Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $114,370 of the $162,682 with a category attached, or 70.3%. 5 manufacturers reported payments, led by Gilead at 43.4% of the total. Reporting peaked in 2019 at $110,461 and has fallen 100.0% since, to $24 in 2024. Among infectious disease 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 240 payments — averaging $677.84 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.
| Company | Payments | Total |
|---|---|---|
| Gilead | 112 | $70,523 |
| Viiv Healthcare Company | 70 | $50,142 |
| Merck | 48 | $40,361 |
| Theratechnologies Inc. | 9 | $1,633 |
| Hologic Sales And Service, LLC | 1 | $24 |
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
$162,682 in reported general payments places this provider in the 95th percentile of 146 infectious disease providers in Colorado.
