How SIRA Assesses Treatment and Rehabilitation Plans 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).

Under New South Wales law, the State Insurance Regulatory Authority (SIRA) oversees the assessment of treatment and rehabilitation plans for motor accident claims. When a claimant seeks compensation for injuries, SIRA evaluates whether the proposed medical treatment and rehabilitation aligns with accepted clinical guidelines and the nature of the injury. This article explains the factors SIRA considers, the evidence required to support claims, and practical steps for claimants in Auburn.

What SIRA Looks For in Treatment Plans

SIRA assesses treatment and rehabilitation plans based on the Motor Accident Guidelines, which outline the standards for medical care following a motor accident. Key factors include:

  • Medical necessity: Whether the treatment is clinically required to address the injury.
  • Alignment with guidelines: Whether the treatment plan follows evidence-based practices.
  • Rehabilitation goals: Whether the plan includes measurable objectives to restore function or reduce long-term disability.
  • Documentation: Whether medical records and treatment plans clearly support the proposed care.

For example, if a claimant requires physiotherapy to recover from a soft-tissue injury, SIRA will review the therapist’s plan to ensure it addresses the specific injury and follows the guidelines.

Evidence to Support Rehabilitation Planning

To strengthen a claim, injured claimants should gather:

  • Medical records detailing the injury and treatment recommendations
  • A detailed treatment plan from a medical practitioner
  • Rehabilitation goals outlined in the plan
  • Evidence of how the injury impacts daily activities or work capacity
  • Correspondence with insurers or SIRA regarding treatment approvals

These documents help demonstrate that the treatment is both necessary and proportionate to the injury.

Time Limits and Dispute Options

Under the Motor Accident Injuries Act 2017, claims must typically be submitted within 52 weeks of the accident if the injury is classified as a 'threshold injury' (a soft-tissue injury meeting specific clinical criteria). If a claimant’s injury exceeds the threshold, they may be eligible for ongoing weekly benefits and treatment costs.

If a claimant disagrees with SIRA’s assessment, they can request a review or seek independent medical opinions. However, disputes must be resolved within strict timeframes to avoid procedural dismissal.

When to Seek Legal Advice

Claimants should consult a legal professional if:

  • Their treatment plan is rejected by SIRA
  • They face pressure to settle for less than the claimed value
  • They need help navigating the claims process

A solicitor can help challenge SIRA’s decision or negotiate a fair settlement based on the evidence.

Example: A Claimant’s Treatment Plan

Consider a claimant who suffered a whiplash injury in a car accident. Their doctor recommends six weeks of physiotherapy to restore mobility. SIRA will evaluate whether the treatment plan:

  • Is supported by clinical evidence
  • Aligns with the Motor Accident Guidelines
  • Addresses the claimant’s specific symptoms

If the plan meets these criteria, the claimant is likely to receive approval for the treatment costs.
