What does reasonable and necessary treatment and care mean in a NSW CTP claim?

The insurer should examine the diagnosed accident injury, current symptoms and function, the treatment goal, accepted clinical practice, expected benefit, alternatives, frequency, duration and cost. A request is stronger where the treating practitioner explains what problem is being treated, why this intervention is suitable now, how progress will be measured and what will happen if it is not provided. A quotation alone does not answer those questions.

Causation and necessity are separate ideas. Treatment may be clinically sensible for a condition but not payable under the CTP claim if the insurer establishes that the condition is unrelated to the crash. Conversely, the fact that an injury was caused by the accident does not make every proposed treatment reasonable. Pre-existing disease, another accident or a change in diagnosis may require a careful medical explanation rather than a blanket acceptance or refusal.

The insurer may approve only part of a request, such as a shorter initial program with a review point. That is not necessarily unlawful, but the reasons should identify the approved scope and the evidence required for continuation. Outcome measures should be relevant to function and recovery, not used as a mechanical rule that treatment must stop after an arbitrary number of sessions.

A useful request identifies the accident-related diagnosis, clinical findings, prior treatment, response to treatment, functional limits and the precise service sought. It should state provider, frequency, duration, cost and measurable goals. Where surgery, equipment, home modification or long-term care is proposed, specialist reports, imaging, quotations and an occupational or functional assessment may be needed.

The insurer should not be asked to infer the rationale from a large medical file. A short treating report can connect the request to the evidence and answer the insurer’s earlier concerns. If treatment has already begun, keep attendance records, invoices, receipts and notes showing benefit, adverse effects or reasons for changing the plan. Evidence that a person still has pain is important but may not, without more, establish why the particular treatment remains necessary.

Travel and accommodation associated with treatment can also be payable where reasonable and necessary. The Act specifically addresses some parent or carer travel where the injured person is under 18 or needs assistance to travel. Record the appointment, distance, transport used, reason assistance was required and actual expense rather than presenting an unsupported estimate.

Guidelines clause 4.106 requires the insurer to decide a treatment and care request as soon as possible and no later than 10 days after receiving it. A refusal should give reasons, identify the evidence relied on and explain internal review and PIC options. If more information is needed, ask precisely what is missing and whether the insurer will reconsider once it is supplied.

A dispute about whether treatment is reasonable and necessary or related to the accident is a medical assessment matter under Schedule 2 of the Act. A dispute about whether the amount charged is reasonable is a merit review matter. One letter can contain both issues, so the response should separate clinical necessity from price rather than lodging an unfocused objection.

Internal review is commonly relevant before a PIC application, but the correct process and time depend on the decision. Read the review section of the actual notice. A complaint about delay or poor communication may help address service, but it does not replace the statutory review or medical-dispute process and does not extend a deadline.
