36561

Insertion of Tunneled Central Venous Access Device with Subcutaneous Reservoir; Age 5 Years or Older

CPT 36561 describes the surgical insertion of a tunneled central venous access device (CVAD) that includes a subcutaneous reservoir, commonly referred to as an implantable port, in patients who are 5 years of age or older. This complex procedure involves the placement of a catheter into a major vein, typically the internal jugular, subclavian, or femoral vein, which is then tunneled under the skin to a separate site where a subcutaneous pocket is created. The catheter is connected to a reservoir (the port) that is surgically secured within this pocket, usually located on the upper chest or occasionally the abdomen. The reservoir allows for repeated access to the venous system via a specialized needle (Huber needle) through the skin. The tunneling component of the procedure is a critical clinical feature, as it provides a physical barrier between the skin exit site and the venous entry point, significantly reducing the long-term risk of catheter-related bloodstream infections compared to non-tunneled catheters. The procedure is typically performed under sterile conditions in an operating room or interventional radiology suite, often utilizing ultrasound guidance for initial venous puncture and fluoroscopic guidance to ensure the distal tip of the catheter is correctly positioned at the cavoatrial junction (the junction of the superior vena cava and the right atrium). This device is intended for long-term use, often lasting months or years, for patients requiring frequent or continuous infusion therapy such as chemotherapy, total parenteral nutrition, or long-term antibiotic administration.

Clinical Indications

  • Administration of long-term chemotherapy for malignancy
  • Requirement for long-term Total Parenteral Nutrition (TPN)
  • Chronic administration of intravenous antibiotics (e.g., for osteomyelitis or cystic fibrosis)
  • Frequent blood component transfusions in patients with chronic anemia or bleeding disorders
  • Difficult peripheral venous access in patients requiring frequent blood sampling or infusions
  • Administration of vesicant or highly irritating medications that cannot be given via peripheral veins

Procedure Steps

  1. Identify the appropriate venous access site (e.g., right internal jugular vein) using ultrasound.
  2. Administer local anesthesia and/or systemic sedation to the patient.
  3. Perform a percutaneous puncture of the target vein under ultrasound guidance.
  4. Insert a guidewire into the vein and confirm its position using fluoroscopy.
  5. Create a subcutaneous pocket in the infraclavicular region or other suitable site for the reservoir.
  6. Create a subcutaneous tunnel from the venous entry site to the reservoir pocket.
  7. Pass the catheter through the tunnel and pull it through to the pocket site.
  8. Dilate the venous entry site and place a peel-away sheath over the guidewire.
  9. Advance the catheter through the sheath until the tip reaches the cavoatrial junction, confirmed by fluoroscopy.
  10. Measure and trim the catheter at the reservoir end to ensure proper fit.
  11. Connect the catheter to the subcutaneous reservoir and secure it with a locking sleeve.
  12. Place the reservoir into the subcutaneous pocket and secure it to the underlying fascia with non-resorbable sutures.
  13. Aspirate and flush the port to ensure patency and functionality.
  14. Close the skin incisions (the pocket and the tunnel entry site) using layered sutures or surgical adhesive.

Coding Guidelines

  • Code 36561 is specific to patients aged 5 years and older; for patients younger than 5 years, use 36560.
  • Imaging guidance, such as ultrasound (76937) and fluoroscopy (77001), is not included in the primary procedure and should be reported separately when documented.
  • Do not report 36561 in conjunction with 36563 (which involves a pump rather than a reservoir).
  • The 'tunneling' aspect is a requirement for this code; if the catheter is not tunneled, a different CVAD code must be used.
  • If the procedure is performed as a replacement of an existing port through the same venous access, use 36582 instead of 36561.
  • Documentation must clearly state that both a tunnel was created and a reservoir was implanted.
  • For the removal of a tunneled CVAD with a reservoir, use code 36589.
