CPT Code 93925 | Duplex Scan Of Lower Extremity Arteries Or Bypass Grafts

CPT code 93925 refers to a duplex scan procedure that uses sound waves to create images of the arteries in the lower extremities or arterial bypass grafts.

What Is CPT Code 93925?

CPT 93925 is a medical billing code that refers to a procedure called a duplex scan of the lower extremity arteries or arterial bypass grafts.

This procedure involves using a transducer to produce sound waves transmitted through the skin to create an image of the arteries in the lower extremities or bypass grafts.

During the procedure, the patient lies on an exam table. At the same time, the provider applies a gel to the lower extremities to improve the contact between the transducer and the skin and to help the sound waves penetrate more effectively.

The provider then presses the transducer firmly against the skin and moves it back and forth over the examined area. The entire test typically takes about 30 minutes to complete.

Description

The CPT book describes CPT code 93925 as: “Duplex scan of lower extremity arteries or arterial bypass grafts; complete bilateral study.”

Procedure

With the patient lying on an exam table, the provider applies a gel to the lower extremities to improve contact between the transducer and the skin and help the sound waves penetrate the skin better.

The provider then presses the transducer firmly against the skin and sweeps it back and forth over the area to be examined. The test usually takes about 30 minutes.

How To Use CPT 93925

Report 93926 for the same procedure performed on only one lower extremity.

This category of tests includes plethysmography, transcutaneous oxygen tension measurements (TCOM), and Doppler waveform analysis. No need to add modifier 50 for a bilateral study, as that is already mentioned in the description. This procedure includes the use of a simple hand–held device.

CPT includes a range of codes for arterial Doppler studies on the extremities. Coding will vary depending on whether the diagnostic test was a limited or complete study if the study followed a treadmill stress test, and if the study included the criteria for a Duplex scan.

For some providers, coding may also depend on the diagnosis code. Check your provider’s documentation and review the options in code family CPT 93922 to CPT 93931, Non-invasive extremity arterial studies, including digits, to ensure you choose correctly.

Suppose the provider performs a duplex scan of the aorta and iliac arteries as well as the arteries of the lower extremities. In that case, you should be able to report both CPT 93978, which covers a duplex scan of the aorta, inferior vena cava, iliac vasculature, or bypass grafts, and CPT 93925, assuming documentation supports both studies.

CPT 93925 describes the evaluation of the arteries from the groin downward. CPT code 93978 evaluates the arteries from the diaphragm to the groin.

These evaluations, which focus on different body segments, do not overlap, are complementary to each other, and, in combination, provide the provider with the information necessary to develop a treatment plan for the peripheral arterial disease of the legs.

The medical literature indicates that the combination of the two services described by codes CPT 93925 and CPT 93978, in many cases, can be considered the standard of care for the peripheral arterial disease of the legs.
