What Changed to Psychiatric Injury Assessments After 2017?

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).

The 2017 reforms to NSW’s Compulsory Third Party (CTP) scheme introduced significant changes to how psychiatric injuries are assessed under the Motor Accident Injuries Act 2017 (MAIA). Previously, psychological injuries were classified under the broad 'minor injury' threshold, but the reforms shifted to a more structured framework based on clinical evidence. Under the new rules, psychiatric injuries must now meet specific criteria outlined in the Motor Accident Guidelines, including measurable neurological signs or clinical indicators of trauma. This change impacts claims for anxiety, depression, or post-traumatic stress disorder (PTSD) arising from motor accidents.

How SIRA Assesses Psychiatric Injuries in Illawarra and South Coast

SIRA, the regulator for NSW CTP claims, now evaluates psychiatric injuries using a two-part test:

  • Threshold injury: The injury must meet the definition of a 'threshold injury' under the MAIA, which includes psychological injuries that result in a clinically diagnosable condition.
  • Clinical evidence: Medical records must demonstrate a direct link between the accident and the psychiatric injury, such as a diagnosis of PTSD or major depressive disorder.

In the Illawarra and South Coast regions, SIRA offices apply these guidelines uniformly, though local practitioners may interpret clinical signs differently. Claimants should ensure their medical records include detailed documentation of symptoms, treatment plans, and a clear connection to the accident.

Practical Steps for Claiming Psychiatric Injury Compensation

To meet the new psychiatric injury threshold, claimants should:

  • Seek immediate medical attention: Document the injury with a mental health professional, ideally one familiar with trauma-related conditions.
  • Preserve evidence: Keep records of all medical appointments, therapy notes, and any correspondence with SIRA or insurers.
  • Understand time limits: Claims must be submitted within 52 weeks of the accident for treatment and care benefits. If the injury is not a 'threshold injury, ' benefits may be limited after this period.

Disputes over psychiatric injury claims are resolved through SIRA’s review process, which may involve independent medical assessments. Claimants should avoid downplaying their symptoms, as this could affect eligibility.

Example: How a Psychiatric Injury Claim Might Proceed

A driver involved in a collision on the South Coast experiences anxiety and flashbacks. Their GP documents symptoms consistent with PTSD and links them to the accident. Under the new rules, the claimant must demonstrate that the injury meets the 'threshold injury' definition, which requires clinical evidence of a diagnosable condition. If SIRA disputes the claim, the claimant may need to provide additional records or seek a second opinion from a specialist.

When to Seek Legal Advice

The 2017 reforms have narrowed the scope of psychiatric injury claims, making it essential to act quickly. If your claim is denied or you’re unsure whether your injury meets the threshold, contact a legal professional.
