I'm not sure what code is appropriate for this hemi arch repair for aneurysm. Here are the pertinent details.
Pt. is status post repair of a type A aortic dissection, some time ago. Pt. had a residual type B aortic dissection with aneurysmal arch, the dissection only went to the proximal aorta. Pt. has been followed with CT's and now show progression of the size of the aneurysmal component. Left thoracotomy was performed. Obvious aneurysmal dilatation of the distal aortic arch was noted. Aortic arch was visible from the left chest as was the innominate artery, left subclavian and left common carotid. The arch is opened. A Hemashield graft with a 10mm chimney is chosen and sutured into the aortic arch. A teflon felt buttress was utiilized for the cephalad portion of this repair. The aorta was opened distally to an area that was consistent with the end of the dissection at the proximal descending aorta. The graft was then fashioned and sutured to the aorta distally in this location.
It is the bottom of the arch - hemi arch, that is where the aneurysm is and dissection extends to the proximal descending aorta. I am looking at code 33870, but he does not have to remove the vessels at the top of the arch, all the work is at the bottom. No valve work is done. Just not sure if 33870 is correct or should I use 33875 as the dissection is just to the descending aorta. Or should it be 33870 with a 52 modifier. I have actually coded in the past 33870 exactly as described in the CDR, but this one is different. Any help would be greatly appreciated.
