Specific Coding for Benign neoplasm of breastOverview

Non-specific codes like D24 require more characters. Use one of these billable codes instead:

  • Use D24.1 for Benign neoplasm of right breast

  • Use D24.2 for Benign neoplasm of left breast

  • Use D24.9 for Benign neoplasm of unspecified breast

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D24: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • benign neoplasm of connective tissue of breast
  • benign neoplasm of soft parts of breast
  • fibroadenoma of breast

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

  • adenofibrosis of breast (N60.2)
  • benign cyst of breast (N60.-)
  • benign mammary dysplasia (N60.-)
  • benign neoplasm of skin of breast (D22.5, D23.5)
  • fibrocystic disease of breast (N60.-)

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • 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).

    benign neoplasm of connective tissue of breast (D24.-)

Excludes2 1

These codes carry an Excludes2 note naming D24: its condition is not part of those codes, and both may be reported when the patient has both.

Clinical InformationClinical

  • Benign Breast Neoplasm

    a neoplasm that arises from the breast and is characterized by the absence of atypical or malignant cytological and architectural features, and absence of invasive features or metastatic potential.

Patient EducationClinical

Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.
