Cecoureterocele

This code describes a congenital anomaly where the distal ureter prolapses into the bladder, forming a cyst-like dilation within the bladder lumen. This condition is typically associated with a duplicated collecting system, where the ureter draining the upper pole of the kidney inserts ectopically into the bladder.

Assign this code when documentation explicitly states a diagnosis of cecoureterocele, often identified during prenatal ultrasound or postnatal imaging for urinary tract infections or hydronephrosis. Supporting documentation will include imaging reports (e.g., ultrasound, VCUG, CT urogram) confirming the presence and location of the ureterocele.

• Differentiate from simple ureterocele (Q62.31) which does not involve prolapse into the bladder.
• Always review imaging reports and operative notes for precise anatomical descriptions.
• Code any associated conditions, such as hydronephrosis (N13.x) or duplicated collecting system (Q62.7), as additional diagnoses.
