Question:
CS Lymph Nodes--Breast: Is it better to code to 26 [Stated as N1, NOS] or 28 [Stated as N2, NOS] instead of 60 [Axillary/regional lymph nodes, NOS; Lymph nodes, NOS] when the only information in the medical record is the TNM N1 or N2 physician stage?
Discussion:
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.
Yes. When the only indication of lymph node involvement is the physician's N category from TNM, code the numerically lowest equivalent CS Lymph Nodes code for that N category.
In the breast schema, CS Lymph Nodes code 26 corresponds to N1, NOS and code 28 corresponds to N2, NOS.
