A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).
Chronic regional pain syndrome (CRPS) following a motor vehicle accident in New South Wales is recognised under the Motor Accident Injuries Act 2017 as a potential injury eligible for compensation through the Compulsory Third Party (CTP) scheme. While CRPS is not automatically classified as a threshold injury, it may qualify for statutory benefits and, in some cases, damages if it results in a whole person impairment of 10% or more. The assessment of CRPS in NSW CTP claims is governed by the Motor Accident Injuries Regulation 2017 and the Motor Accident Guidelines issued by the State Insurance Regulatory Authority (SIRA). These documents set out the medical and evidentiary standards that must be met to establish a claim, including the need for objective clinical signs and a documented progression of symptoms over time. This article outlines the legal framework, required evidence, and practical considerations for claimants pursuing compensation for CRPS in NSW.
How CRPS is Recognised in NSW CTP Claims
Under the Motor Accident Injuries Act 2017, a claim for compensation for CRPS must be supported by medical evidence that demonstrates the condition is a direct result of the motor accident. CRPS is a complex neurological disorder that typically develops after trauma, often involving a limb, and is characterised by severe, prolonged pain that is disproportionate to the initial injury. SIRA’s Motor Accident Guidelines require that a diagnosis of CRPS be made by a medical practitioner with appropriate expertise, and that it be supported by clinical findings such as changes in skin colour, temperature, swelling, or motor dysfunction. Importantly, the presence of radiculopathy, a condition involving nerve root irritation, may affect classification under the threshold injury provisions, but CRPS itself is not automatically excluded from benefits.
Evidence Required to Support a CRPS Claim
To establish a valid CTP claim for CRPS, claimants must provide a comprehensive record of medical assessment and treatment. Key evidence includes:
- A formal diagnosis from a medical practitioner, preferably a pain specialist or neurologist, supported by imaging (such as MRI or bone scan) and nerve conduction studies.
- A treatment history detailing interventions such as physical therapy, medication, nerve blocks, or psychological support.
- Documentation of functional impairment, including limitations in daily activities, work capacity, or mobility, as recorded in medical reports.
- A chronology of symptoms showing a progression consistent with CRPS, particularly if symptoms began shortly after the accident and have persisted beyond the expected recovery period.
SIRA emphasises that claims based on CRPS must not rely solely on self-reported pain. Objective evidence of physiological change is required to meet the standard for compensation under the CTP scheme. Claimants should ensure all medical reports are clear, contemporaneous, and include a direct link between the accident and the onset of symptoms.
How SIRA Assesses CRPS Compared to Other Injuries
SIRA’s assessment of CRPS differs from that of more common soft-tissue injuries such as whiplash. While soft-tissue injuries are subject to a threshold test under the Motor Accident Injuries Act 2017, CRPS is not categorised as a threshold injury unless it is determined to be a soft-tissue injury with no objective evidence of structural damage. However, if a claimant’s only injuries are deemed threshold injuries, weekly benefits and treatment and care benefits are generally limited to 52 weeks under section 4.4 of the Act. This limitation does not apply if the CRPS results in a whole person impairment of 10% or more, which may allow for ongoing benefits and a claim for damages.
SIRA uses the Whole Person Impairment (WPI) assessment process to determine whether a claimant’s CRPS has caused a permanent impairment. The assessment is conducted by an independent medical assessor and considers the extent of functional loss, pain severity, and impact on daily life. A WPI of 10% or more may qualify the claimant for damages, which include compensation for pain and suffering, loss of enjoyment of life, and future care needs.
Common Challenges in Proving CRPS Claims
Proving a CRPS claim in NSW CTP proceedings presents several challenges. The most frequent issue is the lack of objective medical evidence at the time of the accident. Because CRPS often develops weeks or months after the incident, initial medical reports may not record symptoms, making it difficult to establish a direct link to the accident. Another common challenge is the potential for dispute over the causation of symptoms, particularly if the claimant has a pre-existing condition or has experienced other trauma.
Claimants may also face delays in receiving a formal assessment due to the need for specialist referrals or the complexity of the medical evidence. SIRA advises that claimants should notify their insurer as soon as possible after the accident, even if symptoms are not immediately apparent, to preserve the right to claim. Failure to report the injury promptly may result in a delay in benefit payments or a challenge to the claim’s validity.
Practical Steps for Claimants
The following steps are recommended for individuals pursuing a CTP claim for CRPS in NSW:
- Seek medical assessment from a specialist as soon as symptoms develop, even if they are mild.
- Keep a daily journal of symptoms, treatment, and functional limitations.
- Preserve all medical records, including correspondence with healthcare providers and treatment plans.
- Report the injury to the insurer within a reasonable time, ideally within 30 days of the accident.
- Request a formal WPI assessment if the injury persists beyond 12 weeks.
A hypothetical example: A 42-year-old Sydney woman was involved in a rear-end collision in Chatswood in April 2024. She initially reported neck and shoulder pain but developed severe, burning pain in her left arm six weeks later. After referral to a pain clinic, she was diagnosed with CRPS Type I. Her medical records, including MRI scans and nerve conduction studies, were used to support a WPI of 12%. She was able to claim ongoing treatment and care benefits and, after a successful WPI assessment, pursue damages for pain and suffering.
Time Limits and Dispute Resolution
There is no fixed deadline for making a CTP claim in NSW, but delays may affect the availability of evidence or the insurer’s ability to investigate. SIRA advises that claims should be made as soon as possible after the accident. If a claim is disputed, the claimant may seek resolution through the CTP dispute resolution process or, if necessary, apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination.
