Psychiatric Injury Threshold in NSW CTP Scheme
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).
A psychiatric injury claim under the NSW Compulsory Third Party (CTP) scheme may be eligible for compensation if it meets the legal threshold for serious injury. This threshold applies to psychological injuries that are not minor and require treatment beyond basic medical care. In Greater Sydney, as elsewhere in NSW, eligibility depends on whether the injury results in a permanent impairment or significantly affects daily life and capacity to work. The Motor Accident Injuries Act 2017 (MAIA) governs the current CTP scheme and defines the criteria for such claims.
What Constitutes a Threshold Psychiatric Injury?
Under the MAIA, a psychiatric injury qualifies as a threshold injury if it causes a permanent impairment of at least 10% of the whole person. This assessment is made by a qualified medical practitioner using the Australian National Injury and Impairment Guidelines (the Guidelines). The injury must be directly caused by the motor accident and not pre-existing or unrelated to the trauma. Common qualifying conditions include post-traumatic stress disorder (PTSD), major depressive disorder, or anxiety disorders that persist beyond the initial recovery phase and require ongoing treatment.
The Guidelines specify that a psychiatric injury may still meet the threshold even if it does not involve physical trauma. However, the injury must be clinically diagnosed and supported by medical evidence showing functional impairment. For example, an injury that prevents a person from returning to work, disrupts relationships, or causes significant distress over a sustained period may be considered threshold-level.
Evidence Required to Establish Eligibility
To establish eligibility, claimants must provide objective medical evidence. This includes:
- A formal diagnosis from a registered medical practitioner, such as a psychiatrist or clinical psychologist, confirming the presence of a diagnosable psychiatric condition.
- A whole person impairment (WPI) assessment conducted by an independent medical assessor, which determines the percentage of permanent impairment.
- Treatment records showing ongoing therapy, medication, or psychological support for at least 12 months post-accident.
- A narrative from the claimant detailing how the injury has affected daily functioning, including work, family life, and personal activities.
Photographs of the accident scene, witness statements, and police reports may also support the claim by establishing the traumatic nature of the event. In Greater Sydney, where motor vehicle traffic is dense and road incidents common, evidence of sudden impact, near-miss events, or witnessing a serious crash can be critical to proving the psychological trigger.
Time Limits and Procedural Steps
A claim for a threshold psychiatric injury must be made within the time limits set by the MAIA. While the general time limit for initiating a claim is three years from the accident date, the claimant must notify the insurer within 60 days of the accident to preserve rights to treatment and care benefits. Failure to notify within this period may result in the insurer refusing to cover treatment costs.
Claimants should also be aware that if the injury is not considered a threshold injury, they may still access treatment and care benefits and weekly income payments under the CTP scheme, but they will not be able to claim damages for pain and suffering or loss of enjoyment of life. These damages are only available when the injury meets the threshold and the claimant has a WPI of at least 10%.
When to Seek Independent Legal Advice
The assessment of psychiatric injury eligibility involves complex medical and legal standards. The decision on whether an injury qualifies as a threshold injury is not made solely by the claimant or treating doctor. It is determined by an independent medical assessor under the MAIA and may be subject to review or dispute.
If a claim is rejected on the grounds that the injury does not meet the threshold, or if the WPI assessment is disputed, the claimant may seek a review or apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination. Given the high evidentiary burden and the potential for a claim to be denied on technical grounds, independent legal advice is recommended before finalising any claim.
Hypothetical Example: A Claim in Greater Sydney
A 38-year-old office worker in Sydney’s inner west was involved in a rear-end collision on a busy road in the Eastern Suburbs. The impact caused her to experience acute panic attacks and insomnia. Over the following months, she was diagnosed with PTSD by a psychologist and underwent cognitive behavioural therapy and medication. After 18 months, a WPI assessment confirmed a 15% permanent impairment due to the psychological injury. Because the injury met the threshold and was not minor, she was eligible to claim damages for pain and suffering under the CTP scheme.
