CPT® Code 36510

The procedure described by CPT® Code 36510 involves the catheterization of the umbilical vein in newborns for diagnostic or therapeutic purposes. This procedure is typically performed shortly after birth and is crucial for accessing the newborn's circulatory system. The umbilical vein, which carries oxygenated blood from the placenta to the fetus, is identified and accessed through the umbilical cord stump. The process begins with the cleansing of the umbilical cord stump and the surrounding area using a bactericidal solution to minimize the risk of infection. Following this, the stump is secured at the base using a purse-string suture or umbilical tape to control any potential bleeding. The cord is then cut horizontally, allowing for the identification of the umbilical vein and the two accompanying arteries. Thrombi, or blood clots, are cleared from the vein to ensure proper flow, and the vein is dilated to facilitate catheter insertion. An appropriately sized catheter is selected, flushed with heparin solution to prevent clotting, and closed with a stopcock. The catheter is then carefully inserted into the umbilical vein and advanced until a good blood return is obtained, indicating proper placement. Finally, the catheter is secured in place using the previously placed purse-string suture or umbilical tape, and its correct positioning is confirmed through radiographic imaging, which is reported separately. This procedure is essential for various medical interventions, including fluid administration, blood sampling, and monitoring of the newborn's condition.
