CPT Code 93880 | Duplex Scan Of Extracranial Arteries

CPT code 93880 can be used for a non-invasive, painless procedure with ultrasound to create detailed images of the extracranial blood vessels in the head and neck.

What Is CPT Code 93880?

CPT code 93880 describes a procedure called a “Duplex scan of extracranial arteries.”

The purpose of CPT 93880 is to use ultrasound technology to create detailed images of the blood vessels that are located outside of the skull (extracranial) and supply blood to the head and neck.

The term “complete bilateral study” means the procedure will examine both sides of the head and neck. This is done using a handheld device called a transducer that emits high-frequency sound waves into the body. These waves then bounce off the blood vessels and return to the transducer as echoes.

The computer then analyzes the echoes, creating detailed images of the blood vessels that can help identify any blockages or other issues. This procedure is non-invasive and typically painless. 


The CPT book describes CPT code 93880 as: “Duplex scan of extracranial arteries; complete bilateral study.”


During a duplex scanning procedure, a physician or technician uses a handheld probe to emit short ultrasonic pulses that travel into the body.

These pulses are reflected off soft tissue, producing echoes received by the probe. The probe can detect small changes in frequency and can be used to calculate the speed and direction of blood flow.

The scanner can construct an image of a targeted plane within the body by emitting successive pulses and analyzing the resulting echoes.

During the 93880 procedure, the physician examines the vascular flow of both sides of the head and neck.

How To Use CPT 93880

Do not use CPT code 93880 with CPT code 93895.

The National Correct Coding Initiative edits do not prevent reporting carotid Doppler (C{T 93880) on the same day as venous Doppler (CPT 93970 and CPT 93971).

It is not common for both of these exams to be ordered for the same patient on the same service date, and payers may question the medical necessity.

CPT code 93880, “Duplex scan of extracranial arteries,” is indicated for non-invasive physiologic cerebrovascular studies, such as in cases of neck trauma, stroke, and pulsatile tinnitus. It may also be appropriate for patients with systemic atherosclerosis before coronary artery bypass grafting or after carotid surgery.

CPT 93970 and CPT 93971, “Duplex scan of extremity veins,” can be used for peripheral venous exams and are appropriate for conditions such as deep vein thrombosis, chronic venous insufficiency, and vein selection for arterial surgery.

Studies that are deemed medically necessary to determine subsequent treatment are covered.

Make sure to check with the referring physician to identify why the patient needs both exams to ensure the medical necessity.
