Coding for percutaneous transluminal revascularization of acute total/subtotal occlusion during acute myocardial infarction

Q.

CPT^® code 92941 is for the treatment of a total or subtotal occlusion occurring during an acute myocardial infarction. Is there a definition of what qualifies as a “subtotal” occlusion? 

A.

Subtotal occlusion is anything less than a total occlusion; in other words, less than a complete occlusion. To report CPT code 92941, what matters is not how occluded the artery is but that the occlusion is causing the acute myocardial infarction. The code and full description are as follows:

92941 Percutaneous transluminal revascularization of acute total/subtotal occlusion during acute myocardial infarction, coronary artery or coronary artery bypass graft, any combination of intracoronary stent, atherectomy and angioplasty, including aspiration thrombectomy when performed, single vessel
