Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $8,213 of the $10,074 with a category attached, or 81.5%. Eli Lilly accounts for 87.5% of it on its own, with 13 other manufacturers making up the rest. 2025 is the largest year on record at $8,828, more than ten times the $369 reported in 2019. Among family medicine clinicians in KS 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 28 payments — averaging $359.78 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 |
|---|---|---|
| Hikma Pharmaceuticals USABuprenorphine-Naloxone, Buprenorphine Hcl | $35 | $28,932309 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 95th percentile of 1,469 family medicine providers in Kansas.
