Benign neoplasm of unspecified breast

This code signifies a non-cancerous growth or tumor found in the breast tissue, where the specific location within the breast is not documented. These benign neoplasms are typically slow-growing and do not metastasize to other parts of the body.

Apply this code when documentation confirms a benign breast neoplasm but lacks specificity regarding the quadrant or central portion of the breast. This is appropriate for pathology reports or imaging studies that identify a benign lesion without further anatomical detail.

• Avoid using this code if the laterality (left or right breast) is known; instead, use a more specific code from the D24 category.
• Do not use this code if the neoplasm is explicitly stated as malignant, in situ, or of uncertain behavior.
• Ensure the documentation clearly states "unspecified breast" or lacks any further anatomical detail to support this code.
