Malignant neoplasm of central portion of left female breast

This code signifies a cancerous tumor originating in the central part of the left breast, specifically the area surrounding the nipple and areola. It indicates a primary malignancy, meaning the cancer started in this location rather than spreading from another site.

Apply this code when documentation confirms a primary malignant neoplasm located in the central portion of the left breast. This typically follows a biopsy or imaging study (e.g., mammogram, MRI) confirming the diagnosis and precise anatomical location.

• Ensure laterality (left breast) and specific anatomical site (central portion) are clearly documented.
• Distinguish from other breast quadrants; if the tumor spans multiple quadrants, use the "overlapping lesion" code.
• Do not use for secondary malignancies or carcinoma in situ; specific codes exist for those conditions.
