Inquiry Details
References:
#1: ICD-O-3
#2: Sngl vs Sbsq Prim Lymph & Hem. 02/28/2001
Question:
Multiple primaries/Histology--Lymphoma: How many primaries should be abstracted and how should the histology field(s) be coded in this situation?
How would the bone marrow involvement by only NHL be handled? Composite lymphoma (9596) as defined by SEER and ICD-O is NHL and HD in one node which fits the final impression on the removed cervical node. See Discussion.
Discussion:
Answer:
For cases diagnosed prior to 1/1/2010:This is a single primary. The histology code is 9596/3 [composite Hodgkin and non-Hodgkin lymphoma].
According to the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, 9596/3 followed by 9670/3 is one primary.
For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
