Question
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?

Discussion


Answer
For cases diagnosed 2010 and forward, access the Hematopoietic Database at Click on Hematopoietic and Lymphoid Database. In the search box, enter your histology or the ICD-O-3 code. Click on the link to that disease. In the "Help me code for dx year" field, enter the year of diagnosis. The Hematopoietic Coding Manual (PDF) button will appear.

Code the histology to B-cell lymphoma, NOS [9591/3]. The steps used to arrive at this decision are:

Step 1: Enter leukemia/lymphoma 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.

Step 2: Search again. Enter B-cell lymphoma NOS in the Heme DB to find the histology. Click on the SEARCH button. Click on the “Non-Hodgkin lymphoma, NOS” [9591/3] on the screen under the NAME area.

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.
