CPT® Code 46748

Repair of cloacal anomaly by anorectovaginoplasty and urethroplasty, combined abdominal and sacroperineal approach; with vaginal lengthening by intestinal graft or pedicle flaps

The CPT® Code 46748 refers to the surgical procedure known as the repair of a cloacal anomaly through anorectovaginoplasty and urethroplasty, utilizing a combined abdominal and sacroperineal approach. Cloacal anomalies are congenital defects that occur exclusively in females, characterized by the abnormal merging of the rectum, vagina, and urethra into a single common channel. The complexity of the surgical repair is determined by the specific type of cloacal anomaly present, as well as the precise location where the rectum, vagina, and urethra converge. This procedure is particularly indicated for high cloacal anomalies, which necessitate a more intricate surgical approach compared to low cloacal anomalies. In this procedure, the surgeon employs both abdominal and sacroperineal techniques to access and repair the affected structures. The surgical intervention involves mobilizing the rectum, vagina, and urethra, followed by the construction of functional openings in the perineum through vaginoplasty and urethroplasty. A unique aspect of this procedure is the vaginal lengthening, which can be achieved either by using an intestinal graft or by employing pedicle flaps from adjacent tissues. This approach is critical for ensuring that the vaginal canal is adequately lengthened to allow for normal anatomical function. The detailed steps involved in the procedure are essential for medical coders and billers to understand, as they provide the necessary context for accurate coding and billing practices related to this complex surgical intervention.
