MP/H Rules/Histology--Lung: What histology code and MP/H Rule applies to the Histologic Type described as adenocarcinoma, mixed invasive mucinous and non-mucinous which involves multiple lung tumors present in a single lobe? See Discussion.
MP/H Rules/Histology--Lung: Per SINQ 20110115, why is micropapillary adenocarcinoma of the lung coded to 8260 [papillary adenocarcinoma] rather than 8050 [papillary carcinoma]?
MP/H Rules/Histology--Lung: How should Diagnosis Date, Diagnostic Confirmation and Histology be coded for the LEFT lung mass in the following case?
PET shows a 3 cm mass in the left lung and a 2.9 cm mass in the right lung. No reportable terminology in PET. The right mass is biopsied and shows adenocarcinoma. The left mass is not biopsied. Based on rule M6, this should be reported as two primaries. No additional information in medical record. Patient expired.
MP/H Rules/Histology--Lung: How many primaries are accessioned if a pathology report for a right upper lobectomy with a chest wall resection describes the disease as 1) two foci of poorly differentiated non-small cell carcinoma, 2) mixed adenocarcinoma and non-mucinous bronchioalveolar carcinoma, each present as a separate focus? See Discussion.
MP/H Rules/Histology--Kidney: How should histology be coded for a clear cell renal cell carcinoma when the CAP protocol indicates sarcomatoid features are present? See Discussion.
MP/H Rules/Histology--Kidney: How is the histology coded and what rule(s) apply to the classification of succinate dehydrogenase-deficient renal cell carcinoma? See Discussion.
MP/H Rules/Histology--Kidney: How is the histology coded and what rule(s) apply for "cyst associated renal cell carcinoma," "cystic renal cell carcinoma," and "cystic renal cell carcinoma, clear cell type"? See Discussion.
