I understand that the e/m would be included with the observation code, but what if one Dr does e/m visit and then another Dr, same group, does the observation? I have done cci edits on the 2 codes and a modifier is allowed on 9928* but was looking for examples of this. I need to know if it's allowed for same Dr, both codes or if it would be applied if there were 2 different Dr's involved. Any help would be great.
