Pomona Med. Diagnostic P.C. v Adirondack Ins. Co., 2012 NY Slip Op 51165(U)(App. Term 1st Dept. 2012)

Defendant appeared to work under a novel theory that it could use discovery to figure out who is primary and, in the alternative, to find out if Plaintiff was fraudulentally incorporated.  Defendant’s attempt to obtain discovery on the first score was a loser, on the law.  Defendant’s attempt to obtain discovery on the second score was a loser, on the law.

“The defendant insurer’s motion to strike the notice of trial and compel discovery should have been denied. Insofar as defendant sought discovery pertaining to its affirmative defense that another insurance carrier was primarily liable, the information was immaterial and, in result, the demands were palpably improper (see Duhe v Midence, 1 AD3d 279 ), since defendant cannot properly rely on this defense as a basis to deny plaintiff’s no-fault claim (see 11 NYCRR 65-3.12; M.N. Denatal Diagnostics, PC v Government Empl. Ins. Co., 81 AD3d 541 ). Nor has defendant set forth any case-specific allegations in support of its defense that plaintiff was fraudulently incorporated so as to justify discovery on this issue (cf. One Beacon Ins. Group, LLC v Midland Med. Care, PC, 54 AD3d 738 ). Defendant “will not be allowed to use pretrial discovery as a fishing expedition when they cannot set forth a reliable factual basis for what amounts to, at best, mere suspicions” (Devore v Pfizer Inc., 58 AD3d 138, 144 , lv denied 12 NY3d 703 ).”


Legal Update (February 2026): Since this 2012 decision, New York’s no-fault regulations under 11 NYCRR Part 65 have undergone multiple amendments, including updates to priority of coverage provisions and discovery limitations in no-fault litigation. Additionally, appellate courts have continued to refine the standards for when discovery may be permitted regarding fraudulent incorporation defenses and priority disputes. Practitioners should verify current regulatory provisions and recent case law developments when addressing similar coverage priority and discovery issues.

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.

The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.

The Court is correct with regard to discovery regarding priority of payment. Under the priority of payment regulations, the first insurer to receive the claim is obligted to pay and then can seek recovery in inter-company priorty of payment arbitration under section 5015(b) of the Insurance Law. The purpose behind the priorty of payment regulation is to provide quick efficient compensation to the injured party and allow the insurers an opportunity to fight it out later amongst themselves.

I agree with Mitch. Priority of payment is neither a defense nor a discovery issue.

“case specific allegations”. Does this put an end to the boilerplate verification requests issued to providers and knee jerk motions to vacate notices of trial?

This has to be one of the most stinging defeats for the carriers on the corporate discovery type issues that I have seen in years. Just amazing how the carrier in this case on really bad facts created awful law.

Finally someone said “Enough” to knee jerk discovery.

Its aweful when the court gets it right.

Does anyone think this decision deviates from the existing standard of requiring a “founded belief” in order to do Malella discovery? I don’t.

There’s a “founded belief” standard to get Mallela discovery?

As Martin Sheen told Colonel Kurtz in Apocalypse Now: “Frankly I do not see any method.” Well frankly I do not see an Malella standard save one … ask insurance company and the insurance Gods a.k.a. the Courts of New York State — will make sure you receive so you can delay and screw people up. How easy it is to be a defense attorney for an insurance company. Demand every friggin thing on every case and make the cost of discovery exceed the value of the case. In the future I plan to make the insurance companies pay for every copy — 50 cents a page for material and time — that I make. I want the check in hand and deposited and cleared before I send the discovery. And in support of my demand I will state: “We gave them this a million times.”

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. 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.
