2020 ICD-10-CM Diagnosis Code D24

Benign neoplasm of breast

    2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
  • D24 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2020 edition of ICD-10-CM D24 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of D24 - other international versions of ICD-10 D24 may differ.
Type 2 Excludes
Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (D24) and the excluded code together.

    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
Clinical Information
  • A benign (not cancer) tumor that usually forms in the breast from both fibrous and glandular tissue. Fibroadenomas are the most common benign breast tumors.
  • A benign neoplasm originating from glandular cells with a fibrous or fibroblastic component.
  • A benign tumor of the breast characterized by the presence of stromal and epithelial elements. It presents as a painless, solitary, slow growing, firm, and mobile mass. It is the most common benign breast lesion. It usually occurs in women of childbearing age. The majority of fibroadenomas do not recur after complete excision. A slightly increased risk of developing cancer within fibroadenomas or in the breast tissue of patients previously treated for fibroadenomas has been reported.
  • A non-metastasizing neoplasm arising from the breast parenchyma.
  • A non-metastasizing tumor arising from the breast parenchyma.
