Drugs and devices associated with these payments

CMS records which products a payment was associated with, not how the money was allocated. Association is not allocation: one payment can be associated with several products, and a product listing does not mean the payment was made because of that product. Product detail covers 2023-2025.

Research and ownership

$2,314.83 in research payments reported 2019-2025. Research payments are often institution-directed and tied to clinical trials: they are reported under a clinician's name but frequently go to a hospital or research organization, and usually reflect participation in medical research.

These are normal questions. A good clinician will welcome them.
