Ask Dr. Z

Just wondering what are your thoughts now on venous manometry done during cerebral angiogram. I checked previous FAQs, but the response was from way back. Case background: "Patient has history of papiledema and vision loss concerning for IIH vs. cerebral venous stenosis. Via right CFA, bilateral ICA catheterized angiogram was done, right CFV was accessed, and cath was advanced to left jugular bulb then to left sigmoid sinus, the torcula, and up the superior sagital sinus at the level of vertex. Venous manometry was then performed." I got the ICA code, for the venous I got 36012. For venous manometry do I use unlisted code or do not code it at all?
