Acute monoblastic/monocytic leukemia

    2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
  • C93.0 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.

  • This is the American ICD-10-CM version of C93.0 - other international versions of ICD-10 C93.0 may differ.

    Neoplasms

    Note
    • Functional activity
    • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
    • Morphology [Histology]
    • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
    • Primary malignant neoplasms overlapping site boundaries
    • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
    • Malignant neoplasm of ectopic tissue
    • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).
    Neoplasms
  • C81-C96
    2020 ICD-10-CM Range C81-C96

    Monocytic leukemia

      2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
    Includes
    • monocytoid leukemia
    Type 1 Excludes
    • personal history of leukemia (Z85.6)
    Monocytic leukemia
Clinical Information
  • Acute myeloid leukemia in which 80% or more of the leukemic cells are of monocytic lineage. Bleeding disorders are common presenting features. It usually follows an aggressive clinical course. (who, 2001)
  • An acute myeloid leukemia in which 80% or more of the leukemic cells are of monocytic lineage including monoblasts, promonocytes, and monocytes.
  • An acute myeloid leukemia in which the monoblasts represent 80% or more of the total cellular population. (who, 2001)
  • Uncommon form of acute myelogenous leukemia, in which the predominating cells are identified as monocytes; a few myelocytes may be present, but not as many as in acute myelomonocytic leukemia.
Code History
  • 2016 (effective 10/1/2015): New code (first year of non-draft ICD-10-CM)
  • 2017 (effective 10/1/2016): No change
