Common Causes of Treatment Provider Disputes in NSW CTP Claims

Disputes between CTP claimants and treatment providers in New South Wales typically arise when an insurer refuses to fund a recommended treatment, limits the number of sessions, or disputes the medical necessity of a service. These disagreements often occur when a treatment provider submits a claim for services that the insurer deems not covered under the Motor Accident Injuries Act 2017, or when the insurer caps the treatment duration below what the provider considers clinically appropriate. Common grounds for dispute include the type of treatment (such as physiotherapy, psychological counselling, or chiropractic care), the provider’s qualifications, and whether the treatment is directly related to injuries sustained in a motor accident. The dispute may also stem from a disagreement over whether the treatment is reasonable and necessary, a requirement under the CTP scheme.

How SIRA Manages Disputes Between Claimants and Treatment Providers

The State Insurance Regulatory Authority (SIRA) is the independent body responsible for overseeing the CTP scheme in NSW. SIRA does not directly resolve disputes between claimants and treatment providers. Instead, it provides a framework for dispute resolution and ensures that insurers and claimants follow the rules set out in the Motor Accident Injuries Act 2017 and the Motor Accident Injuries Regulation 2017. When a claimant disagrees with an insurer’s decision to deny or limit treatment, they may request an internal review from the insurer. If the internal review does not resolve the issue, the claimant may apply to SIRA for a determination. SIRA will assess whether the insurer’s decision was reasonable and in line with the law, including whether the treatment was medically necessary and appropriate for the claimant’s injuries.

Dispute Resolution Options for CTP Treatment Provider Conflicts

There are several formal and informal pathways available to resolve disputes over treatment funding in NSW CTP claims. The first step is to request an internal review from the insurer. Insurers are required to provide a written response within 21 days of receiving a review request. If the insurer upholds its original decision, the claimant may apply to SIRA for a determination. SIRA will assess the medical evidence and determine whether the insurer’s decision was reasonable. The claimant may also seek mediation through the Personal Injury Commission (PIC), which offers a free, confidential process to help parties reach an agreement without going to court. Mediation is voluntary and may be used at any stage of the claim process. In some cases, a claimant may choose to seek a medical assessment from an independent practitioner to support their case, particularly if the insurer disputes the diagnosis or treatment plan.

Practical Steps and Evidence That Usually Matter

To strengthen a dispute resolution application, claimants should gather and preserve the following evidence: a written treatment plan from the provider outlining the recommended treatment and its medical basis; a record of all communications with the insurer, including emails and letters; a copy of the insurer’s decision letter; and any medical reports, diagnostic imaging, or progress notes that support the need for treatment. Photographs of the accident scene, witness statements, and a detailed diary of symptoms and treatment outcomes may also be helpful. It is important to keep all documentation in a single folder and to notify the insurer in writing of any change in treatment plan or provider. Failure to provide timely and complete evidence may delay or reduce the chance of a favourable outcome.

Time Limits and the Importance of Early Action

There is no fixed statutory deadline for challenging a decision on treatment funding, but delays may affect the ability to obtain a determination. It is advisable to initiate the dispute process as soon as an insurer denies or limits treatment. The insurer must respond to a review request within 21 days, and SIRA may take up to 60 days to issue a determination. If a claimant is dissatisfied with a SIRA determination, they may apply to the NSW Civil and Administrative Tribunal (NCAT) for a review. However, the claimant must apply to NCAT within 28 days of receiving the SIRA determination. The Personal Injury Commission also offers a medical dispute pathway for cases involving conflicting medical opinions, which may be used if the insurer disputes the medical evidence. A claimant should not assume that a challenge will result in a change of decision; the outcome depends on the strength of the evidence and whether the insurer’s decision was reasonable under the law.

Hypothetical Example: A Dispute Over Psychological Treatment

A 34-year-old woman was involved in a rear-end collision in Sydney in June 2024. She developed anxiety and sleep disturbances following the accident. Her psychologist submitted a treatment plan for 12 sessions of cognitive behavioural therapy (CBT). The insurer approved only six sessions, citing that the condition was not severe enough to warrant ongoing treatment. The claimant requested an internal review, which was denied. She then applied to SIRA for a determination and submitted a medical report from her psychologist, a sleep diary, and a record of her symptoms. SIRA reviewed the evidence and found that the insurer’s decision was not reasonable given the clinical evidence. It directed the insurer to fund the full course of 12 sessions. This example illustrates how medical evidence and timely application can influence the outcome of a treatment provider dispute.

When to Seek Independent Advice

Disputes over treatment funding can be complex and emotionally taxing. While the CTP scheme provides access to medical treatment, the process of challenging a decision can be difficult to navigate without support. It is advisable to seek independent advice from a legal practitioner or a claims assessor who understands the CTP scheme and SIRA’s dispute resolution processes. A qualified professional can help assess the strength of the evidence, prepare the application, and represent the claimant in mediation or tribunal proceedings. However, no advice should be given on whether a claim will succeed, as every claim depends on its own facts and evidence.
