You cannot just add modifiers to get charges paid. You will get yourself into hot water that way. It sounds as if you are the biller, not the coder. The claim should come over coded complete with modifiers. There are modifiers to indicate that procedures are separate but without knowing all details or seeing the patient's chart it would be impossible to tell you if they would be appropriate. You can google "modifiers for cpt codes" to view a list if you don't have one. They are also posted in the cpt books.
