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).
If you were injured in a motor accident and already had a pre-existing condition, you may wonder how this affects your compensation. In New South Wales, the Compulsory Third Party (CTP) scheme covers injuries caused by motor vehicle accidents, but claims involving pre-existing injuries require careful assessment. This article explains how NSW insurers evaluate aggravation claims, what evidence is needed, and how pre-existing injuries may influence compensation outcomes.
How Do NSW CTP Insurers Assess Aggravation of Pre-existing Injuries?
Under the Motor Accident Injuries Act 2017, CTP insurers must determine whether an accident worsened a pre-existing condition. This involves assessing whether the injury is 'aggravated' by the accident. SIRA (State Insurance Regulatory Authority) guidance states that insurers must consider medical evidence showing a direct link between the accident and the worsened condition. For example, if a person with a pre-existing back injury experiences increased pain or functional loss after a crash, this could qualify as aggravation.
Insurers evaluate whether the aggravation is 'more than minimal' and whether it results in additional consequences such as prolonged recovery, increased treatment costs, or reduced quality of life. SIRA’s guidelines emphasize that claims must demonstrate a 'causal connection' between the accident and the worsened condition, not just a correlation.
What Evidence Is Needed to Prove Injury Aggravation in CTP Claims?
To support a claim for aggravated pre-existing injuries, injured people must provide:
- Medical records showing the pre-existing condition and its progression before and after the accident.
- Accident reports detailing how the collision occurred and its potential impact on the injured person.
- Witness statements or expert opinions linking the accident to the worsened condition.
- Medical opinions from treating practitioners confirming that the aggravation is significant enough to affect daily life or recovery.
SIRA advises that claims lacking clear evidence of a causal link are unlikely to succeed. For instance, if a person with a pre-existing knee condition experiences minor discomfort after an accident but no functional loss, the claim may not meet the threshold for compensation.
Can Pre-existing Injuries Affect Compensation Amounts in NSW?
Yes. Under the CTP scheme, compensation is based on the consequences of the accident, not the pre-existing condition itself. However, if the aggravation leads to additional injuries or worsened outcomes, it may qualify for extra benefits. For example:
- A person with a pre-existing back injury who develops new neurological symptoms after an accident may be eligible for additional treatment costs or income loss.
- If the aggravation results in a 'threshold injury' (as defined by SIRA), the injured person may receive weekly payments for 52 weeks.
SIRA’s guidelines clarify that pre-existing injuries are not automatically excluded from claims. However, the claimant must prove that the accident caused a 'material worsening' of the condition. This distinction is crucial, as minor aggravations may not meet the legal threshold for compensation.
Common Mistakes Injured People Make with Pre-existing Injury Claims
Injured people often make errors that weaken their claims. These include:
- Failing to document pre-existing conditions adequately before the accident. Without records, insurers may dispute the claim.
- Not seeking medical attention after the accident. Delayed treatment can make it harder to prove a causal link between the accident and the worsened condition.
- Providing inconsistent evidence. Mixed or conflicting medical opinions can undermine the claim.
- Assuming all aggravations qualify for compensation. Only injuries that meet the 'threshold injury' definition under SIRA guidelines are eligible for benefits.
To avoid these pitfalls, injured people should act quickly to gather evidence and seek professional advice. SIRA recommends consulting a medical practitioner or legal expert to assess whether the aggravation meets the legal criteria for compensation.
When Should You Seek Legal Advice?
If your claim involves a pre-existing injury, it’s essential to seek legal advice early. A solicitor can help you:
- Navigate the complex process of proving aggravation.
- Understand how SIRA’s guidelines apply to your specific case.
- Ensure you meet all evidentiary requirements.
- Explore options for disputes if your claim is rejected.
Legal professionals can also help you understand whether your claim qualifies for additional benefits such as weekly income payments or treatment costs. Remember, every claim is assessed based on its own facts, and the outcome depends on the strength of the evidence and the legal interpretation of the circumstances.
Final Steps for Injured People
If you believe your pre-existing injury has been aggravated by a motor accident, take the following steps:
- Seek immediate medical attention to document the worsened condition.
- Gather all relevant evidence, including medical records, accident reports, and witness statements.
- Consult a legal professional to assess the strength of your claim.
- Submit your claim to the relevant insurer within the required time limits.
