What Changed in CTP Treatment Provider Disputes After the 2017 Reforms?
After the 2017 reforms to NSW’s motor accident compensation system, treatment provider disputes are governed by the Motor Accident Injuries Act 2017 (MAIA) and the Motor Accident Injuries Regulation 2017. The key change is that insurers must now provide treatment and care benefits under a structured, transparent process, with a focus on early intervention and independent review. Insurers can no longer unilaterally deny or cap treatment without a clear basis. Disputes are now resolved through formal review pathways, including internal insurer reviews and external review by the Personal Injury Commission (PIC), which replaced the former Motor Accidents Commission.
How the 2017 Reforms Changed the Dispute Process
Under the new system, if an insurer refuses or limits treatment recommended by a medical practitioner, the claimant may request an internal review within 28 days of receiving the decision. The insurer must respond within 21 days. If the claimant disagrees with the outcome, they can apply to the Personal Injury Commission for an external review. The PIC has authority to assess whether the treatment is reasonable and necessary, and to order the insurer to fund it. This process is mandatory for disputes involving treatment and care benefits, and it applies regardless of fault.
Role of the Personal Injury Commission in Dispute Resolution
The Personal Injury Commission plays a central role in resolving treatment provider disputes. It reviews decisions on treatment and care benefits, including those involving physiotherapy, psychology, medical assessments, and allied health services. The PIC considers medical evidence, treatment plans, and the Motor Accident Guidelines to determine whether a treatment is reasonable and necessary. Its decisions are binding on the insurer, and it can order funding for treatments that were previously denied or capped.
Practical Steps and Evidence That Matter
To resolve a treatment provider dispute, claimants should:
- Obtain a written treatment plan from a qualified medical practitioner, including the diagnosis, treatment goals, and expected duration.
- Keep records of all communications with the insurer, including emails, letters, and call logs.
- Submit the treatment plan and supporting medical evidence to the insurer for approval.
- If denied, request an internal review and submit all documentation.
- If the internal review is unsatisfactory, apply to the Personal Injury Commission within 60 days of the insurer’s decision.
Medical evidence that supports a treatment plan includes diagnostic imaging, clinical notes, functional assessments, and reports from treating practitioners. A claimant should not delay treatment while disputing a decision, as ongoing care may be required to prevent deterioration.
Time Limits and When to Seek Advice
Time limits apply to dispute resolution. An internal review must be requested within 28 days of receiving a denial or cap. An external review with the Personal Injury Commission must be applied for within 60 days of the insurer’s internal decision. Missing these deadlines may prevent a claimant from challenging the insurer’s decision.
A claimant should seek advice if:
- The insurer denies treatment without a clear reason.
- The insurer caps treatment below what the medical practitioner recommends.
- The insurer delays approval for more than 14 days.
- The claimant experiences worsening symptoms due to delayed treatment.
The reforms were designed to reduce delays and ensure access to necessary care. However, a challenge does not guarantee a change in decision. The PIC assesses all evidence and may uphold the insurer’s original decision if it finds the treatment was not reasonable or necessary under the Motor Accident Guidelines.
Hypothetical Example: A Claimant’s Path Through a Dispute
A 38-year-old woman was injured in a car crash in Sydney in August 2024. She was diagnosed with a whiplash injury and recommended six weeks of physiotherapy. Her insurer approved only two sessions. She requested an internal review, which was denied. She then applied to the Personal Injury Commission with a treatment plan from her physiotherapist, MRI results showing cervical disc degeneration, and a letter from her GP confirming functional impairment. The PIC reviewed the evidence and ordered the insurer to fund the full course of treatment. The insurer complied within 14 days.
