Payments from drug & device makers
What this record shows
This record is dominated by ownership interests: $365,156 of the $514,030 with a category attached, or 71.0%. Anika Therapeutics, Inc. accounts for 80.3% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2020 at $368,189 and has fallen 90.7% since, to $34,195 in 2025. Among orthopaedic surgery clinicians in WI 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.

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
$514,030 in reported general payments places this provider in the 95th percentile of 498 orthopaedic surgery providers in Wisconsin.
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.
