Lack of causation not established on a peer review

The Stringent Requirements for Causation Defenses in No-Fault Litigation

Causation represents one of the most powerful defenses available to insurance carriers in no-fault litigation. When a carrier can demonstrate that an injury or treatment bears no causal relationship to the motor vehicle accident, it may deny coverage for the related medical services. However, establishing lack of causation requires more than a conclusory statement from a peer review physician. The reviewing doctor must conduct a thorough analysis, consider all relevant medical records, and provide internally consistent reasoning to support the causation opinion.

New York courts have developed strict standards governing causation opinions in the no-fault context. A peer review or IME report containing contradictory statements about causation fails to establish the prima facie case necessary to support a denial. Similarly, when a reviewing physician fails to examine critical medical records—such as MRI reports or operative reports—the causation analysis may be deemed deficient. These requirements ensure that causation denials rest on solid medical foundations rather than superficial or incomplete reviews.

The case of Shur v Unitrin Advantage Ins. Co. illustrates how courts scrutinize peer review causation opinions, particularly when those opinions concern surgical interventions. When an IME doctor opines that surgery was not causally related to an accident, courts examine whether the doctor reviewed all pertinent medical documentation and whether the opinion contains internal contradictions that undermine its reliability.

Case Background

Shur v Unitrin Advantage Ins. Co., 2017 NY Slip Op 51011(U)(App. Term 2d Dept. 2017)

“Here, the affirmed report of the doctor who had performed an independent medical examination (IME) of the assignor contained contradictory statements (see e.g. Black v County of Dutchess, 87 AD3d 1097; Coscia v 938 Trading Corp., 283 AD2d 538 ) as to whether the injury to plaintiff’s assignor’s right knee was “partially causally related to” the accident at issue or caused by “preexisting degenerative changes.” Furthermore, an MRI report that was reviewed by the IME doctor did not set forth an impression of degenerative changes. Nor did the IME doctor indicate that he had examined an operative report on the arthroscopy at issue. Thus, contrary to the determination of the District Court, defendant failed to make a prima facie showing of lack of causation. Consequently, defendant’s motion should have been denied.”

The above raise two issues: examination of operative report and examination of the MRI report play. Both of these documents play a critical role in whether a peer doctor’s causation analysis (who opines that surgery is not related to the accident) is valid. I sense a lot of causation peer reviews will not survive the Vladamir Shur test.

Legal Analysis: The Vladamir Shur Test for Causation Opinions

The Appellate Term’s decision in Shur establishes clear requirements for peer review causation opinions, creating what Jason Tenenbaum aptly calls “the Vladamir Shur test.” This test encompasses two critical components: internal consistency of the causation opinion and completeness of the medical record review.

First, the court found fatal contradictions in the IME doctor’s causation analysis. The report alternately stated that the right knee injury was “partially causally related to” the accident and that it was caused by “preexisting degenerative changes.” These contradictory statements prevented the defendant from establishing a prima facie case of lack of causation. When an expert’s opinion wavers between finding partial causation and attributing the injury entirely to pre-existing conditions, the opinion lacks the clarity and consistency necessary to support a coverage denial. This internal contradiction alone proved sufficient to defeat the defendant’s motion.

Second, and perhaps more significantly, the court identified critical deficiencies in the IME doctor’s record review. The MRI report reviewed by the IME doctor did not document degenerative changes, yet the doctor attributed the injury to such changes. This inconsistency between the objective imaging findings and the doctor’s conclusions raised serious questions about the reliability of the causation opinion.

Even more problematic, the IME doctor failed to indicate that he had examined the operative report from the arthroscopy procedure. When opining that a surgical procedure was not causally related to an accident, reviewing the operative report represents a foundational step in the analysis. The operative report documents what the surgeon found during the procedure, the specific pathology addressed, and the surgical interventions performed. Without reviewing this critical document, a peer reviewer lacks the factual foundation necessary to render an informed opinion about whether the surgery addressed accident-related pathology or pre-existing conditions.

The court’s emphasis on these documentary deficiencies establishes that peer reviewers must examine all relevant medical records before rendering causation opinions. Superficial reviews that fail to consider key diagnostic imaging or surgical reports will not satisfy the carrier’s burden of establishing lack of causation.

Practical Implications: Reviewing the Vladamir Shur Test

As Jason Tenenbaum presciently observed, this decision suggests that “a lot of causation peer reviews will not survive the Vladamir Shur test.” His observation proves particularly apt for peer reviews that opine on surgical causation without thoroughly examining operative reports and diagnostic imaging.

For insurance carriers and peer review physicians, this case underscores the importance of comprehensive record review. Before concluding that surgery was not causally related to an accident, the reviewing physician must:

1. Obtain and review all relevant MRI reports and other diagnostic imaging studies
2. Examine operative reports documenting what pathology was found and addressed during surgery
3. Ensure consistency between objective imaging findings and causation conclusions
4. Avoid contradictory statements that undermine the opinion’s reliability
5. Clearly articulate the basis for attributing findings to pre-existing conditions rather than accident-related trauma

For providers and plaintiffs’ attorneys, the Vladamir Shur test provides a roadmap for challenging deficient causation opinions. When opposing summary judgment motions based on lack of causation, counsel should scrutinize the peer review for:

1. Internal contradictions in the causation analysis
2. Failure to review operative reports
3. Inconsistencies between imaging findings and the peer reviewer’s conclusions
4. Gaps in the record review that undermine the opinion’s foundation
5. Conclusory statements unsupported by specific medical findings

The fact that this peer review was conducted by Dr. Thomas Nipper—a physician whose reports appear frequently in no-fault litigation—demonstrates that even experienced peer reviewers can produce deficient causation opinions when the analysis lacks thoroughness or contains contradictions. The lesson extends beyond any individual reviewer: causation opinions must rest on complete record review and internally consistent reasoning, regardless of the reviewer’s credentials or experience.

This decision also highlights the heightened scrutiny courts apply to causation denials for surgical procedures. Surgery typically occurs only after conservative treatment proves inadequate and objective findings support the need for intervention. When a peer reviewer challenges surgical causation without thoroughly examining what the surgeon found and addressed during the procedure, courts will likely find the opinion insufficient to establish lack of causation.

The requirement that peer reviewers examine operative reports makes practical and medical sense. The operative report provides contemporaneous documentation of the pathology addressed during surgery, often revealing findings not apparent on pre-operative imaging. A surgeon who performs arthroscopy and documents damaged cartilage, torn ligaments, or other traumatic pathology provides evidence of accident-related injury that a peer reviewer cannot credibly dispute without examining that documentation.

Finally, the decision emphasizes that contradictory causation opinions fail as a matter of law. An opinion that finds “partial” causal relationship while simultaneously attributing injury to pre-existing degenerative changes speaks from both sides of its mouth. Such contradictions prevent defendants from establishing the prima facie case necessary to shift the burden to plaintiffs, resulting in denial of summary judgment motions.
