Background

American Transit Insurance Company (the insurer) denied no-fault insurance benefits to Beach Medical Rehabilitation, P.C. (the medical provider), which had submitted claims on behalf of its assignor, Marissa Hirsch, for medical services arising from a motor vehicle accident. The medical provider proceeded to arbitration and won a principal award of $5,772.62. The insurer appealed to a master arbitrator, who affirmed the award in February 2022. Rather than pay, the insurer then commenced an action in Supreme Court, Kings County, under Insurance Law § 5106(c)—a provision that permits an insurer that has lost before a master arbitrator to seek a “de novo” court determination of the underlying no-fault dispute—and sought declaratory judgment that it had no obligation to pay the benefits.

The medical provider cross-moved for summary judgment, seeking dismissal of the complaint, a declaration that the insurer was obligated to pay, confirmation of the master arbitration award, and an award of attorneys’ fees. The Supreme Court denied the medical provider’s motion. The medical provider appealed.

The Court’s Holding

The Appellate Division reversed and granted the medical provider’s motion in its entirety. The court’s analysis turned on two independent preclusion doctrines applicable in New York no-fault insurance litigation.

First, the court found that the insurer failed to raise a triable issue of fact as to its timely denial of the medical provider’s submitted claims. In a no-fault action, a claimant makes its prima facie case by demonstrating that prescribed billing forms were mailed to and received by the carrier and that payment was overdue. The insurer must then produce evidence of a timely denial. Here, the insurer submitted affidavits of two employees—but neither employee established personal knowledge of a standard office procedure for properly addressing and mailing denial-of-claim forms, nor of the actual mailing in this particular case. Without that evidentiary predicate, the insurer could not demonstrate timely denial. Under New York no-fault law, an insurer that fails to timely deny a claim is “generally precluded” from asserting defenses against payment, except in the narrow case of a “lack of coverage” defense. Because no coverage defense was at issue here, the insurer was precluded from asserting medical necessity as a defense.

Second, the court considered whether the insurer could separately defend on lack of causation—a defense that, unlike medical necessity, is not extinguished by an untimely denial under New York law. The insurer submitted a peer review affidavit from a physician, but that affidavit was fatally deficient: it did not reflect review of the assignor’s full medical records (including records of conservative treatment predating the EMG/NCV test at issue), did not address the treating physician’s clinical reasoning for ordering the test, and did not address other treatments encompassed within the submitted claims. The peer review physician also failed to specifically analyze the causal connection between the assignor’s alleged injuries and the accident. That deficiency in the peer review record, the court held, meant the insurer failed to raise a triable issue on causation as well. The medical provider was therefore entitled to summary judgment, confirmation of the master arbitration award, and an award of reasonable attorneys’ fees under Insurance Law § 5106(a), to be determined on remand.

Key Takeaways

  • An insurer seeking to defend a no-fault de novo action under Insurance Law § 5106(c) must independently establish its timely denial with employee affidavits showing personal knowledge of the specific mailing or of a standard office procedure for proper addressing and mailing—generalized or conclusory affidavits will not carry the burden.
  • An untimely denial precludes all defenses except “lack of coverage”; medical necessity remains unavailable as a defense even in a de novo court proceeding where the denial was not timely established.
  • A peer review affidavit on the causation defense must address the full medical record, the treating physician’s clinical reasoning, all treatments included in the submitted claims, and the specific causal nexus between the injuries and the accident—piecemeal or incomplete peer review fails to raise a triable issue.
  • When the medical provider prevails in the de novo action, it is entitled to confirmation of the master arbitration award plus attorneys’ fees under Insurance Law § 5106(a) and 11 NYCRR 65-4.10(j)(4).

Why It Matters

American Transit Insurance Company has been among the most litigious no-fault insurers in New York, regularly exercising its right to seek de novo court determinations after losing at arbitration. This decision demonstrates the peril of that strategy: an insurer that fails to establish timely denial with proper affidavits in the de novo proceeding, and whose peer review is too narrow to address the full scope of treatment or causation, risks not only losing the de novo case but also being compelled to pay attorneys’ fees on top of the original award. For medical providers and their counsel, the decision reinforces that summary judgment is available in de novo proceedings once the claimant establishes mailing and overdue payment and the insurer cannot demonstrate timely denial—the same no-fault preclusion rules that apply in direct payment actions apply equally here. For insurers, the message is that peer review must be comprehensive: it cannot pick and choose which records to review or which treatments to address.
