If you're involved in a dispute with your CTP insurer over a green slip claim in NSW, understanding the PIC's (Personal Injury Claimant's) expectations is critical. This article explains what claimants can reasonably expect during disputes, based on SIRA guidelines and NSW law. It covers practical steps, evidence requirements, and how to challenge decisions without overreaching.

What the PIC Can Expect During CTP Disputes

Under the Motor Accident Injuries Act 2017 (MAIA), CTP insurers must assess claims based on medical evidence and statutory guidelines. If your claim is disputed, the PIC can expect:

  • A written explanation of the insurer's decision, including the reasons for denying or limiting benefits.
  • Access to SIRA's claims process to challenge decisions, including internal reviews and formal disputes.
  • A timeline for resolving disputes, typically 28 days for internal reviews under SIRA's guidelines.
  • No automatic right to challenge decisions without following the correct procedural steps.

Insurers may dispute claims on grounds such as lack of medical evidence, failure to meet threshold injury criteria, or disputes over weekly income payments. The PIC must provide supporting documentation to counter these claims.

Practical Steps for PICs in Disputes

To resolve disputes effectively, PICs should:

  1. Review the insurer's decision letter to identify specific objections. For example, if the insurer disputes a claim for soft tissue injury, the PIC must provide medical records confirming neurological signs as defined in the Motor Accident Guidelines.
  1. Submit a formal dispute request through SIRA's claims portal within 28 days of receiving the decision. This triggers an internal review by the insurer.
  1. Gather evidence such as medical reports, accident records, and witness statements. For instance, if the insurer disputes a claim for a spinal nerve-root injury, the PIC must show clinical signs beyond radiculopathy as outlined in SIRA's guidelines.
  1. Seek independent medical advice if the insurer's assessment conflicts with your treating practitioner's opinion. This can strengthen the PIC's case during disputes.

Time Limits and Dispute Resolution

CTP claims must be made within 52 weeks of the accident under the MAIA. However, disputes can extend beyond this period if the insurer's decision is appealed. Key deadlines include:

  • 28 days to request an internal review of a disputed decision.
  • 30 days to escalate disputes to the NSW Civil and Administrative Tribunal (NCAT) if the insurer refuses to reconsider.

If the insurer's decision is challenged through NCAT, the PIC must demonstrate that the original assessment was based on incorrect medical evidence or misinterpretation of the guidelines. SIRA's internal review process is the first step before external dispute resolution.

Example: Challenging a Threshold Injury Dispute

Suppose a PIC claims a soft tissue injury after a car accident, but the insurer disputes it as below the threshold. The PIC must provide:

  • A medical report confirming neurological signs such as sensory or motor loss.
  • Evidence that the injury meets the spinal nerve-root criteria in the Motor Accident Guidelines.

If the insurer still denies the claim, the PIC can request an internal review, citing the specific medical evidence. This process allows for a formal challenge without prematurely escalating to NCAT.

When to Seek Legal Advice

Disputes can become complex, especially if the insurer refuses to engage with the claims process. A solicitor can help:

  • Navigate SIRA's dispute resolution pathways.
  • Challenge the insurer's interpretation of medical evidence.
  • Ensure compliance with time limits for internal reviews and NCAT applications.

However, legal advice is not required for all disputes. Many claims can be resolved through SIRA's internal review process without external representation.

Next Steps for PICs

If your CTP claim is disputed, act promptly to challenge the decision using SIRA's guidelines. Document all communications with the insurer and ensure you meet all procedural deadlines. Remember, the PIC's expectations are tied to the evidence and statutory framework, not to the insurer's willingness to negotiate.
