Understanding CRPS and CTP Liability in NSW
Chronic regional pain syndrome (CRPS) following a motor vehicle accident in New South Wales is recognised as a serious and complex injury under the Motor Accident Injuries Act 2017 (MAIA). Insurers assess liability for CRPS claims based on the legal framework established by SIRA and the MAIA, not on the presence of a visible injury. Liability is determined by whether the accident caused the injury, regardless of fault, under the CTP scheme. This means that even if the injured person was not at fault, the insurer must still assess whether the accident caused or contributed to the development of CRPS.
How Insurers Evaluate CRPS Claims
Insurers assess CRPS claims by examining medical evidence, the timing of symptom onset, and whether the injury is directly linked to the accident. The Motor Accident Injuries Regulation 2017 and SIRA’s Motor Accident Guidelines require that a diagnosis of CRPS must be supported by clinical findings, including changes in skin colour, temperature, swelling, or motor dysfunction. Insurers will review reports from medical practitioners, including pain specialists and neurologists, to determine if the symptoms are consistent with CRPS and not attributable to pre-existing conditions.
A key factor in assessment is whether the CRPS developed within a reasonable timeframe after the accident. Insurers will also consider whether the injury meets the threshold for a claim under the MAIA, particularly if the claim seeks damages. The presence of a spinal nerve-root injury with neurological signs other than radiculopathy may still qualify as a soft-tissue injury under the Guidelines, which can affect eligibility for damages.
Evidence That Matters in CRPS Claims
The strength of a CRPS claim depends on the quality and consistency of medical evidence. Insurers will review:
- Detailed medical records from the accident and follow-up appointments
- Diagnostic imaging (MRI, bone scans) showing changes consistent with CRPS
- Reports from pain management specialists or neurologists confirming the diagnosis
- Documentation of functional impairment, including inability to work or perform daily activities
- A timeline linking the onset of symptoms to the accident
Photographs of the affected limb, witness statements about changes in behaviour or mobility, and records of treatment such as nerve blocks or physical therapy may also be considered. Insurers may request a second medical assessment to verify the diagnosis and its connection to the accident.
Time Limits and Procedural Requirements
A claim for compensation related to CRPS must be made within the time limits set by the MAIA. While the CTP scheme provides automatic access to treatment and care benefits, claims for damages must be filed within two years of the accident. This deadline applies regardless of when symptoms first appeared or were diagnosed. Failure to meet this deadline may prevent a claim for damages, although treatment and care benefits may still be available.
Insurers may also assess whether the injured person has taken reasonable steps to manage the injury, including seeking treatment and providing information. Delays in reporting symptoms or failing to attend medical appointments may be considered in the assessment of the claim, but they do not automatically invalidate it.
Disputes and Seeking Advice
If an insurer denies a claim or offers less than expected, the injured person may request a review under the SIRA dispute resolution process. This includes a formal review by SIRA or, if unresolved, a referral to the NSW Civil and Administrative Tribunal (NCAT). The process allows for the submission of additional medical evidence and expert opinion.
Given the complexity of CRPS and the medical and legal standards involved, individuals are strongly encouraged to seek independent advice before making a claim or responding to an insurer’s assessment. The nature of chronic pain and its long-term impact on daily life and employment require careful documentation and legal understanding.
Hypothetical Example
A 42-year-old driver in Sydney was involved in a rear-end collision in a car park in February 2025. Within six weeks, they developed severe pain, swelling, and stiffness in their left leg, which was later diagnosed as CRPS by a pain specialist. The medical evidence showed no pre-existing condition and a clear link between the accident and symptom onset. The insurer initially questioned the diagnosis but accepted the claim after a second opinion confirmed the diagnosis and its connection to the accident.
