How insurers assess liability for permanent impairment claims in NSW
Under New South Wales law, insurers assess liability for Compulsory Third Party (CTP) claims based on the 10% whole person impairment threshold. This means a claimant must demonstrate a permanent impairment of 10% or more to qualify for additional compensation beyond statutory benefits. The assessment process involves medical evidence, SIRA guidelines, and the specific circumstances of the accident.
Legal definition of the permanent impairment threshold
The threshold is defined under the Motor Accident Injuries Act 2017 as a permanent impairment that significantly affects a person’s physical or mental capacity. A whole person impairment of 10% or more is calculated using the Motor Accident Guidelines, which outline clinical criteria for assessing injuries. For example, a spinal nerve-root injury with neurological signs may meet the threshold even if radiculopathy is not present.
How insurers evaluate claims
Insurers use SIRA’s (State Insurance Regulatory Authority) guidelines to determine whether a claim meets the threshold. Key factors include:
- Medical reports from licensed practitioners detailing the nature and permanence of the injury
- Evidence of how the impairment affects daily activities or work capacity
- Alignment with SIRA’s impairment rating scales
Insurers may also consider the 52-week statutory benefit period. If a claimant’s injuries are limited to threshold injuries, weekly benefits and treatment payments generally stop after 52 weeks, unless the impairment exceeds 10%.
Practical implications for claimants in Auburn
Meeting or exceeding the 10% threshold entitles claimants to:
- Additional compensation for permanent impairment
- Access to lifetime care or income support if the impairment is severe
- Coverage of ongoing medical treatment costs
However, insurers may dispute claims by arguing the impairment is temporary, the injury does not meet SIRA criteria, or the claimant has contributed to the accident (contributory fault). Claimants should ensure medical records clearly document the impairment’s permanence and impact.
When to seek legal advice
Claimants should consult a legal professional if:
- The insurer denies the claim without a clear explanation
- Medical evidence is unclear or incomplete
- The claimant is unsure whether the impairment meets the threshold
- The accident occurred in a car park, driveway, or private property (as these locations may require individual legal assessment)
