Payments from drug & device makers
What this record shows
This record is dominated by education: $1,200 of the $1,693 with a category attached, or 70.9%. Great Lakes Orthopedics accounts for 70.9% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2022 at $1,414 and has fallen 85.1% since, to $210 in 2025. That places this record below the midpoint for orthopaedic surgery clinicians in WI, where the typical reported total is $2,708.
Across 9 payments — averaging $188.13 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 |
|---|---|---|
| Great Lakes Orthopedics | 1 | $1,200 |
| Axogen | 4 | $267 |
| Skeletal Dynamics Inc | 1 | $94 |
| Biocircuit Technologies Inc | 1 | $68 |
| Johnson & Johnson | 1 | $48 |
| Orthofix Medical, Inc. | 1 | $17 |
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
$1,693 in reported general payments places this provider in the 40th percentile of 498 orthopaedic surgery providers in Wisconsin.
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 | 12 | $37 |
Paid to pharmacies, not to this prescriber.
