Why Conclusory Affidavits Fail: Building Strong Opposition to Medical Necessity Summary Judgment Motions

When insurance companies challenge the medical necessity of treatments provided to car accident victims, they often file summary judgment motions seeking complete dismissal of no-fault claims. For medical providers throughout Long Island and New York City, the key to defeating these motions lies in submitting detailed, specific evidence that directly addresses and rebuts the insurance company’s arguments.

Unfortunately, many medical practices make the critical error of submitting conclusory affidavits that fail to meaningfully address the insurance company’s evidence, resulting in devastating losses that could have been avoided with proper legal strategy and preparation.

At Jason Tenenbaum New York Law, we’ve successfully defended hundreds of medical providers against these aggressive insurance company tactics throughout Nassau County, Suffolk County, and the five boroughs of New York City. Our comprehensive approach to summary judgment opposition ensures that your practice has the best possible chance of defeating these challenges and recovering the compensation owed for legitimate medical services.

Understanding Medical Necessity Summary Judgment Motions

Summary judgment is a powerful legal tool that allows courts to resolve cases without a trial when there are no genuine issues of material fact in dispute. Insurance companies frequently use summary judgment motions to challenge the medical necessity of treatments provided to accident victims, arguing that the services were not required or were excessive.

To succeed on a summary judgment motion, the insurance company must demonstrate that no reasonable jury could find in favor of the medical provider based on the evidence presented. Typically, they do this by submitting Independent Medical Examination (IME) reports from their own experts who conclude that the treatment in question was not medically necessary.

The Burden-Shifting Framework

Summary judgment motions operate under a burden-shifting framework:

  1. The moving party (insurance company) must make a prima facie showing that they are entitled to judgment as a matter of law
  2. If successful, the burden shifts to the non-moving party (medical provider) to demonstrate that genuine issues of material fact exist
  3. The non-moving party must present evidence that creates a triable issue of fact, not merely conclusory allegations

This framework means that medical providers cannot simply rest on their pleadings or submit vague, general statements about medical necessity. They must present specific, detailed evidence that directly contradicts the insurance company’s experts.

Case Analysis: Eastern Star Acupuncture v. Mercury Insurance Co.

Eastern Star Acupuncture, P.C. v Mercury Ins. Co., 2010 NY Slip Op 50380(U)(App. Term 2d Dept. 2010)

“In support of its motion for summary judgment, defendant submitted an affidavit executed by the chiropractor/acupuncturist who had performed an independent medical examination (IME), as well as an affirmed IME report, establishing, prima facie, a lack of medical necessity for the services at issue. In opposition to defendant’s motion, plaintiff failed to raise a triable issue of fact. Contrary to the finding of the Civil Court, the affirmation of plaintiff’s “supervising acupuncturist” did not meaningfully refer to, let alone rebut, the conclusions set forth in the IME report (see Pan Chiropractic, P.C. v Mercury Ins. Co., 24 Misc 3d 136, 2009 NY Slip Op 51495 ; see also Innovative Chiropractic, P.C. v Mercury Ins. Co., 25 Misc 3d 137, 2009 NY Slip Op 52321 ). Accordingly, so much of defendant’s motion as sought dismissal of the claims at issue should have been granted (id.; see also A. Khodadadi Radiology, P.C. v NY Cent. Mut. Fire Ins. Co., 16 Misc 3d 131, 2007 NY Slip Op 51342 ).”

The Critical Failure: Lack of Meaningful Rebuttal

The Eastern Star Acupuncture case perfectly illustrates the most common mistake medical providers make when opposing summary judgment motions. The practice submitted an affirmation from their supervising acupuncturist, but this affirmation failed to “meaningfully refer to, let alone rebut, the conclusions set forth in the IME report.”

This failure was fatal to their case. Even though they had a medical professional willing to support the necessity of their treatment, their affirmation was too general and conclusory to create a genuine issue of material fact for trial.

The Pattern of Similar Failures

The court cited several other cases with identical outcomes, demonstrating that this is a widespread problem affecting medical providers across New York:

  • Pan Chiropractic, P.C. v Mercury Ins. Co. – Another case where conclusory opposition failed to defeat summary judgment
  • Innovative Chiropractic, P.C. v Mercury Ins. Co. – Similar failure to meaningfully rebut IME conclusions
  • A. Khodadadi Radiology, P.C. v NY Central Mutual Fire Ins. Co. – Established the principle that general affirmations are insufficient

This pattern shows that New York courts consistently require specific, detailed opposition that directly addresses the insurance company’s evidence.

What Makes an Affidavit “Conclusory”?

Understanding what courts consider “conclusory” is crucial for medical providers seeking to defeat summary judgment motions. An affidavit is considered conclusory when it:

Fails to Address Specific Criticisms

If the insurance company’s IME report identifies specific problems with the treatment (e.g., excessive frequency, inappropriate modalities, lack of objective findings), the opposing affidavit must address each of these criticisms specifically.

Contains Only General Statements

Statements like “the treatment was medically necessary” or “the patient required ongoing care” are insufficient without detailed explanation of why the treatment was necessary and how it related to the patient’s condition.

Lacks Supporting Medical Rationale

Courts expect medical professionals to provide the scientific or clinical reasoning behind their conclusions, not just their ultimate opinion.

Ignores Contradictory Evidence

An effective affidavit must acknowledge and explain any contradictory evidence or findings in the medical records.

Provides No Timeline or Progression Analysis

For ongoing treatments, the affidavit should explain the patient’s progression and why continued treatment remained necessary over time.

Elements of Effective Summary Judgment Opposition

To successfully defeat medical necessity summary judgment motions, medical providers must submit opposition that includes several key elements:

Point-by-Point Rebuttal

Every conclusion in the insurance company’s IME report must be specifically addressed. If the IME doctor says treatment was excessive, explain exactly why it was not. If they question the diagnostic findings, provide detailed support for those findings.

Clinical Justification

Provide detailed medical reasoning for each aspect of treatment, including:

  • Initial diagnostic impressions and objective findings
  • Treatment goals and expected outcomes
  • Patient response to treatment
  • Reasons for continuing or modifying treatment plans
  • Relevant medical literature or treatment guidelines

Timeline Analysis

For cases involving ongoing treatment, provide a detailed timeline showing:

  • Patient’s condition at various points in treatment
  • Specific improvements or setbacks
  • Rationale for treatment modifications
  • Justification for treatment duration

Credentialing and Experience

Establish the qualifications and experience of the medical professional providing the opposition affidavit, particularly in treating similar conditions.

Common Mistakes That Lead to Summary Judgment

Based on our extensive experience defending medical providers against summary judgment motions, several common mistakes repeatedly lead to unsuccessful opposition:

Using template affidavits that don’t specifically address the unique facts and criticisms in each case is a recipe for failure.

Inadequate Medical Record Review

Affidavit authors who haven’t thoroughly reviewed all relevant medical records often miss crucial supporting evidence.

Failure to Address Weaknesses

Ignoring apparent weaknesses in the treatment records rather than addressing them head-on often results in summary judgment for the insurance company.

Late or Rushed Preparation

Summary judgment deadlines are strict. Rushed preparation often results in inadequate opposition that fails to address key issues.

Wrong Expert

Having an expert outside their area of expertise submit an affidavit can undermine the entire opposition.

The Strategic Importance of Early Case Assessment

The key to successful summary judgment opposition often lies in early case assessment and preparation:

Identify Potential Vulnerabilities

Review treatment records early to identify areas that insurance companies are likely to challenge, allowing for proactive evidence gathering.

Develop Supporting Documentation

Gather additional supporting evidence such as diagnostic studies, progress notes, and patient testimonials that strengthen the case.

Expert Witness Selection

Identify and retain qualified experts early in the process, ensuring they have adequate time to thoroughly review records and prepare comprehensive opinions.

Discovery Strategy

Use discovery tools to obtain additional evidence supporting medical necessity and to challenge the insurance company’s experts.

The Role of Expert Medical Testimony

In most cases involving complex medical necessity challenges, expert medical testimony is essential for successful summary judgment opposition:

Independent Review

Independent experts can provide objective analysis of treatment records and medical necessity without the appearance of bias that may affect treating physicians.

Specialized Knowledge

Experts in specific fields can provide detailed analysis based on current medical literature and accepted treatment protocols.

Credibility

Well-qualified experts with impressive credentials can effectively counter insurance company IME doctors.

Educational Value

Expert affidavits can educate judges about complex medical concepts and treatment rationales.

Long Island and NYC Litigation Considerations

Medical providers in the New York metropolitan area face unique challenges in summary judgment opposition:

High Case Volume

The high volume of no-fault cases in Nassau County, Suffolk County, and New York City means that courts may have less time to carefully review opposition papers, making it even more important that they be clear and compelling.

Experienced Defense Counsel

Insurance companies often employ skilled defense attorneys who are experts at crafting summary judgment motions that exploit common weaknesses in medical provider cases.

Judicial Familiarity

Local judges are very familiar with medical necessity standards and are quick to spot conclusory or inadequate opposition.

Cost Pressures

The high cost of litigation in the New York area puts pressure on medical providers to resolve cases quickly, sometimes leading to inadequate opposition preparation.

The Financial Impact of Summary Judgment Losses

The consequences of losing summary judgment motions can be devastating for medical practices:

Complete Loss of Recovery

Summary judgment typically results in dismissal of the entire claim, meaning no recovery for services that may have been entirely appropriate.

Fee Shifting

In some cases, practices may be required to pay the insurance company’s attorney fees and costs.

Precedential Effect

Losses can establish negative precedents that affect future cases involving the same practice.

Reputation Impact

Repeated summary judgment losses can damage a practice’s reputation and relationships with other healthcare providers.

Best Practices for Medical Providers

To maximize your chances of successfully opposing summary judgment motions, consider these best practices:

Maintain Detailed Records

Comprehensive, detailed treatment records provide the foundation for effective summary judgment opposition.

Document Patient Progress

Regular progress notes that document objective improvements help justify ongoing treatment.

Consult with experienced no-fault litigation attorneys as soon as you receive notice of a summary judgment motion.

Expert Relationships

Develop relationships with qualified medical experts who can review cases and provide detailed opinions when needed.

Stay Current

Keep up with current medical literature and treatment protocols to support the necessity of your treatment approaches.
