What 93971 covers
Extremity venous duplex combines grayscale imaging and Doppler flow assessment with vein compression and other maneuvers to assess venous patency and flow. A painful, swollen leg or arm with suspected deep vein thrombosis is a common reason for the examination; assessment of known thrombosis or venous reflux may also prompt it. Vascular sonographers obtain images in office vascular labs, emergency departments, and hospital imaging departments. A radiologist, vascular surgeon, or other qualified physician interprets the findings.
Report 93971 for a unilateral extremity venous duplex or a limited study, including a focused bilateral examination; a complete bilateral arm or leg venous examination is 93970. Record which limb and veins were examined, compression and Doppler findings, and any technical limits that prevented full evaluation. When components are billed separately, use modifier 26 for physician interpretation and modifier TC for equipment and staff; bill the global service without a component modifier when both are furnished and billed together. For multiple eligible cardiovascular diagnostic tests performed for the same patient on the same date, Medicare's multiple procedure reduction affects the technical component.

93971 billing questions
When should 93970 be reported instead of 93971?
Use 93970 when a complete duplex evaluation of the veins of both arms or both legs is performed and documented. Report a unilateral or limited bilateral examination with 93971.
Can 93971 be used for arterial duplex of a leg?
No. 93971 describes an extremity venous duplex examination. Lower extremity arterial duplex examinations are reported with 93925 or 93926; upper extremity arterial duplex examinations are reported with 93930 or 93931.
How are the technical and interpretation components reported separately?
When billing split components, the provider billing for equipment and staff uses modifier TC, while the interpreting physician uses modifier 26 and documents the interpretation in a signed report. An entity billing for both components reports the global service without a component modifier.
Does a multiple procedure reduction affect this study?
When multiple eligible cardiovascular diagnostic tests are performed for the same patient on the same date, Medicare's cardiovascular diagnostic multiple procedure reduction affects the technical component of eligible services.
What documentation supports a limited study?
The report should identify the extremity and veins examined, document compression and Doppler findings, and state the clinical reason for the exam, such as leg swelling or suspected deep vein thrombosis. Document why any intended segment could not be evaluated.
