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 |
|---|---|---|
| GW Research Limited | 6 | $1,657 |
| Acadia Pharmaceuticals Inc | 4 | $353 |
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
$2,010 in reported general payments places this provider in the 65th percentile of 26 epilepsy providers in Missouri.
