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 |
|---|---|---|
| Siemens Medical Solutions USA, Inc. | 4 | $309 |
| Organogenesis Inc. | 1 | $30 |
| Jazz Pharmaceuticals Inc. | 1 | $24 |
| AbbVie | 1 | $18 |
How this compares
$380 in reported general payments places this provider in the 30th percentile of 465 radiation oncology 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Gabapentin | 72 | $1,161 |
| Nystatin | 36 | $661 |
| Tamsulosin Hcl | 52 | $612 |
| Oxycodone Hcl | 36 | $595 |
