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 | 4 | $2,442,158 |
| Taiho Oncology, Inc. | 1 | $118 |
| AstraZeneca | 1 | $100 |
| Genentech USA, Inc. | 1 | $36 |
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
Too few clinical pathology/laboratory medicine providers in District of Columbiato place this figure against a meaningful peer group, so we don't.
