Triable Issue of Fact as to Submission of a No-Fault Claim: Mailing Affidavit vs. Non-Receipt Defense

Key Takeaways

• A carrier’s prima facie proof of non-receipt of a claim form can be rebutted by a mailing affidavit from the provider’s side, creating a triable issue of fact that defeats summary judgment.
• Under CPLR 3212, summary judgment is denied whenever the papers reveal a genuine factual dispute requiring a trial — here, whether the claim form was ever submitted.
• Untimely submission of a claim form, by itself, does not entitle the carrier to summary judgment dismissing the complaint.
• Both sides win or lose these motions on the quality of their mailing and claims-intake affidavits, not on the merits of the underlying treatment.

No-fault insurance disputes often center on whether required documentation was properly submitted to insurance carriers. When carriers claim they never received claim forms, the burden shifts between parties depending on the evidence presented. The case of Lenox Hill Radiology v Great Northern Insurance Co. illustrates how courts handle these non receipt scenarios and why procedural defenses may not always succeed.

This appellate decision demonstrates that insurance companies cannot simply deny receipt without considering contrary evidence from healthcare providers. The court’s analysis reveals important principles about burden of proof and the limitations of certain procedural defenses in no-fault litigation.

The Decision

Jason Tenenbaum’s Analysis:

Lenox Hill Radiology v Great N. Ins. Co., 2016 NY Slip Op 50206(U)(App. Term 2d Dept. 2016)

(1) “While defendant made a prima facie showing that it had not received plaintiff’s claim form, the affidavit of the mailing supervisor in plaintiff’s attorneys’ offices established that the claim at issue had been mailed to defendant. Thus, a triable issue of fact exists as to the submission of the claim form”

(2) “Moreover, contrary to defendant’s contention, even if plaintiff failed to submit the claim form in a timely manner, untimely submission, in and of itself does not entitle defendant to summary judgment dismissing the complaint”

I am confused as to why this was appealed, or why an insurance carrier paid money to appeal this? Could someone enlighten me here?

The Legal Framework: Triable Issues of Fact and Proof of Mailing

A “triable issue of fact” is the standard that controls every summary judgment motion in New York. Under CPLR 3212, the movant must tender admissible evidence eliminating any material question of fact; if the opposing papers raise a genuine factual dispute, the motion must be denied and the issue goes to trial. The court does not weigh credibility on a summary judgment motion — it only decides whether a real dispute exists.

In no-fault litigation, the submission-of-the-claim battleground is fought entirely with mailing proof. New York recognizes a presumption of receipt where a party proves either actual mailing or a standard office practice and procedure designed to ensure that items are properly addressed and mailed. The same body of mailing and proof-of-service law governs both sides: carriers use it to prove denials and verification requests went out, and providers use it to prove bills were sent.

That symmetry decided this case. The carrier’s claims affidavit established prima facie non-receipt of the bill. But the mailing supervisor in the provider’s attorneys’ offices swore the claim had been mailed. With sworn proof of mailing on one side and sworn proof of non-receipt on the other, neither account could be rejected as a matter of law — a classic triable issue of fact.

The Second Holding: Untimeliness Alone Is Not a Silver Bullet

The Appellate Term’s second point is just as practical. The no-fault regulations require claims to be submitted within a prescribed period after treatment, and late submission is a real defense — but it is a defense that must be asserted and proven through a timely denial on that ground, not a self-executing bar. The court held that untimely submission, “in and of itself,” does not entitle the carrier to summary judgment dismissing the complaint.

For carriers, this means a late-bill argument raised for the first time on motion papers, untethered from the claim-handling record, will not carry a dismissal. For providers, it means a late submission is a problem to be litigated — potentially excusable or waived — not an automatic forfeiture.

Why This Matters for Carriers and Providers

For carriers, the decision is a reminder that a non-receipt affidavit only wins when it goes unanswered. Before moving for summary judgment on non-receipt, defense counsel should anticipate a responsive mailing affidavit and evaluate whether the motion will accomplish anything beyond fixing a trial issue.

For medical providers, the case shows the value of a disciplined mailing practice — whether in the billing office or in collection counsel’s office. An affidavit from the person who actually mailed the claim, or who supervises a standard mailing procedure, is what keeps the complaint alive.

For everyone, the author’s closing question remains fair: an appeal over whether a factual dispute exists is an expensive way to learn that a factual dispute exists.

Practice Pointers

• Providers: keep contemporaneous mailing logs and identify, by name and role, the person who can swear to the office mailing practice. Generic, boilerplate affidavits draw scrutiny.
• Carriers: if the defense is late submission, deny on that ground within the regulatory timeframe and build the motion on the denial — do not rely on untimeliness as a freestanding dismissal argument.
• Both sides: dueling sworn accounts of mailing and non-receipt almost always produce a denial of summary judgment. Budget for trial accordingly.

Frequently Asked Questions

What is a triable issue of fact?

A triable issue of fact is a genuine, material factual dispute that cannot be resolved on papers alone. Under CPLR 3212, if the parties’ admissible evidence points in conflicting directions on a fact that matters to the outcome, summary judgment must be denied and the dispute resolved at trial.

How does a medical provider prove a no-fault claim form was submitted?

Through proof of mailing: an affidavit from someone with personal knowledge of the actual mailing, or from someone who can describe a standard office practice designed to ensure proper addressing and mailing. That proof creates a presumption of receipt that the carrier’s bare denial cannot erase.

Does late submission of a no-fault claim automatically get the case dismissed?

No. As Lenox Hill Radiology holds, untimely submission in and of itself does not entitle the carrier to summary judgment. Timeliness is a defense that must be properly asserted and proven, and it can be contested like any other issue in the case.
