Vehicle Modifications and Medical Assessments for CTP Claims in NSW

This article explains how vehicle modifications for injury recovery are assessed in NSW CTP claims, the evidence required to support such claims, and how to prepare for medical assessments. It clarifies that modifications are not automatic entitlements but are evaluated based on medical necessity and functional impact.

Understanding Vehicle Modifications in CTP Claims

If you have been injured in a motor accident in New South Wales and now require vehicle modifications such as hand controls, steering aids or adapted seating, your claim for Compulsory Third Party (CTP) compensation may involve a medical assessment to determine the nature and impact of your injury. These modifications are not automatic entitlements but are assessed as part of your claim for treatment and care benefits, or as part of a damages claim if you meet the threshold for serious injury.

The Motor Accident Injuries Act 2017 (MAIA) and the Motor Accident Injuries Regulation 2017 set out the framework for CTP claims in NSW. Under this scheme, medical assessments are conducted to determine the extent of your injury, your capacity for recovery, and whether you are eligible for ongoing treatment and care benefits or damages. Vehicle modifications may be considered as part of your treatment plan, but they are not a standalone basis for compensation.

How Vehicle Modifications Affect Medical Assessments

Vehicle modifications are assessed as part of your overall functional capacity and injury profile. The medical assessor will review whether the modification is medically necessary, whether it is appropriate to your injury, and whether it is expected to improve your ability to drive or perform daily activities. The assessment will consider whether the modification is a permanent or temporary measure, and whether it is required due to a permanent impairment.

SIRA (the State Insurance Regulatory Authority) does not approve modifications directly. Instead, the medical assessor will determine whether the modification is reasonable and necessary in the context of your injury and recovery. For example, if you have a spinal cord injury resulting in loss of function in your lower limbs, hand controls may be deemed necessary to maintain mobility and independence. The assessor will also consider whether the modification is consistent with your treatment plan and whether it is likely to be effective.

Preparing for Your Medical Assessment

To prepare for a medical assessment involving vehicle modifications, you should:

  • Obtain a detailed medical report from your treating medical practitioner that outlines your injury, functional limitations, and the medical rationale for the modification.
  • Provide a copy of any recommendation or prescription for the modification from your medical practitioner or rehabilitation specialist.
  • Gather evidence of the modification’s use, including photographs, installation records, and correspondence with the provider.
  • Keep a record of how the modification has affected your daily life, including any improvements in mobility, independence, or safety.
  • Be ready to explain how the modification supports your rehabilitation and whether it has reduced your reliance on others.

SIRA’s guidance states that medical assessments are designed to assess your current and future needs, including assistive technology. You should not expect to receive a modification simply because you have been injured. The assessment will focus on whether the modification is medically necessary and whether it is likely to improve your functional capacity.

Evidence That Matters

The following types of evidence are commonly relied upon in assessments involving vehicle modifications:

  • A report from a specialist in rehabilitation medicine or a physical medicine and rehabilitation (PM&R) physician.
  • Documentation from a vehicle modification provider, including a description of the equipment, how it was fitted, and its purpose.
  • Evidence of your driving history and ability prior to the accident, including any licence or driving assessment records.
  • A functional capacity assessment that demonstrates how the modification impacts your ability to perform daily tasks or return to driving.

If you have a pre-existing condition that affects your mobility, the assessor will consider whether the modification is addressing a new or aggravated impairment due to the accident. The assessment will not be based solely on the presence of a modification but on the medical need for it.

Time Limits and Procedural Requirements

Under the Motor Accident Injuries Act 2017, you must notify your insurer of your claim within a reasonable time after the accident. While there is no fixed deadline for notifying a claim, delays may affect the insurer’s ability to investigate and assess your entitlements.

If you are seeking a vehicle modification as part of your treatment and care benefits, you must apply for approval through your insurer. The insurer may require a medical report or assessment before approving the modification. If the insurer refuses approval, you may request a review or apply to SIRA for a determination.

For claims involving damages, the 52-week rule applies where your only injuries are threshold injuries. In such cases, treatment and care benefits are generally limited after 52 weeks. However, if a vehicle modification is considered a necessary part of your long-term recovery and is supported by medical evidence, it may be approved beyond that period.

When to Seek Advice

Preparing for a medical assessment involving vehicle modifications can be complex. The outcome depends on the nature of your injury, the medical evidence, and how the modification supports your recovery. You may benefit from independent legal or medical advice to ensure your evidence is complete and your position is clearly presented.

A hypothetical example: A 42-year-old driver sustained a spinal injury in a motor accident in Sydney. Following surgery and rehabilitation, a specialist recommended hand controls to allow him to drive again. The medical assessor reviewed his functional capacity, confirmed the need for the modification, and approved it as part of his treatment and care plan. The approval was supported by a report from a rehabilitation physician and a detailed assessment of his driving ability.
