Malignant neoplasm of central portion of left male breast

This code signifies a primary cancerous tumor originating in the central area of the left breast in a male patient. This central portion typically includes the nipple and areola complex, as well as the underlying breast tissue. It represents an invasive malignancy, not a benign growth or carcinoma in situ.

Use this code when documentation explicitly states a primary malignant neoplasm located in the central portion of the left breast in a male. This diagnosis is typically confirmed by biopsy and pathology reports. It is appropriate for initial encounters for diagnosis and treatment, as well as for subsequent encounters related to the management of this specific primary malignancy.

• Ensure the documentation specifies "male breast" and "left" side, as well as "central portion."
• Distinguish from other specified or unspecified sites within the male breast; precise anatomical location is key.
• Do not use for carcinoma in situ (D05.-) or secondary malignant neoplasms (C79.81).
