I am not sure which guidelines you are referring to but there is only one set of official guidelines. The following is an excerpt from these guidelines:
From Section I under screening it says:
Should a condition be discovered during the screening then the code for the condition may be assigned as an additional diagnosis.
Not to get into the middle of this one, because I do believe that each opinion is validated, but doesn't the "may be" in that quote from the guidelines constitute a decision by the coder to do so? It doesn't seem like it is mandated in that statement. For us here, we use the V code for Medicare and BX but for everyone else, we use the 211.3 code. I am not trying to make waves, I am legitamitely confused by all of this. Do you follow the "surgery" guidelines or do you follow the "screening" guidelines? We are also CAH so our case proably doesn't apply to all.
In the end, I guess I also agree with Gloria that since even the "big wigs" can't agree, we do what we have to, individually, to code what we believe to be "to the best of our ability".
