Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (56.8%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. It is spread thinly across 42 manufacturers, the largest accounting for just 20.8%. Reporting peaked in 2019 at $131,398 and has fallen 53.2% since, to $61,527 in 2025. Among urology clinicians in CO 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 804 payments — averaging $878.68 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.
