Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $1,533,843 of the $1,708,441 with a category attached, or 89.8%. AbbVie accounts for 100.0% of it on its own, with 4 other manufacturers making up the rest. 2025 is the largest year on record at $498,022, more than ten times the $31,996 reported in 2019. Among internal medicine clinicians in WV 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 1,455 payments — averaging $1174.19 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
