Payments from drug & device makers

What this record shows

This record is dominated by consulting fees: $21,350 of the $23,684 with a category attached, or 90.1%. Alcon Research LLC accounts for 81.7% of it on its own, with 11 other manufacturers making up the rest. Reporting peaked in 2021 at $13,500 and has fallen 93.6% since, to $862 in 2024. Among ophthalmology clinicians in CA 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.

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.

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

$23,684 in reported general payments places this provider in the 90th percentile of 2,513 ophthalmology providers in California.

Medicare billing

Part B allowed, 2024
$2,237,534
Medicare patients
940
Services billed
198,484

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.
