Economic loss claims under NSW Compulsory Third Party (CTP) laws cover treatment costs related to lost income and financial losses after a motor accident. This article explains how SIRA guidelines determine funding for these costs, outlines eligible expenses, and provides practical steps for claimants in Greater Sydney. Time limits and dispute resolution options are also addressed.

What Treatment Costs Are Covered in Economic Loss Claims?

Economic loss claims under the Motor Accident Injuries Act 2017 (MAIA) fund treatment costs directly tied to financial losses, not physical injuries. This includes:

  • Medical bills for treatments necessary to address injuries causing lost income
  • Rehabilitation costs to restore earning capacity
  • Travel expenses related to treatment
  • Lost wages during recovery periods

These costs are distinct from impairment-based claims, which focus on physical injuries. Economic loss claims specifically address financial impacts, such as reduced earning capacity or job loss due to an accident.

How SIRA Determines Funding for Treatment Costs

SIRA (State Insurance Regulatory Authority) assesses treatment costs based on:

  1. Medical necessity: Treatment must be clinically necessary to address the injury's impact on earning capacity.
  2. Direct financial loss: Costs must directly relate to lost income or financial harm. For example, a physiotherapist's fees for a worker recovering from a back injury that prevents them from lifting heavy objects would qualify.
  3. Documentation: Claimants must provide medical records, invoices, and evidence linking treatment to financial loss. SIRA uses its Motor Accident Guidelines to evaluate whether the treatment is reasonable and necessary.

A hypothetical example: After a car accident, a nurse loses 12 weeks of income due to a shoulder injury. SIRA would fund physiotherapy costs to restore her ability to lift patients, as the treatment directly addresses the financial loss of reduced earning capacity.

Practical Steps to Ensure Funding

To secure funding for treatment costs under an economic loss claim:

  • Document all treatment costs: Keep receipts, medical reports, and correspondence with healthcare providers.
  • Link treatment to financial loss: Work with a medical expert to show how the treatment addresses the injury's impact on income. For instance, a psychologist's fees for a claimant with anxiety that prevents them from working would need to be tied to lost wages.
  • Notify the insurer: Inform the at-fault driver's insurer about all treatment costs and financial losses. Delays in notification may affect funding.
  • Seek independent medical reports: If the insurer disputes the necessity of treatment, a second opinion from a specialist may be required.

Time Limits and Dispute Resolution

Economic loss claims must be made within the legal time limits for CTP claims. While the MAIA 2017 does not specify a fixed deadline for economic loss claims, delays can reduce the chances of securing funding. If the insurer disputes the claim, claimants may need to:

  • Request a review of the insurer's decision
  • Seek mediation through SIRA
  • Consult a legal professional to challenge the decision

When to Seek Legal Advice

Claimants should seek legal assistance if:

  • The insurer refuses to fund necessary treatment
  • There are disputes over the link between treatment and financial loss
  • The claimant is unsure whether their circumstances qualify for economic loss funding

Next Steps

Economic loss claims require careful documentation and a clear connection between treatment and financial harm. While SIRA provides a framework for funding, the process can be complex. Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
