How Insurers Review Claims in NSW CTP Cases

Insurers in NSW evaluate CTP claims using the Motor Accident Injuries Act 2017 and SIRA guidelines. Claimants can challenge decisions by submitting medical evidence, escalating to SIRA, or seeking legal advice. Understanding the internal review process is key to securing fair compensation.

Current as at 17 October 2026

Insurers in New South Wales evaluate claims through internal reviews to determine if a motor accident claim meets the criteria for compensation under the Motor Accident Injuries Act 2017 (MAIA). These reviews assess whether injuries qualify as threshold injuries, whether benefits are owed, and whether claims align with SIRA guidelines. Understanding this process is critical for claimants seeking to challenge decisions or escalate disputes. This article explains how insurers make decisions during internal reviews, what evidence matters, and when to seek further action.

The Legal Framework Behind Insurer Reviews

Under the MAIA, insurers must assess claims based on objective medical evidence and statutory criteria. SIRA (State Insurance Regulatory Authority) oversees the CTP scheme and provides guidelines for insurers to evaluate claims. Key factors include:

  • Whether the injury meets the 'threshold injury' definition in the Motor Accident Guidelines (e.g., soft tissue injuries with neurological signs).
  • Whether the claimant is eligible for weekly benefits, treatment and care benefits, or lump sum damages.
  • Whether the injury resulted from the accident and is not attributable to other causes.

Insurers must apply these rules consistently, though claimants may challenge decisions if they believe evidence was overlooked or misinterpreted.

Practical Steps for Claimants During Internal Reviews

When an insurer rejects a claim or limits benefits, claimants should take the following steps to understand or challenge the decision:

  1. Review the Decision Letter: Insurers must provide reasons for rejecting or modifying a claim. Look for references to medical evidence, injury thresholds, or statutory limits.
  1. Submit Additional Evidence: If the insurer missed key details (e.g., a medical report confirming a threshold injury), claimants can request a review by submitting new evidence. This includes:
  • Detailed medical records from GPs, specialists, or physiotherapists.
  • Accident reports, witness statements, or photographs.
  • Income records to support claims for weekly benefits.
  1. Escalate to SIRA: If the insurer refuses to reconsider, claimants can escalate the matter to SIRA. SIRA has the authority to review claims and override insurer decisions if they find errors in the assessment.
  1. Seek Independent Medical Advice: Disputes over injury severity or treatment often require a second opinion. A medical practitioner can provide evidence to challenge the insurer's interpretation of the guidelines.

Time Limits and When to Challenge Decisions

Insurers must respond to claims within specific timeframes. For example, weekly benefits must be paid from the first day of treatment, and insurers cannot unreasonably delay decisions. If an insurer fails to act within these limits, claimants may have grounds to challenge the delay as a breach of the MAIA.

Claimants should also be aware of the 52-week statutory limit for weekly benefits. If a claimant's only injuries are threshold injuries, benefits may stop after 52 weeks. However, if the injury is classified as a whole person impairment (WPI) of 10% or more, benefits may continue beyond this period.

Example: Challenging a Threshold Injury Decision

Consider a claimant who suffered a soft tissue injury after a car accident. The insurer rejects the claim, arguing it does not meet the threshold injury definition. The claimant can challenge this by submitting a medical report from a specialist confirming neurological signs (e.g., a spinal nerve-root injury with radiculopathy). This evidence may demonstrate the injury qualifies under the guidelines, prompting the insurer to reconsider.

When to Seek Legal Advice

While claimants can challenge decisions using the above steps, complex disputes may require legal assistance. A solicitor can help draft formal disputes, navigate SIRA's review process, or challenge decisions based on statutory interpretation. Legal advice is particularly useful when:

  • The claimant believes the insurer misapplied the guidelines.
  • The injury involves long-term or permanent impairment.
  • The claimant faces a dispute over medical evidence or treatment.

Next Steps for Claimants

Understanding how insurers evaluate claims is essential for securing fair compensation. If you believe your claim was wrongly assessed or limited, take action by submitting additional evidence, escalating to SIRA, or seeking legal advice. Every claim depends on its own facts, and the right steps can make a significant difference in the outcome.
