Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (57.9%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 25 manufacturers reported payments, led by Regeneron Healthcare Solutions, Inc. at 54.6% of the total. Among retina specialist clinicians in CA 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 1,095 payments — averaging $1368.37 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Regeneron Healthcare Solutions, Inc.$819K
- Apellis Pharmaceuticals, Inc.$316K
- AbbVie$142K
- Genentech USA, Inc.$80K
- Alcon$34K

- plus $75K from 19 others

General payments by program year
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
$1,498,367 in reported general payments places this provider in the 95th percentile of 187 retina specialist providers in California.
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.
