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?
For cases diagnosed 2012 and later, access the Hematopoietic Database at http://seer.cancer.gov/tools/heme/.
Click on Hematopoietic Project. Click on Hematopoietic and Lymphoid Database. The 2012 Hematopoietic Coding Manual (PDF) button will appear to indicate the correct version of the program is available now for query.
Code the histology to B-cell lymphoma, NOS [9591/3]. The steps used to arrive at this decision are:
Step 1: Enter in the Heme DB to find the histology. Click on the SEARCH button. Multiple results are returned, however there is no B-cell leukemia/lymphoma NOS code. The patient is not stated to have B-cell lymphoblastic leukemia/lymphoma so none of these histology codes can be used. leukemia/lymphoma
Step 2: Search again. Enter in the Heme DB to find the histology. Click on the SEARCH button. Ensure that “Non-Hodgkin lymphoma, NOS” [9591/3] is highlighted on the screen. B-cell lymphoma NOS
Step 3: Scroll down to the ALTERNATIVE NAMES section. B-cell lymphoma, NOS, is a synonym for Non-Hodgkin lymphoma, NOS. Code the histology as 9591/3 [B-cell lymphoma NOS].
NOTE: The diagnosis does not specify that this is a lymphoblastic leukemia/lymphoma, so the histology code 9811/3 [B-cell lymphoblastic leukemia/lymphoma, NOS] cannot be applied. The B-cell lymphoma NOS code [9591/3] is the most appropriate code in this case.
