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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
