CPT® Code 36510

1. Indications

The catheterization of the umbilical vein, as described by CPT® Code 36510, is indicated for several specific clinical scenarios in newborns. These indications include:

• Diagnostic Purposes The procedure may be performed to obtain blood samples for laboratory analysis, which can help in diagnosing various conditions affecting the newborn.
• Therapeutic Interventions Catheterization allows for the administration of medications, fluids, or blood products directly into the newborn's circulatory system, which is critical in managing certain medical conditions.
• Monitoring The procedure facilitates continuous monitoring of the newborn's hemodynamic status, which is essential in critically ill infants.

2. Procedure

The catheterization of the umbilical vein involves several detailed procedural steps, which are as follows:

• Step 1: Preparation The umbilical cord stump and the surrounding area are thoroughly cleansed with a bactericidal solution to reduce the risk of infection before any surgical intervention is performed.
• Step 2: Securing the Stump The stump of the umbilical cord is tied at the base using a purse-string suture or umbilical tape. This step is crucial for controlling any bleeding that may occur during the procedure.
• Step 3: Cutting the Cord The cord is cut horizontally, which allows for the identification of the umbilical vein and the two arteries that accompany it. This step is essential for accessing the correct vessel for catheterization.
• Step 4: Clearing the Vein Any thrombi present in the umbilical vein are cleared to ensure unobstructed blood flow. This is a critical step to prepare the vein for catheter insertion.
• Step 5: Dilation of the Vein The umbilical vein is then dilated to facilitate the insertion of the catheter. This step ensures that the catheter can be placed without causing damage to the vessel.
• Step 6: Catheter Selection and Preparation An appropriately sized catheter is selected based on the newborn's size and clinical needs. The catheter is flushed with heparin solution to prevent clotting and is then closed with a stopcock to maintain sterility.
• Step 7: Catheter Insertion The catheter is carefully inserted through the umbilical vein and advanced until good blood return is obtained, indicating that the catheter is correctly positioned within the vascular system.
• Step 8: Securing the Catheter The catheter is secured in place using the previously placed purse-string suture or umbilical tape, ensuring that it remains stable and in the correct position.
• Step 9: Verification of Positioning Finally, the correct positioning of the catheter is verified through radiographs, which are reported separately. This step is essential to confirm that the catheter is in the appropriate location for effective use.

3. Post-Procedure

After the catheterization procedure is completed, several post-procedure care steps and considerations are important. The catheter site should be monitored for any signs of infection, bleeding, or complications. Regular assessments of the catheter's patency and the newborn's hemodynamic status are essential to ensure that the catheter is functioning correctly. Additionally, healthcare providers should be vigilant for any adverse reactions to medications administered through the catheter. The newborn's overall condition should be closely monitored, and any necessary follow-up imaging or interventions should be planned based on the clinical situation. Proper documentation of the procedure and any findings is also critical for ongoing care and compliance with medical standards.
