Ask Dr. Z

History documents prior ruptured abdominal aortic aneurysm repair in 2001. Now with a left common iliac artery pseudoaneurysm. Do you agree that although the current encounter report documents that after internal iliac artery embolization, two overlapping iliac limb prostheses were deployed within the prior left iliac limb and extended to the native external iliac artery; code 34707 instead of 34710 should be used since the current encounter is for treatment of a different aneurysm 20 years later although in the previously placed bifurcated device for the prior ruptured AAA repair?
