How NSW CTP Insurers Assess Liability for Psychological Treatment Plans (Central Coast)

How NSW CTP Insurers Assess Liability for Psychological Treatment Plans

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).

NSW CTP insurers evaluate psychological treatment plans by assessing whether the injury is a 'threshold injury' under the Motor Accident Injuries Act 2017 and whether the treatment is medically necessary and directly related to the accident. Psychological injuries, such as anxiety or post-traumatic stress, are treated under the same statutory framework as physical injuries, but insurers scrutinise the connection between the accident and the mental health condition.

Legal Framework for Psychological Claims

Under the Motor Accident Guidelines, a 'threshold injury' includes injuries that result in a 'significant and lasting' impairment, which may involve psychological symptoms. Insurers must determine if the treatment plan addresses a threshold injury, not just a minor or temporary issue. For example, a psychologist's report must specify how the accident triggered the psychological condition and why ongoing therapy is required.

The Motor Accident Injuries Act 2017 s 4.4 limits benefits for injuries that do not meet the threshold criteria. If a claimant's injuries are below this threshold, insurers may refuse to cover treatment beyond 52 weeks, unless the treatment is for a non-threshold injury. This distinction is critical for psychological claims, as insurers often debate whether anxiety or depression qualifies as a threshold injury.

Evidence Required for Psychological Treatment Claims

Insurers require detailed evidence to support a psychological treatment plan, including:

  • A psychologist's report linking the injury to the accident
  • Medical records showing a diagnosis of a threshold injury
  • Documentation of treatment duration, frequency, and cost
  • Evidence that the treatment is not for a pre-existing condition

For instance, if a claimant developed anxiety after a car accident, the psychologist must explain how the accident caused the condition, not pre-existing stressors. Insurers may also request a 'treatment and care' plan under the Motor Accident Guidelines to assess the necessity of ongoing therapy.

Time Limits and Dispute Resolution

Claimants must notify their insurer within 52 weeks of the accident to claim statutory benefits for injuries that do not meet the threshold criteria. However, if the injury is a threshold injury, the 52-week limit does not apply. Insurers may dispute the validity of a psychological treatment plan, requiring claimants to provide additional evidence or seek a review.

If an insurer refuses to approve a treatment plan, claimants can request a review through the NSW Civil and Administrative Tribunal (NCAT) or seek independent medical opinions. It is essential to act promptly, as delays may jeopardise eligibility for benefits.

When to Seek Legal Advice

Insurers often challenge the connection between an accident and psychological injuries, especially if the claimant has a history of mental health issues. A solicitor can help navigate disputes, ensure all evidence is properly submitted, and challenge decisions that appear to disregard the claimant's needs. Legal advice is particularly valuable when insurers dispute the threshold injury status or refuse to cover long-term treatment.

Next Steps

CTP insurers assess psychological treatment plans based on strict legal criteria. Understanding the threshold injury rules, gathering comprehensive evidence, and acting within time limits are crucial.
