Thread: Coronary Artery Modifier

  1. #1

    Default Coronary Artery Modifier

    Does anyone have a diagram or listing of what branches are under the LC, LD and RC modifier? I am having trouble finding something that is easy to understand. I have a patient whose SVG to the mid proximal circumflex and distal circumflex was stented and I do not know which modifier to use.

    LC = left main, circumflex, obtuse marginal 1 and 2

    LD = left anterior descending, diagonal 1 and 2

    RC = right coronary, posterior descending, and pls

    You would use the LC modifier in your instance.

    With the grafts it will depend on the artery that it is serving.
