Fibroadenosis of breast

This code represents a benign condition of the breast characterized by an overgrowth of fibrous and glandular tissue, often resulting in palpable lumps, pain, or tenderness. It is a common cause of breast discomfort and is not considered a malignant or pre-malignant condition.

Use this code when documentation specifies fibroadenosis, fibrocystic changes, or benign mammary dysplasia of the breast. This diagnosis is typically made after clinical examination, imaging (mammogram, ultrasound), and sometimes biopsy to rule out malignancy.

• Differentiate from specific benign neoplasms like fibroadenoma (217).
• Ensure documentation clearly states "fibroadenosis" or "fibrocystic changes" rather than just "breast lump" without further specificity.
• Consider laterality if specified in the documentation, though ICD-9-CM 610.2 does not differentiate.
