Gallbladder

CS Mets at DX

Note: Para-aortic and pericaval lymph nodes are classified as regional nodes for AJCC 7 staging and are coded in CS Lymph Nodes.

* For CS Mets at DX codes 00 and 99, the M category for AJCC 6 staging is assigned based on the coding of CS Lymph Nodes and CS Mets at DX as shown in the Lymph Nodes Mets at DX AJCC 6 Table for this schema.
