ICD-10 Code D24 – Benign neoplasm of breast (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D24 – Benign neoplasm of breast
What it is
D24 identifies a noncancerous tumor of the breast. Use it when documentation states a benign breast neoplasm, such as a fibroadenoma or other benign mass, and the record does not support malignancy.
Clinical signs
Clinical features vary; refer to documentation. Benign breast neoplasms are often described as a palpable, well-circumscribed breast lump or an imaging-detected mass with benign characteristics.
When to use this code
Use D24 when the provider documents a benign breast tumor or mass and pathology, imaging, or assessment supports a nonmalignant diagnosis. It also fits when the chart specifically names a benign neoplasm of the breast. If the documentation is unclear about laterality or pathology, check documentation before coding.
Do not use for
Do not use D24 for malignant breast neoplasms, benign breast cysts, or nonspecific breast pain alone. If the record describes a lesion without confirming benign neoplasm, check documentation.
Coding tip
Code D24 only when the provider clearly documents a benign breast neoplasm, not just an unspecified breast lump.
