Inquiry Details

ICD-O-3
Question:
Primary Site/Grade, Differentiation, Cell indicator--Lymphoma: Will a Grade, Differentiation code of 6 [B-cell] for a lymphoma coded to primary site C80.9 [unknown] fail edits? See Discussion.
Discussion:
Patient had a large mass in chest wall that was excised and found to be large B cell lymphoma. Scans mentioned no involvement of lymph nodes but indicated nodules in the liver thought to be lymphoma as well.
Answer:
For cases diagnosed prior to 1/1/2010:The combination of a primary site C809 with a Grade, Differentiation code of 6 when used for a lymphoma will not fail SEER edits. Avoid coding primary site to C809 when possible. Code primary site for the example above to C761 [Chest wall, NOS]. The chest wall is the only area of involvement, except for "liver nodules." Liver is an unlikely primary site for lymphoma.
For cases diagnosed 2010 forward, 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.
