Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (52.2%), travel and lodging and consulting fees — rather than concentrated in one kind of arrangement. It is spread thinly across 36 manufacturers, the largest accounting for just 17.7%. Reporting peaked in 2020 at $3,639 and has fallen 69.2% since, to $1,119 in 2025.
Across 258 payments — averaging $44.65 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

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.

- LOKELMA$117
- Kerendia$113
How this compares
$11,519 in reported general payments places this provider in the 85th percentile of 55 nephrology providers in Kansas.
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.
