Question:

Histology/Date of Diagnosis--Hematopoietic, NOS: What code is used to represent histology for a June 2001 diagnosis of "myelodysplastic syndrome" followed by a September 2001 bone marrow biopsy diagnosis of "myelodysplasia evolving into an acute leukemic state"?

Discussion:

Answer:

For cases diagnosed prior to 1/1/2010:

Code the Histology field to 9989/3 [myelodysplastic syndrome] and the Date of Diagnosis field to June 2001.

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.
