Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (50.1%), travel and lodging and grants — rather than concentrated in one kind of arrangement. Procept Biorobotics Corporation accounts for 78.7% of it on its own, with 6 other manufacturers making up the rest. 2025 is the largest year on record at $3,970, more than ten times the $59 reported in 2019.
Across 64 payments — averaging $115.55 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Medtronic$598

What the payments were for
- Grants$2583%
- Travel & lodging$3,43646%
- Food & beverage$3,70250%
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 |
|---|---|---|
| Procept Biorobotics Corporation | 38 | $5,817 |
| Medtronic(2 entities) | 12 | $598 |
| Boston Scientific | 8 | $552 |
| Intuitive Surgical | 3 | $151 |
| Endo Pharmaceuticals Inc. | 1 | $150 |
| Teleflex LLC | 1 | $111 |
| Valencia Technologies Corporation | 1 | $16 |
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.
- AquaBeam Robotic System$4,876
- GENERAL ERECTILE DYSFUNCTION$258
- INTERSTIM$240
- XIAFLEX$150
- AQUABEAM SYSTEM$149
- UroLift$111
How this compares
$7,395 in reported general payments places this provider in the 80th percentile of 153 urology 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.
