Payments from drug & device makers
What this record shows
This record is dominated by travel and lodging: $3,577 of the $4,928 with a category attached, or 72.6%. 4 manufacturers reported payments, led by Astrazeneca UK Limited at 47.1% of the total. Reporting peaked in 2019 at $4,417 and has fallen 89.6% since, to $459 in 2023. Among internal medicine clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.

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.

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.
