Workers compensation

A permanent impairment assessor is a registered medical practitioner trained to assess a worker's permanent impairment as a result of a work related injury or illness.

In brief

A permanent impairment assessor is a registered medical practitioner recognised as a specialist with qualifications, training and experience relevant to the specific body system or systems being assessed.

To provide services within the NSW workers compensation system, you must be a trained assessor of permanent impairment for each body system you intend to assess and be listed for each body system on the SIRA workers compensation website. You may be one of the worker’s treating specialists or you may be engaged on behalf of the worker, employer or insurer for the purposes of assessing the level of permanent impairment.

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

In assessing permanent impairment, the assessor must determine:

  • whether the worker's condition has resulted in impairment
  • whether the condition has reached maximum medical improvement
  • whether the impairment is permanent
  • the degree of permanent impairment that results from the injury
  • the proportion of permanent impairment due to any previous injury, pre-existing condition or abnormality.
