What 93925 covers
This noninvasive ultrasound examines arteries in both legs, including arterial bypass grafts when assessed. Duplex imaging combines vessel images with Doppler information about blood flow, helping evaluate findings such as narrowing, blockage, or graft-flow concerns. Vascular sonographers commonly perform the acquisition in a vascular laboratory, hospital outpatient department, or imaging practice; a qualified physician interprets the study and documents the findings.
Report 93925 for a complete bilateral arterial duplex, rather than a limited study. Documentation should identify the bilateral examination, the arteries or grafts assessed, and the interpreted findings. The code is priced as bilateral, so modifier 50 does not increase payment. The global service is billed without a component modifier; modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. The cardiovascular diagnostic multiple procedure reduction applies to the technical component.

- 93926 is for a limited lower extremity arterial duplex. Use 93925 when the documented examination is complete and bilateral.
- 93922Arterial studyOne or two levels
- 93922 reports physiologic arterial testing at two levels, not duplex imaging of arteries or bypass grafts.
- 93924Exercise arterial studyBilateral, rest and treadmill
- 93924 is an exercise-based physiologic vascular study. Choose 93925 when the service performed is a complete bilateral arterial duplex.
- 93970Venous duplex scanComplete bilateral extremity study
- 93970 is a complete bilateral venous duplex study. 93925 examines lower extremity arteries or arterial bypass grafts.
93925 billing questions
When should 93925 be chosen over 93926?
Use 93925 for a complete bilateral lower extremity arterial duplex. Code 93926 describes a limited study, so the documented extent of the examination determines the choice.
Should modifier 50 be added for both legs?
No. 93925 is already priced as a bilateral service, and modifier 50 does not increase payment.
How are the professional and technical services billed?
Bill without a component modifier when reporting the global service. Use modifier 26 for the professional interpretation or modifier TC for the technical service when those components are billed separately.
Does the multiple procedure reduction affect both components?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component of 93925.
What documentation supports a complete bilateral study?
Document that the examination covers both lower extremities, identify the arteries or bypass grafts assessed, and retain the study findings and physician interpretation.
Is 93925 a physiologic pressure study?
No. It reports duplex imaging of lower extremity arteries or arterial bypass grafts. Codes such as 93922 and 93923 describe physiologic arterial testing at specified levels.
Where these rates come from
