Question: 20130095 Status

Source 1:   Heme & Lymph Manual & DB
Source 2:  

Grade--Heme & Lymphoid Neoplasms: How is grade coded for acute lymphoblastic leukemia, NOS? See Discussion.

The Heme DB indicates histology code 9811/3 [B lymphoblastic leukemia/lymphoma] is the current histology code to use for the now obsolete term of acute lymphoblastic leukemia [9835/3]. The Heme DB entry for histology code 9835/3 states to “Code grade specified by pathologist. If no grade specified, code 9.” The Heme DB entry for the current histology code, 9811/3, states to code the grade to 6 [B-cell]. Should grade be coded to 6 [B-cell] for all cases coded to histology code 9811/3?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at

Code the grade to 6 [B-cell] for all cases of 9811/3 [B lymphoblastic leukemia/lymphoma] per Rule G3 in the Heme Manual.

Acute lymphoblastic leukemia, NOS [9835/3] is an obsolete code and cannot be used for cases diagnosed 2010 and later. The Heme DB indicates the correct histology code is 9811/3 and grade 6 [B-cell] for cases diagnosed 2010 and later.

For cases of acute lymphoblastic lymphoma, NOS [9835/3] diagnosed prior to 2010, use the pathology report information to code the grade. Code the grade as 9 [unknown] if the pathology report does not specify the grade.
