About C94.8

C94.8 is the ICD-10-CM diagnosis code for other specified leukemias. It belongs to category C94 (other leukemias of specified cell type), block C81-C96 (malignant neoplasms of lymphoid, hematopoietic and related tissue) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

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.
