OEM focuses on the interaction between work, the environment, and health. Physicians practicing OEM are expected to understand how to recognize, prevent, evaluate, diagnose, treat, and manage adverse health effects from workplace and environmental hazards. Thus, it is the position of ACOEM that OEM physicians do practice clinical medicine and therefore qualify for a full unrestricted medical license. This guidance statement is intended to help occupational and environmental medicine (OEM) physicians determine what type of medical license they should hold – a clinical or an administrative license. And what they should do if they are advised by their state licensing body to apply for an administrative license instead of a clinical license, and they disagree.
