Ask Dr. Z

I need your guidance please. Patient has a type 2 endoleak and is coming in for angiography and possible glue embolization. This is the condensed portion of the report: "The right CFA was accessed with a micropuncture system. This was exchanged for a stiff Glidewire, short 5 French sheath, and pigtail catheter. Aortogram with mesenteric run-off was done. The IMA entering the sac was identified. A 0.18 Glidewire and Renegade catheter were used to traverse the tortuous arc of Riolan and access the IMA and the sac. Glue was diluted 1:3 with oil, and 3 cc of this was used to embolize the sac and distal IMA." I am reporting code 37242 for the embolization, but I'm unsure about the catheter placement. The physician indicated that this was a third order. Since the SMA and IMA are two separate families, should I be reporting codes 36247 and 36245-59?
