Billing code 93930: Arm arterial duplexMedicare rate & RVUs in Washington
Bilateral upper-extremity arterial duplex ultrasound evaluates arm arterial flow when symptoms or findings raise concern for stenosis, occlusion, aneurysm, or graft dysfunction.

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.

How to choose
- 93931Arterial duplex
- 93931 is for a unilateral or limited upper-extremity arterial duplex examination; 93930 covers a complete bilateral examination.
- 93922Arterial study
- 93922 reports physiologic arterial testing at two levels. It is not the bilateral arm arterial duplex imaging reported with 93930.
- 93985Dialysis access mapping
- 93985 is used for complete bilateral duplex vessel mapping for hemodialysis-access planning; 93930 evaluates upper-extremity arteries for diagnostic purposes.
93930 billing questions
When should 93930 be used instead of 93931?
Use 93930 for a complete examination of both arms. Use 93931 when the examination is unilateral or limited.
Should modifier 50 be added?
No. 93930 is already priced as a bilateral service, and modifier 50 does not increase payment.
How are the professional and technical portions billed?
Bill without a component modifier for the global service. Use modifier 26 for the physician’s interpretation or modifier TC for the technical work when those portions are billed separately.
Does the multiple-procedure reduction affect both components?
CMS applies the cardiovascular diagnostic multiple-procedure reduction to the technical component.
What documentation supports a complete bilateral study?
Document the reason for testing, that both arms were examined, the vessels evaluated, the Doppler and imaging findings, and the interpreting physician’s assessment.
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. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
