Understanding Medical Assessment Disputes in NSW CTP Claims
If you have been injured in a motor accident in Greater Sydney and your insurer disputes the medical evidence used to assess your injury, you may be involved in a medical assessment dispute. These disputes typically arise when the insurer’s independent medical assessment (IMA) differs from your treating practitioner’s findings. The insurer’s assessment of liability in such cases is not based on fault alone, but on the medical evidence and how it aligns with the Motor Accident Injuries Act 2017 (MAIA). This means that even if you were not at fault, the insurer may challenge the extent or nature of your injury based on the medical report. The outcome of the dispute can affect your access to statutory benefits, treatment and care, and potentially your entitlement to damages.
How Insurers Evaluate Medical Evidence in Disputes
Insurers assess liability in medical assessment disputes by comparing the medical evidence provided by your treating medical practitioner with an independent assessment conducted under the Motor Accident Injuries Act 2017. The insurer may request an IMA from a medical practitioner approved by the Personal Injury Commission (PIC). This assessment must follow the Motor Accident Guidelines, which set out the standards for evaluating injuries such as whiplash, back injuries, and other soft tissue injuries. The insurer will review whether the injury is consistent with the accident, whether it meets the threshold for a permanent impairment, and whether it is likely to result in long-term consequences.
The insurer’s decision on liability in a dispute is not final. It is based on a review of medical records, diagnostic imaging, clinical findings, and the treating practitioner’s opinion. If the insurer finds that the injury is not supported by objective evidence or does not meet the criteria for a threshold injury under the Guidelines, they may refuse to pay for treatment, weekly income payments, or damages. This assessment is not a determination of fault, but a review of medical causation and severity.
The Role of the Personal Injury Commission (PIC) and SIRA Guidelines
The Personal Injury Commission (PIC) is the body responsible for resolving medical assessment disputes in NSW. If a dispute arises, either you or the insurer can request a review through the PIC’s formal dispute resolution pathway. The PIC will assess whether the medical evidence supports the claim and whether the assessment complies with the Motor Accident Guidelines. The Guidelines are binding on all parties and require that medical assessments be conducted by qualified practitioners using accepted clinical standards.
Under the MAIA, a medical assessment must demonstrate a clear link between the accident and the injury. For example, a spinal nerve-root injury that causes neurological signs such as muscle weakness or altered sensation may still be considered a soft-tissue injury under the Guidelines, even if it does not involve radiculopathy. However, radiculopathy, characterised by pain radiating along a nerve pathway, requires specific clinical signs to be recognised as a threshold injury. Insurers rely on these distinctions when evaluating whether an injury qualifies for statutory benefits or damages.
Practical Steps to Resolve a Medical Assessment Dispute
If your insurer disputes your medical assessment, you should act promptly. Gather and preserve all medical evidence, including reports from your treating practitioner, diagnostic imaging (X-rays, MRIs), and records of treatment. Keep copies of correspondence with the insurer, including any letters stating their reasons for disputing the assessment. You may also request a copy of the insurer’s independent medical assessment report, if it has been completed.
You can initiate a dispute resolution process through the PIC by submitting a formal request. This process is free and does not require legal representation. The PIC will review the evidence and may request further information or arrange for a second opinion. The review process typically takes several weeks, and you will be notified of the outcome in writing. If the PIC upholds your assessment, the insurer must accept the findings and provide any benefits that were previously denied.
A key point is that challenging a medical assessment does not guarantee a change in decision. The PIC will assess whether the medical evidence supports your claim under the Guidelines. If the evidence is weak or inconsistent, the PIC may uphold the insurer’s position. Therefore, it is essential to ensure that your medical records are accurate, complete, and clearly link your injury to the accident.
Time Limits and When to Seek Advice
There are time limits that apply to medical assessment disputes. You must notify the insurer of your intention to dispute the assessment within 28 days of receiving their decision. If you miss this deadline, you may lose the right to challenge the assessment through the PIC. The insurer must also respond to a dispute within 28 days of receiving it, or the dispute may proceed automatically.
If you are unsure about the medical evidence, the dispute process, or your rights under the MAIA, you should seek independent legal advice. A solicitor experienced in motor accident claims can help you understand whether your injury meets the threshold for benefits, whether the insurer’s assessment was properly conducted, and whether you have grounds to appeal. The decision to dispute a medical assessment should not be made lightly, as it may affect your access to treatment and financial support.
Hypothetical Example: A Disputed Soft-Tissue Injury
Consider a case where a driver in Sydney was involved in a low-speed rear-end collision. The driver reported neck and back pain and was assessed by a physiotherapist and a general practitioner, who diagnosed a soft-tissue injury. The insurer commissioned an IMA, which concluded that no injury was present, citing a lack of objective signs on MRI and no clinical evidence of nerve involvement. The driver disputed this and requested a PIC review. The PIC examined the full medical record, including the treating practitioner’s notes and imaging, and found that the driver had objective signs of muscle spasm and restricted movement consistent with a soft-tissue injury. The PIC ruled in favour of the driver, and the insurer was required to provide treatment and care benefits.
This example illustrates how medical evidence, not fault, determines entitlement in a CTP claim. It also shows that a dispute can be resolved in favour of the claimant when the evidence supports the injury.
