Understanding CTP Coverage for Chronic Regional Pain Syndrome in NSW
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).
Chronic regional pain syndrome (CRPS) following a motor vehicle accident in New South Wales may be covered under the Compulsory Third Party (CTP) insurance scheme. If the injury results from a road accident, the CTP scheme may fund treatment and care costs, including specialist pain management, physiotherapy, psychological support and medical assessments. This coverage applies regardless of fault, provided the claim is made within the applicable time limits and the injury is recognised under the Motor Accident Injuries Act 2017 (MAIA).
Legal Framework for Treatment Funding Under CTP
Under the MAIA, individuals injured in a motor accident may be entitled to treatment and care benefits for injuries that are not classified as threshold injuries. CRPS is not automatically a threshold injury, but it may be assessed as such depending on its severity and clinical presentation. The Motor Accident Guidelines define a threshold injury as one that causes a permanent impairment of at least 10% of the whole person, or a permanent loss of function, or a condition that significantly affects daily life. If CRPS does not meet these criteria, treatment and care benefits may continue beyond the initial 52-week period, subject to medical evidence and insurer approval.
Where a person’s only injuries are threshold injuries, weekly payments and treatment and care benefits are generally limited to 52 weeks under section 4.4 of the MAIA. However, if the CRPS is not a threshold injury, or if it co-occurs with non-threshold injuries, ongoing treatment funding may be available. The insurer must approve treatment plans, and the treatment must be deemed reasonable and necessary by a qualified medical practitioner.
Practical Steps for Claimants in Greater Sydney
To access funding for CRPS-related treatment in Greater Sydney, claimants should:
- Seek prompt medical assessment from a specialist in pain management or neurology. A diagnosis of CRPS must be supported by clinical evidence, including imaging, nerve conduction studies, and a documented treatment response.
- Notify the CTP insurer of the injury and treatment needs as soon as possible. The claim must be made within the time limits set out in the MAIA, which generally allow up to three years from the date of the accident.
- Provide the insurer with a detailed treatment plan from a medical practitioner, including the type of treatment, frequency, duration and expected outcomes.
- Keep records of all treatment sessions, prescriptions, travel to appointments, and correspondence with the insurer.
In Greater Sydney, claimants may access specialist pain clinics through the CTP scheme, including those located at Royal North Shore Hospital, Westmead Hospital, and Royal Prince Alfred Hospital. These facilities have established pathways for CTP-funded treatment, but approval must still be obtained from the insurer.
Evidence That Supports Treatment Funding
The following evidence is commonly required to secure CTP funding for CRPS treatment:
- A formal diagnosis of CRPS from a medical practitioner, supported by imaging (e.g. MRI, bone scan) and nerve testing.
- A treatment plan outlining the recommended interventions, such as nerve blocks, spinal cord stimulation, graded motor imagery, or cognitive behavioural therapy.
- Documentation of treatment response, including progress notes and functional assessments.
- Evidence of ongoing functional impairment, such as difficulty with mobility, daily tasks, or work capacity.
A claimant may also need to provide a statement from a treating physician confirming that the treatment is medically necessary and that alternative options have been considered.
Time Limits and Dispute Options
There is a three-year time limit from the date of the motor accident to make a claim for treatment and care benefits under the MAIA. If the claim is made after this period, the insurer may refuse it unless a court order permits it. The claimant must also notify the insurer of the injury within 28 days of becoming aware of it, although this requirement may be waived in some circumstances.
If the insurer refuses to fund a treatment, the claimant may request a review under the CTP scheme. If the review is unsuccessful, the claimant may apply to the NSW Civil and Administrative Tribunal (NCAT) for a decision. The tribunal may order the insurer to fund the treatment if it determines it is reasonable and necessary.
Hypothetical Example
A 38-year-old woman in Sydney’s Northern Beaches was involved in a rear-end collision in June 2024. She developed CRPS in her right leg, with severe pain, swelling and limited mobility. Her specialist diagnosed CRPS using MRI and sympathetic nervous system testing. She submitted a treatment plan to her CTP insurer, including six months of intensive physiotherapy, three nerve blocks, and psychological support. The insurer initially refused funding for the nerve blocks, citing cost. After a review and submission of additional medical evidence, the insurer approved the treatment. The woman received full funding for all recommended care under the CTP scheme.
When to Seek Independent Advice
The CTP scheme’s treatment funding rules are complex, particularly for long-term conditions like CRPS. Because the outcome depends on the nature of the injury, the medical evidence, and the insurer’s interpretation of the MAIA, claimants are encouraged to seek independent legal or medical advice if:
- The insurer refuses to fund treatment despite medical evidence.
- The claimant experiences a change in symptoms or functional capacity.
- The claimant is considering a damages claim, which may be possible if the injury exceeds the threshold or if there is a significant loss of income.
