Psychiatric Injury Threshold in NSW CTP Claims

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

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).

Under New South Wales law, psychiatric injuries claimed under the Compulsory Third Party (CTP) scheme must meet specific criteria to qualify for compensation. The Motor Accident Guidelines define 'threshold injury' as a condition that results in a significant and lasting impact on a person's daily life. For psychiatric injuries, this typically requires evidence of a diagnosable condition such as post-traumatic stress disorder (PTSD), depression, or anxiety that meets clinical thresholds. SIRA (State Insurance Regulatory Authority) provides detailed guidance on assessing whether a psychiatric injury qualifies under the CTP scheme.

Common Mistakes in Psychiatric Injury Claims

Claimants in Illawarra and South Coast often make errors that reduce their chances of securing compensation. One frequent mistake is failing to establish a clear link between the accident and the psychiatric injury. For example, a claimant may not provide sufficient medical evidence showing that their symptoms began after the incident. Another common error is not documenting the injury's impact on daily activities, such as work, family life, or personal care. SIRA emphasizes that claims must demonstrate how the injury affects the person's ability to function normally.

A third mistake is underestimating the importance of seeking professional medical advice promptly. Delayed treatment or failure to follow up with healthcare providers can weaken a claim. Additionally, some claimants overlook the need to report the injury to their insurer within the required timeframe, which can lead to disputes over eligibility.

How to Avoid Errors in CTP Claims

To avoid these pitfalls, claimants should take specific steps. First, obtain a thorough medical assessment from a qualified mental health professional. This should include documentation of symptoms, diagnosis, and how the injury affects daily life. Second, keep detailed records of all medical appointments, treatment plans, and correspondence with healthcare providers. Third, report the psychiatric injury to the relevant insurer as soon as possible, ideally within 52 weeks of the accident. This timeframe is critical, as SIRA may limit benefits after this period if only threshold injuries are involved.

In Illawarra and South Coast, claimants should also consider consulting a solicitor familiar with local CTP practices. While legal advice is not mandatory, it can help ensure compliance with SIRA's requirements. For instance, a solicitor can assist in preparing a claim that clearly demonstrates the psychiatric injury meets the threshold criteria.

SIRA Guidance on Psychiatric Injury Claims

SIRA's guidelines stress that psychiatric injuries must be evaluated based on clinical evidence, not subjective claims. The Motor Accident Guidelines outline specific criteria for diagnosing and assessing the severity of mental health conditions. For example, a diagnosis of PTSD must include symptoms such as flashbacks, avoidance behaviors, and hyperarousal that persist for at least a month. Claimants should ensure their medical records include such details.

SIRA also advises that claims for psychiatric injuries should include evidence of how the injury impacts the person's quality of life. This could involve documentation of missed workdays, strained relationships, or difficulty performing routine tasks. Failure to provide this evidence may result in the claim being rejected or limited to statutory benefits only.

Practical Example

Consider a claimant who was involved in a car accident and later developed anxiety. If they only report occasional stress without seeking professional help, their claim may be dismissed as not meeting the threshold. However, if they undergo therapy, receive a diagnosis of generalized anxiety disorder, and document how the condition affects their ability to work, their claim is more likely to succeed.

Next Steps

CTP claims involving psychiatric injuries require careful attention to legal and medical details. Claimants in Illawarra and South Coast should ensure they meet SIRA's threshold requirements and avoid common errors.
