Question:
CS Lymph Nodes--Breast: Which category has priority when both apply, "Regional lymph nodes, NOS" or "Stated as N_, NOS"? See Discussion.
Discussion:
Example: When there is a clinical diagnosis of axillary lymph node metastasis for a breast primary on a physical exam "Enlarged axillary lymph nodes suspicious for metastatic involvement", as well as a clinical N1 designation, do we code as 60 [Axillary LNS, NOS] or 26 [Stated as N1, NOS]?
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.For the example provided, assign code 25 [Movable axillary lymph node(s)...] for "Enlarged axillary lymph nodes suspicious for metastatic involvement." Code 60 [Axillary/regional lymph node(s), NOS] is the least specific and would not be used in this case because axillary nodes are defined in code 25. Code 26 is for cases in which "N1, NOS" documented by the physician is the only information available.
