Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (53.3%), travel and lodging and grants — rather than concentrated in one kind of arrangement. Inari Medical, Inc. accounts for 89.3% of it on its own, with 16 other manufacturers making up the rest. Reporting peaked in 2019 at $5,283 and has fallen 97.1% since, to $152 in 2023. That places this record below the midpoint for interventional cardiology clinicians in KY, where the typical reported total is $7,951.
Across 77 payments — averaging $77.71 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
