Malignant neoplasm of nipple and areola, right male breast

This code signifies a primary cancerous tumor originating in the nipple or areola region of the right breast in a male patient. It indicates a malignant growth, meaning it has the potential to invade surrounding tissues and metastasize.

Apply this code when documentation confirms a biopsy-proven or clinically diagnosed primary malignant neoplasm specifically located in the nipple or areola of the right male breast. This code is appropriate for initial encounters, active treatment, and surveillance for the primary site.

• Ensure the documentation clearly specifies "male breast" and the exact location as "nipple and areola" on the "right" side.
• Do not use this code for benign lesions, secondary malignancies, or neoplasms of other specified or unspecified parts of the male breast.
• Always sequence this code as the primary diagnosis when the malignancy is the reason for the encounter, followed by codes for any associated symptoms or complications.
