Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $919,548 of the $919,548 with a category attached, or 100.0%. Otsuka Pharmaceutical Co., Ltd. accounts for 100.0% of it on its own, with 1 other manufacturer making up the rest. 2023 is the largest year on record at $347,780, more than ten times the $300 reported in 2019. Among rheumatology 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 79 payments — averaging $11,640 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.
