How NSW Insurers Assess Pre-existing Injury Aggravation

In New South Wales, insurers evaluate claims where a motor accident worsens a pre-existing injury by assessing whether the accident caused a 'material worsening' of the condition. Under the Motor Accident Injuries Act 2017, the key question is whether the accident significantly increased the severity of the injury, leading to additional pain, disability, or medical costs. SIRA (State Insurance Regulatory Authority) provides guidelines for this, emphasizing that insurers must consider medical evidence, including pre-accident records and post-accident assessments.

Practical Steps for Rural and Remote Claimants

Claimants in rural or remote areas face unique challenges, such as limited access to specialists or delayed medical assessments. To support a claim, gather:

  • Detailed medical records showing the pre-existing injury and its progression
  • Evidence of the accident (e.g., police reports, witness statements)
  • Post-accident medical reports linking the aggravation to the incident
  • Income records if claiming lost wages

Insurers may request independent medical opinions, which can be harder to access in remote areas. Claimants should seek local medical professionals who can document the worsening condition.

Time Limits and Dispute Options

CTP claims must be submitted within 52 weeks of the accident if seeking weekly benefits for threshold injuries. However, claims for non-threshold injuries (e.g., severe nerve damage) are not subject to this limit. If an insurer denies a claim, claimants can:

  • Request a review of the decision
  • Submit additional evidence
  • Seek mediation through SIRA

In rural areas, delays in processing claims are common. Claimants should act quickly to avoid missing deadlines and consider seeking legal advice if disputes arise.

Example: Aggravation of a Pre-existing Back Injury

A claimant with a pre-existing herniated disc may experience increased pain and nerve damage after a car accident. Medical evidence showing worsened symptoms and a direct link to the accident would support a claim. Insurers may dispute this if they claim the worsening was due to natural progression, requiring expert testimony to counter.

When to Seek Legal Advice

Insurers often deny claims based on technicalities, such as incomplete medical records or failure to prove aggravation. In rural areas, claimants may need assistance navigating complex SIRA guidelines or securing independent medical assessments. Legal advice can help challenge unfair decisions and ensure all evidence is properly submitted.
