CPT® Code 76814

Add-On Code

Ultrasound, pregnant uterus, real time with image documentation, first trimester fetal nuchal translucency measurement, transabdominal or transvaginal approach; each additional gestation (List separately in addition to code for primary procedure)

The CPT® Code 76814 refers to a specific ultrasound procedure performed on a pregnant uterus during the first trimester. This procedure involves real-time imaging with documentation, focusing on the measurement of fetal nuchal translucency. The ultrasound can be conducted using either a transabdominal or transvaginal approach, depending on the clinical situation and the preference of the healthcare provider. Real-time ultrasound technology allows for the visualization of both static images and dynamic movement, providing a comprehensive view of the fetus and surrounding structures. Nuchal translucency is defined as the measurement of subcutaneous fluid accumulation in the neck region of the fetus, which is assessed through ultrasound. The measurement is taken from the maximum thickness of the sonolucent area located between the inner surface of the fetal skin and the outer surface of the soft tissue that covers the cervical spine or occipital bone. An increased measurement of nuchal translucency during the first trimester can indicate potential chromosomal abnormalities and genetic disorders, including but not limited to Down syndrome, trisomy 13 or 18, congenital heart defects, and skeletal dysplasias. It is important to note that CPT® Code 76814 is used specifically for each additional gestation beyond the first, which is coded separately as CPT® Code 76813.
