2019 ICD-10-CM Diagnosis Code D47.0

Mast cell neoplasms of uncertain behavior

    2016 2017 2018 - Converted to Parent Code 2019 Non-Billable/Non-Specific Code
  • D47.0 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2019 edition of ICD-10-CM D47.0 became effective on October 1, 2018.
  • This is the American ICD-10-CM version of D47.0 - other international versions of ICD-10 D47.0 may differ.
Type 1 Excludes
Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as D47.0. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

    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
  • D37-D48
    2019 ICD-10-CM Range D37-D48

    Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes

    Note
    • Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.
    Type 1 Excludes
    • neoplasms of unspecified behavior (D49.-)

Approximate Synonyms
  • Mastocytoma
  • Neoplasm of uncertain behavior, histiocytic or mas
  • Neoplasm of uncertain behavior, histiocytic or mast cell
Clinical Information
  • A form of systemic mastocytosis in which patients experience no pain. It is characterized by the multifocal mast cell filtrates, mostly in skin and bone marrow (<20% mast cells). It has a low cytomorphological grade.
  • A growth or lump of mast cells (a type of white blood cell). Mast cell tumors can involve the skin, subcutaneous tissue, and muscle tissue.
  • A heterogeneous group of disorders characterized by the abnormal growth and accumulation of mast cells in one or more organ systems. Recent data suggest that most variants of mastocytosis are clonal disorders. (who, 2001)
  • A localized tumor composed of sheets of mast cells without atypia. It includes the cutaneous mastocytoma which involves the dermis and subcutaneous tissue, and the extracutaneous mastocytoma. Most cases of extracutaneous mastocytoma have been reported in the lung.
  • A neoplasm composed of mast cells, for which the malignancy status has not been determined.
  • An indolent mast cell neoplasm characterized by systemic infiltration of skin and internal organs by aggregates of neoplastic mast cells.
  • An indolent mast cell neoplasm characterized by systemic infiltration of skin and internal organs by aggregates of neoplastic mast cells. There is no evidence of mast cell leukemia or clonal hematologic malignancy. Clinically, there is no evidence of palpable hepatomegaly and splenomegaly, malabsorption syndrome, or pathologic fractures.
  • Nodular cutaneous mast cell infiltrate, which is usually present at birth or soon after as a solitary nodule, although three to four lesions may occur; lesions typical of urticaria pigmentosa may occur later.
