Evidence insufficient to prove that provider complied with verification request

A third-party biller’s affidavit did not adequately show that the provider sent its verification response in Pomona Medical Diagnostic v Praetorian. The problem was the affidavit’s foundation, not a rule forbidding biller testimony or requiring an eyewitness to every envelope.

Historical note: Pomona rejected the affidavit presented, not the office-practice method of proving mailing. Delta Diagnostic Radiology, 17 Misc 3d 16, expressly recognizes that method. See the current verification guide for later claims-processing rules.

Last reviewed: September 2026. Original publication date retained.

Why the response affidavit was insufficient

The Appellate Term, First Department, decided Pomona on October 28, 2013. Praetorian had made a prima facie showing that its verification letters were timely and properly mailed. Pomona opposed the insurer’s cross-motion with an affidavit from an employee of a third-party billing company.

The employee lacked personal knowledge of the date on which the purported verification-compliance letter was mailed. She also described the office’s mailing practices only in general terms. Together, those deficiencies left the provider without evidence sufficient to raise a triable issue. The court reversed the denial of Praetorian’s cross-motion and dismissed the claim as premature.

That is the narrow holding. The opinion does not describe the biller’s workload, say that the provider lost its records, or find that the employee knowingly made a false statement. Nor does it identify the employee’s lack of an eyewitness memory as a categorical bar to proof through office practice.

Jason’s original comment below compares this discussion with mailing evidence in MVAIC independent-medical-examination cases. That is an observation about a shared evidence problem. Pomona itself was a verification-response case, not an IME no-show decision.

Actual mailing and office practice are alternative routes

The Delta Diagnostic Radiology decision states the distinction directly: mailing can be established through personal knowledge of the mailing or through a standard office practice designed to ensure proper addressing and mailing. The affiant need not say that ensuring compliance was personally the affiant’s duty.

An eyewitness-only reading would be too broad. A detailed, adequately grounded account of the office routine can support the mailing presumption. Pomona’s description was insufficiently specific to do that job.

For a billing company, the useful questions concern how the witness knows the process and how it works: identifying the claim, matching attachments, checking the address, preparing the outgoing package and handing it off for mailing. Not every case requires identical evidence. The testimony should describe the actual system, including any records on which the witness relies.

A saved letter is not the whole transmission record

Keep the response and what accompanied it together. If the file contains only a cover letter, the lawyer reviewing it may be unable to determine which records were enclosed. If the biller and provider keep different systems, identify how the submission moved from one to the other.

A dated copy can show what was prepared. It does not necessarily establish when it entered the mail. A mailing log can address dispatch, but may need a connection to the particular claim or packet. A receipt can show delivery without identifying every enclosure. The pieces should be evaluated together rather than treated as interchangeable proof.

This is practical recordkeeping guidance, not a new evidentiary rule announced in Pomona. It is equally unhelpful to assume that outsourced billing is inherently unreliable or that using certified mail automatically resolves every issue.

Compare the result with the related cases

Darlington Medical Diagnostics concerns a denial of receiving the carrier’s request. Pomona concerns whether the provider proved sending its response. The person who handles incoming requests may know little about how responses are dispatched.

In Compas v Praetorian, an owner’s affidavit did raise a factual dispute about response mailing on one cause of action. The published decision does not reproduce enough of that affidavit to justify saying that no mailing details were required.

Completeness is another question. Compas v Travelers addresses a partial response; New Horizon Surgical Center addresses a missing informed-consent form referred to in the provider’s own exhibits. Good mailing proof would not, by itself, establish that an omitted item was supplied.

Applying the old note to an electronic file

For a modern file, distinguish a scan of an old mailing from a record of electronic transmission. Retain the source documents and whatever transmission information the actual system generates. Do not describe a paper-mailing opinion as automatically validating email service or a portal upload.

The remote-practice archive explains why working from a laptop does not change that distinction. The Sound Shore timeline illustrates another: the carrier’s receipt of the initial claim papers is separate from its receipt of later verification.

Finally, a current dispute requires the applicable verification regulation, not just a quotation from an older mailing case. Pomona did not decide the later Chapa denial-timing issue.

When the provider and biller hold different parts of the record

A provider may retain the medical documents while a billing company prepares the cover letter and dispatches the response. In that arrangement, the person who assembled the records may know their contents but not when the packet was mailed. The person who mailed it may know the dispatch procedure but not how the medical records were selected.

Before drafting an affidavit, identify those responsibilities and locate the records connecting them. A transfer to the biller, the biller’s assembled packet and its outgoing correspondence record describe separate steps. If an attachment was added after the initial transfer, make that sequence clear rather than assuming every saved copy is identical.

This is an illustrative workflow, not a description of Pomona’s business. The published opinion does not explain how its biller received the materials. The point is to avoid asking one witness to make an unsupported statement about another person’s work. Where the actual routine supplies the mailing foundation, describe that routine accurately and identify the witness’s familiarity with it.

Original commentary preserved from the archive

What is noteworthy here is that the same discussion that the Court gives to the MVAIC IME no-show mailing cases is given here to Pomona.
