How Insurers Assess Psychological Treatment Plans in NSW CTP Claims

If you have suffered a psychological injury in a motor accident in Greater Sydney and are seeking approval for a psychological treatment plan under NSW Compulsory Third Party (CTP) insurance, you may receive a decision from your insurer that limits, delays or denies coverage. Insurers assess these plans based on the Motor Accident Injuries Act 2017 (MAIA) and the Motor Accident Injuries Regulation 2017, which set out the legal framework for treatment and care benefits. These laws require that any treatment plan must be necessary, reasonable and directly related to injuries resulting from the accident. Insurers will review whether the proposed treatment is clinically appropriate, evidence-based and aligned with the Motor Accident Guidelines, which provide standards for mental health assessments and interventions.

What Factors Influence Insurer Decisions

Insurers consider several factors when reviewing a psychological treatment plan. First, they assess whether the psychological injury is recognised under the MAIA as a compensable injury. This includes conditions such as post-traumatic stress disorder (PTSD), anxiety, depression or adjustment disorder, provided they are directly linked to the accident. The insurer will examine medical evidence, including reports from a treating psychologist or psychiatrist, to confirm the diagnosis and establish a causal connection to the motor accident.

Second, the insurer evaluates whether the treatment plan is proportionate and consistent with best practice. For example, a plan that includes cognitive behavioural therapy (CBT), trauma-focused therapy or medication management may be approved if supported by clinical guidelines. The insurer may request a second opinion or ask for a treatment plan that includes measurable goals and timelines. They may also assess whether the treatment provider is registered with the Psychology Board of Australia and whether the treatment is being delivered by a qualified mental health professional.

Third, the insurer will consider whether the treatment is being provided in a timely manner. Delays in starting treatment, particularly where symptoms have persisted for more than 12 weeks, may result in a request for further evidence to substantiate the need for intervention. Insurers may also review whether the claimant has previously accessed mental health services, as this can affect the assessment of whether the current condition is new or exacerbated by the accident.

Practical Steps to Support Your Claim

To strengthen your position when challenging an insurer’s decision, gather and preserve the following evidence:

  • A detailed clinical report from your treating psychologist or psychiatrist, including diagnostic criteria, symptom duration and functional impact.
  • A written treatment plan outlining the type of therapy, frequency, duration and expected outcomes.
  • Records of any prior mental health treatment, including dates, diagnoses and interventions.
  • Photographs of the accident scene, if relevant to trauma triggers.
  • Witness statements, if others observed your mental health decline following the accident.
  • Correspondence with your insurer, including any letters, emails or call logs.

If your insurer denies or limits approval for a psychological treatment plan, you may request a review of the decision. This can be done by submitting a formal written request to the insurer, including any new evidence that supports the need for treatment. You may also contact the Motor Accident Injury Scheme (MAIS) through the State Insurance Regulatory Authority (SIRA) for assistance in resolving disputes.

Time Limits and Dispute Options

There is no fixed deadline for requesting a psychological treatment plan under the CTP scheme, but delays in reporting or seeking treatment may affect the insurer’s assessment of causation. If you have not received a response to your request within 28 days, you may escalate the matter to SIRA. You may also apply to the Civil and Administrative Tribunal (NCAT) for a determination on the approval of treatment, particularly if the insurer continues to deny coverage despite medical evidence.

If you believe your insurer has acted unfairly or failed to follow the MAIA, you may seek independent advice from a legal practitioner or a consumer advocacy service. SIRA provides information on dispute resolution pathways, including mediation and formal applications to NCAT. These processes are designed to ensure that claimants receive fair consideration of their treatment needs under the law.

Hypothetical Example: A Case from Greater Sydney

A 38-year-old woman was a passenger in a car that was struck from behind in a rear-end collision in Sydney’s Northern Beaches. She experienced acute anxiety, sleep disturbances and intrusive thoughts about the crash. Her treating psychologist diagnosed her with PTSD and submitted a treatment plan for 12 weekly CBT sessions. The insurer initially declined approval, stating that the symptoms were not severe enough to warrant treatment. After the claimant submitted a detailed report from her psychologist, including a functional assessment and a history of no prior mental health issues, the insurer approved the plan. This example illustrates how medical evidence and a properly structured treatment plan can influence insurer decisions.
