I have read so many different views on this and it appears this is a grey area. Do diagnostic testing such as x-rays, ekg and labs performed during an emergency room encounter count as additional work-up, managemnet options on MDM? It seems if you do count this it would inappropriately elevate 99285. Such as situations when someone would come to the ER with anxiety....testings performed and Ativan administered, or alcohol withdrawal and Librium administered. Does anyone have a reliable source of information on this.
