Complex Regional Pain Syndrome Claims in New York

How Do You Prove Complex Regional Pain Syndrome in a New York Claim?

With the signs, not the symptoms. That distinction is the entire case.

CRPS is treated by insurers as the most subjective diagnosis in injury litigation, and the accepted diagnostic standard is built the opposite way. The Budapest Criteria require a clinician to observe physical findings, not merely to record what a patient reports.

Temperature difference between limbs. Color change. Swelling. Sweating asymmetry. Loss of range of motion. Changes in hair, nail, and skin.

Those are observable, measurable, and photographable, and they are exactly what New York's threshold asks a medical opinion to rest on.

The Budapest Criteria, and Why They Were Written This Way

The International Association for the Study of Pain adopted the criteria in 2004 to replace an earlier framework that was highly sensitive and poorly specific, meaning it caught nearly every real case and a good many conditions that were not CRPS at all.

The revision kept the sensitivity and sharply improved the specificity by adding motor and trophic features and by putting weight on clinician-observed signs rather than on patient-reported symptoms alone.

The Four Categories

Sensory. Hyperesthesia, meaning heightened sensitivity, and allodynia, meaning pain from something that should not hurt, such as a bedsheet or a light touch.

Vasomotor. Temperature asymmetry between the affected limb and the other one, and skin color changes or asymmetry.

Sudomotor and edema. Swelling, sweating changes, and sweating asymmetry between the limbs.

Motor and trophic. Decreased range of motion, motor dysfunction including weakness, tremor, and dystonia, and trophic changes affecting hair, nails, and skin.

What the Diagnosis Requires

Continuing pain disproportionate to the inciting event. At least one symptom reported in three of the four categories. At least one sign observed at the time of evaluation in two or more categories. And no other diagnosis that better explains the findings.

That last requirement is the one people underestimate. A properly made CRPS diagnosis is a diagnosis of exclusion as well as inclusion, which means the treating physician has already ruled out the alternatives the defense will propose.

Why This Diagnosis Satisfies New York's Objective Basis Requirement

CRPS is not one of the eight categories in Insurance Law § 5102(d), so a motor vehicle claim runs through permanent consequential limitation of use of a body organ or member, or significant limitation of use of a body function or system.^[1]

New York requires a threshold opinion to have an objective basis and to compare the plaintiff's limitations to normal function. Subjective complaints of pain, standing alone, are insufficient.

Which is precisely why the Budapest framework fits. Every sign category produces something recordable:

• Temperature asymmetry is measured with an infrared thermometer and recorded as a number.
• Color change is photographed, and side-by-side images of two hands are among the most persuasive exhibits in this practice.
• Edema is measured by circumference and compared to the other limb.
• Range of motion is measured with a goniometer and stated against the normal value.
• Trophic changes in nail growth, hair distribution, and skin texture are visible and documented.
• Motor dysfunction including tremor and dystonia is observable and can be recorded.

Supportive studies exist and are worth having where a treating physician orders them, including three-phase bone scintigraphy and autonomic testing. None of them is required for the diagnosis, and a defense expert who treats a negative bone scan as ruling out CRPS is misstating what the criteria say. The diagnosis is clinical, and the clinical findings are the objective proof.

Our page on proving a serious injury under Insurance Law § 5102(d) covers all eight categories and how each is documented.

Type I, Type II, and How CRPS Starts

The condition is divided by whether an identifiable nerve injury is present, and the distinction matters to both the medicine and the case.

Type I and Type II

Type I, historically called reflex sympathetic dystrophy, follows an injury without a confirmed nerve lesion. Type II, historically causalgia, follows a documented nerve injury. Type II is often the more straightforward case to present, because there is an identified lesion connecting the trauma to the condition.

Type I is more common and is where the disbelief problem concentrates, because the disproportion between the original injury and the resulting condition is precisely what makes people doubt it. A wrist fracture that heals in eight weeks and leaves a person with a burning, discolored, unusable hand is the classic presentation, and the mismatch is a feature of the disease rather than a reason to question it.

The Treatment Ladder, and What Each Step Establishes

Physical and occupational therapy first, then medication management, then sympathetic nerve blocks, then in some cases a spinal cord stimulator trial and implantation, and in a small number of cases intrathecal drug delivery.

Each step up that ladder is a documented medical judgment that the condition was severe enough to justify a more invasive intervention. A person who has undergone a stimulator trial has a record that speaks for itself about severity, which is why the treatment history in a CRPS case does evidentiary work beyond the treatment itself.

Early intervention also matters clinically. Delay in diagnosis is associated with worse outcomes, which is one reason a case where the condition was missed for months carries its own set of questions about who should have recognized it.

What Drives Value in a New York CRPS Claim

We do not publish an average CRPS settlement figure. This is a condition whose severity ranges from a limb that recovers substantially to a person who cannot tolerate clothing on an extremity, and an average across that range tells nobody anything.

• Which limb, and whether it is dominant. A dominant hand affects work and independence differently from a foot, and both differ from a lower limb that ends the ability to stand for a shift.
• Whether the condition spread. Spread to a contralateral or distant limb is a recognized feature and it substantially raises severity.
• How far up the treatment ladder the case went. Blocks, a stimulator trial, an implanted device, or intrathecal therapy each mark a level of severity in the record.
• Permanence and trajectory. Whether a treating physician expects the condition to persist, and whether function has been improving or declining.
• Work capacity. Whether the person can hold their occupation, hold any occupation, or neither. In CRPS this is frequently the largest economic component.
• Daily function. Dressing, driving, sleeping, and the ability to tolerate contact, which is what allodynia actually means day to day.
• Psychiatric sequelae. Depression and anxiety are common consequences of chronic severe pain and are compensable as part of the injury.
• Documentation quality. Whether the signs were recorded contemporaneously with measurements and photographs, or described only in narrative.

New York places no statutory cap on pain and suffering, which matters more in this category than in almost any other, because pain is the injury. What operates instead is appellate review under CPLR § 5501(c), which asks whether an award deviates materially from what would be reasonable compensation.^[2]

What a New York CRPS Claim Can Recover

Once the threshold is met, everything is available, and in this category the future care number is substantial.

• Medical expenses above basic economic loss. Pain management, blocks, medication, therapy, and device implantation and maintenance.
• Future medical care. Including stimulator battery replacement and revision, and ongoing pain management across a lifetime.
• Lost earnings and lost earning capacity. Where the affected limb ends an occupation, established by a vocational analysis.
• Pain and suffering. Uncapped in New York, and the dominant component in most CRPS cases.
• Loss of enjoyment of life. The activities, contact, and ordinary comfort the condition removes.
• Home and personal assistance. Where the person cannot manage dressing, driving, or household tasks.
• Loss of consortium. A spouse's separate claim.

Where the CRPS followed a motor vehicle collision, Insurance Law § 5104(a) excludes basic economic loss from the liability claim, so the first layer of medical bills and lost wages paid by no-fault sits outside the case against the at-fault driver. Where it followed a fall, a workplace injury, or a surgical complication, no threshold applies at all and pure comparative fault governs. Our national page on CRPS settlement values covers the condition outside the New York framework.

 

The Hardest Part of a CRPS Claim Is Not the Medicine

The hardest part of a CRPS claim is usually not the medicine. It is that the person has already spent a year being questioned.

• An office in the courthouse district. We work from 305 Broadway in Lower Manhattan, minutes from the courts where these cases are tried.
• The record gets built around signs. Measured temperature, photographed color and trophic change, recorded circumference, and range of motion against normal, because those are what an objective basis means.
• The diagnosis is presented as the criteria are written. Including the exclusion element, so a defense expert cannot treat a negative bone scan as though it ended the question.
• The treatment ladder is used as evidence. Each escalation is a physician's judgment about severity, on the record.
• Future care is priced properly. Device maintenance, revision, and lifetime pain management, rather than a snapshot of what has been spent.
• Credentials you can check yourself. Best Lawyers in America, Super Lawyers, the Million Dollar Advocates Forum, and the National Trial Lawyers all publish their lists, so none of this rests on our own say-so.
• A 98 percent recovery rate, built on saying no. Across more than 40,000 cases we have recovered over $100 million, and the rate holds because we decline the files we do not believe in.
