How NSW CTP Insurers Approve Physiotherapy Treatment Costs

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).

Under New South Wales law, physiotherapy treatment costs for motor accident injuries are funded through the Compulsory Third Party (CTP) scheme. Insurers assess whether treatment is approved based on medical evidence, the nature of the injury, and SIRA guidelines. This article explains the legal process, required documentation, and common reasons claims are approved or rejected.

Legal Framework for CTP Physiotherapy Funding

The Motor Accident Injuries Act 2017 (MAIA) governs CTP claims in NSW. SIRA (State Insurance Regulatory Authority) provides authoritative guidance on what treatment is funded. Key principles include:

  • Medical necessity: Treatment must be clinically necessary to address the injury caused by the accident.
  • SIRA guidelines: The Motor Accident Guidelines (2023) outline criteria for approving treatment, including the type, frequency, and duration of physiotherapy.
  • Threshold injuries: If the injury is classified as a 'threshold injury' (e.g., soft tissue damage), treatment costs are generally limited to 52 weeks under the MAIA.

Insurers must approve treatment before it is provided. This is distinct from common law damages claims, which are separate legal pathways.

Evidence Required for Approval

To secure funding, claimants must provide:

  • Medical reports: A doctor must confirm the injury is directly related to the accident. For example, a physiotherapist’s report must link treatment to the accident.
  • Treatment plan: A detailed plan outlining the type of therapy (e.g., exercises, manual therapy) and its expected benefits.
  • Clinical records: Evidence of the injury’s severity, such as imaging or neurological signs, to justify the treatment.
  • SIRA compliance: The treatment must align with SIRA’s guidelines. For instance, repetitive exercises for a sprained ankle may be approved, but prolonged sessions for a minor strain may not.

Common Reasons for Rejection

CTP insurers often reject claims for:

  • Lack of medical evidence: Without a clear link between the treatment and the accident, insurers may deny funding.
  • Exceeding 52 weeks: If the injury is a threshold injury, treatment beyond 52 weeks is generally not funded unless it’s for a specific, documented need.
  • Non-compliance with SIRA guidelines: Treatment not aligned with SIRA’s approved protocols may be rejected.

Example: Approved vs. Rejected Claims

  • Approved: A cyclist with a fractured wrist receives 12 weeks of physiotherapy to regain mobility, as confirmed by a medical report and SIRA guidelines.
  • Rejected: A pedestrian with a minor bruise requests 6 months of physiotherapy for 'pain management' without evidence of a diagnosed injury. Insurers may reject this as non-essential.

Time Limits and Dispute Options

CTP claims must be submitted within 52 weeks of the accident for certain benefits. If treatment is approved, it is typically funded for up to 52 weeks unless the injury is classified as a whole-person impairment. Disputes over funding decisions can be escalated to SIRA for review.

When to Seek Legal Advice

If your physiotherapy treatment is denied, or if you’re unsure whether it meets SIRA’s criteria, it’s important to consult a legal professional. They can help ensure your claim aligns with the MAIA and SIRA guidelines.
