Peer review

By Jason Tenenbaum 8 min read

Key Takeaway

Court ruling emphasizes that peer review reports must provide clear medical rationale and factual basis to successfully challenge medical necessity claims in no-fault cases.

Understanding Peer Review Standards in No-Fault Insurance Cases

In New York’s no-fault insurance system, insurance companies frequently challenge medical treatments through peer review reports to deny coverage based on alleged lack of medical necessity. However, these reports cannot simply conclude that treatment was unnecessary—they must provide substantial medical reasoning and factual support to withstand legal scrutiny.

The quality and thoroughness of peer review documentation plays a crucial role in determining whether an insurance company can successfully defend against claims for medical services. When peer reviewers fail to establish a comprehensive foundation for their conclusions, courts will reject their findings and rule in favor of healthcare providers seeking payment for legitimate medical services.

This principle protects both patients and medical practitioners from arbitrary insurance denials that lack proper medical justification. It ensures that medical necessity reversals are based on sound medical reasoning rather than conclusory statements designed to avoid payment obligations.

Jason Tenenbaum’s Analysis:

Midtown Med. Assoc., P.C. v Clarendon Natl. Ins. Co., 2012 NY Slip Op 51071(U)(App. Term 2d Dept. 2012)

“As the affirmed peer review report submitted by defendant failed to clearly establish a sufficient medical rationale and factual basis to demonstrate a lack of medical necessity for the services at issue defendant’s motion was properly denied.”

Key Takeaway

Insurance companies must ensure their peer review reports contain detailed medical analysis and factual support when challenging treatment necessity. While a copy of a peer report is all that is needed to submit the evidence, the content must be substantive. Conclusory statements without proper foundation will result in denied motions and potential liability for the disputed medical services under New York No-Fault Insurance Law.


Legal Update (February 2026): Since this post’s publication in 2012, New York’s no-fault insurance regulations governing peer review standards and medical necessity determinations may have been subject to amendments through regulatory updates or legislative changes. Additionally, evolving case law may have further refined the evidentiary standards required for peer review reports to withstand judicial scrutiny. Practitioners should verify current regulatory provisions and recent appellate decisions when evaluating the sufficiency of peer review documentation in medical necessity disputes.

Question. Why is the Court getting involved in reviewing the merits of the peer review.? By submitting the peer review, the insurer shifted the burden to the plaintiff. If the plaintiff does not submit an affidavit from the provider supporting the medical necessity of the services, the insurer should prevail. This case seems contrary to Khodadi Radiology and its progeny. In the context of a motion for summary judgment, the Court is not the ultimate trier of fact.

Mitchell, so if the peer review report literally says “Mary had a little lamb,” and nothing else, that shifts the burden to the provider? And without a rebuttal affidavit, the insurer wins summary judgment? Obviously the answer to both questions is “no.” The peer review report must establish, prima facie, that the services aren’t medically necessary. This is not, and should not be, a mechanical “if you have a peer review report, you automatically sustain your burden” inquiry. Consider, for example, the question of a defendant’s prima facie burden on the “serious injury” issue in bodily injury suits. The courts there have to review the merits of the experts’ reports/affidavits to determine whether a prima facie burden is met. And, of course, sometimes the burden isn’t met. See, e.g., this recent App. Div., 2d Dep’t decision going into the meat of the defendant’s report and determining that a prima facie case for a lack of a serious injury was not met: http://www.nycourts.gov/reporter/3dseries/2012/2012_04154.htm If anything, the Appellate Term should be doing more of this, not less of this.

You are right in an extreme circumstance where the peer review says “Mary had a little lamb.” But in most instances that is not the case. While the peer review may not be great, it usually contains a least an arguable basis that the services were not medically necessary. There are also numerous decisions from the Appellate Term dismissing cases based upon a peer review report where the court does not discuss the merits of the peer. Are we saying that in those cases the insurer’s peer review was unassailable. I still think a plaintiff is taking too big of a risk if it does not provide a medical affidavit and simply relies upon an attorney affirmation attacking the merits of the peer review report.
