CS Site Specific Factor 6--Breast: If the tumor size for the breast is unknown, and it is unknown whether the tumor is mixed in situ and invasive or "pure", how is SSF6 to be coded? See Discussion.
CS Lymph Nodes/Reg LN Pos/Exam: Is a final pathologic diagnosis of "Level 8 lymph node: Fibroadipose tissue containing a minute lymphoid aggregate, negative for malignancy" a lymph node for the purpose of coding these fields?
CS Lymph Nodes--Ovary: Are positive lymph nodes removed from "colon tissue" during a modified posterior pelvic debulking regional or distant? If regional, what is the appropriate CS LN code?
CS Extension/Ambiguous terminology--Pancreas: Should an exception be made for "abuts" or "encased/encasing" regarding CS pancreas extension? See Discussion.
CS Extension--Brain and CNS: How is CS Extension coded for a malignant meningioma that demonstrates extension into adjacent brain tissue?
For malignant brain tumors, code 60 represents extension into the meninges. Would code 60 be the correct code for extension from a malignant meningioma into brain tissue?
