Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $98,455 of the $106,159 with a category attached, or 92.7%. 16 manufacturers reported payments, led by GSK at 27.2% of the total. Reporting peaked in 2019 at $56,543 and has fallen 84.1% since, to $8,992 in 2025. Among internal medicine 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.
Across 107 payments — averaging $992.14 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
