Need help. Patient has 70% stenosis of Left Circumflex and 70% stenosis of 1st OM and 100% chronic total occlusion of Lateral 1st OM. Intervention was 1. stenting of Left Circumflex, 2. Atherectomy/Stenting 1st OM and 3. Atherectomy/Stenting of Lateral 1st OM. I was looking at C9600 and C9607 but was told it was incorrect? Any help would be appreciated.
