In simple words: This procedure involves placing two tubes into large veins in your chest, through two separate entry points. These tubes are then passed under your skin. They are used for giving medications and nutrients or drawing blood, but they don't connect to a port or pump under your skin.

This code describes a procedure where two separate catheters are inserted into central veins through two different access points. The catheters are then tunneled under the skin. This procedure does not include a subcutaneous port or pump. An example of a catheter used in this procedure is the Tesio catheter.

Example 1: A patient with chronic kidney disease requires long-term hemodialysis and needs two separate central venous catheters placed for access, one for drawing blood and one for returning it after dialysis. A tunneled dual-lumen catheter without a port or pump is inserted., A patient with cancer requires frequent blood draws and chemotherapy infusions. To avoid multiple needle sticks and preserve peripheral veins, two tunneled central venous catheters are placed without a port or pump, providing separate access points for blood sampling and drug administration. , A patient undergoing a complex surgical procedure needs simultaneous monitoring of central venous pressure and delivery of multiple intravenous medications. Two tunneled central venous catheters are placed without a port or pump to accommodate these needs.

Documentation should include the type and size of catheters used, the insertion sites and tunneling technique, confirmation of the final catheter tip location (e.g., via x-ray), and any complications encountered during the procedure.
