Physiotherapy Approval, Common Mistakes to Avoid in NSW CTP Claims (Greater Sydney)

This article explains common mistakes to avoid when seeking physiotherapy treatment approval under NSW CTP laws, including starting treatment without approval, incomplete medical reports, and ignoring time limits. It outlines practical steps to secure approval and when to seek legal advice.

Current as at 25 October 2026

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).

If you're seeking physiotherapy treatment approval under NSW Compulsory Third Party (CTP) laws, avoiding common mistakes is critical. The CTP regime governs claims for injuries caused by motor vehicle accidents, and physiotherapy is a statutory benefit available to eligible claimants. However, many people in Greater Sydney fail to secure approval due to errors in documentation, communication with insurers, or misunderstanding the legal process. This article explains the key rules, practical steps to avoid pitfalls, and when to seek legal guidance.

The NSW CTP Rules Behind Physiotherapy Approval

Under the Motor Accident Injuries Act 2017, physiotherapy treatment is a statutory benefit available to claimants with threshold injuries. Threshold injuries are defined as injuries that meet specific medical criteria, such as a spinal nerve-root injury producing neurological signs. To qualify for physiotherapy, your injury must be classified as a threshold injury by a medical practitioner.

Insurers must approve treatment before it can be claimed. This means you cannot start physiotherapy without first obtaining written confirmation from the insurer. SIRA (State Insurance Regulatory Authority) outlines that claimants must submit a detailed medical report from their treating doctor to support the request. Failure to follow this process can result in the insurer denying the claim.

Common Mistakes to Avoid

  1. Starting Treatment Without Approval: One of the most frequent errors is beginning physiotherapy before the insurer has approved it. Under NSW CTP rules, treatment must be pre-approved. Starting treatment without approval may mean you cannot claim the costs.
  1. Incomplete or Poorly Documented Medical Reports: Insurers require detailed reports that clearly link the injury to the accident. Reports that lack specific clinical findings, such as neurological signs or imaging results, may be rejected. For example, a report stating 'the patient has a back injury' without specifying the type or severity may not meet the threshold injury criteria.
  1. Not Following the Insurer’s Process: Each insurer has its own procedures for approving treatment. Some may require a specific form, while others ask for a referral from a specialist. Failing to adhere to these steps can delay or block approval.
  1. Ignoring Time Limits: The CTP regime has strict deadlines. For instance, you must notify the insurer of your injury within a reasonable time, typically within a few weeks of the accident. Delays can jeopardize your ability to claim treatment costs.

Practical Steps to Secure Approval

To avoid these mistakes, take the following steps:

  • Obtain a Detailed Medical Report: Ensure your doctor includes specific clinical findings, such as neurological signs, imaging results, and a diagnosis of a threshold injury. Avoid vague descriptions.
  • Submit the Report to the Insurer: Send the report to the insurer promptly. Keep a copy for your records and follow up if you don’t receive a response within a reasonable time.
  • Follow the Insurer’s Instructions: If the insurer requests additional information or a specialist referral, comply with their requirements. This may include a second opinion from a specialist.
  • Seek Legal Advice if Needed: If the insurer denies your claim without a valid reason, consult a legal professional. They can help you challenge the decision or explore other options.

Time Limits and Dispute Options

The CTP regime has time limits for claims. For example, you must notify the insurer of your injury within a reasonable time, usually a few weeks. If you fail to meet these deadlines, you may lose the right to claim treatment costs. Disputes over approval decisions can be escalated to the NSW Civil and Administrative Tribunal (NCAT), but this is a last resort. Most insurers resolve disputes through internal processes.

When to Seek Advice

If you’re unsure whether your injury qualifies for physiotherapy, or if the insurer has denied your claim, it’s wise to seek legal advice. A solicitor can review your medical reports, assess the insurer’s decision, and help you navigate the process.

Conclusion

Securing physiotherapy approval under NSW CTP laws requires careful attention to documentation, communication with insurers, and adherence to legal deadlines. Avoid common mistakes such as starting treatment without approval or submitting incomplete reports. If you’re facing challenges with your claim, contact a legal professional for guidance. Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
