Just a brief question on coding for coronary artery vs non coronary artery procedures. Read that any procedures consisting of the coronary artery are to be coded in the medicine section, is this pretty much regarding mainly catheters? While I was practicing coding some scenarios did come across a sample I was coding for CABG which I was using the cardio codes but did notice there were medicine codes for CABG but mentions catheterizing. Wondering is that the keyword to let me know that anything of coronary artery with mention of catheters is to be coded in medicine instead of coding everything that is regarding the coronary artery be coded in medicine?

Thank you much
