If you're involved in a NSW Compulsory Third Party (CTP) motor accident claim and facing a medical assessment dispute, knowing what evidence to retain is critical. Medical records, treatment documentation, and assessment reports play a central role in determining compensation. This guide explains which records are essential, how to preserve them, and what happens if evidence is lost. It also outlines the legal process for disputing medical assessments under NSW CTP laws.

The Legal Framework for Medical Assessments

Under the Motor Accident Injuries Act 2017 (MAIA), medical assessments are required to determine the nature and extent of injuries for CTP claims. The Personal Injury Commission (PIC) oversees these assessments, ensuring they align with the Motor Accident Guidelines. Key principles include:

  • Threshold injuries must meet specific neurological criteria, such as spinal nerve-root injuries producing clinical signs. Radiculopathy requires defined clinical evidence.
  • Soft tissue injuries are limited to 52 weeks of weekly benefits unless the injury results in whole person impairment (WPI) of 10% or more. This distinction affects long-term entitlements.
  • Medical assessments must be conducted by registered medical practitioners and follow SIRA’s guidelines. Disputes over these assessments are resolved through internal reviews or PIC mediation.

Essential Evidence to Retain During Disputes

When a medical assessment is challenged, retaining the following records is vital:

  • Original medical reports from doctors, physiotherapists, and specialists. These must include diagnosis dates, treatment plans, and progress notes.
  • Accident reports from police or SIRA. These establish the incident’s timeline and link injuries to the accident.
  • Witness statements and photographs of the accident scene. These can corroborate the injury’s cause.
  • Medical imaging (e.g., MRI, X-rays) and test results. These are key for proving soft tissue or spinal injuries.
  • Correspondence with insurers, including claims forms and medical assessment requests. This shows the claim’s history.
  • Income records and care records. These support claims for lost wages or additional care needs.

Losing any of these can weaken your case. For example, if a claimant discards a doctor’s note stating a spinal nerve-root injury, it may invalidate their right to ongoing weekly benefits.

How to Document Medical Assessments

To avoid disputes, claimants and insurers should:

  • Request copies of all medical records in writing. This ensures a paper trail.
  • Keep records of all communication with medical professionals, including appointment dates and treatment outcomes.
  • Document any changes in symptoms or treatment effectiveness. This shows the injury’s progression.
  • Store records securely in a safe location, such as a locked filing cabinet or online storage with encryption.

Insurers must also ensure their medical assessments are backed by evidence. If an insurer disputes a claimant’s injury severity, they must provide their own medical reports to support the challenge.

Legal Risks of Losing Evidence

Discarding or misplacing critical evidence can have serious consequences. Under the MAIA, claimants must prove their injuries are not ‘threshold injuries’ to qualify for long-term benefits. If medical records are lost, the PIC may:

  • Reject the claim due to insufficient evidence.
  • Limit benefits to the 52-week statutory cap, even if the injury is more severe.
  • Delay dispute resolution while the claimant retrieves missing records.

For insurers, failing to retain medical assessments can lead to penalties for non-compliance with SIRA guidelines. The PIC has strict rules about how long records must be kept, and missing this can result in legal action.

Internal Review Process for Medical Disputes

If a medical assessment is disputed, the PIC provides an internal review pathway. Claimants can request a review by:

  1. Submitting a written objection to the PIC within 28 days of the assessment.
  2. Providing new evidence that was not available at the time of the original assessment.
  3. Requesting a second medical opinion from an independent practitioner.

The PIC must respond to the review within 28 days. If the claimant is unsatisfied, they may escalate the matter to the NSW Civil and Administrative Tribunal (NCAT) for further review. However, it’s important to note that a challenge does not guarantee a changed decision. The PIC has discretion to uphold the original assessment if the evidence does not meet the legal threshold.

When to Seek Legal Advice

Medical assessment disputes can be complex. If you’re unsure whether your records are sufficient, or if an insurer is disputing your claim, it’s important to seek legal advice. A solicitor can:

  • Review your medical records to ensure they meet the legal standard.
  • Challenge an insurer’s refusal to accept your evidence.
  • Represent you in PIC reviews or NCAT proceedings.

Time limits also apply. For example, if a claimant loses key medical records after the 52-week period, they may lose their right to ongoing benefits. Acting quickly is essential to protect your entitlements.

Next Steps

Medical assessment disputes in NSW CTP claims hinge on retaining the right evidence. By understanding what records are essential and how to preserve them, you can avoid unnecessary delays or losses.
