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.

How to choose
- 76801Obstetric ultrasound
- 76801 is a first-trimester transabdominal obstetric examination. Choose 76817 for the transvaginal examination; both can be appropriate when both approaches are performed and documented.
- 76830Pelvic ultrasound
- 76830 describes transvaginal pelvic ultrasound outside an obstetric examination. Use 76817 when the study evaluates a pregnancy.
- 76815Obstetric ultrasound
- 76815 is selected for a limited obstetric ultrasound. 76817 identifies an obstetric examination performed transvaginally, not simply a limited study.
- 76816Obstetric ultrasound
- 76816 describes follow-up obstetric ultrasound assessment per fetus. 76817 is distinguished by its transvaginal approach, not by follow-up status.
76817 billing questions
How is 76817 different from 76801?
76817 identifies an obstetric examination performed transvaginally. 76801 is a first-trimester transabdominal obstetric examination; both may be reported when both approaches are performed and documented.
Can 76817 be reported with a transabdominal obstetric ultrasound?
Yes, when the transabdominal and transvaginal examinations are both medically indicated, actually performed, and separately supported by the record. Document the approach and findings for each.
Which modifiers identify the components?
Use modifier 26 for the professional interpretation and modifier TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
When should 76830 be used instead?
76830 is for a transvaginal pelvic ultrasound in a non-obstetric context. Use 76817 when the transvaginal examination is an obstetric study of a pregnancy.
What documentation supports 76817?
The record should identify the pregnancy-related reason for the examination, the transvaginal approach, and the findings in the interpretation. Retain the study images and report.
