Answer:
Code the most extensive surgery in Surgery of Primary Site. This is a cumulative field. Assign the appropriate code including all surgeries of the primary site performed during the first course of treatment.
The correct code for mastectomy followed by re-excision will depend on the extent of the re-excision. For example, if the re-excision removed muscle, code radical mastectomy.
