Defense of unbundling requires coding expert affidavit

Understanding Medical Billing Unbundling in New York No-Fault Insurance

New York’s no-fault insurance system presents unique challenges for both healthcare providers and insurance carriers, particularly when it comes to medical billing practices and expert testimony requirements. For legal professionals practicing in Long Island and New York City, understanding the intricacies of unbundling defenses has become increasingly critical in today’s complex insurance landscape.

Case Analysis: First Aid Occupational Therapy, PLLC v Country-Wide Ins. Co.

Unbundling. I love this word. I discussed this issue in a previous post. The only difference between the previous case and this case is that the penalty for failing to proffer an expert affidavit (assuming you can find an expert who would support the unbundling theory in this case) is succumbing to a plaintiff’s summary judgment motion. The relevant portions of the case are as follows:

“While defendant denied the claims underlying plaintiff’s first and fifth causes of action on the ground that plaintiff sought to recover in excess of the fee schedule by ” unbundling’ the service into … separate bill” even though such services “are considered part of the initial medical evaluation,” defendant did not submit an affidavit from someone with sufficient expertise to establish that ground as a matter of law or even to demonstrate the existence of a triable issue of fact with respect to the billing for such services (see Zuckerman v City of New York, 49 NY2d 557 ; Kingsbrook Jewish Med. Ctr. v Allstate Ins. Co., 61 AD3d 13 ). As a result, defendant “failed to raise a triable issue of fact in admissible evidentiary form sufficient to warrant denial of summary judgment in favor of on the cause of action” (Kingsbrook Jewish Med. Ctr., 61 AD3d at 23).”

The Critical Role of Expert Affidavits in Unbundling Defense

The court’s decision in First Aid Occupational Therapy underscores a fundamental principle in New York no-fault litigation: insurance carriers cannot simply assert unbundling as a defense without proper evidentiary support. The requirement for expert testimony in medical billing disputes reflects the technical nature of medical coding and the need for qualified professionals to explain complex billing practices to the court.

For insurance defense attorneys working throughout Long Island and New York City, this case serves as a stark reminder that procedural requirements cannot be overlooked, regardless of how strong the underlying defense may appear. The failure to submit a proper expert affidavit can result in an automatic loss on summary judgment, regardless of the merits of the unbundling claim.

Verification Requests and Timing Issues

Finally, the case involved a premature additional verification request where plaintiff was granted summary judgment. This was reversed.

“It is undisputed that defendant timely mailed its initial requests for verification and that plaintiff failed to provide the information requested. Plaintiff also did not provide the information requested in defendant’s follow-up verification requests, which were mailed on the 30th day after the initial verification requests but prior to the expiration of the full 30-day period within which plaintiff was supposed to respond to defendant’s initial requests for verification. As the foregoing facts are nearly identical to those in Infinity Health Prods., Ltd. v Eveready Ins. Co. (67 AD3d 862 ), “the 30-day period within which the defendant was required to pay or deny the claim did not commence to run … plaintiff’s action is premature” (id. at 865).”

Strategic Implications for Legal Practice

The First Aid Occupational Therapy decision provides several key takeaways for legal practitioners handling no-fault cases in the New York metropolitan area:

Expert Witness Selection

When defending against alleged unbundling, carriers must retain qualified experts who can speak to medical coding standards and industry practices. These experts must be able to articulate why specific services should be considered bundled under applicable fee schedules and provide detailed analysis of the billing practices in question.

Timing Considerations in Verification Requests

The case also highlights the importance of proper timing in verification requests. Carriers must be careful not to send premature follow-up verification requests before the initial 30-day period expires, as this can create procedural complications that may benefit the plaintiff.

Practical Applications for NYC and Long Island Practitioners

For attorneys representing healthcare providers or insurance carriers in the New York area, this case emphasizes the need for meticulous case preparation and expert witness coordination. The technical nature of medical billing requires specialized knowledge that courts will not accept without proper foundation.

Building a Strong Unbundling Defense

Insurance carriers seeking to defend against unbundling claims should consider the following approach:

• Early identification and retention of qualified medical coding experts
• Comprehensive review of billing records and applicable fee schedules
• Detailed analysis of industry standards and practices
• Proper timing of all verification and discovery requests

Frequently Asked Questions

What is medical billing unbundling?

Unbundling refers to the practice of billing separately for medical services that should be billed together as a single comprehensive service under applicable fee schedules. This can result in higher reimbursement than would be appropriate for the actual services provided.

Why do insurance carriers need expert affidavits to defend unbundling claims?

Medical coding and billing practices are technical subjects that require specialized knowledge. Courts need qualified experts to explain industry standards, fee schedule requirements, and proper billing practices to determine whether unbundling has occurred.

What qualifications should an expert have for unbundling cases?

Experts should have extensive experience in medical coding, billing practices, and knowledge of New York no-fault fee schedules. They should be able to provide detailed analysis of specific billing practices and industry standards.

How can timing issues affect verification requests?

Sending follow-up verification requests before the initial 30-day response period expires can create procedural complications. Carriers should wait for the full 30-day period to expire before sending additional requests.
