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.

First Aid Occupational Therapy, PLLC v Country-Wide Ins. Co., 2010 NY Slip Op 50149(U)(App. Term 2d Dept. 2010)

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).”

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.

Legal Update (February 2026): Since this 2010 decision, New York’s no-fault fee schedules have undergone multiple revisions and the regulatory framework governing medical billing practices and expert testimony requirements may have been substantially modified. Practitioners should verify current fee schedule provisions, expert affidavit standards, and procedural requirements for unbundling defenses under the most recent Insurance Department regulations and case law developments.

Legal Context

Why This Matters for Your Case

New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.

Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

Understanding New York Additional Verification Law

New York has a unique legal landscape that affects how additional verification cases are litigated and resolved. The state's court system includes the Civil Court (for claims up to $25,000), the Supreme Court (the primary trial court for unlimited jurisdiction), the Appellate Term (which hears appeals from lower courts), the Appellate Division (divided into four Departments, with the Second Department covering Long Island, Brooklyn, Queens, Staten Island, and several upstate counties), and the Court of Appeals (the state's highest court). Each court has its own procedural requirements, local rules, and case-assignment practices that can significantly impact the outcome of your case.

For additional verification matters on Long Island, cases are typically filed in Nassau County Supreme Court (at the courthouse in Mineola) or Suffolk County Supreme Court (in Riverhead). No-fault arbitrations are heard through the American Arbitration Association, which assigns arbitrators throughout the metropolitan area. Workers' compensation claims go to the Workers' Compensation Board, with hearings at district offices across the state. Understanding which forum is appropriate for your case — and the specific procedural rules that apply — is essential for a successful outcome.

The procedural landscape in New York also includes important timing requirements that can affect your case. Most civil actions are subject to statutes of limitations ranging from one year (for intentional torts and claims against municipalities) to six years (for contract actions). Personal injury cases generally have a three-year deadline under CPLR 214(5), while medical malpractice claims must be filed within two and a half years under CPLR 214-a. No-fault insurance claims have their own regulatory deadlines, including 30-day filing requirements for applications and 45-day deadlines for provider claims. Understanding and complying with these deadlines is critical — missing a filing deadline can permanently bar your claim, regardless of how strong your case may be on the merits.

Attorney Jason Tenenbaum regularly practices in all of these venues. His office at 326 Walt Whitman Road, Suite C, Huntington Station, NY 11746, is centrally located on Long Island, providing convenient access to courts and offices throughout Nassau County, Suffolk County, and New York City.

If you have questions about the legal issues discussed in this article, call (516) 750-0595 for a free, no-obligation consultation.

New York's substantive law also presents distinct challenges. In motor vehicle cases, the no-fault system under Insurance Law Article 51 provides first-party benefits regardless of fault, but limits the right to sue for non-economic damages unless the plaintiff establishes a "serious injury" under one of nine statutory categories. This threshold — codified at Insurance Law Section 5102(d) — requires medical evidence showing more than a minor or subjective injury, and courts have developed detailed standards for each category. Fractures must be documented through imaging studies. Claims of permanent consequential limitation or significant limitation of use require quantified range-of-motion testing with comparison to norms. The 90/180-day category demands proof that the plaintiff was unable to perform substantially all of their usual daily activities for at least 90 of the 180 days following the accident.

In employment discrimination cases, the legal standards vary depending on whether the claim arises under state or local law. The New York State Human Rights Law employs a burden-shifting framework: the plaintiff must first establish a prima facie case by showing membership in a protected class, qualification for the position, an adverse employment action, and circumstances giving rise to an inference of discrimination. The burden then shifts to the employer to articulate a legitimate, non-discriminatory reason for its decision. If the employer meets this burden, the plaintiff must demonstrate that the stated reason is pretextual. The New York City Human Rights Law, by contrast, applies a broader standard, asking whether the plaintiff was treated less well than other employees because of a protected characteristic.
