What this record shows
This record is dominated by consulting fees: $728,400 of the $728,400 with a category attached, or 100.0%. Baxter Healthcare accounts for 79.1% of it on its own, with 1 other manufacturer making up the rest. Among nurse practitioner 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.
