- How many surgeons perform Leadless Pacemaker Insertion in Missouri?
- 14 Missouri providers billed Medicare for Leadless Pacemaker Insertion (CPT 33274) in CY2024. CMS suppresses providers with 10 or fewer Medicare patients, so the true count is somewhat higher.
- Where does this data come from?
- CMS Medicare Physician & Other Practitioners (fee-for-service Part B claims, CY2024, released May 2026) and CMS Open Payments. Both are official U.S. federal datasets.
- Does this include all of a surgeon's cases?
- No — it covers traditional Medicare only (no Medicare Advantage, commercial, or Medicaid claims). Absolute volumes undercount total practice, but the ranking of high- vs low-volume surgeons is a strong targeting signal.
