Question:

CS Lymph Nodes--Kidney, renal pelvis: Under what circumstances would code 80 [Lymph nodes, NOS] be used to document the presence of positive lymph nodes? See Discussion.

Discussion:

The CS Schema for Kidney (Renal Parenchyma) states to use code 70 for Regional Lymph Nodes, NOS. The schema for for Renal Pelvis states to use code 50 for Regional Lymph Nodes, NOS. Both schemas have a Code 80, for Lymph Nodes, NOS that maps to N1 in both schemas.

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.Code 80 can be used for positive lymph nodes when you are unable to determine if they are regional or distant. CS Lymph Nodes code 80 is provided for this situation in accordance with the downstaging rule.

Code 80 should be used very infrequently and only when there is no indication whether the involved lymph nodes are regional or distant.
