What 93926 covers
A vascular sonographer obtains duplex images and flow information from arteries in one lower extremity, or performs a limited examination of the lower extremity arteries or an arterial bypass graft. A vascular specialist or other qualified interpreting physician reviews the study and documents findings. Common clinical reasons include evaluation of suspected peripheral arterial disease, claudication, or concern for stenosis, and surveillance of an arterial bypass graft. Studies are performed in settings such as an outpatient vascular laboratory or hospital imaging department.
Select this code when the documented examination is unilateral or limited; use the bilateral study code when a complete examination of both lower extremities is performed. The report should identify the side and vessels examined, the clinical indication, relevant flow or waveform findings, and the interpretation. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and reporting without either modifier represents the global service. When multiple cardiovascular diagnostic procedures are performed, the multiple procedure reduction applies to this code’s technical component.

93926 billing questions
When should 93926 be used instead of 93925?
Use 93926 for a unilateral or limited lower extremity arterial duplex. Use 93925 for a complete bilateral lower extremity arterial duplex.
How does this differ from 93922 or 93923?
93926 describes duplex imaging and flow assessment of lower extremity arteries or a bypass graft. Codes 93922 and 93923 describe physiologic arterial testing at specified levels rather than this duplex examination.
Can the interpretation and technical service be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
Which portion is subject to the cardiovascular multiple procedure reduction?
The reduction applies to the technical component of 93926 when multiple cardiovascular diagnostic procedures are performed. It does not describe a reduction to the professional interpretation.
What documentation supports reporting a limited study?
Document the clinical reason for the examination, the side and vessels evaluated, the scope of the study, the findings, and the interpreting physician’s conclusion.
