CPT code 93925: Arterial duplex, complete bilateral study2026 Medicare rate & RVUs

Medicare pays $237.48 for 93925 nationally in the office. Local office rates run $206.41–$330.47.

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

What 93925 covers

This noninvasive ultrasound examines arteries in both legs, including arterial bypass grafts when assessed. Duplex imaging combines vessel images with Doppler information about blood flow, helping evaluate findings such as narrowing, blockage, or graft-flow concerns. Vascular sonographers commonly perform the acquisition in a vascular laboratory, hospital outpatient department, or imaging practice; a qualified physician interprets the study and documents the findings.

Report 93925 for a complete bilateral arterial duplex, rather than a limited study. Documentation should identify the bilateral examination, the arteries or grafts assessed, and the interpreted findings. The code is priced as bilateral, so modifier 50 does not increase payment. The global service is billed without a component modifier; modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. The cardiovascular diagnostic multiple procedure reduction applies to the technical component.
