How SIRA Resolves Medical Assessment Disputes in 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).

If you're involved in a motor accident in NSW and disagree with a medical assessment, SIRA (State Insurance Regulatory Authority) provides clear rules to resolve disputes. This article explains how SIRA applies its guidelines to medical assessment conflicts, with a focus on Western Sydney.

Key SIRA Rules for Medical Disputes

SIRA outlines specific processes for resolving disputes over treatment plans, impairment assessments, and benefit eligibility. Under the Motor Accident Injuries Act 2017, claimants and insurers must follow a structured pathway to address disagreements. For example:

  • Medical reports must align with the Motor Accident Guidelines (e.g., threshold injury criteria, whole person impairment assessments). Discrepancies may require independent review.
  • Disputes over treatment plans must be resolved through SIRA’s internal review process, which considers clinical evidence and expert opinions.
  • Insurers must provide written reasons for rejecting claims based on medical assessments, ensuring transparency.

In Western Sydney, SIRA applies these rules consistently, though local healthcare providers may influence the availability of specific specialists for assessments.

Practical Steps for Resolving Disputes

When a medical assessment dispute arises, claimants and insurers should:

  1. Request a detailed explanation from the insurer about why a medical report was rejected.
  2. Submit additional evidence, such as second opinions or updated medical records, to support the claim.
  3. Seek independent medical review through SIRA’s process, which may involve a third-party expert.
  4. Monitor time limits, claims must typically be resolved within 52 weeks for threshold injuries, after which benefits may be restricted.

For example, if a claimant’s injury is classified as a threshold injury but the insurer disputes the severity, SIRA will assess whether the clinical signs meet the Motor Accident Guidelines. This ensures consistency across NSW, including Western Sydney.

Time Limits and When to Seek Advice

NSW CTP claims have strict deadlines. For instance:

  • Medical assessments must be completed within 52 weeks of the accident if the injury is a threshold injury. After this period, benefits like weekly payments may be limited.
  • Disputes must be resolved through SIRA’s internal review before escalating to the Personal Injury Commission (PIC). Delays can jeopardize entitlements.

If you’re unsure how to proceed, seek advice early. SIRA’s guidelines are complex, and missteps can affect your claim. Independent legal or medical guidance may be necessary to challenge a decision.

Final Steps

Medical assessment disputes in NSW CTP claims require adherence to SIRA’s structured process. While Western Sydney follows the same rules as other regions, local healthcare access may impact the availability of specialists. Always ensure your claim aligns with the Motor Accident Guidelines and seek assistance if disputes persist.
