New York’s no-fault system does not eliminate every car accident lawsuit. But in a covered motor-vehicle injury case, a person seeking non-economic damages such as pain and suffering generally must prove a “serious injury” under New York Insurance Law § 5102(d). The definition changed in 2026, so older articles that still rely on the former 90/180-day category may now be outdated for actions commenced on or after May 26, 2026.
Key Takeaways
- The serious-injury threshold primarily controls whether a covered claimant may pursue non-economic damages such as pain and suffering.
- A fracture remains an express serious-injury category under the current statute.
- The former 90/180-day non-permanent impairment category was removed by New York’s 2026 motor-vehicle reforms for actions commenced on or after May 26, 2026.
- Medical treatment alone is not enough; the claim still requires proof connecting the qualifying injury and limitations to the crash.
- Current New York law also requires fault to be determined before the trier of fact decides serious injury in an Article 51 non-economic-loss action.

What the Serious-Injury Threshold Actually Controls
New York is a no-fault state for many motor-vehicle injury claims. Basic no-fault benefits address certain medical expenses, lost earnings, and other covered economic losses without first requiring proof that another driver was negligent. For a fuller explanation, see Is New York a No-Fault State for Car Accidents?.
The serious-injury threshold is different. Under Insurance Law § 5104, a covered person generally may not recover non-economic loss from another covered person unless the injury satisfies the statutory serious-injury definition. Non-economic loss includes pain and suffering and similar non-monetary harm. The threshold therefore matters most when the claim seeks compensation beyond the basic no-fault system for the human impact of the injury.
The threshold is not a shortcut for deciding the entire case. A claimant may still need to prove fault, causation, the nature and duration of the injury, and the amount of legally recoverable damages. Insurance coverage and economic losses also require separate analysis.
Which Injuries Currently Qualify as “Serious Injury”?
As of September 2026, New York Insurance Law § 5102(d) lists the following categories: death; dismemberment; significant disfigurement; a 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; and significant limitation of use of a body function or system.
The current statutory text is available through New York State Open Legislation.
Some categories are straightforward to identify, such as a documented fracture. Others require a more fact-intensive medical showing. A “significant limitation,” for example, cannot be established simply by describing pain. The medical evidence, objective findings, functional restrictions, duration, treatment history, and causal relationship to the collision can all become important.
What Changed in New York in 2026?
The 2026 motor-vehicle reforms made a major change that many older online guides do not reflect. According to the New York State Department of Financial Services, Part EE of Chapter 58 removed the former 90/180-day category from the definition of serious injury. The amendment took effect May 26, 2026 and applies to actions and proceedings commenced on or after that date.
Before the amendment, the statute included a category for a medically determined non-permanent injury or impairment that prevented an injured person from performing substantially all of the material acts of usual daily activities for at least 90 of the first 180 days after the injury. That category is no longer part of the current § 5102(d) definition for actions governed by the 2026 amendment.
The same reform also amended Insurance Law § 5104 so that, in an Article 51 action for non-economic loss, the trier of fact determines fault before deciding whether the claimant sustained a serious injury.
Questions About New York’s Serious-Injury Threshold?
The 2026 changes make it especially important to evaluate the current law rather than rely on an older article or assumption about the 90/180-day rule. Marks Law Group can review the crash, medical proof, fault issues, insurance, and whether the present serious-injury categories may apply.
How Medical Proof Is Used to Establish a Qualifying Injury
A serious-injury claim should be built around medical evidence that explains the diagnosis, objective findings, functional limitations, course of treatment, prognosis, and relationship between the crash and the claimed condition. Depending on the injury, relevant material may include imaging, operative reports, range-of-motion testing, neurological findings, specialist evaluations, therapy records, and opinions concerning permanence or significant limitation.
Consistency also matters. Large unexplained gaps in treatment, records that attribute the condition to another event, or medical histories showing the same limitations before the crash can become important issues. None of those facts automatically defeats a claim, but they should be identified and addressed rather than ignored.
Does Surgery or a Fracture Automatically Prove the Claim?
A fracture is expressly included in the statute, so a crash-caused fracture satisfies a listed serious-injury category. That does not mean every other issue disappears. The claimant still must prove causation, fault where disputed, and the losses caused by the injury.
Surgery is different. Surgery can be strong evidence that an injury is substantial, but “surgery” itself is not a separate statutory category. The underlying condition and resulting limitations must still fit a category recognized by § 5102(d).
What if You Had a Prior Injury or Degenerative Condition?
A pre-existing condition does not automatically prevent a claim, but causation becomes more important. The issue may be whether the collision caused a new injury, aggravated an existing condition, or produced new limitations beyond what existed before the crash. Prior imaging, earlier treatment records, post-crash diagnostic findings, and the medical history can all matter.
This is one reason serious car accident cases should be evaluated from the records rather than from a diagnosis label alone. The same diagnosis can have very different legal significance depending on the person’s pre-crash condition, objective findings, treatment, and functional impact.
What if the Insurance Company Says Your Injury Is Not “Serious”?
An insurer’s position is not the final legal determination. A serious-injury dispute should be evaluated against the current statutory categories and the available medical proof. A car accident lawyer can review the records, identify evidentiary gaps, and evaluate whether the claim has the proof required to proceed.
