CPT® Code 36597

The CPT® Code 36597 refers to the procedure of repositioning a previously placed central venous catheter (CVC) under fluoroscopic guidance. A central venous catheter is a long, thin tube that is inserted into a large vein, typically in the neck, chest, or groin, to administer medication, fluids, or to obtain blood samples. In this procedure, it is identified that the tip of the CVC is not in the correct position, which can lead to complications such as inadequate drug delivery or increased risk of thrombosis. To address this issue, a chest radiograph is obtained to visualize the catheter's placement. If the CVC is found to be improperly positioned, the physician will remove any sutures that are anchoring the catheter to the skin. Following this, the physician will manipulate the catheter tip into the correct location while utilizing fluoroscopic guidance, which provides real-time imaging to ensure accurate repositioning. Once the catheter is in the desired position, it is secured back in place with sutures, and a dressing is applied to protect the insertion site. This procedure is essential for ensuring the proper functioning of the central venous catheter and minimizing potential complications associated with misplacement.
