MelanomaTongueBase

CS Extension

Note 1: The intrinsic muscles of tongue are four paired muscles within the tongue which control its shape. The extrinsic muscles originate from structures outside the tongue and control its positioning.
Note 2: AJCC does not include a Tis or TX for melanoma of mucosa of head and neck sites. CS Extension codes of 000 and 999 are mapped to NA and AJCC stage group is derived as NA.
Note 3: AJCC does not include a T1 or T2 category for mucosal melanoma of head and neck sites.
Note 4: Use codes 460-495 for extension involving the mucosa only of adjacent sites. Use higher codes for extension involving the deeper tissues of the primary or adjacent sites.
Note 5: Use code 305 for localized tumor only if no information is available to assign code 110, 405, 510, or 520.
Note 6: Use code 510, 785, 810, or 815 if the physician's assignment of T category is the only information available about the extent of the tumor.
