Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 5 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. GSK accounts for 66.2% of it on its own, with 2 other manufacturers making up the rest. Reporting peaked in 2023 at $60 and has fallen 65.7% since, to $20 in 2024. That places this record below the midpoint for gynecologic oncology clinicians in IL, where the typical reported total is $1,540.
Across 5 payments — averaging $24.63 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- GSK$82
- Merck$21
- AstraZeneca$20
Across 3 payments — averaging $40,328 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.

What the payments were for

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 |
|---|---|---|
| GSK | 3 | $82 |
| Merck | 1 | $21 |
| AstraZeneca | 1 | $20 |
How this compares
$123 in reported general payments places this provider in the 5th percentile of 64 gynecologic oncology 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Dexamethasone | 12 | $105 |
Paid to pharmacies, not to this prescriber.
