CS Extension--Bladder: How should this field be coded for a high grade urothelial carcinoma with "focal micropapillary features and invasion of lamina propria, with a note stating there is invasive carcinoma focally involving thin muscle bundles...difficult to distinguish whether muscularis propria or muscularis mucosae"?
Primary Site/CS Extension--Lymphoma: How are these fields coded for a non-Hodgkins lymphoma case with scans that show non-specific parenchymal lung nodules and a large mediastinal mass? See Discussion.
Radiation Sequence with Surgery--Head & Neck: How is this field coded for a tonsil primary diagnosed on 4/16/07 by a regional lymph node FNA when the patient subsequently initiates radiation on 5/8/07 and has a tonsillectomy with neck dissection on 7/30/07?
CS Lymph Nodes--Head and Neck: How is this field coded when a positive neck FNA is followed by a neck dissection that contains one of seventeen positive lymph nodes? See Discussion.
CS Site Specific Factor--Head & Neck: How is Site Specific Factor 2 coded when the pathologist describes regional lymph nodes as "matted"? See Discussion.
Multiplicity Counter--Head & Neck: How is this field coded when a patient has carcinoma in the same location as a previous primary but it is unknown if there was a disease-free interval? See Discussion.
