What 76805 covers

This service is a standard transabdominal ultrasound for evaluating a pregnancy with one fetus at 14 weeks or later. A sonographer acquires and documents the images; an obstetrician, radiologist, or other qualified practitioner interprets them. It is commonly used for a second-trimester fetal survey and may assess fetal number and presentation, placental location, amniotic fluid, fetal measurements, and anatomy appropriate to the examination. A targeted, detailed fetal anomaly evaluation is a different service.

Report 76805 for the standard examination when the pregnancy is at least 14 weeks and one fetus is evaluated. The report and retained images should support the gestational age, the single-fetus examination, the clinical reason, and the findings assessed. For a multiple gestation, this code represents the first fetus; 76810 is the add-on for each additional fetus. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment-and-staff service, and no modifier represents the global service.
