Lumbar Disc Herniation and Changes to NSW CTP Claims After 2017 Reforms

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 in a motor vehicle accident in Greater Sydney, the 2017 reforms to New South Wales' Compulsory Third Party (CTP) laws may have a significant impact on your claim. The reforms introduced changes to how claims are assessed, the types of injuries covered, and the process for determining compensation. Understanding these changes is essential for anyone seeking compensation under the Motor Accident Injuries Act 2017 (MAIA).

What Changed with the 2017 Reforms?

Before 2017, the Motor Accidents Compensation Act 1999 (MACA) governed CTP claims. The 2017 reforms replaced MACA with the MAIA, which introduced a more structured approach to assessing claims. One of the key changes was the introduction of the 'threshold injury' concept. Under the MAIA, a claimant must have a threshold injury to be eligible for compensation. A lumbar disc herniation may qualify as a threshold injury if it meets the specific clinical criteria outlined in the Motor Accident Guidelines.

The reforms also introduced a distinction between 'threshold injuries' and 'non-threshold injuries'. Threshold injuries are defined as those that result in a whole person impairment of 10% or more, or that require treatment such as surgery. Lumbar disc herniation may fall under this category if it results in neurological signs or symptoms that meet the clinical criteria.

Practical Steps and Evidence That Usually Matter

If you have a lumbar disc herniation from a motor vehicle accident, the following evidence may be important to support your claim:

  • Medical records that detail the nature of the injury, including imaging reports such as MRI scans.
  • A diagnosis from a medical practitioner that confirms the injury meets the threshold injury criteria.
  • Evidence of the accident, such as a police report, witness statements, or photographs.
  • Any correspondence with the insurer that outlines the claim process.

It is important to seek medical attention promptly after an accident to ensure that the injury is documented and that the claim can be made within the required time limits.

Time Limits, Disputes and When to Seek Advice

Under the MAIA, there are strict time limits for making a CTP claim. Generally, a claim must be made within 52 weeks of the accident. If the injury is a threshold injury, the claimant may be eligible for weekly benefits and treatment and care benefits for up to 52 weeks. After that, the benefits may be limited unless the injury results in a whole person impairment of 10% or more.

If your claim is disputed, you may need to seek independent medical opinions or have the matter reviewed by a tribunal. It is important to understand that the assessment of a lumbar disc herniation as a threshold injury can be complex and may require specialist input.

A Realistic Example

Consider a scenario where a driver involved in a car accident in Greater Sydney suffers a lumbar disc herniation. The driver seeks medical attention and is diagnosed with a herniated disc that results in neurological signs such as numbness and tingling in the legs. The medical records confirm that the injury meets the threshold injury criteria. Under the MAIA, the driver may be eligible for weekly benefits and treatment and care benefits for up to 52 weeks. If the injury results in a whole person impairment of 10% or more, the claimant may be eligible for additional compensation.

When to Seek Legal Advice

If you are unsure whether your lumbar disc herniation qualifies as a threshold injury, or if your claim has been disputed, it is advisable to seek legal advice. A legal professional can help you understand your rights under the MAIA and ensure that your claim is processed correctly.

Next Steps

The availability of compensation under the MAIA depends on the specific facts of your case. Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
