Traumatic Brain Injury Claims Under NSW CTP Scheme

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 New South Wales, you may be eligible for compensation through the NSW Compulsory Third Party (CTP) scheme. The Motor Accident Injuries Act 2017 and SIRA guidelines define the criteria for TBI claims, distinguishing them from other injuries. This article explains the key factors that determine eligibility, the evidence required, and time limits for claims.

What Injuries Qualify as Traumatic Brain Injuries?

A traumatic brain injury under the CTP scheme refers to an injury caused by an external force, such as a blow or jolt to the head. The injury must result in a neurological condition that affects brain function. SIRA guidelines clarify that injuries meeting the 'threshold injury' definition under the Motor Accident Injuries Act 2017 may qualify. This includes injuries like concussions, contusions, or diffuse axonal injury that produce neurological signs, such as memory loss, confusion, or changes in behavior.

The spinal nerve-root qualification is critical: a spinal nerve-root injury producing neurological signs other than radiculopathy may still fall within the soft-tissue definition. However, radiculopathy requires specific clinical signs as outlined in the Motor Accident Guidelines.

How Is TBI Eligibility Determined for CTP Claims?

Eligibility depends on whether the injury meets the 'threshold injury' criteria. Under the Motor Accident Injuries Act 2017, a threshold injury is defined as an injury that results in a whole person impairment (WPI) of 10% or more, or a neurological injury that meets specific clinical signs. For TBI claims, the injury must also result in a loss of function, such as difficulty concentrating, memory impairment, or speech issues.

If your TBI does not meet the threshold injury criteria, you may still be eligible for statutory benefits like weekly income payments or treatment and care benefits. However, these benefits are generally limited after 52 weeks if the injury is not a threshold injury.

Documentation Required to Prove TBI for CTP Claims

To support your claim, you must provide evidence of the injury and its impact. Key documentation includes:

  • Medical records confirming the TBI diagnosis and treatment
  • A report from a medical practitioner detailing the injury's effects
  • Accident reports and witness statements
  • Photographs of the accident scene
  • Income records to establish loss of earnings

SIRA requires that your claim demonstrates a clear link between the accident and the TBI. Medical professionals must also confirm that the injury meets the scheme's definition of a threshold injury.

Time Limits and Dispute Options

Claims must be made within a reasonable time after the accident, though the exact deadline is not specified in the Motor Accident Injuries Act 2017. However, benefits for injuries that do not meet the threshold injury criteria are generally limited to 52 weeks. If your claim is denied, you may request a review by the NSW Civil and Administrative Tribunal (NCAT) or seek legal advice.

When to Seek Legal Advice

The CTP scheme has complex rules, and eligibility for TBI claims depends on the specific circumstances of your injury. If your claim is denied or you are unsure about your entitlements, it is important to consult a legal professional. An experienced solicitor can help you understand your options and ensure your claim meets the legal requirements.
