Official Description

Insertion of tunneled centrally inserted central venous access device, with subcutaneous port; age 5 years or older

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 36561 involves the insertion of a tunneled centrally inserted central venous access device (CVC) that includes a subcutaneous port, specifically for patients aged 5 years or older. A central venous catheter is a flexible tube that is inserted into a large vein in the body, allowing for the administration of medications, fluids, or for drawing blood. The term "tunneled" refers to the method of placement, where the catheter is inserted through a subcutaneous tunnel, which helps to reduce the risk of infection and provides a more stable access point. The catheter must terminate in one of several large veins, such as the subclavian, brachiocephalic, or iliac veins, or in the superior or inferior vena cava, or the right atrium of the heart. The most common site for accessing the venous system for this procedure is the jugular vein, although the subclavian and femoral veins may also be used. The procedure typically involves the use of local anesthesia at the puncture site to minimize discomfort. The Seldinger technique is employed to facilitate the insertion of the catheter, which involves puncturing the skin and vein with a needle, followed by the insertion of a guidewire. This guidewire serves as a pathway for the catheter, which is then advanced into the central venous system. The placement of the catheter is confirmed through imaging guidance, which may be reported separately. The subcutaneous port is then secured in a pocket created under the skin, allowing for easy access to the central venous system for future treatments or blood draws.

1. Indications

The insertion of a tunneled centrally inserted central venous access device with a subcutaneous port is indicated for patients who require long-term venous access for various medical treatments. The following conditions may warrant this procedure:

  • Long-term medication administration Patients requiring ongoing intravenous medications, such as chemotherapy or long-term antibiotics, benefit from a reliable venous access point.
  • Frequent blood draws Individuals who need regular blood sampling for laboratory tests may require a central venous access device to minimize repeated venipunctures.
  • Fluid management Patients with conditions that necessitate frequent fluid administration, such as those with dehydration or electrolyte imbalances, may require this type of access.
  • Parenteral nutrition Patients unable to consume food orally or through enteral feeding may need central venous access for total parenteral nutrition (TPN).

2. Procedure

The procedure for inserting a tunneled centrally inserted central venous access device with a subcutaneous port involves several detailed steps:

  • Preparation and Anesthesia The patient is positioned appropriately, and the planned puncture site is cleaned and sterilized. Local anesthesia is administered at the site to ensure the patient experiences minimal discomfort during the procedure.
  • Venous Access Utilizing the Seldinger technique, a needle is inserted into the jugular vein, puncturing both the skin and the vein. Once the needle is in place, a guidewire is threaded through the needle and advanced several centimeters into the vein.
  • Creating the Subcutaneous Pocket A subcutaneous pocket is created at the site where the port will be placed. This involves making an incision in the skin and dissecting the tissue to form a suitable space for the port.
  • Creating the Tunnel A subcutaneous tunnel is then formed from the venous access site to the newly created pocket. This tunnel allows the catheter to be routed from the vein to the port without being exposed to the external environment.
  • Catheter Insertion An introducer sheath and dilator are advanced over the guidewire into the jugular vein. The guidewire and dilator are then removed, and the catheter is advanced through the tunnel to the introducer sheath, ensuring it reaches the central venous system.
  • Placement Confirmation The correct placement of the catheter is verified through imaging guidance, which may involve taking radiographs to ensure the catheter tip is positioned appropriately in the central vein.
  • Connecting the Port The catheter is connected to the subcutaneous port, which is then placed securely in the subcutaneous pocket. This allows for easy access to the central venous system for future treatments.
  • Closure The incision over the venous access site is closed, and the port is sutured into place. The pocket is also closed to ensure that the port remains secure and protected.

3. Post-Procedure

After the procedure, the patient is monitored for any immediate complications, such as bleeding or infection at the insertion site. Instructions for care of the insertion site and the port are provided, including how to keep the area clean and signs of potential complications to watch for. Patients may be advised on activity restrictions to ensure proper healing. Follow-up appointments are typically scheduled to assess the function of the device and to perform any necessary maintenance or adjustments.
