MP/H Rules/Histology--Bladder: What rule and histology code apply when a TURB final diagnosis is small cell neuroendocrine carcinoma and high grade urothelial carcinoma? See Discussion.
Reportability--Ovary: Is an adult granulosa cell tumor of the right adnexa reportable if the left adnexa, diaphragm and paratubal tissue are reported to be consistent with metastasis? See discussion.
MP/H Rules/Histology--Breast: Given that the current MP/H rules do not recognize specific types of lobular carcinoma, should the histology for an invasive pleomorphic lobular carcinoma be coded to 8022/3 [pleomorphic carcinoma] or 8520/3 [lobular carcinoma]? See Discussion.
Histology/Primary site--Heme & Lymphoid Neoplasms: How is the primary site and histology coded when a bladder biopsy reveals myeloid sarcoma and a simultaneously performed bone marrow biopsy demonstrates acute myeloid leukemia? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned and what is the histology for each if a bone marrow diagnosis reveals co-existent systemic mastocytosis and a lymphoplasmacytic neoplasm? See Discussion.
MP/H Rules/Histology--Breast: What is the histology code for "invasive carcinoma of the breast, no special type" as the final diagnosis on a pathology report? See Discussion.
Date of diagnosis--Heme and Lymphoid Neoplasms: Is the date of diagnosis coded to the date a bone marrow biopsy revealed "plasma cell neoplasm; plasma cells are < 10%" or the date a diagnosis of myeloma was noted in the Discharge Summary? See Discussion.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a 2013 diagnosis of right leg skin nodules, consistent with plasmacytoma/plasma cell myeloma, follows a 3/20/07 biopsy diagnosis of multiple myeloma?
