Ask Dr. Z

We have neuro IR doctors who are treating pseudotumor cerebri by placing a stent in the venous sinus. The question is regarding coding the venous and IVUS portion of the exam. We would appreciate your input. For cerebral venous imaging: RT/LT jugular, RT/LT sigmoid sinuses, RT/LT transverse sinuses (from a femoral access): 36012 x 2, 75860 x 2 for jugular veins. When the catheter is advanced, is additional cath/imaging billable for the sigmoid or transverse sinuses? Is there a different access code when a transtorcular approach is used? (Ex. LT IJV via right-side transtorcular approach) IVUS: RT/LT jugular, RT/LT sigmoid, transverse/sigmoid junction, RT/LT transverse sinuses 37252, 37253? Code additional 37253?
