Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $161,530 of the $187,650 with a category attached, or 86.1%. Mayne Pharma Commercial LLC accounts for 96.3% of it on its own, with 12 other manufacturers making up the rest. 2025 is the largest year on record at $85,051, more than ten times the $158 reported in 2019. Among obstetrics & gynecology 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 172 payments — averaging $1090.99 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
