Eastern Star Acupuncture lost the two claims on appeal because its opposition did not answer the insurer’s medical evidence. A medical professional’s signature was not enough.

What Eastern Star decided

The March 8, 2010 opinion, 2010 NY Slip Op 50380(U), concerned two claims that the Civil Court had left for trial. Mercury submitted an affidavit from the chiropractor/acupuncturist who performed the independent medical examination, together with an affirmed IME report. The Appellate Term, Second Department, found that evidence sufficient to establish lack of medical necessity for the services at issue.

The provider’s supervising acupuncturist did not meaningfully address the IME conclusions. The appellate court reversed the appealed portion of the order and granted dismissal of those claims. The opinion does not support saying that every claim in the action was dismissed or that the provider owed the insurer attorney’s fees.

Why the response failed

The court applied Pan Chiropractic v Mercury, 2009 NY Slip Op 51495(U). In Pan, the opposing affidavit simply disagreed with the reviewer without discussing the determination. Eastern Star applied that reasoning to an IME-based motion.

Every case is different. Get a free, confidential case review from an experienced attorney who can tell you exactly where you stand.

Read the medical evidence before drafting the response. Identify the services disputed, the examiner’s reason for finding them unnecessary and the opposition’s response to that reason. Length does not cure a missing response to the examiner.

Compare Complete Radiology’s successful treating-physician letter. That result does not give treating doctors an automatic preference. Both decisions concern whether the particular papers created a factual dispute after the insurer made its initial showing.

These are summary-judgment decisions. They do not establish an affidavit word count, a same-specialty requirement for every dispute or a universal rule for arbitration.

Historical note: This 2010 ruling concerns inadequate opposition to an IME-based summary-judgment motion; Pan Chiropractic supplies the cited rebuttal analysis, while the medical-necessity hub separates proof of the defense from denial timing.

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.

Frequently Asked Questions

Common Questions About This Topic

5 answers from the firm's New York personal-injury and employment-law practice. Click any question to expand.

What did the court rule in Eastern Star Acupuncture v Mercury Insurance?

The Appellate Term reversed the appealed portion of the order and dismissed the two claims at issue. Mercury's IME evidence established lack of medical necessity, and the supervising acupuncturist's affirmation did not meaningfully address it.

Why do conclusory affidavits fail in medical necessity summary judgment motions?

In Eastern Star and Pan Chiropractic, the opposition failed to engage the insurer's medical reasoning. A statement of disagreement did not create a factual dispute after the insurer made its initial showing.

What is a medical necessity summary judgment motion in New York no-fault cases?

It asks a court to decide the disputed claims without trial based on the submitted evidence. Eastern Star concerned an insurer's motion directed to particular treatment claims, not a determination of every possible coverage issue.

How can medical providers on Long Island defeat summary judgment on medical necessity?

Compare the examiner's findings with the opposing medical evidence. Complete Radiology shows that a treating-physician letter can raise a factual dispute; Eastern Star shows that the professional's title alone does not answer the report.

What happens if a medical provider loses a summary judgment motion?

The claims covered by the judgment may be dismissed. Eastern Star dismissed the two claims on appeal without costs; it did not establish an automatic obligation to pay the insurer's attorney's fees.

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.
