Sorted by the number of coronary angioplasty and stenting procedures billed to Medicare, highest first. This is an ordering of one published figure, not a ranking of quality, skill, or outcomes. CMS suppresses counts of 10 and below to protect patient privacy and publishes the range instead, which is not a count of zero; 11 of these clinicians carry that range.

Understanding CMS Data

These figures are based on coronary angioplasty and stenting procedures billed to Original Medicare and Medicare Advantage as reported by the Centers for Medicare & Medicaid Services (CMS) in their August 2026 data release. The CMS data doesn't include procedures performed for patients who have other health care coverage (e.g., commercially insured, self pay, or VA). Furthermore, CMS sums up specific billing codes covering balloon angioplasty, stent placement, plaque removal, and related catheter treatments of the arteries of the heart to calculate this total. The category is named for the group of procedures it covers, not for what each one involved: a procedure counts whether or not a stent was placed. Billing variation and coding errors could potentially affect CMS's data. Therefore, the coronary angioplasty and stenting volume data reported by CMS may be higher or lower than the actual total coronary angioplasty and stenting procedures performed by a clinician. We share the total coronary angioplasty and stenting figures for the clinicians CMS lists under interventional cardiology, cardiology and its subspecialties, cardiac or thoracic surgery, or internal medicine as CMS publishes them, without alteration.
