CPT Code 93922 | Non-Invasive Evaluation Of Upper Or Lower Extremity Arteries

CPT code 93922 describes a series of non-invasive tests evaluating the circulatory capacity and blood flow of the upper or lower extremity arteries.

What Is CPT Code 93922?

CPT 93922 describes a series of non-invasive tests that evaluate the circulatory capacity and blood flow of the arteries in the upper or lower extremities.

These tests may include ankle/brachial indices, Doppler waveform recording and analysis, volume plethysmography, and transcutaneous oxygen tension measurement.

The tests are performed by attaching devices to the arms, legs, or other body areas and may involve the patient breathing oxygen through a mask to increase oxygen levels around a wound or ulcer.

The tests identify the peripheral vascular disease (PVD) and take approximately 45 minutes to complete. All of the procedures are non-invasive.

Description

The CPT book describes CPT code 93922 as: “Limited bilateral non-invasive physiologic studies of upper or lower extremity arteries, (e.g., 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).”

Procedure

The patient lies on an examination table for transcutaneous oxygen tension measurement. One electrode is placed on the “control site” of the body, usually on the upper chest. Then, two more electrodes are placed just around the wound site.

Sometimes the physician instructs the patient to breathe oxygen through a mask to increase the body’s oxygen level around the wound/ulcer.

This test is used to identify if any peripheral vascular disease (PVD) is present. This entire procedure usually takes around 45 minutes to complete.

In plethysmography, devices are attached to the arms, legs, etc., to find out the circulatory capacity and blood flow of the extremity vessels and to identify any blockage. The medium of procedure can be air, water, etc. All the procedures are non–invasive.

How To Use CPT 93922

No need to add modifier 50 for a bilateral study as the descriptor of CPT 93922 describes a bilateral study.

The use of a simple handheld device is included in CPT code 93922.

When performing a limited bilateral non-invasive physiologic study of the upper or lower extremities, CPT code 93922 should be used to report 1-2 levels of recording when only one arm or leg is available for study, and modifier 52 should be added to indicate a unilateral study.

If three or more levels are recorded, or provocative functional maneuvers are performed, CPT code 93922 should be used without the modifier.

The 93922 CPT code should be reported only once for the upper or lower extremities and if the upper and lower extremities are evaluated in the same setting.

CPT 93922 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 CPT code 0631T.
