OPINION OF THE COURT
Graffeo, J.In this action, a hospital seeks to recover no-fault insurance benefits for services rendered to a patient injured in a motor vehicle accident. We conclude that the insurance company’s failure to timely request verification of the patient’s assignment of benefits to the hospital precludes the carrier from now contesting the validity of the assignment. We therefore affirm the order of the Appellate Division so holding.
Plaintiff New York and Presbyterian Hospital treated patient Browne in 2004 for injuries he sustained as a result of an automobile accident. At the time of the accident, Browne had an automobile insurance policy with defendant Travelers Property Casualty Insurance Company affording him first-party no-fault coverage. In October 2004, the hospital, through its contract billing agent—Hospital Receivables Systems, Inc.—sought payment of $24,344.96 from Travelers for services provided to Browne. The billing agent sent Travelers a hospital facility form (NYS Form NF-5), a UB-92 form and an assignment of benefits form (NYS Form NF-AOB). The assignment portion of the NYS Form NF-5 and the assignment of benefits form both indicated that Browne’s signature was “on file,” but neither form displayed his actual signature.
Travelers did not reject the forms or request verification of the assignment. After Travelers failed to pay or deny the claim within 30 days of its receipt, the hospital commenced this action against Travelers and Farmington Casualty Company (an affiliated carrier) for payment of its bill as well as statutory interest and attorneys’ fees under Insurance Law § 5106 (a).1 In its answer, Travelers raised as an affirmative defense the lack of a valid assignment between Browne and the hospital.
Both parties moved for summary judgment and Supreme Court granted the hospital’s motion and directed entry of judg*317ment against Travelers in the amount of $24,344.96 plus statutory interest and attorneys’ fees. The court held that Travelers’ failure to timely contest any deficiency in the assignment documents precluded the carrier from raising the issue in this proceeding. The Appellate Division affirmed and we granted Travelers leave to appeal.
New York’s no-fault automobile insurance system is designed “to ensure prompt compensation for losses incurred by accident victims without regard to fault or negligence, to reduce the burden on the courts and to provide substantial premium savings to New York motorists” (Matter of Medical Socy. of State of N.Y. v Serio, 100 NY2d 854, 860 [2003]). In furtherance of these goals, the Superintendent of Insurance has adopted regulations implementing the No-Fault Law (Insurance Law art 51), including circumscribed time frames for claim procedures.
These regulations require an accident victim to submit a notice of claim to the insurer as soon as practicable and no later than 30 days after an accident (see 11 NYCRR 65-1.1, 65-2.4 [b]). Next, the injured party or the assignee (typically a hospital, as in the case here) must submit proof of claim for medical treatment no later than 45 days after services are rendered (see 11 NYCRR 65-1.1, 65-2.4 [c]).2 3Upon receipt of one or more of the prescribed verification forms used to establish proof of claim, such as the NYS Form NF-5, an insurer has 15 business days within which to request “any additional verification required by the insurer to establish proof of claim” (11 NYCRR 65-3.5 [b]).3 An insurer may also request “the original assignment or authorization to pay benefits form to establish proof of claim” within this time frame (11 NYCRR 65-3.11 [c]). Significantly, an insurance company must pay or deny the claim within 30 calendar days after receipt of the proof of claim (see Insurance Law § 5106 [a]; 11 NYCRR 65-3.8 [c]). If an insurer seeks additional verification, however, the 30-day window is tolled until it receives the relevant information requested (see 11 NYCRR 65-3.8 [a] [1]).
An insurer’s failure to pay or deny a claim within 30 days carries substantial consequences. By statute, overdue payments *318earn monthly interest at a rate of two percent and entitle a claimant to reasonable attorneys’ fees incurred in securing payment of a valid claim (see Insurance Law § 5106 [a]). More importantly, a carrier that fails to deny a claim within the 30-day period is generally precluded from asserting a defense against payment of the claim (see Presbyterian Hosp. in City of N.Y. v Maryland Cas. Co., 90 NY2d 274, 282 [1997], rearg denied 90 NY2d 937 [1997]). This Court has recognized a narrow exception to this preclusion remedy for situations where an insurance company raises a defense of lack of coverage (see Central Gen. Hosp. v Chubb Group of Ins. Cos., 90 NY2d 195, 199 [1997]). In such cases, an insurer who fails to issue a timely disclaimer is not prohibited from later raising the defense because “the insurance policy does not contemplate coverage in the first instance, and requiring payment of a claim upon failure to timely disclaim would create coverage where it never existed” (Matter of Worcester Ins. Co. v Bettenhauser, 95 NY2d 185, 188 [2000]).
As a corollary to the Presbyterian preclusion rule, Appellate Division case law consistently holds that a carrier’s failure to seek verification or object to the adequacy of claim forms pursuant to 11 NYCRR 65-3.5 precludes it from interposing any defenses based on such deficiencies (see e.g. Westchester Med. Ctr. v Safeco Ins. Co. of Am., 40 AD3d 984 [2d Dept 2007]; LMK Psychological Servs., P.C. v Liberty Mut. Ins. Co., 30 AD3d 727, 728-729 [3d Dept 2006]). We concur and note that an insurer that requests additional verification after the 10- or 15-business-day periods but before the 30-day claim denial window has expired is entitled to verification. In these instances, the 30-day time frame to pay or deny the claim is correspondingly reduced (see 11 NYCRR 65-3.8 [j]; Nyack Hosp. v General Motors Acceptance Corp., 8 NY3d 294, 300 [2007]).
Here, after Travelers obtained the NYS Form NF-5 and the assignment of benefits form—both of which plainly stated that the patient’s signature was “on file”—it did not ask for further verification or request the original assignment, as permitted by the regulations. Travelers also failed to pay or deny the claim within 30 calendar days of receipt of the hospital’s proof of claim. Nevertheless, Travelers argues that its neglect in demanding verification or timely denying coverage is irrelevant because the hospital’s failure to proffer a validly executed assignment equates to a lack of coverage, a defense that is not subject to preclusion under Chubb. We disagree.
*319In Chubb, the insurer asserted as a defense that the claimant’s injuries arose out of a prior work-related accident rather than a car accident. Alternatively, the carrier refused payment on the ground that the patient’s treatment was excessive. We held that the insurer was not barred from arguing that the injuries were unrelated to the accident because, if true, the treatment would not have been covered by the automobile liability policy in the first instance. On the other hand, we indicated that an excessive treatment defense ordinarily does not implicate a coverage issue, in which situation the preclusion rule applies (90 NY2d at 199).4
Here, there is no dispute that the hospital rendered medical services to Browne in the amount of $24,344.96 for injuries arising out of a motor vehicle accident, that Browne’s policy with Travelers was in effect at the time of the accident and that the policy covered the accident. In our view, any defect or deficiency in the assignment between Browne and the hospital simply does not implicate a lack of coverage warranting exemption from the preclusion rule. We therefore determine that the failure by Travelers to seek verification of the assignment in a timely manner prevents the carrier from litigating the issue now.5
To conclude otherwise, as proposed by the dissent, frustrates a core objective of the no-fault regime—“to provide a tightly timed process of claim, disputation and payment” (Presbyterian, 90 NY2d at 281). Upon receipt of a no-fault claim, the regulations shift the burden to the carrier to obtain further verification or deny or pay the claim. When, as here, an insurer does *320neither, but instead waits to be sued for nonpayment, the carrier should bear the consequences of its nonaction. To allow an insurance company to later challenge a hospital’s standing as an assignee merely encourages the carrier to ignore the prescribed statutory scheme. As we observed in Presbyterian:
“No-fault reform was enacted to provide prompt uncontested, first-party insurance benefits. That is part of the price paid to eliminate the common-law contested lawsuits . . . The tradeoff of the no-fault reform still allows carriers to contest ill-founded, illegitimate and fraudulent claims, but within a strict, short-leashed contestable period and process designed to avoid prejudice and red-tape dilatory practices” (id. at 285 [citation omitted]).
Finally, Travelers contends that an assignment of benefits is a necessary component of the hospital’s prima facie case for recovery of no-fault benefits. Even assuming that this is true, we conclude that an assignment form stating that the patient’s signature is “on file” satisfies that burden where the carrier does not timely take action to verify the existence of a valid assignment (see Hospital for Joint Diseases v Allstate Ins. Co., 21 AD3d 348 [2d Dept 2005]). Since Travelers does not otherwise contest the hospital’s entitlement to no-fault payments, the courts below appropriately awarded summary judgment to the hospital. We have considered Travelers’ remaining contentions and find them without merit.
Accordingly, the order of the Appellate Division should be affirmed, with costs.
. Originally, plaintiff Hospital for Joint Diseases, as the assignee of two other patients, jointly sued Travelers and Farmington for nonpayment of no-fault benefits. Those claims were subsequently withdrawn.
. A hospital may request payment from the insurer by submitting a properly executed authorization to pay benefits or properly executed assignment on one of the prescribed verification forms or an assignment of benefits form (see 11 NYCRR 65-3.11 [b]).
. Where a claimant submits an application for no-fault benefits (NYS Form NF-2) without verification forms, the insurer has 10 business days to forward the “prescribed verification forms it will require prior to payment of the initial claim” (11 NYCRR 65-3.5 [a]).
. As another example, courts have held that an insurance company is not prevented from later denying a claim where the injured party deliberately caused the collision as part of a fraudulent scheme, holding that an intentional crash is not an “accident” covered by the policy (see Matter of Allstate Ins. Co. v Massre, 14 AD3d 610 [2d Dept 2005]; State Farm Mut. Auto. Ins. Co. v Laguerre, 305 AD2d 490 [2d Dept 2003]).
. We note that this conclusion is consistent with Appellate Division precedents that have considered similar circumstances (see Westchester Med. Ctr. v Safeco Ins. Co. of Am., 40 AD3d 984 [2d Dept 2007]; LMK Psychological Servs., P.C. v Liberty Mut. Ins. Co., 30 AD3d 727 [3d Dept 2006]; Nyack Hosp. v Encompass Ins. Co., 23 AD3d 535 [2d Dept 2005], appeal dismissed 8 NY3d 895 [2007]; Hospital for Joint Diseases v Allstate Ins. Co., 21 AD3d 348 [2d Dept 2005]; Nyack Hosp. v Metropolitan Prop. & Cas. Ins. Co., 16 AD3d 564 [2d Dept 2005], lv denied 5 NY3d 713 [2005]; New York Hosp. Med. Ctr. of Queens v New York Cent. Mut. Fire Ins. Co., 8 AD3d 640 [2d Dept 2004], lu denied 3 NY3d 609 [2004]; Presbyterian Hosp. in City of N.Y. v Aetna Cas. & Sur. Co., 233 AD2d 433 [2d Dept 1996], lu dismissed 89 NY2d 1030 [1997]).
