Question:

CS Lymph Nodes/CS Site Specific Factor 3--Breast: How are positive intramammary lymph nodes reflected in these fields? See Discussion.

Discussion:

Patient with breast cancer underwent mastectomy. No axillary lymph nodes were positive, but 1 out of 2 intramammary lymph nodes were positive for mets (greater than 2 mm). CS Lymph node codes describe axillary and internal mammary nodes, but do not describe intramammary lymph nodes.

Answer:

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Intramammary lymph nodes are coded as axillary lymph nodes for staging purposes. Intramammary node are nodes within the breast tissue. Both staging and treatment suggest these are equivalent to axillary nodes.
