What Evidence to Keep for Lumbar Disc Herniation Claims in NSW CTP (Illawarra & South Coast)

This article explains which evidence is essential for lumbar disc herniation claims under NSW CTP laws, including medical records, accident reports, and SIRA requirements. It outlines practical steps to preserve evidence, time limits, and when to seek legal advice.

Current as at 22 August 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 from a motor accident in NSW, retaining specific evidence is crucial to support your CTP claim. This article explains which medical records, documentation, and evidence are essential to prove your injury and claim compensation under NSW law. The focus is on the Illawarra and South Coast regions, where claimants must meet the requirements set by SIRA (State Insurance Regulatory Authority) for CTP claims.

What Evidence Matters for Lumbar Disc Herniation Claims

To support a CTP claim for a lumbar disc herniation, you must provide evidence that directly links your injury to the accident. Key records include:

  • Medical imaging (e.g., MRI or CT scans) showing the herniation and its location.
  • Doctor's notes detailing the diagnosis, treatment plan, and how the injury affects your mobility or daily activities.
  • Physiotherapy or specialist records showing the type and duration of treatment required.
  • Accident reports from police or witnesses, including details of how the collision occurred.
  • Witness statements from people who saw the accident or can confirm your injuries.
  • Medical bills and receipts for treatment related to the herniation.

SIRA requires evidence that your injury meets the 'threshold injury' definition under the Motor Accident Injuries Act 2017. For example, a herniated disc causing neurological symptoms like numbness or weakness must be documented by a medical practitioner.

Practical Steps to Preserve Evidence

After a lumbar disc herniation, take these steps to protect your claim:

  1. Seek immediate medical attention to document the injury. Delaying treatment may weaken your case.
  2. Keep all medical records in a secure location. This includes GP notes, specialist reports, and imaging results.
  3. Report the accident to the police and obtain a copy of the incident report.
  4. Notify your insurer as soon as possible. Delays in reporting may affect your entitlement to benefits.
  5. Record your symptoms and how the injury impacts your ability to work or perform daily tasks.

If you're unsure whether your injury qualifies as a 'threshold injury', consult a medical practitioner who can provide a formal assessment. SIRA's guidelines define threshold injuries as those requiring treatment and causing a significant impact on your life.

Time Limits and Dispute Resolution

CTP claims must be made within a specific timeframe. Under NSW law, you must notify the at-fault driver's insurer within 52 weeks of the accident. If you fail to report within this period, you may lose your right to claim benefits.

If your claim is disputed, SIRA provides a formal review process. You can request a review of your claim's assessment by submitting a written objection within 28 days of receiving the decision. During this process, you may need to provide additional evidence to support your case.

When to Seek Legal Advice

While SIRA provides a framework for CTP claims, the process can be complex. For example, if your injury involves a 'whole person impairment' rating or if you're seeking compensation for lost income, you may need legal assistance. A solicitor can help you understand whether your claim meets the criteria for benefits or damages under the Motor Accident Injuries Act 2017.

Example Scenario

Consider a claimant who suffered a lumbar disc herniation after a collision on the Princes Highway near Wollongong. Their MRI scan showed a herniated disc at L4-L5, and their doctor noted numbness in the left leg. The claimant kept records of all medical appointments, treatment costs, and a police report. This evidence helped support their claim for weekly income benefits and treatment expenses under the CTP scheme.
