Collaborative Stage

Collaborative Stage for TNM 7 - Revised 12/22/2009 [ Schema ]

MerkelCellPenis

CS Extension

Note 1: In the case of multiple simultaneous tumors, code the tumor with greatest extension.
Note 2: Skin ulceration does not alter the Collaborative Stage classification.
Note 3: In-transit metastasis is coded in the CS Lymph Nodes field.
Note 4: If the ONLY information regarding the tumor extension is the physician's statement of the T category, assign code 320, 560, 630, or 810. (Refer to CS Tumor Size table for instructions on coding tumor size).

^ For codes 100, 300, 310, 320, 350, 400, 500, 560, 600, and 630 ONLY, the T category is assigned based on the value of CS Tumor Size as shown in the Extension Size Table for this site.
