EOD-Extension--Kidney: If a "tumor thrombus" in a renal vein is discontinuous from the primary tumor in the kidney, is it still coded to 60 [Tumor thrombus in a renal vein, NOS], rather than 85 [Metastasis]?
EOD-Extension/EOD-Lymph Nodes--Lung: Is "subcarinal extension" with no mention of lymph nodes coded in the EOD extension field or in the EOD lymph node involvement field? See discussion.
EOD-Extension--Head & Neck: How much information is needed for a head and neck primary in order to code extension to localized versus unknown? What code is used to represent this field when the only information for a buccal cavity primary is a positive aspiration of the buccal mass?
EOD-Lymph Nodes--Breast: How do you code this field when the gross description on the pathology report states "nodal tissue is matted" but only 1/18 lymph nodes is found to contain micrometastatsis per the microscopic description of the report?
EOD-Lymph Nodes/TNM--Breast: Do we code these lymph nodes fields for a breast primary that describes ipsilateral axillary lymph node involvement as "extending through the lymph node capsule and into perinodal soft tissue/fat" as "fixed/matted"?
EOD-Lymph Nodes--Head & Neck: When a physician provides only "Stage IV" (i.e., an abbreviated stage) for a right posterior tongue primary with lateral extension into the oropharynx and hypopharynx, can you assume "palpable" level 2, 3 and 5 lymph nodes are involved?
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: How are these fields coded if radiation to the primary site and/or regional lymph nodes is performed prior to surgery?
EOD-Size of Primary Tumor--Colon: When an adenocarcinoma is stated to be arising in an adenoma and the "tumor size" stated in the final pathologic diagnosis is the same size as the mass described in the gross description, should we assume that the entire polyp has been totally/near totally replaced by tumor and code the tumor size stated in the final path diagnosis?
EOD-Size of Primary Tumor--Prostate: When there are multiple nodules in the prostate, can size of tumor be based on the size of the largest nodule? See discussion.
