Billing code 93930: Arm arterial duplexMedicare rate & RVUs

Medicare pays $198.74 for 93930 nationally in the office. Local office rates run $173.24–$274.90.

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

What 93930 covers

This study uses ultrasound imaging and Doppler measurements to assess arterial flow in both arms. Vascular sonographers typically acquire the images in an outpatient vascular laboratory or hospital, and a qualified physician interprets the findings. It may be ordered for suspected upper-extremity arterial narrowing or blockage, an aneurysm, or assessment of an arterial bypass graft. The report should identify the clinical indication, the vessels examined, relevant flow findings, and the physician’s interpretation.

Report 93930 for a complete bilateral arterial duplex examination; it represents both arms, not a separate unit for each side. Use 93931 for a unilateral or limited examination. The global service includes the professional interpretation and the technical work; modifier 26 identifies the interpretation, and modifier TC identifies equipment and staff. CMS applies the cardiovascular diagnostic multiple-procedure reduction to the technical component. Because 93930 is priced as bilateral, modifier 50 does not increase payment.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor.
