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.
About the Q64 Code Range
ICD-10 code Q64 covers a range of congenital malformations affecting the urinary system, including the bladder, urethra, and related structures. These codes specifically identify various birth defects such as epispadias, bladder exstrophy, urethral strictures, and other rare structural malformations.
This section helps medical coders and healthcare professionals precisely document conditions like epispadias (Q64.0), also known as exstrophy epispadias complex in males and females, or exstrophy of the urinary bladder (Q64.1), including its subtypes such as cloacal exstrophy (Q64.12). It also includes congenital narrowings or blockages such as posterior urethral valves (Q64.2) and congenital bladder neck obstruction (Q64.31). Codes like Q64.4 cover malformations of the urachus, while Q64.5 tracks rare cases of congenital absence of bladder and urethra. More complex conditions, such as double urethra (Q64.74) or congenital urethrorectal fistula (Q64.73), are captured here as well. This detailed classification permits accurate identification and coding of diverse urinary tract congenital anomalies for appropriate clinical documentation and billing. Understanding synonyms like exstrophy of urinary bladder sequence or urethroperineal fistula facilitates correct code selection when encountering various terminologies in clinical records.
