Official Description

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

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 36583 refers to the complete replacement of a tunneled centrally inserted central venous access device, specifically a subcutaneous pump, through the same venous access site. This procedure is necessary when both the central venous catheter (CVC) and the subcutaneous pump are malfunctioning. The process begins with the examination of the existing device to determine the need for replacement. The procedure involves accessing the subcutaneous pocket where the pump is located, inspecting the catheter for any occlusions or damage, and utilizing a guidewire to facilitate the removal of the old catheter. A new catheter is then inserted, 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 the placement of the new catheter, a new subcutaneous pump is installed, and the connection between the catheter and the pump is tested for leaks. Finally, the subcutaneous pocket is closed, completing the replacement process. This code is specifically used when a pump is involved, distinguishing it from similar procedures that may involve a port instead.

1. Indications

The procedure associated with CPT® Code 36583 is indicated for patients who require the replacement of a malfunctioning tunneled centrally inserted central venous access device with a subcutaneous pump. The specific indications for this procedure include:

  • Malfunction of the Subcutaneous Pump - The pump may not be functioning correctly, necessitating its replacement to ensure continued access for medication delivery or other therapeutic interventions.
  • Occlusion or Damage to the Central Venous Catheter - The CVC may be obstructed or physically damaged, which can impede its function and require replacement to restore proper venous access.

2. Procedure

The procedure for CPT® Code 36583 involves several critical steps to ensure the successful replacement of the tunneled central venous access device:

  • Step 1: Accessing the Subcutaneous Pocket - The procedure begins with the surgeon making an incision to access the subcutaneous pocket where the pump is located. This allows for direct examination of the existing device.
  • Step 2: Inspecting the Catheter and Pump - Once the pocket is opened, the catheter is separated from the pump. Both the catheter and the pump are thoroughly inspected to confirm the need for replacement. If the pump is determined to be malfunctioning and the catheter is found to be occluded or damaged, the replacement process continues.
  • Step 3: Guidewire Placement - A guidewire is then inserted through the existing catheter. This guidewire serves as a pathway for the new catheter and is crucial for the safe removal of the old catheter.
  • Step 4: Catheter Removal - The old catheter is carefully withdrawn over the guidewire, ensuring that the venous access remains intact during the transition.
  • Step 5: Inserting the New Catheter - A new catheter is advanced over the guidewire, with careful attention to positioning the tip in one of the major veins, such as the subclavian, brachiocephalic, iliac vein, superior or inferior vena cava, or right atrium.
  • Step 6: Placing the New Pump - After the new catheter is in place, a new subcutaneous pump is inserted into the previously accessed pocket. This ensures that the patient has a functional device for medication delivery.
  • Step 7: Connecting and Testing for Leaks - The new catheter is then connected to the new pump. A test is performed by injecting intravenous fluid to check for any leaks at the connection site, ensuring the integrity of the system.
  • Step 8: Closing the Pocket - Finally, the subcutaneous pocket is closed, completing the procedure and securing the new device in place.

3. Post-Procedure

After the completion of the procedure, patients are typically monitored for any immediate complications related to the replacement of the central venous access device. Post-procedure care may include instructions on how to care for the insertion site, signs of infection to watch for, and guidelines for the use of the new pump. Patients may also be advised on follow-up appointments to ensure proper function of the new device and to address any concerns that may arise during the recovery period.

(for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79.
