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 |
|---|---|---|
| Merck | 350 | $652,599 |
| Pfizer | 61 | $352,255 |
| Astrazeneca UK Limited | 15 | $45,770 |
| Amgen | 8 | $17,705 |
| Eli Lilly | 1 | $8,380 |
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
$1,076,709 in reported general payments places this provider in the 95th percentile of 1,665 diagnostic radiology providers in Pennsylvania.
