Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 133 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 41 manufacturers, the largest accounting for just 12.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $4,665 and has fallen 50.1% since, to $2,328 in 2025. Among family medicine clinicians in NV 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 133 payments — averaging $116.86 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
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
$15,542 in reported general payments places this provider in the 95th percentile of 902 family medicine providers in Nevada.
