Malignant neoplasm of central portion of unsp male breast

This code signifies a cancerous tumor located in the central part of the breast tissue in a male patient, where the specific side (left or right) is not documented. It indicates an invasive or in situ malignancy originating in the nipple, areola, or immediately surrounding subareolar tissue.

Apply this code when documentation confirms a primary malignant neoplasm of the central portion of the male breast, and the laterality (left or right breast) is not specified. This is typically used when pathology reports confirm malignancy and the physician's notes do not differentiate the affected side.

• Ensure the documentation explicitly states "male breast" and "central portion."
• Avoid using this code if laterality (left or right breast) is documented; instead, use the more specific C50.111 or C50.112.
• Always sequence this code as the primary diagnosis when it represents the reason for the encounter, followed by any relevant secondary diagnoses.
