Noninvasive vascular study
About 93970: Bilateral complete extremity venous duplex scan
Complete bilateral extremity venous duplex evaluates both arms or both legs for suspected thrombosis or venous insufficiency using imaging, compression, and flow assessment.
A vascular technologist or sonographer uses grayscale imaging and Doppler to assess veins in both arms or both legs, including responses to compression and flow maneuvers. The examination may investigate leg swelling or suspected deep vein thrombosis; reflux testing may help evaluate chronic venous insufficiency before vein treatment. The record should identify the venous segments examined and findings on each side. The study is commonly performed in vascular laboratories, radiology departments, hospitals, or vein clinics and interpreted by a radiologist, vascular surgeon, or other qualified physician.
Report one unit for a complete bilateral study of an extremity pair, supported by images and an interpretation addressing both sides. Use 93971 for a single extremity or a limited examination. Modifier 26 identifies the interpretation alone, and modifier TC identifies the equipment and staff portion; billing without either modifier represents the global service. The code is already priced for both sides, so modifier 50 does not increase payment. When multiple eligible cardiovascular diagnostic tests are billed together, CMS applies its multiple procedure reduction to the technical component.

93970 billing questions
When should 93971 be reported instead of 93970?
Use 93971 for a unilateral extremity venous study or a limited examination. Use 93970 when both arms or both legs receive a complete venous study.
Should modifier 50 be added when both legs are scanned?
No. The code is already priced as bilateral, so modifier 50 does not increase payment.
Does scanning both legs require two units?
No. One complete bilateral study of the legs is one unit of 93970, not one unit per leg.
How is the service split between a hospital and the reading physician?
The physician who interprets the study in a facility reports 93970 with modifier 26, while the facility bills for the technical service. An office providing both portions reports the global service without either component modifier.
Is an arterial duplex on the same day separately reportable?
A separately indicated and documented bilateral lower extremity arterial duplex may be reported with 93925. When eligible cardiovascular diagnostic tests are billed together, the CMS multiple procedure reduction applies to the technical component.
What documentation supports the complete bilateral study?
The record should include images, the venous segments examined on both sides, compression and flow findings, and a signed interpretation addressing each side. Include reflux findings when reflux is assessed.
