Another look at MUA

By Jason Tenenbaum 2 min read

Key Takeaway

New York court ruling on MUA expert testimony qualifications in no-fault insurance cases, examining when medical experts can testify outside specialty areas.

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. For personalized legal advice about how these principles apply to your specific situation, contact our Long Island office at (516) 750-0595 for a free consultation.

Drew De Marco, P.C. v Allstate Ins. Co., 2013 NY Slip Op 52212(U)(App. Term 1st Dept. 2013)

“uring Dr. Portnoy’s redirect testimony, the trial court precluded the witness from testifying as an expert on MUA procedures based on his acknowledgment that he was not certified to perform MUA. The Court thereupon directed a verdict in favor of plaintiff.”

“Dr. Portnoy was qualified as a chiropractic expert. Thus, he need not have been certified as an MUA specialist to offer an opinion as to the medical necessity of the MUA procedures here at issue (see Matter of Solano v City of Mount Vernon, 108 AD3d 676, 677 ). His lack of certification in this area goes to the weight to be accorded his testimony, not its admissibility (see Borawski v Huang, 34 AD3d 409, 410 ).”  New trial ordered.

This was the situation in Solano:

“Here, the hearing officer’s determination is supported by substantial evidence. The petitioner first contends that Dr. Silverman was not qualified to give an opinion. However, we have held that, “nce a medical expert establishes his or her knowledge of the relevant standards of care, he or she need not be a specialist in the particular area at issue to offer an opinion” (Texter v Middletown Dialysis Ctr., Inc., 22 AD3d 831, 831 ). Here, upon stipulation, Dr. Silverman was qualified as a medical expert. Thus, he need not have been a specialist to offer an opinion as to the petitioner’s condition. Moreover, contrary to the petitioner’s arguments, Dr. Silverman’s testimony was consistent and supported by the medical evidence. The hearing officer was free to credit Dr. Silverman’s testimony more than the testimony of the petitioner’s treating physician and chiropractor”

So, even though Dr. Portnoy does not engage in voodoo MUA, his testimony could establish a prima facie lack of medical appropriateness if his testimony is consistent and supported my medical evidence.  I think Solano is something to look into in the arbitration context when someone other than Cerf, Sposta or Sntkoff is your expert.


Legal Update (February 2026): Since this 2013 decision, New York’s regulations governing expert witness qualifications and testimony regarding medical procedures like MUA may have been modified through regulatory amendments or updated court precedents. Practitioners should verify current admissibility standards and expert qualification requirements, as evidentiary rules and medical necessity determination procedures are subject to periodic revision.

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.

This really comes down to a mistake in the judge’s wording. Instead of finding the testimony inadmissible, he should have found that the expert failed to establish a prima facie defense of a lack of medical necessity.
