Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (59.5%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 14 manufacturers reported payments, led by Genentech USA, Inc. at 24.0% of the total. Reporting peaked in 2024 at $63,042 and has fallen 79.4% since, to $13,007 in 2025. Among neurology clinicians in OH 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.
Across 175 payments — averaging $880.06 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Genentech USA, Inc.$37K
- TG Therapeutics, Inc.$30K
- Sanofi$20K

- EMD Serono, Inc.$18K

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 |
|---|---|---|
| Genentech USA, Inc. | 37 | $37,036 |
| TG Therapeutics, Inc. | 35 | $29,784 |
| Sanofi | 15 | $19,685 |
| Biogen | 31 | $18,391 |
| EMD Serono, Inc. | 17 | $18,094 |
| Novartis | 26 | $14,750 |
| Amgen | 3 | $4,591 |
| Bristol Myers Squibb | 2 | $3,522 |
| E.r. Squibb & Sons, L.L.C. | 2 | $2,880 |

| Cycle Pharmaceuticals Inc | 1 | $1,300 |
| Genentech, Inc. | 2 | $108 |
| AstraZeneca | 1 | $16 |
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
$154,010 in reported general payments places this provider in the 90th percentile of 702 neurology providers in Ohio.
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

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| BiogenTecfidera, Avonex (4 Pack), Vumerity | $18,391 | $703,67064 claims |
| E.r. Squibb & Sons, L.L.C.Zeposia | $2,880 | $201,02517 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 90th percentile of 702 neurology providers in Ohio.
