Other specified congenital malformations of urinary system

This code represents congenital anomalies of the urinary system that are not specifically classified elsewhere in ICD-10-CM. These are structural defects present at birth affecting organs such as the kidneys, ureters, bladder, or urethra, but which do not fit into more specific congenital malformation categories. Examples include congenital renal hypoplasia not otherwise specified, congenital ureteral stricture, or congenital bladder diverticulum.

Use this code when documentation clearly indicates a congenital malformation of the urinary system that is specified by the provider but lacks a more precise ICD-10-CM code. This code is appropriate for conditions such as congenital megaureter, congenital hydronephrosis without obstruction, or other specified but unlisted congenital urinary tract anomalies. Ensure the medical record explicitly states the congenital nature and the specific malformation.

• Do not use this code if a more specific congenital anomaly code for the urinary system is available (e.g., Q60.- for renal agenesis, Q61.- for cystic kidney disease).
• Always review documentation for laterality (e.g., left, right, bilateral) if applicable, as some related codes may require it.
• Confirm the anomaly is truly congenital; acquired conditions should be coded to their respective chapters.
