Insurers may deny CTP claims in NSW by disputing injury severity or eligibility. Changes after the 2017 reforms include stricter rules on threshold injuries and 52-week limits for benefits. Claimants should gather medical evidence, challenge denials within 28 days, and seek legal advice if needed.

How Insurers Deny CTP Claims in NSW

Insurers may deny or limit compensation claims under the NSW Compulsory Third Party (CTP) scheme by disputing the nature of injuries, the claimant’s eligibility, or the availability of benefits. After the 2017 reforms, changes to the Motor Accident Injuries Act 2017 and SIRA guidelines have altered how insurers assess claims, particularly for injuries deemed 'threshold injuries' or claims involving soft tissue damage.

Key Changes to CTP Claims After 2017

The 2017 reforms introduced significant shifts in how claims are evaluated. Under the new rules, insurers can now deny or reduce benefits if a claimant’s injuries fall below the 'threshold injury' definition. This includes injuries like whiplash, soft tissue damage, or minor fractures that do not meet the specific clinical criteria outlined in the Motor Accident Guidelines. Additionally, the reforms clarified that weekly income payments and treatment benefits are generally limited to 52 weeks after an accident, unless the claimant has a whole person impairment rating of 10% or more.

How Insurers Typically Deny Claims

Insurers often deny claims by:

  • Arguing the injury does not meet the 'threshold injury' definition
  • Claiming the injury is not a 'threshold injury' due to lack of clinical evidence
  • Refusing to pay for treatment or income support after 52 weeks
  • Disputing the claimant’s eligibility based on fault or contributory negligence

These denials are often based on interpretations of the Motor Accident Injuries Act 2017 and SIRA’s guidelines, which emphasize objective medical evidence over subjective claims.

Practical Steps for Claimants

If an insurer denies your claim, take these steps:

  • Review the denial letter to understand the specific reason for rejection.
  • Gather medical evidence showing your injury meets the threshold criteria, including clinical notes from a medical practitioner.
  • Submit a formal review request to SIRA within 28 days of the denial.
  • Seek independent medical assessment if the insurer disputes the severity of your injury.
  • Consider mediation through SIRA’s dispute resolution process.

Time Limits and Dispute Options

Claimants must act quickly. Under the 2017 reforms, you have:

  • 28 days to challenge an insurer’s denial of benefits
  • 52 weeks to claim weekly income support or treatment benefits unless you have a whole person impairment rating of 10% or more

If the insurer refuses to pay, you can:

  • Lodge a review with SIRA
  • Apply for mediation through the NSW Civil and Administrative Tribunal (NCAT)
  • Seek legal advice if the insurer’s denial is based on incorrect interpretations of the law

When to Seek Legal Advice

Consult a solicitor if:

  • The insurer denies your claim based on a misinterpretation of the law
  • You have a whole person impairment rating of 10% or more
  • You need help challenging a denial of weekly income support or treatment benefits
  • You believe the insurer is acting in bad faith

Example: Threshold Injury Denial

Consider a claimant who suffered a soft tissue injury in a car accident. The insurer denies benefits, arguing the injury does not meet the threshold definition. Under the 2017 reforms, the claimant must provide clinical evidence showing a spinal nerve-root injury with neurological signs, as outlined in the Motor Accident Guidelines. If the evidence supports a threshold injury, the claimant may reapply for benefits.

Next Steps

CTP claim denials can be complex, especially after the 2017 reforms. Time limits, evidence requirements, and legal interpretations play a critical role in determining the outcome. To request contact about your circumstances, complete the quick, no obligation enquiry form.
