Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $34,656 of the $51,027 with a category attached, or 67.9%. 4 manufacturers reported payments, led by Pfizer at 54.2% of the total. Reporting peaked in 2022 at $20,593 and has fallen 89.7% since, to $2,122 in 2025. Among endocrinology, diabetes & metabolism clinicians in NY 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.

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 |
|---|---|---|
| Pfizer | 7 | $27,646 |
| Genentech, Inc. | 4 | $12,762 |
| Novartis | 9 | $10,549 |
| Novo Nordisk | 1 | $69 |
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
$51,027 in reported general payments places this provider in the 90th percentile of 804 endocrinology, diabetes & metabolism providers in New York.

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 |

| Glimepiride | 11 | $68 |
Paid to pharmacies, not to this prescriber.
