Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 15 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Polynovo North America LLC accounts for 75.1% of it on its own, with 3 other manufacturers making up the rest. 2025 is the largest year on record at $149, more than ten times the $11 reported in 2020. That places this record below the midpoint for surgery clinicians in OR, where the typical reported total is $1,338.
Across 15 payments — averaging $28.73 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Polynovo North America LLC$324
- Integra Lifesciences Corporation$77
- Solventum Corporation$19
- Zimmer Biomet$11
Across 2 payments — averaging $9300.00 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Mallinckrodt Hospital Products Inc.$19K
What the payments were for
- Food & beverage$431100%
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 |
|---|---|---|
| Polynovo North America LLC | 12 | $324 |
| Integra Lifesciences Corporation | 1 | $77 |
| Solventum Corporation | 1 | $19 |
| Zimmer Biomet | 1 | $11 |
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.
- Novosorb BTM$149
How this compares
$431 in reported general payments places this provider in the 35th percentile of 386 surgery 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 |
|---|---|---|
| Oxycodone Hcl | 15 | $89 |
Paid to pharmacies, not to this prescriber.
