2023 ICD-10-CM Diagnosis Code D47.2

Monoclonal gammopathy

    2016 2017 2018 2019 2020 2021 2022 2023 Billable/Specific Code
  • D47.2 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
  • The 2023 edition of ICD-10-CM D47.2 became effective on October 1, 2022.
  • This is the American ICD-10-CM version of D47.2 - other international versions of ICD-10 D47.2 may differ.
Applicable To
  • Monoclonal gammopathy of undetermined significance [MGUS]

    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
    2023 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.-)
    Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes
Approximate Synonyms
  • Benign monoclonal gammopathy
  • Hypogammaglobulinemia co-occurrent and due to monoclonal gammopathy of undetermined significance
  • Monoclonal gammopathy (clinical)
  • Monoclonal gammopathy of uncertain significance
  • Monoclonal gammopathy of undetermined significance w hypogammaglobulinemia
  • Monoclonal gammopathy, benign
  • Monoclonal gammopathy, undetermined significance
  • Monoclonal paraproteinemia
Clinical Information
  • A benign condition in which there is a higher-than-normal level of a protein called m protein in the blood. Patients with mgus are at an increased risk of developing cancer.
  • A laboratory test result indicating the presence of an abnormally high level of monoclonal immunoglobulins in the blood or urine.
  • A plasma cell disorder in which an abnormal amount of a single immunoglobulin is present in the serum. Up to 25% of cases of monoclonal gammopathy of undetermined significance (mgus) progress to a b-cell malignancy or myeloma. Mgus may occur in conjunction with various carcinomas, chronic inflammatory and infectious conditions, and other diseases.
  • Conditions characterized by the presence of m protein (monoclonal protein) in serum or urine without clinical manifestations of plasma cell dyscrasia.
ICD-10-CM D47.2 is grouped within Diagnostic Related Group(s) (MS-DRG v40.0):
  • 814 Reticuloendothelial and immunity disorders with mcc
  • 815 Reticuloendothelial and immunity disorders with cc
