Our coding dept is being requested to bill out a UA with a 99211. I know as it is an E&M I can add a 25 modifier. I am having trouble with this because of the UA having its own CPT code and by my understanding of E&Ms you can only bill both if there is a separate reason for the E&M service. Is there a documented reason and a coding guideline for not being able to do this? I am just wanting to make sure we are not doing something that would cause red flags or repercussions along the way. I have received one answer from another thread but that did not satisfy my manager. I am hoping for more information.

Thanks so much, in advance
