CPT code 93923: Arterial physiology, three or more levels2026 Medicare rate & RVUs in Texas
Reports a complete bilateral, multilevel physiologic assessment of upper or lower extremity arterial circulation when three or more levels are evaluated.
Medicare pays $122.96–$140.01 for 93923 in the office in Texas, from Beaumont, TX to Austin, TX. Which amount applies depends on the service address.
Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93923 covers
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.

How to choose
- 93922Arterial studyOne or two levels
- Choose 93923 when the documented physiologic evaluation covers three or more levels. Choose 93922 for one or two levels.
- 93924Exercise arterial studyBilateral, rest and treadmill
- 93924 is the lower-extremity exercise study. 93923 is selected for a physiologic study covering three or more levels, without using exercise as the defining service.
- 93925Arterial duplexComplete bilateral study
- 93925 evaluates lower-extremity arteries with duplex imaging. 93923 evaluates arterial physiology through measures such as pressures, plethysmography, or Doppler waveforms.
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.
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 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.
