CPT® Code 51520

The CPT® Code 51520 refers to a surgical procedure known as cystotomy, specifically for the simple excision of the vesical neck, which is classified as a separate procedure. This operation involves a midline extraperitoneal abdominal approach to access the bladder. During the procedure, the surgeon makes an incision that divides the rectus and transversalis fascia, allowing access through the space of Retzius. The anterior wall of the bladder and the vesical neck are then identified. The bladder dome is incised to inspect the bladder wall, including critical areas such as the trigone, ureteral orifices, and bladder neck. The primary objective of this procedure is to excise the bladder neck, which is mobilized and resected. Following the excision, the visceral bladder fascia is utilized to reconstruct the neck, ensuring proper healing and function of the bladder. This procedure is distinct from other related procedures, such as those involving the excision of bladder diverticula or tumors, which are coded separately under CPT® Codes 51525 and 51530, respectively. The clear delineation of this procedure is essential for accurate medical coding and billing, as it specifies the surgical intervention performed on the bladder neck without involving additional complexities associated with diverticula or tumors.
