CPT® Code 51530

The procedure described by CPT® Code 51530 refers to a cystotomy performed specifically for the excision of a bladder tumor. A cystotomy is a surgical procedure that involves making an incision into the bladder, which is a hollow organ in the lower abdomen responsible for storing urine. The approach taken is a midline extraperitoneal abdominal approach, which allows the surgeon to access the bladder while minimizing disruption to surrounding structures. During the procedure, the rectus and transversalis fascia are carefully divided to create a pathway to the bladder. The incision is extended through the space of Retzius, a potential space located between the bladder and the pubic symphysis. Once access to the bladder is achieved, the anterior bladder wall and vesical neck are identified. The bladder dome, which is the upper part of the bladder, is incised to allow for inspection of the bladder wall, including critical areas such as the trigone, ureteral orifices, and bladder neck. The excision of the bladder tumor is performed with precision, ensuring that a margin of healthy tissue surrounding the tumor is also removed to reduce the risk of recurrence. After the tumor is excised, the resulting defect in the bladder wall is meticulously repaired using sutures to restore the integrity of the bladder. Finally, the bladder incision is closed, and the abdominal incision is closed in layers to promote proper healing and minimize complications.
