Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,292 of the $3,875 with a category attached, or 84.9%. 20 manufacturers reported payments, led by Boehringer Ingelheim at 26.4% of the total. Reporting peaked in 2019 at $1,599 and has fallen 72.2% since, to $445 in 2025. Among internal medicine clinicians in IL with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 156 payments — averaging $24.84 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
