Billing code 93882: Carotid duplexMedicare rate & RVUs

Medicare pays $123.92 for 93882 nationally in the office. Local office rates run $107.83–$170.83.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93882 covers

This ultrasound examines blood flow in extracranial arteries, most often the carotid arteries, using imaging and Doppler techniques. A vascular sonographer or other trained imaging staff member performs the acquisition; a physician or other qualified practitioner interprets the findings. It may be performed in a vascular laboratory, imaging department, or office for evaluation of a carotid bruit, cerebrovascular symptoms, or known carotid disease when the examination is unilateral or otherwise limited.

Select this code from the extent of the study actually performed, not from the severity of a suspected stenosis. The report should identify the side and vessels examined, the reason for any limited scope, the findings, and the interpreting practitioner’s conclusion. The service may be billed globally, or the interpretation may be reported with modifier 26 and the equipment-and-staff portion with modifier TC. When multiple cardiovascular diagnostic procedures are performed, the CMS multiple-procedure reduction applies to the technical component.
