Payments from drug & device makers
What this record shows

Stryker accounts for 61.8% of it on its own, with 16 other manufacturers making up the rest. Reporting peaked in 2019 at $2,234 and has fallen 82.7% since, to $387 in 2025.
Across 94 payments — averaging $75.83 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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
$7,128 in reported general payments places this provider in the 75th percentile of 35 foot & ankle surgery providers in Arkansas.
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
