Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.0% of the total across 16 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 11 manufacturers, the largest accounting for just 22.2% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $364 and has fallen 77.0% since, to $84 in 2025.
Across 16 payments — averaging $60.43 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Fresenius Kabi USA, LLC$214
- Eagle Pharmaceuticals, Inc.$171
- ICU Medical Inc$112
- Edwards Lifesciences$112
- Covidien LP$111
- Merck$76
- plus $171 from 5 others
Across 4 payments — averaging $28,561 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Merck$58K
- AstraZeneca$56K
What the payments were for
- Food & beverage$94798%
- Education$202%
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.
| Company | Payments | Total |
|---|---|---|
| Fresenius Kabi USA, LLC | 3 | $214 |
| Eagle Pharmaceuticals, Inc. | 2 | $171 |
| ICU Medical Inc | 1 | $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.
- BARHEMSYS$113
- Critical Care Hemodynamic Monitoring$112
- BIS$111
- FENTANYL CITRATE$110
How this compares
$967 in reported general payments places this provider in the 85th percentile of 1,980 anesthesiology providers in Illinois.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
