Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

If you're involved in a NSW Compulsory Third Party (CTP) motor accident claim and facing a dispute over your medical assessment, understanding what evidence to retain is critical. Medical disputes often hinge on documentation of injuries, treatment records, and expert opinions. In the Blue Mountains and Nepean regions, claimants must ensure all evidence aligns with SIRA’s evaluation standards. This guide explains the key records to preserve, how SIRA assesses disputes, and steps to take if your claim is challenged.

NSW CTP Rules Behind Medical Disputes

Under the Motor Accident Injuries Act 2017, SIRA oversees claims for injuries caused by motor vehicle accidents. When a dispute arises over a medical assessment, SIRA evaluates whether the injury meets the threshold for compensation. This includes assessing whether the injury is a 'threshold injury', a soft tissue injury with neurological signs, such as a spinal nerve-root injury. If the injury falls below this threshold, benefits may be limited or denied. Claimants must provide evidence that their injury meets these criteria, including medical reports, imaging, and expert opinions.

Evidence and Records to Retain

To support your CTP claim during a medical assessment dispute, retain the following:

  • Medical records: Ensure all reports from doctors, physiotherapists, and specialists are complete. Highlight how each treatment relates to the accident.
  • Accident details: Keep police reports, witness statements, and photographs of the scene. These help establish the injury’s connection to the accident.
  • Income and employment records: Provide evidence of lost wages or reduced earning capacity, as SIRA considers this when assessing long-term impacts.
  • Insurer correspondence: Document all communication with the at-fault driver’s insurer, including dates and responses.
  • Expert opinions: If a medical expert has assessed your injury, retain their report and any correspondence with SIRA.

SIRA’s Role in Medical Disputes

SIRA evaluates medical disputes by reviewing all evidence and determining whether the injury meets the threshold for compensation. If a claimant disputes SIRA’s decision, they can request an internal review or escalate to the Personal Injury Commission (PIC). SIRA’s guidelines state that claimants must provide 'clear and convincing evidence' to challenge a decision. This includes medical records that demonstrate the injury’s severity and how it impacts daily life.

Time Limits and When to Seek Advice

CTP claims must be submitted within 52 weeks of the accident, unless an extension applies. If a dispute arises after this period, benefits may be restricted. For example, if your injury is classified as a threshold injury, benefits are generally limited to 52 weeks. If you believe your claim is being unfairly assessed, seek legal advice immediately. Delays can jeopardize your ability to challenge a decision.

Example: A Claimant’s Dilemma

Consider a claimant in the Blue Mountains who suffered a soft tissue injury after a car accident. Their doctor documented neurological signs, but SIRA disputed the injury’s severity. The claimant retained all medical records, including imaging and a detailed report from a specialist, which helped clarify the injury’s impact. This evidence was critical in challenging SIRA’s initial assessment.

Next Steps

If your CTP claim is being disputed over medical evidence, act quickly. Ensure all records are complete and submit them to SIRA within the 52-week timeframe. If you need assistance navigating the process, complete the quick, no obligation enquiry form to request contact about your circumstances.
