Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $9,800 of the $16,057 with a category attached, or 61.0%. 16 manufacturers reported payments, led by Bausch & Lomb Americas Inc. at 53.4% of the total. 2025 is the largest year on record at $12,085, more than ten times the $100 reported in 2019. Among ophthalmology clinicians in MI 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 86 payments — averaging $186.70 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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
$16,057 in reported general payments places this provider in the 95th percentile of 674 ophthalmology providers in Michigan.
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 |

| Prednisolone Acetate | 38 | $1,505 |
| Difluprednate | 11 | $1,185 |
| Brimonidine Tartrate | 11 | $754 |
| Ketorolac Tromethamine | 17 | $323 |
| Timolol Maleate | 12 | $64 |
