Histology--Heme & Lymphoid Neoplasms: Is histology coded to AML, NOS [9861/3] for a bone marrow biopsy with a diagnosis of acute myeloid leukemia evolving from myelodysplastic syndrome (MDS) if the cytogenetics revealed trisomy 13? See Discussion.
Histology--Heme & Lymphoid Neoplasms: Should all cases of precursor B acute lymphoblastic leukemia diagnosed 1/1/10 and later with histology coded to 9836/3 have the values changed to 9811/3 per the Heme DB Abstractor Notes section or should they remain coded 9836/3.
Histology--Heme & Lymphoid Neoplasms: Should the higher histology code associated with grade 1 follicular lymphoma [9695/3] be used rather than grade 2 follicular lymphoma [9691/3] in cases of follicular lymphoma grade 1-2?
Histology--Heme & Lymphoid Neoplasms: Should the histology be coded to a therapy-related myeloid neoplasm when the physician states the diagnosis of acute myeloid leukemia is secondary to treatment with Imuran? See Discussion.
Histology--Heme & Lymphoid Neoplasms: What is the correct histology code for a diagnosis of mature B cell leukemia/lymphoma diagnosed only on a peripheral blood smear?
Histology--Heme & Lymphoid Neoplasms: Why did the hematopoietic histology rule change regarding the coding of small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) from the lymphoma code (9670/3) to leukemia (9823/3) when both tissue and bone marrow are involved? See Discussion.
Histology--Leukemia: How is "T-Cell prolymphocytic leukemia, cerebriform (Sezary cell-like) variant" coded when the pathology report COMMENT states: The cerebriform (Sezary cell-like) variant accounts for about 5% of cases of T-cell prolymphocytic leukemia?
Histology--Leukemia: How is a "plasmacytoid dendritic cell leukemia/lymphoma" coded when it is discovered on a bone marrow biopsy for a patient who presented with multiple enlarged lymph nodes and the discharge diagnosis was Type 2 plasmacytoid dendritic cell leukemia?
