CPT 93931: Upper Extremity Arterial Duplex Scan, Unilateral

Medicare pays $84 on average nationally for this procedure.

CPT code 93931 describes a duplex ultrasound scan of the upper extremity arteries or bypass grafts performed on one side to evaluate arterial blood flow and detect stenosis or occlusion; this noninvasive vascular diagnostic service is typically provided in an outpatient vascular lab, radiology department, or hospital-based imaging center and is categorized as a noninvasive arterial diagnostic procedure for the upper limb.

Clinical & Coding Specifications

Clinical Context

A typical patient is a 68-year-old with a history of peripheral arterial disease and symptoms of unilateral upper extremity ischemia, such as rest pain, coolness, pallor, decreased radial pulse, or nonhealing hand ulcers. The patient is referred from vascular surgery or primary care for a noninvasive arterial duplex evaluation of the right upper extremity arteries to assess arterial patency, flow velocity, stenosis, or anastomotic integrity of a prior bypass graft.

Workflow: The vascular laboratory schedules the patient for a dedicated arterial duplex of one upper extremity. On arrival, vascular technologists verify identity and indications, review prior imaging and procedures, and obtain vital signs including blood pressure and limb comparison when indicated. The technologist performs segmental duplex imaging from the subclavian/axillary through the radial and ulnar arteries using B-mode, color Doppler, and spectral Doppler to measure peak systolic velocities, waveform morphology, and velocity ratios. Images and velocity measurements are documented in the study report. A vascular medicine or vascular surgery provider interprets the study and issues a signed report describing hemodynamic significance of any stenosis or occlusion and recommendations for further management. Typical sites of service include an outpatient vascular laboratory, hospital outpatient department, or inpatient bedside when urgent evaluation is required.

Typical modifiers used to bill this service reflect laterality, professional vs technical components, unusual procedural circumstances, same-day multiple procedures, or interruptions in service; the most common payer interactions involve Medicare and commercial payors such as Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and employer/union plans (BUCA).
