Pre-existing Injury Aggravation, What the PIC Expects in Disputes (Bega)
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 a motor accident worsens a pre-existing medical condition, claimants in Bega must prove the aggravation to access compensation. The Personal Injury Commission (PIC) evaluates such claims based on medical evidence, the nature of the aggravation, and whether the accident caused a new or worsened injury. This article explains how to challenge PIC decisions and what evidence matters.
Key Factors the PIC Considers
The PIC assesses pre-existing injury aggravation claims by examining:
- Medical records showing the pre-accident condition and its progression
- Evidence of aggravation from doctors, such as worsened pain, mobility issues, or new symptoms
- Timing of the aggravation, whether the accident directly caused the worsening
- Pre-existing injury documentation to establish the baseline condition
For example, if a claimant had a pre-existing knee injury and the accident caused a meniscus tear, the PIC would require medical evidence linking the tear to the crash, not pre-existing wear and tear.
Proving Injury Aggravation in CTP Disputes
To challenge a PIC decision, claimants must:
- Provide updated medical reports from specialists confirming the aggravation
- Submit expert opinions explaining how the accident worsened the condition
- Highlight new symptoms or complications that did not exist before the accident
- Demonstrate a direct causal link between the accident and the aggravation
The PIC may request additional evidence, such as imaging or specialist reports, to verify the claim.
Time Limits and Dispute Options
Claimants must notify the PIC of disputes within 28 days of receiving a decision. If the PIC denies the claim, they can:
- Request an internal review within 28 days
- Seek a medical dispute resolution through the PIC's process
- Appeal to the NSW Civil and Administrative Tribunal (NCAT)
The 52-week statutory benefit rules apply if the aggravation is a threshold injury (under the Motor Accident Injuries Act 2017 s 4.4). After 52 weeks, weekly benefits may stop unless the injury meets higher impairment thresholds.
Practical Steps for Claimants
- Keep detailed medical records showing the pre-accident condition and post-accident changes
- Document all communication with the PIC, including dates and responses
- Consult a medical expert to explain how the accident worsened the injury
- Submit evidence promptly to avoid missing time limits
If the PIC denies the claim, claimants should seek legal advice to explore dispute options. The PIC's decision is not final and can be challenged through formal processes.
When to Seek Legal Advice
Claimants should consult a solicitor if:
- The PIC denies the claim despite medical evidence
- The aggravation is unclear or disputed
- The claimant needs help navigating the internal review or appeal process
Legal professionals can help challenge PIC decisions and ensure claimants receive fair compensation for aggravated pre-existing injuries.
