EOD-Size of Primary Tumor: Can you code the known size of the residual tumor in a further resected specimen if the size of the tumor in a prior excisional biopsy is unknown? See discussion.
Surgical Procedure of Other Site: Is the excision of a distant lymph node or a fine needle aspirate (FNA) of a distant lymph node coded as a Surgical Procedure of Other Site, even though they are performed for diagnostic purposes and not intended as treatment?
Scope of Regional Lymph Node Surgery/EOD-Number of Regional Nodes Examined: What codes is used to represent these fields when the surgeon states that a "lymph node dissection" was done, but no nodes are identified in the pathology report?
Reportability/Ambiguous Terminology--Breast: Should the American College of Radiology (ACR) BI-RADS assessment categories 4 [Suspicious Abnormality--biopsy should be considered] and 5 [Highly Suggestive of malignancy-appropriate action should be taken], impressions for mammograms and sonograms, be used as the sole basis for reportability? See discussion.
EOD-Extension--Lung: Are "aortico-pulmonary window", "paratracheal space", and "subcarina" coded in the EOD extension field or in the EOD lymph node involvement field? See discussion.
Multiple Primaries (Pre-2007)--Bladder: Should an invasive malignancy following an in situ malignancy by more than two months be a new primary? Why? See discussion.
EOD-Extension--Pancreas: How do you code extension when CT scan shows a mass in the head of the pancreas "encompassing" the hepatic branch of the celiac artery? See discussion.
