If we performed the bone imaging, whole body (78306) with the isotope (A9503), how would i put in the diagnosis codes?? I have C77.3, C50.412, & C79.51 given by the referring physician. Do I code the secondary malignant neoplasm of bone (C79.51) first since it is a bone imaging scan? Or do i still put the primary Malignant neoplasm first?
Help!!
