Ask Dr. Z

Patient admitted with an acute myocardial infarction. Procedure note documents that a stent was placed in the diagonal vessel of the left main which was presumed to be the culprit vasculature. They then redirected the wire down the left anterior descending artery and in the proximal left anterior descending artery, stented an eccentric lesion that was 85% stenosed. The wire was redirected down the circumflex system and a stent was deployed across the circumflex marginal vessel. The physician is billing 92941, 92938 and 92944. I don't agree with this code selection.
