How the 10% Impairment Threshold Affects Treatment Funding in NSW CTP Claims

If you've suffered a motor accident in Ballina and are seeking treatment funding through NSW's Compulsory Third Party (CTP) scheme, understanding the permanent impairment threshold is critical. Under the Motor Accident Injuries Act 2017, a claimant must have a whole person impairment of at least 10% to qualify for ongoing treatment costs. This threshold determines whether you're eligible for weekly income payments or long-term care funding.

NSW CTP Rules Behind Treatment Funding

The CTP scheme covers treatment costs only if your injury meets the 10% impairment threshold. SIRA (State Insurance Regulatory Authority) assesses claims using the Motor Accident Guidelines, which define impairment based on clinical evidence. For example, a spinal nerve-root injury with neurological signs may qualify, while radiculopathy requires specific clinical signs under the guidelines.

If your injury is below the threshold, you may still receive treatment benefits for up to 52 weeks, but funding for ongoing care is limited. The scheme prioritizes claims where the injury significantly impacts daily living, such as mobility or cognitive function.

Proving Your Case in Ballina

To claim treatment funding, you must provide:

  • A medical report confirming your impairment meets the 10% threshold
  • Evidence of treatment costs (e.g., invoices, prescriptions)
  • Details of how the injury affects your daily activities

SIRA may request additional documentation, such as a specialist's opinion or a rehabilitation plan. If your claim is denied, you can request a review by submitting new evidence or disputing the impairment assessment.

Time Limits and Dispute Options

You have 52 weeks from the accident date to claim treatment benefits under the threshold. After this period, you may need to pursue a common law damages claim, which requires proving fault and a higher impairment level. Disputes over the threshold are resolved through SIRA's internal review process, not the courts.

When to Seek Legal Advice

If your injury involves complex issues like spinal nerve damage or cognitive impairment, consult a solicitor to ensure your claim meets the threshold. A lawyer can also help if SIRA disputes the severity of your injury or the cost of treatment.

Next Steps

CTP funding depends on the date of your accident, the nature of your injury, and the evidence you provide. To discuss your circumstances, complete the quick, no obligation enquiry form. Every claim depends on its own facts.
