Primary Site/CS Extension--Lymphoma: How are these fields coded for a non-Hodgkins lymphoma case with scans that show non-specific parenchymal lung nodules and a large mediastinal mass? See Discussion.
Primary Site/EOD-Extension/EOD-Lymph Nodes--All Sites: What codes are used to represent these fields for an "extramedullary myeloid tumor (granulocytic sarcoma)" of the colon with positive or negative lymph nodes?
Primary Site/Heme & Lymphoid Neoplasms--CLL/SLL: Should the primary site be coded C421 (bone marrow) for a diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) when the managing physician provides a Rai stage? See Discussion.
Primary Site/Histology (Pre-2007)--Unknown & ill-defined site: How are these fields coded for a markedly atypical high grade malignant neoplasm diagnosed by a fine needle aspiration of a large iliac mass, right buttock area? See Description.
Primary site/Histology--Head & Neck: How are these fields coded when the final diagnosis for a skull based mass is "neuroendocrine carcinoma" and the IHC studies are incompatible with a brain/spinal cord primary (ependymoma)? See Discussion.
Primary site/Histology--Heme & Lymphoid Neoplasms: How are these fields coded for a case with pathologic diagnosis of "anaplastic large cell lymphoma, ALK-negative" involving the brain and a clinical statement of involvement in the right inguinal lymph nodes and the right lower extremity by a cutaneous lymphoma? See Discussion.
Primary site/Histology--Heme & Lymphoid Neoplasms: Should the primary site and histology codes be updated when a patient with a history in 2005 of a bone marrow diagnosis of chronic lymphocytic leukemia later presents in 2010 with lymph node biopsy diagnosis of small B-cell lymphocytic leukemia?
Primary Site/Histology--Heme & Lymphoid Neoplasms: What are the correct primary site and histology for patient diagnosed with an oropharyngeal soft tissue mass revealing plasma cell neoplasm with 5-10% of marrow cellularity in 2022? See Discussion.
Primary Site/Histology--Intrahepatic Duct: How are primary site and histology coded for cholangiocarcinoma cases when the pathology only shows a liver tumor and other involvement. See Discussion.
Primary Site/Histology--Ovary: We are encountering a primary site, histologic type, and behavior combination edit based on the Cancer PathCHART (CPC) tables. Using the CPC*Search tool, C569 and 8441/3 is a valid combination. The diagnosis date is 01/13/2024. Should an over-ride be applied with this combination?
