What CPT code should be used for ultrasound aorta?

The appropriate CPT code for an ultrasound of the aorta is 76700, which specifically refers to a complete ultrasound examination of the abdominal aorta. If the examination is focused on a specific area, such as for an aneurysm or other abnormalities, you might use 76705 for a limited study. Always consult the most recent coding guidelines or the specific context of the examination to ensure accurate coding.
