I'm working CCI edits for a hospital so this is for technical not professional. Is it appropriate to add modifier 59 to the drug admin code '96374' when on the same claim as the blood transfusion '36430' if the drugs given are to pre-treat for the blood (e.g., diphenhydramine 50mg). These drugs are of course not administered during the blood transfusion. In our system I can see the drug documentation but I'm unable to see the blood transfusion documentation. Is it even necessary to see the blood infusion doc. when we get these particular edits?
