How Treatment Costs Are Funded in NSW Multi-Vehicle Pile-Up CTP Claims

In a multi-vehicle pile-up in Western Sydney, treatment costs are generally funded under the NSW Compulsory Third Party (CTP) insurance scheme administered by the State Insurance Regulatory Authority (SIRA). If you were injured in such an incident, you may be entitled to funding for medical treatment, rehabilitation, and allied health services through your CTP claim. This funding is available regardless of who caused the accident, as long as you were a driver, passenger, pedestrian, cyclist, or motorcyclist involved in a motor vehicle accident that occurred in NSW. The CTP insurer responsible for the vehicle that caused the injury (or the nominal defendant insurer if fault is disputed) must cover reasonable and necessary treatment costs incurred as a result of the accident.

What Treatment Costs Are Covered Under SIRA

SIRA’s guidelines define treatment and care benefits as covering medical treatment, allied health services, and rehabilitation that are reasonable and necessary for the recovery from injuries sustained in a motor accident. This includes physiotherapy, chiropractic care, psychological counselling, occupational therapy, and medical assessments. For injuries resulting from a multi-vehicle pile-up, the insurer must fund treatment that is directly linked to the accident, as confirmed by a medical practitioner. Treatment must be provided by a registered health professional and must be clinically justified. The insurer may request medical records, treatment plans, and progress reports to verify the necessity and reasonableness of the care.

Evidence Required to Claim Treatment Costs

To secure funding for treatment costs, you must provide evidence that supports your claim. This includes:

  • A detailed medical report from your treating practitioner confirming the nature and cause of your injuries.
  • A treatment plan outlining the type, frequency, and duration of therapy.
  • Itemised invoices or receipts for all treatment services received.
  • A record of any communication with the insurer, including written correspondence and call logs.
  • Photographs of the accident scene, vehicle damage, or injury symptoms, if available.
  • Witness statements, if applicable, describing how the accident occurred and the immediate impact on your health.

In a multi-vehicle pile-up, where liability is disputed or unclear, the insurer may request a formal accident report from the police or a detailed statement from you about the sequence of events. It is essential to preserve all documentation and avoid delays in reporting treatment, as failure to notify the insurer within a reasonable time may affect the approval of claims.

How SIRA Determines Eligibility for Treatment Funding

SIRA determines eligibility for treatment funding based on the Motor Accident Injuries Act 2017 and the Motor Accident Injuries Regulation 2017. The key criteria are that the injury must have arisen from a motor vehicle accident in NSW, and the treatment must be reasonable and necessary for recovery. In multi-vehicle incidents, the insurer may assess whether the injury was caused by impact, whiplash, or secondary trauma from being thrown or struck during the crash. The insurer may also consider whether the injury was pre-existing or unrelated to the accident.

If the injury is classified as a threshold injury (such as a soft tissue injury), the insurer must still fund treatment and care benefits, but damages for non-economic loss are not available unless the injury meets the threshold for a permanent impairment. However, treatment and care benefits are not limited to a fixed duration in such cases, provided they remain reasonable and necessary. For non-threshold injuries, treatment funding continues until recovery or a medical assessment determines that further treatment is not warranted.

Practical Steps to Secure Treatment Funding

  1. Seek medical attention immediately after the accident, even if symptoms are delayed.
  2. Notify your CTP insurer as soon as possible, ideally within 28 days of the accident.
  3. Request a claim form from the insurer and complete it with full details of the accident and injuries.
  4. Provide all supporting evidence, including medical reports and invoices.
  5. Keep a copy of all correspondence and documents.
  6. If your claim is denied or delayed, you may request a review from the insurer or seek assistance from SIRA’s claims support team.

A hypothetical example: A pedestrian in Western Sydney was struck by a vehicle during a multi-vehicle pile-up on the M4 motorway in August 2024. The individual sustained a neck injury and required six months of physiotherapy. The CTP insurer approved funding for all treatment after reviewing medical reports and a police accident report. The treatment was funded under the statutory treatment and care benefits, as the injury was not classified as a threshold injury.

Time Limits and Dispute Options

There is no fixed deadline for notifying an insurer about treatment costs, but delays may affect the approval process. It is advisable to report treatment within a reasonable timeframe. If an insurer refuses to fund treatment, you may request a review under the insurer’s internal dispute resolution process. If unresolved, you can apply to SIRA for a determination. SIRA may also assist in mediating disputes between claimants and insurers.
