Malignant neoplasm of nipple and areola, left female breast

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

Apply this code when documentation confirms a primary malignant tumor located in the nipple or areola of the left female breast. This diagnosis is typically established through biopsy and pathology reports.

• Ensure laterality is accurately documented and reflected in the code selection (left breast).
• Distinguish between primary and secondary malignancies; this code is for a primary tumor.
• Confirm the specific anatomical site (nipple/areola) to avoid miscoding with other breast quadrants.
