How these totals are calculated
  • The total is the sum of the General Payments records CMS published for the labeled program year(s), exactly as published. Nothing is estimated, weighted, or combined across categories.
  • General Payments only. Research and Ownership/Investment are separate datasets and are never summed with these figures; amounts are kept separate per program year.
  • Featured-page threshold (a presentation gate, not a judgment): records>=3 OR total>=100 (all years).
  • Methodology & Data — sourcing, labeling, and limitations.
