Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (59.1%), food and beverage and speaking fees — rather than concentrated in one kind of arrangement. Stryker accounts for 60.2% of it on its own, with 16 other manufacturers making up the rest. 2025 is the largest year on record at $2,088, 3.2 times the $660 reported in 2019.
Across 50 payments — averaging $79.25 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.

How this compares
$3,962 in reported general payments places this provider in the 65th percentile of 63 neurological surgery 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.
