Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (46.3%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. 18 manufacturers reported payments, led by CSL Behring at 36.2% of the total. Reporting peaked in 2019 at $54,089 and has fallen 58.0% since, to $22,732 in 2025. Among allergy & immunology 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 178 payments — averaging $1236.84 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
