Substitute peer allowed to testify on appeal

By Jason Tenenbaum 2 min read

Key Takeaway

Radiology Today's 2011 appeal restored a substitute doctor's opportunity to testify. Read the new-trial order and distinguish it from Jason's proposed remedy.

This article is part of our ongoing medical necessity coverage, with 170 published articles analyzing medical necessity issues across New York State. Attorney Jason Tenenbaum brings 24+ years of hands-on experience to this analysis, drawing from his work on more than 1,000 appeals, over 100,000 no-fault cases, and recovery of over $100 million for clients throughout Nassau County, Suffolk County, Queens, Brooklyn, Manhattan, and the Bronx.

The substitute doctor should have been heard. In Radiology Today, P.C. v Progressive Insurance Co., decided September 16, 2011, the Appellate Term reversed a provider’s judgment after the Civil Court excluded the insurer’s medical expert before any defense witness testified. The expert had not written the original peer review.

The appeal produced a new trial, not dismissal of the provider’s complaint. The court left open whether the written peer review itself could be admitted. Those distinctions matter when reading Jason’s proposed order below.

What the ruling actually decided

The trial had been limited to medical necessity under CPLR 3212(g). Excluding the substitute doctor prevented the insurer from presenting that defense. The appellate court corrected the exclusion without deciding which side should ultimately win.

The later Radiology Today v GEICO decision (2017) addresses the separate evidence problem: a peer review is not trial proof of the truth of its conclusions, but that does not prevent an expert from testifying. It also requires an appropriate objection if testimony exceeds the original basis for denial. Getting the doctor on the stand left the medical dispute to be tried.

Jason’s original comment

Jason’s September 2011 comment proposed a different remedy and discussed his view of the expense. Those existing historical figures and his accusation of frivolousness are commentary, not the court’s order or findings.

Again, I would write the order as follows. “Ordered, that the judgment is reversed, on the law, with $30 costs and the complaint is dismissed.”

Defendant spent $1000-$1500 for a doctor who could not testify based upon a palpably frivolous argument. The matter should either be dismissed with prejudice or Plaintiff should be compelled to pay Defendant the amount it expended on hiring an expert as a condition to this matter going to trial.

Historical note: Radiology Today’s September 2011 decision ordered a new trial after exclusion of a substitute expert; Radiology Today v GEICO (2017) later distinguished report admissibility, testimony scope and trial burdens. Last reviewed: September 2026.

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.

About This Topic

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.

Does the underlying peer review need to get into evidence?

6o.25. how else would the factfinder know you have the right guy? and isnt thw repeer more in the line of a confirmatory identification?
J
JT Author
CPL 60.25 is invoked when he witness cannot affirmatively identify the defendant and certain prerequisites are set forth. If the re-peer is relying on the original peer report and did not generate a report, then it would be cumulative and probably bolstering. If the adversary wants to put the peer in after the re-peer testifies, and the re-peer testifies is in accordance with the peer and he accepts its factual basis and medical rational as true, then it might come in as an inconsistent statement…

As usual Jason your complete and utter absence of knowledge of evidence rears its ugly head. I am sure there was request for expert information in this case. Its in every template. And if the insurance company designated anyone it had to be the Peer Review Doctor. If they failed to designate someone then they are out of luck. Moreover if they designated the Peer Review Doctor and showed up with someone totally different — which experience tells me they did — then the expert is precluded from testifying. That’s CPLR Jason. If you like I can give you and the App Term CPLR lessons — even just read it to you. Please make the arrangements with the Court.
