How NSW CTP Insurers Assess Liability for Pre-existing Injury Aggravation
Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).
If a road accident worsens a pre-existing injury, NSW CTP insurers must determine whether the accident caused the aggravation. This process involves assessing medical evidence, the nature of the injury, and the accident’s role in worsening the condition. Understanding how insurers evaluate these claims is critical for claimants seeking compensation.
Key Factors Insurers Consider
NSW CTP insurers evaluate claims by examining:
- Medical evidence showing the pre-existing injury and its connection to the accident
- Clinical records documenting the injury’s progression before and after the accident
- Accident details such as speed, impact, and how the collision affected the injured person
- Expert opinions from medical practitioners to determine if the aggravation was caused by the accident
The Motor Accident Injuries Act 2017 (MAIA) and SIRA guidelines state that insurers must consider whether the accident contributed to the injury’s worsening. If the pre-existing condition was stable before the accident, insurers must prove the aggravation was unrelated to the collision.
Proving Aggravation: What Evidence Matters
Claimants should gather:
- Medical records showing the pre-existing injury’s history and how the accident worsened it
- Accident reports from police or witnesses detailing the incident
- Statements from medical practitioners confirming the aggravation
- Evidence of the accident’s impact such as photographs, vehicle damage, or medical imaging
For example, if a person had a pre-existing back injury and a car accident caused additional spinal damage, medical evidence must show the accident exacerbated the condition. Insurers may challenge claims where the aggravation is not clearly linked to the accident.
Time Limits and Dispute Options
Claims must be made within 52 weeks of the accident if only threshold injuries (minor soft tissue injuries) are involved. However, if the aggravation results in a more severe injury, the 52-week limit does not apply. Claimants should notify their insurer promptly and request a review if the assessment is disputed.
If an insurer denies a claim, claimants can:
- Request a review by the insurer’s internal team
- Seek mediation through SIRA
- Lodge a complaint with the NSW Civil and Administrative Tribunal (NCAT)
When to Seek Legal Advice
Insurers may undervalue claims where the aggravation is complex or the pre-existing injury is not well-documented. Claimants should consult a legal professional if:
- The insurer disputes the link between the accident and the aggravation
- The claimant’s medical records are incomplete or unclear
- The injury results in long-term disability or chronic pain
Legal experts can help challenge an insurer’s assessment and ensure claimants receive fair compensation for their injuries.
