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(2 entities) | 4 | $455 |
| CSL Behring | 2 | $238 |
| Portola Pharmaceuticals, LLC | 1 | $124 |
| Eisai Inc. | 1 | $124 |
| Melinta Therapeutics, LLC | 1 | $123 |
| Lilly USA, LLC | 1 | $120 |
| Amgen | 1 | $105 |
| Johnson & Johnson | 2 | $48 |
| Astellas Pharma US Inc | 1 | $17 |
| Inari Medical, Inc. | 1 | $16 |
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
$1,372 in reported general payments places this provider in the 90th percentile of 3,289 emergency medicine providers in Florida.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
