CPT® Code 76941

Ultrasonic guidance for intrauterine fetal transfusion or cordocentesis, as described by CPT® Code 76941, involves the use of ultrasound technology to assist in specific medical procedures aimed at addressing fetal health concerns. This guidance includes both imaging supervision and interpretation, which are critical for ensuring the safety and accuracy of the procedures being performed. Intrauterine fetal transfusion is a therapeutic intervention indicated for fetuses that are at risk of anemia due to conditions such as Rh incompatibility, where the mother's immune system attacks the fetal red blood cells. Additionally, fetal transfusion may be necessary in cases of neonatal alloimmune thrombocytopenia, where maternal antibodies target fetal platelets, leading to potential complications. Cordocentesis, also known as percutaneous umbilical cord sampling, is another procedure performed under ultrasound guidance. It involves obtaining a blood sample from the fetus via the umbilical cord, which is essential for diagnosing various fetal conditions, including anomalies, infections, thrombocytopenia, anemia, or isoimmunization. Prior to conducting either procedure, an abdominal ultrasound is performed to assess the position of the fetus, locate the placenta, and identify the umbilical vein, as well as to evaluate the level of amniotic fluid. Continuous ultrasound imaging is utilized to ensure the accurate placement of the needle, whether it is inserted into the umbilical vein for cordocentesis or into the fetal abdomen for transfusion. The physician is responsible for providing a comprehensive written report detailing the imaging aspects of the procedure, which is crucial for medical records and further patient management.
