A real-time transabdominal obstetrical ultrasound, designated by CPT® Code 76810, is a diagnostic imaging procedure performed on a pregnant uterus to evaluate both fetal and maternal health after the first trimester, specifically when the gestation period is equal to or greater than 14 weeks 0 days. This ultrasound is crucial for assessing the viability of the fetus, determining the presence of multiple gestations, and measuring fetal age through specific fetal measurements. Additionally, it allows for the evaluation of the fetus's position, the location of the placenta, and a comprehensive survey of fetal anatomy, which includes examining the intracranial structures, spinal column, abdominal organs, and the heart with a four-chamber view. The procedure also involves identifying the umbilical cord insertion site and assessing the volume of amniotic fluid, as well as evaluating the maternal uterus and adnexa when visible. To conduct the ultrasound, the mother is typically required to present with a full bladder, which enhances the clarity of the images obtained. During the procedure, acoustic coupling gel is applied to the skin of the lower abdomen, and a transducer is used to emit ultrasonic wave pulses. These waves are directed at the fetus and surrounding structures, and the echoes produced are recorded to create images. Any abnormalities detected during the examination are thoroughly evaluated. Following the procedure, the physician reviews the ultrasound images and provides a written interpretation, ensuring that all findings are documented for further assessment. It is important to note that CPT® Code 76805 is utilized for a single gestation or the first gestation in a multiple pregnancy after the first trimester, while CPT® Code 76810 is specifically designated for each additional gestation.
