How NSW CTP Claims Assess Permanent Impairment Thresholds

If you're recovering from a motor accident injury on the Central Coast and struggling to return to daily activities, understanding the permanent impairment threshold is critical. Under NSW law, injuries must meet the 10% whole person impairment threshold to qualify for certain compensation benefits. This article explains how SIRA evaluates daily activity limitations, what evidence is needed, and how the threshold applies to your claim.

What Is the Permanent Impairment Threshold?

The permanent impairment threshold is defined in the Motor Accident Injuries Act 2017. It means an injury must result in a 10% or greater whole person impairment to qualify for specific benefits. This threshold determines whether you're eligible for weekly income payments, treatment and care benefits, or compensation for permanent impairment. SIRA uses the Motor Accident Guidelines to assess whether your injury meets this standard.

How SIRA Assesses Daily Activity Limitations

SIRA evaluates how your injury affects your ability to perform everyday tasks, such as work, household chores, or personal care. Medical evidence is essential. Doctors must document how your injury limits your daily activities and whether it meets the 10% impairment threshold. For example, if your injury prevents you from working full-time or requires ongoing assistance with mobility, this may support a claim.

Evidence Required for CTP Claims

To prove your injury meets the threshold, you'll need:

  • Detailed medical records showing the nature and severity of your injury
  • A report from a medical practitioner assessing your daily activity limitations
  • Evidence of how your injury impacts your ability to work or perform routine tasks
  • Accident reports or witness statements if your injury resulted from a collision

Time Limits and Dispute Options

You have 52 weeks from the date of your injury to claim certain benefits under the CTP scheme. After this period, weekly payments and treatment benefits generally stop unless your injury is classified as a permanent impairment. If your claim is disputed, SIRA may request additional medical evidence or refer the matter to a medical expert.

When to Seek Legal Advice

If your injury is severe and you're unsure whether it meets the 10% threshold, or if you're facing a dispute with SIRA, it's important to seek legal advice. A solicitor can help you understand your options, ensure all evidence is properly submitted, and challenge decisions that may unfairly limit your benefits.

Next Steps

The available options depend on the date of your accident, the nature of your injury, and how your daily activities are affected. To request contact about your circumstances, complete the quick, no obligation enquiry form.
