How SIRA Handles Insurer Disputes for NSW CTP Claims (Bankstown)

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 disputing a decision by your motor accident insurer in NSW, understanding how SIRA (State Insurance Regulatory Authority) governs internal reviews is critical. SIRA sets the rules for resolving disputes under the Motor Accident Injuries Act 2017, ensuring insurers follow proper procedures before escalating claims to the Personal Injury Commission (PIC) or SIRA itself. This article explains SIRA’s guidelines for insurer internal reviews, the documentation required, and when to seek legal advice in Bankstown.

What SIRA Rules Apply to Insurer Internal Reviews?

SIRA’s rules for insurer internal reviews are outlined in its Motor Accident Claims guidelines. Insurers must first attempt to resolve disputes internally before referring claims to SIRA. Key principles include:

  • Reconsideration requests: Insurers must consider written disputes within 21 days of receiving them. This period may extend if the insurer requires additional information or medical evidence.
  • Documentation requirements: Insurers must provide claimants with written reasons for decisions, including details of any medical assessments or evidence used to determine claim outcomes.
  • Escalation criteria: If an insurer refuses to reconsider a decision or fails to respond within the 21-day window, claimants may escalate the matter to SIRA. SIRA will then assess whether the insurer’s actions comply with the Motor Accident Injuries Act 2017.

Practical Steps When Disputing an Insurer’s Decision

To challenge an insurer’s decision, claimants should:

  1. Request a written reconsideration: Submit a formal request to the insurer, clearly stating the disputed decision and the grounds for appeal. Include any new evidence, such as updated medical records or accident reports.
  1. Gather supporting documentation: Key evidence includes:
  • Medical records confirming the injury’s severity and treatment.
  • Police reports or witness statements from the accident.
  • Proof of income to support claims for weekly benefits.
  • Correspondence with the insurer showing delays or inconsistencies.
  1. Monitor the 21-day timeline: If the insurer fails to respond within 21 days, you may escalate the matter to SIRA. Note that this timeline may vary if the insurer requests additional information.

Time Limits and Dispute Resolution Timelines

Insurers must resolve disputes within 21 days of receiving a written request. If they fail to act within this period, claimants can escalate the matter to SIRA. SIRA will then review the insurer’s compliance with the Motor Accident Injuries Act 2017 and may order the insurer to reconsider the claim.

However, it’s important to note that SIRA does not guarantee a change in the insurer’s decision. The review process focuses on whether the insurer followed the correct procedures, not necessarily on overturning the original decision. Claimants should be prepared to provide clear evidence to support their case.

When to Seek Legal Advice

If your dispute involves complex medical evidence, disputes over weekly benefits, or disagreements about the extent of your injury, legal advice may be necessary. A solicitor can help you:

  • Navigate SIRA’s internal review process.
  • Challenge an insurer’s refusal to reconsider a claim.
  • File a formal complaint with SIRA if the insurer fails to comply with its obligations.

In Bankstown, claimants should also be aware that the Personal Injury Commission (PIC) may become involved if disputes escalate to the stage of formal mediation or arbitration. The PIC has specific rules for resolving disputes over claim valuations and medical assessments.

Example of a Typical Dispute Scenario

Consider a claimant who sustained a soft-tissue injury in a car accident. The insurer initially denied the claim, citing the injury as a “threshold injury” under the Motor Accident Injuries Act 2017. The claimant disputes this by providing medical evidence showing neurological signs beyond radiculopathy, as outlined in the Motor Accident Guidelines. The insurer reviews the claim internally but maintains its decision. The claimant then escalates the matter to SIRA, which reviews the insurer’s compliance with the guidelines. While SIRA may confirm the insurer followed the correct procedure, the claimant may need to pursue further legal steps to challenge the denial.

Next Steps for Claimants in Bankstown

If you’re facing an insurer dispute in Bankstown, the first step is to request a written reconsideration and gather all relevant evidence. If the insurer fails to respond within 21 days or refuses to reconsider, you may need to escalate the matter to SIRA. Remember that SIRA’s role is to ensure insurers follow the correct procedures, not to guarantee a change in their decision. For complex disputes, seeking legal advice is often the best course of action.
