Malignant neoplasm of central portion of right male breast

This code signifies a cancerous tumor originating in the central part of the right breast in a male patient. This typically involves the subareolar region, which is the area directly beneath the nipple and areola. It represents a primary malignancy, not a metastatic lesion from another site.

Apply this code when documentation confirms a primary malignant neoplasm located in the central portion of the right male breast. This diagnosis is typically supported by pathology reports confirming malignancy and imaging studies (e.g., mammogram, ultrasound) localizing the tumor to the central right breast. Use for initial encounters, active treatment, or surveillance following treatment for this specific cancer.

• Ensure the documentation explicitly states "male breast" and "right breast" to differentiate from female breast cancer or left-sided involvement.
• Verify the tumor's location as "central portion" or "subareolar" to avoid miscoding to other quadrants.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless a complication of the neoplasm is being treated.
