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.

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.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. 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.
