Answer: The correct CPT Codes for this procedure is usually 93971 (Duplex scan of extremity veins including responses to compression and other maneuvers; unilateral or limited study). Payment will depend on whether the diagnosis code supports medical necessity for this service. Among the ICD-9 codes that are most often accepted are:

History of previous harvest or stripping of vein (V45.81, Other postsurgical status; aortocoronary bypass status)

Previous history of thrombophlebitis (e.g., 451.0,Phlebitis and thrombophlebitis; of superficial vessels of lower extremities; or 997.2, Peripheral vascular complications)

Severe varicose veins (e.g., 454.2, Varicose veins of lower extremities; with ulcer and inflammation)
