Histology--Heme & Lymphoid Neoplasms: How is the histology coded for a "cutaneous diffuse large B-cell lymphoma, leg type" that has been verified as a valid diagnosis with prognostic factors including age and number of lesions on the legs?
Histology--Heme & Lymphoid Neoplasms: How is the histology coded if a biopsy final diagnosis is diffuse large B-cell lymphoma but the physician's final diagnosis favored anaplastic large cell lymphoma? See Discussion.
Histology--Heme & Lymphoid Neoplasms: How is the histology coded if a pelvic mass biopsy is positive for B-cell non-Hodgkin lymphoma and a mediastinal lymph node biopsy is positive for follicular lymphoma, grade 1? See Discussion.
Histology--Heme & Lymphoid Neoplasms: How is the histology coded if the bone marrow biopsy favors lymphoplasmacytoid lymphoma and the physician states the diagnosis is lymphoplasmacytic lymphoma-Waldenstrom's macroglobulinemia? See Discussion.
Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the bone marrow biopsy shows acute myeloid leukemia, but the physician states this is therapy-related AML secondary to prior radiation treatment? See Discussion.
Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the original slides are reviewed at a later date and the revised diagnosis changes the histology? See Discussion.
Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the pathology report states the morphologic features and immunophenotype of a low grade B-cell lymphoma are most compatible with lymphoplasmacytic lymphoma or marginal zone lymphoma?
Histology--Heme & Lymphoid Neoplasms: How is the pre-2010 histology coded for a "follicular grade 2, non-Hodgkin lymphoma with marginal zone B-cell differentiation"? See Discussion.
