Get all the anesthesia resources you need from one online solution. The Anesthesia Expert online tool combines American Society of Anesthesiologists (ASA) coding resources (ASA CROSSWALK, ASA Reverse CROSSWALK, Relative Value Guide) and an anesthesia fee calculator. The fee schedule feature allows you to calculate the anesthesia fee by inputting the anesthesia start and stop times, physical status modifiers, varied time units, and geographic location. The fee calculator also allows you to choose between QP and non-QP conversion factors.
