Question:

Surgery of Primary Site/Scope Regional LN Surgery--Breast: How should these fields be coded when a sentinel lymph node dissection removes one-to-three axillary lymph nodes and a total/simple mastectomy is done?

Discussion:

Answer:

Assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast] for Surgery of Primary Site. Assign code 2 [Sentinel lymph node biopsy] for Scope of Regional Lymph Node surgery. Code 41 applies to a total/simple mastectomy with any number of sentinel lymph nodes removed -- as long as all of the nodes removed are designated as sentinel nodes.
