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.

76805 billing questions
When should 76805 be used instead of 76801?
Use 76805 for a standard obstetric ultrasound at 14 weeks or later. Code 76801 is for the corresponding standard examination before 14 weeks.
How is an additional fetus reported?
Report 76805 for the first fetus and 76810 for each additional fetus evaluated. Documentation should identify the gestation and findings for each fetus.
When is 76811 more appropriate?
Use 76811 when a detailed fetal anatomic examination is performed, rather than the standard evaluation represented by 76805. The examination performed and documented determines the code.
How should the professional and technical work be billed?
Use modifier 26 for the professional interpretation and modifier TC for the technical service. Billing without either modifier represents the global service.
What documentation supports 76805?
The record should support gestational age, the single-fetus evaluation, the reason for the study, and the findings and images from the examination, such as fetal measurements and relevant maternal and fetal observations.
