Ask Dr. Z

I need advice with the following case please. "Intra-op direct exposure of superior opthalmic vein with angiocath access was secured. Patient then brought to IR department for embolization of carotid-cavernous fistula. In IR, angiocath sticking out of opthalmic vein accessed with microcath and moved to cavernous sinus with coil placement. After embolization, patient went back to operating room for decannulation and ligation of opthalmic vein."  Would you do anything for the catheterization into cavernous sinus from superior opthalmic (36211)? Unlisted (36299)? Or just stick with embolization codes and follow-up angio from RCCA? There is no mention of imaging findings through opthalmic vein, just advancement of microcath and coil embolization into cavernous sinus.
