CPT® Code 36578

Replacement, catheter only, of central venous access device, with subcutaneous port or pump, central or peripheral insertion site

The CPT® Code 36578 refers to the procedure of replacing a catheter only for a central venous access device that includes a subcutaneous port or pump, which can be inserted through either a central or peripheral site. This procedure is essential for patients who require long-term venous access for therapies such as chemotherapy, total parenteral nutrition, or frequent blood draws. During the catheter replacement, the existing catheter is carefully evaluated for any occlusions or damage, ensuring that the integrity of the venous access is maintained. The subcutaneous pocket, where the port or pump resides, is surgically opened to allow for inspection and replacement of the catheter. The procedure involves the use of a guidewire to facilitate the removal of the old catheter and the insertion of a new one, ensuring that the catheter tip is correctly positioned in a major vein, such as the subclavian, brachiocephalic, iliac vein, superior or inferior vena cava, or right atrium. This meticulous process is crucial for maintaining effective venous access and preventing complications associated with catheter malfunction or infection.
