Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $300,874 of the $347,941 with a category attached, or 86.5%. Foundation Medicine, Inc. accounts for 61.8% of it on its own, with 14 other manufacturers making up the rest. Reporting peaked in 2019 at $186,366 and has fallen 100.0% since, to $47 in 2025. Among hematology clinicians in CA 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.
