Serious Injury Threshold in NSW CTP Claims

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

Under New South Wales law, a serious injury for CTP claims is defined by the State Insurance Regulatory Authority (SIRA) as an injury that exceeds the 'threshold injury' under the Motor Accident Injuries Act 2017. This means the injury must be more than a minor soft tissue injury, such as a whiplash or bruise, and must meet specific clinical criteria outlined in the Motor Accident Guidelines. Claimants in Ashfield must understand this distinction to avoid errors in assessing their injury severity.

Common Mistakes in Assessing Serious Injury Thresholds

Claimants often make errors when determining whether their injury meets the serious injury threshold. One frequent mistake is assuming that any injury requiring medical treatment qualifies as serious. In reality, the injury must meet SIRA’s clinical criteria, such as prolonged neurological signs or significant functional impairment. Another error is failing to document injuries properly, which can weaken a claim. For example, not recording symptoms like persistent headaches or mobility issues may lead to the injury being classified as a threshold injury instead of serious.

Practical Steps to Avoid Errors in CTP Claims

  • To avoid mistakes, claimants should:
  • Gather comprehensive medical records, including diagnostic imaging and specialist reports.
  • Document all symptoms, even if they seem minor, and track their progression.
  • Preserve evidence of the accident, such as police reports, witness statements, and photographs of the scene.
  • Seek early medical attention to ensure injuries are recorded accurately. These steps help establish that the injury exceeds the threshold and supports a claim for additional compensation.

Time Limits and When to Seek Advice

NSW CTP claims must be submitted within 52 weeks of the accident if the injury is classified as a threshold injury. However, for serious injuries, the time limit is not strictly enforced, though delays can complicate recovery of benefits. Claimants should consult a legal professional if they are unsure about their injury’s classification or face disputes from insurers. In Ashfield, legal experts can help navigate the process and ensure claims meet SIRA’s requirements.

Example of a Serious Injury Claim

Consider a claimant who suffered a fractured wrist and ligament damage in a car accident. While the wrist injury might initially seem minor, if it caused chronic pain and limited mobility, it could meet the serious injury threshold. Proper documentation of symptoms and medical treatment is essential to avoid misclassification.
