Malignant neoplasm of right epididymis

This code identifies a primary cancerous tumor originating in the right epididymis, a coiled tube located at the back of the testicle that stores and carries sperm. This is a rare form of male genitourinary cancer.

Assign this code when documentation confirms a primary malignant neoplasm specifically located in the right epididymis. This diagnosis is typically established through biopsy and histopathological examination.

• Ensure laterality is clearly documented as "right" to support this specific code.
• Distinguish from secondary malignant neoplasms or benign tumors of the epididymis.
• Code any associated metastatic sites separately.
