Understanding CTP Treatment Provider Disputes in NSW
If your CTP insurer has declined or limited treatment recommended by your medical practitioner, you may have a dispute under the Motor Accident Injuries Act 2017. This situation commonly arises when an insurer refuses to fund a treatment such as physiotherapy, psychological counselling, or specialist consultations, or caps the number of sessions. In Bankstown, NSW, and across the state, injured persons have formal dispute resolution options under the SIRA (State Insurance Regulatory Authority) framework. These options are designed to resolve disagreements between claimants and CTP insurers regarding treatment eligibility, duration, or type, without immediate court involvement.
The Legal Framework for Treatment Disputes
Under the Motor Accident Injuries Act 2017, CTP insurers are required to provide treatment and care benefits for injuries arising from a motor accident. These benefits cover medical treatment, allied health services, and rehabilitation. However, insurers may dispute the necessity, appropriateness, or cost of a treatment. The law does not require insurers to accept every treatment recommendation, but they must provide a reasonable basis for any refusal or limitation.
When a dispute arises, the claimant may seek resolution through SIRA’s dispute resolution processes. These include internal review, mediation, and, if necessary, an application to the Personal Injury Commission. The process is not automatic, each step requires a formal request and adherence to time limits.
Steps to Resolve a CTP Treatment Dispute in Bankstown
The first step is to formally request an internal review from the CTP insurer. This must be done in writing and within 28 days of receiving the insurer’s decision. The insurer must respond within 21 days, providing a written explanation of their decision. If the insurer upholds the original decision, you may proceed to the next stage.
The next option is mediation through SIRA. Mediation is a voluntary process where a neutral third party facilitates discussion between you, your treatment provider, and the insurer. It is not binding, but it often leads to a resolution without further formal proceedings. Mediation is available for disputes involving treatment, care, and support services.
If mediation is not successful, or if the dispute involves a formal determination about the nature or extent of treatment, you may apply to the Personal Injury Commission. This is a formal process where a tribunal member reviews the evidence and makes a binding decision. You must file your application within 12 months of the insurer’s initial decision, or within 12 months of the internal review outcome, whichever is later.
Evidence That Matters in a Treatment Dispute
To support your case, you must gather and preserve the following evidence:
- A written treatment plan from your medical practitioner, including diagnosis, recommended treatment, and expected duration.
- Correspondence from your treatment provider outlining the treatment and its medical necessity.
- A copy of the insurer’s written decision declining or limiting treatment.
- Medical records showing the progression of your injury and response to treatment.
- Photographs of the accident scene, if relevant to the injury.
- Witness statements, if available.
A medical report from an independent specialist may be necessary if the insurer disputes the diagnosis or treatment need. The Motor Accident Guidelines require that treatment must be clinically appropriate and not excessive. The burden of proof lies with the claimant to demonstrate that the treatment is reasonable and necessary.
When to Seek Legal Advice
A dispute over treatment does not automatically require legal representation, but it is advisable to seek legal advice if:
- The insurer has refused treatment that is supported by a specialist report.
- The treatment is being capped or limited without a clear rationale.
- You have been denied treatment for a condition that affects your ability to return to work or daily functioning.
- The insurer has not responded to your internal review request within the required timeframe.
Legal advice can help you assess whether the insurer’s decision is reasonable under the Motor Accident Injuries Act 2017 and the Motor Accident Guidelines. It can also assist in preparing a formal application to the Personal Injury Commission, if required.
Hypothetical Example: A Dispute in Bankstown
A 38-year-old Bankstown resident was involved in a rear-end collision in a car park in June 2025. The claimant developed chronic neck pain and was referred to a physiotherapist and a psychologist. The CTP insurer approved 12 sessions of physiotherapy but refused approval for further sessions or psychological treatment, citing a lack of evidence for ongoing mental health impact. The claimant submitted a report from their treating psychologist confirming a diagnosis of adjustment disorder with anxiety, and a physiotherapist report stating that continued treatment was clinically necessary. The claimant requested an internal review, which was denied. They then applied for mediation through SIRA, which resulted in a resolution where the insurer agreed to fund 20 additional physiotherapy sessions and 10 psychological sessions.
Time Limits and Procedural Requirements
Time limits are critical. The internal review must be requested within 28 days of receiving the insurer’s decision. The application to the Personal Injury Commission must be made within 12 months of the insurer’s original decision or the internal review outcome, whichever is later. Missing these deadlines may prevent you from pursuing formal dispute resolution.
A challenge to a decision does not guarantee a change in outcome. The insurer may still maintain its position, and a tribunal may uphold the original decision. However, the process ensures that decisions are made on the basis of evidence, not arbitrary discretion.
