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.
If you want to bring it up
Most clinicians are glad to talk about this. A respectful way in:
- "I saw Hiroki Nariai listed in the CMS Open Payments database. Can you tell me about your work with those companies?"
- "Is there a generic or alternative to this medication, and would it work as well for me?"
- "What made you choose this particular treatment for my situation?"
These are normal questions. A good clinician will welcome them.
