Proving a Serious Injury Under New NY Auto Law (2026)

Proving that another driver caused a New York car accident is only one part of many automobile injury cases. To recover compensation for pain and suffering in an action governed by New York’s No-Fault law, an injured person generally must also establish a “serious injury” within the meaning of Insurance Law § 5102(d). New York changed that definition in 2026 by eliminating the longstanding 90/180-day category for actions and proceedings commenced on or after May 26, 2026.

The change places greater importance on determining whether the medical evidence establishes one of the eight serious-injury categories that remain. Those categories include fractures and certain other injuries specifically identified by the statute, as well as permanent loss of use, permanent consequential limitation of use, and significant limitation of use. For people with spinal, shoulder, knee, neurological, and other injuries that do not fall within one of the statute’s more readily identifiable categories, the quality of the medical evidence and proof of functional limitation can become central to the case.

A diagnosis alone does not necessarily answer the serious-injury question. MRIs, CT scans, EMG studies, surgical findings, measured restrictions in movement, neurological findings, treating physicians’ examinations, medical history, causation, treatment records, and other evidence may become important depending on the injury and statutory category claimed. Insurance companies often challenge not only the severity of an injury, but also whether the accident caused it rather than degeneration, a preexisting condition, or an earlier accident.

What do you have to prove to meet New York’s serious injury threshold after the 2026 changes?

For an action governed by the amended law, an injured person must establish that the injury falls within at least one of the eight categories that remain in Insurance Law § 5102(d): 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, or significant limitation of use of a body function or system. The former category involving a medically determined nonpermanent injury that substantially curtailed customary daily activities for at least 90 of the first 180 days is no longer part of the statute for actions and proceedings commenced on or after May 26, 2026. The necessary proof therefore depends on which remaining category applies to the particular injury.

Do you need a permanent injury to recover pain and suffering after a New York car accident?

No. The current statute includes categories that expressly require permanence. Still, it also retains “significant limitation of use of a body function or system” as a separate category that does not expressly require permanence. That distinction is especially important after elimination of the 90/180 category. An injured person should not assume that a claim automatically fails because a doctor cannot characterize an injury as permanent. At the same time, the significant-limitation category should not be confused with ordinary temporary pain or minor restrictions. The medical and functional evidence must be examined to determine whether the nature and degree of the limitation satisfy the applicable legal standard.

Is an MRI enough to prove a serious injury in New York?

An MRI can provide important objective evidence of an injury, but an abnormal MRI finding does not necessarily establish by itself that the serious-injury threshold has been met. An MRI may document a herniated disc, torn rotator cuff, meniscus tear, ligament damage, or other structural condition. At the same time, additional medical evidence may be necessary to demonstrate the resulting functional limitation and connect the condition to the accident. For injuries being evaluated under the significant-limitation or permanent-consequential-limitation categories, the complete medical picture can include diagnostic imaging, clinical examinations, quantified restrictions, treatment history, surgical findings, neurological findings, prognosis, and a physician’s explanation of how the injury affects function. The defense may also contend that an MRI abnormality represents degeneration or a preexisting condition rather than traumatic injury, making causation a separate issue that should be addressed medically.

How can range-of-motion testing help prove a serious injury?

Measured range-of-motion restrictions can show the extent to which an injury has impaired the function of the spine, shoulder, knee, or another affected body part. In appropriate cases, a physician may compare the patient’s measured range of motion with normal values and document the degree of restriction found during the examination. That information can help move the medical record beyond a patient’s subjective description of pain by demonstrating an objectively assessed functional deficit. Range-of-motion measurements should still be considered as part of the complete medical record rather than as a stand-alone mathematical formula. The diagnosis, duration and degree of limitation, diagnostic studies, treatment, examination findings, prognosis, and relationship between the limitation and the accident can all affect the serious-injury analysis.

Can a herniated or bulging disc qualify as a serious injury under the new law?

A herniated or bulging disc can potentially support a serious-injury claim when the resulting condition satisfies one of the remaining statutory categories. Still, the MRI diagnosis alone does not necessarily resolve the issue. A spinal injury case may include evidence of restricted cervical or lumbar movement, radiculopathy, weakness, sensory deficits, positive clinical testing, EMG findings where medically appropriate, epidural or other injections, physical therapy, surgery, and continuing functional limitations. Insurers often argue that disc abnormalities are degenerative, existed before the collision, or do not produce a sufficiently significant limitation. For that reason, a strong spinal injury case generally requires counsel to examine both sides of the medical question: what objective evidence establishes the injury and functional loss, and what evidence connects those findings to the accident rather than another cause.

Can a torn rotator cuff qualify as a serious injury?

A rotator cuff tear may qualify when the injury and resulting limitation satisfy one of the statutory serious-injury categories. Shoulder cases can involve MRI evidence of a tear, measured restrictions in abduction or rotation, weakness, positive orthopedic testing, injections, physical therapy, arthroscopic surgery, operative findings, and continuing restrictions. Surgery can provide significant evidence concerning the nature of the underlying condition. Still, surgery does not eliminate the need to analyze the applicable statutory category and causation. An insurer may still argue that the tear was degenerative, preexisting, unrelated to the collision, or insufficiently limiting. Reviewing imaging, operative findings, pre-accident medical history, post-accident examinations, and the treating physician’s causation opinion can therefore be important.

Can a torn meniscus or knee injury meet the serious injury threshold?

A torn meniscus or other significant knee injury may satisfy the serious-injury threshold if the medical evidence establishes one of the categories remaining under § 5102(d). Depending on the circumstances, relevant evidence can include MRI findings, restricted flexion or extension, instability, swelling, gait changes, injections, physical therapy, arthroscopic surgery, operative findings, and documented difficulty walking, climbing stairs, kneeling, squatting, or performing other knee-related functions. As with other orthopedic injuries, connect the diagnosis to the resulting functional impairment. Where the claimant had preexisting arthritis or degenerative findings, medical evidence distinguishing traumatic injury or accident-related aggravation from the underlying condition can become especially important.

Does having surgery automatically prove a serious injury?

No. Surgery can be powerful evidence of the nature and severity of an injury, particularly when operative findings confirm structural damage, but undergoing surgery does not replace the legal requirement of establishing a qualifying serious injury under § 5102(d). The operative report, surgeon’s findings, reason surgery was medically indicated, postoperative condition, functional limitations, prognosis, and relationship between the treated condition and the accident may all be relevant. Defendants may still challenge causation by arguing that surgery addressed degeneration or a condition that existed before the collision. A serious-injury analysis therefore should consider surgery as part of the complete medical record rather than treating the procedure itself as an automatic statutory category.

What is a “significant limitation of use” under New York’s serious injury law?

“Significant limitation of use of a body function or system” remains one of the statutory definitions of serious injury after the 2026 amendment and may be particularly important for injuries that do not involve a fracture or another expressly identified category. The inquiry focuses on whether the injury produced a sufficiently meaningful limitation in the use of a body function or system, supported by appropriate medical evidence. Depending on the injury, physicians may document quantified restrictions, clinical findings, diagnostic abnormalities, neurological deficits, loss of strength, impaired movement, or other functional consequences. The analysis is not simply whether the person experienced pain after the accident. It concerns the medically supported nature and degree of the limitation resulting from the injury.

What is a permanent consequential limitation of use?

A permanent consequential limitation of use of a body organ or member is another serious-injury category that remains under Insurance Law § 5102(d). Unlike the significant-limitation category, this statutory category expressly requires permanence. Medical proof may therefore need to address not only the extent of the limitation but also the prognosis and basis for concluding that the limitation is permanent. Depending on the injury, evidence may include diagnostic studies, quantified restrictions, surgical findings, persistent symptoms and deficits despite treatment, and a physician’s assessment of the expected long-term functional consequences. A conclusory statement that an injury is permanent may be challenged if the underlying medical record does not adequately support that opinion.

What is the difference between permanent loss of use and permanent consequential limitation?

The statute treats permanent loss of use and permanent consequential limitation as separate categories. Permanent loss of use applies to the permanent loss of use of a body organ, member, function, or system. In contrast, permanent consequential limitation applies to a permanent consequential limitation of use of a body organ or member. Those terms should not be treated as interchangeable merely because both involve permanence. An attorney evaluating a serious-injury claim should identify the category actually supported by the medical evidence rather than simply alleging every category. The diagnosis, affected body part or function, extent of loss, objective findings, treatment history, and physician’s prognosis help determine which statutory definition may apply.

How important are a treating doctor’s medical reports?

Treating physicians’ records and reports can be extremely important because they document an injury’s progression from diagnosis through treatment, response, functional limitation, and prognosis. A useful medical record does more than repeatedly state that a patient has pain. It can identify objective findings, explain diagnostic studies, quantify restrictions when appropriate, document neurological or orthopedic abnormalities, describe treatment provided, address the patient’s response to that treatment, and explain the physician’s opinion concerning causation and prognosis. When a serious-injury motion is made, the medical proof may be scrutinized closely. Consistent, medically supported documentation developed during actual treatment can therefore become an important part of demonstrating what the injury did to the patient and why it satisfies the claimed statutory category.

Why does the timing of medical treatment matter after a car accident?

Prompt medical evaluation can help diagnose injuries and create a contemporaneous record connecting the patient’s symptoms and findings to the accident. Delays can create both medical and legal issues because an insurance company may argue that a substantial gap between the collision and initial treatment undermines causation or suggests that the condition was not severe. Legitimate explanations for delayed treatment include symptoms that appear or worsen after an accident, but the medical history should accurately document when symptoms began and how they progressed. Early treatment is not a substitute for objective evidence, nor does a delay automatically defeat a claim, but timing and continuity of treatment can matter when causation and severity are disputed.

Can stopping physical therapy hurt a serious injury case?

An unexplained cessation of treatment can become a defense issue, particularly when an injured person claims a continuing significant or permanent limitation. Insurance companies may argue that a lengthy treatment gap is inconsistent with the severity alleged. However, treatment may stop for legitimate reasons. A physician may determine that additional therapy will not produce further improvement, No-Fault benefits may be denied, treatment may shift from conservative care to injections or surgery, or the patient may have reached a point where continued therapy is medically unnecessary. The important issue is whether the treatment history and reason for discontinuation can be accurately explained and supported rather than leaving a significant gap unexplained.

What if the insurance company says my injuries are degenerative?

A finding of degeneration does not automatically establish that an accident caused no injury, but it can make medical causation a central dispute. Spinal discs, knees, shoulders, and other joints may show age-related or preexisting changes on diagnostic imaging even when a traumatic event also causes injury or aggravates an underlying condition. The medical analysis may therefore need to address whether the accident caused a new injury, worsened an existing condition, or produced symptoms and functional limitations that were not present beforehand. Prior medical records, earlier imaging, the absence or presence of pre-accident symptoms, post-accident diagnostic findings, operative observations, and physician opinions can all help evaluate causation.

What if I injured the same body part in an earlier accident?

A prior injury to the same body part does not automatically prevent recovery for a later accident, but the prior condition must be addressed rather than ignored. Defendants may obtain earlier medical records and compare prior complaints, imaging, diagnoses, treatment, and functional restrictions with the condition claimed after the new accident. The critical medical question may become whether the later collision caused a new injury, materially aggravated a preexisting condition, or produced additional functional loss. Comparing earlier and later diagnostic studies and having physicians address the differences can be particularly important. Complete and accurate disclosure of relevant prior treatment also lets counsel confront the causation defense directly, rather than allowing the insurer to characterize prior records without context.

Are complaints of pain enough to prove serious injury?

Complaints of pain alone generally should not be the foundation of a serious-injury case when the claimed statutory category turns on significant or permanent functional limitation. Pain is real and can have profound consequences, but the legal analysis focuses on whether the personal injury meets one of the definitions contained in § 5102(d). Medical findings that document the underlying injury and resulting impairment can therefore be critical. Depending on the condition, that evidence might include imaging, measured limitations, neurological deficits, orthopedic testing, surgical findings, weakness, or other medically documented abnormalities. The strongest presentation connects the patient’s symptoms to objective medical findings and then explains how those findings affect the relevant body function, organ, or member.

Do limitations on work, exercise, childcare, and daily activities still matter?

Yes. Evidence showing how an injury affects employment, household responsibilities, childcare, exercise, driving, walking, sleeping, lifting, and other daily activities can remain highly relevant even though the 90/180-day category has been eliminated. The difference is that inability to perform customary activities for 90 of the first 180 days is no longer an independent statutory serious-injury category in an action governed by the amended law. Functional evidence can still help demonstrate the real consequences of a medically established injury and can be relevant to damages. The medical evidence, however, must support one of the serious-injury categories that remains rather than relying solely on the duration of restrictions in daily life.

Can the insurance company require me to attend a medical examination?

During litigation, an injured plaintiff may be required to submit to a physical examination conducted by a physician selected by the defense under applicable New York disclosure procedures. The defense physician may evaluate range of motion, orthopedic or neurological findings, current symptoms, medical history, diagnostic studies, and whether the claimant has continuing limitations. The resulting report may allow the defendant to argue that an injury has resolved, is not significant or permanent, or is unrelated to the accident. Plaintiffs’ attorneys therefore compare defense medical findings with treating physicians’ records, diagnostic studies, operative reports, and other medical evidence rather than viewing the defense examination in isolation.

What evidence can help prove that the accident caused my injury?

Causation is often established through the combined medical and factual record, not a single document. Evidence may include emergency-room records, early complaints of pain, contemporaneous examinations, diagnostic imaging, specialist evaluations, operative findings, treating physicians’ opinions, prior medical records, prior imaging, and testimony concerning the person’s physical condition before and after the collision. Accident evidence can also matter, particularly when the defense argues that the mechanics of the impact could not have caused the claimed condition. The objective is to establish a medically supported connection between the collision, the diagnosed injury, and the functional limitation rather than merely showing that a medical condition was discovered sometime after the accident.

Can I recover pain and suffering if I prove a serious injury?

Establishing a serious injury satisfies an essential threshold for recovering non-economic damages in an automobile action governed by Article 51. Still, it does not by itself establish liability or determine the amount of compensation. The plaintiff must still prove the defendant was legally responsible for the accident and that the claimed injuries resulted from it. The 2026 reforms also changed comparative fault for Article 51 actions commenced on or after May 26, 2026. Under the amended CPLR § 1411, a claimant’s culpable conduct bars recovery in such an action if it is greater than the culpable conduct of the person against whom recovery is sought, or greater than the combined culpable conduct of the persons against whom recovery is sought. Serious injury, fault, medical causation, damages, and insurance coverage therefore remain distinct issues that must be developed together.

Why is proving serious injury different after the 2026 law change?

The principal statutory change is that a claimant can no longer rely upon the former 90/180-day category in an action or proceeding commenced on or after May 26, 2026. A person who experienced substantial restrictions for several months following an accident must instead establish one of the eight serious-injury categories that remain. This makes it especially important to identify the correct statutory category early, preserve diagnostic and treatment records, document functional limitations accurately, address causation and preexisting conditions, and anticipate the medical arguments the insurer is likely to raise. The reform does not create a rule that every injury must be permanent, but it does eliminate a distinct route that previously allowed nonpermanent injuries to qualify.

Why Choose Greenstein & Pittari, LLP?

Proving serious injury after New York’s 2026 automobile law changes requires more than collecting an MRI report and documenting pain complaints. The medical evidence must be evaluated against the statutory category actually being claimed, while potential defenses involving degeneration, prior accidents, treatment gaps, causation, functional limitations, and medical examinations must be anticipated before they become obstacles to the case.

Greenstein & Pittari, LLP has decades of experience representing people seriously injured in motor vehicle accidents throughout New York. Our attorneys investigate how an accident happened, preserve critical evidence, review medical and diagnostic records, examine prior medical history where relevant, investigate available liability, excess, umbrella, UM, and SUM insurance coverage, and develop the evidence needed to confront serious-injury and causation defenses raised by insurance companies.
