Understanding Traumatic Brain Injury Claims in NSW

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).

If you've suffered a traumatic brain injury (TBI) in a motor accident in New South Wales, understanding how insurers assess your claim is critical. The NSW Compulsory Third Party (CTP) scheme provides statutory benefits, but insurers evaluate claims based on the Motor Accident Injuries Act 2017 and SIRA guidelines. This article explains how insurers determine eligibility, what evidence matters, and how rural areas like Armidale are treated under the scheme.

Key Factors in TBI Claim Assessments

NSW insurers assess TBI claims by evaluating:

  • Medical evidence: Detailed records confirming the injury, including neurological signs, imaging, and specialist reports. SIRA guidelines specify that injuries must meet the 'threshold injury' definition, which includes spinal nerve-root injuries producing neurological signs.
  • Nature of the injury: Whether the TBI is classified as a 'threshold injury' under the Motor Accident Injuries Act 2017. This requires a whole-person impairment assessment by a medical practitioner.
  • Causation: Proof that the injury resulted from the motor accident, not a pre-existing condition or unrelated incident.
  • SIRA's role: SIRA assesses claims using its published guidelines, which outline how to determine the severity of injuries and the appropriate benefits.

How SIRA Guidelines Apply in Rural NSW

In rural areas like Armidale, insurers apply the same SIRA guidelines as in urban centres. For example, a 2023 case in Armidale involved a cyclist with a TBI assessed under SIRA's neurological criteria. The insurer required detailed MRI scans and a neurologist's report to confirm the injury met the threshold definition. This highlights the importance of thorough medical documentation, regardless of location.

Common Reasons for Claim Rejection or Reduction

Insurers may reject or reduce TBI claims for these reasons:

  • Lack of medical evidence: Claims without detailed medical records or specialist reports are often denied.
  • Dispute over injury classification: If the insurer disputes whether the injury qualifies as a 'threshold injury, ' benefits may be limited.
  • Contributory fault: If the claimant is found to have contributed to the accident, benefits may be reduced under the Act.
  • Exceeding 52 weeks: After 52 weeks, weekly benefits for threshold injuries are generally limited, unless the injury is classified as a 'major injury' under SIRA guidelines.

Practical Steps to Support Your Claim

To strengthen your TBI claim:

  • Seek immediate medical attention: Document all treatments, including consultations with neurologists and rehabilitation specialists.
  • Preserve accident details: Gather police reports, witness statements, and photographs of the scene.
  • Submit SIRA's required forms: Complete the 'Claim Form' and 'Medical Report Form' accurately, ensuring all injury details are clearly described.
  • Request a medical assessment: If the insurer disputes the injury's severity, request an independent assessment by a SIRA-approved medical practitioner.

Time Limits and Dispute Options

You have 5 years from the accident date to make a claim under the CTP scheme. If your claim is denied, you can:

  • Submit a review request to SIRA within 28 days of receiving the decision.
  • Seek legal advice if the insurer refuses to reconsider the claim or if you believe the assessment is incorrect.

When to Seek Legal Advice

Consult a solicitor if:

  • Your claim is rejected or reduced.
  • You're unsure how to respond to an insurer's request for more information.
  • You need help challenging a decision under the Motor Accident Injuries Act 2017.
