If you want to bring it up
Most clinicians are glad to talk about this. A respectful way in:
- "I saw Mark Walker 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.
