Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (46.2%), education and food and beverage — rather than concentrated in one kind of arrangement. 14 manufacturers reported payments, led by Evologics LLC at 46.2% of the total. 2025 is the largest year on record at $41,710, 6.6 times the $6,363 reported in 2019. Among colon & rectal surgery clinicians in MO with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 85 payments — averaging $659.92 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares

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 |
|---|---|---|
| Gavilyte-GPeg3350/Sod Sulf,bicarb,cl/Kcl | 11 | $176 |
| Oxycodone Hcl | 21 | $51 |
