Malignant neoplasm of nipple and areola of female breast

This code signifies a primary cancerous tumor originating in the nipple or areola region of a female patient's breast. It specifically identifies the malignant growth within these distinct anatomical structures of the breast.

Apply this code when documentation confirms a primary malignant neoplasm localized to the nipple or areola. This diagnosis is typically established through biopsy and pathology reports. Use for initial encounters and subsequent treatment of this specific breast cancer site.

• Ensure documentation clearly specifies the nipple or areola as the primary site, not just "breast."
• Do not use for secondary or metastatic neoplasms; this code is for the primary tumor.
• Consider laterality (left, right, or unspecified) if available in the documentation, though not explicitly required by this specific ICD-9 code.
