Total number of coronary angioplasty and stenting procedures this clinician billed to Medicare in the most recent 12-month claims period, as reported by CMS.
CMS reports this as a range rather than an exact number because it suppresses counts of 10 and below. It does not mean zero.
CMS suppresses counts of 10 or fewer to protect patient privacy, so it publishes the range rather than a number and no exact percentile exists. Every clinician in that range sits below those with a count of 11 or more, which places them at or below the 29th percentile. This is not a count of zero, and it is not a measure of the clinician's total practice.

Dr. Zaidi's Coronary Angioplasty and Stenting Billing Volume Compared to Peers
CMS reports this clinician's count as a range rather than an exact number, so no single point can be marked. Every clinician CMS reports as 1-10 sits below every clinician with an exact count above that range, which puts them at or below the 29th percentile: the shaded band. The curve begins at the 30th percentile because CMS suppresses counts below 11, and 2,620 clinicians in the group carry that range instead of a number. It ends at the 99th percentile, and a small number of clinicians bill more than that.

Previous data releases
CMS refreshes this data "on a quarterly basis, as technically feasible." The table shows this clinician's figures from each CMS data release.
| CMS data release | Coronary angioplasty and stenting procedures billed | Percentile rank |
|---|---|---|
| August 11, 2026 Current | 1-10 | 29% or below |
| June 26, 2026 Prior | 1-10 | 30% or below |
About these releases. Each release counts procedures over what CMS describes as "a one-year observation window, with a lookback beginning three months prior to the present day", allowing three months for claims to be submitted and processed. CMS does not publish the start and end dates of the window behind any release, and consecutive releases may cover overlapping periods, or the same period with later-arriving claims added.
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.
National Percentile Calculation
CMS publishes its own percentile for this data using a single, national pool that also includes the clinicians listed with other specialties, such as Nurse Practitioner and Hospitalist. We use CMS's percentile formula, but restrict the comparison group to the clinicians CMS lists under interventional cardiology, cardiology and its subspecialties, cardiac or thoracic surgery, or internal medicine, so our number answers a narrower question: how does this clinician's procedure volume compare with other clinicians who billed Medicare for at least one coronary angioplasty and stenting procedure and reported one of those specialties?
