Preservation of defenses on NF-10

Another denial that was fatally flawed

By Jason Tenenbaum 8 min read

Key Takeaway

Court finds insurance denial fatally flawed due to incomplete information and incorrect applicant listing, highlighting ongoing issues with denial technicalities in no-fault cases.

This article is part of our ongoing preservation of defenses on nf-10 coverage, with 22 published articles analyzing preservation of defenses on nf-10 issues across New York State. Attorney Jason Tenenbaum brings 24+ years of hands-on experience to this analysis, drawing from his work on more than 1,000 appeals, over 100,000 no-fault cases, and recovery of over $100 million for clients throughout Nassau County, Suffolk County, Queens, Brooklyn, Manhattan, and the Bronx.

When Technicalities Trump Substance: A “Fatally Flawed” Denial

New York’s no-fault insurance system operates under strict procedural requirements that can make or break a claim. Insurance carriers must follow precise rules when denying benefits, and even minor errors can render their denials invalid. This case from the Second Department illustrates how technical defects in denial forms continue to create costly consequences for insurers — and ultimately policyholders.

The dispute centers on fundamental requirements for no-fault insurance denials: carriers must provide complete, accurate information when rejecting claims. When they fail to meet these standards, courts consistently find their denials “fatally flawed,” regardless of whether the underlying claim had merit.

Jason Tenenbaum’s Analysis:

NYU Hosp. for Joint Diseases v Country Wide Ins. Co., 2011 NY Slip Op 04219 (2d Dept. 2011)

“Here, even assuming that the denial of claim form issued by the defendant was timely and was properly mailed to the plaintiff, the form “was fatally defective in that it omitted numerous items of requested information, and thus was incomplete” (Nyack Hosp. v Metropolitan Prop. & Cas. Ins. Co., 16 AD3d at 565; see Westchester Med. Ctr. v New York Cent. Mut. Fire Ins. Co., 81 AD3d 929; compare St. Barnabas Hosp. v Penrac, Inc., 79 AD3d 733). The denial also incorrectly listed Raquel Uviles as the applicant for benefits instead of the plaintiff”

This is just plain ridiculous already. I understand the “specificity rule”, but is there prejudice? Did Henig really not know what was being disclaimed and why? In my mind, enough with these games already. Yes, I know the hospitals in this state are hurting, and the latest budget severely curtailed the medicaid reimbursement rate. But, should the courts impose upon auto insurance policy holders an additional tax because Albany is trying to plug serious budget holes?

Key Takeaway

Technical precision matters more than substance in no-fault denials. Even when carriers have legitimate grounds to deny claims, procedural errors like incomplete forms or incorrect applicant names can invalidate their denials entirely. This creates a system where administrative mistakes can override substantive defenses, potentially increasing costs for all policyholders.


Legal Update (February 2026): Since this 2011 post, New York’s no-fault fee schedules and reimbursement rates have been subject to periodic regulatory updates and amendments. Additionally, procedural requirements for denial forms and preservation of defenses may have been modified through regulatory changes or judicial interpretations. Practitioners should verify current provisions of the Insurance Regulations and applicable fee schedules when analyzing denial form adequacy and reimbursement disputes.

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.

Preservation of Defenses on the NF-10 Denial Form

The NF-10 denial of claim form is the insurer's primary vehicle for asserting defenses to a no-fault claim. Under New York regulations, defenses not raised on the NF-10 within the prescribed time period may be deemed waived. The specificity of the denial, the timeliness of its issuance, and the consequences of failing to properly preserve defenses on the NF-10 are heavily litigated issues. These articles analyze the regulatory requirements and court decisions governing defense preservation on no-fault denial forms.

Common Questions

Frequently Asked Questions

What is an NF-10 form and why does it matter?

The NF-10 is the denial of claim form used by no-fault insurers. Under 11 NYCRR §65-3.8, the insurer must issue the NF-10 within 30 days of receiving proof of claim (or the EUO/IME). The defenses listed on the NF-10 are the only defenses the insurer can raise — any defense not preserved on the form is waived.

What happens if an insurer fails to timely issue an NF-10?

If the insurer does not issue a timely denial via the NF-10, it is precluded from asserting most defenses to the claim. This preclusion doctrine is strictly enforced in New York courts. The claim is then deemed overdue, and the insurer must pay with statutory interest unless it can demonstrate a valid basis for late denial.

Can an insurer raise defenses not listed on the NF-10?

Generally no. The NF-10 must specify the grounds for denial, and the insurer is limited to those grounds in subsequent litigation or arbitration. Certain defenses like lack of coverage or fraud may be raised independently through a declaratory judgment action, but standard claim defenses must be preserved on the NF-10.

“This is just plain ridiculous already. I understand the “specificity rule”, but is there prejudice? Did Henig really not know what was being disclaimed and why? In my mind, enough with these games already.” Yeah like Dan Medical and the case where the Notice to Admit does not get work to admit receipt of the bills wherein an insurance company merely states we mailed every denial so we mailed this one. That doesn’t trouble you. “Yes, I know the hospitals in this state are hurting, and the latest budget severely curtailed the medicaid reimbursement rate. But, should the courts impose upon auto insurance policy holders an additional tax because Albany is trying to plug serious budget holes?” What you really mean is should the courts hurt insurance company profits because insurance companies do not know how to deny a friggin claim. Again I lay down the gauntlet. Get rid of No Fault. Give the citizen his right to sue back. Watch all the freak insurance companies lobby to keep no fault. And what’s with the stupid commercials where the mom get’s caught comitting insurance fraud and the girl crys: “We’re not losers are we.” Yes you are because you got caught. Do it right next time and you’ll be winners. After all the insurance companies are stealing from you with every premium check you send them.

@Ray: How would you feel about a reworking of the rules so that if there’s no serious question that the insurance company got the bills and no serious question that the claimant got the denial, we could just deal with the merits of the claim? Would you consider that fair?
RZ
Raymond Zuppa
Really that’s the way it’s supposed to be Larry. But that does not address the specificity requirement re: the denial. Remember the citizens and tax payers traded their rights to sue moron texters and makeup appliers and guys playing drums to the radio — all while driving. We gave up that right — really the Court took it away from us — so that we would have direct assignment and prompt payment. If you deny you are upsetting the apple cart. Okay sometimes the cart needs to get upset. But you better have a good reason that is well articulated in the document that says you don’t get paid. Geez imagine when I was working at the Robert Plan. If someone gave me a document telling me that I wasn’t getting paid and there was no articulate reason for this — well I would have had to storm the executive section of the building and beat people up … brutally. I mean ugly. I mean like a scene out of a Tarantino movie. But I digress. Oh I turned to the Pit today just for a laugh. It’s over 5000 hits. Now I know there are sites like this one that get that in a day or a week. But nothing has been done there. I think this means that there is a demand for the pit. I am almost done with some stuff and then the Pit is going viral.

Larry Rogak
One of the few benefits of getting old is that you get to be around long enough to gain perspective. Before no-fault turned into “big business” — the late 1990s — insurers rarely issued denials. Why? Because insurers rarely received medical bills that were questionable. After an MVA there was maybe an ER visit, and in serious cases, a hospital stay or surgery. You know, the kind of bills that seem perfectly reasonable under the circumstances. Even when victims trying to build up a BI case did their 90 days of chiro treatment, those rarely got denied. But when 20 unrelated people spill out of a Volkswagen and go directly to “Dox In A Box” for daily regimens of chiro, acu, PT, massage, psych — that’s why you get denials. Because treatment like that doesn’t pass the sniff test. Ok, having said that… let the abuse begin.

Raymond Zuppa
Couldn’t agree with you more. Bro I was the only prosecutor making jump-ins do time in Kings County. Before me they used to get a non criminal dispostion and a parade from the Court House back to their neighborhood. But I will say that the Insurance Companies have used the fraud issue to hurt legitimate policyholders and claimants. I have seen it personally and sued for it. And the endless commercials. They are making a ton off of no fault in New York. Again let us be rid of No Fault.

Here we go again. Blanket denials fundamentally contradict No-Fault law because the insurer is required to consider each claim irrespective of its pronouncement that it will no longer consider claims for the patient prospectively (see 30-day rule, 11 NYCRR 65-3.8). “When a provider of medical services [first] submits a claim as assignee of an insured, neither the statute nor the regulations contemplate the insurer simply sitting mute and failing to act upon the claim, silently and secretly relying upon an earlier [blanket] denial issued directly to the insured” (A&S Medical, 789 N.Y.S.2d at 29, quoting Atlantis Med. v. Liberty Mut. Ins. Co., 2002 N.Y. Slip. Op. 40043U [Dist. Ct. Nassau County 2002]). Under JT’s notion that blanket denials are legally sufficient, when the applicant provides indisputable information in a subsequent proof of claim that refutes the insurer’s blanket denial (for example, by proving-up attendance at a medial examination the failure of which to attend was the basis for the blanket denial), the insurer can merely hide behind its blanket denial as its justification for failing to process the new claim. In short, the use of blanket denials provides a built-in excuse for the insurer to refuse to evaluate No-Fault claims on their respective merits, which directly conflicts with No-Fault law. Further, under JT’s notion that blanket denials are proper, the insurer may issue multiple blanket denials, none of them referencing a specific claim, and pick and chose its defense at trial from any of those included in any individual form. JT’s concept contradicts No-Fault law and policy because it (1) entitles insurers to hide inappropriate carrier conduct behind vague denials of claims; (2) creates uncertainty regarding which denials applies to which claims; (3) allows the insurer to surprise the first-party applicant regarding which defense it will rely on in court; (4) makes it difficult or impossible for the applicant to evaluate the insurer’s defense(s) thereby necessitating more No-Fault actions and less settlements. In contrast, it there is no burden for the carrier to simply identify the claim which the denial pertains to. Even in a failure to attend medical examination context the carrier should be required to identify the claim, since there are instances where the carrier issues a denial permised upon non attendance and thereafter goes ahead and holds the assignor’s medical examination. In fact, that’s what happened in Unitrin. All told, if we are discussing regs that should be judicially eliminated (somehow), how about the 45 day rule? Clearly, such a rule does more to eliminate valid claims for medical care reimbursement then acts as a hedge to claim fraud. This is especially the case with the new policy condition requirements. Anything can be vetted in the verification process, including by virtue of EUO, IME, and sworn statement conditions, so the idea that there must also be a 45 day claim submission deadline as well is bogus.

Okay. I will respond to this rant over the weekend, and probably put this all in the main blog area. This has been a ridiculously long week, and I do not have enough brain cells at this moment to respond.

In the meantime, we can mull over this, from the new york post today regarding ins. broker Waldorf’s fraudulent sale, for 15 years, of IP insurance as standard State regulated insurance. The brokers sold it to schools, non profits, etc. The SID just reached what is now called a “Sweetheart” deal regarding this 15 years of fraud. Page 33, “Sin of Commission” “The [SID] said that the matter was “a taxation case, not a disciplinary one. Helping the firm win a hush-hush settlement at the end of a 16-month state probe was former Dept. Of Ins. Superintendent Greg Serio, now managing Director at former US Sen. Al D’Amato’s Park Strategies lobby firm. Serio, who also runs his own lobbying firm, Albany based Compass Company Consultants, was hired by the Waldorfs for damage control… Serio, an appointee of Gov Pataki ran the [SID] from 2001-2004, and for a decade before that headed its legal department, supervising some of the employees who handed the Waldorf probe, sources say. A copy of the settlement was obtained by the post through a [FOIL] request on April 5. The document, however, wasn’t even signed until April 12, a week after it was requested… One state official said ‘This raises a lot of questions about what’s going on in the department….'”
S
Sun
In sum, this is some very cozy hi-jinks that is going on at the SID. Waldorf is still a licensed broker after 15 years of behavior that can only be characterized as fraud, after it hired Serio’s lobbying firm. Moreover, the “future” dated settlement agreement implies that a new settlement document was generated for the sake of public disclosure. This infers a sort of direct connection between regulator and regulated, both acting as one entity to hide and confuse facts.
RZ
Raymond Zuppa
Yeah … tell me about it. If you recall I sued the Superintendent. Every Court up through the Court of Appeals defended them by saying — they can do what they want. Translated: the insurance industry can do what they want. Why? The Court’s are political. Politics is money. The insurance industry has dumped so much money into New York State and Federal politics that it shames God himself.
LR
Larry Rogak
Apparently my own blog has cooties: hardly anyone posts on it except for an occasional spambot. Maybe I’m better off; it takes time to moderate posts. Anyway I have been counseling against issuing blanket denials for years. They have no legal effect and can only work against the carrier.

JT Author
Larry, Personally, I liked the Rogak report when you sent the live cases to our emails. I know you still do that for the non no-fault cases. While I try to read every appellate case that comes out – including family, criminal and sometimes Surrogates Court – I always miss stuff. So, your report comes in handy in those instances.

Raymond Zuppa
J.T. you are a zealous advocate for your clients. I personally hate facing you because you fight so hard. And that’s the bottom line. I promise the Pit will be active in two weeks with totally uncensored comments. I hope to be visciously attacked personally so that I may respond even more visciously. And remember no one here including yourself has made more brazen statements that are anti piggie provider including insults aimed at piggie provider attorneys. The only thing that disgusts me more then some insurance company conduct — not all insurance companies and not all conduct — is the piggie provider. Famous is my stance against knock out chiropractic — also called Chiropractic Under Anesthesia (usually cheap vodka that they put on a wad of paper towels and place on the patient’s face and nose)

Understanding New York Preservation of defenses on NF-10 Law

New York has a unique legal landscape that affects how preservation of defenses on nf-10 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 preservation of defenses on nf-10 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. Whether you need representation in a no-fault arbitration, a personal injury trial, an employment discrimination hearing, or an appeal to the Appellate Division, the Law Office of Jason Tenenbaum, P.C. brings $24+ years of real courtroom experience to your case. 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.
