Ambiguous terminology/Histology--Heme & Lymphoid Neoplasms: How is histology coded when a skin of lip pathology report demonstrates neoplastic lymphoid infiltrate with small B cells, compatible with B-cell small lymphocytic lymphoma/chronic lymphocytic leukemia? See Discussion.
Ambiguous terminology is not used to code histology. What is the correct histology for this case? There was no other clinical statement from the physician regarding the histology following the release of the pathology report diagnosis.
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma]. This primary was accessioned based on reportable ambiguous terminology. The surgical pathology report was compatible with B-cell small lymphocytic lymphoma/chronic lymphocytic leukemia, “compatible with” is a reportable ambiguous term. A neoplastic lymphoid infiltrate is not a reportable diagnosis. Therefore, a diagnosis compatible with CLL/SLL is coded as histology code 9823/3.
The statement that you do not use ambiguous terms to code histology is intended for those NOS histologies with an ambiguous term being used to describe the subtype.

Assign 9823/3, SLL/CLL, because the surgical pathology report states the presence of the small B cells along with the ambiguous terminology of CLL.
We consulted our expert pathologist on this question. Per the Hematopoietic database, SLL/CLL is defined by the presence of small round B lymphocytes.
