Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (43.7%), travel and lodging and consulting fees — rather than concentrated in one kind of arrangement. Synthes GmbH accounts for 76.8% of it on its own, with 6 other manufacturers making up the rest. 2025 is the largest year on record at $2,847, more than ten times the $13 reported in 2019. That places this record below the midpoint for orthopaedic trauma clinicians in MO, where the typical reported total is $16,093.
Across 13 payments — averaging $528.51 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 |
|---|---|---|
| Synthes GmbH | 6 | $5,279 |
| KCI USA, Inc. | 2 | $813 |
| Pioneer Surgical Technology, Inc. | 1 | $450 |
| AbbVie | 1 | $145 |
| Medical Device Business Services, Inc. | 1 | $137 |
| Johnson & Johnson | 1 | $29 |
| Boston Scientific | 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
$6,871 in reported general payments places this provider in the 30th percentile of 28 orthopaedic trauma providers in Missouri.
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 |
|---|---|---|
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 46 | $417 |
| Tramadol Hcl | 23 | $80 |
