How Insurers Evaluate Liability in CTP Treatment Disputes

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).

When a treatment provider disputes liability in a Compulsory Third Party (CTP) claim, insurers assess the situation based on the Motor Accident Injuries Act 2017 and SIRA guidelines. This process determines whether treatment is approved, capped, or denied. Understanding the factors insurers consider is critical for claimants and providers in Ballina.

Key Factors in Liability Assessments

Insurers evaluate liability by examining:

  • Medical necessity - whether treatment aligns with the injury’s severity and clinical guidelines.
  • Documentation - records like medical reports, treatment plans, and correspondence with the insurer.
  • SIRA’s Motor Accident Guidelines - which outline acceptable treatment for threshold injuries (e.g., soft tissue injuries). For example, a spinal nerve-root injury with neurological signs may qualify as a threshold injury under the guidelines.
  • Insurer’s internal protocols - including whether the treatment meets the insurer’s defined ‘approved’ criteria.

If an insurer denies or limits treatment, they must provide written reasons. Claimants should request this documentation to understand the basis of the decision.

Practical Steps for Claimants and Providers

To resolve disputes, claimants and providers should:

  • Request a detailed explanation of the insurer’s decision, including references to specific sections of the Motor Accident Injuries Act 2017 or SIRA guidelines.
  • Submit additional evidence such as updated medical reports, specialist opinions, or evidence of treatment necessity.
  • Engage a medical expert to clarify whether the treatment meets the threshold injury criteria.
  • Review the 52-week benefit limit - if the injury is a threshold injury, weekly benefits and treatment payments may be capped after 52 weeks under s 4.4 of the Motor Accident Injuries Act 2017.

Time Limits and Dispute Resolution

CTP claims must be submitted within 52 weeks of the accident (s 3.28). If a dispute arises after this period, the insurer may refuse to cover treatment. For disputes within the time limit, claimants can:

  • Appeal the insurer’s decision through the Personal Injury Commission (PIC) medical dispute pathway.
  • Request an internal review by the insurer, which may involve a medical expert assessing the treatment’s necessity.

It’s important to note that a dispute does not guarantee a changed decision. The PIC’s role is to review the evidence, not to overturn the insurer’s initial assessment.

Example Scenario

Consider a claimant in Ballina who sustained a soft tissue injury and sought physiotherapy. The insurer denied the treatment, citing a lack of ‘clinical necessity’ under the Motor Accident Guidelines. The claimant could dispute this by:

  1. Submitting a medical report confirming the injury’s severity.
  2. Demonstrating that the treatment aligns with SIRA’s guidelines.
  3. Requesting an internal review with the insurer.

When to Seek Legal Advice

If the insurer’s decision is unclear, or if the claimant believes the treatment is necessary but denied, legal advice is advisable. A solicitor can help challenge the insurer’s interpretation of the guidelines or dispute the 52-week benefit cap.
