Tools

• open_payments_company ~172 tokens
  Search payments reported by a manufacturer or GPO in one CMS Open Payments program year. Company matching is a case-insensitive substring and may combine similarly named legal entities.
• open_payments_company_history ~179 tokens
  Build a cross-year CMS Open Payments history for a company-name substring. Annual counts are authoritative for that query; dollar figures cover only the returned bounded sample and company aliases may split or combine legal entities.
• open_payments_compare_companies ~196 tokens
  Compare 2–5 company-name queries across CMS Open Payments program years using authoritative match counts and clearly labeled bounded samples. This does not compare complete spend unless every matching row fits in the sample.
• open_payments_nature_breakdown ~174 tokens
  Break down the bounded payment sample for one recipient, company, or product across years by reported nature of payment. Counts and dollars in the breakdown are sample statistics; annual total_matches remains the authoritative query count.
• open_payments_physician ~255 tokens
  Find CMS Open Payments records for a physician/non-physician practitioner by exact NPI in one program year. Returns the authoritative total match count plus a bounded payment sample; reported relationships do not imply misconduct. If you have a name rather than an NPI, resolve it first against the N
• open_payments_product ~160 tokens
  Search general-payment records associated with a named drug, biologic, device, or medical supply across all five CMS product slots. Product association is reporting-entity supplied and does not prove the payment was exclusively for that product.
• open_payments_product_history ~157 tokens
  Build a cross-year general-payment history for a reported product-name substring across CMS product slots. Product association is reporter-supplied; sample dollar amounts are not complete annual totals.
• open_payments_recipient_history ~182 tokens
  Build a cross-year CMS Open Payments history for an exact recipient NPI. Returns authoritative annual match counts plus bounded samples; sampled dollar totals are explicitly not full-dataset totals.
• open_payments_research ~192 tokens
  Search CMS research-payment records by company, recipient NPI, study name, or state for one program year. Amounts may represent funding routed through an institution and should not automatically be attributed as personal compensation.
• open_payments_search ~637 tokens
  THE source for pharma/device industry money to doctors — "payments from manufacturers to physicians", "which drug companies paid this doctor", "Sunshine Act data", "industry payments to hospitals". Search one CMS Open Payments program-year dataset using structured recipient, company, product, geogra
• open_payments_top_companies ~318 tokens
  Rank the drug and device manufacturers that paid US physicians and teaching hospitals the most in a program year — the "who spends the most on doctors" question. Returns each company with its total US dollars, payment count and how many distinct recipients it reached, ordered by spend. CMS publishes
