Malig neoplasm of upper-inner quadrant of right male breast

This code signifies a cancerous tumor originating in the upper-inner quadrant of the right breast in a male patient. This specific location refers to the superomedial portion of the breast tissue. It indicates a primary malignancy, not a metastatic lesion from another site.

Use this code when documentation confirms a primary malignant neoplasm located in the upper-inner quadrant of the right male breast. This diagnosis is typically established through biopsy and pathology reports. Applicable scenarios include initial diagnosis, treatment planning, and follow-up 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 specific quadrant (upper-inner) is documented; avoid using unspecified quadrant codes if this detail is available.
• Confirm this is a primary malignancy; if it's a secondary metastatic site, a different code from the C79 category would be appropriate.
