Summary and payment records

  • CMS publication 2026-06-30
Read the payment records

“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.
  • Methodology & Data — sourcing, labeling, and limitations.

Provider summaries generated . CMS updates this data on an annual cycle, and corrections or successful disputes made at CMS may not yet appear here. The official CMS record is authoritative for the current state. View the official CMS record ↗
