Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $149,764 of the $193,334 with a category attached, or 77.5%. Gilead accounts for 88.7% of it on its own, with 4 other manufacturers making up the rest. Reporting peaked in 2019 at $82,812 and has fallen 99.9% since, to $53 in 2025. Among infectious disease clinicians in IL 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 274 payments — averaging $705.60 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.

| Viiv Healthcare Company | 33 | $21,604 |
| Merck | 2 | $112 |

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.
