An approved medical specialist (AMS) plays an important role in the Western Australian workers’ compensation scheme. An AMS assesses an injured worker’s degree of permanent whole of person impairment (PWPI) caused by workplace injuries. These assessments determine access to certain workers’ compensation entitlements by injured workers.
WorkCover WA may designate a person as an AMS if the person is a registered medical practitioner who WorkCover WA considers to be sufficiently trained in the use of WorkCover WA Guidelines and satisfies WorkCover WA’s eligibility criteria.
