Claims Assessors in NSW CTP Disputes: Resolution Options for Western Sydney

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 New South Wales and disagree with a claims assessor's decision, understanding your dispute resolution options is critical. Claims assessors evaluate claims under the Motor Accident Injuries Act 2017 and SIRA guidelines to determine compensation entitlements. This article explains their role, available dispute pathways, and how to challenge decisions in Western Sydney.

What is a Claims Assessor and Their Role?

A claims assessor is an independent professional appointed by the State Insurance Regulatory Authority (SIRA) to evaluate claims under the NSW Compulsory Third Party (CTP) scheme. Their role is to determine whether a claimant meets the criteria for compensation, including:

  • Whether the injury qualifies as a 'threshold injury' under the Motor Accident Guidelines
  • The level of weekly benefits or treatment and care payments
  • Whether the claimant is eligible for a damages claim

Assessors rely on medical evidence, accident reports, and SIRA guidelines to make decisions. Their findings are binding unless challenged through the formal dispute process.

Dispute Resolution Options for Claims Assessors

If you disagree with a claims assessor's decision, you have several options to challenge it:

#### 1. Internal Review by SIRA

The first step is to request an internal review of the assessor's decision. SIRA will reassess the claim based on new evidence or a reassessment of existing evidence. This process typically takes 28 days from the date of the request.

#### 2. Medical Dispute Pathway

If the dispute involves medical evidence (e.g., whether an injury meets the threshold injury definition), you can refer the matter to the Personal Injury Commission (PIC) for a medical review. The PIC will appoint an independent medical expert to evaluate the claimant's condition. This pathway is particularly relevant for disputes over 'whole person impairment' or 'spinal nerve-root injuries' under the Motor Accident Guidelines.

#### 3. External Review by the NSW Civil and Administrative Tribunal (NCAT)

If the internal review and medical dispute pathway do not resolve the issue, you can apply to NCAT for an external review. NCAT will assess whether the assessor's decision was legally sound and may overturn or amend the finding. This is the final dispute resolution option under the CTP scheme.

How SIRA Guidelines Shape Assessor Decisions

SIRA's Motor Accident Guidelines provide the framework for claims assessors to evaluate injuries. Key principles include:

  • Threshold injuries must meet specific clinical criteria, such as neurological signs or functional limitations. For example, a spinal nerve-root injury producing neurological signs (even without radiculopathy) may still qualify as a threshold injury.
  • Weekly benefits are limited to 52 weeks for claims where the only injuries are threshold injuries. After this period, benefits are generally discontinued unless the claimant has a 'whole person impairment' of 10% or more.
  • Damages claims are only available if the injury exceeds the threshold injury definition and the claimant can prove a 'significant and lasting impairment' under the guidelines.

Understanding these guidelines is essential when challenging an assessor's decision. For instance, if the assessor incorrectly excludes a spinal injury from the threshold injury definition, you may need to provide additional medical evidence to support your case.

Practical Steps for Challenging a Claims Assessor's Decision

To effectively challenge a claims assessor's decision, take the following steps:

  1. Review the Assessor's Report: Carefully examine the assessor's reasoning, including their interpretation of medical evidence and SIRA guidelines. Look for errors in clinical judgment or misapplication of the guidelines.
  1. Gather Supporting Evidence: Collect all relevant documents, including:
  • Medical records from your treating practitioners
  • Accident reports and witness statements
  • Income records to support claims for weekly benefits
  • Correspondence with the insurer or SIRA
  1. Request an Internal Review: Submit a written request for an internal review within 28 days of receiving the assessor's decision. Clearly outline why you believe the decision is incorrect.
  1. Engage the Medical Dispute Pathway: If the dispute involves medical evidence, apply to the PIC for a medical review. This may require a second opinion from an independent medical expert.
  1. Seek External Review by NCAT: If the internal review and medical dispute pathway fail to resolve the issue, apply to NCAT for an external review. This process can take several months, so it's important to act promptly.

Example: Challenging a Threshold Injury Decision

Consider a scenario where a claimant suffers a minor car accident and is diagnosed with a herniated disc. The claims assessor determines this is not a threshold injury and denies weekly benefits. However, the claimant's MRI shows neurological signs consistent with a spinal nerve-root injury. In this case, the claimant can challenge the decision by:

  • Providing the MRI report to SIRA
  • Requesting an internal review to reassess the injury's classification
  • Applying to the PIC for a medical review to confirm whether the injury meets the threshold criteria

This example highlights how accurate medical evidence and a thorough understanding of SIRA guidelines can influence the outcome of a dispute.

When to Seek Legal Advice

While the dispute resolution process is designed to be independent, it can be complex. If you're unsure whether your claim meets the threshold injury definition, or if you need assistance preparing a challenge, it's advisable to seek legal advice. A solicitor can help you:

  • Navigate the internal review and medical dispute pathways
  • Prepare a strong case for an external review by NCAT
  • Understand your rights under the Motor Accident Injuries Act 2017

Final Notes on Dispute Resolution

Disputing a claims assessor's decision is not guaranteed to result in a changed outcome. The assessor's decision must be legally sound and supported by medical evidence. It's important to act quickly, as time limits apply to each stage of the dispute process. If you're in Western Sydney and need assistance with a CTP dispute, contact a legal professional to explore your options.
