MLA Documentation in Cath Report

Date: May 6, 2024

Question:

Patient with angina and CAD comes in for left heart cath/coronary angiograms. The physician states in his findings left main eccentric 60% distal with MLA 7.1 mm2 and normal iFR 0.95 in mid LAD. LM MLA was 6-7 mm2. How is MLA (minimum lumen area) calculated? Is this done via IVUS? And if so can we code IVUS, 92978, based off this documentation? We would, of course, also code the heart cath and iFR.
