Our general surgeon performed a radical mastectomy and is now performing a port placement, at a separate session, for the patient. What modifier should we use on the port placement since both procedures are related to her diagnosis of breast cancer?
Although the diagnosis for each procedure is breast cancer, the procedures themselves are unrelated, so modifier 79 Unrelated Procedure during a global period is the correct modifier.
