Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $2,833 of the $3,585 with a category attached, or 79.0%. It is spread thinly across 15 manufacturers, the largest accounting for just 22.6% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $1,245 and has fallen 87.2% since, to $159 in 2025.
Across 48 payments — averaging $74.70 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| E.r. Squibb & Sons, L.L.C. | 10 | $809 |
| Blue Earth Diagnostics | 2 | $699 |
| Johnson & Johnson | 16 | $688 |
| Seagen Inc. | 5 | $367 |
| Jazz Pharmaceuticals Inc. | 3 | $252 |
| Bayer | 3 | $152 |
| Genentech USA, Inc. | 1 | $97 |
| Merck | 1 | $94 |
| Amgen | 1 | $93 |

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
$3,585 in reported general payments places this provider in the 80th percentile of 339 radiation oncology providers in Pennsylvania.
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 | 29 | $554 |
| Lidocaine Hcl ViscousLidocaine Hcl | 11 | $150 |
| Anastrozole | 12 | $92 |
