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

$77,759.52 in ownership or investment interests, as reported to CMS. These are holdings a clinician or an immediate family member has in a company, not payments received.
