Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 19 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 9 manufacturers, the largest accounting for just 22.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $844 and has fallen 93.0% since, to $59 in 2024. That places this record below the midpoint for neurology clinicians in MD, where the typical reported total is $1,345.
Across 19 payments — averaging $73.76 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

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
