What Is an Examination Under Oath (EUO) in a No-Fault Pharmacy Case?

James Wong — Founder & Pharmacist, LienScripts | February 22, 2026 | 8 min read

Insurance carriers use Examinations Under Oath to investigate suspected no-fault pharmacy fraud — and refusal to appear is grounds for automatic denial of all pending and future PIP claims. Here's what triggers an EUO request, what happens during one, and how the EUO process affects both the pharmacy's PIP claims and your client's underlying PI case.

What Is an Examination Under Oath?

An Examination Under Oath (EUO) is a formal investigative tool that insurance carriers are permitted to use under New York Insurance Law and New Jersey insurance regulations to investigate potentially fraudulent claims before paying them. It is essentially a sworn deposition — conducted under oath, recorded by a stenographer, and subject to the same consequences for perjury as testimony in court — but it occurs outside of formal litigation, at the carrier's request, as a condition of claim processing.

In the no-fault pharmacy context, EUOs are most commonly directed at two parties:

1. The pharmacy itself — typically the owner or pharmacist-in-charge, asked to appear and answer questions about the pharmacy's business practices, prescriber relationships, patient intake process, and specific billing submissions
2. The patient/claimant — asked to appear and confirm that treatments were actually received, that prescriptions were genuine, and that the patient was actually involved in the accident described in the PIP claim

Insurers use EUOs as both an investigative tool (to build a fraud case) and a procedural trap (to generate a technical basis for denial).

[!KEY] In New York, a PIP claimant or provider that fails to appear for a properly noticed EUO — or fails to appear twice — faces automatic denial of all pending claims and may be precluded from submitting future claims arising from the same accident. Refusal to cooperate with an EUO is not just a risk; it is a bright-line denial trigger under NY Insurance Law § 3420(d) and the governing no-fault regulations.

What Triggers an EUO Request

Insurers don't send EUO notices randomly. The patterns that typically trigger EUO requests in the no-fault pharmacy space include:

Unusual billing concentration: A pharmacy submitting claims concentrated in two or three topical compounds across a large volume of patients attracts insurer fraud units. An EUO allows the carrier to ask the pharmacist-in-charge how prescriptions are received, whether there are referral arrangements with any clinic, and why the formulary is so concentrated.

Suspicious accident circumstances: When the underlying accident has been flagged as potentially staged — multiple claimants from the same vehicle, accident patterns that resemble staging schemes, late-reported accidents — every provider billing for that accident may receive EUO notices.

Prescriber relationship questions: If the insurer has already flagged a nurse practitioner or clinic as part of a steering arrangement, every pharmacy billing for patients from that prescriber/clinic may be swept into EUO investigation.

IME (Independent Medical Examination) results: If an insurer's IME physician has concluded that certain treatments were not medically necessary or not related to the accident, the carrier may send EUOs to providers billing for those treatments to examine the basis for the claimed medical necessity.

High-volume billing from a new provider: A pharmacy that suddenly begins billing large volumes of PIP claims shortly after opening draws scrutiny. EUOs are used to verify that the business is operational and that the billing represents real treatment.

SIU referral: When an insurer's Special Investigations Unit opens a file on a pharmacy, EUOs of the pharmacy and its patients are typically among the first investigative steps.

What Happens During a No-Fault EUO

EUOs in the no-fault context follow a structured process:

Notice requirements: The insurer must provide proper written notice of the EUO to the claimant or provider, specifying the time, date, and location. The notice must be provided with sufficient lead time for the claimant to arrange legal representation.

Who conducts it: EUOs are typically conducted by coverage defense attorneys hired by the insurer — often the same firms that bring RICO suits (e.g., Rivkin Radler for GEICO). The questions are carefully designed to elicit either useful admissions or the kind of inconsistency that can be used to impeach testimony in later litigation.

What is asked of pharmacies:

In a typical pharmacy EUO, the pharmacist-in-charge or owner will be asked:

• How did this patient come to your pharmacy?
• Do you have any referral relationship with any clinic, law firm, or prescriber?
• Do you pay any person or entity in exchange for directing patients to you?
• Do you have any financial arrangement with any prescriber associated with these patients?
• Walk through the specific prescriptions at issue — who prescribed them, how were they received, how were they dispensed?
• How is your formulary determined? Who decides what to stock?
• What is your dispensing protocol for patients involved in auto accidents?
• Do you have a management company, and if so, what services does it provide?

What is asked of patients:

When a patient/claimant is EUO'd about pharmacy claims, typical questions include:

• Were you involved in the accident described in the claim? How did it happen?
• Did you actually receive the medications listed in these prescription records?
• Who referred you to this pharmacy? Did anyone tell you to go there?
• Did you pay anything for these medications? Did you sign any paperwork?
• Did you receive anything of value — cash, gift cards, referral fees — in connection with this accident or treatment?

Recording and transcript: The EUO is transcribed by a court reporter. The transcript is available to the insurer and to the claimant/provider. It can be used as evidence in subsequent litigation — including RICO suits.

EUO Refusal: Automatic Denial Under NY and NJ No-Fault Law

The consequences of failing to appear for an EUO under New York no-fault regulations are severe and well-established:

Under 11 NYCRR 65-3.5(b), a no-fault claimant or provider who fails to appear for a properly scheduled EUO without reasonable justification, or who fails to appear for a rescheduled EUO after one failure, faces denial of all PIP claims arising from the subject accident — including claims already submitted and pending, and claims not yet submitted.

New York courts have consistently upheld EUO non-appearance as a complete defense to PIP claims, even when the underlying medical treatment was legitimate. The policy rationale is that cooperation with the carrier's investigation is a condition precedent to payment, and failure to cooperate voids the claim regardless of its merits.

New Jersey has similar provisions under its PIP regulations, though NJ carriers and courts have been somewhat more flexible about what constitutes adequate justification for non-appearance.

[!KEY] For PI attorneys whose clients are navigating active PIP claims: advise clients about EUO cooperation obligations proactively. A client who ignores an EUO notice — thinking it's optional or adversarial — may lose all PIP benefits and generate a cooperation defense that contaminates the entire PI recovery.

How a Pharmacy EUO Affects the Underlying PI Case

When a pharmacy serving your client is hit with a RICO suit or EUO investigation by a PIP carrier, the consequences can extend to the underlying PI case in several ways:

Prescription records under scrutiny: If the pharmacy's prescription records are subpoenaed in the insurer's litigation, your client's medication history becomes part of that proceeding. Defense counsel in the underlying PI case may become aware of the insurer's fraud allegations and seek to use them to undermine your client's damages claim.

PIP payment disruption: If PIP benefits are suspended during EUO investigation, your client may lose access to PIP-funded medications. This is a reason to have pharmacy lien enrollment in place as a backup.

No-fault denial and underlying tort claim: In auto accident cases, if PIP is denied based on fraud investigation results, the insurer may argue that the denial also undermines the medical necessity of the claimed injuries in the tort case. This is not legally automatic, but defense attorneys will attempt to use it.

Coordination with pharmacy counsel: When a pharmacy partner is under investigation, PI attorneys representing patients who used that pharmacy should monitor the litigation and, if necessary, intervene to protect client interests in the proceeding.

EUOs and Lien-Based Pharmacies

Lien-based pharmacies — including LienScripts-affiliated dispensing pharmacies — are not subject to no-fault EUO processes because they do not bill PIP carriers directly. There is no PIP claim for a carrier to investigate, and therefore no EUO mechanism under the no-fault regulations.

The EUO is a product of the no-fault direct billing relationship between provider and insurer. Remove that billing relationship — as the lien model does — and the EUO exposure goes with it.

This is one of several structural compliance advantages of the lien model for pharmacies and for the attorneys who refer to them.
