Malignant neoplasm of nipple and areola, right female breast

This code identifies a primary cancerous tumor originating in the nipple or areola of the right female breast. This malignancy is characterized by uncontrolled cell growth in these specific breast tissues. It indicates the initial diagnosis of cancer in this location, not a metastatic spread from another site.

Use this code for female patients diagnosed with a primary malignant neoplasm confined to the nipple or areola of the right breast. Documentation must clearly specify the right side and the involvement of the nipple and/or areola, often confirmed by biopsy or imaging. This code is appropriate for initial diagnosis and treatment planning.

• Always confirm laterality (right vs. left) and the specific anatomical site (nipple/areola) from the pathology report or physician's documentation.
• Do not use this code for malignancies of other parts of the breast; refer to codes within the C50.1-C50.6 range for other breast quadrants or central portions.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any relevant codes for treatment or complications.
