Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $1,096 of the $1,225 with a category attached, or 89.5%. It is spread thinly across 13 manufacturers, the largest accounting for just 16.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2024 at $614 and has fallen 68.5% since, to $193 in 2025.
Across 26 payments — averaging $47.11 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Seagen Inc.$207
- AstraZeneca$193
- Sobi, Inc$157
- Pfizer$154
- Johnson & Johnson$140
- Janssen Scientific Affairs, LLC$92
- plus $282 from 7 others
What the payments were for
- Food & beverage$1,09689%
- Education$12911%
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 |
|---|---|---|
| Seagen Inc. | 2 | $207 |
| AstraZeneca | 2 | $193 |
| Sobi, Inc | 2 | $157 |
| Pfizer | 2 | $154 |
| Johnson & Johnson | 6 | $140 |
| Janssen Scientific Affairs, LLC | 1 | $92 |
| Novartis | 3 | $81 |
| Merck | 3 | $65 |
| Lilly USA, LLC | 1 | $47 |
| Regeneron Healthcare Solutions, Inc. | 1 | $39 |
| EMD Serono, Inc. | 1 | $22 |
| Pharmacyclics LLC, An Abbvie Company | 1 | $15 |
| E.r. Squibb & Sons, L.L.C. | 1 | $14 |
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
$1,225 in reported general payments places this provider in the 55th percentile of 92 medical oncology providers in Oregon.
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 |
|---|---|---|
| Letrozole | 19 | $318 |
Paid to pharmacies, not to this prescriber.
