Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 116 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Alcon accounts for 73.2% of it on its own, with 13 other manufacturers making up the rest. Reporting peaked in 2021 at $1,454 and has fallen 55.7% since, to $644 in 2025.
Across 116 payments — averaging $56.78 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.

How this compares
$6,587 in reported general payments places this provider in the 85th percentile of 286 ophthalmology providers in Louisiana.
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.
