Understanding Chronic Regional Pain Syndrome in NSW CTP Claims
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 NSW is now governed by the Motor Accident Injuries Act 2017 (MAIA), which introduced significant changes to how compensation is assessed and awarded. Prior to 1 December 2017, claims were governed by the Motor Accidents Compensation Act 1999 (MACA), which had different thresholds and processes for injury assessment. The 2017 reforms established a new framework focused on early intervention, medical evidence, and a structured approach to determining injury severity and entitlements.
Under the current MAIA framework, CRPS is treated as a potential threshold injury if it results in a whole person impairment (WPI) of 10% or more. However, the law does not automatically categorise CRPS as a threshold injury. The determination depends on clinical findings, including the presence of neurological signs, and whether the injury meets the definition in the Motor Accident Guidelines. This means that not all cases of CRPS will qualify for damages, and entitlements are not guaranteed simply because a diagnosis has been made.
Key Legal Changes Since 2017
The 2017 reforms introduced several changes that affect how CRPS claims are processed in Greater Sydney and across NSW. The most significant change is the introduction of a formal threshold for damages eligibility. A claimant must have a WPI of 10% or more due to a permanent impairment caused by the accident to be eligible for damages. This applies regardless of the nature of the injury, including CRPS.
Another major change is the 52-week limit on treatment and care benefits and weekly income payments for claimants whose only injuries are threshold injuries. If a person’s only injuries are threshold injuries (including certain forms of CRPS), benefits are generally capped at 52 weeks from the date of the accident. This means that long-term CRPS cases may not receive ongoing treatment and care benefits unless they can demonstrate that their injury exceeds the threshold or that they have a non-threshold injury that is permanent and severe.
The reforms also strengthened the role of medical evidence. Claims for CRPS now require objective clinical evidence, including imaging, nerve conduction studies, and assessments by qualified medical practitioners. The Motor Accident Guidelines set out specific criteria for diagnosing CRPS, including the presence of signs such as swelling, skin changes, or motor dysfunction that are not explained by other conditions.
Practical Steps and Evidence That Matter
If you have been diagnosed with CRPS following a motor vehicle accident in Greater Sydney, the following steps and evidence are critical to supporting your claim under the MAIA framework:
- Seek medical assessment from a specialist in pain management or neurology as soon as possible. Early diagnosis and documentation improve the strength of your claim.
- Obtain a formal assessment of your whole person impairment (WPI) from a qualified medical assessor registered under the MAIA.
- Preserve all medical records, including imaging reports, treatment notes, and correspondence with your GP or specialist.
- Document any loss of income, changes in daily function, and the impact on your family life. This supports claims for weekly income payments and damages.
- Report the accident to the insurer of the at-fault vehicle within a reasonable time. While there is no strict deadline for notification, delays may affect the insurer’s ability to investigate and respond.
A hypothetical example: A 38-year-old office worker in Sydney was involved in a rear-end collision in the Eastern Suburbs in June 2024. She developed CRPS in her right leg, with persistent pain, swelling, and reduced mobility. She obtained a WPI assessment showing 12% impairment due to the injury. Because her only injury was CRPS and it met the threshold criteria, she became eligible for damages. However, her treatment and care benefits were limited to 52 weeks under the MAIA, and she had to apply for a review if she needed ongoing treatment beyond that period.
Time Limits and Dispute Options
There are time limits that apply to CTP claims in NSW. You must generally start a claim for damages within three years of the accident date. For claims involving treatment and care benefits, the time limit is also three years from the accident date, but it may be extended if you were under 18 at the time of the accident.
If your claim is denied or you disagree with the insurer’s assessment of your injury, you may request a review or apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination. The tribunal can review medical evidence, assess WPI, and decide whether damages are payable.
When to Seek Independent Advice
The legal framework for CRPS claims under the MAIA is complex and fact-specific. Whether your injury qualifies as a threshold injury, whether you are entitled to damages, and how long benefits will be paid all depend on medical evidence, the nature of the injury, and the timing of treatment and claims. These factors vary significantly between individuals, even in Greater Sydney.
