Payments from drug & device makers
What this record shows
The money is spread across several categories — other (42.7%), consulting fees and royalties or licence payments — rather than concentrated in one kind of arrangement. 23 manufacturers reported payments, led by Smith+Nephew at 46.7% of the total. Reporting peaked in 2022 at $639,890 and has fallen 88.4% since, to $73,996 in 2025. Among orthopaedic surgery clinicians in IN 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 766 payments — averaging $1724.30 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
