Anomalies of urachus

This code represents congenital abnormalities of the urachus, a fetal remnant connecting the bladder to the umbilicus. These anomalies can include a patent urachus (a persistent open connection), urachal cyst, urachal sinus, or urachal diverticulum. These conditions typically involve incomplete closure or degeneration of the urachus.

Use this code when documentation specifies a congenital anomaly of the urachus, such as a patent urachus identified in an infant or child, or an adult presenting with symptoms related to a urachal cyst or sinus. Supporting documentation should clearly identify the specific urachal anomaly.

• Differentiate between congenital anomalies (this code) and acquired conditions affecting the bladder or umbilical region.
• Ensure the documentation specifies "urachus" as the affected structure; do not use for general umbilical or bladder anomalies without this specificity.
• Consider additional codes for any associated symptoms or complications, such as infection of a urachal cyst.
