Understanding pre-existing injury aggravation in NSW CTP claims
If you have a pre-existing medical condition that worsens after a motor accident in New South Wales, you may be entitled to compensation through the Compulsory Third Party (CTP) insurance scheme. This situation, where an accident aggravates a prior injury, is governed by the Motor Accident Injuries Act 2017 (MAIA), which applies to all motor accidents occurring on or after 1 December 2017. The law recognises that you can claim for the additional harm caused by the accident, even if you had a medical issue before the crash. However, the claim must demonstrate that the accident caused a measurable worsening of your condition, not just a continuation of pre-existing symptoms.
How medical assessments work for pre-existing injury claims
Medical assessments are a key part of any CTP claim involving a pre-existing injury. These assessments are conducted by independent medical practitioners approved by the State Insurance Regulatory Authority (SIRA). The purpose is to determine whether the accident caused a significant aggravation of your condition, and to assess the extent of any new or worsened impairment. The assessment will review your medical history, treatment records, and current symptoms. It is not a routine check-up but a formal evaluation to support your claim for benefits.
In Greater Sydney, assessments are typically arranged through the CTP insurer or the SIRA claims portal. You will receive a formal appointment notice, including the date, time, location, and the name of the medical assessor. It is important to attend the appointment and bring all relevant documentation. The assessor will not make a diagnosis but will form an opinion on whether the accident contributed to your current condition, and to what degree.
Practical steps to prepare for a medical assessment
To strengthen your claim and ensure the assessment is accurate and fair, you should take several practical steps before your appointment:
- Gather and bring all medical records related to your pre-existing condition, including diagnosis letters, specialist reports, imaging results (X-rays, MRIs), and treatment notes from the past 12 months.
- Keep a daily journal of your symptoms, pain levels, and functional limitations since the accident. This helps show a clear link between the crash and any worsening.
- Bring a list of all medications you are taking, including those for the pre-existing condition.
- If you have witnesses to the accident or people who can confirm changes in your abilities since the crash, provide their contact details.
- Do not alter or withhold any medical records. The insurer and SIRA will verify the information.
SIRA’s guidelines state that the medical assessor must consider all evidence, including your pre-accident health status, to determine whether the accident caused a material increase in your impairment. The burden is on you to show that the accident made your condition worse.
Time limits and dispute options
There are time limits for making a CTP claim in NSW. You must notify your insurer within 6 months of the accident, or within 6 months of becoming aware of a connection between your injury and the accident. If you are claiming for an aggravation of a pre-existing injury, this awareness date may be later than the accident date, especially if symptoms worsened gradually.
If you disagree with the medical assessment outcome, you may request a review. This can be done through the insurer or by applying to SIRA for a review of the assessment. You must submit your request within 28 days of receiving the report. Disputes are common in pre-existing injury cases, particularly when the insurer argues that the injury was not caused by the accident or that the aggravation was not significant.
When to seek independent advice
A pre-existing injury aggravation claim can be complex, especially in Greater Sydney where access to specialist medical services is high but so is the volume of claims. If you are unsure about your rights, the strength of your evidence, or how to respond to a medical assessment, it is advisable to seek independent legal advice before attending any assessment. The law does not require you to have a solicitor, but a qualified professional can help you understand your entitlements, prepare for the assessment, and ensure your rights are protected.
