ICD-10 code for chronic eosinophilic leukemia

The ICD-10-CM code for chronic eosinophilic leukemia is C94.8 (Other specified leukemias).

Within C94, choose C94.8 (Other specified leukemias) only when documentation doesn't support a more specific option: acute erythroid leukemia (C94.0), acute megakaryoblastic leukemia (C94.2), mast cell leukemia (C94.3), acute panmyelosis with myelofibrosis (C94.4) and myelodysplastic disease, not elsewhere classified (C94.6).

To report this condition, pick the subcode that matches the documentation: C94.80 (not having achieved remission), C94.81 (in remission) and C94.82 (in relapse).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
