What 76812 covers
This add-on represents a detailed ultrasound assessment of an additional fetus in a multiple gestation. The examination may include evaluation of fetal anatomy and related pregnancy structures, with findings documented separately for each fetus examined. Obstetricians, maternal-fetal medicine specialists, and radiologists commonly perform or interpret these studies in office or hospital imaging settings when a detailed fetal assessment is indicated.
Report 76812 with the primary detailed obstetric ultrasound, 76811, for each additional fetus that receives the detailed assessment. Documentation should identify the fetuses evaluated and support the scope and findings of the examination for each. CMS classifies 76812 as an add-on: it must be billed with a primary procedure and is paid within that procedure’s global period. The diagnostic service has professional and technical components. Report modifier 26 for the interpretation or modifier TC for the equipment and staff; billing without either modifier represents the global service.
