Vascular diagnostic testing

About 93979: Limited abdominal vascular duplex study

Reports a focused duplex ultrasound assessment of abdominal aortic, caval, iliac, or related bypass-graft vasculature rather than a complete study.

This code represents a limited duplex ultrasound assessment of the aorta, inferior vena cava, iliac vessels, or a related bypass graft. The exam uses ultrasound imaging and Doppler flow analysis to evaluate the specified vascular area. Vascular laboratories, radiology departments, and physician offices may perform the study for a focused clinical question, such as follow-up of a known abdominal vascular abnormality or assessment of a graft. The documented anatomy and scope distinguish a limited study from a complete examination.

Report the code when the performed study is limited in scope; the record should identify the vessel or graft examined, the clinical indication, and the findings supporting the evaluation. CMS recognizes professional and technical components: report modifier 26 for interpretation only, modifier TC for equipment and staff, or no component modifier for the global service. The cardiovascular diagnostic multiple procedure reduction applies to the technical component when applicable. The global service includes both components.

93979 billing questions

How does this differ from 93978?

93979 represents a limited examination of the relevant abdominal vessels or graft, while 93978 is the complete-study sibling. Use the code that matches the documented scope of the examination.

Can the professional and technical portions 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.

When does the multiple procedure reduction affect this code?

CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component. It does not apply to the professional component under the rule provided for this code.

How is this different from 93975 or 93976?

Those codes describe duplex evaluation of visceral organ vascular flow. Choose 93979 for a limited assessment of the aorta, IVC, iliac vasculature, or a related bypass graft.

What should the report document?

Document the clinical reason for the study, the specific vessel or graft examined, the limited scope of the evaluation, and the duplex findings.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
