Medical necessity remains one of the most frequently litigated issues in New York no-fault insurance cases, particularly when insurers deny claims for durable medical equipment and medical supplies based on peer review determinations. The burden-shifting framework governing summary judgment motions in medical necessity cases requires insurers to establish prima facie that the disputed treatment or supplies lacked medical necessity, typically through peer review reports from qualified physicians. Once the insurer meets this initial burden, the burden shifts to the plaintiff medical provider to raise a triable issue of fact regarding medical necessity through competent medical evidence.

The quality and specificity of medical affidavits submitted in opposition to summary judgment motions determines whether providers successfully defeat dismissal of their claims. Courts have consistently held that conclusory medical affidavits lacking specific connection between the patient’s condition and the disputed treatment fail to raise triable issues of fact. Conversely, medical affidavits that articulate the patient’s specific medical conditions, explain how those conditions necessitated the disputed treatment or supplies, and describe the therapeutic benefits of the treatment create factual disputes requiring trial resolution.

In the context of durable medical equipment and supplies, establishing medical necessity presents particular challenges because peer reviewers may question whether standard items like orthopedic braces, TENS units, or cervical pillows provide therapeutic benefit beyond placebo effect or comfort. Medical providers must therefore present opposition evidence that articulates specific medical justifications for each item based on the patient’s particular injuries and functional limitations. Generic statements about the benefits of supplies generally do not suffice; the affidavit must connect the specific supplies to the specific patient’s specific medical needs.

Case Background

In Five Boro Medical Equipment, Inc. v A. Central Insurance Company, the plaintiff medical supply company sought payment for durable medical equipment provided to a patient following a motor vehicle accident. The defendant insurer denied the claims based on peer review reports from a chiropractor who opined that the supplies lacked medical necessity. The insurer moved for summary judgment, submitting evidence that its denial of claim forms were timely and properly mailed, and that its peer review reports were in admissible form.

The plaintiff opposed the motion with a medical affidavit from a physician who had evaluated the patient and prescribed the disputed medical supplies. The affidavit specified the patient’s medical conditions resulting from the accident, including musculoskeletal injuries and functional limitations. For each category of medical supplies that had been denied, the physician’s affidavit described the intended therapeutic benefits and explained how those supplies addressed the patient’s specific medical needs arising from the accident-related injuries.

The Civil Court initially granted the defendant’s summary judgment motion, apparently finding the insurer’s peer review evidence sufficient to establish lack of medical necessity as a matter of law. The plaintiff appealed to the Appellate Term, First Department, arguing that its medical affidavit raised triable issues of fact precluding summary judgment.

Jason Tenenbaum’s Analysis

Five Boro Med. Equip., Inc. v A. Cent. Ins. Co., 2016 NY Slip Op 50412(U)(App. Term 1st Dept. 2016)

(1) The defendant-insurer’s motion for summary judgment dismissing this first-party no-fault action should have been denied. Initially, we note that Civil Court correctly determined that defendant’s documentary submissions were sufficient to establish, prima facie, that its denial of claim forms were timely and properly mailed (see Preferred Mut. Ins. Co. v Donnelly, 22 NY3d 1169 ; AutoOne Ins./General Assurance v Eastern Island Med. Care, P.C., _____ AD3d_____, 2016 NY Slip Op 00916 ), and that the peer review reports of defendant’s chiropractor were in admissible form”

(2) However, the medical affidavit submitted by plaintiff, which specified the assignor’s medical conditions and described the intended benefits of each of the medical supplies at issue, was sufficient to raise a triable issue of fact as to medical necessity [*2](see AutoOne Ins./General Assurance v Eastern Island Med. Care, P.C., supra; Amherst Med. Supply, LLC v A. Cent. Ins. Co., 41 Misc 3d 133, 2013 NY Slip Op 51800).

I should have brought suit as “Autoone Ins Co. v. Eastern Island Med. Care, P.C”. I think I let someone work here name Plaintiff as “Autoone Ins./General Assurance”. That name is too long.

Substantively, the Court found issues of fact since the affidavit of merit related the supply to the injury. I am sure it is boilerplate, but look at the industry.

The Appellate Term’s decision in Five Boro Medical Equipment reinforces established principles governing opposition to medical necessity summary judgment motions while providing practical guidance regarding the level of specificity required in medical affidavits. The court’s holding acknowledges that insurers can establish prima facie cases through proper peer review procedures, but emphasizes that medical affidavits connecting specific supplies to specific patient conditions create factual disputes requiring resolution at trial rather than on summary judgment.

The decision’s significance lies in its recognition that medical affidavits need not be exhaustive medical treatises to raise triable issues of fact. By holding that an affidavit specifying the patient’s medical conditions and describing the intended benefits of each disputed supply suffices to defeat summary judgment, the court adopted a practical standard that medical providers can satisfy without producing novel medical research or extensive literature reviews. The affidavit must demonstrate medical reasoning connecting the supplies to the patient’s needs, but need not conclusively prove medical necessity at the summary judgment stage.

This standard reflects appropriate application of summary judgment principles in the medical necessity context. Summary judgment is a drastic remedy appropriate only when no genuine factual disputes exist. Medical necessity inherently involves professional medical judgments about which qualified practitioners may reasonably disagree. When a plaintiff’s medical expert articulates a reasoned basis for concluding that supplies were medically necessary based on the patient’s specific condition, and the defendant’s peer reviewer reaches a contrary conclusion, a factual dispute exists that cannot be resolved on the papers.

The court’s citation to AutoOne Insurance/General Assurance v Eastern Island Medical Care and Amherst Medical Supply v A. Central Insurance Company demonstrates consistency in First Department jurisprudence requiring meaningful engagement with the patient’s specific medical condition in opposition affidavits. These precedents establish that generic affidavits discussing supplies in the abstract fail to raise issues of fact, but affidavits that address the particular patient’s particular needs succeed in defeating summary judgment.

Practical Implications

Medical providers and their attorneys defending against medical necessity summary judgment motions must ensure that opposition affidavits contain specific content connecting the disputed treatment or supplies to the patient’s documented medical conditions. The affidavit should identify each denied item, explain the patient’s medical condition requiring that item, and describe the therapeutic benefit that item provides for the patient’s specific condition. Generic statements about supplies being “necessary for the patient’s condition” without particularized explanation will not suffice.

Insurance carriers and defense counsel should not assume that peer review reports automatically entitle them to summary judgment. When providers submit medical affidavits containing the specificity demonstrated in Five Boro Medical Equipment, factual issues exist precluding dismissal. Defense counsel should carefully review opposition affidavits to determine whether they truly engage with the specific patient and specific supplies, or merely offer conclusory assertions. Where affidavits lack specificity, reply papers should identify those deficiencies.

The decision also highlights practical case naming considerations for medical providers. As Jason Tenenbaum notes, unnecessarily long party names create administrative burdens. Medical providers should use concise entity names that clearly identify them without excessive designation of doing business names or multiple corporate identities. While this is not a legal requirement, it reflects professional practice considerations.

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.

Medical Necessity Disputes in No-Fault Insurance

Medical necessity is the most common basis for no-fault claim denials in New York. Insurers hire peer reviewers to opine that treatment was not medically necessary, shifting the burden to providers and claimants to demonstrate otherwise. The legal standards for establishing and rebutting medical necessity — including the sufficiency of peer review reports, the qualifications of reviewing physicians, and the evidentiary burdens at arbitration and trial — are the subject of extensive case law. These articles provide detailed analysis of medical necessity litigation strategies and court decisions.

Common Questions

Frequently Asked Questions

What is a medical necessity denial in no-fault insurance?

A medical necessity denial occurs when the insurer's peer reviewer determines that treatment was not medically necessary based on a review of the patient's medical records. The peer reviewer writes a report explaining why the treatment does not meet the standard of medical necessity. To challenge this denial, the provider or claimant must present medical evidence — typically an affirmation from the treating physician — explaining why the treatment was necessary and rebutting the peer review findings.

How do you challenge a peer review denial?

To overcome a peer review denial, you typically need an affirmation or affidavit from the treating physician that specifically addresses and rebuts the peer reviewer's findings. The treating physician must explain the medical rationale for the treatment, reference the patient's clinical findings, and demonstrate why the peer reviewer's conclusions were incorrect. Generic or conclusory statements are insufficient — the response must be detailed and fact-specific.

What criteria determine medical necessity for no-fault treatment in New York?

Medical necessity is evaluated based on whether the treatment is appropriate for the patient's diagnosed condition, consistent with accepted medical standards, and not primarily for the convenience of the patient or provider. Peer reviewers assess factors including clinical findings, diagnostic test results, treatment plan consistency with the diagnosis, and whether the patient is showing functional improvement. Treatment that is excessive, experimental, or unsupported by objective findings may be deemed not medically necessary.

Can an insurer cut off no-fault benefits based on one IME?

Yes, an insurer can discontinue benefits after a single IME doctor concludes that further treatment is not medically necessary or that the claimant has reached maximum medical improvement. However, the IME report must be sufficiently detailed and the denial must be issued within 30 days under 11 NYCRR §65-3.8(c). The treating physician can submit a rebuttal affirmation explaining why continued treatment is necessary, forming the basis for challenging the cut-off at arbitration.

What is a peer review in no-fault insurance?

A peer review is a paper-based evaluation where a licensed medical professional reviews the patient's records and renders an opinion on whether the billed treatment was medically necessary. Unlike an IME, the peer reviewer does not examine the patient. The peer review report must be detailed, address the specific treatment at issue, and explain the medical rationale for the opinion. Generic or boilerplate peer reviews that fail to address the patient's individual clinical presentation may be found insufficient.

Understanding New York Medical Necessity Law

New York has a unique legal landscape that affects how medical necessity 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 medical necessity 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.

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.
