Counts and ordering reflect Medicare fee-for-service claims (2024) from the CMS Medicare Physician & Other Practitioners dataset — a 65+ subset, not all care, and not a quality, outcome, or "best" ranking. Absence from this list does not mean a provider does not perform upper endoscopy (EGD). Source: CMS NPPES (June 2026).
