Payments from drug & device makers
What this record shows

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| AstraZeneca | 12 | $1,599 |
| Eli Lilly | 21 | $1,455 |
| Novartis | 5 | $528 |
| Sanofi | 1 | $83 |
What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
How this compares
$3,665 in reported general payments places this provider in the 90th percentile of 2,212 internal medicine providers in Arizona.
