Understanding Psychological Treatment Plans in NSW CTP Claims
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).
A psychological treatment plan is a formal document prepared by a registered mental health professional that outlines the diagnosis, recommended treatment, and expected outcomes for a psychological injury resulting from a motor accident in New South Wales. Under the Motor Accident Injuries Act 2017 (MAIA), such a plan may be required to access treatment and care benefits or to support a claim for damages. In Greater Sydney, as elsewhere in NSW, common mistakes in preparing or submitting these plans can delay or reduce entitlements. These mistakes often stem from misunderstanding the legal requirements, failing to meet documentation standards, or not aligning the plan with the insurer’s expectations under the SIRA guidelines.
Key Legal Requirements for Psychological Treatment Plans
The Motor Accident Injuries Act 2017 and the Motor Accident Injuries Regulation 2017 set the legal framework for CTP claims in NSW. A psychological treatment plan must be prepared by a qualified mental health practitioner and must include: a diagnosis consistent with the International Classification of Diseases (ICD-11); a description of the treatment to be provided; the expected duration of treatment; and a statement that the treatment is necessary because of injuries sustained in the motor accident. The plan must also reflect that the injury is not pre-existing or unrelated to the accident.
SIRA, the State Insurance Regulatory Authority, provides guidance that treatment plans must be clinically justified and not merely administrative. The plan must not be a generic template. It must be individualised to the claimant’s injury, symptoms, and treatment response. A plan that lacks clinical reasoning or relies on standardised language without personalisation may be rejected by the insurer or CTP insurer, which can delay access to treatment and impact the claim.
Common Mistakes to Avoid in Greater Sydney
In Greater Sydney, claimants and practitioners often make the following errors when preparing psychological treatment plans:
- Failing to clearly link the psychological injury to the motor accident. The plan must demonstrate that the symptoms began or worsened after the accident, supported by a clinical history and assessment.
- Using a treatment plan that is not updated to reflect changes in symptoms or treatment progress. A plan that remains unchanged for months, despite ongoing treatment, may be seen as outdated and not reflective of current need.
- Submitting a plan that does not include measurable treatment goals or progress markers. SIRA expects treatment plans to include objectives that can be reviewed and assessed over time, such as reducing anxiety symptoms by 30% over six weeks.
- Including treatment modalities that are not supported by evidence-based practice for the diagnosed condition. For example, recommending unproven therapies without clinical justification may result in the insurer refusing to fund them.
- Not obtaining a formal assessment of whole person impairment (WPI) from a qualified medical assessor before finalising a long-term treatment plan. Where a claimant seeks damages, a WPI assessment is required, and a treatment plan must be consistent with that assessment.
These errors are not merely procedural. They can result in a claim being delayed, benefits being denied, or a damages claim being challenged on the grounds of inadequate treatment planning.
Evidence That Matters in CTP Claims
To support a psychological treatment plan, claimants should preserve and provide the following evidence:
- A detailed clinical history from the mental health practitioner, including the onset of symptoms and any changes since the accident.
- Medical records from the treating practitioner, including notes from therapy sessions and any medication management.
- A copy of the treatment plan, signed and dated by the practitioner, with a clear statement that the treatment is necessary due to the motor accident.
- Evidence of treatment adherence, such as appointment logs, therapy worksheets, or progress reports.
- Where applicable, a report from a qualified medical assessor confirming the diagnosis and WPI, particularly if the claim seeks damages.
In Greater Sydney, where medical services are widely available, insurers may scrutinise treatment plans more closely than in regional areas. This makes accurate documentation and timely submission even more critical.
Time Limits and Dispute Resolution
There is no fixed deadline for submitting a psychological treatment plan under the MAIA, but delays may affect the timing of benefit payments. The insurer must respond within 28 days of receiving a claim, including any supporting documents such as a treatment plan. If the insurer refuses to fund treatment outlined in the plan, the claimant may request a review or apply to the Civil and Administrative Tribunal (NCAT) for a determination.
A common mistake is to begin treatment without formal approval from the insurer, especially for long-term or intensive therapy. While treatment may be provided under the insurer’s implied consent if it is urgent and necessary, the claimant must still submit the plan and seek formal approval to ensure funding eligibility.
If a dispute arises, SIRA advises that claimants should not alter or fabricate records to support a claim. Any changes to a treatment plan must be documented and justified. The insurer may request a review of the plan by an independent expert, which can delay the process.
When to Seek Independent Advice
A psychological treatment plan is not a legal document in itself, but it forms part of the evidence base for a CTP claim. If the claimant is unsure whether their plan meets the legal and procedural standards, or if the insurer has refused to fund treatment, it is advisable to seek independent advice from a qualified legal practitioner or claims assessor.
The decision to proceed with a damages claim, particularly for psychological injury, depends on whether the injury meets the threshold for damages under the MAIA. This includes a determination that the injury is not a minor injury (now referred to as a threshold injury) and that it has caused a permanent impairment or significant impact on daily life. A treatment plan that does not reflect these legal thresholds may not support a damages claim.
Practical Example
A claimant in Sydney’s inner west was involved in a rear-end collision in February 2025. They developed persistent anxiety and sleep disturbances and were referred to a clinical psychologist. The psychologist prepared a treatment plan that included cognitive behavioural therapy (CBT) over 12 weeks, with weekly sessions. However, the plan did not include a baseline assessment of symptoms, nor did it outline measurable outcomes. The insurer rejected the plan, citing insufficient clinical justification. After a review by a second psychologist, a revised plan was submitted with symptom tracking, progress markers, and a clear link to the accident. The insurer approved funding.
This example illustrates how a technically valid treatment plan can still be rejected if it lacks clinical depth and evidence-based structure.
