CS Extension

Note 1: Islets of Langerhans are distributed throughout the pancreas, and, therefore, any extension code can be used.
Note 2: Codes 400-800 are used for contiguous extension of tumor from the site of origin. Discontinuous involvement is coded in CS Mets at DX.
Note 3: If the only information regarding the tumor extension is the physician's statement of the "T" category, assign code 150, 200, 420, or 790. (Refer to CS Tumor Size table for instructions on coding tumor size if assigning code 150 or 200).

^ For Extension codes 100, 200 and 300 ONLY, the T category is assigned based on the value of CS Tumor Size, as shown in the Extension Size Table for this site.
* For Extension codes 100, 150, 200, and 300 ONLY, the T category is assigned based on the value of CS Tumor Size, as shown in the Extension Size Table for this site.
