CPT® Code 76805

Ultrasound, pregnant uterus, real time with image documentation, fetal and maternal evaluation, after first trimester (> or = 14 weeks 0 days), transabdominal approach; single or first gestation

A real-time transabdominal obstetrical ultrasound, designated by CPT® Code 76805, is a diagnostic imaging procedure performed on a pregnant uterus to evaluate both fetal and maternal health after the first trimester, specifically at or beyond 14 weeks of gestation. This ultrasound technique utilizes high-frequency sound waves to create images of the fetus and the surrounding structures within the mother's pelvis. The procedure is essential for assessing various aspects of fetal development and maternal well-being. It helps establish the viability of the fetus, identifies the presence of multiple gestations, and determines fetal age through precise measurements. Additionally, the ultrasound evaluates the position of the fetus and placenta, surveys fetal anatomy—including critical structures such as the brain, spine, abdomen, and heart—and assesses the umbilical cord insertion site and amniotic fluid volume. The procedure requires the mother to have a full bladder, which aids in obtaining clearer images. During the ultrasound, acoustic coupling gel is applied to the lower abdomen, and a transducer is used to capture images by directing ultrasonic waves at the fetus and surrounding structures. The echoes from these waves are recorded to create detailed images, which are then reviewed by the physician for any abnormalities. A written interpretation of the findings is provided, ensuring comprehensive documentation of the procedure. CPT® Code 76805 is specifically utilized for a single gestation or the first gestation in cases of multiple pregnancies after the first trimester, while CPT® Code 76810 is designated for each additional gestation.
