Benign neoplasm of left breast

This code signifies the presence of a non-cancerous growth or tumor originating in the glandular or stromal tissue of the left breast. These benign neoplasms are typically slow-growing and do not metastasize to other parts of the body.

Use this code when diagnostic imaging (e.g., mammogram, ultrasound, MRI) or biopsy confirms a benign mass located specifically in the left breast. Documentation should clearly state "benign neoplasm" or a specific benign tumor type (e.g., fibroadenoma, intraductal papilloma) and its laterality.

• Ensure documentation specifies "left breast" as laterality is crucial for accurate coding.
• Do not use this code for malignant neoplasms; refer to the C50.- series for breast cancer.
• If the neoplasm is unspecified as to benign or malignant, refer to the D48.6 category.
