Hope someone can help with some input on this one. Where I work we often do wound vac's on patients after major open heart/chest surgery. I would code the vac changes as 15852 -58, but now I am unsure about the modifier. They do not always go back to the operating room to have the procedure done, so should I be using the 58 modifier when they do not go to the operating room and 78 when they do go back to the operating room. I think I got confused because modifer 78 states "unplanned" and with wound vac's it is "planned" that they change them. Can anyone give me some useful insight on this topic?
