The New York Serious Injury Threshold and Its Eight Categories

The eight serious injury categories in New York Insurance Law 5102(d)

Eight categories. Your injury only has to fit one of them, and the category you plan to prove decides which medical proof your case needs.

Death

Statutory words: an injury that results in death. The category is automatic once the crash is shown to have caused the death. The claim itself changes shape: the estate brings a wrongful death action under New York EPTL section 5-4.1 within two years of the death, and a separate survival claim covers the pain the person felt before dying. What insurers argue: causation, usually that an unrelated medical event and not the crash ended the life. Medical examiner findings and the hospital record answer that.

Dismemberment

Statutory words: dismemberment. The loss of a body part, most often a finger, hand, foot or limb, whether it was severed in the crash or amputated by surgeons afterward. Proof is the operative report and the photographs. Nothing about severity has to be argued. What insurers argue: almost nothing on the category itself, so the fight moves to fault and to the value of the loss, including prosthetics, home modification and the work the person can no longer do.

Significant disfigurement

Statutory words: significant disfigurement. New York courts ask whether a reasonable person viewing the injured person would find the condition unattractive, objectionable or the subject of pity. Facial scarring, keloids, skin grafts, burn scars and surgical scars all qualify when they are visible and permanent. Proof is dated photographs over time plus a treating doctor or plastic surgeon on permanence. What insurers argue: that the scar is fading, is small, or sits where clothing hides it.

Fracture

Statutory words: a fracture. Any broken bone, of any size, anywhere. A fracture needs no degree of permanence and no loss of function. A hairline fracture of a rib, a chip fracture of an ankle and a nasal fracture all satisfy the category on the imaging alone. Proof is the X ray, CT or MRI plus a radiologist reading it. What insurers argue: that the finding is a congenital variant, an old healed injury or a reading error, which is why the imaging should be read by a physician for your side too. Because the category is met by the break alone, fracture cases move fastest: the fight goes straight to fault and value rather than to whether you are allowed to sue at all.

Loss of a fetus

Statutory words: loss of a fetus. A pregnancy lost because of the crash meets the threshold on its own terms, at any stage. Proof is the obstetric record before and after the collision and a physician who connects the loss to the trauma. What insurers argue: that the loss had another cause. Because the medical record is short and specific, this category is usually decided on the obstetric chart rather than on an examination months later.

Permanent loss of use of a body organ, member, function or system

Statutory words: permanent loss of use of a body organ, member, function or system. New York courts read this category strictly: the loss of use must be total, not partial. A paralyzed limb, a blind eye, a removed organ and a joint fused so it no longer moves are the typical examples. A painful, partly limited shoulder is not this category, and claims are often argued here when they belong in one of the limitation categories below. Proof is objective testing plus a physician on permanence. What insurers argue: that some residual function remains, which defeats the category.

Permanent consequential limitation of use of a body organ or member

Statutory words: permanent consequential limitation of use of a body organ or member. This is the category most disc, knee and shoulder cases rely on. It needs three things: a structural injury visible on imaging, a limitation that is consequential rather than minor, and a physician's opinion that the limitation is permanent. The proof that works is a measured loss of range of motion compared against normal values, repeated at intervals, and a final examination close to the motion. What insurers argue: degeneration rather than trauma, a gap in treatment, or a normal examination by their doctor. The difference between this category and the one below it is time: here a physician has to be willing to say the limitation will not resolve, which normally means waiting until treatment has plateaued before that report is written.

Significant limitation of use of a body function or system

Statutory words: significant limitation of use of a body function or system. The same evidence as the category above, without the requirement that the limitation last forever. It must still be significant, meaning more than minor, mild or slight, and it must be shown by objective findings rather than by how much pain you report. A documented radiculopathy with a matching MRI, or a shoulder that measures well short of normal for months, fits here. What insurers argue: that the limitation is minor, that it resolved, or that a subjective complaint is all that is really in the chart. Duration helps. A limitation measured across several months reads as significant. The same finding recorded once, in week two, usually does not.

How the New York limitation categories are proved

With numbers, not adjectives. The two limitation categories carry most New York cases, and both are decided on objective medical evidence a judge can read.

The record that survives a threshold motion usually has four parts. First, imaging that shows something structural: a herniation or bulge that touches a nerve root, a labral or meniscal tear, an annular tear, a rotator cuff tear. Second, range of motion measured with a goniometer or inclinometer and compared to stated normal values, taken more than once, including a recent examination rather than only one from the week of the crash. Third, continuous treatment. Physical therapy that stops in month three and resumes in month fourteen invites the argument that you were fine in between, and if insurance ran out, the record has to say so in writing. Fourth, a physician's narrative that ties the findings to the collision and addresses your prior conditions head on.

That last part decides more cases than anything else. Almost every adult spine shows degenerative change on an MRI, so a report that says only "disc herniation at L5 to S1" hands the defense its argument. A report that says the change was present but asymptomatic, and that the crash converted it into a symptomatic, measurable limitation, is the version that holds. The same logic applies to knees and shoulders. If you had an earlier injury to the same body part, get the old records to your lawyer early instead of hoping nobody finds them.

What does not work: pain diaries alone, a single normal looking examination, a chiropractic note that records tenderness without measurement, or an MRI with no clinician connecting it to your symptoms. New York courts have consistently held that a subjective complaint of pain, standing alone, satisfies neither limitation category.

It helps to know how the motion runs. The defense files first and carries the opening burden, usually with an examination report and a radiologist who reviews your films. If that showing is made, the burden shifts to you, and your answer has to be sworn medical evidence rather than argument from a lawyer. A treating physician's affirmation, with measurements, dates and an opinion on causation and permanence, is the document that defeats the motion. An unsworn letter, a report from a provider who never examined you, or a narrative that ignores your prior records will not do it. If the motion succeeds, the pain and suffering claim is dismissed before a jury ever hears the case, so the affirmation is prepared in advance rather than in the two weeks after the motion lands.

If your New York lawsuit was filed before May 26, 2026

The change turns on when the lawsuit is filed, not on the crash date. If your lawsuit was already filed before May 26, 2026, the 90 out of 180 day route is still available to you.

That category covered a medically determined injury or impairment of a non permanent nature that prevented you from performing substantially all of your usual and customary daily activities for at least 90 of the first 180 days after the crash. It was the category for people who were genuinely disabled for months and then recovered, and it did not require permanence.

Proving it takes a different record. You need a doctor who actually wrote down the restriction at the time, week by week, rather than a letter composed a year later. You need the 90 days to fall inside the first 180, counted from the crash date. And you need the restriction to reach substantially all of your usual activities, not just work: a person who returned to full duty in week six generally cannot satisfy the category even if the job was miserable. Out of work notes, school records, an employer's attendance file and a household member describing what you could not do at home all carry weight here.

Injuries that usually meet the New York threshold

No injury is automatic except the named ones. This table shows which category each common crash injury normally travels under, and what actually decides it.

How insurers attack the New York serious injury threshold

The same four arguments appear in nearly every file. Knowing them in month one is how you keep them out of the motion in year two.

• Pre existing condition. Your MRI shows degeneration, so the insurer says the crash changed nothing. The answer is a physician who reviews the old records and explains what was asymptomatic before and what is measurable now.
• Treatment gap. Any break in care becomes a claim that you had recovered. If a gap happens because no fault benefits were cut off, because of a pregnancy, a job or childcare, the reason belongs in the chart in writing when it happens.
• The examining doctor. The carrier sends you to its own orthopedist, who records full range of motion and a resolved injury. That report is an opinion, not a verdict, and a treating physician's measured findings rebut it. Take the exam seriously, bring your imaging, and describe your real limits without exaggerating them.
• Subjective complaints only. If the chart records pain and nothing measured, there is nothing for a judge to weigh. Ask for range of motion measurements at each visit and make sure they are written down.

Surveillance and social media feed all four arguments. A photograph of you at a wedding, a gym check in or a hiking post gets attached to the motion without the context of what the rest of that week cost you. Assume the defense will find it.

There is also a timing tactic worth naming. Carriers often cut off no fault benefits after an examination concludes that treatment is no longer necessary, knowing most people stop going when the bills stop being paid. The cutoff and the treatment gap then arrive as a matched pair in the summary judgment motion. Challenging the cutoff quickly, in no fault arbitration, is part of protecting the threshold claim rather than a separate errand.

What the New York threshold does not affect

The threshold controls one thing only: pain and suffering from the at fault driver. These parts of your case run whether you meet it or not.

Your no fault benefits are paid regardless of fault and regardless of the threshold, and under New York Insurance Law section 5106 they are overdue if the carrier does not pay within 30 days of proof of claim. Your claim for economic losses above the 50,000 dollar limit, such as surgery bills and long term wage loss, does not require a serious injury. Your property damage claim does not either. And every deadline keeps running while the threshold question is open.

What happens if you do not meet the New York threshold

You do not walk away with nothing. What you lose is the pain and suffering claim, not the rest of the case.

No fault still pays your medical treatment and part of your wages up to the basic economic loss limit. Economic losses above that limit remain recoverable from the at fault driver, because New York Insurance Law section 5104 restricts non economic loss, not out of pocket loss. Your vehicle damage, rental and diminished value claims are unaffected. If the driver who hit you was uninsured, impaired or committing a felony, the threshold does not shield them at all, although non economic loss in that situation is limited.

The honest part: a case with no threshold category is worth far less, and a lawyer who promises otherwise is selling something. The better use of the first six months is making sure the category you do have is documented, because most cases that fail the threshold fail on missing measurements rather than on a minor injury. Our page on what a New York car accident settlement is worth explains how that plays out in value.

One more thing worth knowing: the question is not closed forever on the day an adjuster says no. An injury can qualify later. A disc that seemed manageable at month three can need surgery at month ten, and a shoulder that measured close to normal in the spring can be measurably limited by the fall. As long as the lawsuit is filed inside the three year deadline, the record keeps developing and the category is decided on the whole file, not on the first examination. That is another reason not to sign a release early in a case that is still changing.
