Answer:
For cases diagnosed prior to 1/1/2010:Code Small Lymphocytic Lymphoma. The current rules have not changed. Code to lymphoma because the diagnosis was made on a lymph node.
"Phenotypically consistent" means the lymph node contains CLL/SLL, not some other hematopoietic or metastatic disease.
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.
