Fibroadenosis of right breast

This code signifies a benign, non-cancerous condition of the right breast characterized by an overgrowth of fibrous and glandular tissue. It often presents as palpable lumps or generalized breast tenderness, typically fluctuating with hormonal changes.

Apply this code when documentation explicitly states fibroadenosis affecting the right breast. This diagnosis is commonly made after clinical examination, mammography, ultrasound, or biopsy confirming the benign nature of the tissue changes.

• Ensure laterality is clearly documented for the right breast; if bilateral, a different code is required.
• Distinguish from fibroadenoma (D24.1), which is a distinct benign tumor, not a diffuse condition.
• Do not use for unspecified fibrocystic changes; this code specifies fibroadenosis.
