Payments from drug & device makers
What this record shows
This record is dominated by grants: $33,000 of the $45,186 with a category attached, or 73.0%. 27 manufacturers reported payments, led by Medtronic at 42.3% of the total. 2025 is the largest year on record at $20,393, more than ten times the $169 reported in 2019. Among internal medicine 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.
