C93.0Acute monoblastic/monocytic leukemia

C93.0 is the ICD-10-CM diagnosis code for acute monoblastic/monocytic leukemia. It belongs to category C93 (monocytic leukemia), 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 C93 (monocytic leukemia), C93.0 is specifically for acute monoblastic/monocytic leukemia. Related codes cover chronic myelomonocytic leukemia (C93.1), juvenile myelomonocytic leukemia (C93.3), unspecified (C93.9) and other monocytic leukemia (C93.Z).

To report this condition, pick the subcode that matches the documentation: C93.00 (not having achieved remission), C93.01 (in remission) and C93.02 (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.
