CPT® Code 50526

The procedure described by CPT® Code 50526 involves the closure of a nephrovisceral fistula, which is an abnormal connection between the kidney and another internal organ, such as the colon. This condition often arises due to complications from renal stones, infections like tuberculosis, or injuries sustained during medical procedures such as percutaneous interventions or lithotripsy. The closure of the fistula is performed through a thoracic surgical approach, which is determined by the specific location of the fistulous tract. During the procedure, the kidney and ureter are surgically exposed, allowing for direct access to the fistula. A catheter is inserted into the ureter, and a radiopaque contrast agent is injected to visualize the fistulous tract clearly. The surgeon then meticulously traces the fistula to its entry point into the affected organ, where it is securely ligated and divided. Following this, the involved organ is repaired as necessary, and the origin of the fistula within the kidney is also closed to prevent any further complications. It is important to note that for an abdominal approach to this procedure, CPT® Code 50525 should be used, while CPT® Code 50526 is specifically designated for the thoracic approach.
