Malignant neoplasm of nipple and areola of male breast

This code signifies the presence of a cancerous tumor originating in the nipple or areola region of a male patient's breast. It specifically identifies a primary malignant growth within these structures, indicating an invasive or in situ carcinoma.

Use this code when documentation confirms a diagnosis of primary breast cancer localized to the nipple or areola in a male. This typically follows biopsy and pathological confirmation of malignancy. Supporting documentation would include pathology reports, physician notes detailing the location of the tumor, and imaging studies.

• Ensure the patient's gender is explicitly documented as male to support this specific code.
• Verify that the malignancy is primary to the nipple/areola and not a metastatic lesion from another site.
• Consider sequencing rules if other primary malignancies or complications are present.
