Understanding the Role of Medical Assessments in NSW CTP Claims
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).
Medical assessments are a key part of the claims process under the Motor Accident Injuries Act 2017 (MAIA). These assessments are conducted by independent medical practitioners to determine the nature, severity and impact of injuries sustained in a motor accident. The outcome of these assessments influences whether a claimant qualifies for treatment and care benefits, weekly income payments, or damages. In Greater Sydney, as across NSW, these assessments are governed by the Motor Accident Injuries Regulation 2017 and the Motor Accident Guidelines issued by the State Insurance Regulatory Authority (SIRA).
How SIRA Guides the Claims Assessment Process
SIRA provides the framework for assessing motor accident claims, including medical evaluations. The Motor Accident Guidelines set out the criteria for determining whether an injury is a threshold injury, which affects eligibility for damages. These guidelines define specific clinical signs for conditions such as radiculopathy, and clarify that a spinal nerve-root injury may still qualify as a soft-tissue injury if it produces neurological signs other than radiculopathy. This distinction is critical for claimants in Greater Sydney, as it determines whether a claim may proceed to damages.
SIRA also oversees the assessment of whole person impairment (WPI), which is used to calculate compensation for permanent impairment. The assessment must be conducted by a qualified medical practitioner using the Australian Medical Association’s impairment rating guidelines. The claimant’s WPI score, combined with the degree of permanent loss of function, determines the value of any damages claim.
Practical Steps to Prepare for a Medical Assessment
To ensure a medical assessment is fair and accurate, claimants should take several practical steps before attending. First, obtain a full copy of your medical records from your treating practitioner, including diagnostic reports, imaging results, and notes on treatment progress. These documents help the assessor understand the full context of your injuries and recovery.
Second, keep a daily journal of symptoms, pain levels, and functional limitations for at least four weeks before the assessment. This record provides objective evidence of ongoing impact and supports claims for treatment and care benefits or damages.
Third, bring any relevant correspondence with your insurer, including letters, emails, and claim forms. This ensures the assessor has a complete picture of your claim history and any prior communications about your injuries.
Fourth, attend the assessment on time, dressed appropriately for any physical tests, and bring any assistive devices you use daily, such as a walking aid or brace. Be honest and clear in your responses, and do not exaggerate symptoms.
What to Expect During the Assessment
The medical assessor will review your records, conduct a physical examination, and ask questions about your injury, treatment, and daily functioning. They may request additional tests, such as a repeat MRI or nerve conduction study, if they believe more evidence is needed. You have the right to have a support person present, and you may request a copy of the assessment report after it is issued.
If you disagree with the assessment, you may request a review by a different medical practitioner. This process is governed by SIRA’s dispute resolution procedures and must be initiated within 28 days of receiving the report.
Time Limits and Dispute Options
There are time limits for making claims and challenging assessments. Under the MAIA, a claim must be made within three years of the accident. If you are seeking damages, you must have a medical assessment that confirms a threshold injury or a permanent impairment of at least 10%. Failure to meet these requirements may prevent you from claiming damages.
If you believe the assessment was inaccurate or unfair, you may apply to SIRA for a review. You must provide evidence that supports your claim, such as updated medical reports, a second opinion from a treating practitioner, or a record of ongoing functional limitations.
When to Seek Independent Legal Advice
Medical assessments can significantly affect the outcome of a CTP claim. While SIRA provides guidance, the interpretation of medical evidence and legal thresholds can be complex. If you have a serious or ongoing injury, or if your claim is disputed, it is advisable to seek independent legal advice before attending an assessment.
A solicitor can help you understand your rights, prepare your medical evidence, and represent you in any dispute. They can also assist in ensuring that your claim is not limited by the 52-week rule, which applies only to claims where the only injuries are threshold injuries and weekly benefits are capped after 52 weeks.
Hypothetical Example: A Claimant in Sydney
A 38-year-old cyclist in Sydney was involved in a motor vehicle accident in June 2025. They sustained a whiplash injury and were diagnosed with a cervical spine nerve-root injury. The injury caused ongoing neck pain, reduced mobility, and difficulty concentrating at work. After 18 months of treatment, they underwent a medical assessment under SIRA’s guidelines. The assessor found evidence of neurological signs but not radiculopathy, which qualified the injury as a soft-tissue injury under the Motor Accident Guidelines. The claimant was able to proceed with a damages claim because the injury met the threshold criteria. Their legal representative helped them submit updated MRI reports and a daily symptom log, which strengthened their case.
