2025 CPT code 93924
(Active) Effective Date: N/A Revision Date: N/A Vascular Diagnostic Studies - Noninvasive extremity arterial studies, including digits Medicine Services and Procedures > Non-Invasive Vascular Diagnostic Studies Feed
Complete bilateral noninvasive physiologic study of lower extremity arteries at rest and following treadmill stress testing.
Modifiers 26 (professional component), 51 (multiple procedures), and others may apply depending on the circumstances.
Medical necessity for 93924 is established based on the patient's clinical presentation (e.g., symptoms of peripheral arterial disease, risk factors for vascular disease), the need to assess the severity and extent of arterial disease, and to guide treatment planning (e.g., medical management, surgical intervention).
The physician is responsible for placing blood pressure cuffs, obtaining Doppler signals, performing ABI measurements, monitoring symptoms and exercise tolerance, and interpreting the results. This includes the selection of appropriate testing methodology and the analysis of collected data.

- 93922-93931 (Noninvasive extremity arterial studies, including digits)
In simple words: This test checks the blood flow in both legs' arteries before and after exercise on a treadmill. It uses special tools to measure blood flow and pressure and records how long it takes to walk, when pain starts, and how long it takes to recover.
This code encompasses a comprehensive bilateral noninvasive physiologic study of the lower extremity arteries.The study involves evaluating arterial blood flow at rest and after standardized treadmill stress testing.Measurements include ankle-brachial indices (ABI) immediately after exercise and at timed intervals during the recovery period.Additional data collected includes time to onset of claudication or other symptoms, maximal walking time, and recovery time.The evaluation incorporates bidirectional Doppler waveform recording and analysis, volume plethysmography, or transcutaneous oxygen tension measurements at three or more levels (high thigh, low thigh, calf, ankle, metatarsal, and toes) or, alternatively, at a single level if provocative functional maneuvers (e.g., postural changes, reactive hyperemia) are performed.
Example 1: A 65-year-old male presents with intermittent claudication in his right leg.A complete bilateral lower extremity arterial study (93924) is performed to assess the severity and location of arterial disease., A 70-year-old female with a history of diabetes mellitus and peripheral vascular disease undergoes a complete bilateral lower extremity arterial study (93924) before and after treadmill stress testing to evaluate her response to exercise and identify potential areas of ischemia., A 50-year-old male with a suspected peripheral artery aneurysm undergoes a complete lower extremity arterial study (93924) with provocative maneuvers to further evaluate the hemodynamic significance of his suspected lesion.
** This code is used for a complete study involving both legs.If only one leg is studied, select the appropriate code from 93922-93923 based on the type of testing done.
