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, preparing for medical assessments is critical to securing compensation under the Compulsory Third Party (CTP) scheme. This article explains how the NSW CTP system evaluates TBI claims, what evidence matters, and practical steps to take in Western Sydney.

How SIRA Evaluates TBI Claims

The State Insurance Regulatory Authority (SIRA) administers the NSW CTP scheme, which provides statutory benefits for injuries resulting from motor vehicle accidents. For traumatic brain injuries, SIRA assesses claims based on the Motor Accident Injuries Act 2017 and the Motor Accident Guidelines. Key factors include:

  • Whether the injury meets the 'threshold injury' definition (injuries requiring medical treatment, including neurological signs like memory loss or speech difficulties)
  • The type of medical evidence required to support your claim
  • Whether your injury qualifies for weekly income payments or treatment benefits

SIRA distinguishes between 'threshold injuries' and 'whole person impairment' (WPI) claims. While TBI claims are typically limited to threshold injuries under the CTP scheme, some cases may involve common law damages if the injury meets specific WPI criteria. However, the CTP scheme does not cover common law claims.

Practical Steps to Prepare for Medical Assessments

To support your TBI claim, you must provide clear evidence of your injury and its impact. Here are essential steps:

1. Obtain Comprehensive Medical Records

  • Ensure your treating medical practitioners (neurologists, psychiatrists, or general practitioners) document:
  • Neurological symptoms (e.g., memory loss, speech difficulties, coordination issues)
  • Diagnostic imaging (MRI/CT scans) showing brain injury
  • Cognitive assessments (e.g., memory tests, attention tests)
  • Request written reports detailing your injury's severity and expected recovery timeline

2. Preserve Accident Evidence

  • Gather details of the accident, including:
  • Police reports
  • Witness statements
  • Photographs of the scene and vehicle damage
  • Video footage (if available)
  • Note any immediate symptoms experienced after the accident

3. Understand the Medical Assessment Process

SIRA may require you to undergo independent medical assessments to verify your injury. These assessments typically focus on:

  • Confirming the injury meets the threshold injury definition
  • Assessing the extent of your functional impairment
  • Determining whether your injury qualifies for weekly benefits

Prepare by:

  • Arranging appointments with specialists familiar with TBI assessments
  • Bringing all relevant medical records to each assessment
  • Being honest about your symptoms and daily challenges

4. Document Your Daily Life Impact

Keep a journal or diary to record:

  • Changes in your ability to work or perform daily tasks
  • Use of assistive devices (e.g., memory aids, mobility equipment)
  • Financial impact of your injury (e.g., lost income, out-of-pocket medical costs)

Time Limits and Dispute Resolution

The CTP scheme has strict time limits for claims. For example:

  • Weekly income benefits are generally limited to 52 weeks if your injury is limited to threshold injuries (s 4.4 of the Motor Accident Injuries Act 2017)
  • You must notify your insurer of your claim within 52 weeks of the accident (s 3.28)

If your claim is disputed, you may:

  • Request a review by SIRA
  • Seek mediation through the NSW Civil and Administrative Tribunal (NCAT)
  • Consult a solicitor to explore legal options

Example Scenario

Consider a person who suffered a TBI in a car accident in Western Sydney. Their medical team documented memory loss, speech difficulties, and coordination issues. They preserved police reports and witness statements. During an independent assessment, the specialist confirmed the injury met the threshold injury definition. This evidence supported the claim for weekly benefits and treatment costs.

When to Seek Legal Advice

While this article provides general guidance, your circumstances may require tailored advice. A solicitor can:

  • Help you understand your entitlements under the CTP scheme
  • Assist with dispute resolution processes
  • Advise on whether your claim may involve common law damages

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.

Next Steps

If you're preparing for a medical assessment or have questions about your TBI claim, take these actions:

  1. Gather all medical records and accident evidence
  2. Schedule appointments with specialists familiar with CTP assessments
  3. Notify your insurer within 52 weeks of the accident
  4. Seek legal advice if your claim is disputed or you're unsure about your options

By understanding the CTP scheme's requirements and preparing thoroughly, you can better support your claim for compensation.
