Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $1,360 of the $1,980 with a category attached, or 68.7%. Alcon accounts for 65.3% of it on its own, with 10 other manufacturers making up the rest. Reporting peaked in 2019 at $1,506 and has fallen 78.2% since, to $328 in 2025. That places this record below the midpoint for retina specialist clinicians in VA, where the typical reported total is $1,967.
Across 16 payments — averaging $123.77 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
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.
| Company | Payments | Total |
|---|---|---|
| Alcon | 5 | $1,293 |
| Biotissue Holdings Inc. | 1 | $137 |
| Genentech USA, Inc. | 1 | $124 |
| Novartis | 1 | $109 |
| Glaukos Corporation | 1 | $104 |
| Astellas Pharma US Inc | 2 | $60 |
| US Oncology Corporate, Inc. | 1 | $39 |
| Regeneron Healthcare Solutions, Inc. | 1 | $35 |
| ANI Pharmaceuticals, Inc. | 1 | $34 |
| Apellis Pharmaceuticals, Inc. | 1 | $23 |
| Eyepoint US, Inc. | 1 | $22 |
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
$1,980 in reported general payments places this provider in the 50th percentile of 41 retina specialist providers in Virginia.
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 | 63 | $3,307 |
| Bromfenac Sodium | 13 | $1,058 |
| Ketorolac Tromethamine | 25 | $912 |
| Dorzolamide Hcl | 34 | $517 |
| Latanoprost | 31 | $475 |
