Dispute Resolution Options for Traumatic Brain Injury CTP Claims in NSW

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 accident and are disputing your CTP claim in New South Wales, understanding your options is critical. The NSW CTP scheme, governed by the Motor Accident Injuries Act 2017 (MAIA), provides specific pathways to resolve disagreements with insurers. This article explains the formal dispute resolution processes, the role of SIRA, and practical steps to challenge a claim.

Key Dispute Resolution Mechanisms

  1. Internal Review by the Insurer

Under the MAIA, insurers must provide an internal review of claim decisions. If you dispute the assessment of your TBI-related injuries, you can request a review within 28 days of receiving the decision. This process allows the insurer to reassess medical evidence, claim forms, and injury documentation.

  1. SIRA’s Role in Dispute Resolution

SIRA (State Insurance Regulatory Authority) oversees the CTP claims process and provides guidance on assessing injuries. For disputes over the severity or classification of a TBI, SIRA’s guidelines on neurological impairments and functional limitations are central. Claimants can request a written explanation of how their injury meets the threshold for compensation under the MAIA.

  1. Personal Injury Commission (PIC) Medical Dispute Pathway

If the insurer refuses to reconsider a claim, you may escalate the dispute to the PIC. This body reviews medical evidence and can order an independent assessment of your TBI. The PIC’s decision is binding, but it does not guarantee a change in the insurer’s initial assessment.

  1. Legal Action as a Last Resort

If all other options fail, claimants may pursue legal action through the NSW Civil and Administrative Tribunal (NCAT) or the Supreme Court. This requires legal representation and is typically reserved for complex cases involving disputed medical evidence or alleged underpayment of benefits.

Practical Steps for Resolving TBI Claims

To build a strong case, gather the following evidence:

  • Medical records detailing the TBI, including scans, specialist reports, and rehabilitation notes.
  • Accident report from the police or insurer, confirming the incident and any pre-existing conditions.
  • Witness statements or CCTV footage supporting the claim.
  • Income and employment records to demonstrate lost earnings or care costs.

When disputing a claim, clearly identify the specific issue, for example, whether the insurer correctly classified the TBI as a threshold injury under the MAIA. SIRA’s guidelines on neurological impairments (e.g., cognitive function, memory loss, or speech difficulties) are essential to reference.

Time Limits and When to Seek Advice

The MAIA imposes strict deadlines. For example, you must notify the insurer of your claim within 90 days of the accident. If you dispute a decision, you have 28 days to request an internal review. Missing these timelines can jeopardize your ability to challenge the claim. Seek legal advice promptly if the insurer denies benefits or disputes the severity of your injury.

Example Scenario

Consider a claimant who suffered a concussion after a car accident. The insurer initially denied the claim, arguing it was a minor injury. The claimant requested an internal review, citing SIRA’s guidelines on post-concussion symptoms like memory loss and attention deficits. After the insurer rejected the review, the claimant escalated the dispute to the PIC, which ordered an independent neurological assessment. The PIC’s decision confirmed the injury met the threshold for compensation.

Next Steps

Disputing a TBI CTP claim requires careful navigation of the MAIA and SIRA’s processes. If you’re unsure how to proceed, seek guidance from a solicitor specialising in NSW CTP claims.
