If you're involved in a NSW Compulsory Third Party (CTP) motor accident claim and facing a medical assessment dispute, preserving the right evidence is critical. This article explains what medical records to keep, how SIRA guidelines shape evidentiary standards, and the practical steps to avoid delays. It also covers the process for disputing medical assessments under NSW law.

Essential Medical Records for CTP Disputes

When disputing a medical assessment in a CTP claim, you must retain records that directly relate to your injury, treatment, and recovery. Key documents include:

  • Medical reports from doctors, physiotherapists, and specialists involved in your care
  • Diagnostic imaging (e.g., X-rays, MRIs) showing injury details
  • Progress notes documenting treatment plans and recovery milestones
  • Clinical records outlining the severity of your condition and any neurological signs
  • Expert opinions from medical practitioners confirming the injury's impact

SIRA guidelines require evidence to demonstrate a 'threshold injury' or 'whole person impairment' for benefits. For example, if your claim hinges on a soft-tissue injury, records must show spinal nerve-root damage with neurological signs, not just radiculopathy.

SIRA Guidelines and Evidentiary Standards

SIRA's Motor Accident Guidelines define what constitutes a threshold injury under the Motor Accident Injuries Act 2017. For disputes, you must prove:

  • The injury meets the definition of a 'threshold injury' (e.g., soft tissue, fracture, or neurological damage)
  • The injury resulted directly from the accident
  • The injury's impact on your daily life and capacity

Medical records must clearly link your symptoms to the accident. For instance, if a doctor disputes the injury's severity, you must provide records showing a consistent progression of symptoms from the accident date. SIRA also requires evidence of 'ordinary use' of the vehicle, which may affect claims involving private property or car parks.

Practical Steps for Record-Keeping

To avoid claim delays, take these steps:

  1. Organise all medical records in chronological order, starting from the accident date
  2. Request copies of all reports, as originals may be lost or damaged
  3. Document treatment timelines to show continuity of care
  4. Keep correspondence with insurers, medical providers, and SIRA
  5. Photograph injuries and document daily impacts (e.g., mobility issues)

If a medical assessment is disputed, ensure records show how the injury affects your ability to work, perform daily tasks, or engage in activities. For example, if you're claiming weekly income payments, records must prove your injury prevents you from working for 52 weeks or more.

Disputing Medical Assessments

If a medical assessment is challenged, the Personal Injury Commission (PIC) may request an internal review. This process requires:

  • Submitting new evidence that contradicts the original assessment
  • Providing expert medical opinions supporting your case
  • Demonstrating that the original assessment failed to consider key evidence

Note that a challenge does not guarantee a changed decision. The PIC will assess whether the new evidence meets the legal threshold for benefits. For example, if the original assessment correctly identified a 'threshold injury' but underestimated its impact, you may need additional evidence to justify higher weekly payments.

Time Limits and Next Steps

CTP claims must be submitted within 52 weeks of the accident, though extensions may apply for serious injuries. If a medical assessment dispute arises after this period, you may lose eligibility for certain benefits. Seek legal advice immediately if:

  • You receive a medical assessment that denies your claim
  • You believe the assessment ignores key evidence
  • You need to challenge a decision under the PIC's review process

Armidale-based claimants should contact a solicitor familiar with SIRA's evidentiary requirements. Properly preserved records can make the difference between a successful claim and a denied assessment.
