Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 137 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 16 manufacturers, the largest accounting for just 15.1% — the pattern of someone who eats at a lot of different presentations.
Across 137 payments — averaging $21.31 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were for
- Food & beverage$2,919100%
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.
How this compares
$2,919 in reported general payments places this provider in the 80th percentile of 362 psychiatric/mental health providers in Nevada.
