What 93922 covers
This noninvasive physiologic test evaluates arterial blood flow in an upper or lower extremity using pressure measurements and Doppler or plethysmographic waveforms. A common lower-extremity application is resting ankle-brachial index testing. Vascular laboratory staff or other trained personnel typically obtain the measurements in an outpatient office or hospital department; a qualified physician interprets the findings. The service is limited to one or two testing levels, or a single level assessed with a provocative maneuver.
Report the code for the documented limited study, not a more extensive multilevel examination or an exercise study. The record should identify the extremity tested, the measurement levels or maneuver, and the results and interpretation. The code is priced as bilateral, so modifier 50 does not increase payment. It has separately priced professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no component modifier represents the global service. When multiple cardiovascular diagnostic procedures are performed, the multiple-procedure reduction applies to this code’s technical component.

How to choose
- 93923Arterial physiologyThree or more levels
- 93922 is for a limited physiologic assessment at one or two levels, or one level with a provocative maneuver. Choose 93923 when the documented physiologic study is more extensive.
- 93924Exercise arterial studyBilateral, rest and treadmill
- 93924 is the lower-extremity arterial physiologic study associated with exercise testing. A limited resting assessment without exercise testing is reported with 93922 when its level criteria are met.
- 93925Arterial duplexComplete bilateral study
- 93925 uses duplex imaging to assess bilateral lower-extremity arteries. Code 93922 reports a limited physiologic assessment, such as pressure and waveform testing.
- 93930Arm arterial duplexComplete bilateral study
- 93930 assesses bilateral upper-extremity arteries with duplex imaging; 93922 is a limited physiologic arterial study and does not describe that imaging examination.
93922 billing questions
How does this differ from 93923?
Use 93922 for a limited study covering one or two levels, or a single level with a provocative maneuver. Code 93923 describes a more extensive physiologic study.
Does this code include both sides?
Yes. The code is priced as bilateral, and modifier 50 does not increase payment.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 reports the interpretation and modifier TC reports the technical portion. Without either modifier, the claim represents the global service.
What documentation supports the limited study?
Document the extremity, the testing levels or single-level provocative maneuver, the measurements or waveforms, and the interpreting clinician’s findings.
Does a multiple-procedure reduction affect both components?
The cardiovascular diagnostic multiple-procedure reduction applies to the technical component of 93922.
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.
