How Insurers Evaluate CTP Claims During Internal Reviews

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).

Insurers in New South Wales assess liability for Compulsory Third Party (CTP) claims by applying the Motor Accident Injuries Act 2017 and SIRA guidelines. When a claimant disputes an insurer's decision, the insurer first conducts an internal review to reassess the claim's validity. This process involves evaluating medical evidence, fault, and compliance with statutory rules.

Key Factors in Insurer Liability Assessments

Insurers consider several factors when determining liability during internal reviews. These include:

  • Nature of the injury: Whether the injury meets the 'threshold injury' definition under the Motor Accident Injuries Act 2017.
  • Fault determination: Whether the accident involved a motor vehicle and if the claimant's actions contributed to the incident.
  • Medical evidence: Whether the injury is supported by clinical records and aligns with SIRA's guidelines.
  • Statutory benefits: Whether the claimant qualifies for weekly payments, treatment benefits, or lump sum damages.

Insurers also check if the claimant has followed the correct process, such as notifying the insurer within the required time frame and providing necessary documentation.

How to Challenge an Insurer's Decision in Ballina

If an insurer denies or reduces a claim, the claimant can request an internal review. This involves:

  1. Writing to the insurer: Requesting a reconsideration of the decision, citing specific reasons for disagreement.
  2. Providing evidence: Submitting additional medical records, accident reports, or witness statements to support the claim.
  3. Escalating to SIRA: If the internal review is unsatisfactory, the claimant can escalate the matter to the State Insurance Regulatory Authority (SIRA) within 28 days.

It's important to note that SIRA does not provide legal advice but ensures insurers comply with the law. Claimants should also consider whether a medical dispute requires the Personal Injury Commission (PIC) to review the injury's severity.

Time Limits and Dispute Resolution

CTP claims have strict time limits. For example, weekly benefits are generally limited to 52 weeks if the injury is a 'threshold injury' (s 4.4 of the Motor Accident Injuries Act 2017). If the claimant believes the insurer has misapplied the rules, they must act quickly. The 28-day deadline to escalate to SIRA is critical, as delays can result in lost entitlements.

Disputes often arise over whether the injury meets the 'threshold injury' definition. SIRA's guidelines state that injuries must involve 'spinal nerve-root injury producing neurological signs' or other specified clinical signs. Claimants should ensure their medical records clearly document these criteria.

Practical Steps for Claimants

To strengthen a claim during an internal review, claimants should:

  • Gather medical records: Ensure all clinical notes, imaging, and specialist reports are available.
  • Document the accident: Include police reports, witness statements, and photographs of the scene.
  • Track income and expenses: Keep records of lost wages, medical costs, and other financial impacts.
  • Seek independent advice: A solicitor can help identify gaps in the claim and advise on the best course of action.

When to Seek Legal Advice

Claimants should consider legal assistance if:

  • The insurer refuses to acknowledge a 'threshold injury'.
  • The claimant is unsure whether the injury qualifies for damages.
  • The internal review process is taking longer than expected.

Legal professionals can also help navigate the PIC's medical dispute pathway, which is required for claims involving 'whole person impairment' or long-term care needs.

Conclusion

Insurers in Ballina assess CTP claims based on statutory rules and SIRA guidelines. While internal reviews offer an opportunity to challenge decisions, claimants must act promptly and provide clear evidence.
