Common Mistakes in Medical Assessments for NSW CTP Claims

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).

Medical assessments are a critical part of NSW Compulsory Third Party (CTP) claims. However, injured road users in the Blue Mountains and Nepean regions often make errors that can delay or reduce their compensation. One common mistake is failing to follow the medical guidelines set by the State Insurance Regulatory Authority (SIRA). For example, not documenting symptoms accurately or not seeking a second opinion when a medical report contradicts the claimant’s experience can lead to disputes.

Another frequent error is not understanding the distinction between statutory benefits and common law damages. Statutory benefits, such as weekly income payments, are limited to 52 weeks for threshold injuries under the Motor Accident Injuries Act 2017. If a claimant believes their injury exceeds this threshold, they must provide evidence like MRI scans or specialist reports to challenge the assessment.

How SIRA Handles Medical Evidence Disputes

SIRA evaluates medical assessments based on the Motor Accident Guidelines, which define threshold injuries. If a dispute arises, claimants should request a review through the Personal Injury Commission (PIC). SIRA’s process involves a medical expert reviewing the evidence, but a challenge does not guarantee a changed decision. For instance, if a doctor’s report fails to note neurological signs required for a soft-tissue injury, the claimant may need to seek an independent assessment.

In the Blue Mountains and Nepean, claimants should note that SIRA’s regional offices may have different processing times. Delays in submitting evidence or failing to meet deadlines for disputes can jeopardize benefits. Always keep copies of all medical records, accident reports, and correspondence with insurers.

Steps to Avoid Medical Assessment Disputes

To protect your claim, injured road users should:

  • Follow medical guidelines: Adhere to SIRA’s requirements for documenting injuries and treatment.
  • Seek specialist input: If a medical report is unclear, consult a specialist familiar with CTP claims.
  • Act quickly: Disputes over medical assessments must be resolved within 52 weeks for threshold injuries. After this period, benefits are generally limited unless the injury is classified as a whole-person impairment.
  • Review evidence: Ensure all medical records clearly link the injury to the accident, including pre-existing conditions.

A hypothetical example: A cyclist in the Blue Mountains sustains a soft-tissue injury but is told their claim is limited to 52 weeks. They later discover the medical report did not note spinal nerve-root signs required for a threshold injury. By seeking a second opinion and submitting updated records, they successfully challenge the assessment.

When to Seek Legal Advice

Medical disputes can be complex, especially when involving long-term impairments or disputes over weekly benefits. If you face a disagreement with SIRA or an insurer, contact a solicitor specialising in NSW CTP claims. Legal advice can help you navigate the review process and ensure your evidence meets the required standards.
