CS Extension

Note 1: If the only information regarding the tumor extension is the clinician's physician's statement of the "T" category, assign code 310, 320, 330 or 850. (Refer to CS Tumor Size table for instructions on coding tumor size if assigning code 310, 320 or 330).
Note 2: Codes 600-800 are used for contiguous extension from the site of origin. Discontinuous involvement is coded in CS Mets at DX.

^ For codes 100-400 ONLY, the T category is assigned based on the value of CS Tumor Size, as shown in the Extension Size Table for this site.
