Lumbar Disc Herniation, Dispute Resolution Options in NSW CTP Claims

This article explains dispute resolution options for lumbar disc herniation injuries under NSW CTP laws. It outlines how SIRA assesses such claims, the steps to challenge a decision, and the role of the Personal Injury Commission. Practical evidence requirements and time limits are also covered.

Current as at 6 November 2026

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've suffered a lumbar disc herniation injury in a motor accident in New South Wales, you may face disputes over your CTP claim. This article explains how to resolve such disputes under the Motor Accident Injuries Act 2017 (MAIA), including SIRA's role in assessing claims for lower back injuries. Practical steps, evidence requirements and options for challenging a decision are outlined below.

How SIRA Handles Lumbar Disc Herniation Claims

SIRA evaluates lumbar disc herniation injuries under the MAIA's threshold injury framework. A spinal nerve-root injury producing neurological signs (even without radiculopathy) may qualify as a soft-tissue injury. However, disputes often arise when claimants believe their injury meets the 'threshold injury' definition under the Motor Accident Guidelines. SIRA's internal review process allows claimants to challenge decisions, but outcomes depend on medical evidence and the injury's alignment with the guidelines.

Practical Steps for Lumbar Disc Herniation Claims

To resolve disputes, claimants should:

  • Gather medical records confirming the lumbar disc herniation and its impact
  • Obtain a detailed report from a specialist assessing the injury's severity
  • Submit a written request for internal review within 28 days of the decision
  • Consider a medical dispute resolution pathway if the claim is denied

Evidence such as MRI scans, physiotherapy records and a doctor's opinion on the injury's effect on daily activities are critical. SIRA may request additional assessments if the injury's nature or treatment is unclear.

Dispute Resolution Options

  1. Internal Review: SIRA allows a claimant to request a review of a decision within 28 days. This process involves a reassessment of the injury's classification and the claim's validity.
  2. Personal Injury Commission (PIC) Medical Dispute Pathway: If the claim is denied, claimants can apply to the PIC for a medical dispute resolution. This involves an independent medical expert reviewing the injury's classification and the claim's merits.
  3. Legal Action: In rare cases, claimants may pursue legal action through the NSW Civil and Administrative Tribunal (NCAT) or the District Court. This requires a solicitor to demonstrate that SIRA's decision was legally flawed.

Time Limits and Key Considerations

Disputes must typically be resolved within 28 days of the initial decision. If the claimant disagrees with the outcome of an internal review, they have 28 days to request a further review. Delays beyond this period may jeopardize the claim. It's important to note that SIRA's decisions are final unless there's a legal challenge, which is a complex process requiring specialist legal advice.

Hypothetical Example

Consider a claimant who suffered a lumbar disc herniation after a car accident. SIRA initially denied the claim, stating the injury did not meet the threshold injury definition. The claimant then requested an internal review, providing additional MRI evidence and a specialist report confirming the injury's severity. SIRA revised its decision, approving the claim. This example illustrates how evidence and the internal review process can resolve disputes.

When to Seek Legal Advice

Disputes over lumbar disc herniation claims can be complex. A solicitor can help assess whether the injury meets the threshold injury criteria, challenge SIRA's interpretation of the guidelines, or explore legal options if the claim is denied. Legal advice is particularly valuable when the injury's impact on daily life is disputed or when the claimant believes SIRA's decision was incorrect.

Next Steps

CTP claims involving lumbar disc herniation depend on the injury's classification, the evidence provided and the timing of disputes. If you're facing a dispute over your claim, it's important to act promptly. Every claim depends on its own facts.
