Hypoplasia of testis and scrotum

This code describes a congenital condition characterized by the underdevelopment or incomplete formation of one or both testes and/or the scrotum. This can result in smaller than normal testes (testicular hypoplasia) and/or an underdeveloped scrotal sac. It is a birth defect affecting male reproductive organs.

Use this code when documentation clearly indicates congenital hypoplasia of the testis and/or scrotum. This diagnosis is typically made during infancy or childhood upon physical examination or imaging studies. Supporting documentation should specify the hypoplastic nature of the testis and/or scrotum.

• Differentiate from cryptorchidism (undescended testis) where the testis is present but not in the scrotum.
• Specify laterality if documented (e.g., unilateral vs. bilateral).
• Consider additional codes for associated congenital anomalies if present.
