The serious injury threshold is the gate between a $50,000 PIP claim and a full personal injury lawsuit that can recover hundreds of thousands of dollars or more. It is the first thing the insurance carrier evaluates when assessing damages. It is the basis of the most commonly filed defense motion in New York car accident litigation. And it is the single most important reason why the quality of your medical documentation — starting at the first visit — determines whether your case lives or dies.
Every serious car accident case in New York runs through the threshold. A plaintiff who cannot establish a qualifying injury under Section 5102(d) is limited to the $50,000 in no-fault benefits, regardless of how clear the liability is and regardless of how traumatic the accident was. A plaintiff who can establish a qualifying injury has access to the full range of compensatory damages: past and future medical expenses, full lost wages, pain and suffering, and loss of enjoyment of life. The difference between these two outcomes is determined by the medical record. Understanding how the threshold works — and what evidence it requires — is the foundation of every serious New York auto accident case.
Why the threshold exists
New York’s no-fault system was enacted in 1973 to address concerns about litigation volume and insurance costs. The legislature’s compromise: injured people would receive prompt no-fault benefits regardless of fault, in exchange for a restriction on their ability to sue for pain and suffering. That restriction is the serious injury threshold. Minor injuries are compensated through no-fault. Serious injuries can still be pursued through a personal injury lawsuit. The threshold is the line that separates the two.
This structure has important practical consequences. Every minor fender-bender in New York is resolved through no-fault benefits, not through litigation. This keeps the court system from being overwhelmed by minor claims. But it also means that people with injuries that seem serious to them but do not meet the legal threshold are left with only the no-fault benefits — they have no access to pain and suffering damages, no recovery for future medical expenses beyond the $50,000 cap, and no compensation for the full impact of the injury on their lives. The threshold is not a hurdle to be jumped casually. It is a barrier that, when not met, ends the case.
The five statutory categories
Insurance Law Section 5102(d) defines serious injury through five categories. These are the statutory terms and they must be stated accurately: significant limitation of use of a body function or system; permanent consequential limitation of use of a body organ or member; significant disfigurement; fracture; or a medically determined injury or impairment of a non-permanent nature which prevents the injured person from performing substantially all of the material acts which constitute their usual and customary daily activities for not less than ninety days during the one hundred eighty days immediately following the occurrence. Your case must establish at least one of these categories with medical evidence. If it does not, the case is dismissed.
Fracture: the clearest path
A fracture meets the threshold automatically. An X-ray, CT scan, or MRI confirming the fracture, combined with the treating physician’s documentation, satisfies the requirement without further analysis. A broken bone is a fracture regardless of severity — a hairline fracture of the wrist qualifies the same as a compound fracture of the femur. Dental fractures qualify. Rib fractures qualify. The category is one of the few in Section 5102(d) that does not require a showing of significance, limitation, or duration. The fracture itself is sufficient.
This is one reason imaging matters in New York car accident cases. A patient who has neck pain but whose X-ray shows a small compression fracture of a cervical vertebra has established the threshold through that finding alone. Without the imaging, the same patient would have to rely on the significant limitation or 90/180 day categories, both of which require more extensive evidence. The complexity arises in the non-fracture categories, where the medical evidence must demonstrate a measurable, objective limitation that meets the statutory standard.
Significant limitation of use of a body function or system
This category requires objective medical evidence of a measurable limitation in the function of a body part or system. Range of motion deficits documented in degrees using a goniometer are the most common form of evidence — a reduction from normal range of motion that is documented at multiple visits and correlated with imaging findings supports this category. Neurological findings such as diminished reflexes, radiculopathy confirmed by EMG, positive straight leg raise tests, or sensory deficits also support it. Imaging showing structural injury — a disc herniation, a labral tear, a ligament rupture — provides objective support.
Subjective complaints alone — “patient reports pain” without corresponding objective findings — are not sufficient. The defense will file a threshold motion arguing the medical evidence does not support a significant limitation, supported by the IME physician’s report concluding the plaintiff’s self-reported symptoms are not corroborated by clinical findings. If the treating physician’s records contain only subjective notes, the motion will be granted and the case dismissed.
The limitation must be significant — the courts have interpreted this to mean more than minor, mild, or slight. A limitation of a few degrees in cervical range of motion, particularly if it resolves with treatment, is often not considered significant for threshold purposes. A limitation of 25% or more in range of motion, documented persistently over time with objective correlating findings, typically supports the category. The specific numeric threshold is not defined in the statute, but the pattern in New York case law shows that significance requires both the magnitude of the limitation and its persistence.
Permanent consequential limitation
This category requires proof that the limitation is permanent and that it has a consequential effect. The treating physician must opine, based on clinical findings and the course of treatment, that the limitation is expected to be permanent. Imaging showing a structural injury that will not resolve — a disc herniation that did not respond to conservative treatment, a labral tear, a ligament injury with residual instability — supports permanency. The physician’s opinion must be supported by the objective findings, not based solely on the patient’s reported symptoms.
The defense’s IME physician will examine the claimant and provide a competing opinion. The IME physician typically concludes that any limitation is not permanent, that the plaintiff has reached maximum medical improvement, and that continued symptoms are unrelated to the accident. The strength of the treating physician’s documentation determines which opinion prevails. A treating physician’s affirmation detailing the objective findings, the imaging correlations, and the reasoning behind the permanency opinion can defeat the IME. A treating physician’s conclusory statement that “the patient has a permanent injury” without supporting analysis typically cannot.
Significant disfigurement
This category applies when the accident has caused visible scarring or other disfigurement that a reasonable person would find unattractive, objectionable, or the subject of pity or scorn. Scars on the face, neck, or exposed portions of the body frequently meet this category. The standard is objective — whether a reasonable person would consider the disfigurement significant — not subjective to the plaintiff’s own feelings. Photographs of the disfigurement at various stages of healing are essential evidence. Before-and-after photographs comparing the plaintiff’s appearance before the accident and after establish the effect of the injury on appearance.
The 90/180 day category
This is the most frequently litigated threshold category because it requires specific proof of what the injured person could not do during a defined time period. The standard requires that the injury prevented you from performing substantially all of the material acts which constitute your usual and customary daily activities for at least 90 of the first 180 days after the accident. “Substantially all” means nearly everything you normally do, not just some activities. Medical records documenting disability from work, inability to perform household tasks, inability to care for children, and inability to engage in recreational activities during the relevant period are the evidence. Employment records confirming absence from work during the 180-day window support the claim. A contemporaneous symptom journal documenting daily limitations provides the granular detail that medical notes may omit.
The defense attacks this category by pointing to any activity during the 180-day period that suggests the claimant was functioning. A return to work at light duty, a social media post showing an outing, a surveillance video of the claimant walking without apparent difficulty, medical records noting improvement — any of these can be used to argue that the claimant was not prevented from performing “substantially all” daily activities. The 90/180 day category requires careful documentation from the first day and consistent limitations throughout the period.
The 90 days do not need to be consecutive. They need to total 90 days within the first 180. A plaintiff who was fully disabled for 60 days, returned to light duty for 45 days, and then had a setback that required another 30 days off can still meet the 90-day requirement, provided the days of substantial disability are documented. But the documentation needs to be thorough — medical records, employment records, witness testimony from family members about the plaintiff’s inability to perform specific activities. Vague testimony that “I was pretty much out of it for a few months” is not enough.
How the carrier attacks the threshold
The defense attorney files a motion for summary judgment arguing that the medical evidence does not establish a serious injury under any category. The motion is supported by the IME physician’s report concluding that the injuries are not significant, that any documented deficits are attributable to pre-existing degeneration rather than the accident, and that the claimant’s reported symptoms are inconsistent with the clinical findings. The IME physician often points to pre-existing degenerative changes on imaging — disc bulges and arthritis are nearly universal in adults — and argues that the plaintiff’s current complaints are the result of pre-existing conditions unrelated to the accident.
Your attorney responds with the treating physician’s affirmation detailing the objective findings, the imaging results, the causation opinion connecting the injury to the accident, and the permanency assessment. The treating physician’s affirmation must be supported by clinical records showing the objective findings at multiple visits — a single normal examination followed by years of complaints is not sufficient. The physician must explain why the current symptoms are caused by the accident rather than by pre-existing conditions. The physician must address the specific criticisms the IME raised, point by point.
If the treating physician’s documentation is thorough — objective measurements at every visit, imaging correlations, a clear causation opinion — the motion is denied and the case proceeds to trial. If the documentation is thin, the case is dismissed. Threshold motions are not a formality. They are the battleground on which many New York auto accident cases are won or lost.
The treating physician’s documentation is the foundation
The threshold is not met by the injured person’s testimony about how much pain they experience. It is met by the treating physician’s clinical findings documented in the medical record. Range of motion measured in degrees with a goniometer. Neurological findings recorded at each visit. Imaging interpreted by the treating physician and correlated with the clinical presentation. Functional limitations documented with specificity. Every visit produces a record. Every record either supports or undermines the threshold.
The medical evidence does not build itself. It requires a treating physician who documents thoroughly and an attorney who monitors the documentation throughout the case. A treating physician who uses brief EMR templates and records only “patient reports ongoing pain” at every visit has not generated the evidence the threshold requires. An attorney who reviews the records periodically and identifies gaps can raise the issue with the physician — the physician decides what to find, but the physician should know that thorough documentation of objective findings is important for the legal case as well as for medical treatment.
How Schwartzapfel Holbrook builds threshold evidence
At Schwartzapfel Holbrook, we evaluate the serious injury threshold in every car accident case from the first consultation. We review the medical records for objective findings, identify which threshold categories the evidence supports, and coordinate the timing of imaging, specialist referrals, and functional assessments so that the evidence develops in the way the legal standard requires. We do not wait for the defense to file a threshold motion to discover whether the evidence is sufficient. We build the evidence from the beginning so the threshold is established before it is ever challenged. In cases where the evidence does not support a strong threshold position, we discuss that honestly with the client and evaluate whether the case should be pursued, settled early, or declined. The threshold is not optional — it is the foundation of every serious New York auto accident case, and it is the foundation we build first.
