Question:
Surgery of Primary Site--Breast: Does the presence of axillary lymph node(s) in a "simple mastectomy" specimen impact the coding of the Surgery of Primary Site field for breast primaries?
Discussion:
Answer:
Yes. Determine whether there is, in fact, at least a portion of axillary tissue present. If axillary lymph nodes (not internal mammary nodes) are present in the specimen, code the Surgery of Primary Site field to 51 [Modified Radical Mastectomy WITHOUT removal of uninvolved contralateral breast]. If there are no axillary lymph nodes present in the specimen, code the Surgery to Primary Site field to 41 [Total (simple) mastectomy WITHOUT removal of uninvolved contralateral breast].
