Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (50.7%), ownership interests and royalties or licence payments — rather than concentrated in one kind of arrangement. American Rheumatology Network, LLC accounts for 99.0% of it on its own, with 20 other manufacturers making up the rest. 2025 is the largest year on record at $1,025,084, more than ten times the $1,118 reported in 2019. Among rheumatology clinicians in SC 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 323 payments — averaging $8824.35 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
