Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (52.9%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. Octapharma USA, Inc. accounts for 68.9% of it on its own, with 3 other manufacturers making up the rest. Reporting peaked in 2019 at $4,650 and has fallen 99.8% since, to $11 in 2022. That places this record below the midpoint for hematology clinicians in CA, where the typical reported total is $4,615.
Across 8 payments — averaging $826.31 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

| Beigene USA, Inc. | 2 | $1,950 |
| Verastem, Inc. | 1 | $94 |
| Merck | 1 | $11 |
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.
