What is the psychiatric injury threshold under NSW CTP laws?
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 emotional distress alone, but on whether the injury is considered a 'threshold injury', a category that includes certain psychological conditions that are more than minor. The law defines a threshold injury as one that results in a permanent impairment of at least 10% of the whole person, or a condition that causes significant and lasting functional impact. For psychiatric injuries, this means the condition must be clinically diagnosed, medically substantiated, and have a measurable effect on daily life, work, or relationships.
How does SIRA determine if a psychiatric injury meets the threshold?
The State Insurance Regulatory Authority (SIRA) uses the Motor Accident Guidelines to assess whether a psychiatric injury meets the threshold. These guidelines require that the injury be caused by a motor accident and not pre-exist or be unrelated to the incident. The assessment considers whether the injury results in a clinically recognised condition, such as post-traumatic stress disorder (PTSD), major depressive disorder, or anxiety disorders, that persists beyond a short period and significantly impairs the person’s ability to function.
A key factor is whether the injury has caused a permanent impairment of at least 10% of the whole person. This is determined through a formal assessment by an independent medical practitioner, using the Australian Institute of Health and Welfare (AIHW) impairment assessment standards. The assessment must show that the psychological condition is not transient, and that it is directly attributable to the motor accident. SIRA does not accept claims where the injury is solely emotional or psychological without objective medical evidence of lasting functional impact.
What evidence is required to claim a psychiatric injury under CTP laws?
To establish a psychiatric injury that meets the threshold, claimants must provide clear and credible evidence. This includes:
- A formal diagnosis from a registered medical practitioner, such as a psychiatrist or clinical psychologist, confirming the presence of a clinically recognised psychiatric condition.
- Medical records documenting the onset and progression of symptoms, including treatment history, medication, and therapy sessions.
- Evidence of functional impairment, such as inability to work, loss of daily functioning, or changes in relationships, supported by statements from employers, family members, or healthcare providers.
- A whole person impairment (WPI) assessment conducted by an independent medical assessor, which determines the percentage of permanent impairment.
Photographs of the accident scene, witness statements, and a police report (if applicable) may also help establish the circumstances of the accident and support the claim that the injury was caused by the motor vehicle incident. It is essential to preserve all documentation and seek medical attention promptly after the accident, as delays may affect the credibility of the claim.
How does the threshold affect compensation for injured claimants?
If a psychiatric injury meets the threshold, the claimant may be entitled to several forms of compensation under the CTP scheme. These include:
- Weekly income payments, if the injury prevents the person from working and they have lost income.
- Treatment and care benefits, to cover the cost of ongoing psychological treatment, counselling, and medication.
- Damages for pain and suffering, if the injury is permanent and the claimant has a WPI of 10% or more.
However, if the psychiatric injury is classified as a threshold injury and no other non-threshold injuries are present, the right to claim damages for pain and suffering is restricted. Under the MAIA, a claimant who has only threshold injuries may not recover damages for pain and suffering unless they can demonstrate a permanent impairment of at least 10% and that the injury has significantly affected their life.
This 52-week rule applies only to claims where the only injuries are threshold injuries, and it does not apply if there are non-threshold injuries (such as a broken bone or spinal injury) that justify ongoing support.
Practical steps and when to seek advice
If you believe you have suffered a psychiatric injury as a result of a motor accident in NSW, you should:
- Seek medical assessment from a mental health professional as soon as possible.
- Contact your CTP insurer or the SIRA claims portal to report the injury and begin the claims process.
- Keep detailed records of all treatment, symptoms, and functional limitations.
- Provide all relevant evidence to support your claim, including medical reports, employment records, and witness statements.
A common mistake is assuming that emotional distress alone qualifies for compensation. The law requires more than emotional upset, it requires a diagnosable condition with lasting impact. If you are unsure whether your injury meets the threshold, or if you are facing a dispute over your claim, it is advisable to seek independent legal advice.
Hypothetical example
A 38-year-old woman was involved in a rear-end collision while driving to work. She was not physically injured but began experiencing severe anxiety, panic attacks, and sleep disturbances shortly after. After six months of therapy and a formal diagnosis of PTSD, she underwent a WPI assessment that confirmed a 12% impairment. Her claim was accepted under the CTP scheme, and she received weekly payments, treatment coverage, and damages for pain and suffering. The claim was successful because the injury met the threshold and was supported by medical evidence and functional impact.
