CPT® 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)

Complete bilateral noninvasive physiologic studies of upper or lower extremity arteries, as described by CPT® Code 93923, are comprehensive evaluations aimed at assessing arterial health and identifying potential vascular diseases. These studies are noninvasive, meaning they do not require any surgical procedures or incisions, making them safer and more comfortable for patients. The procedure typically involves the use of advanced technologies such as Doppler ultrasound, plethysmography, and transcutaneous oxygen tension measurements to gather detailed information about blood flow and arterial function. The studies can be performed at three or more levels of the extremities, which allows for a thorough assessment of the arterial system. The Doppler ultrasound component involves placing a probe on the skin over the artery, which detects and records blood flow signals, providing insights into both forward and reverse blood flow patterns. Plethysmography measures blood volume changes in the extremities, which is crucial for diagnosing conditions like deep vein thrombosis and arterial occlusive disease. Additionally, provocative functional maneuvers may be employed to assess how blood flow responds to specific physical changes or occlusions. The choice of studies and the levels at which they are performed depend on the specific type and extent of arterial disease being evaluated. A physician reviews the results and generates a detailed report, ensuring that the findings are accurately documented for further clinical decision-making.
