Ask Dr. Z

How would we code this? As a delayed extension even though it’s a main body graft that is being placed? "The patient had an endovascular repair of the abdominal aortic aneurysm in 2013. The aneurysm has started to increase in size due to the main body of the graft having disassociated from the proximal fixation prosthesis. Procedure performed: Graft disassociation producing significant enlargement of the aneurysm sac. This was treated using placement and realigning of the previously placed graft with an endovascular bifurcated tent graft and bridging prosthesis from Endologix. The main body proximal prosthesis and bridging graft were deployed and post dilated with a Reliant balloon. Following placement of the endograft within the previously placed endograft, imaging was performed showing no evidence for type 1, type 2, type 3, or type 4 endoleak."
