What this record shows
This record is dominated by food and beverage: $124 of the $148 with a category attached, or 83.9%. Bayer accounts for 83.9% of it on its own, with 1 other manufacturer making up the rest. That places this record below the midpoint for radiation oncology clinicians in NJ, where the typical reported total is $491.
Across 2 payments — averaging $74.21 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Bayer$124
- Myovant Sciences Inc.$24

- Food & beverage$12484%
- Education$2416%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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 |
|---|---|---|
| Bayer | 1 | $124 |
| Myovant Sciences Inc. | 1 | $24 |
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.
- Nubeqa$124
How this compares
$148 in reported general payments places this provider in the 25th percentile of 132 radiation oncology providers in New Jersey.
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 | 17 | $159 |
Paid to pharmacies, not to this prescriber.
