Question:

Histology--Hematopoietic, NOS: If an initial bone marrow diagnosis is "...more compatible with CMML/MPD" and within three months the final diagnosis per the oncologist is "MPD/CMML with acute myeloid leukemia transformation," is histology coded to CMML or AML? See Discussion.

Discussion:

09/06 BM Bx elsewhere was "compatible with MDS but more compatible with CMML/MPD" per MD notes.

10/06 BM Bx "...poor prognosis MDS, best classified as RAEB-2"

11/06 BM Bx "myeloproliferative CMML with leukemic transformation"

(on evaluation for BMT)

12/12/06 Pt was admitted with rapidly progressive disease & was started on chemo to try to get into remission for BMT. Final dx by oncologist is "MPD/CMML with acute myeloid leukemia transformation".

Answer:

For cases diagnosed prior to 1/1/2010:Code CMML for this case. Code the histology at initial diagnosis. This patient had rapid progression, but the initial diagnosis was "more compatible with CMML/MPD."

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.
