2023 ICD-10-CM Diagnosis Code C94.8

Other specified leukemias

    2016 2017 2018 2019 2020 2021 2022 2023 Non-Billable/Non-Specific Code
  • C94.8 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2023 edition of ICD-10-CM C94.8 became effective on October 1, 2022.
  • This is the American ICD-10-CM version of C94.8 - other international versions of ICD-10 C94.8 may differ.
Applicable To
  • Aggressive NK-cell leukemia
  • Acute basophilic leukemia

    2023 ICD-10-CM Range C00-D49

    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).

      2016 2017 2018 2019 2020 2021 2022 2023 Non-Billable/Non-Specific Code
    Type 1 Excludes
    • leukemic reticuloendotheliosis (C91.4-)
    • myelodysplastic syndromes (D46.-)
    • personal history of leukemia (Z85.6)
    • plasma cell leukemia (C90.1-)
    Other leukemias of specified cell type
Clinical Information
  • A rare acute myeloid leukemia in which the primary differentiation is to basophils. It is characterized by an extreme increase of immature basophilic granulated cells in the bone marrow and blood. Mature basophils are usually sparse.
  • A rare, highly aggressive, epstein-barr virus-associated leukemia, also known as aggressive nk-cell leukemia/lymphoma; it may represent the leukemic counterpart of nasal type extranodal nk/t-cell lymphomas. It affects primarily teenagers and young adults. It is characterized by the systemic proliferation of nk cells in the peripheral blood, bone marrow, liver, and spleen.
  • An acute myeloid leukemia in which the immature cells differentiate towards basophils. This is a rare leukemia. The observed cases have been associated with a poor prognosis. The term basophilic leukemia is used as a synonym for acute basophilic leukemia. Chronic basophilic leukemia is an inappropriate term vaguely connected to the term mast cell leukemia. (who, 2001)
