How SIRA Approves Physiotherapy for NSW CTP Claims

SIRA approves physiotherapy treatments for NSW CTP claims based on medical necessity and alignment with the Motor Accident Guidelines.

How SIRA Approves Physiotherapy for 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).

If you're seeking physiotherapy treatment for a motor accident injury under NSW's Compulsory Third Party (CTP) scheme, you need to understand how the State Insurance Regulatory Authority (SIRA) determines approval. SIRA's guidelines outline what treatments are covered, how to request approval, and what happens if your application is denied. This article explains the rules in plain language.

What SIRA Considers for Physiotherapy Approval

SIRA evaluates physiotherapy treatments based on medical necessity and alignment with the Motor Accident Guidelines. To qualify, your treatment must:

  • Be prescribed by a medical practitioner
  • Be directly related to your injury from the accident
  • Be part of a documented treatment plan
  • Be reasonable in cost and duration

SIRA's guidelines emphasize that treatment must be 'medically necessary' and 'reasonably required' for recovery. For example, a physiotherapist must provide evidence that exercises will improve mobility or prevent complications from a soft tissue injury.

How to Request Approval for Physiotherapy

To get approval, you must submit:

  • A completed Physiotherapy Approval Request Form (available on SIRA's website)
  • A treatment plan from your physiotherapist
  • Medical records confirming your injury and treatment needs
  • Proof of your injury's connection to the accident (e.g., medical reports)

You must submit these documents to your insurer within 52 weeks of the accident. If your injury is classified as a 'threshold injury' (a soft tissue injury with minimal long-term impact), SIRA may limit treatment approval after 52 weeks under the Motor Accident Injuries Act 2017.

What Happens if Your Treatment is Denied

If SIRA denies your request, you can:

  1. Request a review by submitting additional evidence
  2. Appeal to the NSW Civil and Administrative Tribunal (NCAT) within 28 days of the denial

SIRA's decision must be based on the guidelines, but you can challenge it if you believe the assessment was incorrect. For example, if your physiotherapist provided evidence of a spinal nerve-root injury (as defined in the Motor Accident Guidelines), SIRA must consider that before denying approval.

Practical Steps to Take

To ensure your physiotherapy treatment is approved:

  • Get a clear diagnosis of your injury from a medical practitioner
  • Keep detailed records of all treatments and costs
  • Submit your request within the 52-week window for threshold injuries
  • Keep copies of all insurer correspondence

If you're unsure about your eligibility, contact SIRA directly. Their guidelines are publicly available, but navigating them can be complex without legal guidance.

When to Seek Legal Advice

SIRA's approval process can be confusing, especially if your injury involves complex medical conditions. A solicitor can help you:

  • Challenge a denial based on medical evidence
  • Navigate time limits for claims
  • Understand how your injury's severity affects treatment approval

Remember, SIRA's authority is limited to the Motor Accident Injuries Act 2017. If your injury overlaps with workers' compensation or other schemes, you may need to seek advice from a specialist in multiple areas of injury law.
