Clinical Assessment of Regional Lymph Nodes

Notes

**Note 1**: Clinically evident regional lymph nodes are based on information from the diagnostic workup. This might include: physical examination, imaging, diagnostic lymph node biopsy and exploratory surgery (without a resection). **Note 2**: In the rare instance that the number of clinically positive nodes is stated but a clinical N category is not stated, use the code that reflects the most specific statement about the number of nodes. **Note 3**: If there is no diagnostic work-up to assess regional lymph nodes, use code 999. Do not apply the inaccessible nodes rule that presumes unmentioned nodes to be negative.

Code Description
000 Nodes not clinically evident; imaging of regional nodes performed and nodes not mentioned
010 Metastasis in 1 regional node, determined clinically

Stated as clinical N1a
020 Metastases in 2-3 regional nodes, determined clinically

Stated as clinical N1b
030 OBSOLETE DATA REVIEWED AND CHANGED V0204
Clinical assessment of lymph nodes only are coded in this site-specific factor, tumor deposits are only assessed histologically. Cases coded to 030 should be reviewed and recoded to the clinical lymph node involvement. Tumor deposit information is coded in CS Lymph Nodes and CS Site-Specific Factor 4.

Tumor deposits without regional nodal metastasis

Stated as clinical N1c
100 Metastases in 1-3 regional nodes, determined clinically

Stated as clinical N1 [NOS]
110 Metastases in 4-6 regional nodes, determined clinically

Stated as clinical N2a
120 Metastases in 7 or more regional nodes, determined clinically

Stated as clinical N2b
200 Metastases in 4 or more regional nodes, determined clinically Stated as clinical N2 [NOS]
400 Clinically positive regional node(s), NOS
888 OBSOLETE DATA CONVERTED V0200
