Why Insurers Deny CTP Claims in NSW, What Claimants Need to Know

Insurers in NSW may deny CTP claims based on injury type, fault, or procedural issues under the Motor Accident Injuries Act 2017. SIRA guidelines shape these decisions, particularly on threshold injuries and medical evidence. Claimants can challenge denials through review processes, NCAT, or legal advice. Time limits and evidence quality are critical to success.

Understanding CTP Claim Denials in NSW

When an insurer in New South Wales denies a Compulsory Third Party (CTP) claim, it often stems from a legal assessment under the Motor Accident Injuries Act 2017 (MAIA). Insurers may refuse liability or benefits based on factors such as the nature of the injury, the claimant’s fault, or the absence of a qualifying injury. These decisions are not arbitrary. They are governed by statutory criteria and must follow the Motor Accident Injuries Regulation 2017 and the Motor Accident Guidelines issued by the State Insurance Regulatory Authority (SIRA). In Greater Sydney and across NSW, claimants who believe a denial is incorrect have rights to challenge it through formal review processes.

Legal Grounds for CTP Claim Denial

Insurers may deny a CTP claim for several legally recognised reasons. The most common include:

  • The injury does not meet the threshold for compensation under MAIA, particularly if it is a soft tissue injury without qualifying neurological signs.
  • The claimant contributed to the accident through their own negligence, which may reduce or bar entitlement.
  • The claimant failed to provide sufficient medical evidence to support the injury or its impact on daily life.
  • The claim was made outside the applicable time limits, which are generally three years from the date of the accident.
  • The insurer disputes liability, particularly in cases involving pedestrians, cyclists, or incidents on private property where the legal status of the motor vehicle use may be contested.

A denial based on the claimant’s fault does not automatically bar recovery. Under the MAIA, a claimant may still be entitled to treatment and care benefits and weekly income payments if they are not more than 50% at fault. However, entitlement to damages for pain and suffering or loss of income may be reduced proportionally.

How SIRA Guidelines Influence Insurer Decisions

SIRA’s Motor Accident Guidelines provide detailed direction on how insurers must assess claims. These guidelines are not law, but they are a key factor in determining whether an insurer’s decision is reasonable and defensible. For example, the guidelines clarify when a soft tissue injury qualifies as a threshold injury, particularly in relation to spinal nerve-root injuries. An injury must show objective clinical signs, such as a loss of reflex, muscle weakness, or sensory change, beyond simple radiculopathy to be considered a threshold injury under the guidelines.

Insurers must also follow the principle that a claimant’s only injuries must not be limited to threshold injuries if they are to claim damages. If a claimant’s only injuries are threshold injuries, damages are generally restricted under section 4.4 of the MAIA. This restriction applies regardless of the severity of symptoms, and insurers rely on this provision to deny claims for damages.

Evidence That Matters in Challenging a Denial

When challenging a CTP claim denial, the quality and type of evidence are critical. Insurers assess claims based on objective medical documentation. Key evidence includes:

  • A detailed medical report from a treating practitioner, including diagnosis, treatment plan, and assessment of functional impact.
  • Imaging results (e.g. MRI, CT scans) showing structural injury, particularly in the spine or joints.
  • A functional capacity assessment or independent medical examination (IME) report, if available.
  • Records of treatment, including dates, procedures, and outcomes.
  • Evidence of income loss, such as payslips, employer letters, or tax returns.
  • Photographic or video evidence of the accident scene, vehicle damage, or visible injuries.
  • Witness statements, particularly if the claimant was a pedestrian or cyclist.

Failure to preserve and submit this evidence within a reasonable timeframe may result in a claim being dismissed, even if the injury is genuine.

Practical Steps to Challenge a Denial

If an insurer denies a CTP claim, the claimant should act promptly. The first step is to obtain a written explanation of the denial from the insurer. This letter must state the grounds for refusal and reference the relevant sections of the MAIA or SIRA guidelines.

Next, the claimant may request a review of the decision under the insurer’s internal dispute resolution process. This must be done within 28 days of receiving the denial letter. If the review is unsuccessful, the claimant may apply to the Civil and Administrative Tribunal (NCAT) for a determination. NCAT has jurisdiction to review CTP decisions, including those on liability, benefits, and damages.

A claimant may also seek legal advice at any stage. While a solicitor cannot guarantee a successful outcome, they can assess whether the insurer’s decision was legally sound, identify gaps in evidence, and assist in preparing a formal application to NCAT.

Time Limits and Procedural Deadlines

Time is critical in CTP claims. The general time limit for making a claim is three years from the date of the motor accident. However, if the claimant is under 18 at the time of the accident, the time limit extends to three years after their 18th birthday.

There are also procedural deadlines within the CTP process. For example, a claimant must notify the insurer of their intention to claim within 60 days of the accident, or within 60 days of becoming aware of the injury, whichever is later. Failure to meet this deadline may result in a claim being barred, even if the injury is valid.

Hypothetical Example: A Claimant’s Path After Denial

A 34-year-old cyclist in Sydney was struck by a car at a traffic light in February 2025. The insurer denied the claim on the grounds that the neck injury was a soft tissue injury without objective signs of nerve damage, and that the claimant had contributed to the accident by not wearing a helmet. The claimant had a medical report showing a cervical disc injury on MRI, but no documented loss of reflex. The insurer refused treatment and care benefits.

The claimant obtained a second opinion from a specialist neurologist, who confirmed a spinal nerve-root injury with objective signs of sensory disturbance. The claimant submitted this report, along with a detailed diary of symptoms and a statement from a witness, to the insurer. After a review, the insurer reversed its decision and agreed to provide treatment and care benefits. The claimant later applied for damages, which were approved after a medical assessment confirmed a whole person impairment of 12%.

When to Seek Independent Advice

A CTP claim denial does not mean the claim is hopeless. Many denials are based on incomplete evidence, misapplication of the guidelines, or procedural errors. However, the legal framework is complex, and insurers have significant discretion in interpreting the law and guidelines.

Claimants should seek independent advice if:

  • The insurer’s denial is not supported by medical evidence.
  • The claimant believes they were unfairly blamed for the accident.
  • The insurer refuses to provide benefits despite a confirmed injury.
  • The claimant is unsure about the next steps or how to submit evidence.
