Malig neoplasm of upper-inner quadrant of unsp male breast

This code signifies a cancerous tumor originating in the upper-inner quadrant of the breast tissue in a male patient, where the specific breast (left or right) is not documented. It indicates an invasive or in-situ malignancy affecting this particular anatomical region.

Use this code when medical record documentation confirms a malignant neoplasm in the upper-inner quadrant of a male breast, and the laterality (left or right) is not specified. This typically occurs following biopsy or imaging results confirming malignancy in this location without further laterality detail.

• Ensure the documentation explicitly states "male breast" and "upper-inner quadrant" for accurate assignment.
• Avoid using this code if laterality (left or right breast) is documented; instead, use the more specific C50.211 or C50.212.
• Always sequence this code as the primary diagnosis when it represents the reason for the encounter, unless a complication or metastasis is being treated.
