Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q64 range.
Epispadias
A birth defect due to malformation of the URETHRA in which the urethral opening is above its normal location. In the male, the malformed urethra generally opens on the top or the side of the PENIS, but the urethra can also be open the entire length of the penis. In the female, the malformed urethral opening is often between the CLITORIS and the labia, or in the ABDOMEN.
Posterior Urethral Valve
A developmental abnormality characterized by the presence of an obstructing membrane in the posterior urethra of the male newborn. It results in bladder obstruction.
Supravesical Fissure of Urinary Bladder
A urogenital anomaly characterized by infraumbilical exstrophy of a bladder open only in its upper portion and pubic diastasis. It has been described in both males and females and may be associated with trisomy 18, omphalocele, and urethral duplication.
About the Q64 Code Range
These are urinary-system differences present at birth, affecting structures such as the bladder and the urethra, the tube that carries urine out.
Within Q64, subdivisions distinguish conditions involving the bladder, urethra, and urinary opening. Q64.3 separates bladder-neck obstruction from narrowing of the urethra or urinary opening. Q64.7 includes separate codes for a double urethra, a double urinary opening, and other or unspecified malformations. The category also distinguishes other specified malformations from those left unspecified.
