Monocytic leukemia (C93)

ICD-10 code C93 and its subcodes are specifically used to classify different forms of monocytic leukemia, a group of rare blood cancers affecting monocytes, a type of white blood cell. These codes distinguish between acute, chronic, juvenile, and unspecified types, as well as the disease’s status, such as remission or relapse.

The ICD-10 code for monocytic leukemia covers various detailed diagnoses. For example, C93.00 and C93.01 refer to “acute monoblastic/monocytic leukemia,” also known as acute monocytic leukemia, indicating whether the disease is active or in remission. Chronic forms like chronic myelomonocytic leukemia use codes C93.10 and C93.11, linked to myelodysplastic/myeloproliferative disorders. Juvenile types, identified by C93.30 series, address conditions seen in children, including “juvenile myelomonocytic leukemia.” Unspecified and other monocyte leukemias have distinct codes to pinpoint their stage and classification. These codes help healthcare providers and coders accurately document the leukemia subtype and treatment status, essential for patient care, research, and billing.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • monocytoid leukemia

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
