Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $32,121 of the $44,357 with a category attached, or 72.4%. Modernatx, Inc. accounts for 66.6% of it on its own, with 4 other manufacturers making up the rest. Reporting peaked in 2022 at $22,643 and has fallen 90.0% since, to $2,275 in 2025. Among infectious disease clinicians in MO 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.
