Understanding the 10% Permanent Impairment Threshold in NSW CTP Claims
In New South Wales, a person who has suffered a motor vehicle accident may be eligible for ongoing treatment and rehabilitation support if their injury results in a permanent impairment of at least 10% of their whole person. This 10% threshold is a key legal requirement under the Motor Accident Injuries Act 2017 (MAIA). It determines whether a claimant can access long-term treatment and rehabilitation benefits through the Compulsory Third Party (CTP) insurance scheme, which is administered by the State Insurance Regulatory Authority (SIRA). The threshold applies equally across Greater Sydney and the rest of NSW, and does not vary based on location, vehicle type, or whether the accident occurred on a public road, in a car park, or on private property.
How the Threshold Influences Treatment and Rehabilitation Planning
Once a claimant’s injury is assessed and confirmed to result in a permanent impairment of 10% or more, their treatment and rehabilitation planning shifts from short-term recovery to long-term management. The CTP insurer must fund treatment and rehabilitation services that are reasonable and necessary to address the ongoing impact of the injury. This includes specialist medical care, physiotherapy, psychological support, and assistive devices, as long as they are recommended by a qualified medical practitioner and approved under the Motor Accident Injuries Regulation 2017.
Rehabilitation planning must be individualised and based on a formal assessment of the claimant’s functional capacity, daily living limitations, and future needs. The plan must be developed in consultation with the claimant, their treating medical practitioner, and, where appropriate, a rehabilitation provider. The goal is to maximise recovery, maintain independence, and support return to work or education where possible. SIRA’s Motor Accident Guidelines provide detailed standards for assessing impairment and approving rehabilitation plans, ensuring consistency across Greater Sydney and the broader state.
Key Evidence and Practical Steps for Claimants
To establish eligibility for treatment and rehabilitation funding under the 10% threshold, claimants must provide clear medical evidence. This includes:
- A formal assessment of whole person impairment by a qualified medical assessor, using the criteria in the Motor Accident Injuries Regulation 2017.
- Clinical records showing the nature, duration, and impact of the injury, including diagnostic imaging, neurological assessments, and treatment progress notes.
- A detailed rehabilitation plan, prepared by a registered rehabilitation provider, outlining the type, frequency, and expected duration of services.
Claimants should notify their CTP insurer as soon as possible after receiving a permanent impairment assessment. Delaying notification may affect the timing of benefit approval. It is also important to preserve all records related to the accident, treatment, and communication with the insurer, including photographs of the scene, witness statements, and correspondence.
When the Threshold Applies and When It Does Not
The 10% threshold only applies to claims where the injury results in a permanent impairment. It does not apply to injuries that are resolved within 52 weeks, or to claims where only minor injuries (now known as threshold injuries) are present. Where a claimant’s only injuries are threshold injuries, treatment and care benefits are generally limited to 52 weeks under the MAIA, and no further rehabilitation funding is available unless a new injury arises.
If a claimant has a permanent impairment of 10% or more, they may also be eligible to claim damages for non-economic loss (such as pain and suffering) and future economic loss, provided they meet the requirements of the MAIA, including the 52-week treatment and care benefit period. However, damages are not automatically granted and depend on the nature and severity of the injury, as well as the claimant’s ability to demonstrate a significant impact on their life.
Hypothetical Example: A Claim in Greater Sydney
A 38-year-old office worker in Sydney’s inner west was involved in a rear-end collision at a traffic light in 2024. They sustained a spinal injury that, after 18 months of treatment, was assessed as resulting in a 12% whole person impairment. The medical assessor confirmed that the injury had stabilised and would not improve further. The claimant submitted the assessment to their CTP insurer, who approved a rehabilitation plan including weekly physiotherapy, a specialist pain management program, and a workplace modification to support a return to part-time duties. The plan was reviewed every six months to ensure it remained appropriate and effective.
Time Limits and Dispute Options
There are no fixed time limits for applying for treatment and rehabilitation funding after a permanent impairment is assessed, but it is advisable to act promptly. If a CTP insurer refuses to fund a treatment or rehabilitation plan, the claimant may request a review under SIRA’s dispute resolution process. If the dispute remains unresolved, the claimant may apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination. The claimant must have a formal assessment of impairment and a documented plan before initiating a dispute.
