Common Mistakes in Treatment Provider Disputes

When insurers dispute the cost or necessity of approved treatment under NSW CTP claims, claimants often make errors that weaken their case. One frequent mistake is failing to document the treatment provider’s recommendations in writing. Without clear records, insurers may challenge the treatment’s relevance to the accident. Another error is not understanding the distinction between SIRA-approved treatment and private care, CTP benefits only cover treatment approved by SIRA.

Legal Framework for CTP Treatment Disputes

  • NSW CTP claims are governed by the Motor Accident Injuries Act 2017 (MAIA), which requires treatment to be 'reasonably necessary' and 'directly related' to the accident. SIRA’s
  • Motor Accident Claims* guidelines clarify that disputes over treatment must be resolved through the insurer’s internal review process, not the courts. Claimants must submit a written request for review within 28 days of the insurer’s decision, as outlined in SIRA’s
  • Making a Motor Accident Claim* page.

Practical Steps to Avoid Disputes

To prevent treatment disputes, claimants should:

  • Keep detailed records of all treatment communications with insurers
  • Obtain written confirmation of the treatment provider’s assessment
  • Understand that SIRA-approved treatment is limited to injuries from the accident
  • Avoid seeking private treatment without prior insurer approval

A common error is relying on a doctor’s note without verifying it against SIRA’s What You Can Claim guidelines. For example, a claimant who received physiotherapy for a back injury but failed to document how the treatment was linked to the accident may face a dispute.

Time Limits and When to Seek Advice

Insurers must respond to treatment disputes within 28 days of receiving a written request. If they refuse to approve treatment, claimants can escalate the matter to SIRA’s internal review process. However, delays in submitting disputes or failing to follow the correct procedure can result in lost benefits. Claimants should seek legal advice if their treatment is rejected or if they receive a notice of disagreement from the insurer.

SIRA’s Role in Resolving Disputes

SIRA oversees the CTP scheme and provides guidelines for resolving treatment disputes. Claimants should refer to the What You Can Claim page to confirm whether their treatment falls within the approved scope. While SIRA does not offer legal representation, its resources explain how to challenge a decision through the insurer’s review process. It’s important to note that disputes over treatment do not automatically entitle claimants to additional compensation, they must demonstrate the treatment was both necessary and directly related to the accident.

Next Steps for Claimants

If you’re facing a treatment dispute under NSW CTP laws, time and procedure matter. Always document your treatment, follow SIRA’s guidelines, and seek advice if your claim is challenged. Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
