Wiki Help!! Need opinion

[HLALJR]

Coding a surgery case - the doctor documents the diagnosis as aortoiliac occlusive disease. I believe the correct code to use should be I74.09, but I have another coder in my office that thinks it would be better to code is as atherosclerosis of aorta and iliac arteries.

I could really use some other opinions on this.
Thanks

I agree with your coding. The alphabetic index for Disease -> arterial -> occlusive directs to code from 'occlusion, by site'. Atherosclerosis would not be correct unless the physician has documented this specifically.
