A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).
When treatment providers dispute CTP insurer decisions in Western Sydney, the key question is: what factors do insurers use to assess liability? Under NSW law, insurers must evaluate claims based on medical evidence, treatment necessity, and SIRA guidelines. This article explains the legal framework, practical steps, and dispute resolution options for treatment providers and claimants.
Legal Framework for CTP Liability Assessments
NSW CTP insurers assess liability by applying the Motor Accident Injuries Act 2017 and SIRA guidelines. Insurers must consider whether treatment is 'reasonably necessary' and aligns with the injury's severity. For example, if a claimant requires physiotherapy for a soft-tissue injury, the insurer must verify that the treatment meets the 'threshold injury' criteria under the Motor Accident Guidelines.
Insurers also evaluate whether the treatment provider's recommendations are supported by medical evidence. SIRA's 'What you can claim' page outlines that weekly income payments and treatment benefits depend on the injury's impact on the claimant's ability to work. If a dispute arises over the necessity of a treatment, insurers may request additional medical documentation to assess alignment with these criteria.
Practical Steps for Treatment Providers
Treatment providers should ensure all claims include:
- Detailed medical records showing the injury's progression
- Treatment plans that explicitly link to the injury's severity
- Evidence of the claimant's functional limitations
In Western Sydney, insurers often request a 'treatment necessity assessment' form from the provider. This form must confirm that the treatment is 'reasonably necessary' and not excessive. Providers should also retain copies of all correspondence with insurers, as these records may be critical if a dispute escalates.
Time Limits and Dispute Resolution
CTP insurers must respond to treatment disputes within 28 days of receiving new evidence, per SIRA guidelines. If an insurer declines a claim, the claimant has 28 days to request a review. For unresolved disputes, the Personal Injury Commission (PIC) offers a medical dispute pathway. This process allows independent medical experts to assess whether the treatment aligns with the injury's severity.
It's important to note that a challenge to an insurer's decision does not guarantee a changed outcome. The PIC's role is to determine whether the insurer's assessment was 'reasonable, ' not to overturn decisions outright. Claimants should seek legal advice if an insurer's refusal appears to contradict SIRA guidelines.
Hypothetical Example: Soft-Tissue Injury Dispute
Consider a claimant who sustained a soft-tissue injury (e.g., a whiplash-related strain) after a car accident. The insurer approves treatment for 52 weeks but later disputes the need for continued therapy. Under the Motor Accident Injuries Act 2017 s 4.4, the insurer must demonstrate that the injury no longer meets the 'threshold injury' criteria. If the claimant's medical records show ongoing symptoms, the insurer's refusal may be challenged by providing updated assessments.
When to Seek Legal Advice
Treatment providers and claimants should consult a solicitor if:
- The insurer refuses to cover a treatment deemed 'reasonably necessary' by medical professionals
- The claimant's injury appears to meet the 'threshold injury' criteria but is excluded from benefits
- The insurer's refusal to review a claim exceeds the 28-day deadline
Legal professionals can help challenge decisions that appear to contradict SIRA guidelines or the Motor Accident Injuries Act 2017. They can also assist with preparing evidence for the Personal Injury Commission's medical dispute pathway.
