Traumatic brain injury, scheme eligibility basics (Auburn)

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 vehicle accident in Auburn, you may be eligible for compensation under the NSW Compulsory Third Party (CTP) scheme. This guide explains how TBI claims are assessed under the scheme, what evidence is needed, and how to determine if your injury qualifies.

NSW CTP rules for traumatic brain injuries

Under the Motor Accident Injuries Act 2017, the NSW CTP scheme covers injuries resulting from motor vehicle accidents. Traumatic brain injuries are defined as injuries to the brain caused by an external force, such as a blow or jolt. Examples include concussions, contusions, and diffuse axonal injuries.

SIRA (State Insurance Regulatory Authority) evaluates TBI claims based on clinical evidence. To qualify, your injury must meet the 'threshold injury' criteria outlined in the Motor Accident Guidelines. This includes injuries that result in neurological signs, such as changes in mental status, memory loss, or coordination issues. A spinal nerve-root injury producing neurological signs may also qualify under specific conditions.

Evidence and documentation for TBI claims

To support a TBI claim, you'll need:

  • Medical records confirming the injury and its cause
  • A diagnosis of traumatic brain injury from a medical practitioner
  • Evidence linking the injury to the motor vehicle accident
  • Documentation of any ongoing symptoms or treatment

SIRA requires a detailed medical report from a qualified specialist. If your injury results in long-term effects, such as cognitive impairment or mobility issues, this will impact your eligibility for benefits like weekly income payments or treatment and care benefits.

Time limits and dispute resolution

Claims must be filed within 52 weeks of the accident if you're seeking statutory benefits like weekly payments. However, if your injury is not a 'threshold injury, ' you may still pursue a common law damages claim through the courts. Time limits for such claims are longer but depend on the specific circumstances.

If you disagree with SIRA's assessment, you can request a review or seek independent medical opinion. Disputes often arise when the injury's severity or long-term impact is contested. It's important to act promptly to preserve your rights.

When to seek legal advice

The NSW CTP scheme has strict rules about eligibility and deadlines. If your injury involves complex medical evidence or disputes over the extent of your damage, consulting a solicitor experienced in CTP claims can help ensure you receive the support you're entitled to.
