Histology--Heme & Lymphoid Neoplasms: What is the correct histology code for a diagnosis of mature B cell leukemia/lymphoma diagnosed only through the peripheral blood?
This neoplasm must be coded to 9591/3 non-Hodgkin lymphoma, NOS/B-cell lymphoma, NOS. The diagnosis does not specify that this is a lymphoblastic leukemia/lymphoma, so the NOS code is more appropriate than the code for B-cell lymphoblastic leukemia/lymphoma, NOS 9811/3 in this case.
