How NSW CTP Insurers Assess Liability for Pre-Existing Injuries Aggravated in Western Sydney

If you've been in a motor accident in Western Sydney and your existing injury has worsened, you may be wondering how your claim will be assessed. NSW CTP insurers evaluate claims involving pre-existing injuries by considering whether the accident aggravated the injury and if the claimant is eligible for compensation. This process is governed by the Motor Accident Injuries Act 2017 and the Motor Accident Guidelines.

What Insurers Look For in Claims Involving Pre-Existing Injuries

When assessing a claim where a pre-existing injury has been aggravated, insurers will typically look for:

  • Evidence that the injury existed before the accident
  • Medical records showing the injury worsened after the accident
  • A link between the accident and the aggravation of the injury
  • Proof that the injury is not a result of other factors

Insurers may also consider the type of injury, the severity of the aggravation, and whether the injury meets the threshold for compensation under the scheme.

What You Can Claim for an Aggravated Pre-Existing Injury

If your claim is accepted, you may be eligible for:

  • Treatment and care benefits
  • Weekly income payments
  • Compensation for pain, suffering and loss of enjoyment of life

These benefits are available under the CTP scheme, but eligibility depends on the injury being aggravated by the accident and not being a result of other factors.

Dispute Options if the Insurer Refuses Liability

If your insurer refuses to accept liability for an aggravated pre-existing injury, you have options to dispute their decision. You can:

  • Request a review of the decision by the insurer
  • Submit additional evidence to support your claim
  • Seek a medical assessment to demonstrate the aggravation of the injury
  • Lodge a complaint with the Personal Injury Commission

It's important to note that a challenge does not guarantee a changed decision. The insurer will still need to be convinced that the claim is valid based on the evidence provided.

Practical Steps to Take When Disputing a Refusal of Liability

To effectively dispute a refusal of liability, you should:

  • Gather all relevant medical records and evidence
  • Submit a written request for a review of the decision
  • Consider seeking independent medical opinions if needed
  • Keep a record of all correspondence with the insurer

These steps can help you build a stronger case and demonstrate the validity of your claim.

When to Seek Independent Advice

If you're unsure about your options or need help navigating the dispute process, it may be beneficial to seek advice from a legal professional. An experienced solicitor can help you understand your rights and guide you through the process of disputing a refusal of liability.
