Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.8% of the total across 102 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 22 manufacturers, the largest accounting for just 12.3% — the pattern of someone who eats at a lot of different presentations. Among obstetrics clinicians in IL with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 102 payments — averaging $21.65 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

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.
- ACCRUFER$112
How this compares
$2,208 in reported general payments places this provider in the 90th percentile of 42 obstetrics 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 |
|---|---|---|
| Estradiol | 12 | $1,227 |
| Mono-LinyahNorgestimate-Ethinyl Estradiol | 11 | $269 |
Paid to pharmacies, not to this prescriber.
