Coverage Criteria for Peripheral Venous Examinations

by  Find-A-Code
April 9th, 2018

According to National Government Services LCD L33627, indications for venous examinations are separated into three major categories: deep vein thrombosis (DVT), chronic venous insufficiency, and vein mapping. Studies are medically necessary only if the patient is a candidate for anticoagulation, thrombolysis or invasive therapeutic procedure(s).

Since the signs and symptoms of arterial occlusive disease and venous disease are so divergent, the performance of simultaneous arterial and venous studies during the same encounter should be accompanied by a clear assessment of the clinical need for both studiesConsequently, documentation clearly supporting the medical necessity of both procedures performed during the same encounter must be available in the patient’s medical record. 

Deep Vein Thrombosis (DVT)

The signs and/or symptoms of DVT are relatively non-specific; and due to the risk associated with pulmonary embolism (PE), objective testing is allowed in patients who are candidates for anticoagulation or invasive therapeutic procedures for the following:

These studies are rarely considered medically necessary for the following:

Chronic Venous Insufficiency

Chronic venous insufficiency may be divided into three categories: primary varicose veins, recurrent DVT, and post-thrombotic (post-phlebitic) syndrome. Peripheral venous studies may be indicated for the evaluation of:

Vein Mapping

Mapping the saphenous veins prior to scheduled revascularization procedures is covered by Medicare when it is expected that an autologous vein will be used to help select an optimal native vessel for grafting .

Vein mapping is not always necessary as a routine pre-operative study, and clinical indications should be noted on the request.  

Vein mapping may be performed prior to creating a dialysis fistula. Please see “VI. Vessel Mapping of Vessels for Hemodialysis Access (93970, 93971G0365).”
