Understanding Severance Requirements in No-Fault Insurance Cases

The landscape of no-fault insurance litigation has evolved significantly, particularly regarding when courts will sever claims involving multiple accidents. A recent appellate decision has clarified the specific evidence required for severance, moving beyond the simple fact that claims arose from different accident dates. This development has important implications for how courts evaluate severance motions and whether denying such motions without proper evidence constitutes an abuse of discretion.

The key issue revolves around what documentation defendants must present to justify separating claims, particularly when dealing with multiple vehicle accidents occurring on different dates. Understanding these requirements is crucial for both providers seeking payment and insurance companies defending against no-fault insurance claims.

Severance represents a procedural mechanism allowing courts to separate joined claims into distinct actions when judicial economy or fairness considerations warrant separation. In no-fault litigation, providers frequently join multiple claims involving different assignors or different accidents into single lawsuits to reduce filing fees and streamline litigation. Insurance carriers often seek to sever these consolidated claims, arguing that separate claims involving distinct accidents should be litigated separately.

Case Background: Unique Physical Therapy v. Global Liberty Insurance

Unique Physical Therapy, PT, P.C. v Global Liberty Ins. Co. of N.Y., 2021 NY Slip Op 50323(U)(App. Term 2d Dept. 2021)

In Unique Physical Therapy, the defendant insurance carrier moved to sever multiple no-fault claims that the plaintiff provider had consolidated into a single lawsuit. The claims arose from different motor vehicle accidents that occurred on different dates and involved different assignors (injured parties). The defendant argued that these factual differences warranted severance because each claim involved distinct accidents, different claimants, and separate factual circumstances.

The trial court denied the severance motion, finding that the defendant had not presented sufficient evidence justifying separation of the claims. The insurance carrier appealed this determination, citing the case of Premier Surgical Services, P.C. v GEICO General Insurance Co., which the carrier interpreted as establishing that severance is warranted whenever no-fault claims arise from multiple car accidents on different dates.

The Appellate Term needed to clarify whether different accident dates alone justify severance or whether additional evidence is required. The court’s analysis focused on what the Premier Surgical decision actually held and what evidence that case’s record contained beyond merely different accident dates.

The Appellate Term examined the complete record from Premier Surgical and discovered that the decision had been based on more than just different accident dates. The Premier case involved claims where the denial of each claim was based on specific assignors’ failures to appear for scheduled independent medical examinations (IMEs). While this critical fact had been omitted from the published decision, it was the actual basis for the court’s determination that severance was appropriate.

Jason Tenenbaum’s Analysis

“To the extent that defendant cites Premier Surgical Servs., P.C. v GEICO Gen. Ins. Co. (65 Misc 3d 140, 2019 NY Slip Op 51704 ) to support the opposite conclusion, it should not be relied upon for the proposition that severance is warranted solely on the ground that no-fault claims arose out of multiple car accidents on different dates. The record in Premier demonstrated that the denial of each claim was based on the particular assignor’s failure to appear for scheduled independent medical examinations and, while omitted from the decision, that fact was the basis for this court’s determination.”

So now you see the post 2016 formula necessary to obtain severance. Does this mean that when a Defendant does not present this proof and the court severs the claims, that is now an abuse of discretion?

The Unique Physical Therapy decision establishes that severance in no-fault cases requires individualized proof specific to each claim, not merely evidence that claims arose from different accidents. This holding prevents insurance carriers from obtaining automatic severance based solely on the fact that consolidated claims involve multiple accidents or assignors.

The court’s clarification of Premier Surgical reveals an important principle about precedential interpretation. Courts must look beyond published language to understand what evidence actually supported prior decisions. When practitioners cite cases for broad propositions, opposing counsel and courts should examine whether the cited decisions actually rested on those broad principles or whether the outcomes depended on specific factual circumstances.

The decision also reflects judicial concerns about potential abuse of severance motions. If carriers could obtain severance simply by identifying different accident dates, they could force providers to pursue separate lawsuits for each claim, substantially increasing litigation costs and potentially rendering some claims economically infeasible to pursue. This would tip the balance too far in favor of insurance companies and against healthcare providers’ legitimate reimbursement interests.

The ruling creates a framework requiring defendants to demonstrate claim-specific reasons justifying severance. These reasons might include different assignors’ failures to appear for examinations, distinct defenses applicable to different claims, or other individualized circumstances making joint litigation inappropriate or prejudicial. The mere existence of multiple accidents, without more, does not satisfy this requirement.

Jason Tenenbaum’s question about whether granting severance without proper proof constitutes an abuse of discretion raises an important procedural issue. If appellate courts have now established that severance requires specific individualized proof, trial courts that grant severance motions lacking such proof may be exceeding their discretion. This could provide grounds for appellate relief when carriers obtain severance without presenting the required evidence.

Practical Implications for Insurance Carriers and Providers

Courts now require specific evidence beyond multiple accident dates to justify severance in no-fault cases. The decision clarifies that defendants must demonstrate individual circumstances for each claim denial, such as failure to appear for examinations, rather than relying solely on different accident dates. This raises questions about whether granting severance without such proof constitutes an abuse of discretion.

For insurance carriers, this ruling means severance motions must be supported by detailed evidence explaining why each claim involves distinct circumstances warranting separate litigation. Carriers should identify claim-specific defenses, such as individual assignors’ failures to cooperate with examination requests, verification non-compliance affecting particular claims, or other circumstances unique to specific claims. Generic arguments that different accidents warrant severance will no longer suffice.

Carriers should also recognize that the strategic value of severance motions has diminished. If severance requires substantial individualized proof, the effort and expense of preparing such proof may outweigh any benefits from separating claims. Carriers may need to reevaluate whether pursuing severance makes economic sense in cases where all claims involve similar defenses or where preparing individualized evidence would be burdensome.

Healthcare providers opposing severance motions should carefully examine defendants’ supporting evidence to determine whether it contains the required claim-specific information. Providers should challenge severance motions that rest solely on different accident dates or multiple assignors without demonstrating individualized circumstances justifying separation. The Unique Physical Therapy decision provides strong precedential support for opposing such inadequately supported motions.

Providers should also consider the strategic implications of the ruling. When planning litigation, providers might more confidently consolidate multiple claims into single lawsuits, knowing that defendants face higher evidentiary burdens to obtain severance. This consolidation can reduce filing fees, streamline discovery, and make litigation more economically viable, particularly for smaller claims that might not justify separate lawsuits.

Key Takeaway

Severance in no-fault insurance litigation requires claim-specific evidence demonstrating individualized circumstances that justify separating consolidated claims, not merely proof that claims arose from different accidents on different dates. Insurance carriers must present evidence of distinct defenses, such as specific assignors’ failures to appear for examinations, rather than relying on accident date differences alone. This evidentiary requirement protects healthcare providers from having to pursue economically inefficient separate litigation for each claim and ensures that severance serves legitimate judicial economy or fairness objectives rather than carrier litigation strategy.

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 severance in New York civil litigation?

Severance under CPLR 603 separates claims or parties into independent actions for trial. Courts may order severance when claims involve different factual or legal issues that would confuse the jury, or when trying them together would be prejudicial to one party.

When will a court grant a motion to sever claims?

Courts consider whether the claims share common questions of law or fact, whether severance would promote judicial efficiency, and whether joinder would prejudice any party. In personal injury cases, severance of liability and damages trials is common.

What is the difference between severance and bifurcation?

Severance creates separate independent actions, while bifurcation splits a single action into separate trials (typically liability and damages). Bifurcation under CPLR 603 keeps the case as one action but tries issues separately, which is common in personal injury cases on Long Island.

The standard for severance is basically whatever the judge feels like doing. I often combine a few cases together as it keeps costs down and often makes it easier to settle in the long term. Currently only one firm ever has a problem with it….

There is an irony in this. In no-fault states such as Massachusetts and Florida, they try to avoid joining cases because that kills the attorney fee. In NY, joined cases actually increase the attorney fee.

Understanding New York Severence Law

New York has a unique legal landscape that affects how severence 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 severence 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.

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.
