A real-time transabdominal obstetrical ultrasound, designated by CPT® Code 76802, is a diagnostic imaging procedure performed during the first trimester of pregnancy, specifically for gestations less than 14 weeks 0 days. This ultrasound is crucial for evaluating both fetal and maternal health, providing essential information about the developing fetus and the pregnant uterus, as well as the surrounding pelvic structures of the mother. The procedure is typically conducted with the mother having a full bladder, which enhances the clarity of the images obtained. During the ultrasound, acoustic coupling gel is applied to the skin of the lower abdomen to facilitate the transmission of ultrasonic waves. A transducer is then used to emit these waves, which are reflected back to create images of the fetus and the maternal structures. The ultrasound allows for the assessment of various factors, including the viability of the embryo or fetus, the presence of multiple gestations, fetal age through measurements of the gestational sac and fetus, the position of the fetus and placenta, and the evaluation of amniotic fluid volume. Additionally, it provides insights into the maternal uterus and adnexa. After the procedure, the physician reviews the captured images and provides a written interpretation, which is essential for ongoing prenatal care. It is important to note that CPT® Code 76801 is utilized for a single gestation or the first gestation in a multiple pregnancy during the first trimester, while CPT® Code 76802 is specifically designated for each additional gestation.
