Question:

Histology: Must every word in the ICD-O-3 code definition appear in the diagnosis in order to assign that ICD-O-3 code? See Discussion.

Discussion:

Is the diagnosis "Acute myeloid leukemia, M2" coded to Acute myeloid leukemia with maturation, FAB M2, NOS, (9874/3) or to Acute myeloid leukemia, NOS, (9861/3)?

Answer:

For cases diagnosed prior to 1/1/2010:The general instructions for assigning histology codes are to code as precisely as possible. Acute myeloid leukemia with maturation is the definition of the FAB M2 category. A pathologist does not need to provide every word in the term associated with an ICD-O code; pathologists don't always talk that way. AML M2 is a very specific diagnosis and should be coded to 9874/3.

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.
