Understanding CRPS Claims in NSW CTP Law
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 accident in New South Wales is a complex injury that may qualify for compensation under the Compulsory Third Party (CTP) insurance scheme. Insurers assess liability based on the Motor Accident Injuries Act 2017 (MAIA), which governs all CTP claims in NSW. To determine liability, insurers examine whether the injury arose from a motor vehicle accident, whether the claimant was injured as a result of a motor vehicle, and whether the injury is recognised under the CTP scheme. CRPS is not automatically compensable; it must be established as a result of the accident and supported by medical evidence that meets the criteria set out in the Motor Accident Guidelines.
How Insurers Evaluate Medical Evidence for CRPS
Insurers assess liability for CRPS by reviewing medical evidence that confirms the injury occurred as a direct result of the motor accident. The Motor Accident Guidelines require that a diagnosis of CRPS must be supported by clinical signs such as changes in skin colour, temperature, swelling, or motor dysfunction, and must not be attributable to another cause. Insurers will consider reports from medical practitioners, including pain specialists and neurologists, to determine if the symptoms are consistent with CRPS and not due to pre-existing conditions or psychological factors. The presence of a spinal nerve-root injury with neurological signs other than radiculopathy may still fall within the definition of a soft-tissue injury under the Guidelines, which is relevant for threshold injury assessment.
Legal Boundaries for Liability Determination
Under the MAIA, insurers are not required to accept liability based on fault alone. The CTP scheme provides compensation regardless of fault, but liability for damages is not automatic. Insurers assess whether the claimant’s injuries are eligible for treatment and care benefits, weekly income payments, or damages. For CRPS, the insurer will determine whether the injury meets the threshold for damages under section 3.11 of the MAIA. This requires that the injury be a threshold injury, which includes certain soft-tissue injuries, and that it results in a permanent impairment of at least 10% of the whole person. If the injury does not meet the threshold, the claimant may still receive treatment and care benefits and weekly income payments, but not damages.
Key Evidence That Influences Liability Assessments
Insurers rely on several types of evidence when assessing liability for CRPS claims. These include:
- Medical records from the time of the accident and subsequent treatment, including imaging reports and neurological assessments
- Statements from treating medical practitioners detailing the onset and progression of symptoms
- Documentation of any prior injuries or conditions that may have contributed to the development of CRPS
- Accident reports, including police reports or CTP accident forms completed at the scene
- Photographs of the accident scene, vehicle damage, or injuries sustained
- Witness statements, if available
Insurers may also request an independent medical assessment to verify the diagnosis and assess the severity and permanency of the condition. The claimant’s compliance with treatment and rehabilitation plans may also be considered in determining the reasonableness of the claim.
Time Limits and Procedural Requirements
There is a time limit to make a claim for compensation under the CTP scheme. A claim must be made within three years of the accident date. Insurers may also apply a 52-week rule where a claimant’s only injuries are threshold injuries. Under this rule, treatment and care benefits and weekly income payments are generally limited after 52 weeks, unless the claimant has a permanent impairment that exceeds 10% of the whole person. This rule applies to CRPS if it is classified as a soft-tissue injury and no other injury exceeds the threshold.
When to Seek Independent Legal Advice
The assessment of liability for CRPS claims can be highly technical, particularly when evaluating medical evidence and applying the Motor Accident Guidelines. Insurers may dispute the diagnosis, the causal link to the accident, or the level of impairment. If a claim is denied or the insurer offers a settlement that does not reflect the full extent of the injury, it may be necessary to seek independent legal advice. A legal professional can assist in reviewing medical evidence, challenging insurer decisions, and pursuing a claim for damages if the threshold for damages is met.
Hypothetical Example: Assessing a CRPS Claim
A 42-year-old pedestrian was struck by a car in a car park in Sydney in June 2024. The individual reported immediate pain in the left leg and was diagnosed with CRPS in November 2024 after a neurologist confirmed signs of sympathetic nervous system dysfunction. The insurer reviewed the medical evidence and accepted that the injury was related to the accident but disputed the severity and permanency. The claimant underwent a second medical assessment, which confirmed a 15% whole person impairment. The insurer offered a settlement based on treatment and care benefits only. The claimant sought legal advice and successfully negotiated a damages claim under the MAIA.
