Treatment provider disputes in NSW CTP claims

If you're injured in a motor accident in NSW and disagree with your treatment provider's decisions, you're not alone. Disputes over treatment plans, denied sessions or capped therapy hours are common. Understanding your rights under the NSW Compulsory Third Party (CTP) scheme and how to resolve conflicts is essential. This article explains how SIRA regulates treatment provider disputes, what evidence matters and when to seek legal advice.

How NSW CTP rules apply to treatment provider disputes

Under the Motor Accident Injuries Act 2017, treatment providers must act in the injured person's best interests. SIRA oversees these interactions, ensuring providers follow the Motor Accident Guidelines. If a provider denies or limits treatment, you may need to:

  • Request a written explanation for the decision
  • Challenge the provider's clinical judgment using medical records
  • Seek a second opinion from a registered medical practitioner

SIRA's role is to mediate disputes, not to make clinical decisions. Providers must justify their treatment plans based on medical evidence, not financial constraints.

Practical steps and evidence to resolve disputes

When resolving a treatment provider dispute, focus on these key elements:

  • Medical records: Document all treatment plans, progress notes and clinical assessments. Providers must base decisions on objective medical evidence, not convenience.
  • Accident details: Show how the injury relates to the accident. SIRA may require a medical report linking the treatment to the accident's impact.
  • Communication records: Keep copies of all correspondence with the provider, including emails, letters and phone records.
  • Witness statements: If a treatment provider refuses to engage with your doctor, witness accounts of the refusal can support your case.

If a provider caps therapy sessions or denies treatment, you should request a formal review. SIRA may require a medical expert to assess whether the treatment plan aligns with the injury's severity.

Time limits and when to seek advice

The 52-week statutory benefit period under the Motor Accident Injuries Act 2017 applies to weekly income payments, but treatment disputes can extend beyond this. If a provider denies treatment after 52 weeks, you may need to:

  1. Submit a written request for review within 28 days of the decision
  2. Provide new medical evidence showing ongoing treatment needs
  3. Seek legal advice if the provider refuses to reconsider

The Personal Injury Commission (PIC) handles medical disputes under the Workers Compensation Act 1993, but CTP claims are governed by separate rules. If your treatment provider refuses to engage with your doctor, this could indicate a systemic issue requiring legal intervention.

Example of a treatment dispute

Consider a scenario where a provider denies a patient's request for physiotherapy after a whiplash injury. The provider claims the treatment is 'not clinically indicated' despite the patient's medical records showing persistent neck pain. In this case, the injured person should:

  • Request a detailed explanation of the provider's clinical reasoning
  • Obtain a second opinion from a specialist
  • File a formal dispute with SIRA

This example highlights how disputes often hinge on interpreting medical evidence. SIRA may require a medical expert to determine whether the treatment plan is reasonable.

When to seek independent legal advice

If a treatment provider refuses to engage with your medical team or denies treatment without justification, it may indicate a systemic issue. Legal advice is essential if:

  • You're facing financial hardship due to denied treatment
  • The provider refuses to provide a written explanation
  • You need to challenge a decision under the Motor Accident Injuries Act 2017

Legal professionals can help you navigate SIRA's dispute resolution process and ensure your rights under the CTP scheme are protected.
