Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (58.9%), consulting fees and food and beverage — rather than concentrated in one kind of arrangement. Bayer accounts for 62.5% of it on its own, with 22 other manufacturers making up the rest. Reporting peaked in 2021 at $21,675 and has fallen 97.6% since, to $531 in 2025. Among radiation oncology clinicians in FL with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 162 payments — averaging $404.09 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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
$65,462 in reported general payments places this provider in the 95th 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 |
|---|---|---|
| Tamsulosin Hcl | 163 | $1,670 |
| Methylprednisolone | 12 | $77 |
