How to Resolve Medical Assessment Disputes in NSW CTP Claims

If you disagree with a medical assessment in your NSW Compulsory Third Party (CTP) claim, understanding your options is critical. Medical assessments determine your eligibility for benefits like weekly payments, treatment costs, and long-term care. Disputes often arise when the assessment doesn't reflect the full extent of your injuries or when there are inconsistencies in the report. This article explains how to challenge such assessments under NSW law, including SIRA’s role, internal review processes, and alternative dispute resolution options.

The Legal Framework Behind Medical Assessments

NSW CTP claims are governed by the Motor Accident Injuries Act 2017 and the Motor Accident Injuries Regulation 2017. The Personal Injury Commission (PIC) oversees medical assessments for claims involving injuries above the 'threshold' level. Threshold injuries are defined as those requiring medical treatment, such as soft tissue injuries, spinal nerve-root damage, or fractures. Under the scheme, SIRA (State Insurance Regulatory Authority) manages claims and must ensure assessments are 'reasonable and necessary' based on medical evidence.

Medical assessments are conducted by approved medical practitioners, and their reports are central to determining benefits. If you believe the assessment is incorrect, you can request a review through SIRA’s internal process. However, the PIC has the final authority to decide whether the assessment meets the legal standard for benefits.

Practical Steps and Evidence to Gather

To challenge a medical assessment, you must first understand what evidence matters. Key documents include:

  • Medical records: Ensure your treating doctor’s notes clearly document your injuries, treatment, and recovery progress.
  • Accident reports: Police reports or witness statements can support claims of pre-existing conditions or aggravation of injuries.
  • Insurer correspondence: Keep copies of all communication with SIRA or the at-fault driver’s insurer.
  • Second opinions: A new medical report from an independent practitioner may be required to dispute the original assessment.

If the assessment was based on incomplete information, such as a lack of follow-up care, you may need to provide evidence of ongoing treatment. For example, if you were not referred for physiotherapy after a soft tissue injury, this could affect the assessment’s accuracy.

Time Limits and When to Seek Advice

NSW CTP claims have strict time limits. You must notify SIRA of your intention to dispute the assessment within 52 weeks of the accident. If the dispute relates to threshold injuries, benefits are generally limited to 52 weeks under the scheme. However, if the injury is above threshold, you may be eligible for long-term payments.

If you’re unsure whether your injury meets the threshold, seek advice before the 52-week deadline. SIRA’s internal review process allows for reconsideration of medical reports, but the PIC has the final say. Delays can result in lost benefits, so acting promptly is essential.

Dispute Resolution Options

1. SIRA’s Internal Review Process

If you disagree with a medical assessment, you can request a review by SIRA. This involves:

  • Submitting a written objection to the assessment.
  • Providing additional evidence, such as a second medical opinion.
  • Waiting for SIRA to reassess the report and issue a revised decision.

SIRA must respond within 28 days of receiving your objection. If the review concludes the assessment was incorrect, benefits may be adjusted. However, SIRA’s decision is not binding unless the PIC confirms it.

2. PIC Medical Dispute Pathway

For claims involving injuries above threshold, disputes can be escalated to the PIC. The PIC’s role is to determine whether the medical assessment meets the legal standard for benefits. This process includes:

  • A medical expert’s report confirming the injury’s severity.
  • A hearing where both parties can present evidence.
  • A final determination by the PIC.

The PIC’s decision is final and cannot be appealed. However, you can request a review of the PIC’s decision if new evidence emerges.

3. Alternative Dispute Resolution

In some cases, mediation may be an option. SIRA offers mediation services to resolve disputes without formal legal proceedings. This is particularly useful for claims involving complex medical evidence or disagreements over treatment costs.

A Hypothetical Example

Imagine a car accident where you suffered a soft tissue injury. SIRA’s initial assessment concludes it’s a threshold injury, limiting your benefits to 52 weeks. However, your doctor later reports ongoing pain and limited mobility, suggesting a more severe injury. You can request a second medical opinion and submit it to SIRA. If SIRA agrees the injury is above threshold, your benefits may be adjusted accordingly.

Next Steps

Medical assessment disputes require careful handling. If you’re unsure whether your claim meets the threshold or if the assessment is incorrect, seek legal advice before the 52-week deadline. While SIRA and the PIC have the authority to make final decisions, you have the right to challenge their assessments with the right evidence. Every claim depends on its own facts.
