Why Insurers May Change an Assessor for a CTP Claim

In New South Wales, insurers managing Compulsory Third Party (CTP) claims must follow strict guidelines when assessing injuries. A change in assessor is often triggered by discrepancies in initial findings, new medical evidence, or perceived conflicts of interest. Under the Motor Accident Injuries Act 2017, insurers have a duty to ensure assessments are fair and based on objective medical evidence. If an insurer replaces an assessor, it must provide a clear reason, such as a conflict of interest or a need for a second opinion.

Your Rights When an Assessor is Changed

Claimants have the right to understand the reasoning behind an assessor change and to challenge decisions that affect their benefits. Under SIRA guidelines, insurers must notify claimants of any changes and provide access to all relevant documentation. If you believe the change is unjustified or impacts your claim unfairly, you can request a formal review or seek mediation through the NSW Civil and Administrative Tribunal (NCAT). It is crucial to document all communications and retain copies of any new evidence submitted.

How to Challenge an Insurer’s Decision

To challenge an assessor change, start by reviewing the insurer’s written explanation. If the change appears arbitrary or based on incomplete information, you may:

  • Request a detailed written explanation of the new assessor’s findings
  • Submit additional medical evidence to support your claim
  • Seek independent medical opinion to verify the assessment
  • Lodge a formal dispute with the insurer’s internal review process

If the insurer refuses to reconsider, you can escalate the matter to NCAT. Under the Motor Accident Injuries Act 2017, claimants have the right to contest decisions that affect their weekly benefits, treatment and care payments, or long-term impairment assessments.

SIRA’s Guidance on Assessor Changes

SIRA’s Motor Accident Claims page outlines that insurers must ensure assessments are based on the 'best available evidence' and that claimants are informed of any changes. While SIRA does not explicitly address assessor changes in its guidelines, its emphasis on transparency and fairness implies that insurers must justify any replacement of an assessor. Claimants should also be aware that repeated changes without clear justification may indicate procedural irregularities.

Practical Steps to Take

  1. Request written documentation of the assessor change, including the reason provided by the insurer.
  2. Review all medical records to ensure they are complete and have been shared with the new assessor.
  3. Keep copies of all correspondence with the insurer, including emails and letters.
  4. Seek independent medical advice if you believe the new assessment is inaccurate.
  5. Consult a legal professional if the insurer’s actions appear to breach the Motor Accident Injuries Act 2017.

When to Seek Legal Advice

If the insurer’s decision to change assessors results in a reduction or denial of benefits, or if you are unsure about your rights, it is advisable to seek legal assistance. A solicitor can help you:

  • Challenge the insurer’s decision through formal dispute processes
  • Ensure your claim complies with SIRA guidelines
  • Navigate the NCAT process if necessary

Final Considerations

CTP insurers must follow specific legal frameworks when managing claims, and changes to assessors must be justified under these rules. While insurers have the authority to replace assessors in certain circumstances, claimants have the right to challenge decisions that affect their benefits. By understanding your rights and following the correct procedures, you can protect your claim and ensure fair treatment under NSW law.
