How Traumatic Brain Injuries Are Assessed in NSW CTP Claims

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).

Traumatic brain injuries (TBIs) are among the most serious injuries covered under New South Wales' Compulsory Third Party (CTP) insurance scheme. Under the Motor Accident Injuries Act 2017, claims for TBIs are evaluated based on medical evidence, the nature of the injury, and the impact on the injured person's daily life. SIRA (State Insurance Regulatory Authority) provides detailed guidelines to assess compensation, distinguishing between 'threshold injuries' and more severe cases. This article explains how TBIs are assessed, what evidence is required, and practical steps for claimants.

Key Legal Framework for TBI Claims

The NSW CTP scheme covers injuries resulting from motor vehicle accidents, including TBIs. SIRA’s Motor Accident Guidelines outline how injuries are classified, with TBIs typically falling under the 'severe' or 'extreme' categories. Under the Motor Accident Injuries Act 2017, claims for TBIs may qualify for:

  • Weekly income payments if the injury prevents work for 52 weeks or more.
  • Lifelong or long-term benefits for injuries with permanent impairments.
  • Treatment and care benefits to cover medical expenses.

SIRA assesses the injury using the 'whole person impairment' approach, which considers physical, psychological, and functional impacts. For example, a TBI causing memory loss, speech difficulties, or depression may qualify for higher compensation than a 'threshold injury' (a minor injury with no lasting impairment).

Evidence Required for TBI Claims

To support a TBI claim, claimants must provide:

  • Medical records showing the injury’s cause, diagnosis, and treatment. This includes scans, specialist reports, and notes from neurologists or psychiatrists.
  • Accident details such as police reports, witness statements, and photographs of the scene.
  • Evidence of ongoing impact like school or work records, therapy notes, and statements from family or employers.
  • Income records to demonstrate lost earnings, especially if the injury prevents work.

SIRA may also request a medical expert’s opinion to assess the injury’s severity and long-term effects. For instance, a TBI causing permanent cognitive impairment would likely qualify for lifelong benefits, while a temporary concussion with full recovery might fall under the 52-week statutory limit.

Practical Example: TBI Claim Under NSW CTP

Consider a scenario: A 32-year-old motorcyclist suffers a TBI after a collision. Medical records show damage to the frontal lobe, leading to memory loss and difficulty concentrating. The injured person cannot return to their job as a software developer and requires ongoing therapy. Under SIRA’s guidelines, this would likely qualify for:

  • Lifelong weekly payments due to the injury’s permanence.
  • Treatment benefits to cover therapy and medication.

However, if the injury is later found to be a 'threshold injury' (e.g., no lasting cognitive effects), payments may be limited to 52 weeks. This distinction highlights the importance of accurate medical assessment.

Time Limits and Dispute Resolution

Claims must be submitted within a reasonable time frame, though the exact deadline is not specified in the Motor Accident Injuries Act 2017. Delays can jeopardize entitlements, especially for long-term injuries. If a claim is disputed, SIRA may request additional evidence or refer the case to a dispute resolution process. Claimants should seek legal advice if they disagree with an insurer’s assessment.

When to Seek Legal Advice

While SIRA provides a framework for claims, individual circumstances can vary. For example, a TBI resulting from a blameless accident (where no fault is attributable to the driver) may involve complex negotiations. Legal advice is recommended if:

  • The claimant is unsure whether their injury meets the 'severe' threshold.
  • The insurer disputes the injury’s severity.
  • The claimant needs assistance with documentation or dispute resolution.

Next Steps for Claimants

If you or a loved one has suffered a traumatic brain injury in a motor accident, start by:

  1. Seeking immediate medical attention to document the injury.
  2. Preserving evidence like accident reports, medical records, and witness statements.
  3. Contacting SIRA to understand your entitlements under the CTP scheme.

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

Traumatic brain injuries under NSW CTP claims are assessed based on medical evidence, injury severity, and long-term impact. SIRA’s guidelines help determine compensation, but claimants must provide detailed records to support their case. If you’re unsure about your options, seek legal advice to ensure your rights are protected.
