Billing code 76810: Obstetric ultrasoundMedicare rate & RVUs

Medicare pays $88.51 for 76810 nationally in the office. Local office rates run $79.86–$115.17.

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

What 76810 covers

This add-on covers the standard obstetric ultrasound evaluation of an additional fetus at 14 weeks or later. It is used in multiple gestations when the primary study evaluates one fetus and the examination also requires evaluation of another. A sonographer typically acquires the images in an office or hospital imaging department; a physician interprets the study and documents the findings. The additional-fetus evaluation is distinct from a detailed fetal anatomic examination.

Report 76810 with the qualifying primary obstetric ultrasound, not as a stand-alone service. Documentation should identify the gestational age and number of fetuses and support the evaluation of each additional fetus. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff, and no component modifier represents the global service. CMS treats this add-on payment within the primary procedure’s global period.
