2013 ICD-9-CM Diagnosis Code 205.1
Myeloid leukemia chronic
- chronic leukemia in which myeloid progenitor cells predominate; the hallmark of CML, the Philadelphia chromosome, is a reciprocal translocation between chromosomes 9 and 22 which activates the proto- oncogene c-abl.
- A slowly progressing disease in which too many white blood cells are made in the bone marrow.
- The most common chronic myeloproliferative disorder characterized by neutrophilic leukocytosis. It is associated with the Philadelphia (Ph) chromosome and/or the BCR/ABL fusion gene. Most patients are middle-aged or elderly. Common findings at presentation include fatigue, weight loss, anemia, night sweats, and splenomegaly. The disease is bi- or triphasic; an initial indolent chronic phase is followed by an accelerated or blast phase. Allogeneic bone marrow transplantation is currently the only curative therapy (adapted from WHO 2001).
- There are 3 ICD-9-CM codes below 205.1 that define this diagnosis in greater detail. Do not use this code on a reimbursement claim.
