What to Do When a CTP Insurer Denies Your Claim in NSW

If your insurer has denied your Compulsory Third Party (CTP) claim in New South Wales, you may be wondering what changed after the 2017 reforms. The reforms introduced by the Motor Accident Injuries Act 2017 (MAIA) significantly altered how claims are assessed, particularly for injuries deemed 'threshold injuries' and the calculation of weekly benefits. Understanding these changes is critical to challenging a denial.

Key Changes to CTP Claim Handling After 2017

The 2017 reforms replaced the old Motor Accidents Compensation Act 1999 (MACA) with the MAIA, shifting the focus from fault-based claims to a system based on injury severity. Under the new rules:

  • Threshold injuries are defined as injuries requiring medical treatment, such as soft tissue injuries, fractures, or minor head injuries. These injuries now qualify for benefits under the MAIA, even if the claimant is not at fault.
  • Weekly benefits are calculated based on the claimant’s income, with a maximum of 80% of their weekly earnings. Insurers must now assess claims using the Motor Accident Guidelines to determine the appropriate level of compensation.
  • SIRA (State Insurance Regulatory Authority) now oversees the administration of CTP claims, ensuring insurers comply with the new rules. SIRA’s guidelines clarify how to assess injuries and calculate benefits, reducing ambiguity in claim denials.

How SIRA Guides Denied Claims

SIRA plays a central role in resolving disputes over denied claims. If an insurer denies a claim, they must provide a written explanation based on the Motor Accident Guidelines. Claimants can challenge the denial by:

  1. Reviewing the insurer’s reasoning: Insurers must specify whether the claimant’s injuries fall below the threshold or if the benefits calculation is incorrect.
  1. Providing additional evidence: Medical records, accident reports, and witness statements can support a claim. SIRA requires insurers to consider all relevant evidence before denying a claim.
  1. Requesting a review: Claimants can ask the insurer to reconsider their decision in writing. If the insurer refuses, they may escalate the matter to SIRA.

Practical Steps for Claimants

If your claim has been denied, take these steps:

  • Document the denial: Keep a copy of the insurer’s letter explaining the denial. Note any discrepancies or unclear reasoning.
  • Gather medical evidence: Ensure your medical records clearly show the injury and its impact. SIRA requires evidence of treatment and a diagnosis of a threshold injury.
  • Seek clarification: Contact the insurer to ask for a detailed explanation of why your claim was denied. Request a copy of the Motor Accident Guidelines they used to assess your case.
  • Consult SIRA: If the insurer refuses to reconsider, contact SIRA directly. They can mediate disputes and ensure insurers comply with the law.

Example of a Denied Claim

Consider a claimant who suffered a soft tissue injury in a car accident. The insurer denies the claim, arguing the injury does not meet the threshold. However, under the MAIA, a soft tissue injury qualifies as a threshold injury if it requires medical treatment. The claimant can challenge the denial by providing a medical report confirming the injury and its treatment.

Time Limits and Dispute Options

CTP claims must be made within a specific timeframe. If the accident occurred before 1 December 2017, the old MACA rules may apply, but the MAIA governs claims from that date onward. Always check the accident date to determine the correct legal framework.

If a claim is denied, you have the right to dispute the decision. SIRA provides a formal process for resolving disputes, and claimants can also seek legal advice if needed.

When to Seek Legal Advice

While SIRA provides a pathway for resolving disputes, complex cases may require legal assistance. A solicitor can help you:

  • Challenge the insurer’s interpretation of the
  • Motor Accident Guidelines*.
  • Navigate the administrative process for disputes.
  • Ensure you meet all deadlines for filing a claim or dispute.

Next Steps

CTP claim denials can be challenging, but understanding the changes introduced by the 2017 reforms gives you a stronger position. If your claim has been denied, take the time to review the insurer’s reasoning, gather evidence, and seek assistance from SIRA or a legal professional. Every claim depends on its own facts, and the right approach can make a significant difference.
