"notes" : "**Note 1**: Periosteum is a fibrous membrane that wraps the outer surface of bones. Cortical bone is the dense compact outer layer of the bone. Trabecular, cancellous, or spongy bone (spongiosa) is a porous network of tissue filling the interior of bone, decreasing weight and allowing room for blood vessels and marrow.\n\n**Note 2**: AJCC assigns the T category based on size when bone involvement is limited to the cortex . Involvement through cortical bone is required for assignment of T4a.\n\n**Note 3**: The assignment of T1, T2 , and T3 categories for tumors of the lip and oral cavity is based on tumor size. A physician's statement of the T category may be used to code 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, other than the physician's statement of the T category. Use codes 405, 410, 415, 775, 810, or 815 as appropriate to code CS Extension based on a statement of T when no other extension information is available.\n\n**Note 4**: Use code 300 for localized tumor only if no information is available to assign codes 100, 200, 400, 405, 410, or 415.",
