Permanent Impairment Threshold and Caregiver Claims in NSW

If you're a caregiver for someone injured in a motor accident in New South Wales, understanding the permanent impairment threshold is critical. Under the Motor Accident Injuries Act 2017, a person must have at least a 10% whole person impairment to qualify for certain benefits. This threshold determines whether you, as a family member, can claim compensation for caregiving costs, lost income, or other dependant-related expenses.

How the Impairment Threshold Affects Caregiver Claims

The 10% threshold is defined by the Motor Accident Guidelines, which require specific clinical signs such as neurological deficits or functional limitations. If the injury meets this threshold, you may be eligible for:

  • Weekly income payments for the injured person
  • Treatment and care benefits for dependants
  • Compensation for lost income if you had to reduce work hours

However, if the injury is below the threshold (e.g., soft tissue injuries without neurological signs), caregivers typically cannot claim financial support. This distinction is crucial for families on the Central Coast, where medical assessments must clearly document impairment levels.

Practical Steps for Families on the Central Coast

To support your claim, gather:

  • Medical reports confirming the 10% impairment threshold
  • Evidence of caregiving hours (e.g., diary entries, employer records)
  • Proof of your income and how caregiving impacted it
  • Accident details from police reports or witnesses

Consult a medical practitioner to ensure your injury meets the threshold. SIRA (State Insurance Regulatory Authority) uses these guidelines to assess claims, so accurate documentation is essential.

Time Limits and Dispute Resolution

You have 52 weeks from the accident date to claim certain benefits if the injury is below the threshold. For threshold injuries, benefits are generally limited after 52 weeks unless the injury is permanent. If your claim is disputed, you may need to:

  1. Request a medical review by an independent assessor
  2. Submit additional evidence to SIRA
  3. Seek legal advice if the insurer rejects your claim

When to Seek Professional Help

Families should consult a solicitor if:

  • The injured person’s impairment is unclear
  • Caregiving costs are significant
  • The insurer denies claims without explanation
  • The accident occurred on private property or a car park (as these may require special assessment)

Summary of Key Considerations

The 10% impairment threshold determines whether caregivers can claim financial support. Families on the Central Coast must ensure medical evidence clearly documents the injury’s severity. Time limits apply, and disputes may require expert review. Always seek legal advice if your claim is rejected or if you need guidance on caregiving costs.
