Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $12,610 of the $17,521 with a category attached, or 72.0%. 35 manufacturers reported payments, led by Merck at 33.4% of the total. Reporting peaked in 2023 at $5,847 and has fallen 58.8% since, to $2,407 in 2025. Among medical 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 586 payments — averaging $29.90 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
