Question:

Surgery of Primary Site--Breast: How is this field coded when a mastectomy and a sentinel lymph node excision, that yields only one lymph node, are performed? See Discussion.

Discussion:

Is there a minimum number of lymph nodes that must be removed in order to code a modified radical mastectomy?

Answer:

Assign code 41 [Total (simple) mastectomy...] for a simple mastectomy with removal of one or more sentinel lymph nodes. As long as the nodes removed are designated sentinel, use code 41 for a simple mastectomy.
