Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $30,514 of the $35,203 with a category attached, or 86.7%. 8 manufacturers reported payments, led by Otsuka Pharmaceutical Co., Ltd. at 31.2% of the total. 2025 is the largest year on record at $17,566, more than ten times the $1,129 reported in 2019. Among internal medicine clinicians in MA 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 16 payments — averaging $2200.19 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
