CPT® Code 36460

The CPT® Code 36460 refers to the procedure of intrauterine fetal transfusion, which is a critical intervention performed during pregnancy. This procedure is primarily indicated when there is a risk to the fetus due to conditions such as Rh incompatibility, where the mother's immune system attacks the fetal red blood cells, particularly in cases involving an Rh-positive fetus. Another significant indication for this transfusion is neonatal alloimmune thrombocytopenia (NAIT), a condition that arises when maternal antibodies target specific antigens on the fetal platelets, leading to a decrease in platelet count and potential complications for the fetus. Prior to conducting the transfusion, a thorough abdominal ultrasound is performed to assess the fetal position, locate the placenta, and identify the umbilical vein, as well as to evaluate the levels of amniotic fluid. This imaging is crucial for ensuring the safety and accuracy of the procedure. Continuous ultrasound monitoring is employed to guide the placement of the needle into the umbilical vein at the site of placental insertion, although in some cases, the needle may be inserted directly into the fetal abdomen. The transfusion itself involves administering blood to the fetus, and both the mother and fetus are closely monitored throughout the procedure and during the recovery period to ensure their well-being and to manage any potential complications that may arise.
