How Insurers Deny CTP Claims in NSW

Insurers often deny Compulsory Third Party (CTP) claims in New South Wales by disputing the injury's eligibility, the claimant's entitlement to benefits, or the claim's validity under the Motor Accident Injuries Act 2017. Common reasons include injuries falling below the 'threshold injury' definition, disputes over fault, or failure to meet statutory deadlines. For example, an insurer might deny a claim if the injury is classified as a soft tissue injury without meeting the spinal nerve-root criteria outlined in the Motor Accident Guidelines.

Key NSW CTP Rules Behind Claim Denials

The Motor Accident Injuries Act 2017 governs CTP claims, with specific sections addressing injury thresholds and benefit limits. Under s 4.4, weekly benefits and treatment benefits are generally limited after 52 weeks if the injury is a 'threshold injury', a term defined in the Motor Accident Guidelines. Insurers may also deny claims if the injury does not meet the 'whole person impairment' threshold or if the claimant fails to provide sufficient evidence of injury.

Practical Steps to Challenge Denied Claims

If your claim is denied, take these steps:

  • Gather medical evidence: Ensure your treating medical practitioner documents neurological signs or radiculopathy as required by the Motor Accident Guidelines.
  • Review the denial letter: Insurers must provide reasons for denial, such as 'no threshold injury' or 'insufficient evidence of fault'.
  • Submit a dispute: Use the 'Dispute a Decision' form on the SIRA website (https://www.sira.nsw.gov.au/claims/motor-accidents/dispute-a-decision) to challenge the insurer's decision.
  • Seek independent medical opinion: A second opinion may be needed to prove the injury meets the threshold.

Time Limits and Dispute Options

CTP claims must be submitted within 52 weeks of the accident if the injury is a threshold injury. For non-threshold injuries, there is no strict time limit, but delays may affect benefit eligibility. If the insurer denies your claim, you have 28 days to dispute the decision under s 12 of the Motor Accident Injuries Act 2017. If the dispute is unresolved, you may need to escalate to the NSW Civil and Administrative Tribunal (NCAT) or seek legal advice.

Example: Denied Claim in Western Sydney

Consider a claimant in Western Sydney who sustained a soft tissue injury after a car accident. The insurer denied the claim, arguing the injury did not meet the threshold injury definition. The claimant submitted medical records showing spinal nerve-root injury with neurological signs, which aligned with the Motor Accident Guidelines. After a dispute, the insurer agreed the injury qualified, and the claimant received weekly benefits.

If your claim is denied and you're unsure how to proceed, consult a solicitor specialising in CTP claims. They can help you:

  • Interpret the Motor Accident Guidelines
  • Navigate the SIRA dispute process
  • Challenge the insurer's decision using legal remedies
