What is the permanent impairment threshold under NSW CTP rules?
Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).
A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).
Under the NSW Compulsory Third Party (CTP) scheme, a claimant must demonstrate a permanent impairment of at least 10% to whole person impairment (WPI) to qualify for additional compensation beyond statutory benefits. This 10% threshold is defined in the Motor Accident Injuries Act 2017 (MAIA) and is determined through a medical assessment conducted by a qualified assessor.
How do medical assessments determine permanent impairment for CTP claims?
Medical assessments are critical to establish the level of permanent impairment. A registered medical practitioner must evaluate the claimant’s injuries and provide a report detailing the WPI percentage. The assessment considers factors like:
- The nature and severity of the injury
- Long-term functional limitations
- Impact on daily activities and employment
- Medical evidence from specialist consultations
The assessor must apply the Motor Accident Guidelines, which outline clinical criteria for different impairments. For example, a spinal nerve-root injury with neurological signs may qualify as a threshold injury, while radiculopathy requires specific clinical signs.
What evidence is needed to support a permanent impairment claim?
To build a strong case, claimants should gather:
- Detailed medical records from all treating specialists
- Copies of diagnostic imaging (e.g., MRI, X-rays)
- Rehabilitation reports and treatment plans
- Evidence of ongoing symptoms and functional limitations
- Any pre-existing conditions documented by a medical professional
It is essential to ensure that the medical evidence clearly links the injury to the claimed impairment percentage. Incomplete or inconsistent records may lead to disputes over the assessment outcome.
Practical steps to prepare for a medical assessment
- Consult with a specialist to ensure your injuries are fully documented
- Prepare a list of questions for the assessor about how your injuries meet the WPI criteria
- Bring all relevant medical documents to the assessment
- Consider a second opinion if you are unsure about the assessment outcome
When to seek legal advice
If you believe your impairment assessment is inaccurate or if you face disputes over the WPI percentage, it is advisable to seek legal guidance. A solicitor can help challenge the assessment or negotiate a fair outcome based on the evidence.
Time limits and next steps
Claims must be submitted within 52 weeks of the accident for statutory benefits, but permanent impairment claims may extend beyond this period. If your claim involves long-term impairment, ensure you follow up with your insurer and keep detailed records of all communications.
