ICD-10 Code C93.Z1 – Other Monocytic Leukemia, in Remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C93.Z1 – Other monocytic leukemia, in remission
What it is
C93.Z1 identifies a history of other monocytic leukemia that is currently in remission. Use it when the leukemia is not active, but the diagnosis remains clinically relevant for ongoing care.
Clinical signs
Clinical features vary; refer to documentation. In remission, there is no active evidence of disease, but the patient may still be followed for prior monocytic leukemia and recurrence monitoring.
When to use this code
Use this code when the record clearly states other monocytic leukemia is in remission. It may appear in follow-up visits, survivorship care, or problem lists when the condition is not currently active. Confirm that the provider documents remission rather than only a past history.
Do not use for
Do not use this code for active monocytic leukemia or when remission is not documented. If the chart only says “history of leukemia” without specifying remission, check documentation.
Coding tip
Code remission only when the provider explicitly states it; otherwise, query or rely on documented active disease status.
