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 you've suffered a motor accident that worsened a pre-existing injury, you may be eligible for compensation under NSW's Compulsory Third Party (CTP) scheme. Rural and remote residents face unique challenges in accessing medical assessments, but understanding the legal process and preparing evidence can improve your claim. This article explains how NSW CTP insurers evaluate pre-existing injury aggravation claims, what medical evidence matters, and practical steps to prepare for assessments in rural areas.

How NSW CTP Insurers Assess Pre-existing Injury Aggravation Claims

Under the Motor Accident Injuries Act 2017, CTP insurers must assess whether a crash has aggravated a pre-existing condition. This requires medical evidence showing:

  • A pre-existing injury documented in medical records
  • A causal link between the accident and worsening symptoms
  • That the aggravation caused additional disability or treatment needs

SIRA (State Insurance Regulatory Authority) guidelines state that insurers must consider the full medical history. For example, if a person with a pre-existing knee injury experiences increased pain and reduced mobility after a crash, this could qualify as an aggravation. However, insurers may dispute claims if the pre-existing condition was not properly documented or if the aggravation is deemed minimal.

Medical Evidence Required for Rural NSW CTP Claims

Rural residents may struggle to access specialists or specialist clinics, but SIRA requires evidence to support a claim. Key documents include:

  • Pre-existing injury medical records (e.g., MRI scans, surgery notes)
  • Post-crash medical reports from general practitioners or specialists
  • Evidence of worsened symptoms (e.g., increased pain, mobility issues)
  • Specialist opinions confirming the aggravation

In rural areas, securing a specialist opinion may require telehealth consultations or referrals to regional medical centers. SIRA advises claimants to request a second medical opinion if they believe their condition has worsened.

Preparing for Medical Assessments in Remote Areas

To prepare for assessments, rural residents should:

  1. Gather all pre-existing injury records, including dates of diagnosis and treatment
  2. Document post-crash symptoms with a GP or physiotherapist
  3. Request a specialist referral through local health services
  4. Use telehealth services to consult with specialists if in-person visits are difficult
  5. Keep a journal of symptoms, medication use, and daily limitations

SIRA guidelines emphasize that claimants must provide evidence of a 'threshold injury' under the Motor Accident Guidelines. This means the aggravation must meet the clinical criteria for a soft tissue injury or spinal nerve-root injury, as defined in the guidelines.

Time Limits and Dispute Resolution

CTP claims must be submitted within 52 weeks of the accident for benefits related to threshold injuries. If your claim involves a pre-existing injury aggravation, you may have longer time limits, but this depends on the specific circumstances. Disputes may arise if insurers challenge the link between the accident and the aggravation, especially in rural areas where specialist access is limited. In such cases, seeking independent medical opinions or legal advice can help resolve disputes.

Example Scenario

Consider a rural resident with a pre-existing lumbar strain who experiences increased pain and nerve symptoms after a car crash. A GP documents worsened symptoms, and a telehealth physiotherapist confirms the aggravation meets the threshold injury criteria. This evidence supports a CTP claim for additional treatment and income loss.

When to Seek Legal Advice

If you're unsure whether your claim meets CTP criteria, or if your insurer disputes the aggravation, legal advice may be necessary. A solicitor can help you:

  • Navigate SIRA's claim process
  • Challenge disputed medical opinions
  • Ensure you meet all evidentiary requirements

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
