What 93924 covers
A vascular laboratory performs this physiologic test to assess arterial blood flow in both legs before and after treadmill exercise. Staff may obtain limb pressure measurements and waveform data; a physician or other qualified professional interprets the findings. It is commonly used when leg discomfort occurs with walking or when resting measurements alone do not explain suspected lower extremity arterial disease. The exercise portion helps evaluate how blood flow changes with exertion.
Report 93924 for the complete bilateral rest-and-exercise protocol, supported by documentation of the indication, testing performed, and interpreted results. The code includes both legs, so modifier 50 does not increase payment. The global service may be billed without a component modifier; modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. When multiple cardiovascular diagnostic procedures are reported, the applicable multiple procedure reduction affects the technical component.

- 93923Arterial physiologyThree or more levels
- 93923 describes a more extensive resting physiologic study. 93924 is distinguished by testing both legs at rest and after treadmill exercise.
- 93925Arterial duplexComplete bilateral study
- 93925 is a bilateral lower extremity arterial duplex examination using ultrasound. 93924 is a physiologic study with a treadmill exercise component.
- 93926Arterial duplexUnilateral or limited
- 93926 is a unilateral or limited lower extremity arterial duplex examination. 93924 is a bilateral physiologic rest-and-exercise study.
93924 billing questions
When should 93924 be selected instead of 93922 or 93923?
Use 93924 when the bilateral physiologic evaluation includes measurements at rest and after treadmill exercise. Codes 93922 and 93923 describe resting studies distinguished by their extent.
Does 93924 include testing of both legs?
Yes. The code is priced as bilateral; modifier 50 does not increase payment.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the professional interpretation and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
Does a multiple procedure reduction affect the entire service?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component. It does not reduce the professional component.
Should the resting portion be reported separately from the exercise study?
Report 93924 for the complete bilateral rest-and-exercise protocol rather than separately reporting a resting study for measurements that are part of that examination.
What documentation supports reporting 93924?
Document the clinical reason for testing, the bilateral rest-and-exercise protocol performed, and the interpreted findings, including the response to exercise.
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.
