Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (57.8%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 14 manufacturers reported payments, led by Regeneron Healthcare Solutions, Inc. at 49.8% of the total. Reporting peaked in 2019 at $48,313 and has fallen 96.7% since, to $1,601 in 2025. Among dermatology clinicians in IL 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 178 payments — averaging $756.40 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.
