What 92933 covers
An interventional cardiologist uses a catheter-based technique to remove or modify obstructive coronary plaque and place an intracoronary stent in one major coronary artery or branch. A typical setting is a cardiac catheterization laboratory, where a calcified coronary lesion may be treated with atherectomy before stenting. Balloon angioplasty performed as part of that intervention is included in this service.
Report 92933 for the atherectomy-and-stent intervention in one major artery or branch; report 92934 for a qualifying additional branch. The procedure report should identify the treated artery or branch and document both atherectomy and stent placement. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
