Question: What is he talking about? New York Subscriber Answer: A repeat is a follow-up exam, and you should report that with 76816 (Ultrasound, pregnant uterus, real time with image documentation, follow-up [e.g., re-evaluation of fetal size by measuring standard growth parameters and amniotic fluid volume, re-evaluation of organ system(s) suspected or confirmed to be abnormal on a previous scan], transabdominal approach, per fetus). The diagnosis is the same as the first one the ob-gyn did. This might be to complete a scan for a malformation (V28.3, Screening for malformation using ultrasonics) or to complete a fetal anatomic survey (V28.81, Encounter for fetal anatomic survey) when he initially did not find any problem.
