CPT code 93926: Arterial duplex, unilateral or limited2026 Medicare rate & RVUs

Medicare pays $139.95 for 93926 nationally in the office.

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

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.
