CS Tumor Size/CS Site Specific Factor--Breast: When tumor size is unknown, but it is known that both in situ and invasive components are present, how should CS Tumor Size and SSF6 be coded? See Discussion.
CS Lymph Nodes/CS Mets at Dx--Lung: In which CS field is a focus of squamous cell carcinoma in the soft tissue coded for a lung primary? See Discussion.
CS Lymph Nodes--Kidney, renal pelvis: Under what circumstances would code 80 [Lymph nodes, NOS] be used to document the presence of positive lymph nodes? See Discussion.
Primary Site/CS Tumor Size/CS Extension--Lung: How are these fields coded when a chest CT for lung cancer documents multiple masses in different lobes of the lung? See Discussion.
CS Eval--Colon: When the surgical resection occurs after radiation or chemo, how is the tumor size/extension evaluation field coded when there is no mention of the tumor size or extension in the surgical resection pathology report? See Discussion.
