How CTP Insurers Assess Claims in NSW

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).

Under the Motor Accident Injuries Act 2017, insurers in New South Wales must determine whether a claimant qualifies for statutory benefits. This process involves assessing the nature of injuries, medical evidence, and the circumstances of the accident. In Auburn, claimants often seek clarity on how insurers interpret the law, particularly regarding threshold injuries and long-term benefits.

Key Factors in Insurer Assessments

CTP insurers evaluate claims based on the following criteria:

  • Injury type: The injury must meet the definition of a 'threshold injury' under the Motor Accident Guidelines. For soft tissue injuries, the insurer must confirm a spinal nerve-root injury with neurological signs, excluding radiculopathy unless specific clinical signs are present.
  • Medical evidence: Doctors must document injuries using the guidelines. For example, a soft tissue injury requiring treatment must show a 'significant and persistent' impact on daily activities.
  • Claimant's circumstances: Insurers consider the claimant's pre-accident health, occupation, and lifestyle. A full-time worker with a minor injury may receive different benefits than a retired person.
  • Time limits: Statutory benefits for threshold injuries typically last 52 weeks. After this period, insurers may stop payments unless the injury meets the 'whole person impairment' threshold under s 3.28 of the Act.

Challenging an Insurer's Decision

If an insurer denies or reduces benefits, claimants can:

  1. Request a review: Under s 4.4 of the Motor Accident Injuries Act 2017, claimants can ask the insurer to reconsider their decision within 28 days of receiving the notice.
  2. Submit new evidence: If medical records or accident reports were incomplete, provide updated documentation to support the claim.
  3. Seek independent assessment: SIRA (State Insurance Regulatory Authority) may require a second opinion from a registered medical practitioner.
  4. Consult a legal professional: If the insurer refuses to review or disputes the claim, a solicitor can help challenge the decision through the NSW Civil and Administrative Tribunal (NCAT).

Role of SIRA Guidelines

SIRA's Motor Accident Guidelines provide the framework for insurers to assess injuries. For example, a claimant with a soft tissue injury must demonstrate:

  • A spinal nerve-root injury with neurological signs (e.g., numbness, weakness)
  • Clinical evidence of pain or restricted movement
  • A significant impact on daily activities

Insurers must apply these guidelines consistently. If a claimant believes the insurer misinterpreted the guidelines, they can request a written explanation of the decision.

Example: Soft Tissue Injury in Auburn

Consider a claimant who suffered a soft tissue injury in a car accident in Auburn. The insurer may deny benefits if:

  • The injury does not meet the spinal nerve-root criteria
  • Medical records lack evidence of neurological signs
  • The claimant's pre-accident activity level is not documented

In such cases, the claimant should seek a second medical opinion and review the insurer's application of the Motor Accident Guidelines.

When to Seek Legal Advice

Claimants should consult a solicitor if:

  • The insurer refuses to review a claim
  • Benefits are reduced without a clear explanation
  • The claimant is unsure how to challenge a decision

A lawyer can help navigate the process, ensure all evidence is submitted correctly, and represent the claimant at NCAT if needed.
