Permanent Impairment Threshold and Documentation Checklist for NSW CTP Claims
In New South Wales, a claimant must prove a permanent impairment of at least 10% whole person impairment (WPI) to qualify for certain benefits under the Compulsory Third Party (CTP) scheme. This threshold determines whether a claimant is eligible for ongoing payments, treatment benefits, or compensation for loss of income. Understanding what evidence is required to meet this threshold is critical for injured road users seeking compensation.
Legal Framework Behind the 10% Threshold
The Motor Accident Injuries Act 2017 governs CTP claims in NSW. Under this legislation, a permanent impairment of 10% WPI or more qualifies a claimant for benefits such as weekly income payments and treatment and care benefits. The threshold is defined by the Motor Accident Guidelines, which outline how medical professionals assess impairment. For example, a spinal nerve-root injury with neurological signs may still meet the threshold even if it does not produce radiculopathy, as specified in the guidelines.
What Medical Evidence is Required?
To prove permanent impairment, claimants must provide:
- A detailed medical report from an accredited assessor
- Evidence of ongoing impairment, such as MRI scans or clinical notes
- A whole person impairment assessment confirming 10% or more
- Documentation of how the injury affects daily activities or work capacity
SIRA (State Insurance Regulatory Authority) evaluates claims based on these records. For example, a claimant with a 12% impairment from a whiplash injury would need to provide evidence that their condition has stabilized and meets the 10% threshold.
Common Pitfalls in Documentation
Claimants often fail to:
- Obtain an impairment assessment from an accredited medical professional
- Document how the injury impacts their ability to work
- Preserve records of pre-accident income for loss of earnings claims
- Submit evidence within the 52-week statutory benefit period
For instance, a cyclist with a 10% impairment who does not provide evidence of ongoing treatment after 52 weeks may lose access to weekly benefits, even if their impairment persists.
When to Seek Legal Advice
Disputes over impairment assessments or benefit eligibility often require legal intervention. Claimants should consult a solicitor if:
- The insurer disputes the 10% threshold
- The claimant’s condition worsens after the 52-week period
- There are questions about the accuracy of medical records
- The claimant needs to dispute a decision to terminate benefits
Final Steps for Claimants
To maximise compensation, injured claimants should:
- Obtain a whole person impairment assessment from an accredited assessor
- Keep detailed records of all medical treatments and expenses
- Submit evidence within the 52-week statutory period
- Seek legal advice if the insurer disputes the claim

How to Prepare Your Documentation
Claimants should:
- Gather all medical records, including GP notes and specialist reports
- Obtain a copy of the impairment assessment report
- Document how the injury affects daily life, such as difficulty with mobility or work
- Preserve evidence of pre-accident income for loss of earnings claims
Example: A Claimant with a 10% Impairment
Consider a motorcyclist who sustained a 10% WPI injury from a collision. They must provide:
- A medical report confirming the 10% impairment
- Evidence of ongoing treatment, such as physiotherapy records
- Proof of income loss, such as payslips or employer statements
This example illustrates how claimants must meet both the legal threshold and provide sufficient evidence to support their claim.
Final Advice
CTP claims depend on the date of the accident, the nature of the injury, and the evidence provided. Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
