Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 106 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 18 manufacturers, the largest accounting for just 16.3% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,408 and has fallen 92.3% since, to $109 in 2025.
Across 106 payments — averaging $21.02 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Biogen$363
- AstraZeneca$330
- Novartis$197
- UCB, Inc.$195
- AbbVie$173
- Neurocrine Biosciences, Inc.$159
- plus $811 from 12 others
What the payments were for
- Food & beverage$2,228100%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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 |
|---|---|---|
| Biogen | 24 | $363 |
| AstraZeneca | 10 | $330 |
| Novartis | 14 | $197 |
| UCB, Inc. | 7 | $195 |
| AbbVie(2 entities) | 11 | $173 |
| Neurocrine Biosciences, Inc. | 2 | $159 |
| EMD Serono, Inc. | 7 | $140 |
| Aucta Pharmaceuticals, Inc. | 7 | $109 |
| Sanofi | 5 | $102 |
| Lilly USA, LLC | 4 | $91 |
| Penumbra, Inc. | 1 | $79 |
| Amgen | 3 | $74 |
| Avanir Pharmaceuticals, Inc. | 3 | $52 |
| Teva Pharmaceuticals USA, Inc. | 2 | $49 |
| Boehringer Ingelheim | 2 | $44 |
| Genentech USA, Inc. | 2 | $36 |
| Philips North America LLC | 1 | $22 |
| Takeda Pharmaceuticals U.S.A., Inc. | 1 | $12 |
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
Too few clinical neurophysiology providers in Illinoisto place this figure against a meaningful peer group, so we don't.
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 |
|---|---|---|
| TecfideraDimethyl Fumarate | 11 | $94,347 |
| Aimovig AutoinjectorErenumab-Aooe | 21 | $16,056 |
| Levetiracetam | 108 | $6,274 |
| Lacosamide | 39 | $4,027 |
| Carbamazepine ErCarbamazepine | 28 | $3,181 |
| Gabapentin | 72 | $1,229 |
| Divalproex Sodium ErDivalproex Sodium | 17 | $1,086 |
| Memantine Hcl | 28 | $1,021 |
| Pregabalin | 27 | $1,002 |
| Oxcarbazepine | 13 | $1,000 |
| Primidone | 14 | $615 |
| Topiramate | 36 | $371 |
| Divalproex Sodium | 14 | $360 |
| Cyclobenzaprine Hcl | 29 | $155 |
| Donepezil Hcl | 19 | $133 |
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 | $363 | $94,34711 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. There are too few clinical neurophysiology providers in Illinoison file to place this against a meaningful peer group, so we don't.
