The Etienne Standard’s Impact on Prima Facie Cases

The Second Department’s landmark decision in Viviane Etienne Medical Care, P.C. v. Country-Wide Insurance Co. fundamentally altered the landscape for establishing prima facie cases in no-fault litigation. Before Etienne, some courts had adopted an extremely lenient standard articulated in cases like Mary Immaculate Hospital v. Allstate Insurance Co., which suggested that providers could establish their prima facie burden by merely showing that more than 30 days had elapsed without payment. The Etienne decision rejected this minimalist approach and required providers to address verification requests in their prima facie showing.

The case of Westchester Medical Center v. Allstate Insurance Co. represents one of the first applications of the Etienne standard by the Second Department. This decision clarifies what evidence providers must submit to establish a prima facie case when insurers have sent verification requests, and demonstrates how the Etienne framework differs from the earlier Mary Immaculate approach that some practitioners hoped would continue to govern.

The significance of this evolution cannot be overstated. Under the old Mary Immaculate standard, providers could prevail on summary judgment with minimal evidentiary submissions. Etienne imposed meaningful burdens on providers to demonstrate either compliance with verification requests or the invalidity of such requests—a requirement that has reshaped litigation strategy for both providers and insurers.

Case Background

In Westchester Medical Center v. Allstate Insurance Co., the plaintiff hospital sought to recover no-fault benefits as assignee of Paul Knable. Allstate defended on grounds that the hospital had not responded to verification requests, thereby tolling the 30-day payment period indefinitely pursuant to Insurance Law § 5106(a).

The hospital moved for summary judgment, submitting evidence that it had filed proper claim forms and that more than 30 days had elapsed without payment. Allstate opposed, arguing that the plaintiff had failed to establish a prima facie case because it had not addressed whether verification requests were sent or whether the hospital had complied with such requests.

The lower court denied the hospital’s motion, and the plaintiff appealed to the Second Department. The central issue on appeal was whether the Etienne decision—decided shortly before—required the hospital to affirmatively prove compliance with verification requests or their absence as part of its prima facie case, or whether the insurer bore the burden of proving verification non-compliance as an affirmative defense.

Jason Tenenbaum’s Analysis:

Westchester Med. Ctr. v Allstate Ins. Co., 2013 NY Slip Op 08616 (2d Dept. 2013)

“Contrary to the primary argument advanced by the defendant insurance company, the plaintiff Westchester Medical Center, as assignee of Paul Knable (hereinafter the hospital), made a prima facie showing of entitlement to judgment as a matter of law on the first cause of action (see Viviane Etienne Medical Care, P.C., as assignee of Alem Cardenas v Country-Wide Ins. Co., _______ AD3d _______ ). In opposition, the defendant failed to raise a triable issue of fact as to whether, after receiving the hospital’s NF-5 claim form, the 30-day period within which to pay, deny, or seek verification of the no-fault claim was extended or tolled indefinitely due to the hospital’s failure to comply with a certain request for verification.”

I am thinking Plaintiff presented the billing affidavit of one of its affiants who either said the he submitted the entire medical records of the hospital or that he never received any verification requests. This is different from Mary Immaculate v. Allstate and Amaze v. Eagle days where all the affiant had to say was that more than 30-days elapsed and payment in full has not been made. I think the plaintiff bar was hoping Etienne would do that, but that is not the case. If a prima facie case made its way to other 3 departments, would they hold true to Mary Immaculate v. Allstate (which they are currently following) or would they follow Etienne, which continues to incorporate an Ave T. v. Auto One analysis?

The Second Department’s decision in Westchester Medical Center establishes that the Etienne standard requires providers to address verification issues in their prima facie showing, but does not necessarily require extensive proof. The court’s statement that the hospital “made a prima facie showing” suggests that the plaintiff submitted affidavit testimony regarding either submission of medical records or non-receipt of verification requests—evidence that goes beyond the minimal showing permitted under Mary Immaculate.

This interpretation of Etienne creates a middle ground between the extremely lenient Mary Immaculate standard and an onerous requirement that providers produce comprehensive documentation of all communications with insurers. Providers must affirmatively address verification in their moving papers, but can satisfy this burden through affidavits stating that records were submitted or that no verification requests were received.

The court’s further statement that Allstate “failed to raise a triable issue of fact” regarding verification compliance suggests that insurers cannot defeat summary judgment with mere assertions that verification requests were sent. Instead, insurers must produce admissible evidence—typically proof of mailing coupled with verification request copies—demonstrating that requests were sent and remain outstanding. This burden-shifting framework protects providers from unsubstantiated verification defenses.

Jason Tenenbaum’s analysis highlights a critical question: will other Appellate Division departments follow Etienne, or will they adhere to their own precedents like Mary Immaculate? The First, Third, and Fourth Departments had developed their own approaches to prima facie cases before Etienne was decided. While the Second Department’s decisions carry persuasive authority, they do not bind other departments unless adopted or until addressed by the Court of Appeals.

The reference to “Ave T. v. Auto One analysis” in Jason Tenenbaum’s commentary suggests that Etienne incorporates principles from earlier Second Department cases that required providers to demonstrate either compliance with verification requests or the impropriety of such requests. This analytical framework differs significantly from Mary Immaculate, which essentially ignored verification issues at the prima facie stage and treated them purely as affirmative defenses for insurers to prove.

Practical Implications

For medical providers, Westchester Medical Center clarifies that summary judgment motions must include affidavit testimony addressing verification requests. At a minimum, providers should submit affidavits from billing personnel stating either: (1) that all requested medical records were provided to the insurer, or (2) that no verification requests were received. This relatively modest evidentiary requirement should not prove burdensome for providers with adequate record-keeping systems.

Providers should avoid relying on Mary Immaculate-style affidavits that merely recite that 30 days elapsed without payment. While such affidavits may remain sufficient in the First, Third, or Fourth Departments, Second Department practitioners must incorporate verification-related testimony. Failure to do so will result in denial of summary judgment motions even when claims are meritorious.

For insurance carriers, the decision confirms that verification defenses require substantiation through admissible evidence. Insurers cannot defeat provider motions by simply asserting in attorney affirmations that verification requests were sent. Instead, insurers must submit proof of mailing (typically through CPLR 4518(a) affidavits) and copies of the verification requests themselves. This evidentiary requirement prevents insurers from raising verification defenses as litigation tactics without factual support.

The divergence among Appellate Divisions regarding prima facie standards creates strategic considerations for both sides. When possible, parties may want to consider how choice of forum affects the applicable prima facie standard. However, venue rules typically constrain forum selection to the assignor’s residence or the defendant’s principal place of business, limiting strategic venue choices in most cases.


Legal Update (February 2026): The standards for establishing prima facie cases in no-fault insurance claims may have evolved since this 2013 decision, particularly regarding verification request procedures and the burden of proof requirements under Insurance Law Section 5106. Practitioners should verify current provisions in the Insurance Regulations and recent appellate decisions, as the Department of Financial Services may have amended verification protocols and related procedural requirements.

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.

Common Questions

Frequently Asked Questions

What is additional verification in no-fault insurance?

Additional verification is a request by the insurer for more information to process a no-fault claim, authorized under 11 NYCRR §65-3.5. When the insurer sends a verification request, the 30-day clock for claim processing is tolled (paused) until the requested information is received. This is a common insurer tactic to delay payment — but the verification request must be timely and relevant to be valid.

How long does an insurer have to request additional verification?

Under the no-fault regulations, the insurer must request initial verification within 15 business days of receiving the claim. Follow-up verification requests must be made within 10 business days of receiving a response to the prior request. If the insurer fails to meet these deadlines, the verification request is invalid and cannot be used to toll the claim processing period.

What types of additional verification can a no-fault insurer request?

Under 11 NYCRR §65-3.5, insurers may request medical records, provider licensing documentation, proof of treatment rendered, tax returns or financial records (in certain fraud investigations), authorization for release of medical records, and signed NF-3 verification forms. The verification request must be relevant to the claim and not overly burdensome. Requests for information not reasonably related to claim processing may be challenged as improper.

What happens if I don't respond to a no-fault verification request?

Failure to respond to a timely and proper verification request can result in denial of your no-fault claim. Under 11 NYCRR §65-3.5(o), if the requested verification is not provided within 120 calendar days of the initial request, the claim is deemed denied. The 120-day period runs from the date of the original request. However, if the verification request itself was untimely or improper, the denial based on non-response may be challenged.

What does 'prima facie case' mean in no-fault litigation?

In no-fault litigation, the provider or claimant bears the initial burden of establishing a prima facie case by submitting proof of the claim — including evidence that the services were provided, the claim was timely submitted, and the amount billed is correct. Once the prima facie case is established, the burden shifts to the insurer to demonstrate a valid defense, such as medical necessity denial, lack of coverage, or failure to appear for an EUO or IME.

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.
