Fibroadenosis of unspecified breast

This code describes a benign, non-cancerous condition of the breast characterized by an overgrowth of fibrous and glandular tissue, leading to palpable lumps, tenderness, or pain. It represents a general diagnosis of fibroadenosis when the specific type (e.g., sclerosing, cystic) is not documented.

Use this code when the physician's documentation confirms a diagnosis of fibroadenosis but does not specify the particular histological subtype or laterality. This is appropriate for initial diagnoses or follow-up when further specificity is not available or not yet determined.

• Do not use this code if the documentation specifies a particular type of fibroadenosis (e.g., N60.1- for diffuse cystic mastopathy).
• Always query the provider for laterality (left, right, bilateral) if not documented, as more specific codes exist (N60.21, N60.22, N60.23).
• This code should not be used for a fibroadenoma, which is a distinct benign tumor (D24.-).
