Can you please explain to me on coding for balloon angioplasty when you would consider it "open"? My doctors feel when they use catheters and guidewires to do aorta aneurysm repairs and angioplasty procedures that they should be billed with the "open" code and not the "radiologicial procedure" code. AAA they want "00770", and femoral angioplasty they want "01270". What makes a procedure open???
