Sigmoid Sinus Dural AV Fistula Embolization

Date: Aug 20, 2013

Question:

I'm trying to discern between using codes 61624 and 61626. The patient has a sigmoid sinus dural AV fistula, which was embolized in two sessions. The arterial feeder is off the right occipital artery. The venous portion is the sigmoid sinus. Initial treatment/embolization of the fistula was performed solely via the right occipital artery feeder. The follow-up treatment involved embolization of the occipital artery feeder and sigmoid sinus. The fistula connects the extracranial vascular system to the intracranial vascular system, it seems. Would code 61624 be appropriate for both procedures regardless of the site of embolization (occipital artery feeder only vs. occipital artery feeder and sigmoid sinus)?
