Using Diagnosis 440.3x vs. 996.74

Date: May 4, 2013

Question:

I'm wondering if you can share when you would use ICD-9 code 440.3x and when you would use ICD-9 code 996.74.  Most of our occluded bypasses, whether vein or synthetic, are due to atherosclerosis; however, the description of code 996.74 mentions stenosis, occlusion, thrombus, etc. Thank you in advance for your help!
