2025 CPT code 93923
(Active) Effective Date: N/A Revision Date: N/A Non-Invasive 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 upper or lower extremity arteries; 3 or more levels, or single level with provocative maneuvers.
Modifiers 26 (professional component), 51 (multiple procedures), 59 (distinct procedural service), and others may be applicable depending on the circumstances.
Medical necessity is established by the presence of symptoms or risk factors suggesting peripheral artery disease (PAD), such as intermittent claudication, rest pain, ulceration, or gangrene.The test helps to determine the severity and location of the disease to guide treatment decisions (e.g., medical management, surgical intervention, or endovascular procedures).
Physician performs the study, interprets results, and provides copies to the patient's records.This involves using equipment to measure blood pressure and blood flow at various locations in the extremities.The physician analyzes the data to determine if there are any significant obstructions or abnormalities.

In simple words: This test checks blood flow in the arteries of your arms and/or legs.It uses non-invasive methods to measure blood pressure and flow at several points to detect any blockages.
This CPT code encompasses a complete bilateral noninvasive physiologic evaluation of the arterial system in the upper or lower extremities.The procedure involves assessing blood flow at three or more levels (e.g., 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 three or more levels; or, alternatively, with volume plethysmography or transcutaneous oxygen tension measurements at three or more levels).A single-level study may also be reported if provocative functional maneuvers (postural changes, reactive hyperemia, cold stress) are performed.The study assesses blood flow patterns and the potential presence of blockages.
Example 1: A patient presents with intermittent claudication in their left leg.A complete bilateral noninvasive physiologic study of the lower extremity arteries (93923) is performed, revealing significant stenosis in the superficial femoral artery., A patient with a history of diabetes mellitus type 2 and known peripheral vascular disease undergoes a 93923 study to assess the extent of arterial disease in both arms before a planned arteriogram., A young patient experiences cold sensitivity and discoloration in their fingers.A 93923 study of the upper extremities is done with provocative maneuvers (cold stress) to diagnose Raynaud's phenomenon.
Detailed documentation should include the patient's history, physical examination findings, the specific locations of the measurements (at least three levels for a complete study, or one level with provocative maneuvers), the results of the ABI, Doppler waveform analysis, volume plethysmography (if performed), or transcutaneous oxygen measurements,and the physician's interpretation.
** Handheld Doppler devices without hard copy output for bidirectional flow analysis are not separately reportable.The study must use equipment capable of producing a record that allows analysis of bidirectional blood flow, volume plethysmography, or transcutaneous oxygen tension.
