The Smartdop^® XT is Koven’s most advanced vascular testing system. With 14 inflation ports, a simple one-button start, and dual side cuff inflation, the Smartdop^® XT can perform rapid bilateral, multiple level vascular studies. Integrated pulse volume and Doppler, PPG (photoplethysmography) & temperature probes enable a wide variety of arterial and venous studies for the evaluation and management of vascular disease.

Features & Capabilities

• Comprehensive vascular testing system with both Doppler and automatic testing capabilities
• Wide variety of arterial and venous testing capabilities
• 14 inflation ports and dual-sided cuff inflation for rapid bilateral multiple level arterial studies
• Built-in pulse volume capabilities
• Smart-XT-Link software creates easy to read test reports and PDF & DICOM^® compatible files that can be integrated into your facility's EHR or PACS system
• Modality Worklist software available for seamless file transfers (provided separately)

Code 93922

Limited bilateral noninvasive physiologic studies of upper or lower extremity arteries, (eg, for lower extremity: ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus bidirectional, Doppler waveform recording and analysis at 1-2 levels, or ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus volume plethysmography at 1-2 levels, or ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries with, transcutaneous oxygen tension measurement at 1-2 levels)

(When only 1 arm or leg is available for study, report 93922 with modifier 52 for a unilateral study when recording 1-2 levels. Report 93922 when recording 3 or more levels or performing provocative functional maneuvers)

(Report 93922 only once in the upper extremity(s) and/or once in the lower extremity(s). When both the upper and lower extremities are evaluated in the same setting, 93922 may be reported twice by adding modifier 59 to the second procedure)

(For transcutaneous oxyhemoglobin measurement in a lower extremity wound by near infrared spectroscopy, use 0493T)

Code 93923

Complete bilateral noninvasive physiologic studies of upper or lower extremity arteries, 3 or more levels (eg, for lower extremity: ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus segmental blood pressure measurements with bidirectional Doppler waveform recording and analysis, at 3 or more levels, or ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus segmental volume plethysmography at 3 or more levels, or ankle/brachial indices at distal posterior tibial and anterior tibial/dorsalis pedis arteries plus segmental transcutaneous oxygen tension measurements at 3 or more levels), or single level study with provocative functional maneuvers (eg, measurements with postural provocative tests, or measurements with reactive hyperemia)

(When only 1 arm or leg is available for study, report 93922 for a unilateral study when recording 3 or more levels or when performing provocative functional maneuvers)

(Report 93923 only once in the upper extremity(s) and/or once in the lower extremity(s). When both the upper and lower extremities are evaluated in the same setting, 93923 may be reported twice by adding modifier 59 to the second procedure)

(For transcutaneous visible light hyperspectral imaging measurement of oxyhemoglobin, deoxyhemoglobin, and tissue oxygenation, use 0631T)

Code 93924

Noninvasive physiologic studies of lower extremity arteries, at rest and following treadmill stress testing, (ie, bidirectional Doppler waveform or volume plethysmography recording and analysis at rest with ankle/brachial indices immediately after and at timed intervals following performance of a standardized protocol on a motorized treadmill plus recording of time of onset of claudication or other symptoms, maximal walking time, and time to recovery) complete bilateral study.

(Do not report 93924 in conjunction with 93922, 93923)
