"notes" : "**Note 1**: AJCC stages carcinoma of pharyngeal tonsil using schema for oropharynx.\n\n**Note 2**: The assignment of T1 and T2 categories for tumors of the oropharynx 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 330, 350, 575, 665, 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 3**: Use code 305 for localized tumor only if no information is available to assign code 100, 200, 305, or 310.",
"footnotes" : "- For CS Extension codes 105, 205, 305, 330, 350, 400, 500, 530, 555, and 565 ONLY, the T category for AJCC 7 staging is assigned based on the value of CS Tumor Size as shown in the Extension Size Table AJCC 7 for this schema.\n- For CS Extension codes 100 through 568, 575, and 580 ONLY, the T category for AJCC 6 staging is assigned based on the value of CS Tumor Size as shown in the Extension Size Table AJCC 6 for this schema.",
