CTO Definition

Date: Jan 28, 2019

Question:

I am having a disagreement with another coder about whether this is a true CTO or not. Physician documents that the "LAD demonstrates diffuse 80% disease from the ostium to the proximal mid vessel. It is totally occluded around a stent site in the proximal mid vessel." Then he continues to refer to the lesion as a CTO. Is this a true CTO?
