ICD-10 Code C93.Z0 – Other monocytic leukemia, not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C93.Z0 – Other monocytic leukemia, not having achieved remission
What it is
This code identifies a monocytic leukemia that has not gone into remission. Use it when the record specifies an “other” monocytic leukemia and the disease remains active.
Clinical signs
Clinical features vary; refer to documentation. Common leukemia findings may include abnormal blood counts, fatigue, infections, bruising, or enlarged organs, but you should code only what is documented.
When to use this code
Use C93.Z0 when the provider documents other monocytic leukemia and explicitly states it has not achieved remission. It also applies when the record clearly shows persistent active disease after prior therapy. If remission status is not stated, check documentation before assigning this code.
Do not use for
Do not use this code for monocytic leukemia in remission, or when the leukemia type is not specified as “other” monocytic leukemia. Check documentation if the diagnosis is acute, chronic, or another leukemia subtype.
Coding tip
Confirm both the leukemia subtype and remission status in the provider note before coding.
