Malignant neoplasm of descended right testis

This code signifies a primary cancerous tumor originating in the right testis, specifically when the testis has descended into the scrotum. It indicates a malignant neoplastic process affecting the right gonadal tissue.

Apply this code when documentation confirms a primary malignant neoplasm of the right descended testis, typically diagnosed via biopsy or orchiectomy. Supporting documentation should clearly specify the laterality and the malignant nature of the testicular mass.

• Ensure documentation specifies "right" testis and confirms malignancy.
• Do not use for undescended testes; separate codes exist for those scenarios.
• Sequence as the primary diagnosis when the testicular cancer is the reason for the encounter.
