Benign neoplasm of breast (D24)
The ICD-10 code D24 and its subcodes identify benign neoplasms of the breast, which are noncancerous tumors found in breast tissue. These codes specify the location of the benign growth, such as the right breast (D24.1), left breast (D24.2), or an unspecified breast site (D24.9).
These codes are used to classify various benign breast tumors including common conditions like fibroadenomas and phyllodes tumors, as well as intraductal papillomas and adenomas of the nipple. For example, D24.1 covers benign tumors in the right breast and is linked to synonyms such as fibroadenoma and benign phyllodes neoplasm of the right breast. Similarly, D24.2 represents benign growths in the left breast with identical synonyms applying on the left side. The unspecified code D24.9 is used when the exact breast location is unknown or involves other areas such as the areola, nipple, or ectopic breast tissue. Understanding these synonyms helps medical coders accurately select the ICD-10 code for benign breast neoplasms from available clinical descriptions, ensuring precise documentation of benign breast conditions.

Type 2 Excludes
A type 2 excludes note represents "Not included here".
