Billing code 76811: Obstetric ultrasoundMedicare rate & RVUs

Medicare pays $182.03 for 76811 nationally in the office. Local office rates run $163.82–$238.65.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 76811 covers

This transabdominal ultrasound provides a detailed survey of fetal anatomy along with maternal and fetal evaluation. It is commonly performed in the mid-trimester when a structural anomaly is suspected, a prior pregnancy involved a fetal anomaly, or screening findings support a comprehensive anatomic assessment. Obstetric sonographers acquire and document the images; an obstetrician, maternal-fetal medicine specialist, or radiologist interprets the study and reports the findings.

Select this code for a detailed anatomic examination of one gestation, rather than a routine complete survey, a limited study, or a follow-up scan. The report should document the examination performed, image findings, and clinical reason for the detailed assessment. CMS recognizes professional and technical components: append modifier 26 for interpretation only, modifier TC for equipment and staff only, or bill without either modifier for the global service when both components are furnished. For multiple gestations, 76812 describes the detailed examination of an additional fetus.
