Other Cancer-Directed Therapy--Hematopoietic, NOS: Is there a hierarchy for selecting which code to use when a patient receives more than one type of "other treatment"? See Description.
Date of Diagnosis: When the clinical information on a scan indicates a history of cancer, how do you code the month and/or year of diagnosis given these terms: "early in year," "late in year," "2-3 months ago," "7 months ago," "new diagnosis." See Description.
Primary site--Head & Neck: When there is invasive in one subsite and in situ in another, do you code the subsite with the invasive only? Would the correct site be C320, C328, or C329? See discussion.
Grade, Differentiation--Bladder: If the only indication of grade for a bladder primary is "grade 2, NOS," and we do not know the grading system being used by the pathologist, is the numeric grade 2 coded?
Grade--Appendix: What is the code and term to use for the grade/differentiation field for well differentiated, Grade 2 neuroendocrine tumor (NET)? See Discussion.
Reportability--Brain and CNS: Does a neurofibroma actually arise in peripheral nerve roots like a schwannoma even if it is referred to as a "C6-T1 intradural spinal cord tumor" and is therefore not reportable?
Reportability--Skin: Is this reportable? If so, what is the correct histology code? The pathology report says, " bx of 0.7 x 0.5 cm gray-pink papule on tan-pink skin of left inferior centra malar cheek revealed invasive SCC of skin, signet ring cell type, invading papillary dermis; LVI neg; "findings are diag of SCC exhibiting the rare signet ring histologic subtype"; deep margin positive for tumor but peripheral margins clear;".
