For chiropractors treating patients injured in motor vehicle accidents, an EUO no-fault New York request can quickly turn routine billing into a serious legal risk. An Examination Under Oath (EUO) is part of the insurance carrier’s verification process, and failing to handle it correctly can jeopardize large portions of a practice’s receivables.

 

Because New York courts treat EUO compliance as a condition precedent to coverage, missed or mishandled EUOs can lead to widespread claim denials, sometimes affecting tens or even hundreds of thousands of dollars in unpaid bills.

 

What Triggers an EUO Request?

Under New York’s no-fault regulations, insurers can request additional verification of a claim, and one form of verification is an Examination Under Oath.

For chiropractors, EUO requests often arise when insurers believe certain billing patterns require closer review. These may include:

• High volumes of similar treatments across multiple patients
• Repeated accident patients referred from the same sources
• Questions about ownership or management of the practice
• Concerns about potential overutilization or billing irregularities

Once EUO notices begin arriving, it often signals that the insurer is scrutinizing not just a single claim but the broader claim activity associated with the practice.

Under the regulations, insurers generally must follow specific procedures when requesting an EUO. This typically includes:

• Requesting additional verification within 15 business days of receiving the claim
• Sending follow-up notices if the verification request goes unanswered
• Advising that claims may be denied if verification is not provided within 120 days

What Happens If You Don’t Appear?

New York courts and the Department of Financial Services have made clear that appearing for a properly requested EUO is a condition precedent to the insurer’s obligation to pay no-fault benefits .

If the provider or injured party fails to appear for properly scheduled EUOs, insurers may issue denials based on noncompliance with policy conditions.

For chiropractors, this can lead to significant consequences, including:

• Denial of all bills tied to the affected claim number
• Use of the nonappearance as a defense in arbitration or litigation
• Potential inclusion in broader declaratory judgment actions involving multiple claims

Courts have upheld EUO-based denials when insurers demonstrate that they:

• Properly mailed at least two EUO scheduling letters
• Provided reasonable notice of the examination date
• Recorded that no appearance occurred on the scheduled dates
• Issued a denial within the required timeframe after the second nonappearance

Because these disputes often hinge on technical procedural details, they frequently become the subject of arbitration or court proceedings.

 

Can Carriers Schedule Multiple EUOs?

New York’s no-fault regulations allow insurers to request examinations “as reasonably necessary” to verify claims. In some situations, this means multiple EUOs may be scheduled during an investigation. 

For example, an insurer might:

• Conduct an EUO of the injured patient first
• Later request an EUO of the treating chiropractor
• Request an EUO of the professional corporation if ownership questions arise

However, these requests must still be reasonable and connected to legitimate claim verification.

Courts have criticized insurers that issue repeated EUO requests simply to delay payment or prolong investigations without advancing the inquiry. When EUO demands become excessive or abusive, they may be subject to legal challenge.

For chiropractic offices managing high volumes of no-fault claims, tracking EUO notices carefully by claim number, patient, and entity can help determine whether a request is truly new or simply a rescheduling of a prior examination.

 

Are EUOs Really Mandatory?

In New York no-fault cases, an EUO is not merely a request, but is typically considered a contractual and regulatory obligation when properly invoked.

Insurance policies commonly require insured parties and assignees to submit to EUOs when requested as part of the claim verification process. Courts have repeatedly held that failure to comply with this requirement may constitute a material breach of the policy , which can prevent recovery of benefits.

In practical terms, chiropractors should not assume that an EUO notice can safely be ignored or indefinitely postponed.

Even when a provider believes the request is unnecessary, refusing to appear may undermine the ability to challenge the EUO later. Addressing the request promptly and strategically is often the safest course.

 

When an EUO Request May Be Improper

While EUOs are a legitimate investigative tool, insurers must still comply with the no-fault verification rules.

Legal challenges to EUO-based denials often focus on procedural issues such as:

Timeliness and verification procedure

• Whether the EUO request was issued within the required verification timeframe
• Whether proper follow-up notices were sent
• Whether the insurer warned that claims could be denied after 120 days of noncompliance

Mailing and notice

• Whether scheduling letters were mailed to the correct address
• Whether the insurer can prove mailing through office procedures or logs
• Whether reasonable advance notice of the EUO was provided

Scope and reasonableness

• Whether multiple EUO requests were reasonably necessary
• Whether the request was used primarily to delay payment
• Whether the questioning extends beyond legitimate claim verification

Because these disputes often involve detailed procedural arguments, chiropractors facing EUO requests frequently benefit from legal guidance early in the process.

Protecting Your Practice When EUO Requests Begin

For many chiropractic offices, the first EUO request is the earliest sign that an insurer is preparing to challenge claims more aggressively. Practical steps may include:

• Consulting a no-fault litigation attorney in New York when EUO notices are directed at the practice or its owners
• Keeping detailed records of all communications, scheduling letters, and adjournment requests
• Evaluating whether denials based on EUO nonappearance can be challenged in arbitration or court

Many providers assume an EUO is just a formality. In reality, it can determine whether your entire claim portfolio survives. A pattern of EUO nonappearances can give insurers a powerful defense that may shut down $100,000 or more in receivables tied to no-fault claims.

 

Because EUO disputes are one of the most common reasons insurers deny chiropractic no-fault claims in New York, practices that receive repeated EUO notices should take the issue seriously.
