Inquiry Details
References:
Heme & Lymph Manual & DB
Question:
Histology--Heme & Lymphoid Neoplasms: How is histology to be coded for acute lymphoblastic leukemia (ALL) and/or precursor B acute lymphoblastic leukemia (Pre-B ALL) for cases diagnosed 2010 and later? The Heme Database has two histology codes for this disease, both 9811/3 and 9836/3, which is the correct histology code?
Discussion:
Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].
See the Abstractor Notes section in the Heme DB, when determining how to code histology for a case. It indicates the code 9811/3 is effective for cases diagnosed 2010 and forward. The 9836/3 is listed as obsolete and refers you to code 9811/3. Make sure to check for a specific subtype of B lymphoblastic leukemia/lymphoma [9812/3 - 9818/3] before assigning the NOS code [9811/3].

History:
This SINQ question has been updated to the Hematopoietic & Lymphoid Neoplasm Manual & Database published January 2014.
The original answer below was written based on the rules in 2010.
For cases diagnosed 2010-2011, assign code 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].
See the 2010 Hematopoietic Database's Abstractor Notes when determining how to code histology for a case. The Abstractor Notes for 9811/3 indicate this code is effective for cases diagnosed 2010-2011. According to the Abstractor Notes for 9836/3 [precursor B-cell lymphoblastic leukemia], code Pre-BALL to 9811/3 for cases diagnosed 2010-2011.
The answers for SINQ questions with 2010 ID numbers were written using the 2010 Heme & Lymph Manual & DB. The instructions for using the 2010 Hematopoietic Database were written for the version of the software in use as of 5/24/2011. The user interface of the web-based 2010 Hematopoietic Database available from the SEER website varies slightly from the 5/24/2011 version in that the web-based version provides all the disease information in one scrollable window.
This SINQ question has been updated to the Hematopoietic & Lymphoid Neoplasm Manual & Database published January 2014.
The original answer below was written based on the rules in 2010
For cases diagnosed 2010-2011, access the 2010 Hematopoietic Database at http://seer.cancer.gov/tools/heme/. Click on Hematopoietic Project. Click on Hematopoietic and Lymphoid Database. For 2010-2011 diagnoses, click on the "use the 2010 database" label in the upper right corner of the screen. The 2010 Hematopoietic Coding Manual (PDF) button will appear to indicate the correct version of the program is available now for query.
