If you’ve been injured in a car accident in New York City or the surrounding areas, you may have heard that you need a “serious injury” to file a lawsuit. This requirement, known as the serious injury threshold, is one of the most important legal concepts in New York personal injury law. It is also referred to as the “Threshold Rule.” Understanding whether your injury meets “the threshold” can determine your entire path to compensation.
Update: In May 2026, Governor Kathy Hochul signed tort reform legislation that eliminated one category of serious injury and introduced new fault rules for motor vehicle cases. This article reflects those changes.
This article explains New York’s serious injury threshold under Article 51 of the state’s Insurance Law, the eight categories that qualify, how insurance companies try to deny claims based on threshold defenses, and what evidence you need to prove your case.
What You’ll Learn:
- The eight specific categories of serious injury under New York law following the 2026 tort reform
- Why the threshold matters for your ability to recover compensation
- Common defenses insurance companies use to claim you don’t meet the threshold
- The medical evidence required to prove a serious injury and pursue a lawsuit
- How New York’s No-Fault system creates the serious injury threshold requirement
- How the 2026 tort reform eliminated one category, introduced modified comparative negligence, a new trial sequencing rule, a recovery cap for certain plaintiffs, and changed the rules for motor vehicle accident victims
The Eight Categories of Serious Injury
Important Update: Effective May 27, 2026, Governor Hochul’s tort reform eliminated one of the previous nine categories (the 90/180-day rule), reducing the qualifying categories from nine to eight. See below for a full explanation of this change.
New York Insurance Law Section 5102(d) defines “serious injury” threshold through eight specific categories. If your injury falls into any one of these categories, you meet the threshold and can pursue a lawsuit for all your injuries. Remember, this rule only applies to car accidents.
The Eight Categories
| Category | Description | Key Considerations |
| Death | Fatal injuries resulting from the accident | Applies to wrongful death claims |
| Dismemberment | Loss of a limb or body part | Must be actual loss, not just loss of function |
| Significant Disfigurement | Visible scarring or alteration of appearance | Subjective standard¸Å often requires jury determination |
| Fracture | Any broken bone | Includes teeth; does not need to be compound or comminuted |
| Loss of Fetus | Pregnancy loss caused by the accident | Must be medically documented and causally related |
| Permanent Loss of Use | Total and complete inability to use a body part | Requires 100% loss of function permanently |
| Permanent Consequential Limitation | Permanent injury causing more than minor limitation | Requires objective medical evidence of permanency |
| Significant Limitation | Non-permanent injury causing more than minor limitation | Must be significant, not just inconvenient |
Update: A ninth category (the 90/180-day rule) was eliminated by Governor Hochul’s 2026 tort reform. Claimants can no longer satisfy the threshold by showing a non-permanent injury prevented them from performing substantially all of their usual and customary daily activities for at least 90 of the 180 days immediately following the accident.
Most Commonly Litigated Categories
The “limitation” categories (permanent consequential limitation, significant limitation, and 90/180) are the most heavily disputed because they involve subjective assessments of how much an injury has impacted your life.
Update: With the 90/180-day category now eliminated, victims of soft tissue injuries and other non-permanent impairments face a higher bar to qualify.
The legal standard: Your injury must result in “more than a minor limitation” of function. This vague standard requires strong medical evidence to prove.
Why the Serious Injury Threshold Matters
The threshold requirement has profound implications for motor vehicle accident victims in New York:
Impact on Your Case
| If You Don’t Meet the Threshold: | If You Meet the Threshold: |
|
|
Update: The 2026 tort reform introduced several new rules for motor vehicle cases. First, New York moved to a modified comparative negligence standard: if a jury finds you more than 50% at fault, you are completely barred from recovery, even if your injuries meet the threshold. Under prior law, partial fault only reduced your recovery.
Second, juries must now determine fault before evaluating the serious injury threshold, meaning if the plaintiff is found more than 50% at fault, the trial stops, and no damages are awarded. Third, non-economic damages (pain and suffering) are capped at $100,000 for plaintiffs who were operating an uninsured vehicle, driving while impaired with a conviction, or committing a felony at the time of the accident, unless the accident resulted in death.
Real-World Example
Consider two accident victims with neck injuries:
| Victim A has documented and provable range-of-motion limitations of 25% compared to normal function, confirmed by objective medical testing. Their doctor states the limitation is permanent and significantly affects daily activities. | Victim B experiences neck pain and discomfort but has only a 10% reduction in range of motion, with medical records showing they returned to work within two weeks. |
Victim A likely probably meets the serious injury threshold under the “permanent consequential limitation” category. Victim B likely does not. The difference determines whether they can pursue a lawsuit for compensation beyond No-Fault benefits.
Common Insurance Company Defenses
Insurance companies aggressively challenge whether injuries meet the serious injury threshold. Understanding their tactics helps you prepare a stronger case.
Threshold Defense Strategies
| Defense Tactic | How It Works | How to Counter It |
| Gaps in Treatment | Arguing you didn’t seek consistent medical care, suggesting injuries weren’t serious | Maintain regular treatment and document reasons for any gaps |
| Pre-Existing Conditions | Claiming your injuries existed before the accident | Prove the accident aggravated or worsened pre-existing conditions |
| Independent Medical Exams (IMEs) | Sending you to their doctor, who often minimizes injuries | Ensure your own doctors provide detailed, objective reports |
| Lack of Objective Evidence | Arguing that your claims are based only on subjective complaints | Obtain MRIs, X-rays, range of motion tests, and other objective data |
| Quick Return to Activities | Showing you returned to work or daily activities quickly | Document ongoing limitations and modifications to activities |
| Minor Accident, Minor Injuries | Suggesting low-impact crashes can’t cause serious harm | Medical evidence proves injury severity, not vehicle damage |
| Fault Attribution | Arguing under the 2026 law that you were more than 50% at fault, which bars recovery entirely. | Preserve all evidence immediately and contact an attorney early to protect your fault position. |
Evidence Required to Prove a Serious Injury
Successfully proving you meet the serious injury threshold requires comprehensive medical documentation. The law requires objective medical evidence, not just your testimony about pain or limitations. Legally, as the person suing, the burden is on you to prove these serious injuries. These create several hurdles for a successful lawsuit.

The 90/180-Day Category Has Been Eliminated
As of May 27, 2026, the 90/180-day category no longer exists under New York Insurance Law. If your injuries do not fall within one of the eight remaining categories, you cannot pursue a pain-and-suffering lawsuit, regardless of how significantly your daily life was disrupted during recovery.
The “Range of Motion” Challenge
For limitation categories, insurance companies focus heavily on range-of-motion measurements. Some studies have shown that reductions below 20% are often deemed insufficient to meet the threshold, while reductions of 25% or more typically qualify.
Insurance companies will argue:
- Your range-of-motion tests weren’t conducted with proper instruments.
- The reductions aren’t significant enough to constitute “more than minor” limitation.
- Your doctor’s findings are subjective and unreliable.
Understanding New York’s No-Fault Insurance System
New York operates under a No-Fault insurance system designed to reduce the number of minor motor vehicle accident cases clogging court dockets. Under this system, your own insurance company pays for your medical expenses and lost wages up to $50,000, regardless of who caused the accident.
While this provides quick access to basic compensation, there’s a trade-off. Filing a lawsuit against the at-fault driver for pain and suffering is only viable if your injuries meet specific legal criteria defined as a “serious injury.”
Technically, nothing prevents you from filing, but without meeting this threshold, the case will almost certainly be dismissed before trial, typically at the summary judgment stage. In practice, the serious injury threshold functions as a legal barrier to recovery, not just to filing.
This legal barrier is codified in Section 5104(a) of New York’s Insurance Law and is commonly referred to as the serious injury threshold.
How the Threshold Works
The threshold creates two separate categories of damages in motor vehicle cases:
| Damage Type | Threshold Requirement | What It Means |
| Economic Damages | Must exceed Basic Economic Loss ($50,000) | Medical bills, lost wages, out-of-pocket expenses |
| Non-Economic Damages | Must have a “Serious Injury” and be 50% or less at fault (under the 2026 law). | Pain and suffering, loss of enjoyment of life, and emotional distress |
Important note: These two categories are analyzed independently. You can recover economic damages above $50,000 without proving serious injury, and you can pursue pain and suffering damages if you meet the serious injury threshold and are not found to be more than 50% at fault, even if your bills are under $50,000.
Take Action to Protect Your Rights
Understanding New York’s serious injury threshold is essential, but navigating the legal complexities and building a strong case requires experienced representation. With the 2026 tort reform now in effect, the path to recovery is narrower, making early documentation and experienced legal representation more critical than ever.
