Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $17,683 of the $21,598 with a category attached, or 81.9%. 27 manufacturers reported payments, led by Medtronic at 31.1% of the total. Reporting peaked in 2023 at $7,954 and has fallen 63.1% since, to $2,939 in 2025. Among family clinicians in TX 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 708 payments — averaging $30.51 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
