Ectopic testis, unilateral

This code represents a congenital anomaly where one testis has not descended into the scrotum and is located outside its normal pathway. This condition is also known as unilateral cryptorchidism, specifically when the testis is found in an ectopic location rather than an undescended but normally located position.

Use this code for patients diagnosed with a single ectopic testis, meaning the testis is located in an abnormal position (e.g., superficial inguinal pouch, perineum, femoral canal, or contralateral hemiscrotum). Documentation should clearly specify "ectopic" and "unilateral" to support its use.

• Differentiate from undescended testis (cryptorchidism) where the testis is along the normal path of descent but has not reached the scrotum.
• Ensure documentation specifies laterality (unilateral vs. bilateral); this code is for unilateral involvement only.
• Consider additional codes for any associated complications or surgical interventions (e.g., orchiopexy).
