How SIRA Handles Treatment Provider Disputes in NSW CTP Claims

If your treatment provider has been denied or capped funding under your NSW Compulsory Third Party (CTP) claim, SIRA’s guidelines determine how disputes are resolved. This article explains how SIRA interprets the rules, what steps to take, and how to challenge decisions in Greater Sydney.

Understanding the Legal Framework Behind Treatment Disputes

Under the Motor Accident Injuries Act 2017, insurers must fund treatment that is 'reasonably necessary' for your recovery. SIRA’s Making a Motor Accident Claim page clarifies that treatment must be:

  • Approved by a medical practitioner
  • Reasonably necessary to address your injury
  • Within the scope of the claim

Disputes often arise when insurers dispute the necessity of treatment, the provider’s qualifications, or the cost. SIRA’s What You Can Claim page states that claimants must provide evidence of the treatment’s relevance to your injury, such as medical records or a GP’s report.

Practical Steps to Resolve a Treatment Provider Dispute

  1. Document the Dispute: Keep records of all communication with the insurer, including emails, letters, and phone notes. Note any specific reasons the insurer gave for denying or limiting treatment.
  1. Request a Review: Under SIRA’s rules, you can ask the insurer to review their decision within 28 days of receiving the response. This must be done in writing and include your reasoning for disputing the decision.
  1. Seek Independent Medical Advice: If the insurer disputes the necessity of treatment, obtain a second opinion from a medical practitioner. This can help demonstrate that the treatment is still required.
  1. Involve the Personal Injury Commission (PIC): If the insurer refuses to review or disputes the treatment, you can escalate the matter to the PIC. The PIC can mediate disputes or refer the case to a medical expert for review.

Time Limits and When to Seek Advice

You have 28 days from the date of the insurer’s decision to request a review. If the insurer refuses to act, you must escalate the matter to the PIC within 60 days of the original decision. Delays beyond these deadlines may reduce your options for challenging the decision.

SIRA’s guidelines emphasize that disputes must be resolved through the insurer’s internal review process before escalating. If you’re unsure whether your case meets the criteria for a review, contact SIRA directly or seek advice from a legal professional.

How SIRA’s Interpretations Affect Funding

SIRA’s interpretation of 'reasonably necessary' treatment has a direct impact on funding. For example, if your treatment provider recommends a therapy that SIRA deems non-essential, the insurer may refuse to fund it. In such cases, you must provide additional evidence to justify the treatment’s relevance to your injury.

A practical example: If your GP recommends physiotherapy for a soft tissue injury, but the insurer disputes its necessity, you must provide evidence such as:

  • A detailed medical report explaining the injury’s nature
  • A statement from your GP confirming the therapy’s relevance
  • Records of your progress or worsening symptoms

When to Seek Legal Advice

If your dispute involves complex medical or financial issues, or if the insurer refuses to engage with your concerns, legal advice may be necessary. A solicitor can help you:

  • Navigate SIRA’s review process
  • Challenge decisions that may be legally flawed
  • Explore options for dispute resolution beyond the insurer’s internal process

Next Steps for Claimants

If you’re facing a treatment provider dispute, start by reviewing the insurer’s decision and requesting a review within 28 days. Document all evidence of your injury and the treatment’s necessity. If the insurer refuses to act, escalate the matter to the PIC or seek legal advice to ensure your rights are protected.
