Our Physicians have started using the Intravascular Ultrasound more and the guidelines that I have found still leave me with questions. Sometimes the physician will use IVUS bilaterally and usually includes the Inferior Vena Cava.
For example the Physician will measure the IVC, Right Common Iliac Vein, Right External Iliac Vein, Left Common Iliac Vein, and Left External Iliac Vein.
Since this is being used to measure each vessel should each vessel be reported? I see that a 50 modifier is not allowed and I do not see an MUE limit posted anywhere.
Would the correct coding be:
37252 (IVC)
37253 (RCIV)
37253 (REIV)
37253 (LCIV)
37253 (LEIV)

Any clarification is GREATLY appreciated.
