Medical necessity and a triable issue of fact
This 2011 appeal concerns competing medical evidence. GEICO supported its motion with sufficient peer reviews, but the provider’s medical affirmation raised a triable issue. The court did not hold that boilerplate letters are automatically sufficient.
The case of Park Slope Med. & Surgical Supply, Inc. v GEICO Ins. Co., 2011 NY Slip Op 50188(U)(App. Term 2d Dept. 2011) demonstrates the continuing effectiveness of proper medical necessity affirmations in defeating insurance company challenges.
The Court’s Analysis of Medical Necessity Evidence
“laintiff submitted an affirmation of its doctor which sufficiently demonstrated the existence of a question of fact as to medical necessity (see Quality Psychological Servs., P.C. v Mercury Ins. Group, 27 Misc 3d 129, 2010 NY Slip Op 50601 ; Park Slope Med. & Surgical Supply, Inc. v New York Cent. Mut. Fire Ins. Co., 22 Misc 3d 141, 2009 NY Slip Op 50441 )”

Jason’s original, expressly qualified observation:
Knowing this provider and the citation to Quality Psychological (letter of medical necessity sufficient to defeat LOMN motion), it appears that Plaintiff proffered the Dr. Leonid Shapiro letter of medical necessity. Please note that I have not reviewed the record and do not have personal knowledge of these facts. If my facts are wrong, please let me know and I will make the appropriate changes in the post. History and practices in no-fault practice do not change themselves unless forced upon the dueling parties.
A denial of judgment is a limited result
The opinion resolves GEICO’s entitlement to judgment on the submitted record. It does not measure the success rate of motions by GEICO, Mercury or NYCM. Compare the medical explanation and the response, not the insurer’s identity.
Understanding Medical Necessity Standards in No-Fault Cases
The moving insurer must first support its defense. If that showing is made, the provider’s response must raise a triable issue; the analysis does not turn on the carrier’s identity.
Requirements for Effective Medical Necessity Affirmations
For medical providers throughout Long Island and New York City, understanding what constitutes an effective medical necessity affirmation is crucial for defending against insurance company challenges. Key elements typically include:
- Detailed explanation of the patient’s condition and symptoms
- Medical rationale for the specific treatments provided
- Professional opinion based on examination and medical records
- Explanation of how the treatment relates to the accident-related injuries
- Documentation of the provider’s qualifications and expertise
The opinion supports the response in this record, not a success rate for affirmations across insurers.
The unverified attribution in the original note
Jason expressly stated that he had not reviewed the record and lacked personal knowledge of the letter’s authorship. The attribution remains a historical observation, not a verified fact about this appeal.
Developing Effective Medical Necessity Documentation
Medical providers should work with healthcare professionals who understand the specific requirements for medical necessity affirmations in no-fault cases. This includes:
- Understanding the legal standards for medical necessity
- Ability to articulate medical rationale clearly
- Experience with no-fault insurance requirements
- Knowledge of common insurance company challenges
- Familiarity with court precedents and standards
A clinician should explain the disagreement that actually appears in the submitted reports.
Prepare the evidence, not an account of the insurer’s motives
Nothing in the published opinion identifies a delay strategy, an economic motive, or sanctionable conduct. A response should identify the disputed service, the peer review’s criticism, and the clinician’s basis for disagreement. Counsel can then explain why that evidence leaves an issue for trial.
Keep the denial and mailing proof with the medical reports. A defense may involve a timing issue as well as the merits. If the court already resolved timing or another issue under CPLR 3212(g), include that order in the trial file so the next lawyer does not treat it as an open question.
Practical Implications for Medical Providers in Long Island and NYC
The particular motion record supplies these preparation questions for healthcare providers:
Documentation Best Practices
Medical providers should implement comprehensive documentation practices to support medical necessity when challenged:
- Detailed initial examination records
- Clear documentation of symptoms and functional limitations
- Treatment plans with medical rationale
- Progress notes showing response to treatment
- Professional qualifications and expertise documentation
Working with Medical Necessity Experts
Developing relationships with medical professionals experienced in no-fault medical necessity documentation can be crucial for successful claim defense. This includes:
- Physicians familiar with no-fault legal standards
- Professionals who can articulate medical rationale clearly
- Experts with experience in contested cases
- Medical reviewers who understand insurance company tactics
Compare the actual records across carriers
A provider can learn from a successful response without assuming that the same letter answers every reviewer. The disputed treatment, clinical findings and criticism may differ. A template can organize the submission, but its medical explanation must be the clinician’s own supported opinion for that file.
Strategic Considerations for No-Fault Practice
Understanding the distinction between judgment and a triable issue can help both medical providers and their attorneys develop more effective strategies for no-fault practice.
For Medical Providers
Healthcare providers should focus on:
- Investing in proper documentation systems
- Training staff on medical necessity requirements
- Developing relationships with qualified medical reviewers
- Understanding legal precedents and standards
- Maintaining confidence in defending legitimate claims
For Legal Counsel
Attorneys representing medical providers should:
- Stay current with developing case law
- Understand the pattern of successful defenses
- Work with qualified medical experts
- Develop template responses to common LOMN motions
- Educate clients on documentation best practices
Preparing after the motion is denied
Read the order for the issues that remain. Identify the witness who can explain the medical opinion, the records the witness will use, and any foundation objections that the court has not resolved. A successful opposition does not dispense with the proof needed at trial.
The case is therefore useful to both sides. For the provider it illustrates a response sufficient to resist dismissal. For the insurer it explains why an adequate initial report does not guarantee judgment when a competent medical response contradicts it.

What the appellate opinion establishes
Park Slope Medical & Surgical Supply v GEICO was decided on February 14, 2011. The insurer appealed from the denial of its cross-motion for summary judgment. Its two peer reviews were in admissible form and contained a factual basis and medical rationale. The provider’s doctor’s affirmation raised a question requiring trial. The denial of GEICO’s cross-motion was affirmed.
That outcome does not mean the insurer’s reports were boilerplate or defective. The court expressly found the initial medical showing sufficient. Nor did the court grant judgment to the provider. Both motions had been denied, and medical necessity remained for trial.
The original title and Jason’s contemporaneous note reflect a suspicion about the source of the provider’s letter. The opinion does not identify the doctor or print the letter. No conclusion about that author’s involvement should be presented as a judicial finding.
Compare three different procedural outcomes
This note belongs between the insurer-win and insurer-proof-failure cases. In Enko, adequate medical proof went unrebutted. In Amherst, the insurer failed to supply an adequate medical rationale, and the court also found the provider’s response sufficient. Here, both sides supplied evidence, and the conflict required trial.
This comparison is more useful than counting how often a named carrier won or lost. The insurer’s name does not decide whether a report is sufficient. Read the reports, the response and the order before deciding which case addresses the present motion.
What a practitioner can take from the result
When the insurer supplies competent medical evidence, opposition should explain the disagreement using the actual treatment record. The provider does not need to win the medical dispute conclusively at the summary-judgment stage. Evidence creating a genuine dispute can be enough to defeat the motion.
Conversely, a letter that was sufficient in one case is not a reusable guarantee. A prior clinician’s explanation may address a different service, patient condition or criticism. Check whether the response in the current case answers the particular rationale advanced by the reviewer.
CPLR 3212(g) findings deserve separate attention. In this case, the Civil Court had limited trial to medical necessity. A denial of the cross-motion did not reopen every other issue or decide the remaining medical question. Counsel preparing for trial should identify the facts already established by the order.
Historical note: Park Slope illustrates sufficient opposition to an otherwise supported motion, not judicial approval of generic letters. CPLR 3212(b) and (g) distinguish the denial of judgment from the facts fixed for trial.
Build the comparison around the disputed service
A useful opposition can be organized by the reviewer’s actual reason for rejecting the service. If the disagreement concerns the treatment’s purpose, identify where the treating clinician explains that purpose. If it concerns the clinical findings, identify the findings and the clinician’s explanation of their significance. Counsel should not supply a new medical opinion in a memorandum.
Distinguish an unanswered criticism from a disagreement supported by competing evidence. The first can leave a motion unrebutted; the second may create an issue for trial. This distinction explains why Park Slope and the insurer-win notes can reach different results without applying opposite rules.
Do not describe a favorable motion ruling as a finding that the treatment was necessary. The court left that question open. A provider reviewing the result should know whether the next step is trial, further proceedings under the order, or enforcement of an actual judgment. Those outcomes require different preparation.
Keep record foundation separate from medical disagreement
A clinician’s explanation can depend on records supplied by another person. Identify which materials were reviewed and whether the factual assertions relied on can be placed before the court through a proper route. A persuasive clinical account and an admissible evidentiary foundation answer different questions.
The business-records hub organizes those foundation questions. The V.S. Medical trial note is a reminder that a witness’s job title does not establish how claim records were generated.
For purposes of trial preparation, keep the whole medical opinion, not just the portion quoted in opposition. Identify the records which were utilized by the author and note whether the author will be available at trial to testify if needed. Finally, identify the issues that are unresolved as a result of the order. If another issue was resolved under CPLR 3212(g), save that ruling with your trial materials also.
This is also the limit of the archived commentary. Jason’s suspicion about a particular letter explains his reaction to the decision. It does not identify the evidence in a later case or establish that the same form letter would raise a factual dispute there.

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 2,600 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.

A: Respond with a comprehensive medical necessity affirmation that addresses the specific challenges raised and provides detailed medical rationale for the treatment provided.
Q: Are there differences in how medical necessity challenges are handled in different New York counties?
A: While local practice may vary, the legal standards for medical necessity apply uniformly throughout New York State, including Long Island and New York City.
