Grade, Differentiation--Lymphoma: What code is used to represent this field when the only grade/differentiation given is "low grade", "intermediate grade" or "high grade"?
Grade, Differentiation--Lymphoma/Leukemia: What code is used to represent this field for a lymph node biopsy that reveals "well differentiated lymphocytic lymphoma" and a bone marrow biopsy that reveals "chronic lymphocytic leukemia/well differentiated lymphocytic lymphoma"?
Grade, Differentiation--Lymphoma/Leukemia: Should the term "Pre-T" be added to code 5 [T-cell] in the ICD-O-3 Table 22, 6th Digit Code for Immunophenotype Designation for Lymphoma and Leukemia?
Grade, Differentiation--Hematopoietic: Is this field coded to 6 [B-cell] from a flow cytometry that specifies the percentage of B-cells that exist within the percentage of lymphoid cells in the bone marrow biopsy? See Description.
Grade, Differentiation--Breast: Should the Bloom-Richardson (BR) grade (low, intermediate, high) have a higher priority than terminology (i.e., well differentiated)? See discussion.
Grade, Differentiation--Breast: Is "histological grade" another way of saying "tubule formation" which would result in the following case having a Bloom-Richardson (BR) score of 7 which would be coded to grade 2? See discussion.
Grade, Differentiation--Breast: How do we code grade for a breast primary diagnosis of "Low grade invasive duct, modified Bloom-Richardson grade II/III (tubule formation 2, nuclear grade 1, mitotic rate 1)"? This appears to add up to a Bloom-Richardson score of 4, which does not fit with a Bloom-Richardson II/III.
Grade, Differentiation--Brain and CNS: Can grade IV be implied for brain primaries with the histology of glioblastoma multiforme, even if there is no statement of grade in the path report? See discussion.
