CS Lymph Nodes

Note 1: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in CS Mets at DX.
Note 2: Celiac nodes are classified as distant nodes for AJCC 7 staging. These nodes are coded in CS Mets at DX.

Code	Description	TNM 7 Map	TNM 6 Map	SS77 Map	SS2000 Map
000	No regional lymph node involvement	N0	*	NONE	NONE
150	Regional lymph nodes: Cystic duct (node of the neck of the gallbladder) (Calot's node) Hepatic artery Hilar (in the hepatoduodenal ligament) Node of the foramen of Winslow (omental) (epiploic) Pancreaticoduodenal: Anterior Posterior Pericholedochal (node along common bile duct) Periduodenal Peripancreatic (near head of pancreas only) Periportal Porta hepatis (portal) (hilar) (in hilus of liver) Regional lymph nodes, NOS	N1	N1	RN	RN
350	OBSOLETE DATA RETAINED AND REVIEWED V0203 See codes 000, 150, and 355, and CS Mets at DX codes 07, 20, and 45 Regional lymph nodes: Celiac Superior mesenteric	N1	N1	D	D
355	Regional lymph nodes Superior mesenteric artery Superior mesenteric vein	N1	N1	D	D
500	Stated as N1 with no other information on regional lymph nodes	N1	N1	RN	RN
800	Lymph nodes, NOS	N1	N1	RN	RN
999	Unknown; regional lymph nodes not stated Regional lymph node(s) cannot be assessed Not documented in patient record	NX	*	U	U

* For CS Lymph Nodes code 000 and 999, the N category for AJCC 6 staging category is determined by the value in CS Mets at DX as shown in the Lymph Nodes Mets at DX AJCC 6 Table for this schema.
