What 93931 covers

This service uses ultrasound imaging and Doppler assessment to evaluate blood flow in upper extremity arteries or an arterial bypass graft. It may help investigate arm or hand ischemia, diminished pulses, or suspected arterial narrowing or blockage. A vascular sonographer typically acquires the images and waveforms in a vascular laboratory or imaging department, and a qualified practitioner interprets the study.

Report 93931 for a unilateral examination or a limited study; a complete bilateral examination is represented by 93930. Documentation should identify the side and extent examined, the clinical reason, and the findings supporting the interpretation. The service may be billed globally when one entity provides both portions, or split with modifier 26 for the professional interpretation and modifier TC for the technical service, including equipment and staff. When multiple cardiovascular diagnostic procedures are performed, the multiple procedure reduction applies to the technical component.

How to choose

93930Arm arterial duplex
93930 is for a complete bilateral upper extremity arterial duplex. Choose 93931 for a unilateral examination or a limited study.
93922Arterial study
93922 reports limited physiologic arterial testing at two levels, rather than duplex imaging of upper extremity arteries or a bypass graft.
93923Arterial physiology
93923 reports physiologic arterial testing at three or more levels. Use 93931 when the service is an upper extremity arterial duplex.

93931 billing questions

When should 93930 be reported instead?

Use 93930 for a complete bilateral upper extremity arterial duplex examination. Use 93931 for a unilateral examination or a limited study.

What do modifiers 26 and TC represent?

Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.

Does the multiple procedure reduction affect both components?

The cardiovascular diagnostic multiple procedure reduction applies to the technical component of this service.

How should the report support 93931?

Document the clinical indication, side and arterial territory examined, relevant images or Doppler findings, and the interpretation. The record should make clear why the study was unilateral or limited.

How does 93931 differ from 93922 or 93923?

93931 describes duplex imaging and Doppler evaluation of upper extremity arteries or a bypass graft. Codes 93922 and 93923 describe physiologic arterial testing organized by the number of levels assessed.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
