Histology--Heme & Lymphoid Neoplasms: How is histology coded for a pathology report final diagnosis of diffuse large B-cell lymphoma (50%) and follicular lymphoma, 3A (50%)?
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a lymphoma with multifocal bone and epidural involvement but no lymph node involvement if the physician does not clearly state the primary site? See Discussion.
Primary site/Heme & Lymphoid Neoplasms: How is the primary site coded if the patient presents with diffuse B cell lymphoma involving the nasopharynx and right maxillary sinus with bilateral cervical, right supraclavicular and axillary lymph nodes? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How is this field coded when a 5/26/10 colonoscopy reveals ulcers in the cecum, ascending, transverse, descending, and sigmoid colon and, the final diagnosis on the pathology report is post-transplant lymphoproliferative disorder [9971/3]?
Histology--Heme & Lymphoid Neoplasms: How is this field coded for a patient with a negative bone marrow and multiple plasmacytomas in different bone sites (e.g., thoracic vertebrae and left femur)?
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of Langerhans cell histiocytosis with extensive bony metastatic disease and lymphadenopathy? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded when both a lymph node biopsy and peripheral blood are positive for CLL/SLL? See Discussion.
Primary site/Histology--Heme & Lymphoid Neoplasms: How are the site and histology fields coded if a bone marrow biopsy shows, "B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma," but the patient has no palpable lymphadenopathy and no scans were done? See Discussion.
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded, and which PH rule applies, when chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is diagnosed simultaneously by biopsies of both lymph node(s) and the bone marrow?
Primary site--CLL/SLL: How is the primary site coded and what rule applies when no bone marrow biopsy is performed on a patient diagnosed with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) which was based on the results of an axillary biopsy, positive peripheral blood and a CT scan showing multiple lymph nodes involved above and below the diaphragm? See Discussion
