Understanding Traumatic Brain Injury Claims under NSW CTP Law
A traumatic brain injury (TBI) resulting from a motor vehicle accident in New South Wales may give rise to entitlements under the Compulsory Third Party (CTP) insurance scheme. The Motor Accident Injuries Act 2017 and associated Motor Accident Injuries Regulation 2017 govern the process. To establish a claim, the injured person must demonstrate that the TBI arose from the accident, and that it has caused or is likely to cause a significant and permanent impact on their life. The assessment process is critical to determining eligibility for treatment and care benefits, weekly income payments, and, in some cases, damages for non-economic loss.
What the SIRA Guidelines Say About TBI Assessments
The State Insurance Regulatory Authority (SIRA) provides guidance on medical assessments for traumatic brain injuries. These assessments are conducted by independent medical practitioners approved under the CTP scheme. The purpose is to determine the nature, severity, and long-term impact of the TBI. SIRA requires that assessments consider the full medical history, including any pre-existing conditions, and assess functional impairments in areas such as cognition, memory, emotional regulation, and daily living activities. The assessment must be based on clinical evidence, not assumptions.
Practical Steps to Prepare for Your Medical Assessment
To prepare for a medical assessment in Ballina or elsewhere in NSW, claimants should:
- Gather and organise all medical records related to the TBI, including emergency department notes, neuroimaging reports (such as CT or MRI scans), specialist consultations, and rehabilitation progress notes.
- Maintain a daily journal documenting symptoms such as headaches, fatigue, mood changes, concentration difficulties, or sleep disturbances. This can help demonstrate the ongoing impact of the injury.
- Provide a written statement outlining how the TBI has affected daily life, including work, family responsibilities, and social participation. This should be factual and supported by evidence.
- Bring any relevant diagnostic test results, such as neuropsychological assessments, to the appointment. These are often required to assess cognitive and emotional function.
- Confirm the appointment details and bring identification and the CTP claim reference number.
SIRA emphasises that assessments are not routine check-ups. They are formal evaluations intended to assess whole person impairment (WPI) and functional capacity. Claimants should arrive on time, be honest about symptoms, and avoid exaggeration.
Evidence That Matters in TBI Claims
The following types of evidence are routinely considered in TBI claims under NSW CTP law:
- Medical reports from neurologists, psychiatrists, or neuropsychologists.
- Results from formal cognitive assessments, such as the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) or the Montreal Cognitive Assessment (MoCA).
- Documentation of treatment received, including medication, therapy, and rehabilitation.
- Employment records showing changes in performance, absence from work, or return to modified duties.
- Statements from family members, employers, or close friends about behavioural or functional changes.
The presence of a TBI does not automatically entitle a person to damages. The Motor Accident Injuries Act 2017 sets out that damages for non-economic loss (such as pain and suffering) are only available if the injury meets the threshold for a serious injury. For TBI, this means a permanent and significant impact on the person’s ability to carry out everyday activities, and a whole person impairment of at least 15%.
Time Limits and Dispute Options
There is a time limit to begin a claim under the CTP scheme. A claim must be made within three years of the accident date. However, for TBI claims, delays in diagnosis or the emergence of symptoms may affect when the claim period begins. It is important to notify the insurer as soon as possible after the accident, and to keep records of all communications.
If a claimant disagrees with a medical assessment outcome, they may request a review by an independent medical assessor or apply to the NSW Civil and Administrative Tribunal (NCAT) for a review of the decision. The process must be initiated within 28 days of receiving the assessment report. Disputes over the assessment of WPI or the impact of the TBI are common and may require legal advice to navigate.
Hypothetical Example: Preparing for a TBI Assessment in Ballina
A 38-year-old man in Ballina was involved in a rear-end collision in February 2025. He experienced a concussion at the time, but symptoms such as memory lapses, irritability, and difficulty concentrating did not become apparent until six months later. He sought medical assessment in August 2025 and was diagnosed with a mild traumatic brain injury. His treating neurologist referred him for a formal assessment under the CTP scheme. To prepare, he collected all emergency department notes, MRI reports, and a diary of daily symptoms. He also obtained a neuropsychological assessment and a statement from his employer confirming reduced productivity. This documentation was submitted to SIRA prior to his assessment in October 2025.
