Current as at 18 August 2026

How CTP Insurers Investigate Treatment Funding Requests

New South Wales Compulsory Third Party (CTP) insurers may conduct surveillance to assess whether treatment costs claimed by injured parties are legitimate and related to the motor accident. This process involves reviewing medical records, treatment plans, and other evidence to determine if the claimed expenses meet the legal criteria for funding under the Motor Accident Injuries Act 2017.

Insurers may investigate treatment funding requests by:

  • Requesting detailed medical reports and treatment records
  • Assessing the necessity of specific therapies or procedures
  • Verifying that treatment costs are directly linked to the accident
  • Reviewing correspondence with healthcare providers
  • Conducting site visits or interviews with claimants

These investigations aim to ensure that funding decisions align with SIRA guidelines and legal requirements. Claimants should be aware that insurers have a duty to act reasonably during this process.

SIRA Guidelines on Insurer Surveillance

The State Insurance Regulatory Authority (SIRA) oversees CTP claims in NSW and provides authoritative guidance on insurer conduct. Key principles include:

1. Reasonable Surveillance Practices

SIRA expects insurers to conduct surveillance in a way that is:

  • Proportionate to the claim's complexity
  • Based on objective evidence
  • Compliant with the Motor Accident Guidelines

Insurers must avoid intrusive or unreasonable methods, such as requesting unnecessary personal information or using surveillance to challenge legitimate treatment needs.

2. Funding Criteria for Treatment Costs

To qualify for funding, treatment must:

  • Be directly related to the motor accident injury
  • Be medically necessary and reasonable
  • Be provided by an approved healthcare provider

Insurers may request documentation such as:

  • Doctor's notes confirming treatment necessity
  • Itemized bills from healthcare providers
  • Evidence of prior medical advice supporting the treatment plan

Practical Steps for Claimants in Ashfield

If you're in Ashfield and dealing with a CTP claim, consider these steps:

1. Document All Treatment Details

Keep records of:

  • All medical appointments and treatments
  • Correspondence with your treating physician
  • Receipts for treatment-related expenses
  • Notes from consultations about your injury

2. Understand the 52-Week Rule

Under the Motor Accident Injuries Act 2017, weekly benefits and treatment costs are generally limited after 52 weeks if your injuries are classified as 'threshold injuries' (soft tissue injuries meeting specific medical criteria). This rule applies only if your injuries are your 'only injuries' from the accident.

3. Respond to Insurer Requests

Cooperate with insurers by:

  • Providing requested documentation promptly
  • Clarifying any ambiguities in your records
  • Seeking legal advice if you believe an investigation is unreasonable

4. Know When to Seek Legal Help

Consult a legal professional if:

  • You're unsure whether your treatment costs qualify for funding
  • You believe an insurer's investigation is overstepping its authority
  • You receive a decision that you disagree with

Example Scenario: Surveillance and Funding Dispute

Imagine a claimant in Ashfield who sustained a soft tissue injury in a car accident. The insurer requests detailed medical records to assess the injury's severity. The claimant provides a doctor's note confirming the injury meets the threshold injury criteria. However, the insurer later disputes the funding of physiotherapy sessions, arguing they are not 'necessary' under the guidelines. In this case, the claimant may need to:

  1. Obtain a second medical opinion confirming the treatment's necessity
  2. Submit additional documentation showing the treatment's direct link to the injury
  3. Seek legal advice to challenge the insurer's decision

Next Steps for Claimants

CTP insurers have legal obligations to act reasonably during surveillance investigations. However, claimants should be prepared to provide clear evidence supporting their treatment costs. If you're in Ashfield and facing difficulties with your CTP claim, consider:
