Noninvasive vascular study
About 93880: Complete bilateral extracranial arterial duplex study
Complete bilateral duplex ultrasound of the neck’s carotid and vertebral arteries, reported when evaluating TIA symptoms, a carotid bruit, or known stenosis.
Complete extracranial duplex uses grayscale imaging, color Doppler, and spectral Doppler to assess the carotid and vertebral arteries on both sides of the neck. A vascular sonographer obtains images and flow velocities in a vascular lab, outpatient imaging center, or office; a radiologist, vascular surgeon, cardiologist, or other qualified physician interprets the examination. The study can evaluate a transient ischemic attack, amaurosis fugax, a carotid bruit, known stenosis, or a treated carotid artery.
Report 93880 for a complete bilateral examination; report 93882 for a unilateral or limited extracranial examination. The report should support the extent examined with bilateral vessel findings, velocity measurements, vertebral flow direction, and plaque or stenosis findings when present. Modifier 26 identifies interpretation alone, modifier TC identifies equipment and staff, and an unmodified claim represents the global service. Because 93880 is priced bilaterally, modifier 50 does not increase payment. When eligible cardiovascular diagnostic studies are performed for the same patient on the same day, the multiple-procedure reduction affects the technical component of the lower-priced service, not its interpretation.
CMS billing rules for 93880
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.
- Multiple procedures
- Cardiovascular diagnostic multiple procedure reduction applies to the technical component.
- Bilateral procedures
- The code is already priced as bilateral; modifier 50 does not increase payment.

93880 billing questions
When should 93882 be reported instead of 93880?
Use 93882 when only one side is scanned or the extracranial examination is limited, such as a focused check of one treated carotid artery. Report 93880 for a complete bilateral evaluation.
Should modifier 50 be added to 93880?
No. The code already describes a bilateral study and is priced that way; modifier 50 does not increase payment.
How does a hospital-based physician bill the interpretation?
The interpreting physician reports 93880 with modifier 26 when the facility supplies the equipment and staff. The facility bills for its technical services separately.
Can a carotid duplex and an echocardiogram on the same day both be billed?
Both may be reported when each is performed and medically necessary, as in some stroke evaluations. If both are eligible for the cardiovascular diagnostic multiple-procedure reduction, it affects the lower-priced technical service.
Is a transcranial Doppler study included in 93880?
No. Code 93880 evaluates extracranial neck vessels. A separately performed and documented intracranial study may be reported with 93886 or 93888, according to its extent.
What documentation supports a complete bilateral study?
Document the carotid and vertebral arteries examined on both sides, Doppler velocities and flow findings, and plaque or stenosis when present. The record should also support the clinical reason for the examination, such as TIA symptoms, a bruit, or known stenosis.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
