Just wanted to make sure I'm doing this one right. It's the one about the coronary artery bypass graft with cardiopulmonary bypass.
For the diagnoses, I have coded 414.01 for the arteriosclerotic heart disease, 411.1 for the angina, 496 for the COPD and 415.11 for the postoperative pulmonary embolus. But I'm not as worried about those as the procedure codes...
I have 36.13 for the (aorto)coronary bypass of three coronary arteries (an open 3-vessel CABG), 39.61 for the cardiopulmonary bypass, and 36.15 for the single internal mammary-coronary artery bypass. I'm pretty confident about the first two codes but I'm not sure if I should code separately the code for the mammary artery. I know that I don't need to code the harvesting of the saphenous vein because that is bundled into the CABG in the ICD-9, but I also know I need 3 procedure codes. They don't describe the extra required treatment of the postoperative pulmonary embolus so I know it's not that.
Just hoping I'm on the right track. This cardiovascular stuff is so complicated!
Thanks!
