Choosing or changing treatment providers
By Herman Chan, Stephen Young Lawyers | Published 2026-05-17 | Last reviewed 2026-06-12
Specific focus: this guide is about choosing and funding physiotherapists, psychologists, rehabilitation providers and specialists. It is not the same issue as changing your GP, disputing a treatment refusal, or claiming travel costs, which have their own evidence tests and next-step pages linked below.
Usually, you can ask to use your own treatment provider after a NSW motor accident, but CTP payment is not the same thing as personal preference. The insurer will usually focus on whether the treatment is reasonable and necessary, whether it relates to the injuries from the crash, whether the cost is properly supported, and whether the provider is giving useful information about your recovery. This is a practical evidence guide for choosing a CTP physio, psychologist, rehabilitation provider or specialist, not a guarantee that every session will be funded. General information only, not legal advice.
The short answer
A NSW CTP claimant is not usually forced to use a physiotherapist, psychologist, rehabilitation provider, or specialist chosen by the insurer for ordinary treating care. In practice, however, the insurer may decide whether it will fund the treatment under the statutory benefits scheme. That is why choosing a provider should be handled with evidence, not just a booking confirmation.
The safest approach is to keep your GP involved, use appropriately qualified providers, ask for written approval where treatment will be ongoing or costly, and make sure the provider explains how the treatment relates to the motor accident injury. If the insurer does not have that information, a payment dispute can develop even where the treatment feels obviously helpful to you. Keep any certificate of capacity consistent with the treatment plan, because treatment disputes can sometimes overlap with weekly payments, work capacity and insurer review decisions.
This page is about choosing allied health and specialist treatment providers. If your question is specifically about changing your GP, see the separate guide to changing GP or doctor during a CTP claim.
The practical evidence question is narrow: can the proposed provider show accident-related need, a sensible plan, measurable goals and progress review? If the dispute is already a refusal decision, use this page to organise the treatment evidence, then move to the treatment-refusal, Internal Review or PIC pathway rather than arguing provider preference in the abstract.
Provider choice approval map
Use this map before booking repeated or costly treatment. It keeps the provider-choice question separate from the insurer-funding question.
1. Referral
GP or specialist names the injury, provider type, and accident connection.
2. Plan
Provider gives frequency, cost, goals, review date, and reporting pathway.
3. Approval
Insurer checks whether treatment is reasonable, necessary, and crash-related.
4. Review
Progress notes show benefit, barriers, or why a provider change is justified.
The official source basis, in plain English
The Motor Accident Injuries Act 2017 (NSW), including section 3.24, is the main statutory benefits source for treatment and care. The key practical limits are that treatment and care must be reasonable and necessary in the circumstances and must relate to the injury resulting from the motor accident. That is why the issue is often framed as treatment need, causation, cost, and evidence.
Current SIRA CTP material for allied health practitioners also uses the reasonable and necessary treatment framework. SIRA guidance describes allied health practitioners such as physiotherapists and psychologists working with the injured person’s support team, including the doctor, insurer, rehabilitation provider, and others involved in treatment, care and support.
SIRA’s Motor Accident Guidelines include insurer obligations around treatment, rehabilitation and attendant care requests. The Guidelines are important because provider choice disputes are often really about whether the insurer has enough information to approve a treatment request, not about whether you are allowed to prefer one clinician over another.
SIRA’s rehabilitation-provider FAQ also states that CTP insurers are only obliged to pay for treatment, rehabilitation, attendant care or equipment that is considered reasonable and necessary, and that providers should have insurer approval before treatment where liability or funding is not clear. For a claimant, the practical message is to keep the rehabilitation plan, approval request and progress evidence aligned.
Source review note: reviewed 20 May 2026 against the Motor Accident Injuries Act 2017 (NSW), SIRA allied-health and rehabilitation-provider material, SIRA Motor Accident Guidelines, and PIC medical-dispute guidance about whether treatment or care is reasonable and necessary and relates to the motor accident injury. This page gives general information only and does not replace advice about your claim facts, insurer correspondence, treatment records or limitation dates.
How this page differs from nearby treatment guides
This provider-choice guide
Focuses on selecting or changing a physio, psychologist, rehab provider or specialist, and giving the insurer enough material to assess funding.
Changing GP or doctor
Focuses on continuity of certificates, clinical records, work-capacity evidence and avoiding gaps when your main doctor changes.
Treatment refused
Focuses on a written insurer refusal and the evidence or review pathway needed to challenge the reason actually given.
What makes a provider choice easier to justify?
A good provider choice is usually easy to explain. It connects with the diagnosed injury, fits the treatment plan, has a clear purpose, and can be reviewed after a sensible period. The insurer should be able to see what is being treated, why that treatment is needed, how often it will occur, what it is expected to achieve, and when progress will be reviewed.
Helpful reasons to choose a provider
- the provider has experience treating your type of injury
- the clinic is close enough for regular attendance
- the provider can communicate with your GP and insurer
- the provider offers language, cultural, or trauma-informed support
- the treatment goals are measurable and linked to function
- the provider can report progress and barriers promptly
Red flags for insurer pushback
- no referral, diagnosis, or treatment plan
- treatment continuing for months without progress notes
- high cost or long travel distance with no explanation
- unclear link between the treatment and crash injuries
- multiple providers doing overlapping treatment
- the provider does not answer insurer information requests
When should you ask for insurer approval?
If treatment is urgent, you should follow medical advice. For CTP reimbursement, though, written approval is often the safest practical step before repeated sessions, specialist consultations, psychological treatment, expensive scans, rehabilitation programs, surgery-related treatment, or anything involving significant travel.
Approval requests should be specific. A request that only says “please approve physiotherapy” is weaker than a request that includes the diagnosis, accident connection, current symptoms, functional limits, proposed treatment, number of sessions, cost, goals, and review date. If the request is for psychology, it should also explain the accident-related psychological symptoms being treated without overstating a diagnosis that has not been made.
If travel costs are involved, deal with that early too. A provider may be clinically suitable but far away. The further or more expensive the travel, the more important it is to explain why a closer provider is not appropriate. See the guide to travel expenses in NSW CTP claims.
Can the insurer make you see another doctor or assessor?
Sometimes the insurer may arrange an examination, ask for a rehabilitation assessment, seek a treatment review, or request information from your treating providers. That does not necessarily mean your own provider is rejected. It may mean the insurer is gathering evidence about causation, capacity, treatment need, or whether ongoing treatment remains reasonable and necessary.
Keep a distinction between your treating team and insurer-arranged assessments. Your treating physiotherapist, psychologist, specialist, or rehabilitation provider helps with treatment and recovery. An insurer-arranged examination may be used to make a claim decision. If an insurer-arranged report is later used to refuse treatment or reduce benefits, ask for the decision and reasons in writing and consider the relevant review pathway.
For more on assessments that can affect treatment or benefits, read the guide to independent medical examinations in NSW CTP claims.
Changing rehabilitation provider during the claim
Changing a rehabilitation provider can be reasonable. Common reasons include slow progress, poor communication, distance, availability, language needs, trauma comfort, a different injury focus, or a recommendation from your GP or specialist. The problem is not the change itself. The problem is a change that looks unexplained, duplicates treatment, or creates a gap in the evidence.
Before changing, ask for your records or a short transfer summary where possible. Then give the new provider the accident history, current symptoms, previous treatment, certificates, scans, and insurer details. If the new provider is asking for funding, the first report should explain what has changed, what will be done differently, and how progress will be measured.
Claimant handover checklist
- the reason the current rehabilitation plan is not working or is no longer practical
- a GP, specialist, or treating-provider note supporting the change where available
- a discharge, transfer, or progress summary from the current provider if it can be obtained
- the new provider’s role, qualifications, treatment goals, cost, frequency, and review date
- whether any treatment overlaps with existing physio, psychology, occupational therapy, or specialist care
- the written insurer approval request, especially if the change adds cost, travel, or a new discipline
Evidence to send with a provider approval request
| Evidence | Why it helps |
|---|---|
| GP or specialist referral | Shows clinical support and connects treatment to diagnosed injuries. |
| Treatment plan and goals | Shows what is proposed, how often, for how long, and what function should improve. |
| Cost estimate or provider rates | Helps the insurer assess reasonableness and avoids later invoice disputes. |
| Progress notes or outcome measures | Shows whether treatment is helping or whether the plan needs review. |
| Explanation for provider change | Reduces suspicion that treatment is duplicated, excessive, or unrelated. |
What a focused approval request should say
A useful approval request should not simply ask the insurer to “approve treatment”. It should identify the proposed provider, the injury being treated, the accident connection, the number and frequency of sessions, the expected cost, the functional goal and the review point. That makes the insurer’s decision easier to audit and reduces the risk that provider choice is confused with an unsupported funding request.
Plain-English request structure
- name the physiotherapist, psychologist, rehabilitation provider or specialist and their role in the recovery plan
- state the crash-related diagnosis or symptoms the treatment is addressing
- attach the referral, treatment plan, session estimate, costs and proposed review date
- explain the functional goal, such as walking tolerance, return-to-work capacity, sleep, driving confidence or daily activity
- ask for the decision and reasons in writing if the insurer does not approve the request
Compliance note: this is a practical evidence checklist, not a guarantee of payment. The insurer still has to assess the statutory treatment-and-care criteria and the facts of the individual CTP claim.
What if the insurer refuses to pay?
Do not guess at the reason. Ask for the decision in writing and identify whether the insurer disputes accident causation, clinical need, cost, frequency, provider qualifications, lack of progress, late approval, or missing records. Each problem needs a different response.
If the refusal is about treatment being reasonable and necessary, a focused medical report may help more than a long complaint email. If the refusal is about missing records, send the records in an organised bundle. If the refusal is about a legal or medical dispute pathway, check whether internal review or a Personal Injury Commission application is the correct next step.
You can read more in the guide to treatment refused in a NSW CTP claim or contact a NSW CTP lawyer if the decision affects treatment, weekly payments, or settlement strategy.
Useful next steps
- Ask your GP which provider type is clinically appropriate and why.
- Choose a provider who can give clear reports, not just appointments.
- Send the insurer a treatment plan before costs become large.
- Keep attendance records, invoices, travel records, and progress updates.
- Review progress after the approved block of sessions.
- If the insurer refuses payment, respond to the exact written reason.
FAQs about choosing treatment providers in NSW CTP claims
Can I choose my own physiotherapist or psychologist after a NSW crash?
Usually you can ask to use your own treating provider, but CTP payment is not automatic. The insurer will usually look at whether the treatment is reasonable and necessary, related to the motor accident injury, properly requested, and supported by clinical information.
Do I need insurer approval before starting treatment?
Approval depends on the treatment, timing, claim status, and insurer decision. For repeated, expensive, specialist, psychological, or rehabilitation treatment, the safer practical step is to seek written insurer approval and provide the referral, treatment plan, goals, cost, accident-related reasons, and any certificate of capacity material that may affect weekly payments. If funding is refused, ask whether the next step is Internal Review, SIRA assistance, or the Personal Injury Commission (PIC).
What if the insurer wants me to see a different provider?
Ask whether the insurer is arranging an assessment, requesting more information, or refusing payment for your proposed treatment. Keep the issues separate: you may still have a treating team, but payment disputes need evidence addressing causation, reasonableness, necessity, cost, and progress.
Can I change rehabilitation provider if the current plan is not helping?
A rehabilitation-provider change can be reasonable, but explain why. Useful evidence includes a GP or specialist referral, notes about lack of progress, access or language issues, a discharge or transfer summary, and a new rehabilitation plan with measurable goals.
