If an insurer in New South Wales is preparing for medical assessments as part of your Compulsory Third Party (CTP) claim, you may have concerns about how the process is handled. This article explains how to challenge insurer practices under the NSW CTP scheme, including how to raise complaints with the State Insurance Regulatory Authority (SIRA). It covers the legal framework, evidence needed, and steps to dispute medical assessment decisions.

What Are the Rules Behind SIRA Insurer Complaints?

Under the Motor Accident Injuries Act 2017, insurers must act fairly when assessing claims. SIRA oversees compliance with these rules, including how insurers handle medical assessments. If you believe an insurer is acting unreasonably during a medical assessment, you can raise a complaint with SIRA. The insurer must first address your concerns internally before SIRA intervenes. SIRA’s guidelines state that complaints should focus on whether the insurer’s actions meet the legal standards for fairness and transparency.

Practical Steps to Challenge Medical Assessments

To challenge an insurer’s medical assessment practices, follow these steps:

  • Document the process: Keep records of all communication with the insurer, including dates, times, and details of medical assessments.
  • Request an internal review: Before lodging a complaint with SIRA, ask the insurer to review its decision. This is a legal requirement under the CTP scheme.
  • Lodge a complaint with SIRA: Use SIRA’s online complaint form or contact them directly. Your complaint should explain why you believe the insurer’s actions were unfair, such as refusing to cover necessary treatments or misinterpreting medical evidence.
  • Provide medical evidence: Include copies of medical reports, treatment records, and any correspondence with healthcare providers to support your claim.

When challenging an insurer, it’s important to know that SIRA will assess whether the insurer’s actions align with the CTP scheme’s rules. For example, if an insurer refuses to cover a treatment recommended by your doctor, you must show that the treatment is reasonable and necessary under the Motor Accident Guidelines.

Time Limits and Dispute Options

You have 52 weeks from the date of your accident to claim certain benefits under the CTP scheme. If your claim involves disputes over medical assessments, you must act within this timeframe. If the insurer’s decision affects your ability to receive weekly payments or treatment benefits, you should escalate the issue promptly.

If your complaint with SIRA is unresolved, you may need to seek independent legal advice. While SIRA does not provide legal representation, a solicitor can help you explore options such as mediation or formal dispute resolution. Remember, challenging an insurer’s medical assessment does not guarantee a change in their decision, SIRA will assess whether the insurer’s actions were legally compliant.

Example Scenario

Consider a claimant who was in a car accident and later received a medical assessment from the insurer. The claimant’s doctor later provided additional evidence showing the injury was more severe than initially assessed. The insurer refused to update the claim based on the new evidence. In this case, the claimant could challenge the insurer by submitting the updated medical records to SIRA and requesting a review of the assessment process.

When to Seek Advice

If you are unsure whether an insurer’s actions meet the legal standards for CTP claims, or if your complaint with SIRA is not resolved, it’s advisable to consult a legal professional. A solicitor can help you understand your options and ensure your rights under the CTP scheme are protected.
