From the government website OpenPaymentsData.CMS.org:
Sometimes, doctors and hospitals have financial relationships with health care manufacturing companies. Open Payments is the federally run transparency program that collects information about these financial relationships and makes it available to you. These relationships can involve money for research activities, gifts, speaking fees, meals, or travel. One of the ways we provide this data to the public is through this search tool, which allows you to search for a doctor, teaching hospital, or company that has made payments. Exploring this information, and discussing the results you find with your healthcare provider, can help you make more informed healthcare decisions.
