CPT code 76817: OB ultrasound, transvaginal approach2026 Medicare rate & RVUs

Medicare pays $92.85 for 76817 nationally in the office. Local office rates run $82.63–$124.29.

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

What 76817 covers

This service uses an endovaginal ultrasound transducer to obtain real-time images of the pregnant uterus and related structures. It is commonly performed in an obstetric or gynecologic office, emergency department, or hospital imaging setting, often when early pregnancy structures are not adequately assessed abdominally or when a closer view is needed. A sonographer may acquire the images, with a qualified practitioner interpreting the study and documenting the findings.

Report 76817 when the documented obstetric examination uses the transvaginal route; the approach and clinical question should be clear in the record and supported by the images and interpretation. It may be reported with a transabdominal obstetric study when both distinct examinations are performed and documented. CMS recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no modifier represents the global service.
