Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.9% of the total across 201 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 47 manufacturers, the largest accounting for just 20.3% — the pattern of someone who eats at a lot of different presentations. 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 201 payments — averaging $70.45 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.
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.
How this compares
$14,160 in reported general payments places this provider in the 95th percentile of 13,581 internal medicine providers in California.
