MP/H Rules/Histology--Corpus Uteri: Which MP/H rule applies in coding histology for a "high grade endometrioid adenocarcinoma with squamous differentiation (adenosquamous carcinoma)"? See Discussion.
MP/H Rules/Histology--Endometrium: How is histology coded when clear cell adenocarcinoma [8310/3] is stated to involve a "1.5 cm endometrial polyp"? See Discussion.
MP/H Rules/Histology--Esophagus: How is histology coded for a biopsy of the esophagus with a pathologic diagnosis of "adenocarcinoma, intestinal type" when there is no evidence of a gastric tumor in scans or EDG? See Discussion.
MP/H Rules/Histology--Esophagus: Will the AJCC TNM 7 having separate stage groupings for squamous cell carcinoma and adenocarcinoma result in coding histology for a tumor of mixed squamous cell carcinoma and adenocarcinoma to squamous cell carcinoma because it has the poorer prognosis? See Discussion.
MP/H Rules/Histology--Gallbladder: What histology is coded for a tumor described as "90% high grade neuroendocrine ca, large cell type; and 10% low grade adenocarcinoma, conventional type"?
MP/H Rules/Histology--Head & Neck: If the final diagnosis states "see microscopic description," can the micro information be used to code the histology? See Discussion.
MP/H Rules/Histology--Kidney, renal pelvis: How is histology coded for a tumor described as "renal cell carcinoma, clear cell with rhabdoid features"? See Discussion.
MP/H Rules/Histology--Kidney: How do you code histology for a renal cell carcinoma when pathologists disagree as to whether or not the tumor is consistent with thyroid-like follicular carcinoma of the kidney? See Discussion.
