there is no basis to disturb the court’s decision to strike defendant’s witness’s testimony. Plaintiff advanced what was, in effect, a hearsay objection. Defendant failed to demonstrate either that the testimony did not rely on out-of-court documents for the truth of the matters stated therein, or that the documents were being relied upon for their truth but fell within an exception to the rule against hearsay. Consequently, we cannot say that it was an improvident exercise of discretion for the court to strike the testimony.”

Expert Analysis: The Foundation Failure

It looks like the attorney for the defense failed to lay a proper foundation to allow the doctor to testify about the medical records. What needed to be asked was: how the doctor received the records; what they represented; whether the assignor’s name was on the records; whether the date of loss on the records corresponded to when the accident occurred; whether the claim number on the documents matched the actual claim number; whether there was other information that would correlate the documents to the assignor; and the veracity of the journal articles.

The courts in the realm of no-fault litigation will generally allow an expert to testify about the documents that purport to be those representing the treatment of the alleged assignor. The only thing an attorney has to do is find some correlating link between the medical reports and the assignor. That link is almost always in the reports. If the link is not there, then look further – you should find it. If you cannot find that link at all, then the doctor probably did not review the entire medical record, and this is rife with its own issues, none of which are good for the insurance carrier.

This case also asks the following question: how can a medical necessity summary judgment motion be made without annexing the medical records? Presumably, the attached medical records allow for the inference that they represent the treatment notes of the alleged assignor. Without those notes, it looks like a peer review by itself must fail on constraint of this case and the others I have previously discussed.

Implications for Long Island and NYC Healthcare Providers

For healthcare providers operating throughout Nassau County, Suffolk County, Queens, Brooklyn, Manhattan, and the Bronx, this decision highlights several critical considerations when dealing with no-fault insurance claims and potential litigation:

Documentation Requirements

Healthcare providers must ensure that all medical records contain clear identifying information linking the treatment to the specific patient and accident. This includes maintaining accurate patient identification, accident dates, claim numbers, and comprehensive treatment notes that can withstand legal scrutiny.

Expert Testimony Preparation

When insurance carriers challenge medical necessity, the expert witnesses they employ must be properly prepared to establish foundational requirements for their testimony. This case demonstrates that even qualified experts can have their testimony stricken if proper procedural requirements aren’t met.

Strategic Considerations for No-Fault Practitioners

This decision provides several strategic insights for attorneys practicing in New York’s no-fault insurance arena:

For Plaintiff’s Counsel

Understanding how to effectively challenge expert testimony based on hearsay objections can be a powerful tool. When insurance company experts rely on out-of-court documents without proper foundation, aggressive objections can result in testimony being stricken.

For Defense Counsel

Insurance carriers and their counsel must ensure that expert witnesses are properly prepared to establish the reliability and admissibility of any documents or studies they reference. The failure to do so can result in the complete collapse of a medical necessity defense.

The Broader Context of New York No-Fault Law

New York’s no-fault insurance system creates unique challenges for both healthcare providers and insurance companies. The system is designed to provide prompt payment for necessary medical treatment following motor vehicle accidents, but disputes over medical necessity continue to generate significant litigation throughout the metropolitan area.

Cases like Progressive Medical highlight the technical nature of these disputes and the importance of proper legal representation for all parties involved. Whether you’re a healthcare provider seeking payment for services rendered or an insurance company defending against claims, understanding these procedural requirements is essential.

Frequently Asked Questions

Q: What is medical necessity in the context of no-fault insurance?

A: Medical necessity refers to healthcare services that are reasonable, necessary, and appropriate for the diagnosis or treatment of an injury resulting from a covered accident. Insurance companies may deny claims they deem medically unnecessary.

Q: Can expert testimony be stricken for relying on out-of-court documents?

A: Yes, as this case demonstrates, expert testimony can be stricken if it relies on out-of-court documents for their truth without proper foundation or if the documents don’t fall within a hearsay exception.

Q: What should healthcare providers do to protect themselves in no-fault disputes?

A: Maintain comprehensive, accurate medical records with clear patient identification and treatment justification. Ensure all documentation clearly links the treatment to the specific accident and patient.

A: Extremely important. As this case shows, technical procedural errors can result in the complete failure of otherwise valid defenses or claims.

Legal Update (February 2026): Since this 2010 decision, New York’s no-fault insurance regulations have undergone multiple amendments affecting medical necessity determinations and expert testimony standards. Additionally, the fee schedules referenced in Insurance Regulation 68 have been updated several times, and procedural requirements for challenging medical necessity may have been modified through regulatory changes and subsequent appellate decisions. Practitioners should verify current provisions in Insurance Regulation 68 and review recent case law for updated evidentiary standards in medical necessity disputes.

Legal Context

Why This Matters for Your Case

New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.

Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

Understanding New York Evidence Law

New York has a unique legal landscape that affects how evidence cases are litigated and resolved. The state's court system includes the Civil Court (for claims up to $25,000), the Supreme Court (the primary trial court for unlimited jurisdiction), the Appellate Term (which hears appeals from lower courts), the Appellate Division (divided into four Departments, with the Second Department covering Long Island, Brooklyn, Queens, Staten Island, and several upstate counties), and the Court of Appeals (the state's highest court). Each court has its own procedural requirements, local rules, and case-assignment practices that can significantly impact the outcome of your case.

For evidence matters on Long Island, cases are typically filed in Nassau County Supreme Court (at the courthouse in Mineola) or Suffolk County Supreme Court (in Riverhead). No-fault arbitrations are heard through the American Arbitration Association, which assigns arbitrators throughout the metropolitan area. Workers' compensation claims go to the Workers' Compensation Board, with hearings at district offices across the state. Understanding which forum is appropriate for your case — and the specific procedural rules that apply — is essential for a successful outcome.

The procedural landscape in New York also includes important timing requirements that can affect your case. Most civil actions are subject to statutes of limitations ranging from one year (for intentional torts and claims against municipalities) to six years (for contract actions). Personal injury cases generally have a three-year deadline under CPLR 214(5), while medical malpractice claims must be filed within two and a half years under CPLR 214-a. No-fault insurance claims have their own regulatory deadlines, including 30-day filing requirements for applications and 45-day deadlines for provider claims. Understanding and complying with these deadlines is critical — missing a filing deadline can permanently bar your claim, regardless of how strong your case may be on the merits.

Attorney Jason Tenenbaum regularly practices in all of these venues. His office at 326 Walt Whitman Road, Suite C, Huntington Station, NY 11746, is centrally located on Long Island, providing convenient access to courts and offices throughout Nassau County, Suffolk County, and New York City. Whether you need representation in a no-fault arbitration, a personal injury trial, an employment discrimination hearing, or an appeal to the Appellate Division, the Law Office of Jason Tenenbaum, P.C. brings $24+ years of real courtroom experience to your case. If you have questions about the legal issues discussed in this article, call (516) 750-0595 for a free, no-obligation consultation.

New York's substantive law also presents distinct challenges. In motor vehicle cases, the no-fault system under Insurance Law Article 51 provides first-party benefits regardless of fault, but limits the right to sue for non-economic damages unless the plaintiff establishes a "serious injury" under one of nine statutory categories. This threshold — codified at Insurance Law Section 5102(d) — requires medical evidence showing more than a minor or subjective injury, and courts have developed detailed standards for each category. Fractures must be documented through imaging studies. Claims of permanent consequential limitation or significant limitation of use require quantified range-of-motion testing with comparison to norms. The 90/180-day category demands proof that the plaintiff was unable to perform substantially all of their usual daily activities for at least 90 of the 180 days following the accident.

In employment discrimination cases, the legal standards vary depending on whether the claim arises under state or local law. The New York State Human Rights Law employs a burden-shifting framework: the plaintiff must first establish a prima facie case by showing membership in a protected class, qualification for the position, an adverse employment action, and circumstances giving rise to an inference of discrimination. The burden then shifts to the employer to articulate a legitimate, non-discriminatory reason for its decision. If the employer meets this burden, the plaintiff must demonstrate that the stated reason is pretextual. The New York City Human Rights Law, by contrast, applies a broader standard, asking whether the plaintiff was treated less well than other employees because of a protected characteristic.
