What Is New York’s Serious Injury Threshold (Insurance Law 5102)?

New York’s serious injury threshold is a statutory requirement, set by New York Insurance Law section 5102(d), that a motor-vehicle plaintiff must satisfy to sue for pain and suffering under the state’s no-fault system. Only an injury that falls within one of the statute’s defined categories clears the threshold and permits recovery of noneconomic damages.

This article explains what the serious injury threshold is, which statutory categories a plaintiff can rely on after New York’s 2026 amendments, how the threshold interacts with the state’s revised comparative-fault rule and how the requirement is proven in practice. For New York practitioners, the threshold is the first gate every crash case must pass.

What Is the Serious Injury Threshold Under Insurance Law 5102?

The serious injury threshold is the statutory dividing line that determines whether an injured motorist may step outside no-fault and sue the at-fault driver for noneconomic damages. Under New York’s no-fault insurance scheme, first-party benefits pay medical bills and lost earnings regardless of fault, but they do not compensate pain and suffering. To reach those damages, a plaintiff must show that the injury qualifies as “serious” within the meaning of section 5102(d). If it does not, the claim for pain and suffering is dismissed as a matter of law.

The threshold exists to filter out minor-injury litigation while preserving a remedy for genuinely serious harm. Because it is a legal standard applied to medical proof, it is frequently litigated on summary judgment, where the defense argues the injury is not serious and the plaintiff marshals objective evidence that it is.

• The threshold applies only to motor-vehicle cases governed by New York’s no-fault law.
• No-fault benefits cover economic loss; the threshold controls access to noneconomic damages.
• Whether an injury is “serious” is often decided before trial on a dispositive motion.
• A plaintiff who fails to meet the threshold cannot recover for pain and suffering.

What Are the Statutory Categories of Serious Injury in 2026?

New York’s 2026 amendments to the motor-vehicle liability law reshaped the threshold by eliminating the former “90/180-day” category, leaving eight statutory categories a plaintiff may invoke. A plaintiff need satisfy only one category to clear the threshold, and counsel routinely plead several in the alternative because a single injury can qualify under more than one heading. The categories are drawn directly from the text of section 5102(d) as amended.

The eight remaining categories of serious injury are:

• Death.
• Dismemberment.
• Significant disfigurement.
• Fracture.
• Loss of a fetus.
• Permanent loss of use of a body organ, member, function or system.
• Permanent consequential limitation of use of a body organ or member.
• Significant limitation of use of a body function or system.

The removal of the 90/180-day category — which had allowed recovery where an injury prevented a plaintiff from performing substantially all of their usual daily activities for at least 90 of the 180 days following the crash — is the most consequential change for soft-tissue and non-fracture cases. Under the amended statute, a plaintiff whose injury does not produce a fracture, permanent loss, permanent consequential limitation or significant limitation faces a materially higher bar than under prior law.

How Do the 2026 Comparative-Negligence Changes Affect Recovery?

The same 2026 reforms adopted a modified comparative-negligence bar for motor-vehicle cases, so a plaintiff found more than 50% at fault is barred from recovering noneconomic damages. This is a significant departure from New York’s traditional pure comparative negligence rule, under which a plaintiff could recover reduced damages no matter how large their own share of fault. For crash cases, the threshold question and the fault question now operate as two separate gates.

The practical effect is that a plaintiff must both clear the serious injury threshold and keep their comparative fault at 50% or below to reach pain-and-suffering damages. A plaintiff who is 51% or more responsible for the collision recovers no noneconomic damages, even with a catastrophic, threshold-qualifying injury.

• The modified bar applies to noneconomic damages in motor-vehicle cases.
• A plaintiff more than 50% at fault recovers nothing for pain and suffering.
• The rule replaces pure comparative negligence in this specific context.
• Economic loss remains governed by no-fault benefits and separate liability principles.

How Is a Serious Injury Proven Under Section 5102?

A serious injury is proven with objective, admissible medical evidence tying a qualifying condition to the crash, not merely with a plaintiff’s subjective complaints of pain. Courts expect competent proof — imaging, range-of-motion measurements and physician opinion — that identifies the injury and connects it causally to the collision. The defense typically responds with its own examining physician and argues that any limitation is minor, degenerative or unrelated to the accident.

Because the threshold is a question of law when the facts are undisputed, much of the fight occurs on summary judgment. A defendant carries the initial burden of showing the injury is not serious, after which the plaintiff must raise a triable issue with objective findings. The interplay between the threshold and no-fault also distinguishes New York’s approach from other no-fault states such as Florida, whose framework is described in Florida’s no-fault (PIP) statute.

1. Identify which of the eight statutory categories the injury fits.
2. Gather objective medical proof — imaging, quantified deficits and physician opinion.
3. Establish causation linking the qualifying injury to the motor-vehicle crash.
4. Anticipate the defense examination and preserve contemporaneous treatment records.

Conclusion

New York’s serious injury threshold under Insurance Law section 5102(d) is the statutory prerequisite that a motor-vehicle plaintiff must satisfy before recovering pain-and-suffering damages within the no-fault system. Following the 2026 amendments, eight categories remain after the elimination of the 90/180-day category, and a newly modified comparative-negligence bar denies noneconomic recovery to a plaintiff more than half at fault. For New York counsel, meeting the threshold with objective medical proof — and managing comparative fault — now defines the viability of a crash claim. Practitioners should confirm the current statutory text and controlling appellate authority when evaluating any case.
