What Does ‘Serious Injury’ Mean Under New York Law?
In New York, car accident victims are subject to the state’s no-fault insurance system, which limits the ability to file a personal injury lawsuit unless the injuries meet the serious injury threshold. This threshold is defined under New York Insurance Law § 5102(d) and determines whether an injured person can step outside the no-fault system to pursue compensation for non-economic damages like pain and suffering.
Understanding how serious injury is defined is critical for anyone injured in a car crash, especially when medical bills and lost wages go beyond basic economic loss coverage.

The No-Fault Insurance System in New York
New York is a no-fault state, meaning that your own insurance company typically pays for medical treatment, lost wages, and other basic expenses after a car accident, regardless of who was at fault. These benefits are limited to what is known as basic economic loss, generally up to $50,000.
However, if your injuries are considered serious under the law, you may be able to pursue a personal injury claim against the at-fault driver to recover additional compensation, including damages for emotional distress and long-term suffering.
Legal Definition of Serious Injury in New York
Under New York law, a serious injury includes one or more of the following conditions:
- 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
- A medically determined injury or impairment that prevents the injured person from performing substantially all of the material acts which constitute their usual daily activities for at least 90 of the 180 days immediately following the accident
These categories are interpreted on a case-by-case basis, and medical documentation is critical in proving that an injury qualifies under one or more of these definitions.
Common Injuries That May Qualify
While some injuries, such as fractures or loss of a limb, clearly meet the threshold, others require more thorough proof. Injuries like herniated discs, torn ligaments, or traumatic brain injuries may qualify if supported by objective medical evidence.
In some cases, soft tissue injuries or conditions that lead to a significant limitation of use can also meet the serious injury threshold, but only when confirmed by medical professionals through imaging studies, physical exams, and expert testimony.
The Role of Medical Evidence
Medical evidence plays a central role in demonstrating the seriousness of your injury. The courts require objective proof, such as:
- Medical records and diagnostic test results
- Reports from treating physicians or specialists
- Evidence of physical therapy and ongoing treatment
- Documentation of limitations in daily activities
- Proof of medical expenses and treatment plans
A medically determined injury must be diagnosed and supported by credible healthcare providers. Insurance companies and defense attorneys often challenge claims by arguing the injury is non-permanent or not disabling, which is why proper treatment and consistent documentation are essential.

Why the Threshold Matters
If your injury does not meet the serious injury threshold, you cannot file a lawsuit for non-economic damages. That means no compensation for pain and suffering, mental anguish, or long-term loss of enjoyment of life.
If your injury qualifies, however, you may recover compensation for:
- Future medical expenses
- Loss of earning capacity
- Emotional and psychological impacts
- Long-term disability or impairment
Because the legal interpretation of what qualifies as a serious injury can be complex, consulting an experienced personal injury attorney is one of the most important steps you can take after a car accident.
