“Financial relationships do not necessarily indicate an improper relationship; the data is open to interpretation.”

— Centers for Medicare & Medicaid Services, Open Payments

A reported payment reflects a financial relationship a company disclosed. It does not indicate wrongdoing or a conflict of interest, and it says nothing about the quality of a provider's care.

These records are submitted to CMS and attested to by the reporting companies. CMS publishes them as reported; this site mirrors them without independent verification.

A payment attributed to a provider may have been made to a third party — a hospital, practice, or research institution — rather than paid to the provider personally.

How these totals are calculated
  • This total is the sum of the individual General Payments record amounts CMS published for the labeled program year(s); each record amount is used unmodified. The total itself is computed by this site. 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) AND records>=2 AND NPI identity (all years).
  • Methodology & Data — sourcing, labeling, and limitations.
