What You Need to Know About TBI Claims Under NSW CTP Law

If you've suffered a traumatic brain injury (TBI) in a motor accident in NSW, you may be eligible for compensation through the Compulsory Third Party (CTP) insurance scheme. The Motor Accident Injuries Act 2017 (MAIA) governs all CTP claims, including those involving TBIs. You may claim treatment and care benefits, weekly income payments, and in some cases, damages for pain and suffering if your injury meets the legal threshold. This guide explains the process, what you can claim, and how to navigate the system.

Types of Support Available for TBI Claims

Under the MAIA, you may claim:

  • Treatment and care benefits to cover medical treatment, rehabilitation, and allied health services like neuropsychological assessments, speech therapy, and occupational therapy.
  • Weekly income payments if your TBI prevents you from working, calculated based on your pre-accident earnings.
  • Damages for non-economic loss (e.g., pain and suffering) and economic loss (e.g., future earnings) if your injury meets the threshold for a serious injury.

Damages are only available if your TBI results in a permanent impairment of at least 15% of the whole person, as assessed under the Motor Accident Guidelines. If your only injuries are classified as threshold injuries (including some TBIs), weekly benefits and treatment care benefits generally stop after 52 weeks from the accident date.

What Qualifies as a Threshold Injury for TBI Claims

A TBI may qualify as a threshold injury if it causes lasting cognitive, emotional, or physical impairments, such as memory loss, difficulty concentrating, personality changes, or ongoing headaches. Under the MAIA, a spinal nerve-root injury producing neurological signs other than radiculopathy may still fall within the soft tissue definition (s 1.6). Radiculopathy requires specific clinical signs under the Motor Accident Guidelines.

If your TBI results in a permanent impairment of 15% or more, you may be eligible to claim damages. However, if your injury is classified as a threshold injury (not meeting the 15% threshold), you may not be entitled to damages, but you may still receive weekly benefits and treatment care benefits for up to 52 weeks.

Evidence to Support Your TBI Claim

Strong medical evidence is essential to support your claim. This includes:

  • Detailed records of your initial assessment, including imaging like CT scans or MRIs.
  • Ongoing treatment records from a neurologist or neuropsychologist.
  • A diary documenting symptoms such as fatigue, dizziness, mood changes, or difficulty with daily tasks.
  • Photographs of the accident scene, witness statements, and a copy of the police report (if applicable).

Medical professionals must confirm that your symptoms are directly related to the accident and that your injury meets the threshold for a serious injury.

Time Limits and Next Steps

You must notify your insurer of your claim within 6 months of the accident or within 6 months of becoming aware of a connection between the accident and your injury, whichever is later. This is a strict deadline under the MAIA. Seek medical treatment as soon as possible after the accident, as delays may affect the assessment of your injury.

If you're dissatisfied with a decision, you may request a review from the insurer or apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination.

Common Questions About TBI Claims

  1. Is a TBI automatically considered serious? No. Your injury must meet the threshold for a serious injury as defined in the MAIA, which requires a permanent impairment of at least 15%.
  2. Can I claim damages if I was not at fault? Yes, as long as your injury meets the threshold and the accident was caused by another vehicle.
  3. Will CTP cover long-term care? Yes, if your TBI results in a permanent impairment, treatment and care benefits may continue beyond the initial 52-week period, depending on your ongoing needs and a formal assessment.

When to Seek Legal Advice

A TBI can have complex and long-term effects. Because the legal framework for CTP claims is strict and evidence-based, it's advisable to seek legal advice early. A solicitor can help you understand your rights, ensure your claim is properly documented, and assist with disputes regarding benefits or damages.

Hypothetical Example: A TBI Claim in Sydney

A 38-year-old office worker in Sydney was a passenger in a car struck from behind at a traffic light. She experienced a concussion and developed persistent headaches, difficulty concentrating, and mood swings. Over 12 months, she underwent neuropsychological testing, which showed a 20% whole person impairment due to her TBI. Her treating neurologist confirmed the symptoms were directly related to the accident. Because her injury met the threshold, she was able to claim damages for non-economic loss and future economic loss. Her claim was supported by medical records, a police report, and a detailed diary of her symptoms.
