How SIRA Assesses Permanent Impairment for CTP Claims in NSW
Under New South Wales law, a claimant must prove their injury meets the 10% whole person impairment threshold to qualify for permanent impairment compensation under the Motor Accident Injuries Act 2017. This threshold determines whether an injury is classified as permanent and eligible for specific benefits. SIRA (State Insurance Regulatory Authority) applies consistent medical and legal standards across NSW, including in Armidale, to assess whether an injury meets this threshold.
Legal Definition of Permanent Impairment
The 10% threshold is defined as a permanent loss of function that significantly impacts a person's ability to perform everyday activities. This is determined using the whole person impairment assessment outlined in the Motor Accident Guidelines. SIRA evaluates injuries based on clinical evidence, including medical reports from registered practitioners, to establish whether the impairment is both permanent and meets the 10% benchmark.
How SIRA Determines Eligibility
SIRA uses the whole person impairment framework, which considers the cumulative effect of all injuries. For example, a fractured wrist with a 5% impairment and a knee injury with a 6% impairment would total 11%, exceeding the threshold. Medical evidence must clearly show that the impairment is permanent and not likely to improve. SIRA also considers whether the injury results in long-term functional limitations, such as reduced mobility or chronic pain.
Evidence Required for Permanent Impairment Claims
To support a claim, injured persons must provide:
- Detailed medical records from a registered medical practitioner
- A completed
- Impairment Assessment Form* (SIRA Form 10)
- Evidence of ongoing treatment or rehabilitation
- Documentation of how the injury affects daily life
SIRA may request additional information, such as expert opinions or independent medical assessments, to verify the impairment rating.
Impact on Compensation Calculations
If an injury meets the 10% threshold, claimants may be eligible for:
- Permanent impairment compensation (based on the injury's severity)
- Additional benefits for long-term care or lost income
- Lifetime payments for severe impairments
However, claims for injuries below the threshold are limited to 52 weeks of weekly benefits and treatment costs, as per the Act. This distinction is critical for determining the type and duration of support available.
Practical Steps for Claimants
Injured persons should:
- Seek immediate medical attention to document the injury
- Keep all medical records and correspondence
- Complete SIRA's required forms promptly
- Avoid disclosing personal details to insurers without legal advice
If unsure whether an injury meets the threshold, claimants should consult a legal professional to review their medical evidence and assess their options.
When to Seek Legal Advice
Complex cases may involve disputes over impairment ratings, overlapping claims with workers' compensation, or challenges from insurers. Legal advice is essential when:
- The injury involves multiple body systems
- There are disputes about the permanence of the impairment
- The claimant is unsure whether they meet the threshold
SIRA provides resources to guide claimants, but legal experts can help navigate the process and ensure all requirements are met.
