ICD-10 Code C93.00 – Acute monoblastic/monocytic leukemia, not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C93.00 – Acute monoblastic/monocytic leukemia, not having achieved remission
What it is
C93.00 identifies acute monoblastic/monocytic leukemia that has not reached remission. Use it when the record clearly states this leukemia type and confirms active disease.
Clinical signs
Patients often present with findings of acute leukemia such as fatigue, infection, bleeding, or anemia. Diagnosis is based on documented leukemia subtype; clinical features vary and you should refer to documentation.
When to use this code
Use this code when the provider documents acute monoblastic or monocytic leukemia and states it is not in remission. It also fits when the chart shows persistent or relapsed active disease without remission. Code the documented status, not assumptions from treatment history.
Do not use for
Do not use this code if the leukemia is in remission or if the subtype is not specifically acute monoblastic/monocytic leukemia. Check documentation when the record only says acute myeloid leukemia or leukemia NOS.
Coding tip
Confirm both the subtype and the remission status in the provider note before assigning C93.00.
