Unspecified undescended testicle, unilateral

This code signifies a congenital anomaly where one testis has not descended into the scrotum, and the specific location of the undescended testis (e.g., abdominal, inguinal) is not documented. It represents a unilateral cryptorchidism of unknown or unspecified location.

Apply this code when documentation confirms a single undescended testicle, but the physician's notes do not specify whether it is in the abdomen, inguinal canal, or other ectopic location. This is appropriate when the laterality is known (unilateral) but the exact anatomical position is not.

• Only use this code when the specific location of the undescended testicle is truly unknown or unstated in the medical record.
• Avoid using this code if documentation specifies the location (e.g., Q53.11 for abdominal, Q53.12 for inguinal).
• Review operative reports or imaging studies carefully for more specific anatomical details before defaulting to "unspecified."
