    Default Subclavian Stenosis

    AAPC: Back to School
    should this be coded as 433.80 or 440.29? i always thought of the subclavian as extremity but was told subclavian stenosis is imaged with the carotid duplex and should be 433.80????
    any thoughts on this?

    I think that 4471 is the correct code.

    Default Stenosis of subclavian vein

    Subclavian is a vein...not an artery. Refer to anatomy chart of circulatory
    system. Subclavian is located in the upper thorax, not in an extremity.
    Code: 459.2

    There is a subclavian artery and vein. IE: If you are doing perpherial vascular and your catheter ends up in the Lt subclavin artery you code 36215 which is: Selective catheter placement, arterial system; each first order thoracic or brachiocephalic branch, within a vascular family.

    Your documentaion should also lead you to the correct diag but you can use 447.1. There is also a dx 435.2 Subclavian Steal Syndrome, which is an occulsion of the subclavian artery per ICD-9.

    Hope this helps clarify this some.

    I think that a subclavian vein stenosis is asymptomatic.
