Benign neoplasm of left kidney

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

Apply this code when documentation clearly indicates a benign tumor located specifically in the left kidney. This diagnosis is often made following imaging studies (e.g., CT scan, MRI) and may be confirmed by biopsy.

• Ensure the documentation specifies "left" kidney; if laterality is not documented, query the provider.
• Distinguish carefully from malignant neoplasms of the kidney (C64.2) or neoplasms of uncertain behavior (D41.02).
• Do not use for cysts or other non-neoplastic lesions of the kidney.
