Benign neoplasm of left epididymis

This diagnosis code signifies the presence of a non-cancerous tumor originating in the left epididymis, a coiled tube located at the back of the testicle that stores and carries sperm. These benign growths are typically slow-growing and do not metastasize to other parts of the body.

Use this code when documentation clearly identifies a benign neoplasm (e.g., adenoma, fibroma, lipoma) specifically located in the left epididymis. This diagnosis is often made following imaging studies (ultrasound, MRI) and confirmed by biopsy or surgical excision.

• Ensure laterality is explicitly documented as "left" to support this specific code.
• Distinguish from malignant neoplasms of the epididymis, which would be coded to the C63 series.
• Do not confuse with benign neoplasms of the testis or other adnexa, which have different codes.
