Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 72 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 23 manufacturers reported payments, led by AbbVie at 30.6% of the total. 2025 is the largest year on record at $524, 2.1 times the $248 reported in 2021.
Across 72 payments — averaging $21.93 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| PfizerEliquis | $36 | $25,33131 claims |
| GSKTrelegy Ellipta, Breo Ellipta | $11 | $14,11427 claims |
| Johnson & JohnsonXarelto | $144 | $6,93213 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 70th percentile of 198 medical providers in Missouri.
