Question 20190040
Inquiry Details
References:
#1: Heme & Lymph Manual & DB
#2: WHO Class Hem & Lymph Tumors
Question:
Reportability--Heme & Lymphoid Neoplasms: Is peripheral blood with a diagnosis of monoclonal B-cell lymphocytosis (MBL) with chronic lymphocytic leukemia (CLL) phenotype reportable for any year? See Discussion.
Discussion:
SINQ 20180050 and 20130041 appear to have conflicting answers regarding the reportability of MBL with CLL (immuno)phenotype.
While the question content of SINQ 20180050 does not reference the CLL phenotype, it is included in the Discussion as part of the oncologist's assessment. The answer does not address the clinical diagnosis of MBL with CLL-phenotype and simply states that monoclonal B-cell lymphocytosis is not reportable.
SINQ 20130041 does include the CLL phenotype information in the primary question and it is expanded on in the discussion as present in peripheral blood. Based on that information, the answer is that it should be reportable and coded as CLL (9823/3).
Answer:
The description in the question is for 9823/1 per WHO blue book 2016. This description and code are not reportable. We will review the other SINQ questions and revise if necessary.
