4.4 Congenital Malformations of Genital Organs

Hypospadias (Q54, Q54.0, Q54.1, Q54.2, Q54.3, Q54.4, Q54.8, Q54.9)

Displacement of the urethral meatus ventrally and proximally from the tip of the penis. It is classified according to the position of the meatus on the penis:

  • First degree (Q54.0): the urethral meatus is located on either the glans (glanular hypospadias) or the corona (coronal hypospadias).
  • Second degree (Q54.1): the urethral meatus is located in the balanopenile furrow or coronal sulcus (subcoronal hypospadias) or in the shaft of the penis (distal penile, midshaft, and proximal penile hypospadias).
  • Third degree (Q54.2, Q54.3): the urethral meatus is located in the junction of the penis and the scrotum (penoscrotal or scrotal hypospadias) or the perineum (perineoscrotal, perineal, or pseudovaginal hypospadias).

The shortening of the ventral side of the penis found in hypospadias can result in a penile curvature, known as chordee. This is present more commonly in severe cases, but also can occur independently of hypospadias.
