]> M-8247 C63.2 Scrotum, NOS Note: This schema is used for Merkel cell carcinoma only. &commontumorsizeskinmerkel; CS Extension Note 1: In the case of multiple simultaneous tumors, code the tumor with the greatest extension. Note 2: Skin ulceration does not alter the AJCC T category. Note 3: In-transit metastasis is coded in CS Lymph Nodes. Note 4: The assignment of the T1, T2, and T3 categories for Merkel cell carcinomas is based on tumor size. A physician's statement of the T category may be used to code both CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently; for example, the record may document size but not extension. Use codes 310, 320, 330, and 810 as appropriate to code CS Extension based on a statement of T when no other extension information is available.

Distant nodes are coded in CS Mets at DX. Note 2: Bilateral nodes are considered regional nodes for tumors with bidirectional drainage to primary nodal basins, as shown on lymphoscintigraphy. Clinical assessment of bilateral regional nodal involvement is required for tumors where lymphoscintigraphy is not performed. Note 3: Contiguous or secondary nodal basins are the next nodal drainage basins beyond the primary nodal basins. Secondary basins are considered regional for AJCC staging but may be distant for Summary Stage. Use code 100 for involvement of nodes in secondary nodal basins not otherwise specified. Note 4: In-transit metastasis is defined as a tumor distinct from the primary lesion and located either between the primary lesion and the draining regional lymph nodes or distal to the primary lesion. In-transit metastasis is coded in CS Lymph Nodes. Note 5: Isolated tumor cells (ITCs) should be considered positive nodes. If only ITCs are present, use code 010. Note 6: If the only information about lymph nodes is a statement of N1 involvement without a clinical or pathologic designation, use code 360.
