Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (46.2%), travel and lodging and speaking fees — rather than concentrated in one kind of arrangement. 9 manufacturers reported payments, led by TELA Bio, Inc. at 29.9% of the total. Reporting peaked in 2019 at $803 and has fallen 73.8% since, to $211 in 2025. That places this record below the midpoint for colon & rectal surgery clinicians in MO, where the typical reported total is $4,503.
Across 22 payments — averaging $102.46 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 |
|---|---|---|
| TELA Bio, Inc. | 2 | $673 |
| Covidien LP | 1 | $400 |
| Conmed Corporation | 1 | $300 |
| Johnson & Johnson | 5 | $270 |
| Intuitive Surgical | 6 | $213 |
| Medtronic | 3 | $144 |
| Calyxo, Inc. | 1 | $140 |
| Medical Device Business Services, Inc. | 2 | $92 |
| Solventum Corporation | 1 | $22 |
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
$2,254 in reported general payments places this provider in the 40th percentile of 36 colon & rectal surgery 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 |
|---|---|---|
| Scopolamine | 26 | $364 |
| Neomycin Sulfate | 19 | $99 |
| Metronidazole | 38 | $92 |
| Ciprofloxacin Hcl | 19 | $52 |
| Ondansetron Hcl | 28 | $26 |
