Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $14,530 of the $19,282 with a category attached, or 75.4%. Genentech USA, Inc. accounts for 71.9% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2024 at $12,368 and has fallen 57.9% since, to $5,213 in 2025. Among ophthalmology 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.

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
$19,282 in reported general payments places this provider in the 90th percentile of 773 ophthalmology 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

|---|---|---|
| ErythromycinErythromycin Base | 12 | $97 |
| Polymyxin B Sul-TrimethoprimPolymyxin B Sulf/Trimethoprim | 11 | $64 |
