Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 2 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Novartis accounts for 76.9% of it on its own, with 1 other manufacturer making up the rest. That places this record below the midpoint for pediatric hematology-oncology clinicians in CA, where the typical reported total is $536.
Across 2 payments — averaging $81.03 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Novartis$125
- Amgen$37
Across 55 payments — averaging $14,185 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Jazz Pharmaceuticals Inc.$687K
- E.r. Squibb & Sons, L.L.C.$56K
- Takeda Pharmaceuticals U.S.A., Inc.$24K
- Incyte Corporation$14K
What the payments were for
- Food & beverage$162100%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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.
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.
- PROMACTA$125
How this compares
