Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $2,608 of the $2,945 with a category attached, or 88.6%. It is spread thinly across 18 manufacturers, the largest accounting for just 22.6% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for retina specialist clinicians in CO, where the typical reported total is $4,083.
Across 62 payments — averaging $47.49 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Genentech, Inc.$666
- Regeneron Healthcare Solutions, Inc.$644
- Astellas Pharma US Inc$415
- Eyepoint US, Inc.$200
- Notal Vision, Inc.$169
- Astellas Pharma Global Development$164
- plus $686 from 12 others
Across 73 payments — averaging $457.25 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

- Consulting fees$1505%

- Food & beverage$2,60889%

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.

| Regeneron Healthcare Solutions, Inc. | 14 | $644 |
| Astellas Pharma US Inc | 8 | $415 |

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
$2,945 in reported general payments places this provider in the 35th percentile of 51 retina specialist providers in Colorado.
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.
