A potent dissent

By Jason Tenenbaum 8 min read

Key Takeaway

A dissenting judge criticizes vague peer review reports in no-fault insurance cases, highlighting the importance of detailed medical necessity determinations.

No-fault insurance cases often turn on peer review reports that assess whether medical treatments were necessary. These reports serve as critical evidence when insurance companies deny claims, but the quality and detail of these evaluations can vary significantly. In MSSA Corp. v Redland Insurance Company, a dissenting opinion shed light on what constitutes an adequate peer review analysis.

The case illustrates ongoing tensions in New York No-Fault Insurance Law regarding the standards for peer review reports. While some courts accept minimal explanations from reviewing physicians, others demand more comprehensive analysis to justify treatment denials.

Jason Tenenbaum’s Analysis:

MSSA Corp. v Redland Ins. Co., 2011 NY Slip Op 51606(U)(App. Term 2d Dept. 2011).

A case more remarkable for Justice Steinhardt’s dissent:

“In the instant matter, the peer review report of Dr. Ross did not “shed any light” on the assignor’s condition, nor did it state, in any sufficiently detailed manner, the reason the medical equipment at issue was not needed. The reader of the report is at a total loss to determine what actually happened to the assignor and what parts of her anatomy are amiss and in what way. “Bilateral shoulder and left elbow” injuries may range from a complicated fracture to a minor contusion. Without more, the report is conclusory and vague, and insufficient to shift the burden to plaintiff. I therefore vote to affirm the order denying defendant’s motion for summary judgment.”

The question here involves what needs to be in a peer review to demonstrate prima facie a lack of medical necessity for rendered services. It is interesting that certain judges are reading these peer reports in a more than perfunctory manner.

Key Takeaway

Justice Steinhardt’s dissent emphasizes that peer review reports must provide specific, detailed analysis rather than conclusory statements. Vague descriptions of injuries without proper context fail to establish a prima facie case for denying medical necessity, as seen in other medical necessity reversals where insufficient peer review documentation led to unfavorable outcomes for insurers.


Legal Update (February 2026): Since this 2011 analysis of peer review standards, New York’s Department of Financial Services has amended various no-fault regulations and fee schedules that may affect peer review requirements and medical necessity determinations. Additionally, subsequent appellate decisions may have further refined the standards for adequate peer review reports in medical necessity disputes. Practitioners should verify current regulatory provisions and recent case law developments when evaluating peer review adequacy.

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.

“interesting” J.T. don’t urinate on my back and tell me its raining. Some judges are not reading them at all because they have an industry agenda. The pendulum (sp?)has reached its highest apex and seems to just hover. Somewhere in there the insurance companies poured more money into the state then the trial lawyers. When I interviewed for a job with MetLife — disability; long term care and dental became my territory — I told the head of their general counsel — the general counsel a very powerful man — that if the insurance industry combined money they could crush the trial lawyers. 11 years later I am demonstrated as correct. Hell I probably started it.

Of course, we know that this Term has been relaxing the summary judgment burdens in favor of one particular class of litigants for serveral years now. Apparently, there is now some dissent in the ranks, literally. One insane example in many, which actually illustrates this Term denying due process to the insured and its assignor, is found here (combined with some of my discussion taken from a Brief directed to a different appellate court): In Acupuncture Works, the Appellate Term inappropriately granted the insurer summary judgment premised upon speculation that the insurer might have failed to issue a follow-up demand for verification. Acupuncture Works, P.C. v. MVAIC, 2010 NY Slip Op 50646U, 1-2 (N.Y. App. Term 2010). Indeed, as the Term provided therein, “While a review of the record reveals that defendant may have initially tolled its time to pay or deny the claim by the issuance of a request for verification on June 10, 2002 … the record does not contain any indication that defendant timely issued a follow-up verification request (see Insurance Department Regulations [11 NYCRR] § 65-3.6 [b]).” Id, emphasis added. The Appellate Term’s grant of summary judgment premised upon speculation that Appellant might not have followed-up on its own verification demand– even while no proof one way or the other was obviously provided– was highly erroneous and disregarded, in extreme fashion, the summary judgment standards continually reiterated by the Court of Appeals and Appellate Divisions. And this does not even address the aspect that the Term allowed this insurer to receive a windfall at the expense of the insured simply in light of counsel for the insurer’s necessary suggestion that the insurer fails to comply with the follow-up regulations in systematic and continual fashion. There was a time when breaking the law went against you, rather than for you. Does anyone from the insurance bar or Appellate Term 2nd want to defend Acupuncture Works? If so, JT can start a unique thread for that, and I will debate the point for the side of due process. …the silence will be deafening.

LOl, sorry JT, perhaps I got a little out of hand, that was NOT directed at you, of course.

Now I direct it at him. JT Sun’s treatise is now directed at you. Just what do you have to say for yourself young man. You should be roundly caned. In unrelated news I heard Rogak gave a Lecture Series on New York No Fault Law a few days back in the Bahamas. Now we’ve got all this hot air and wind threatening to wreck our beach weekend.

I am busy editing Mercury v. Encare right now – I am trying to get this thing on for the November term so the defense bar can have a happy New Year. I will respond to Sun’s treatise later. Now, as to Rogak’s summer no-fault series, well I will not comment. I will say though that if he keeps saying that the DOI’s proclamation that a carrier must issue a global denial should be ignored, then I might try to enlist Chris Malone from the DOI to clarify this issue again.

There are some really bad peer reviews. For the 2d Dept, I can only imagine how bad it would have to be to split the judges. Unless I’m mistaken, a dissent means the ability to appeal as of right to App Div.
J
JT Author
You are mistaken. But, I wouldn’t be surprised if the App Div. 2nd Dept finally takes up this issue should a proper application be made.

Raymond Zuppa
I thought a dissent gave you an automatic shot at the App Div too. What is “proper application” mean. C’mon now JT. Only you know what a “proper application” is? I get it. That’s right I am hip. Everyone hire J.T. because only knows what’s proper. Using facts and precedent to demonstrate the decision was wrong and highlighting the importance of review is not enough. It has to be JT proper.

If the peer review is as bad as the dissent intimates it is, and leave is granted, then I hope Redland pays this out. This is not the kind of precedent that is needed right now.

raymond zuppa
J.T. you have to read some of these Peers. They are worse then the letters of medical necessity. I had one Peer state (DME) that it was just to much so don’t pay on anything. On cross the doctor stated that he made absolutely no item by item inquiry as to whether the particular item was medically necessary. He based his entire opinion on “its just too much.” Because I am Zuppa and can win everywhere except in anything related to No Fault — where I can’t win a thing — the judge in his infinite wisdom ruled the items were not medically necessary. I laughed and said what does it take to win. The Judge said if they have a witness they are going to win unless you really destroy him on cross. I asked the Judge if he was expecting a Perry Mason like breakdown on the stand or if he wanted me to go further and actually ring the miscreant’s neck. To his credit he was amused but kicked me out anyway.

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.

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.
