36558

Insertion of tunneled centrally inserted central venous catheter, without subcutaneous port or pump, adult (18 years or older)

CPT code 36558 describes the surgical placement of a tunneled central venous catheter into a central vein (e.g., subclavian, jugular, femoral) for an adult patient aged 18 years or older. This catheter is designed for long-term intravenous access, meaning it is intended to remain in place for an extended period, typically weeks to months. The 'tunneled' aspect refers to the creation of a subcutaneous tunnel from the venipuncture site, under the skin, to an exit site on the chest wall (or other suitable location), providing a barrier against infection. This code specifically applies when a subcutaneous port or pump is NOT implanted with the catheter, distinguishing it from codes describing placement of implanted ports or pumps.

Clinical Indications

  • Long-term administration of intravenous fluids, medications (e.g., antibiotics, chemotherapy, pain management), or nutritional support (e.g., total parenteral nutrition).
  • Frequent or continuous blood product transfusions.
  • Repeated blood sampling for diagnostic testing when peripheral access is difficult or impractical.
  • Hemodialysis or apheresis access (note: specific codes for hemodialysis catheters may apply, but this code covers initial placement for long-term general access).
  • Administration of vesicant or irritant medications that cannot be given safely via peripheral veins.
  • Patients with poor peripheral venous access due to disease, obesity, or prior treatments.
  • Monitoring central venous pressure (CVP).

Procedure Steps

  1. Patient preparation, including informed consent, antiseptic skin preparation of the insertion site, and draping.
  2. Administration of local anesthesia at the venipuncture and tunnel exit sites.
  3. Accessing a central vein (e.g., internal jugular, subclavian, femoral) using ultrasound guidance or anatomical landmarks, typically via a Seldinger technique.
  4. Advancement of a guidewire through the needle into the central vein.
  5. Dilation of the venipuncture site to accommodate the catheter.
  6. Creation of a subcutaneous tunnel from the venipuncture site to the chosen exit site using a tunneling device.
  7. Threading the catheter through the subcutaneous tunnel and into the central vein, ensuring the tip is appropriately positioned, usually in the lower superior vena cava or cavoatrial junction.
  8. Confirmation of catheter tip position, typically with fluoroscopy or chest X-ray.
  9. Securing the catheter at the exit site with sutures or other fixation devices.
  10. Dressing application and patient education regarding catheter care.
  11. Verification of blood return and flushing of catheter lumens.

Coding Guidelines

  • This code (36558) is for the initial placement of a tunneled central venous catheter in an adult (18 years or older) without a subcutaneous port or pump.
  • Imaging guidance (e.g., ultrasound, fluoroscopy) used for central venous access or catheter tip confirmation is typically included in this code and should not be separately reported unless specific exceptions apply (e.g., diagnostic venography prior to placement, which may be reported with codes such as 36005 or 36010, if medically necessary and separately documented).
  • Repositioning or replacement of a previously placed tunneled central venous catheter may require different codes (e.g., 36581, 36582, 36583, 36584, 36585) depending on the circumstances.
  • Removal of a tunneled central venous catheter is reported with a separate code (e.g., 36589).
  • Do not report 36558 in conjunction with codes for non-tunneled central venous catheter insertion (e.g., 36556, 36557) unless distinct procedures are performed at separate sites.
  • This code includes all necessary components of catheter insertion, including local anesthesia, venipuncture, tunnel creation, and securing the catheter.
  • For patients younger than 18 years, use codes 36557 (for non-tunneled) or other age-appropriate codes for tunneled catheters if they exist.
