Motor accidents

In brief

A permanent impairment assessment is used to measure how much permanent change has happened to the injured person’s body because of their injury.

Your assessment can involve medical assessments, reports and information about the person's injuries and recovery. You should consider all available evidence and be satisfied that there is:

  • an impairment arising from an injury caused by the accident
  • an injury to the part being assessed and that it was caused by the accident
  • an impairment as defined at clause 6.9 of the motor accident guidelines.

You should use the permanent impairment assessment examination checklist when documenting the clinical findings specific to the assessment of the spine, upper and lower extremity, and nervous system.

If you have a question about permanent impairment, email for a response within five working days.

Permanent impairment assessors must adhere to the motor accidents code of conduct and terms of appointment.

What can I do to get paid quickest?

To facilitate prompt payment, we suggest you:

  • include the appropriate service code/s with your invoice
  • issue the account in the form of a tax invoice and include the:
    • injured person’s name
    • date of accident
    • insurer’s reference/claim number
    • provider’s ABN, address and GST (if applicable)
  • send accounts directly to the CTP Green Slip insurer. It is difficult to ensure timely submission of accounts by other parties (for example, an injured person or their solicitor)
  • direct all enquiries about payment to the claims officer you have been dealing with.
