About 93923: Multilevel extremity arterial physiology study
Reports a complete bilateral, multilevel physiologic assessment of upper or lower extremity arterial circulation when three or more levels are evaluated.
This noninvasive study evaluates arterial perfusion in an upper or lower extremity at three or more levels. Depending on the clinical question, the vascular laboratory may combine segmental pressures, ankle-brachial indices, volume plethysmography, or continuous-wave Doppler waveform analysis. It is commonly ordered for suspected peripheral arterial disease, including claudication, rest pain, or a nonhealing lower-extremity wound. Vascular technologists typically acquire the measurements in an office vascular lab or outpatient facility; a qualified practitioner interprets the findings.
Choose the code based on the documented extent of the physiologic examination, not simply the number of limbs. The record should identify the extremity or extremities studied, the levels assessed, the measurements or waveforms obtained, and the interpretation. The study is priced as bilateral, so modifier 50 does not increase payment. It may be billed globally or split into modifier 26 for interpretation and modifier TC for equipment and staff. When multiple cardiovascular diagnostic procedures are reported, the multiple-procedure reduction applies to the technical component.
CMS billing rules for 93923
- 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.

93923 billing questions
How does this differ from 93922?
93923 is for a physiologic study evaluating three or more levels; 93922 is the lower-level study for one or two levels. The documented extent of testing determines the choice.
Should modifier 50 be added for testing both sides?
No. The code is already priced as bilateral, and modifier 50 does not increase payment.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the interpretation or modifier TC for the equipment and staff portion. Without either modifier, the claim represents the global service.
Does the cardiovascular multiple-procedure reduction affect both portions?
The CMS multiple-procedure reduction applies to the technical component. It does not apply to the professional component under the rule supplied for this code.
When is 93924 a better fit?
Use 93924 for a lower-extremity arterial study that evaluates circulation with exercise. Use 93923 when the documented physiologic assessment covers three or more levels.
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.
