CPT® Code 36582

Replacement, complete, of a tunneled centrally inserted central venous access device, with subcutaneous port, through same venous access

The CPT® Code 36582 refers to the complete replacement of a tunneled centrally inserted central venous access device, specifically one that includes a subcutaneous port, through the same venous access site. This procedure is typically indicated when there is a malfunction of both the port or pump and the central venous catheter (CVC). The process begins with the verification of the CVC's tip position through separate radiographic imaging. During the procedure, the subcutaneous pocket is accessed, and the existing catheter is detached from the port or pump. A thorough examination of the port or pump is conducted to confirm the need for replacement. If the port or pump is deemed defective, it is removed, and the catheter is inspected for any occlusions or damage. A guidewire is then introduced through the existing catheter, which is subsequently withdrawn over the guidewire. A new catheter is advanced over the guidewire, ensuring that its tip is correctly positioned in one of the major veins, such as the subclavian, brachiocephalic, iliac vein, superior or inferior vena cava, or right atrium. Following this, a new port or pump is placed in the subcutaneous pocket, and the new catheter is connected to the port or pump device. The connection is tested for leaks using intravenous fluid before the pocket is closed. This procedure is essential for maintaining effective venous access for patients requiring long-term intravenous therapy.
