Unilateral intraabdominal testis

This code describes a condition where a single testis has not descended into the scrotum and remains located within the abdominal cavity. This is a form of cryptorchidism, specifically unilateral, meaning only one side is affected, and the undescended testis is situated inside the abdomen.

Use this code when documentation clearly indicates a diagnosis of an undescended testis that is located intra-abdominally on one side. This diagnosis is typically made during physical examination, imaging studies (e.g., ultrasound, MRI), or during surgical exploration for cryptorchidism.

• Differentiate from inguinal cryptorchidism (Q53.12-) or unspecified intra-abdominal cryptorchidism (Q53.10).
• Ensure laterality is clearly documented (left, right, or unspecified) as specific codes exist for each.
• Do not use if the testis is absent (anorchia) or ectopic (located outside the normal path of descent but not intra-abdominal).
