Understanding the Psychiatric Injury Threshold in NSW CTP Claims
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).
In New South Wales, a psychiatric injury may qualify for compensation under the Compulsory Third Party (CTP) insurance scheme if it meets the legal threshold set out in the Motor Accident Injuries Act 2017 (MAIA). This threshold is not based on the severity of the psychological impact alone, but on whether the injury constitutes a 'threshold injury' as defined by law. For psychiatric injuries, this means the injury must be more than minor and must result in a significant and permanent impairment to a person’s mental health. Insurers assess these claims by examining medical evidence, the nature of the trauma, and whether the injury meets the criteria established in the Motor Accident Guidelines.
Legal Framework for Psychiatric Injury Claims
The Motor Accident Injuries Act 2017 governs all CTP claims in NSW, including those involving psychiatric injury. Under this law, a person may claim compensation for a psychiatric injury only if it qualifies as a threshold injury. This means the injury must be more than minor and must result in a permanent impairment to mental function. The law does not define 'psychiatric injury' in simple terms; instead, it relies on medical evidence and clinical assessment to determine whether the injury meets the threshold.
A psychiatric injury may be considered a threshold injury if it results in a clinically diagnosable condition such as post-traumatic stress disorder (PTSD), major depressive disorder, or an anxiety disorder that significantly impairs daily functioning. The injury must not be attributable to pre-existing mental health conditions unless it is shown to have been substantially aggravated by the motor accident. Insurers will not accept a claim based on a diagnosis alone. The injury must be supported by objective medical evidence, including assessments by a qualified mental health practitioner.
How Insurers Assess Psychiatric Injury Claims
Insurers assess psychiatric injury claims by reviewing medical reports, treatment records, and evidence of functional impairment. The assessment process is not automatic and often involves a review by an independent medical assessor (IMA) appointed by the insurer. The IMA evaluates whether the injury meets the threshold by comparing the claimant’s condition to the criteria in the Motor Accident Guidelines.
Key factors in the insurer’s assessment include:
- The nature and timing of the psychological symptoms in relation to the motor accident
- The presence of objective clinical signs, such as changes in mood, sleep disturbance, or impaired concentration
- Evidence that the injury has caused a significant and lasting impact on the claimant’s ability to work, care for themselves, or participate in daily life
- A diagnosis from a registered medical practitioner, such as a psychiatrist or clinical psychologist
Insurers may also consider whether the claimant has a history of mental health issues. If so, they will assess whether the accident caused a substantial worsening of the pre-existing condition. A claim may be rejected if the insurer determines that the injury was not caused by the accident or that the symptoms are not clinically significant.
Evidence Required to Support a Claim
To support a psychiatric injury claim under NSW CTP law, the claimant must provide clear and consistent evidence. The most critical evidence includes:
- A formal diagnosis from a registered medical practitioner, including a description of the condition and its impact on daily functioning
- Treatment records showing ongoing care, such as therapy sessions, medication, or hospital visits
- A functional capacity assessment detailing how the injury limits the claimant’s ability to perform work, household tasks, or social activities
- Statements from family members, employers, or witnesses describing changes in behaviour or performance
- A psychological assessment report that includes test results and a professional opinion on the cause and severity of the injury
Photographs of the accident scene, a police report, or witness statements may also be relevant if they help establish the traumatic nature of the event. However, these documents alone do not prove a psychiatric injury. The burden of proof rests on the claimant to demonstrate that the injury is a direct result of the motor accident and meets the legal threshold.
Time Limits and Dispute Options
There is a strict time limit for making a CTP claim in NSW. A claim must be made within three years of the motor accident. This deadline applies to all claims, including those involving psychiatric injury. Failure to meet this deadline may result in the claim being barred, unless an extension is granted by the Supreme Court of NSW under exceptional circumstances.
If an insurer denies a claim on the grounds that the psychiatric injury does not meet the threshold, the claimant may request a review of the decision. This review may be conducted internally by the insurer or, if unresolved, through an application to the State Insurance Regulatory Authority (SIRA). SIRA has the authority to review decisions and determine whether the injury meets the threshold under the Motor Accident Guidelines.
In some cases, a claimant may choose to pursue a common law damages claim if they believe the insurer’s decision is incorrect and the injury is more severe than initially assessed. However, this route requires legal representation and a higher evidentiary standard, including proof of fault and a higher level of impairment.
Hypothetical Example: A Claim Based on PTSD
A 38-year-old woman was a passenger in a car that was struck from behind while stopped at a traffic light. She sustained no physical injuries but began experiencing severe anxiety, flashbacks, and insomnia in the weeks following the accident. She was diagnosed with PTSD by a clinical psychologist and began regular therapy. Her employer confirmed she had been unable to return to work for over six months due to her condition.
She submitted a claim for treatment and care benefits, weekly income payments, and damages. The insurer initially rejected the claim, stating that the injury did not meet the threshold because there was no physical trauma and the symptoms were not severe enough. After a review by an independent medical assessor, the claim was accepted because the medical evidence demonstrated a clinically significant and lasting impairment to her mental health, and her functional capacity had been substantially reduced.
