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

What 76801 covers

This code describes a complete ultrasound assessment of a pregnancy before 14 weeks for a single fetus or the first fetus in a multiple gestation. It is commonly performed in an obstetric office, radiology department, or maternal-fetal medicine setting to assess early pregnancy, such as dating or viability concerns. The examination may document the gestational sac, embryo, cardiac activity, fetal measurements, and relevant maternal structures. An obstetrician, radiologist, or maternal-fetal medicine specialist may interpret the images.

Select this code for a complete early obstetric study, rather than a limited check or a focused follow-up examination. The report should support the gestational age, number of fetuses, images and findings assessed, and the clinical reason for the study. For additional fetuses, report the applicable additional-fetus code with the primary study. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and reporting without a modifier represents the global service.
